Answer:
transformation is carried out by random uptake of DNA, and transduction by a bacterial virus
Explanation:
Transformation and transduction are two of the three processes bacteria uses in genetic recombination (the third being conjugation). As rightly stated in the question, both processes establish that DNA is the genetic material of most living organisms and they both involve transfer and expression of DNA from cell to cell.
However, both processes are different in the way they get the foreign DNA into the bacteria cell.
- Transformation involves the random uptake of foreign extracellular DNA by the host bacterial cell.
- Transduction involves the transfer of foreign DNA into a bacteria cell via a virus called BACTERIOPHAGE. N.B: A bacteriophage is a virus that infects a bacteria host.

An adult hemopoietic stem cell found in the bone marrow ______________________. (a) will occasionally produce epidermal cells when necessary. (b) can produce only red blood cells. (c) can undergo self-renewing divisions for the lifetime of a healthy animal. (d) will express all the same transcription factors as those found in an unfertilized egg.
Answer: (c) can undergo self-renewing divisions for the lifetime of a healthy animal.
Explanation:
The adult hematopoietic tissue or adult hematopoietic stem cells can be found in bone marrow of the animal. These cells have the ability to regenerate and renew so that the production of red blood cells remains continuous till death. Hematopoiesis can be defined as the production of cellular components of blood. The adult hematopoietic stem cells are located in the flat bones and ends of the long bones.
define the process of photosynthesis
Answer:
The process by which the green plants prepare their food in presence of sunlight , water and carbon dioxide is called photosynthesis.

How does lateral gene transfer help explain the evolution of antibiotic resistance in bacteria?
Answer:
Lateral gene transfer allows the bacteria to develop resistance to antibiotics and spread it between bacterial populations. ... This process allows bacteria to transfer genes from one population into another. As a result, the next generation would evolve and develop defenses that would make them resistant to the drug.

What are four examples of learned behaviors in animals?
Answer:
Habituation. Sensitization. Classical conditioning. Operant conditioning.Explanation:
Types of learning include habituation, sensitization, classical conditioning, operant conditioning, observational learning, play, and insight learning. One of the simplest ways that animals learn is through habituation, where animals decrease the frequency of the behavior in response to a repeated stimulus.
1. This question may be completed independently or as a group exercise. Biological anthropologists disagree about the best way to classify the robust australopithecines. Describe the two approaches to classifying these species. Which classification do you support
Answer:
Some researchers classify Australopithecines into gracile australopithecines and robust australopithecines, while others argue that differences are enough strong to classify robust australopithecines in their own genus called 'Paranthropus'. In my opinion, it seems reasonable to obtain more fossil data in order to support this division
Explanation:
The term Australopithecines comes from the genus Australopithecus, which are the closest known relatives of our genus Homo, and arose around three (3) million years ago. Australopithecines can be classified into two major groups called gracile australopithecines and robust australopithecines. However, robust australopithecines have also been classified in their own genus, Paranthropus, in order to distinguish them from the gracile australopithecines. The major differences between gracile and robust species are associated with facial and cranial features. Paranthropus species had a large sagittal crest, enormous cheek teeth, robust jaws, and strong jaw muscles (suggesting they were herbivores that ate tough food). However, these main features may not be conclusive evidence that supports the separation of Paranthropus in its own clade, thereby in my opinion it should be reasonable to wait until more fossils are found in order to correctly classify Paranthropus species as a different group.

Which of the following explains the conservation of mass during cellular respiration? (4 points) a The total number of atoms when carbon dioxide and oxygen react stays the same when glucose and water are produced. b The total number of atoms when water and oxygen react stays the same when glucose and water are produced. c The total number of atoms when carbon dioxide and water react stays the same when glucose and oxygen are produced. d The total number of atoms when glucose and oxygen react stays the same when carbon dioxide and water are produced.
Answer:
D- The total number of atoms when glucose and oxygen react stays the same when carbon dioxide and water are produced.
Explanation:
The conservation of mass during cellular respiration can be explained by the fact that after cellular respiration which occurs due to the oxidation of glucose to produce carbon dioxide and water, the number of atoms on the right hand side (RHS) of the reaction remain same as of left hand side (LHS) of the reaction.
The balanced chemical equation is mentioned as under:
C₆H₁₂O₆ + 6 O₂ -> 6 CO₂ + 6H₂O + Energy.
(Glucose) (Oxygen) (Carbon (Water)
dioxide)
If we will see carefully, the number of atoms of each element on RHS & LHS of the equation are same i.e. there are 6 atoms of C, 18 atoms of O and 12 atoms of H on both the sides.

What is resource partitioning and how is it an adaptation to competition? Provide an
example.
Definition:
Resource partitioning is the division of limited resources by species to help avoid competition in an ecological niche.
In any environment, organisms compete for limited resources, so organisms and different species have to find ways to coexist with one another.
Example:
Some lizard species appear to coexist because they consume insects of differing sizes.

Reverse transcriptase is an enzyme normally found in association with retroviral activity. Which of the following statements is true. Question 48 options: the enzyme requires no template more than one of the choices is correct the enzyme is catalytically similar to telomerase the enzyme can synthesize DNA from an RNA template the enzyme can synthesize of RNA from a DNA template
Answer:
The true statement about Reverse Transcriptase is:
the enzyme can synthesize DNA from an RNA template
Explanation:
Reverse transcriptase or transcription synthesizes the enzymes of a DNA molecule using an RNA template. The resulting DNA, which is usually called cDNA or complementary DNA, can be used for the amplification of PCR (polymerase chain reaction). When the reverse transcription is followed by PCR, it is known as reverse transcription-PCR (RT-PCR), which is a combined laboratory technique.

Circle the pairing of organisms from Model 3 that you predict would have the most divergence in their DNA. Support your choices with a group discussion about morphology (observable characteristics and structure), ecology, and lifestyles of the animals
a. whale and human or whale and tuna
b. pig and rhesus monkey or pig and chicken
c. tuna and fly or tuna and chicken
Answer:
a. whale and tuna
b. pig and chicken
c. tuna and fly
Explanation:
Following, you will find characteristics of each species that differ in the contrasting groups. These descriptions reflect the divergence degree between groups.
a. whale and tuna
Whales: Vertebrate and Big-sized marine mammals. They are long-lived and pulmonate animals. They are relatively slow, and only breathe while they are on the surface, opening the blowhole which covers the narines. Despite being mammals, they lack hair, so they have naked soft skin. They have one dorsal fin, two lateral flippers, and a caudal horizontal fin, which they move up and down. They are viviparous, with internal fecundation, and females carry mammal glands to feed their offspring. They feed on krill and other small animals, which they filtrate using their baleens. Whales exhibit the Type I survivorship curve. Mortality often occurs at the end of the cycle. They have long cycles of life and high probabilities to survive until they are old enough. These species have few descendants and spend too much time and energy in parental care to ensure their reproductive success. They are used to swim deep depth or near the surface depending on the reproductive cycle stage. Tuna: Bony marine fish. Fusiform and medium-sized body, fast swimmers. They can live for 15 years. Their body is covered with scams. They have two dorsal fins, two ventral fins, two lateral fins, and a caudal fin which they move from side to side. It swims near the surface and interchange gas using the grills. They have many teeth and feed on anything they can, such as small fishes, zooplankton, crustaceans, and mollusks. They have external fecundation and exhibit the Type III survivorship curve. Significant mortality during the early stages of life. Only a few individuals reach the later life stages, getting to survive their first period of life. Survivors usually have a long life. These species produce big offsprings at the same time, but they provide little or no parental care. Their reproductive success relies on the number of descendants.b. pig and chicken
Pigs: Heary Mammal, with thick hairs, called bristles and mammal glands. They are four-legged, have hooves and four fingers. Their snout is long and flexible, with sharp teeth. They have a curly tail and thick and sensitive skin. Naturally, they are herbivorous but became omnivorous in captivity. They can live for ten or fifteen years. Viviparous. Well-developed smell sense and no sudoriparous glands. Territorial, dominant, and highly communicative with partners. They can use more than twenty different sounds. They also exhibit the Type I survivorship curve.Chickens: Birds. They have two legs and two wings however, it has never been successful in flying. Their body is cover by feathers. They have no hair, and they do not have teeth either, but they have a corneous peak instead. They are omnivorous. They show sexual dimorphism, especially in feathers and crests. They exhibit the type II survivorship curve. The probabilities of dying are equals all along the cycle, at any age interval. The number of dead individuals remains constant from the beginning to the end of the life cycle. These species have reduced offsprings, and they ensure their reproductive success by providing some significant parental care.c. tuna and fly
Tuna: Already described aboveFly: Flying and small-sized Insects. Dipterous, with their bodies divided into three regions: Head, thorax, and abdomen. They have six appendixes to walk, one pair of wee-developed wings, one pair of vestigial wings, eyes very sensitive to light. The mouthparts are used to lick, suck or bite. Some species can sting and suck blood from humans. Their body is covered with thin hairs and sensory bristles used to taste, feel, and smell. They are attracted by smelly matter, from which they feed on. In general, flies are associated to matter in decomposition and wastes. They have a short life cycle and can live up to twenty-five days. Ovoviviparous species, laying too many eggs that will turn into larvae and finally to the adult fly stage.Based on Model 3, the pairing of organisms that would have the most divergence in their DNA is: A. whale and human or whale and tuna.
What is genetics?Genetics can be defined as the scientific study of genes, chromosomes, heredity and the similarities or divergence (variations) of traits (DNA) in living organisms such as animals, humans, and plants.
Based on morphology and ecology, whales are aquatic and gigantic vertebrate (mammals) that only live in water. Also, whales are pulmonate and carnivorous animals that feed on other animals.
From Model 3, the number of amino acids differences between whale and human is ten (10) while that of whale and tuna is equal to seventeen (17). Therefore, we can deduce that the pairing of organisms that would have the most divergence in their DNA is whale and human or whale and tuna.

Carrying capacity is Group of answer choices seldom reached by marine producers and consumers because of the vast resources of the ocean. the maximum population size that a particular environment can support. fixed for most species over most of their range most of the time. the term used to describe the stress a population undergoes due to limited resources.
Answer:
the maximum population size that a particular environment can support.
Explanation:
A population can be defined as the total number of living organisms living together in a particular place and sharing certain characteristics in common.
Generally, these populations may be divided into a fraction of the population (subpopulation) based on certain factors and reasons.
Population regulation can be defined as a biological process that balances limiting factors affecting the growth of a population based on density. The factors that regulate the growth of a population are divided into two (2) main categories and these includes;
I. Density-independent factors.
II. Density-dependent factors.
Density-dependent are regulating factors such as predation, diseases, and competition that affect the size of the population of living organisms through decreasing or increasing mortality and birth rate.
Furthermore, density-independent factors do not have an increasingly greater effect as a population's density increases. Thus, its effect are reduced as a population's density increases in size.
Carrying capacity is the maximum population size that a particular environment can support. The carrying capacity of an environment is denoted by the letter k.
