If a drug was administered that would impede the binding of NAD+ to electrons what steps of cellular respiration would this substance affect
Answers
Answer:
The correct answer is - not getting all NAD+ so burning more ATP to make up for the energy loss.
Explanation:
If the drug was administered and it would cause impedetion of the binding of NAD+ to electrons which causes decrease availability of the NAD+ that leads to less energy formation due to the use up more ATPs in the process of cellular respiration.
If NADH couldn't be formed as NAD+ will not binding, the cells will lose out on ATP produced. It will lead to weight loss due to burning out more ATP to make up for the energy loss.

In your opinion, what is the WORST Environmental Impact of Invasive Species? Ready? Enter your answer here.
Answers
Answer:
destruction of native species
Explanation:
Invasive species are destructive. They ruin ecosystems in which everything has a role, and all niches are full. With an invasive species, such as Pablo Escobar's hippos. A drug lord of South America had several hippos transported to his estate. Even after he died, the hippos flourished in South America. This was a perfect environment for the hippos as they had plenty to eat, and no threat where in Africa they would compete with lions, crocodiles and such. But the hippos just kept multiplying, eating food otherwise for native species, and destroyed the land with their size. The hippos endangered several species in the surrounding area at the cost of their easy living, as well as the people around.
Long story short, destruction of native species.

Enhancerless GFP reporter constructs used in research conducted in mice contain a generic mouse gene promoter (TATA box) followed by a transcription start site and then a GFP gene cDNA. When such enhancerless reporter gene constructs are integrated into random locations in the mouse genome, about 10% of the time, high levels of tissue-specific GFP expression are detected, even though the reporter gene construct itself has no enhancer. How is this possible
Answers
Answer:
the reporter gene can randomly insert near to an enhancer sequence which can induce its expression
Explanation
Enhancers are genetic sequences capable of activating gene expression by binding to specific proteins (e.g., transcription factors). Enhancers can regulate the expression of nearby genes located thousands of nucleotides away, i.e., over several kilobases away. In the human genome, it is well known that enhancers are scattered across the 98% of the genome. In this case, it is expected that the reporter GFP gene construct is randomly inserted near an enhancer sequence (a 10% chance of insertion), thereby being regulated by that enhancer.

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
Answers
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.

Punnett square drawn below:
Explanation:
Sorry if it's messy. Since brown coat is dominant to black coat, that would mean that the genotype for brown is either Aa or AA. Since it says it's a pure breeding brown mouse and that all of the offspring are brown, that means that the genotype for the pure breeding brown mouse is AA. As for the black coated mouse, black is reccessive, meaning the genotype would be aa. So... AA x aa = 100% Aa
Polycomb group (PCG) gene mutants cause ectopic expression of Antennapedia (Antp) and other homeotic genes. The PCG protein encoded by the PgG gene has a domain that binds to methylated histone H3. This finding supports which of the following hypotheses?
a) that PCG mutants lack Antp mRNA compared to the wildtype
b) that PCG repress transcription by interacting with chromatin
c) that PCG binds to Antp genes and serves as a transcription activator
d) that PCG activates Antp genes in tissues
e) that PCG is allosteric activator of RNA polymerase II
Answers
Answer:
b) that PCG repress transcription by interacting with chromatin
Explanation:
The Polycomb-group (PcG) proteins are evolutionarily conserved proteins in all higher eukaryotes which are involved in establishing epigenetic silencing of developmental genes. In animals, the PcG proteins are well known to form complexes capable of silencing target developmental genes by modulating chromatin structure during embryo development. In Drosophila melanogaster, the Polycomb repressive complex 2 (PRC2) is known to catalyze the trimethylation of lysine 27 on histone H3 (i.e., H3K27me3), thereby silencing homeotic (Hox) developmental genes. The core of the Drosophila PRC2 complex is composed of Enhancer of zeste [E(z)], Suppressor of zeste 12 [Su(z)12], and Extra sex combs (Esc) proteins. The E(z) protein is a well-known histone methyltransferase that maintains the methylation status of Hox genes, thereby silencing their expression during embryo development.
If a nucleotide is removed from a gene, the order of nucleotides will shift, resulting in new 1. _______ being coded for. These will combine to form a different 2._______ than what the 3._______ originally coded for.
Answers
Answer:
Amino acid; protein; gene.
Explanation:
Genomics refers to the scientific study of genes (DNA) found in living organisms such as humans and animals.
A gene can be defined as a complete set of hereditary instructions that is typically found in the deoxyribonucleic acid (DNA).
A nucleotide can be defined as an organic molecule which forms the building block of nucleic acid such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
Simply stated, a sequence of biomolecules which are responsible for coded genetic instructions in all living organisms is known as nucleotides.
Basically, nucleotide comprises of the following parts;
1. Nitrogenous base: this includes adenine (A), thymine (T), guanine (G), and cytosine (C) which are mainly found in the DNA while adenine (A), guanine (G), uracil (U) and cytosine (C) are found in the RNA.
2. A phosphate group.
3. A penrose sugar: it is either deoxyribose in DNA or ribose in RNA.
Furthermore, the two parts or chemical components of a nucleotide which do not change throughout the structure of DNA are;
I. Five-Carbon Sugar also known as deoxyribose and it has hydrogen on its second carbon.
II. Phosphate: this is the structural backbone that provides support to DNA.
Additionally, the proteins which are mainly synthesized based on the genetic instruction codes in deoxyribonucleic acid (DNA) determines the trait of living organisms.
Genome editing can be defined as a high-tech process which avail scientists the opportunity or ability to remove (delete), replace and insert Deoxyribonucleic Acid (DNA) sequence in a living organism such as bacterias, animals, plants etc in order to correct a genetic disorder and to improve on their physical and chemical conditions.
Hence, when you remove a nucleotide from a gene, the order of nucleotides shifts and as such resulting in new amino acid being coded for. These new amino acid will combine to form a different protein than what the gene was originally coded for.

For example, the drug may contain all relevant components of a nucleotide, including a proper purine or pyrimidine base, but lack the 3' OH group. How would this modification allow this drug to prevent viral DNA synthesis
Answers
This modification allows the drug to prevent viral DNA synthesis by different mechanisms as an enzyme DNA polymerase follows.
What do you mean by DNA synthesis?DNA synthesis may be defined as the biological process by which a deoxyribonucleic acid (DNA) molecule is created.
The enzyme DNA polymerase adds some of the nucleotide bases to the strand that contains 3'-OH at the end. But when the end part of the strand lacks the 3' OH group, it inhibits the process of DNA transcription.

chilly in January and February (usually 15° C or 60° F), water stays liquid.
Then, when our area's temperature gets really hot in the summer (usually
about 40° C or 100. F), the water in the pool is still a liquid. It would have

Remember, though, that water does not have to boil to turn to a gas.
Some of the water evaporates at all temperatures. Water temperature is a

have more kinetic energy than others. The molecules that have enough
kinetic energy to break the bonds with other molecules can leave the
liquid and move off into the air. That is why you have to keep filling up the
