Explanations;
Label the figure below. Word bank: leading strand, lagging strand, DNA
polymerase, DNA helicase, replication fork
Answer:
DNA can replicate itself because its two strands are complementary. This means that one strand can be used as a template to make the other strand. It happens right before cell division via mitosis or meiosis so that each new daughter cell can have a complete genome.
Before replication can start, the double strands of DNA need to separate from each other. An enzyme called DNA helicase breaks the hydrogen bonds that connect the two strands, allowing them to come apart.
The point where this unzipping starts is called an origin point. Eukaryotic DNA can have more than one origin point, but prokaryotes can only have one.
The points where DNA is currently unwinding are called replication forks.

How is the equilibrium constant calculated?
figure 12-1 shows the structure of an
A. DNA molecule
B. amino acid
C. RNA molecule
D. protein
Answer:
A
Explanation:
as is double helix and it also contain thymine which is only in DNA and RNA has uracil.
hope this make sense:)
Macromolecules like proteins and nucleic acid are large structures that are essential for biochemical processes. The figure shows the structure of DNA.
What is DNA?DNA is deoxyribonucleic acid that is a nucleic acid and is an important genetic material found in living organisms. It is composed of a double helix structure.
The nucleotide structure of the DNA constitutes deoxy sugar, phosphate groups, and nitrogenous bases like adenine, thymine, guanine, and cytosine.
It cannot be RNA as in RNA, uracil is present at the place of thymine. It cannot be an amino acid or protein as well because they are not composed of the amine, carboxylic, and the R group.
Therefore, the given figure is option A. DNA molecule.

A. Hypertonicity
B. Dynamic Equilibrium
C. Homeostasis
D. Osmolarity
Answer:
B. Dynamic Equilibrium
Explanation:
The result of diffusion is a gradual mixing of material such that the distribution of molecules is uniform. Since the molecules are still in motion, but an equilibrium has been established, the end result of molecular diffusion is called a "dynamic equilibrium".
Answer:
B. Dynamic Equilibrium
Explanation:
When the particles are equally spaced apart they have reached Dynamic Equilibrium.

A. El átomo de Thomson se caracteriza por ser esférico, con carga positiva, con electrones partículas alfa α partícula rebotada incrustados en él
Answer:
Debido a la presencia de partículas pesadas.
Explicación:
Debido a la presencia de carga positiva en el núcleo del átomo de Thomson, las partículas alfa α rebotaron cuando chocaron con el protón porque el protón es una partícula pesada y la presencia de neutrón la hace más pesada. Debido a la presencia de partículas pesadas en el núcleo, las partículas alfa no pueden atravesarlo. Solo puede pasar a través del átomo de Thomson donde hay un espacio vacío en el átomo.

An examination of racial classifications from around the world indicates that Group of answer choices the best racial classifications are based solely on phenotypic traits. all cultures classify races similarly. the best racial classifications are based solely on genotype. the classification of racial types is an arbitrary, culturally specific process. the best racial classifications are based on both genotype and phenotype.
Answer:
the classification of racial types is an arbitrary, culturally specific process.
Explanation:
Racism can be defined as an act, practice or policy by an individual, group of people or institutions which typically involves promoting the ideas and belief that a race is superior in comparison with another. Thus, it simply means the believe that a particular race has dominance over another (an inferior race).
An examination of the classifications of races from around the world indicates that the classification of racial types such as Africans, Americans, Indians, Asians, Black-Americans, Hispanics, etc., is typically based on individual perception, not objective and an impulsive (arbitrary), culturally inclined or specific process.
This ultimately implies that, the classification of racial types is considered not to be based on any form of objective distinction but may be defined by a person's culture.
A culture can be defined as the general way of life of a group of people living together in a particular location or society.
Basically, culture comprises of beliefs, values, behaviors, language, dressing, cuisine, music, symbols, arts, social habits, knowledge, customs, laws pertaining to a particular group of people living together in a society.

For those individuals who have an allergic reaction to cats, a company in Los Angeles promises relief. They offer a new line of cats genetically modified to eliminate or reduce their allergy-causing properties. The development of this new line of cats most likely involved A. using natural selection to produce a new variety of cat B. altering the reproductive rate of cats C. changing the behavior of cats D. manipulating the DNA of cats
Answer: D. manipulating the DNA of cats.
Explanation:
Deoxyribonucleic acid (DNA) refers to the organic chemical which consists of genetic information. The DNA can be found in the cells of organisms.
Since the new line of cats are genetically modified to eliminate or reduce their allergy-causing properties, then we can infer that the DNA of the cats have been manipulated. In this case, the allergy causing property won't be passed across to the offspring since the DNA has been manipulated.

A guard bees job is to protect the hive from intruders, a job that can lead the guard bee to sacrifice its own life. If the guard bee cannot reproduce, how do genes for altruism increase in the population
Answer:
Altruism genes are dominant, so they can be inherited more easily. Bee colonies are so large that the loss of a few individuals will not affect the gene pool.
Explanation:
The altruistic genes are easily and sophistically inherited from the parents to their offspring. These genes are dominant that increase the size of the population by sacrificing their own life for the benefit to pass their genes to the next generation.
What do you mean by Altruism?Altruism may be defined as a behavior in which one individual sacrifices their own fitness value to increase the fitness value of the other individual that is genetically as well as closely related.
Altruistic behavior is often associated with Kin selection. The genes for altruism are exposed to the population directly from the parents and then passes to the offspring.
Therefore, it is well described above.

According to the site, what are the views and approaches for psychodynamic therapy and humanistic therapy?
Answer:
In psychodynamic therapy, therapists help people review emotions, thoughts, early-life experiences, and beliefs to gain insight into their lives and their present-day problems and to evaluate the patterns they have developed over time. Recognizing recurring patterns helps people see the ways in which they avoid distress or develop defense mechanisms as a method of coping so that they can take steps to change those patterns.
Explanation:
Answer: In psychodynamic therapy, therapists work with patients to examine their feelings, thoughts, early experiences, and beliefs in order to acquire understanding of their lives, their current issues, and the patterns that have grown over time. People can take action to change repeating behaviors by being aware of how they avoid distress or establish defense mechanisms by recognizing these tendencies.

Answer:
a chordate.
Explanation:
Taxonomy can be defined as the process of naming, classification and description of living organisms such as plants and animals. The eight (8) biological classification (taxonomy) used for grouping and organizing organisms are; kingdom, domain, phylum, family, order, class, species and genus.
Generally, taxonomy helps scientist to have a good understanding and knowledge when studying various organisms.
A chordate can be defined as an animal found in phylum chordata of the animal kingdom such as vertebrates, cephalochordates, tunicates, etc.
The four (4) shared anatomical features or characteristics of chordates includes the following;
I. Notochord.
II. Dorsal hollow nerve cord.
III. Pharyngeal slits.
IV. Post-an_al tail.
In this scenario, you find a small, elongated animal that has segmental musculature, a coelom, and a complete digestive tract. Thus, this animal is a chordate.
