Answer 1

Answer:

A: maintains genetic continuity from one generation to the next

Explanation:

I think A is correct because it mains genetic continuity from one generation of cells to the next. So all you cells in skin that are dead are replaced by the exact replica of next skin cells that arose from mitosis.

Gametes undergo meiosis and not mitosis.

Answer:

Explanation:

Los cloroplastos son los orgánulos celulares que en los organismos eucariotas fotosintetizadores se van ocupando de la fotosíntesis. Están limitados por una envoltura formada por las dos membranas concéntricas y contienen muchas vesículas, los tilacoides, donde se encuentran organizados los pigmentos y demás moléculas que convierten la energía lumínica en energía química, como la clorofila.

El término cloroplastos sirve alternativamente para designar a cualquier plasto dedicado a la fotosíntesis, o específicamente a los plastos verdes propios de las algas verdes y las plantas. Aunque el reciente descubrimiento adiciona a más individuos en la lista, como lo es en el caso de Elysia chlorotica, que al digerir al alga Vaucheria litorea, adquiere los cloroplastos a sus tejidos, y gracias a esto, puede realizar la fotosíntesis.

Explain Newton’s First Law and give an example of it

Answers

Answer:

When a person jumps out of a moving vehicle, he falls forward due to inertia of motion. One example of Newton's first law in real life is, when you are walking with a glass filled with water, you will notice that the water spills at certain locations when you walk at faster pace. The water inside the glass will remain at rest until you move.

Explanation:

Answer:Newton's first law states that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.

An object at rest stays at rest.

What makes a species successful in an ecosystem?

Answers

Answer:

Beside the intensive loss of forest cover [2], fragmentation of the pristine remnants further affects species [3] and limits their ability to move into adequate areas. Thus the ability to cope with altered landscapes is crucial for the persistence of a species, especially in the face of climate change.

12. Which has NOT been linked to acid precipitation?
a. Toxic metal poisoning
b. Lower blood pH
c. Respiratory problems
d. Damaged monuments

Answers

Answer:

Explanation:

Lower blood pH has not been linked to acid precipitation. So, the correct option is (B).

What is Acid Precipitation?

Acid rain is defined as rain or any other form of precipitation that is abnormally acidic, meaning that it contains high levels of hydrogen ions. Most water which include drinking water, has a neutral pH that exists between 6.5 and 8.5, but acid rain has a pH level lower than this and averages between 4–5.

Acid rain can be caused by natural causes, such as volcanic eruptions, while acid rain can also caused by human activities such as the burning of fossil fuels, manufacturing, oil refineries, electricity generation, and vehicles, all of which release sulfur and nitrogen oxides into the atmosphere.

Thus, lower blood pH has not been linked to acid precipitation. So, the correct option is (B).

Answers

Answer:

constant region of the light chain.

Explanation:

The VDJ recombination is defined as the process where the T cells as well as the B cells are randomly assembled from the different gene segments. These are mainly known as the variables (V), the diversity (D) and the gene (G). This is done in order to generate the unique receptors which is also called as the antigen receptors so that they can collectively recognize the different types of the molecules. It mainly occurs in the constant region of the light chain.

There is a species of frog on an island that puzzles scientists. The proportion of frogs with no stripes is greater than the proportion of frogs with
stripes. This is puzzling because the unstriped trait is recessive (s), and the striped patterns are due to dominant alleles (S). Also, natural selection
seems to support the striped trait.
How do genetic factors most likely account for the proportion of traits in the frog population?
A. Most of striped frogs and unstriped frogs have the genotype ss.
OB. Most of striped frogs have the genotype SS and the unstriped frogs have the genotype ss.
C. Most of striped frogs have the genotype SS and the unstriped frogs have the genotype Ss.

Discuss 3 different types of mutations that can happen

Answers

Answer:

Explanation:

Un cambio en la secuencia de bases en el ADN o ARN se conoce como mutación . ¿La palabra mutación te hace pensar en ciencia ficción y monstruos con ojos de insecto? Piensa de nuevo. Todos tienen mutaciones. De hecho, la mayoría de las personas tienen decenas o hasta cientos de mutaciones en su ADN. Las mutaciones son esenciales para que ocurra la evolución. Son la fuente principal de todo el material genético nuevo -nuevos alelos - en una especie. Aunque la mayoría de las mutaciones no tienen efectos en los organismos en que ocurren, algunas mutaciones son beneficiosas. Incluso las mutaciones dañinas rara vez causan cambios drásticos en los organismos.

there are 3 types of mutations, base substitutions - single base mutations are called point mutations. Point mutations are the most common type of mutation and there are two other types. point mutations occur in DNA sequence seconding proteins are either silent, missense or nonsense. Deletions is the second type of mutation, this results when one or more base pairs are lost from the DNA. If one or two based are deleted the translation frame is altered resulting in a garbled message and nonfunctional product. A deletion of three or more bases leave the reading frame intact. A deletion of one or more corona result in a protein missing or more amino acids. this may be deletions or not. And lastly insertions this is when you have additional base pairs which may lead to frameshifts depending on whether or not multiples or three base pairs are inserted. combinations of insertions and deletions leading to a variety of outcomes are also possible.
