Discuss 3 different types of mutations that can happen
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.

Answer:
Mammal 2 and 4 are most related, why?
Explanation: They have TCT, CAG, CTG and CA, the only ones it doesn't have is the last ones, A and G, making it the only difference. 1 has 2 differences to 2, 3 differences to 4, and 3 has 2 differences as well, therefore 2 and 4 have the least differences.
Answer:
2 and 4
Explanation:
You can see their patterns match except for the last letters of 2 and 4

Answer:
Typically, the nucleus of a cancer cell is larger and darker than that of a normal cell and its size can vary greatly. Another feature of the nucleus of a cancer cell is that after being stained with certain dyes, it looks darker when seen under a microscope
Explanation:
In contrast to normal cells, cancer cells don't stop growing and dividing, this uncontrolled cell growth results in the formation of a tumor. Cancer cells have more genetic changes compared to normal cells, however not all changes cause cancer, they may be a result of it.

What does every living thing have to have? *
Chloroplast
Nucleus
DNA
Answer:
DNA
Explanation:
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.

Which air mass would produce warm, humid weather in the summer?
Answer: maritime tropical air mass
Explanation: The oceanic tropical air mass regularly creates a warm, muggy climate in the mid-year. The air mass begins from over the warm water of the jungles and Gulf of Mexico, where warmth and dampness ordinarily move to the air above from the water beneath.
Use the table to answer the following question.
Gravity and inertia are the two forces that keep Earth in its orbit as it travels around the Sun. What would happen if the force of inertia disappeared?
A.
Earth would break apart.
B.
Earth would be pulled into the sun.
C.
Earth would leave the solar system.
D.
There would be no changes in Earth's orbital path
Answer:
D.
Explanation:
if the force of inertia disappeared there would be no changes in earth's orbital path.
the reasons is that earth would stop moving as soon as there was no longer any force being applied

Answer:
The growth rate is 20+ Falcons are born per year.
Explanation:
Hope this helps!
Answer:
Population in the world is currently (2020) growing at a rate of around 1.05% per year (down from 1.08% in 2019, 1.10% in 2018, and 1.12% in 2017). The current average population increase is estimated at 81 million people per year. Annual growth rate reached its peak in the late 1960s, when it was at around 2%.

in VDJ recombination occurs in the Group of answer choices variable region of the heavy chain. constant region of the light chain. variable region of the light chain. Both the light and heavy chain.
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.
OD. Most of striped frogs have the genotype Ss and the unstriped frogs have the genotype ss.

What makes a species successful in an ecosystem?
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.

hellllllllllllpp meeeeeeeeee pllllllllsssss..
Answer:
Yes; When the cell grows larger,, it needs more cell membraine to prepair for mitosis. Without this process, the cell would rupture.
Yes; The cell would not be able to grow if the surface area stayed the same.
