Which of the following statements is true?
Only somatic mutations are important to evolution because they can be inherited.
Acquired mutations are passed down from parent to offspring.
O Hereditary mutations are caused by external factors, such as radiation.
O Mutations are the most fundamental way to add new genes to a gene pool.
Answer: A,B, and C.) Only somatic mutations are important to evolution because they can be inherited. Acquired mutations are passed down from parent to offspring. Hereditary mutations are caused by external factors, such as radiation.
Explanation:
The true statement is: Mutations are the most fundamental way to add new genes to a gene pool.
A mutation is any alteration in the genetic material (i.e. nucleotide sequence) of the genome of an organism.
Mutations can be caused by both external (e.g., UV light) and endogenous (e.g., oxidative DNA damage) factors.
Mutation can be divided into somatic (body) cells and germline (gamete) cells. Only germline mutations can be inherited and pass from parents to offspring.
Acquired mutations are genetic alterations that are not present in the zygote, but are acquired sometime later in life. This type of mutation is involved in the development of cancer.
Mutations are the raw material on which natural selection operates, thus being the most important cause of evolutionary novelty.
In conclusion, mutations represent the most important source of genetic variability and a fundamental way to add new genes to a gene pool.

What is cell division ?
In a living organism there are two types of cell such as somatic cell and germinal cell which undergo the process of cell division.
Cell division occur which can be up two types such as mitosis and meiosis where mitosis is called as equatorial cell division as the number of daughter cell is equal to number of parent cell.
meiosis is called as reductional division as the number of daughter cell is half of the parent cell, occur in germ cell.

Define crossing over?
Answer:
Crossing over is the swapping of genetic material that occurs in the germ line. During the formation of egg and sperm cells, also known as meiosis, paired chromosomes from each parent align so that similar DNA sequences from the paired chromosomes cross over one another.
Explanation:
How does the decrease in biodiversity impact an ecosystem?
Answer:
because the more alike species are The more they have to adapt to try and compete with one another So the more different a species is the less they have to compete
Answer:
the decrease in biodiversity may cause a significant reduction in the productivity of the ecosystem. The loss of biodiversity means genetic variations are lost and the overall genetic pool reduces.

is dna synthesis apart of creating rna
Explanation:
One of the two strands of the DNA double helix then acts as a template for the synthesis of an RNA molecule. As in DNA replication, the nucleotide sequence of the RNA chain is determined by the complementary base-pairing between incoming nucleotides and the DNA template.

Mendel also wondered if the inheritance of one trait affected the inheritance
of another. He explored this possibility by performing is -
A. dihybrid crosses
B. back crosses
C. test crosses
D. monohybrid crosses
And after can y’all help me on others 3 so I can sleep it’s already 12
Answer:
A. dihybrid crosses
Explanation:
A dihybrid cross can be defined as a mating experiment between two lines/varieties/organisms that differ in two phenotypic traits. By using pea plants, Mendel performed dihybrid crosses in order to analyze the mode of inheritance of both phenotypic traits at the same time. From these mating experiments, Mendel observed that the inheritance factors (nowadays called genes) sorted independently from one another in the next generation, which is called the principle/law of Independent Assortment.

Help please describe how the biotic factors taiga differ from those in the rainforest
Answer: biotic factors include plants and animals. So, the rainforest animals are more adapted to warmer weather meaning they have less fur and are built for warmer weather. The plants in a rainforest need lots of water to survive as well as carbon dioxide so they have large, wide leaves.
In a Taiga biome, the animals have more fur and adaptations to help them to survive in colder weather. The plants primarily consist of fir and pine trees, which have waxy, needle-like leaves to retain water as well. The trees also dont lose their leaves in the winter.
Explanation:
The biotic factors are significantly found to be different in two types of habitation such as taiga and rainforests.
What are biotic factors?Biotic factors may be defined as those factors that are directly associated with living forms. It includes producers, consumers (herbivores, carnivores, and omnivores), decomposers, etc. It may also be characterized as any living thing that has a significant effect on an ecosystem.
The animals in the rainforests adapted to the average temperature that remains warm throughout the year and must be frost-free. So, the animals generally have less fur. While the plants require more water in order to survive and reproduce at a higher temperature.
The climatic conditions on taiga are actually cold as compared to the rainforests. So, the animals possess fur appearance in order to survive in low temperatures. The plants compose of waxy structures and needle-like leaves in order to retain water. The number of leaves remains the same throughout the year.
Therefore, the biotic factors are significantly found to be different in two types of habitation such as taiga and rainforests.

Answer: Everybody is born with different blood cells, skin tone etc . That depends on your parents and the actual spermatozoon that got to the egg and eventually turned out to be you . That means that is up to the genes and races that you’ve been mixed with and created of . Sometimes even siblings have slight differences in their skin tone ,eye color etc . The genes and races or stuff like that, that you’re mixed with may pop up in different ways for you and your siblings i don’t know if that makes sense
