Answer:
Mitosis
Explanation:
Mitosis is not a source of genetic mutation because it take place mostly in the somatic cells. This is because it does not lead to the production of gametes . In mitosis, the parent cells divide into two daughter cells and each daughter cells are genetically identical to the parent cell because they carry the same number of chromosomes as the parent cell. There is no genetic variation in this.
Which of these is a difference between DNA and RNA?
DNA is found in the nucleus; RNA is never found in the nucleus.
DNA consists of five different nucleotides; RNA consists of four different nucleotides.
RNA is double-stranded; DNA is single-stranded.
DNA contains thymine; RNA contains uracil.
In DNA, adenine pairs with guanine; in RNA, adenine pairs with thymine.
Like DNA, RNA is made up of nucleotides. There are two differences that distinguish DNA from RNA: (a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom), and (b) RNA has the nucleobase uracil while DNA contains thymine.
1. Which of the following occurrence can be explain
by convection?
A. How a fire place can heat up people in a room
B. How the heat of the sun reaches earth
C. Why a handle of a metal spoon also gets hot when
placed on a steamy soup
D. Why chilly air always remains near the floor
2. Which of the following is NOT true about heat?
A. It is a form of energy
B. It transfers from one object to another.
C. It is caused by a temperature difference between
two objects
D. It determines the hotness or coldness of an object
3. Which of the following describes heat?
A. Energy stored in all objects regardless of
temperature
B. Energy that causes objects to have temperature.
C. Energy transferred due to difference in materials
D. Energy transferred due to temperature differences
4. An unknown object is placed in contact with a heat
source. It was observed that the object did not increase
its temperature Which of the following explains why?
A. The object is heated too much.
B. The object is heated via radiation.
C. The object is a thermal insulator,
D. The object is a thermal conductor.
Answer:
1. C. Why a handle of a metal spoon also gets hot when placed on a steamy soup.
2. D. It determines the hotness or coldness of an object.
3. D. Energy transferred due to temperature differences.
4. C. The object is a thermal insulator.
Explanation:
Convection is the transfer of heat energy through the movement of a liquid or gas from one place to another. If we place a metal object at a distance from the hot body so the fumes that comes out increase the temperature of the metal that is present on the hot body. Temperature determines the hotness or coldness of an object not the heat. The heat energy transferred from one body to another due to difference in temperature of both objects. Insulator are those materials which no ability to transfer heat energy from one place to another.

Answer: That answer is completely FALSE
Explanation:
In general, do organisms that have more traits in common also share more genes?
Answer:
In general, organisms that share similar physical features and genomes tend to be more closely related than those that do not. Such features that overlap both morphologically (in form) and genetically are referred to as homologous structures; they stem from developmental similarities that are based on evolution.

3. Most of the traits expressed in a person's phenotype are determined by Is
Most of the traits expressed in a person's phenotype are determined by is Phenotype.
What is Phenotype?Phenotype refers to an individual’s observable traits, such as height, eye color and blood type. A person’s phenotype is determined by both their genomic makeup (genotype) and environmental factors.
An observable characteristic is simply referred to as a "phenotype." Pheno, which has the same root as the term "phenomenon," simply means "observe."
It can therefore refer to anything from a common attribute, like height or hair color, to the presence or absence of a disease. It is also an observable type of an organism.
Therefore, Most of the traits expressed in a person's phenotype are determined by is Phenotype.

Why is a sea otter a “keystone”??
Explanation:
Sea otters are an iconic species, representing the beauty and diversity of marine life found along California’s coastline. They’re also considered a keystone species because of their critical importance to the health and stability of the nearshore marine ecosystem. They eat sea urchins and other invertebrates that graze on giant kelp.

Explain the relationship between mutations, adaptations,
natural selection, and extinction.
Answer: A mutation results in different alleles for a gene and these different alleles will cause adaptations that may be favorable or unfavorable. If no species in an area has adaptations suited for the environment after it changes, extinction will occur.Adaptations result from random mutations in the genes of organisms. Depending on the environment, these adaptations may be favorable or unfavorable. If an adaptation is favorable, it is selected by nature and, over time, more and more organisms in a population will have it. If the environment changes so much that the adaptations of a species are no longer enough for the species to survive, extinction will occur.Mutations is very different because it results in different alleles for a gene.Adaptations is where an animals ADAPTS to an environment.Natural selection consists of overproduction,variation, favorable adaptations.extinction is when a species completely disintegrates.
