Why is it important to know the average mutation rate when using DNA comparisons to determine
how long ago lineages split?
Answer:
mutation rates can be used to design molecular clocks in order to estimate divergence times among species
Explanation:
In evolutionary biology, the substitution rates (also known as mutation rates) are used for the development of 'molecular clocks' which allow estimating the divergence times among species or among taxonomic groups. Molecular clocks can be designed by estimating the divergence rate of nucleotide sequences (either DNA or RNA) and amino acid (protein) sequences. These substitution rates can also be used to track how quickly viruses evolve (for example, in a pandemic situation).
List the four steps of mitosis in order. Describe what is happening during each phase.
Answer:
The four stages of mitosis are known as prophase, metaphase, anaphase, telophase. Additionally, we'll mention three other intermediary stages (interphase, prometaphase, and cytokinesis) that play a role in mitosis. During the four phases of mitosis, nuclear division occurs in order for one cell to split into two.

Explanation:
What is the process called when two glucose molecules bond together to form a
disaccharide and why is it important.
Answer:
Dehydration reaction (a condensation reaction)disaccharide will provide energy for chemical reactions in the body to take place.
Explanation:
The Condensation Reaction is an organic reaction in which two molecules combine to give a single product accompanied by the formation of a molecule of water H2O. Disaccharides are produced when two monosaccharides are chemically combined. The bond called O-glycosidic, is the bond by which monosaccharides join to form disaccharides or polysaccharides. In this type of bond, an OH group of an anomeric carbon of a monosaccharide reacts with an OH group of another monosaccharide, releasing a water molecule.The main function of disaccharides is to provide energy to the cells of the human body, or glycogen. This is achieved through enzymes that act in the synthesis of the disaccharide, extracting glucose. Among the main and best known enzymes that act in this process are insulin for sucrose, lactase for lactose, and trehalase for trehalose.

The golden-cheeked warbler and the black-throated green warbler look nearly identical to each other. What type of information could be used to determine if the birds are separate species? Select all that apply. The birds breed with each other where their territories overlap. The birds breed with each other where their territories overlap. The birds show differences in mating songs and behaviors. The birds show differences in mating songs and behaviors. The birds do not breed with each other where their territories overlap. The birds do not breed with each other where their territories overlap. The birds compete for food and nesting sites. The birds compete for food and nesting sites.
Answer:
The birds do not breed with each other where their territories overlap.
Explanation:
The correct answer would be that the birds do not breed with each other where their territories overlap.
A species consists of organisms that are phenotypically similar and are capable of mating to produce fertile progeny.
Hence, the first thing to establish that two organisms are not of the same species is the inability to breed with each other. If an eventuality occurs and they are able to breed, the resulting progeny would be invalid.
Therefore the fact that the golden-cheeked warbler and the black-throated green warbler do not breed with each other where their territories overlap is enough information to determine that the birds are separate species.
how does cell division help in growth and development of somatic cells and in gamete formation?
════════ ∘◦❁◦∘ ════════
[tex] \mathbb{CELL\:DIVISION\:(MITOSIS)} [/tex]
════════════════════
Well, im not sure what somatic cell is. But, the reason why cell division help in growth and development is because the main goal of cell division is to make more cells right? This is also why we keep growing (like taller/bigger) because more cells in our body because of that cell division.
#see pic of how cells in our body divide during mitosis
#sorry i borrow this ans for my latex experiment :v
════════════════════
Mitosis occurs in somatic cells this means that it takes place in all types of cells that are not involved in the production of gametes. Prior to each mitotic division, a copy of every chromosome is created; thus, following division, a complete set of chromosomes is found in the nucleus of each new cell.

A family business had bred dogs for over 250 years. During this time, 125 generations of dogs were bred for a single trait: protective instincts. Immediately after
birth, the puppies are sorted based on whether or not they have a white patch of fur on their chests. Those without this trait, are no longer bred for their
business and instead are adopted to pet stores and not private sales for people requesting the desired trait of protective instincts.
How could the breeders know these other dogs will not have the traits they are looking for when they are just new-born puppies?
Answer:
They can know if the trait has been carried on by looking at the bred dogs that have the trait and determining if the trait has been passed down by similar characteristics between the parent with the trait and the puppy that could have the trait.

The lineage of pea plants produced round seeds for four generations. The plants that fertilized these pea plants also produced round seeds. However, in the fifth generation, the plant produced to two plants with wrinkled seeds. Can that be possible? Explain your answer using your pedigree chart.
Answer:
Explanation:
This happened because two fully recessive plants where introduced into the lineage. these plants where paired with the dominate verison. this would make all of the offspring have the two traits. this being said it would make it possible for the offspring to be Wrinkled Seeds.
When two heter0zyg0us individuals are crossed -simple d0minant inheritance-, or a heter0zyg0us individual is crossed with a h0m0zyg0us recessive one, they can produce h0m0zyg0us recessive subjects among the progeny. Heter0zyg0us individuals among the fourth generation got crossed with another plant (h0m0zyg0us recessive or heter0zyg0us) and produced two h0m0zyg0us recessive plants expressing wrinkle seeds.
---------------------------
The first step is to understand the given information. So,
The first four generations produced round seedsPlants that fertilized these plants also produced round seeds (see generation II) Among the fifth generation there are two plants with wrinkled seedsLet us assume that a diallelic gene determines the shape of seeds.
D0minant allele R codes for round seedsRecessive allele r codes for wrinkle seedsNow, let us analyze the pedigree. According to the information provided here, we can tell that
black figures represent h0m0zyg0us d0minant individuals, grey figures represent heter0zyg0us individualsempty figures represent h0m0zyg0us recessive individualsRemember that Generations are represented with roman numbers.
We will name the plants with numbers from 1 to 26.
According to the information in the statement and the information in the pedigree, we can say that grey individuals from the fourth generation are heter0zyg0us expressing round seeds. They can produce wrinkle seeds, if they are fertilized by another heter0zyg0us plant or a h0m0zygous recessive one.
Option 1:
Two heter0zyg0us plants are crossed, and their offspring have wrinkled seeds.
Option 2:
One heter0zyg0us plant is crossed with a h0m0zyg0us recessive one, and their offspring have wrinkled seeds. Let us see the cross

What epigenetic marker changes cause chromatin to open up?
Answer Several lifestyle factors have been identified that might modify epigenetic patterns, such as diet, obesity, physical activity, tobacco smoking, alcohol consumption, environmental pollutants, psychological stress, and working on night shifts.:changes to the histone tails act indirectly on the DNA. For example, lysine acetylation may create a binding site for chromatin-modifying enzymes (or transcription machinery as well). This chromatin remodeler can then cause changes to the state of the chromatin. hope this helps ❤️❤️❤️
Explanation:
The changes with respect to the epigenetic marker should result to the chromatin at the time of opening up because When transcription factors could access the DNA binding sites.
Reasons of chromatin:It is the material that comprises of the chromosome that involved the DNA and protein. The major protein is called as the histones. It should be acted as the packaging elements with respect to the DNA.
Therefore, The changes with respect to the epigenetic marker should result to the chromatin at the time of opening up because When transcription factors could access the DNA binding sites and the gene expression is not be blocked.

Rearrange the steps of a tsunami formation in the correct order
1. two tectonic plates slide past each other underwater, causing a large movement of water
2. large ocean waves form
3. large ocean waves move in all directions away from the shifting plates
4. large ocean waves slow down and increase in height as they reach the coast
Answer:
two tectonic plates slide past each other underwater, causing a large movement of water large ocean waves form .large ocean waves move in all directions away from the shifting plates .large ocean waves slow down and increase in height as they reach the coastExplanation:
Tsunamis are initiated underwater and usually happen as a result of underwater earthquakes which can be initiated when tectonic plates slide past each other.
This causes a large movement of water such that large waves form and move away in al directions from the source. As these waves approach the shore they slow down speed but this only increases their height such that when they make landfall the effect could be devastating.
