Answer:
B
Explanation:
Mutations are a way different option from the original genomes, a mutation is a change within the genes and can mostly lead to the death of organisms. But only MOST of them lead to death which is why B is correct.
In an experiment, a snail was observed to have moved a distance of 0.5 meters in 2 hours. What rate of movement was observed in this experiment?
The rate of movement was observed in this experiment as 0.25 m/ hour.
How, explain your answer?A rate of movement is essentially a speed measurement, where you divide the distance crossed from point A to point B by the time it took to do it.
o, we know the snail moved a total distance of 0.5 meters. that's our distance crossed.
We know that took 2 hours. so we just have to calculate that:
0.5 meters / 2 hours = 0.25 m/hour
Thus, The rate of movement was observed in this experiment as 0.25 m/ hour.

Which of the following is the most important reason that a scientist should
replicate his or her experiments?
OA. To make sure that differences in the data are caused by real
differences and not by error
OB. To make sure that other scientists do not have to waste time
replicating this scientist's experiments
C. To practice the experimental procedures until the scientist is an
expert at performing them
D. To prove the scientist's hypothesis
Answer:
D. the only method of scientific investigation is in essence demonstrating the hypothesis is valid through repeated and more vigorous investigation using sound experimental techniques to produce the same or very similar results, ideally obtained from larger scale longitudinal studies, increasing sampling size and scale to lend greater and greater quality data on any query
A plant can have green (G) or yellow (g) leaves. It can also have a long (K) or
short (k) stem. A scientist is preparing a Punnett square for a dihybrid cross
of a plant with a genotype GgKk. What possible gametes can the plant
produce?
O A. GK, Gk, gk, gK
• B. GK, GG, KK, kK
• C. GK, Gk
O D. GK, gk
The possible gametes the plant can produce would be GK, Gk, gK, and gk. The correct option is A.
Gametes formationIn order to determine the possible gametes from the parent with the genotype GgKk, we need to cross the two traits in a monohybrid cross.
Thus: Gg x Kk
GK Gg gK gk
Thus, the possible gametes are GK, Gg, gK, and gk.

(40 points) Look at the diagram below. Which animals are most closely related? Which animals are least closely related? Explain your answer.
Answer:
The most closely related are amphibians and reptiles.
The least related are amphibians and mammals
Explanation:
Amphibians broke off from reptiles, birds, and mammals around 260 millions years ago and next up are the reptiles which broke off around 225 million years ago. So they are the most closely related
Mammals are the last to break off, around 200 million years ago. So they are the least related to amphibians.

A resident needs isolation precautions. Which will meet the person’s basic needs? Visiting the person as little as possible to prevent transmission Saying hello from the doorway Letting them know the scheduled for the activity room that day Getting out of the person’s room as quickly as possible
The person’s basic needs Visiting the person as little as possible to prevent transmission. Thus, option "A" is correct.
What can you do to help meet the psychosocial needs of a resident in transmission-based?Provide as much mental stimulation as possible by offering activities that the residents enjoy.
The people who are ensuring transmission-based precautions are required to feel mental peace. Mental anxiety, fear of infection, and stress can be some of the reasons for mental disturbances.
For such people, mental stimulation is necessary by allowing them to participate in recreational activities like fun indoor games.
Such activities will divert their mind from all the reasons for mental anxiety and people will feel relaxed.
Thus, option "A" is correct.

1. What are the unique characteristics of the macromolecule subunit and macromolecule you explored?
2. Describe how the subunit you modelled chemically combines with other subunits to form a macromolecule.
3. What are the functions of the macromolecule you explored?
4. Summarize the relationship between the structure of your subunit and the function of the macromolecule it forms.
Answer:
1. Macromolecules are typically BIG molecules, and they truly are the building blocks of cells. Macromolecules are generally built by combining many single units, or monomers, into larger units, called polymers.
2.polymers which are long chains of subunits called monomers.
3.Gigantic molecules, called macromolecules, populate a cell and provide it with important functions for life. For example, macromolecules provide structural support, a source of stored fuel, the ability to store and retrieve genetic information, and the ability to speed biochemical reactions.
4.Polymers are macromolecules, but not all macromolecules are polymers. The main difference between a polymer and a macromolecule is that polymers contain repeating units that represent monomers whereas not all macromolecules have a monomer in their structure

Answer:
Energy from ATP
Explanation:
ATP, or adenosine triphosphate, is a chemical that transports energy within cells. It is the cell's primary source of energy, and it is produced via photophosphorylation (adding a phosphate group to a molecule using light energy), cellular respiration, and fermentation. ATP is used by all living organisms. It is employed in signal transduction pathways for cell communication and is integrated into deoxyribonucleic acid (DNA) during DNA synthesis, in addition to being an energy source.
Explain how isolation causes the making of new species?
