A mouse population that is originally white in color becoming darker in color after several generations is an example of natural selection.
What do you mean by natural selection?Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations.
Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways.

Compared to other routes of administration, ________ is the most complicated way for a drug to enter the bloodstream.
Answer: the answer is oral consumption
Compared to other routes of administration, oral consumption is the most complicated way for a drug to enter the bloodstream.
How many ways can drugs enter the bloodstream?Substances can enter the body in different ways. Drugs can be smoked, inhaled, injected, swallowed (tablets, capsules, liquids), or applied transdermally (applied to the skin). Most of the drugs are taken orally and broken down in the gastrointestinal tract. Once the drug arrives, it is broken down by stomach acid before passing through the liver and into the bloodstream. Medicines can be taken in a variety of ways, including swallowing, inhaling, absorbing through the skin, and injecting. Each method has advantages and disadvantages, and not all methods can be used with all drugs. After the tablet is swallowed, it is usually absorbed through the stomach wall into the blood. These take effect within minutes, but usually take 1-2 hours to reach peak blood levels.To learn more about medication, refer

If you start off with 12 strands of chromatin how many strand of chromatin do you need to end up with in each cell after meiosis
Answer:
3
Explanation:
If you start off with 12 strands of chromatin how many strand of chromatin do you need to end up with in each cell after meiosis after 3 stages.
What is meiosis?
In sexually reproducing organisms, meiosis is a kind of cell division that results in a reduction in the number of chromosomes in gametes (the sex cells, or egg and sperm).
Body (or somatic) cells in humans are diploid, meaning they have two sets of chromosomes (one from each parent). The egg and sperm that combine during fertilization must be haploid, or having only one pair of chromosomes, in order to sustain this state.
Each diploid cell divides twice during meiosis to produce four haploid daughter cells, which are the gametes.
Nearly every human cell contains 46 chromosomes, 23 of which come from one of our parents and 23 highly similar chromosomes from the other parent. The appropriate number of chromosomes in a cell is crucial.
Therefore, If you start off with 12 strands of chromatin how many strand of chromatin do you need to end up with in each cell after meiosis after 3 stages.

Earth's high tides?
Answer:
The Moon
Explanation:
High tides and low tides are caused by the moon. The moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon. These bulges of water are high tides.

Which process does the grass used to make the food this horse needs?
A.) Photosynthesis
B.) Respiration
C.) Eating
D.) Digestion
Answer:
Photosynthesis
Explanation:
Just like trees and other plants, grass converts energy from sunlight into sugar through the process of photosynthesis. This energy is used to convert water and carbon dioxide into glucose. Carbon dioxide is absorbed through the stomata in the leaf and water is mainly derived from uptake in the roots. Photosynthesis makes the grass green and healthy.

C o all new cells come from preexisting cells
do all living things are made of one or more cells
Answer:
A (if it is a multi-answer question) also B. Even also C.
Explanation:
C is definitely not the correct answer because germs and microbes are living things and are made of only 1 cell. The cell is also the smallest unit of life because it is called "the building blocks of life", so it has to be the smallest unit of life. Even C, because cells multiply using an existing cell, just like we humans reproduce. First, it duplicates all of its parts, or contents, including the DNA, then they split to create a new cell, (or if i'm incorrect, 2).

Explanation:
make me brainliest pls
Xylem and phloem are the types of tissues found in the vascular bundle of plants.
What is the vascular bundle of plants?
In animals, the bloodstream is used to transport nutrients throughout the body. This function is carried delivered via the vascular system, a network of tissues and fibers in plants.
The xylem and the phloem are the two primary tissue types that make up the vascular system. Water and dissolved minerals are distributed upward through the plant through the xylem, first from roots to the leaves. Food is transported from the leaves to the roots through the phloem.
A mature woody stem or root's principal component is made up of xylem cells. They are arranged vertically in the heart of the plant, creating a column that transports water and minerals taken up by the roots up the stem and onto the leaves.
Transporting the food that the leaves have produced downward via the stem is a similar network of phloem cells that line the outside of the xylem.
Therefore, the xylem and phloem are present in the vascular system of plants.

The concentration of lactic acid in the student's
muscle tissue was most likely greatest during trial
A) A В) В
C) C D) D
Option D has the highest concentration of lactic acid in the student's muscle tissue.
We can arrive at this answer because:
Lactic acid increases its concentrations in the muscle due to a high physical effort in anaerobic conditions.This promotes a lack of oxygenation in the muscle, which through contractions, causes the cell to partially catabolize glucose molecules.The result of this is the creation of two pyruvic acid molecules, which will react with NADH2 molecules, creating lactic acid, which will build up in the muscle as the exercise continues.As we can see in the information presented above, option D shows the performance of flexions with more intensity and for a longer period, which justifies a greater accumulation of lactic acid in the muscle.
It is important to remember that the accumulation of lactic acid in the muscle is a negative situation and that it can cause muscle pain and fatigue.

Describe Hydrogen Bonding.
BEST ANSWER GETS BRAINLIEST
Hydrogen bonding is a interaction between two hydrogen atoms that is very essential for life on Earth. It is notoriously seen between water molecules, and it occurs when there is a slight disbalance in electrical charge between two Hydrogen atoms, and Oxygen atom that comprise water. This slight imbalance makes the Oxygen slightly more electronegative, and the two hydrogen atoms slightly more electropostive. The reason why water when spilled forms globules for this exact reasoning. The slightly positive charged hydrogen feels an electrostatic attraction to the Oxygen atom thus forming a strong bond. An interesting fact that comes from this electrical disbalance is that when salt is added to water, water is able to conduct electricity because of this disbalance in charge it can seperate the sodium chloride lattices into ions.
Human cells have 46 chromosomes. Each chromosome consists of a pair of identical chromatids attached together by a structure called a centromere. Once the chromosome has split, each chromatid is called a daughter chromosome. At the end of cytokinesis, how many daughter chromosomes will be found in each cell? Explain.
Answer:
92 daughter chromosomes.
Explanation:
There are 46 chromosomes in a normal cell and each chromosome turns into 2 daughter cells. So 46 plus 46 is 92.
