For diffusion to occur, which condition must be met?
A concentration gradient must exist.
A hypotonic external environment must exist.
A hypertonic external environment must exist.
Dynamic equilibrium must exist.
Answer:
A concentration gradient must exist.
Explanation:
For diffusion to occur, a concentration gradient must exist. Therefore, the correct option is A.
The movement of molecules along a concentration gradient is known as diffusion. It is a significant process that all living things go through. Diffusion facilitates the flow of materials into and out of cells.
Without the use of energy, molecules can be transported from an area of high concentration to an area of low concentration through the process of diffusion. Simple diffusion and Complex diffusion are the two types of diffusion. Diffusion was made easier.

What is the end product of the process of respiration? *
A. glucose and oxygen
B. water and carbon dioxide
Answer:
B. carbon dioxide and water
Explanation:
Respiration is a process that animals and plants undergo to create energy to grow, move and sustain life.
The equation for cellular respiration is:
glucose + oxygen —> ATP + carbon dioxide + water
The organisms use glucose from food and oxygen to create ATP (useable energy), carbon dioxide and water.
Therefore, the answer is B. Carbon dioxide and water. Glucose and oxygen are not the end results, they are used to make the end results.
Answer:
B. water and carbon dioxide

1 nasal cavity
2 lungs
3 red blood cells
4 cells of the body
Answer:
cells of the body
Explanation:
Respiration happens in the cells of plants, animals and humans, mainly inside mitochondria, which are located in a cell’s cytoplasm, energy released during respiration is used by plants to make amino acids, and by animals and humans to contract their muscles to let them move. Don't confuse respiration with breathing. Respiration releases energy, while breathing

The flowchart below shows the three generations of a cross between a pea plant that has yellow pods and a pea plant that has green pods. Yellow pods are the dominant trait. The flowchart is missing the labels that describe the traits. A flow chart is shown. A and B both go to C. C goes to both D and E.
Hello. This question is incomplete. Also, you forgot to show the flowchart. The flowchart is attached below and the full question is:
The flowchart below shows the three generations of a cross between a pea plant that has yellow pods and a pea plant that has green pods. Green pods are the dominant trait. The flowchart is missing the labels that describe the traits.
In which squares should the phrase “Green pods” appear?
1.A and D 2.B and E 3.A,C and D 4.A,B,C,D and E
Answer:
3.A,C and D
Explanation:
As shown in the question above, the flowchart shows the crossing of a pea plant with dominant features (green pods - AA) and a pea plant with recessive features (yellow features - aa). The crossing between plants with AA and aa alleles generates a completely Aa population, which in this case, has the dominant characteristic, that is, it has green pods. This is because the "Aa" alleles are called heterozygous and develop the dominant characteristic.
As we can see in the flowchart, the crossing between the two pea plants generated an offspring that is identified by table C, as we know this offspring has green pods and in the flowchart it is represented by a grayish rectangle. Therefore, we can say that the other gray rectangles represent pea plants with green pods, which are rectangles A, C and D.

Option are not provided in the question. The complete question is as following:
The cause of humanity's increased water consumption is an increased population. What is the effect?
A. less potable water, a growing threat to biodiversity
B. more potable water, a growing threat to biodiversity
C. less potable water, a decreased threat to biodiversity
D. more potable water, a decreased threat to biodiversity
Answer:
A. less potable water, a growing threat to biodiversity
Explanation:
The increasing population of human causes increase in water consumption that leads to reduction in portable water, which is a growing threat to biodiversity .
Portable water or freshwater is used for drinking by humans beings along with that it provide habitat to many diverse marine wildlife and they are important to local ecosystems as they provide sources of income and food to humans and other wildlife.
Freshwater or portable water play very important role to control flood and erosion.
So, decrease in portable water result into decrease in biodiversity.
Hence, the correct option is A. less potable water, a growing threat to biodiversity .
Mammals that live in the Arctic Ocean have a large amount of blubber, which is a fatty tissue just beneath the skin.
Which statement best relates why these animals have so much blubber?
O Lipids in blubber insulate the animals from cold water.
O Proteins in blubber help the animals move to stay warm.
O Carbohydrates in blubber provide all the energy that the animals need to stay warm.
O Nucleic acids help build the lipids in blubber, which keep animals warm by regulating cell activities.
Answer:
Lipids in blubber insulate the animals from cold water.
Explanation:
Lipids are fatty tissue, or fats in the cells. Blubber is fat. The fat helps insulate animals from cold water, especially in the Arctic known for being freezing. Fats can help maintain and keep body heat, hence why skinnier people are colder. Without lipids, they would most likely freeze.

In roses, red flowers and long stems are dominant traits. A rose plant that is homozygous for both red flowers and long stems is
crossed with a rose plant that is heterozygous for red flowers and homozygous for short stems. What percentage of the offspring
will exhibit red, long-stemmed flowers?
25 percent
O 50 percent
O 75 percent
O 100 percent
Answer:
This is late but the answer is 100%
Explanation:
I got a 100 on the test
The percentage of the offspring that will exhibit red, long-stemmed flowers is 100 percent; that is the last option as all of the offspring will show dominant traits, which are red, long-stemmed.
What is genetic crossing?In the context of genetics, traits are characteristics that are passed down from parents to offspring through their genetic material (DNA). These traits are determined by genes, which are segments of DNA that contain the instructions for the development of a particular characteristic. Here, the gene for flower color in roses has two alleles: R (red) and r (white). The R allele is dominant, and the r allele is recessive. Similarly, the gene for stem length has two alleles: L (long) and l (short). The L allele is dominant, the l allele is recessive, and from the cross, all will be dominant.
Hence, the percentage of the offspring that will exhibit red, long-stemmed flowers is 100 percent; that is the last option.

Which type of selection leads to increased phenotypic and genetic variation? directional selection disruptive selection stabilizing selection species selection
Answer:
diruptive selection/ diversifying selection
Explanation:
disruptive selection often leads to more variations in species
The circumstance that concludes whether the organism will be able to accommodate and endure in the changed conditions is called selection.
The correct answer is:
Option B. Disruptive selection.
This can be explained by:
Disruptive or diversifying adaptation occurs when there is a change in population genetics in which the traits are valued over intermediates.This type of assortment supports either the dominant or the recessive trait but do not favour intermediates.For example, in selection between tall, short or intermediate organisms the tall and short will be selected over the medium heightened organism.Therefore, disruptive selection will lead to increased phenotypic and genetic variation.
