What does the slope of the curve on a distance vs time graph represent?
Answer:
What does the slope represent on a velocity graph? The slope of a velocity graph represents the acceleration of the object. So, the value of the slope at a particular time represents the acceleration of the object at that instant.

Essential Question: Compare and contrast the structure and function of the major organelles found in plant and animal cells.
Answer: Structurally, plant and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, lysosomes, and peroxisomes. Both also contain similar membranes, cytosol, and cytoskeletal elements.

Osmosis which is a form of passive transport
Answer:
represents the flow of water through its concentration gradient, through a semi-permeable membrane.
Explanation:
This means that water flows from where it is in a higher concentration to a place where it is in a lower concentration to try to equalize the concentrations of both solutions.
Osmosis is an example of diffusion when molecules tend to be evenly distributed in space.

What is the short definition of a plant cell?Plant cells are eukaryotic cells with a genuine nucleus and particular organelles to carry out particular tasks. Plant cells do, however, include several organelles that are unique from those seen in other eukaryotic cells.
Where can you find plant cells?Roots, stems, leaves, flowers, and reproductive structures are only a few of the major classes of cells and tissues that are formed when plant cells differentiate from undifferentiated meristematic cells, which are similar to the stem cells of animals.

A limiting factor is an environmental factor that increases the growth of population? True or False
Answer:
False
Explanation:
A limiting factor is the environmental factor that is of predominant importance in restricting the size of a population.
A limiting factor is an environmental factor that increases the growth of population-This statement is false.
Limiting factor:
In biology, the term restricting component is characterized as a natural element or variable that has the ability to limit the development, overflow, or appropriation of a populace in an environment. These elements are available in restricted supply. Subsequently, creatures will generally vie for their restricted accessibility in the environment.
Thus, Limiting factor does not increase the growth of the population.

One line with red flowers and the other line with violet flowers. You carry out a monohybrid cross and find that all of the F1 offspring have violet flowers, while 97 of 400 F2 offspring have red flowers.
Explain the inheritance of flower colour in this plant species.
Answer:
See the answer below
Explanation:
The inheritance of flower color in the plant species follows the simple dominance/recessive inheritance of Mendel. The red flower trait did not show up at all at F1 only for it to show up at F2. It simply means that the red flower trait is recessive while the violet flower color is dominant.
Assuming that the allele for violet flower color is designated as R while that of red flower color is designated as r. The genotype of the violet flower would be true-breeding, RR, while that of red flower color would also be true-breeding rr:
RR x rr
F1 Rr Rr Rr Rr
phenotype ratio = all violet flower color
Rr x Rr
F2 RR Rr Rr rr
phenotype ratio = 3/4 violet flower color and 1/4 red flower color
97 red flower offspring out of 400 is approximately 1/4.
Hence, the inheritance of flower color in the plant obeys a simple dominant/recessive Mendelian law with the violet color trait dominant over the red color trait.

a. dendrite.
b. axon.
c. cell body.
d. neuroglia.
Answer:
Dendrite
Explanation:
Dendrite with cell body are cytoplasmic projections that are present at the begin of neurons and help increase the cell body surface area through their extensions. The cytoplasm of dendrites and that of cell body have the same number of neurons. Dendrite receive electrical impulses from neurons and send those information to the sons.

Dihydromyricetin (DHM), a chemical found in the moyeam plant of Asia, has shown the ability to treat certain
cancers.
Which of the following answer choices best describes a possible mechanism of action for this cancer drug?
Choose 1 answer:
А
DHM decreases apoptosis in cancer cells.
DHM decreases apoptosis in normal cells.
DHM promotes apoptosis in cancer cells.
D
DHM promotes apoptosis in normal cells.
Answer:
(C) DHM promotes apoptosis in cancer cells.
Explanation:
Since some cancers are caused by a lack of apoptosis (programmed cell death), DHM treats cancer by forcing apoptosis to occur in cancer cells, stopping their growth and division.
The choice which best describes a possible mechanism of action for this cancer drug is DHM promotes apoptosis in cancer cells. The correct option is C.
What is Dihydromyricetin (DHM)?DHM is a chemical that is present in the plant, Hovenia Dulcis grow in Japan. It is a raisin plant and has several medicinal values. It is used in East Asia as a hangover medicine.
Apoptosis is a process of cell death, so if DHM promotes apoptosis in the cancerous cells, then it will reduce cancer by killing the cancer cells.
Thus, the correct option is C, DHM promotes apoptosis in cancer cells.

The Chatham Island robin is a small endangered bird found in scrub forests off the coast of New Zealand. The robin is preyed upon by introduced species such as cats and rats. In 1980, the population decreased to only 5 individuals and every individual today is a descendant of a single female. Which of the following is best illustrated in the decline of the Chatham Island robins?
1. Carrying capacity
2. Population bottleneck
3, Population overshoot
4. Type I survivorship
Answer: 2. Population bottleneck
Explanation:
A Population bottleneck is a term used to refer to an event that causes the population of a species to reduce in very large numbers. Such an event can be environmental disasters like famine, the overhunting of a species or the destruction of its habitat.
In the case of the Cha-tham Island Robin, the bottleneck event must have been the introduction of cats and rats which then went on to hunt the birds to near extinction.
