Explanation:
(d) State the importance of mitosis in the growth of a multicellular organism, such
as a
flowering plant or a mammal.
Explanation:
Like other multicellular organisms, plants grow through a combination of cell growth and cell division. Cell growth increases cell size, while cell division (mitosis) increases the number of cells. As plant cells grow, they also become specialized into different cell types through cellular differentiation.

Explanation:
Generation Number of purple flowers Number of white flowers 1 705 224 2 792 189 3 834 102 4 889 84 5 938 21 6 952 0 Ralph wanted to breed a pea plant that produced only purple flowers. He continued to breed purple-flower producing pea plants together over six generations. The results of Ralph's artificial selection are shown above. What did artificial selection do to the population of pea plants? A. caused a new species of pea plant to form B. increased its genetic diversity C. decreased its genetic diversity D. caused a pea plant to exhibit a new characteristic
Answer:
C
Explanation:
The correct answer would be that artificial selection decreased the genetic diversity of the pea plant.
Genetic diversity is a measure of the number of traits or characters.
Initially, the breeding produced a considerable population of both white and purple flower offspring. But as time goes on, the population of purple flower offspring increased while that of the white flower decreased till it eventually reached zero.
Thus, artificial breeding reduced the number of traits in the population of the offspring from two to one - a case of reduction in genetic diversity.
The correct option is C.

what are cork tissues? how are they formed?
Answer:
Cork is a protective tissue that separates the living cells of the plant from the outside environment. The formation of cork in the periderm is the result of the activity of a secondary meristem, the cork cambium, or phellogen.

Which of the following is true about moss sporophytes?
a. Sporophytes perform photosynthesis. C. Sporophyttes contain a single spore.
b. Sporophytes depend on the gametophyte for d. Sporophytes are very large.
nutrients.
Answer: sporophytes photosynthesise, particularly when immature, but depend on gametophytes for at least 50% of nutrient requirements
Explanation: In mosses, the gametophyte generation is the dominant generation unlike in higher plants. The diploid sporophyte generation produces several spores per capsule.

Explanation:
How might volcanic eruptions change the flow of energy on earth?
Answer:
It causes global warming due to emission of carbondioxide gas.
Explanation:
Volcanic eruptions change the flow of energy on earth by emitting gases such as carbondioxide and sulfur dioxide gases. Volcanic gases like sulfur dioxide is responsible for global cooling by reflecting solar radiation back to the space, while on the other hand, carbon dioxide emitted from volcanoes, has the ability to promote global warming by blocking solar radiation. If the amount of carbondioxide gas is higher as compared to sulfur dioxide gas so global warming occurs.

A helpful shortcut our brain makes in scene recognition is to assume that lighting comes from:
Answer: A. Above
Explanation:
Scientists believe that in order for humans to see things, the brain has to make certain assumptions which are done based on previous scenes that it has interpreted before because the eyes do not provide it with complete data. .
One of those assumptions is that light comes from above which is why the shape of a picture can change depending on the lighting in it.

List and explain the 3 paths natural selection can take.
Answer:
1. Stabilizing Selection
2. Directional Selection
3. Disruptive Selection
Explanation:
Stabilizing Selection
This type of natural selection occurs when there are selective pressures working against two extremes of a trait and therefore the intermediate or “middle” trait is selected for. If we look at a distribution of traits in the population, it is noticeable that a standard distribution is followed:
Example: For a plant, the plants that are very tall are exposed to more wind and are at risk of being blown over. The plants that are very short fail to get enough sunlight to prosper. Therefore, the plants that are a middle height between the two get both enough sunlight and protection from the wind.
Directional Selection
This type of natural selection occurs when selective pressures are working in favour of one extreme of a trait. Therefore when looking at a distribution of traits in a population, a graph tends to lean more to one side:
Example: Giraffes with the longest necks are able to reach more leaves to each. Selective pressures will work in the advantage of the longer neck giraffes and therefore the distribution of the trait within the population will shift towards the longer neck trait.
Disruptive Selection
This type of natural selection occurs when selective pressures are working in favour of the two extremes and against the intermediate trait. This type of selection is not as common. When looking at a trait distribution, there are two higher peaks on both ends with a minimum in the middle as such:
Example: An area that has black, white and grey bunnies contains both black and white rocks. Both the traits for white and black will be favored by natural selection since they both prove useful for camouflage. The intermediate trait of grey does not prove as useful and therefore selective pressures act against the trait.

How will water volume, incline gradient, and temperature affect the energy
of a stream?
Answer: Water Volume: The volume of water(discharge) in a stream affects the energy(velocity) of that stream. As the volume of the water in the stream increases, the velocity increases. ... Incline gradient: The incline gradient is also known as the slope of the stream.
