Which of the following explains why meiosis contributes to genetic variations?
A - it increases the ratio of mitosis within an organism
B - It produces offspring that are different from either parent
C - It decreases the rate of mutation occurrence
D - It forms DNA that is resistant to environmental changes
Answer:
A
Explanation:
The reason of why meiosis contributes to genetic variations is because of option A. it increases the ratio of mitosis within an organism.
Why does meiosis contributes to genetic variations?Since the recombination and the non-dependent assortment in meiosis, each gamete comprise the different DNA set. It generated the unique combination of genes that should lead to zygote.
Also, it rises the mitosis ratio within an organism
Hence, the option A is correct.

boundaries.
B
Scientists are unable to map out the location of tec-
tonic plate boundaries.
С
Scientists can use satellite imagery to see tectonic plate
boundaries.
D
Scientists track where earthquakes have occurred most
frequently throughout history.

In this investigation, you will plot the locations of earthquakes and determine the boundaries of the earth's plates
Scientists are unable to map out the location of tectonic plate boundaries. So, the correct option is B.
What are Tectonic plates?A tectonic plate also known as a lithospheric plate is defined as a massive, irregularly shaped slab of solid rock that is composed of both continental and oceanic lithosphere. Plate size can vary from a few hundred to thousands of kilometers
By plotting the locations of earthquakes, scientists have not only been able to locate plate boundaries but they have also been able to determine plate characteristics and predict the motion of the plates. In this investigation we will plan the locations of earthquakes and determine the boundaries of the Earth's plates.
Thus, scientists are unable to map out the location of tectonic plate boundaries. So, the correct option is B.

Quail use feathers for thermoregulation, flight and camouflage. What type of adaptation are feathers?
A. Structural
B. Behavioral
C. Physiology
D. Feathers are not an adaptation
Answer:
structural
Explanation:
In addition to flight and body feathers, birds also have down feathers. Down feathers are soft and fluffy because they don't have barbules and barbicels (the structures that hook feather barbs together). Down feathers help to keep a bird warm by trapping air close to the body, which insulates the bird from the cold.

Which of the following facts implies that humans and fish had a common ancestor? A. Both species have the ability to swim. B. Both species must expel waste materials. C. Both species have gill slits when they are embryos. D. Both species are consumers.
Answer:
A common ancestor of humans and fish denotes the most recent organism, from which both the humans and fish have been evolved. Humans and fishes are vertebrates, which possess spinal column or backbone. Along with this, human embryos also go through a stage, during which they have gill-slits like structures in their neck as present in fish embryos.
These structures do not found in mature humans like fishes, but they support the fact that the humans share a common ancestral organism with fish.
the correct answer is option D). both species have gill slits when they are embryos.
Answer:
D= Both species are consumers.

What do you mean by meiosis?Meiosis is a special type of cell division of germ cells in sexually-reproducing organisms that produces the gametes, such as sperm or egg cells. It involves two rounds of division that ultimately result in four cells with only one copy of each chromosome.
The purpose of meiosis is to produce gametes, the sperm and eggs, with half of the genetic complement of the parent cells. In the figures below, pink represents a genetic contribution from mom and blue represents a genetic contribution from dad.
Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. These cells are our sex cells – sperm in males, eggs in females.

Mendel studied seven traits in pea plants. One of the monohybrid crosses he made was between plants with round seeds and plants with wrinkled seeds.
What was a conclusion Mendel drew from the F1 generation of this cross?
Explanation:
Traits are inherited in discrete units, and are not the results of "blending." ... traits can be dominant or recessive, and the recessive traits were obscured by the dominant ones in the F1.
Answer:
The dominant factor, or allele, is for round seeds.
Explanation:
The factors (or alleles) don't disappear when two species are crossed, so "the factors or alleles for round seeds disappear completely from the plants" and "the factors or alleles for wrinkled seeds disappear completely from the plants" are both incorrect. From the drawing, we can see that the F1 generation is a round seed, meaning the dominant factor is for round seeds. Hope this helps!

Suppose that this population of mice has stabilized so that both white and brown appear. White mice survive better in the winter and brown mice survive better in the warmer months. If a group of these mice migrated to an area that didn't get snowy in the winter, what do you think would be the long term effect on the color of these mice? Explain why.
Answer:
The population of the white mice would significantly decrease, and most of the mouse population would be with brown fur.
Explanation:
As stated in the question, the brown mice survive better in warmer times. This is due to the fact that with winter and snowy times it makes it harder for prey to spot the WHITE mice v.s. the BROWN mice who would very easily be spotted by the prey in snowy regions.

Answer:
anaphase stage
Explanation:
All of the chromatids are split in sync as the cell enters the anaphase stage. It is to be mentioned that the genetic material from prophase was called the chromatids not chromosomes (if you haven’t noticed it by now). However, since the sister chromatids are split in anaphase the genetic material is once again referred to as chromosomes.

22. What is a beneficial way ethylene affects plants; what is a negative way ?
Answer:
Beneficial is fruit ripening
And negative is abscission.
Explanation:
Ethylene is a plant growth regulator or phytohormone of plant. It is beneficial to plants in that it aid fruit ripening, it hasten flower opening and shedding of leaves.
Ethylene also have a negative effect and they include; Ethylene effects include: it result in loss of chlorophyll, abortion of major plants part, it lead to the stem shortening, abscission or dropping of plant parts, epinasty, and dormancy and scinence. Thus hormone can be produced when plants are injured, either mechanically or are affect by certain disease

Show your knowledge of photosynthesis by choosing the correct role of sunlight in the photosynthesis reaction.
Answer:
The sunlight's energy to change water and carbon dioxide into sugar glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch.
The process through which green plants produce their food is called photosynthesis. Photosynthesis requires light, which chlorophyll absorbs.
What is Photosynthesis?During photosynthesis, oxygen and glucose are created as byproducts when carbon dioxide and water mix in the presence of solar light energy.
Plants use their leaves to capture light energy during photosynthesis. Water and carbon dioxide are converted by plants into a sugar called glucose using the power of the sun. Plants use glucose as a source of energy and to create other compounds like cellulose and starch.
According to the claims made, chlorophyll does not mix with water. The pigment chlorophyll in plants merely absorbs solar light energy, which is required for the process of photosynthesis.
Therefore, photosynthesis requires light, which chlorophyll absorbs.
