Answer:
Explanation:The potential energy is converted to kinetic energy in the process. But I see no transfer of energy between the earth and the body.
And how does energy transfer takes place in case of negative work ? When a body is moved across a surface which has friction, the friction does negative work. Does it mean that a sort of energy transfer occurs between the surface (source) and the body (object
What diagram demonstrates how crossing-over contributes to genetic variety during meiosis?
Answer:c
Explanation:trust me
The diagram that demonstrates how crossing-over contributes to genetic variety during meiosis is diagram C.
Crossing over refers to the recombination or interchange of genetic material. This process (crossing over) occurs between non-sister chromatids during meiosis.Crossing over specifically occurs in the prophase I of meiosis.In conclusion, the diagram that demonstrates how crossing-over contributes to genetic variety during meiosis is diagram C.

Does the amount energy from food eaten by each organism equal the amount of energy used but each organism?
Answer:
Ecosystem follows the 10% law.
Explanation:
The amount of energy that is available in the ecosystem is equal and same is equally distributed. Plants use solar energy and convert it into usable energy for processing food and water in tissues and reproduction and root development. Later on when the plant dies or is eaten up the dead organic matter is converted to energy that is derived by the herbivorous or primary consumer. When then (90%) lost through respiration and digestion, waste generation in the body. After which the energy left may be again taken up by some secondary consumer and only 10% energy remains while the rest is diffused in the ecosystem and environment. Thus energy is neither created nor destroyed but transformed in its form.HELP!!! I WILL GIVE BRAINLIEST!!!

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.

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 a ship sinks in the middle of the ocean and it has a cargo of 28,000 rubber ducks. Instead of the ducks staying where the boat sunk at, the rubber ducks began to find their way to different coastlines as shown in the picture below. What do you think is causing the ducks to move in this pattern?
Answer:
Currents moving the ducks with them.
Answer:
Kind of Know
Explanation:
Tectonic plates shift all of the time, thats why we have oceans where we have oceans. So, the rubber ducks moed along the ocean patterns based off of the tetonic plates. I am pretty sure, hope this helps :).
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.

which phase do chromatids divide and cell contents begin to be divided?
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.

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.

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

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.

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.
