If no energy is transferred, how much work is done?

Answers

Answer 1

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

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?

Answers

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!

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

Answers

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.

Does the amount energy from food eaten by each organism equal the amount of energy used but each organism?

Answers

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.

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

Answers

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.

Show your knowledge of photosynthesis by choosing the correct role of sunlight in the photosynthesis reaction.

Answers

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.

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.

Answers

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.

They made a difference in peoples lives and learned some important life lessons in the process. Organizations, including schools, are actively promoting service for all citizens as a way to be involved, help others, and improve themselves. Service is helping other people and being active in your community. For example, one group of teens planted a community garden with their friends. They grow a variety of vegetables. The garden requires regular care. The teens donate the produce to a local soup kitchen. Workers there use the produce to help feed people in the community. By tending the garden and donating their produce, the teens are actively helping make life a bit better for others in their community. Service is valuable in ways that cannot be measured in dollars. People volunteer or serve others without expecting money or gifts in return. Service is not about earning money. It is not just collecting money to give to a group. It is about action and contributing to the common good. The people who serve as well as those who receive help benefit in many ways that are more important than money or gifts. For example, a soup kitchen provides essential food to people who may otherwise go hungry. The soup kitchen is extremely valuable for those struggling to get enough to eat. Those serving learn about compassion and how helping others can improve life for all. Millions of Americans are making society better for themselves and for others.
