Answer:
The energy in most ecosystems flows through the food chain. In physical ecosystems and most marine ecosystems, the energy flow starts in green plants that harvest some of the sun’s energy. The plants are then consumed by animals, bacteria, and other creatures, which are themselves eaten by other creatures. At each step in the food chain, energy is lost as heat.

The number in each circle below represents the chromosome
number of the cell. Which diagram represents the production of
offspring by an asexually reproducing organism?
Through mitosis a diploid somatic cell (2n) produces two daughter diploid cells (2n). The correct oprion is C. Diagram C represents the mitotic event.
As3xual reproduction occurs through mitotic events.
What is Mitosis?Mitosis is a process by which, from a diploid somatic cell (2n), two daughter diploid cells (2n) are produced.
First occurs duplication of the cell content, and then the separation into two new cells happens.
Mitosis occurs in only one phase.
In the prophase, it occurs chromosomes condensation and nuclear membrane breaks.During the metaphase, chromosomes are taken toward the center of the cell by the spindle apparatus. Once in the equatorial plane, chromosomes line up.Each chromatid joins with a microtubule of opposites poles.
In Anaphase, chromatid sisters separate. The bonds that were keeping them together break, and each of them migrate to the opposite poles.In telophase, duplicated chromosomes are already in the corresponding poles, and the nuclear membrane forms again in each pole. Finally, cytokinesis occurs.From the four diagrams, only diagram C represents a mitotic event.
A diploid cell (2n = 8) produce two daughter diploid cells (2n = 8). The whole process occurs in one phase.
The correct option is C.

How are metations and adaptations are related
Answer:
A mutation that occurs in body cells that are not passed along to subsequent generations is a somatic mutation. ... Alternately, if the mutation has a positive affect on the fitness of the offspring, it is called an adaptation. Thus, all mutations that affect the fitness of future generations are agents of evolution.

The United States is often called the "melting pot" because people from all nations have made a home here. If someone has a grandmother from Brazil, for example, that came to live in the US, would relocating to Chicago change her grandkids’ skin tone phenotype? Why or why not?
Answer:
Technically no
Explanation:
Technically no. The skin tone of the individual is caused by two factors, one is genetic and the other is environmental. The genetic factor will continue being there since the grandkids would be descendants of the grandmother. The environmental factor can change skin tone phenotype over the course of an individual's life. Although in this scenario, both locations have the same type of weather. Both Brazil and California are incredibly hot locations all year round.

An enzyme
Please help!!!
Answer:
Enzyme molecules are made up of one or more amino acid chains. The sequence of these chains is what specifies different enzymes. These long chains fold up into unique shapes which allows the enzyme to carry out chemical reactions, this varies based on the type of enzyme.
Enzymes speed up chemical reactions in the body that help keep us alive, for example, enzymes help with multiple things such as digestion, growth, healing, reproduction, etc.

The question would be properly written with options attached for the sake of comprehension:
Select the statement(s) that accurately illustrate scenarios of weathering.
A. Water flows into cracks in a rock, freezes, and expands, pushing against the crack making it wider.
B. Wind gusts carry large amounts of sand across the landscape creating a sandstorm.
C. Plant roots expand cracks in rocks as the plant grows.
D. Sand particles in the blowing wind may act like sandpaper to rub against the rocks and wear off small particles.
E. Oxygen in the air reacts with iron ore in a rock creating streaks of rust
The correct options in the question above are:
Options A, C, D, and E.
Explanation:
First, Weathering is the actions that lead to the gradual but continuous breakdown of rocks and minerals into soils. There are two main kinds of weathering: mechanical weathering and chemical weathering.
From the question above, options A, C, and D are all examples of mechanical weathering where rocks are broken down physically into smaller pieces.
Option B would have also been correct but didn't mention that the sandstorm brushed against the rock or collided with it.
While option E is an example of chemical weathering because of the chemical reaction between the oxygen in the air and the iron ore in rock. This results in the breakdown of minerals that are rich in iron forming new compounds creating rust.

Sustainable forestry: seeks to conserve forests for the long-term commercial harvest of timber and non-timber forest products by maintaining a mix of forest trees, by age and species, rather than imposing a monoculture. due to the complexity of goals, is most effective when it involves cooperation among environmentalists, loggers, farmers, indigenous peoples, and local, state, and federal governments. approaches vary from one forest ecosystem to another, in response to different environmental, cultural, and economic conditions. is all of the above.
Answer:
Yes, it is all of the above.
Explanation:
Yes, all the above statements are necessary for sustainable forestry because trees and other wild plants of the forest are necessary for all farmers, loggers, environmentalists, indigenous peoples and for the governments. The environmentalists study on these plants to find out the impact of these different plants on the environment, the farmers cultivate trees and plants to get money by selling it, the employment of loggers also related to these forests and the indigenous peoples also gain benefits by gaining food as well as medicines from it. This forest also fulfill the needs of wood and other products of the country.

Multiple organisms may be affected by the loss of a plant species
Explanation:
If a organisms food source were to vanish, it would affect the herbivores that feed on that plant, but also the carnivores/omnivores that feed on the herbivores. Because the herbivores will die as a result from not having food. This will also lead to the carnivores/omnivores to die.

Chlorophyll is a green pigment found in plants and other photosynthetic organisms, such as algae and some bacteria. It plays a critical role in photosynthesis, the process by which plants convert light energy into chemical energy to fuel their growth and development.
Chlorophyll is able to absorb light in the blue and red regions of the visible spectrum, while reflecting light in the green region, which gives plants their characteristic green color. T
his pigment is essential for capturing the energy from sunlight and converting it into chemical energy in the form of ATP, which is used to power the reactions that drive photosynthesis.
