Explain how photosynthesis provides energy for consumers.
Blababa [14]

Answer:

Through photosynthesis, certain organisms convert solar energy (sunlight) into chemical energy, which is then used to build carbohydrate molecules. The energy used to hold these molecules together is released when an organism breaks down food. Cells then use this energy to perform work, such as cellular respiration.

A confined aquifer is _____. found in the unsaturated zone found between two impermeable layers the top layer of the saturated z
stealth61 [152]
The answer is

<span>Aquifers are underground layers of rocks which contain water and serve as important sources of freshwater. They are located below the water table and in the saturated zone. If an aquifer becomes trapped between two impermeable layer (for example, one below and one above that overlies the aquifer), the pressure act on the aquifer and it can become a confined aquifer.</span>

The phase of cell division in which chromatin condenses into chromosomes is ____ A. anaphase B. metaphase C. prophase D. telopha
Lady_Fox [76]

Answer:

C (Prophase)

Explanation:

All cells undergo division in order to produce more daughter cells. Cell division occurs immediately after the interphase, which is a resting and preparatory phase for mitosis or cell division. Prior to cell division, the DNA is found to be coiled around histone proteins to form a structure called CHROMATIN. The process of cell division occurs in four phases; Prophase, Metaphase, Anaphase, and Telophase.

In the Prophase stage, which is the first stage of mitosis, this Chromatin begins to condense or becomes compact by undergoing further coiling into a visible X-shaped structure called CHROMOSOME. This shape of the chromosome is as a result of the replication into sister chromatids that occurred in the S-phase of interphase.

A pure breeding tall pea plant was crossed to dwarf plant. What will be frequency of dwarf plants in F2?
Temka [501]

Tall pea plant was crossed to dwarf plant. The frequency of dwarf plants in F2 will be 0%.

  • A true breeding pea plant is one that, after self-fertilization, only bears offspring with the same traits.
  • True breeding organisms are those that share the same genes for the desired traits and are genetically comparable.
  • These animals possess homozygous alleles. If the alleles are distinct, only one of the gene's alleles—referred to as the dominant gene—will be expressed.
  • The other allele, referred to as the recessive one, has no effect.

According to the given cross:

                                  TT  X  tt   (parents)

                                 Tt Tt Tt Tt  (offspring) all tall

Hence the percentage of dwarf individuals is 0.

Simone is creating a model to track the movement of carbon atoms in an ecosystem. Which statement best explains the role of plan
Mademuasel [1]

Although I cannot see the model for Simone's experiment, I can offer the insight that the most likely role of plants in the model is that they consume the carbon atoms and produce oxygen.

<h3>How do plants affect the carbon in the atmosphere?</h3>
  • Plants are known to have a<u> great effect</u> on the carbon levels of the atmosphere.
  • The correlation is that the more plants are present, the less carbon is free in the air.
  • The reason for this is that plants use carbon dioxide as a substrate to manage the process of photosynthesis.
  • As a by-product, after consuming carbon dioxide and completing photosynthesis, plants release oxygen into the atmosphere.

Therefore, we can confirm that the most likely role of plants in the model created by Simone, is that they will consume carbon atoms in the form of carbon dioxide in order to sustain photosynthesis, which releases oxygen.
