Answer:
There is a constant exchange of carbon from the abiotic and biotic environmental elements to the atmosphere. The breakdown of glucose is known as cellular respiration, and creates the byproduct carbon dioxide. This exhaled carbon dioxide is the method by which humans return carbon to the carbon cycle.
Explanation:
within a forest ecosystem, there is a large amount of diversity among members of a warbler species. of the following stages of meiosis illustrated for a typical cell, which contributes most to diversity among the warblers?
Crossing over occurs between homologous chromosomes, and is closely involved in genetic variation. The stage that most contributes to diversity is stage C, where you can see chromosomes after crossing-over.
----------------------------
There are different mechanisms involved in producing genetic variation among descendants. These are,
Crossing-over between homologous chromosomes (prophase 1), Random lining of homologous chromosomes (metaphase 1),Random fertilizationThe Crossing-over events occur between two homologous chromosomes in the equatorial plane and make the daughter cells genetically different from the original one.
The Chiasma is the position where two homologous chromatids interchange genetic information, giving a place for new genetic material or information to be provided to descendants.
After crossing over, homologous chromosomes get separated again.
In the attached imaged there are four different stages of meiosis.
Stage C is the one that contributes the most to diversity.
We can see that crossing over has already occurred between homologous chromosomes, and they have already interchanged segments.
In the image you will see the difference between chromosomes that has gone through the crossing over mechanism, and chromosomes that has not. The difference in color represents segments interchange and variation.

How does 02 enter the mitochondria
How does oxygen enter the mitochondrial matrix? The electrons taken from NADH and FADH are passed to several other proteins in the inner mitochondrial membrane. Ultimately, they are passed to oxygen (O2). O2 becomes two molecules of water (H2O) after receiving four electrons. This is how oxygen is used by cell respiration.

What three things might influence a slide when conditions are right? What types of material can make up a flow? (Site 1).
A slide can be influenced by friction, weight, and the angle of the slope. The materials that form flow generate less friction depending on the environmental conditions.
A slide is a movement that occurs when a fragment of soil/rock suddenly moves down a slope.
Slope stability is a factor influenced by the angle of the slope and the strength of the materials (e.g., rocks) on it.
The slide movement can ultimately be considered as a battle between friction versus gravity.

Describe the process of oxidation in terms of electrons AND energy.
Oxidation is described as the loss of electrons and energy by a molecule.
OXIDATION:Oxidation is a process whereby a molecule loses electrons (e-) or energy to become positively charged. Oxidation changes the oxidation number of the molecule involved depending on the number of electrons lost. Reduction is the opposite of oxidation, and it entails gain of electrons and energy by a molecule. Together, they are called oxidation-reduction or redox reaction.Learn more about oxidation at: https://brainly.com/question/3867774?referrer=searchResults
!!!!NEED HELP ASAP ILL GIVE BRAINLIEST AND 25 POINTS!!!!! How do proteins help transport of materials through the membrane?
Answer:
Channel proteins can aid in the facilitated diffusion of substances by forming a hydrophilic passage through the plasma membrane through which polar and charged substances can pass.
Explanation:
Answer: By forming a continuous protein pathway across the membrane, these proteins enable specific hydrophilic solutes to cross the membrane without coming into direct contact with the hydrophobic interior of the lipid bilayer. Carrier proteins and channel proteins are the two major classes of membrane transport proteins.

when talking about how water changes from liquid to gas and back to liquid
again
In a cloud, water droplets condense onto one another, causing the droplets to get bigger and increase. When these droplets heavy enough, they fall to Earth as rain droplets. That is when we feel and see the rain. Water vapor turns into clouds when it cools and then condenses,or when it turns back into liquid water or ice.

What process is the "copying" portion of protein synthesis? What is being copied? Why does it have to be copied?
The process of protein synthesis is known as translation. During this process, the mRNA is being copied into an orderly sequence of amino acids to produce a polypeptide.
During gene transcription, a fragment of DNA called gene is used as a template to generate a complementary messenger RNA (mRNA) sequence.
Afterward, this mRNA will be used as a template to create a protein by a process called translation.
The linear order of triplets of nucleotides or codons in mRNA will be used to add ordered amino acids to the growing polypeptide chain (i.e., the protein).

Mary wanted to know if seeds needed water to start growing or if any kind of liquid would work. Mary set up several experiments to find out. She used radish seeds, paper towels, plastic bags, and different kinds of liquid in her experiment. Mary put three seeds into each bag. She then used 30mL of liquid to wet a paper towel and put a different paper towel in each bag. Mary put all of the bags on the same table next to a window so that they could each get the same amount of light. She waited three days and then checked her plants.

dependent variable: how much the plants grow if at all.
control: they all received the same amount of light, that or the paper towels are the same.
experimental group: It's not stated that she did indeed use water, but there is a need for a control group, if so, then it's the other 2 groups that didn't use water, also because I can't think of anything else.
control group: The groups that used water rather than the other 2 plants.
