<span>The cells that are on each side of the stomatal pore and open and close
it like a mouth is called <u>guard cells</u>. Guard cells are found almost all
over the body part of the plant. The opening and closing of the stomata acts as
a mediator by changes in turgor pressure of the guard cells. Turgor pressure
pushes and sometimes out of the cell wall of the plant to allow ions of
solution to come in and out. The stomatal pore of the guard cell becomes large
when water is present around it and it is small when water is not present. </span>
The genotypes that indicates a homozygous dominant trait is : B. TT
Homozygous : both alleles must be the same, so it eliminate option A.
Dominant trait : One of the allele must be written in Capital letter, so it eliminate option C.
this leaves option B, as the answer
hope this helps
The process of photosynthesis is energy storing because the process converts light energy into the chemical energy which is stored in the bonds of glucose.
Option A
<h3><u>Explanation:</u></h3>
Photosynthesis is the process by which plants convert carbon dioxide and water into glucose and oxygen by means of chemical reaction in presence of sunlight. This reaction is the only source of food to each and every forms of heterotrophs which consume either a producer or another consumer to live.
This process utilizes the Sun's energy to deprotonate the water molecules and then store these protons in a place from which ATPs are produced by releasing the protons. Thus the energy produced is stored in form of ATPs, which are utilized to produce the glucose from carbon dioxide and water. Thus its an energy storing process which stores the Sun's heat and light energy into chemical energy of glucose.
1. Biogeography, the study of the geographic distribution of plants, animals, and other forms of life. It is concerned not only with habitation patterns but also with the factors responsible for variations in distribution.
2. weathering and other natural forces break down the substrate, rock, enough for the establishment of certain hearty plants and lichens with few soil requirements, known as pioneer species. These species help to further break down the mineral-rich lava into soil where other, less hardy species can grow and eventually replace the pioneer species. In addition, as these early species grow and die, they add to an ever-growing layer of decomposing organic material and contribute to soil formation. This process repeats multiple times during succession. At each stage, new species move into an area, often due to changes to the environment made by the preceding species, and may replace their predecessors. At some point, the community may reach a relatively stable state and stop changing in composition. However, it's unclear if there is always—or even usually—a stable endpoint to succession.
3. I don’t have the video so I’m going to take. Wild guess. Just look up types of finches
4. Broadly speaking, different species are unable to interbreed and produce healthy, fertile offspring due to barriers called mechanisms of reproductive isolation.
These barriers can be split into two categories based on when they act: prezygotic and postzygotic.

Answer:
TTAGCCATG
Explanation:
Deoxyribonucleic acid (DNA) is a double helix molecule made up of two complementary polynucleotide strands oriented antiparallel to each other. Each nucleotide in both DNA strands is composed of a five-carbon sugar (deoxyribose), a phosphate group and a nitrogenous base. In DNA, there are four types of nitrogenous bases: Thymine, Guanine, Adenine and Cytosine (in RNA, Uracil replace Thymine). According to the base-pairing rules, Adenine always pairs with Thymine through two hydrogen bonds, whereas Guanine always pairs with Cytosine through three hydrogen bonds.
