Hello there, friend! A simple answer is below.
The answer is Guard Cell.
Explanation:
Guard cells are specialized plant cells that regulate gas exchange in the epidermis of leaves, stems, and other organs. They are generated in pairs, with a stomatal hole forming the space between them. When water is abundant and the guard cells are turgid, the stomatal holes are the biggest; when water is scarce and the guard cells become flaccid, the stomatal apertures close.
When investigating a crime scene to determine if a suspect is possibly guilty, police often collect DNA evidence from the scene, such as DNA round in hair. What can police do with this DNA evidence?
Answer:
the physical sample of Subject's DNA profile will be destroyed immediately, and in no circumstances held any longer than 30 days; any and all data about Subject's genetic profile derived from that physical sample will be deleted immediately, and in no circumstances held any longer than 30 days. they can use the DNA sample to identify a suspect or use it in a court of law.
Explanation:
Explain why cell contents and their environment are likely to freeze under extremely cold temperatures
Answer:
Explanation:
A fall in temperature can also adversely affect cell and cell membranes. At low temperatures, the phospholipids' fatty acid tails are moving less and stiffer. This reduces the membrane's overall fluidity as well as reduces its permeability and perhaps limits the entry into the cells of vital chemicals like oxygen and glucose. Also, low temperatures can impede cell development by preventing cell size expansion.
In severe cases, such long term exposure to sub-freezing temperatures, fluid in the cell can start solidifying and can form crystals that breach the membrane and destroy the cell.
What is an atom trying to do
when it combines with other
atoms?
A. produce a reaction Ting
B. change state of matter
C. become less stable
D. become stable
Answer:
D. become stable
Explanation:
Atoms like to be stable. The primary reason why atom combines with another atom is to get in a lower energy state. This is why octet rule (where atoms have 8 electrons in outer shell) or duet rule (where atoms need two electrons in their outermost shell) are so crucial because they allow atom to be in the lowest energy form.
An example has been included below:
When an atom is trying to bind with the other atom then it is trying to become stable that is they are trying to come in a stable state. Option D is the correct answer.
It is the gaseous atoms that bind together very fastly and they make the bonds quickly.
In an tom when it is a state of the atom where an atom in its single state is not that stable but when it reaches the correct bonding atom which can stable is electronic configuration and can make stable bonds are called to be in their stable state.
For example oxygen atom in its nascent state that is O state is very unstable and is very reactive in nature that is tryting to form the bonds such that the reactive nature of the atom gets resolved along with the stable state can be achieved.

Which statements best explain how students would know if a chemical reaction occurred during the steel wool demonstration? Select TWO correct answers from the choices below.
Answer:
When the heat energy releases and formation of iron oxide.
Explanation:
When the heat energy releases and formation of iron oxide are the indications that chemical reaction takes place. during the steel wool demonstration. During the steel wool demonstration, heat energy released when the iron combine with oxygen forming solid iron oxide. So we can conclude that release of heat energy and formation of iron oxide tells us that the chemical reaction takes place.

A mammal's red blood cells produce the protein hemoglobin, which carries oxygen through the bloodstream. Its hair follicle cells do not produce hemoglobin. Which statement is true about these differences? A) The red blood cells contain different genes than the hair follicle cells, causing the cells to differentiate B) The red blood cells contain DNA, but the hair follicle cells do not C) A red blood cell and hair follicle cell have the same genes, but they are expressed differently D) The hemoglobin is produced from recombinant DNA, which is only found in red blood cells
Answer:
C) A red blood cell and hair follicle cell have the same genes, but they are expressed differently
Explanation:
All cells of a living organism contain the same genetic sequence i.e. they contain the same set of genes, however, differences in the expression of these genes may occur. This is responsible for the different specific roles or functions played by organs of the body system.
The expression of a gene refers to the process by which a gene is transcribed and translated into a protein molecule, which is responsible for traits in the body. Genes are expressed differently in order for certain cells to function differently and specifically. For example, difference in expression of genes is responsible for the ability of red blood cells to produce hemoglobin and the inability of hair follicle cells to, even if they contain same genes.

What is water cycle?
The continual circulation of water on, above, and below the Earth's surface is referred to as the "water cycle," sometimes known as the "hydrologic cycle" or the "hydrological cycle."
The water cycle significantly affects the climate. For instance, a rise in temperature is a result of the greenhouse effect. The earth's temperature would rise sharply without the water cycle's evaporative cooling action. Other biogeochemical cycles also depend on the water cycle in one way or another. All organisms are affected by this cycle.

which statement best describes how nutrients enter the root cells of the onion plant
Answer:
2. hope helpful answer to your question
An onion's bulb is made of altered leaves. The chloroplast-containing onion's leaves undergo photosynthesis, but the little glucose that is generated during this process is turned into starch (starch granules) and stored in the bulb.
What route of nutrients enter the root cells of onion plant?Through root hairs near the very tip of the roots, the majority of nutrients are absorbed. Ultra-fine roots called root hairs have a vast surface area, which makes it possible for them to absorb more water.
Vegetable plants release moisture through their leaves, generating a vacuum that pulls nutrient-rich surface soil solution toward the plant roots.
The movement of the vast majority of plant nutrients (98%) from the soil to the root surface is explained by this mass flow process brought on by leaf transpiration.
Therefore, Most plants collaborate with various fungus to take up more nutrients from the water in the soil.
