Answer:
They work together to regulate water loss and gas exchange.
They work together to regulate the loss of water and exchange of gases.
Stomata and guard cellsThe tiny pores or openings in plant tissue, which allow for the exchange of gases are known as stomata.
The unique cells, which surround stomata and work to close and open the stomatal pores are known as guard cells.
Both these helps a plant to take in carbon dioxide at the time of photosynthesis and also assist in reducing the loss of water by getting closed when conditions are dry and hot.
Thus, stomata and guard cells work together to regulate the loss of water and gas exchange.

However, he cannot do this because __________. A chemist has discovered a drug that blocks an enzyme that catalyzes some of the reactions of glycolysis. He wants to use the drug to kill bacteria in people with infections. However, he cannot do this because __________. bacteria are facultative anaerobes; they usually don't need to perform glycolysis human cells also perform glycolysis; the drug might also poison them glycolysis can occur without the action of enzymes bacteria do not perform glycolysis glycolysis produces so little ATP that the drug will have little effect
Answer:
human cells also perform glycolysis; the drug might also poison them
Explanation:
Glycolysis is the first stage of cellular respiration, which is performed by every living thing to release energy for their cell's use. Glycolysis occurs in the cytosol, hence, it is undergone by every living organism whether prokaryotic or eukaryotic.
According to this question, a chemist is said to have discovered a drug that blocks an enzyme that catalyzes some of the reactions of glycolysis. His main aim is to use the drug to kill bacteria in people with infections. No matter his good intentions, he cannot use the drug on people because of its inhibitory effect on glycolytic reactions, which is also performed by human cells.
Therefore, the chemist cannot use the drug because human cells also perform glycolysis and the drug might also poison them.

Dendritic cells process antigens by
detection.
engulfment.
immunity.
inflammation.
Answer:
Dendritic cells are the most efficient antigen-presenting cells. They take up antigens and pathogens, generate MHC-peptide complexes, migrate from the sites of antigen acquisition to secondary lymphoid organs and, finally, they physically interact with and stimulate T lymphocytes. So it would most likely be inflammation.
Explanation:
Answer: Engulfment.

The first and third answers describe this form of induction. The second and third answers describe this form of induction.
Answer:
can be caused by interaction with MHC/peptide in the absence of costimulation
Explanation:
T cells represent a class of white blood cells (lymphocytes) that have a major role in the adaptive immunity of the organism against specific pathogens. Peripheral tolerance is a type of immunological tolerance aimed at ensuring B and T cells that escaped from the central tolerance mechanism do not produce autoimmune diseases. Some populations of lymph node cells can induce peripheral tolerance in T helper cells (Th cells, CD4+ cells) by the presentation of peptide-MHCII (major histocompatibility complex type II) complexes acquired from dendritic cells. These dendritic cells are antigen-presenting cells that play a key role in adaptive immunity, which are well-known to induce CD4 and CD8 T cell tolerance in response to antigens (peptides/proteins).
Define the meaning of the phrase entry requirements to higher education institutions and state four reasons why knowing the entry requirements is important
Answer:
Requirements needed by the students for the admission.
Explanation:
Entry requirements refers to the requirement needed by the students for the admission in the college or university. Knowing entry requirements is important because the university allows only those students who are eligible for the course. It provides information about the criteria on which students are selected for the admission. Due to these requirements, the students work harder and do more study to achieve the requirements that is necessary for the admission. Knowing the entry requirements will help students to collect or achieve the necessary things.

What force or forces constitute the fundamental source of energy that generates wind movement and circulation?
Answer:
The movement of wind is the result of the action of one or more forces on a particle of air, fundamentally the forces of the solar radiation, pressure gradient, coriolis, friction and centrifugal are recognized.
Explanation:
Air movement is caused by differential heating of the earth's surface and the atmosphere, which presents significant variations in time and space. Wind specifically refers to the horizontal movement of air parcels (which reach great distances and can persist on different time scales)Solar radiation is absorbed by the Earth, and this process is uneven. This irregular heating is what generates the wind. Pressure Gradient Force is determined by the pressure differences between two points in the atmosphere and tends to move the parcels of air from high to low pressure centers, in order to achieve barometric equilibrium. This force is responsible for causing the initial movement of the air. The Coriolis Force is an apparent force that occurs perpendicular to the direction of movement, generating a deviation in the wind path due to the rotation of the Earth (around its axis with an angular velocity). Centrifugal Force manifests itself as a radial pushing action from the center of a circle. In the atmosphere, it occurs in high- and low-pressure systems, leading outward from high- or low-pressure centers. The Friction Force is caused by the friction of the air with the earth's surface, causing a delay in the flow of air masses and changes in the direction of movement.

How do the organs of the excretory system work together to eliminate potentially harmful wastes from the body?
Answer:
This is the job of the excretory system. You remove waste as a gas (carbon dioxide), as a liquid (urine and sweat), and as a solid. Excretion is the process of removing wastes and excess water from the body. Recall that carbon dioxide travels through the blood and is transferred to the lungs where it is exhaled.

A private reptile breeding facility near the Everglades was destroyed by Hurricane Andrew in 1992. This event contributed to the original influx quantities of pythons in the wild. Pet owners also contributed to the introduction of these reptiles to the Everglades by releasing pets that had grown too large to care for. These reptiles are considered species to this ecosystem.
can someone please write an explanation that describes the impact of the Burmese python on the Everglades?
Claim:
Evidence:
Reasoning:
Answer:
Claim:
The increase in the population of the Burmese python in Everglades is affecting the ecosystem of said area. They are an invasive species.
Evidence:
From 1994 to 2007, the Burmese python population increased from a small number below 50 species to more than 250 by 2007. As the Burmese population increased, the mammals' population in Everglades decreased significantly and even had extincted some species. For example, from 1993 to 1999, there were 64 white-tailed deer and five red foxes, and grey foxes. Between 2003 and 2011, there were 24 white-tailed deers and 0 foxes. Overall, there is a decrease in all mammals.
Reasoning:
The increasing number of Burmese Pythons due to the release of them by pet owners and due to the destructions of a private reptile breeding facility left a high number of pythons in the wild. As a consequence, these pythons ate other animals producing an imbalance in the Everglades ecosystem. Owing to its large number and how they are harming the ecosystem, they are considered an invasive species.
Explanation:
After analyzing the information, the claim is that the increasing population of pythons harms the Everglades' ecosystem.
The evidence that supports the claim is present in the graphics, where we can see how the population of this reptile grew over the years, and the mammals' population decreased. There is specific information about the reduction in the number of mammals in the area, such as the raccoon, foxes, rabbits, etc.
After presenting the evidence, the reasoning that we can make is that the pythons are killing the other animals in Everglades. Also, we can see that they are not a native species from the area since they were released by pet owners and by a breeding facility by accident. The fact that they are harming the Everglades' ecosystem and that they are not native species makes them an invasive species.
