Answer:
Leukocidins.
Explanation:
Intracellular pathogens sometimes produce leukocidins that can kill phagoctytes because leukocidins is a type of cytotoxin that is produced by pathogens which kill the phagocytes producing pathogens. The phagocytes destroy pathogens by engulfing the pathogens and destroying it by chemical toxins present inside the phagolysosome which is by a process called phagocytosis. The leukocidin kill phagocytes that engulf the pathogens making the pathogens to be able to affect the organism in which it invade.

Water vapor
could you help me i will give brainlyest
The substance that is a matter in its gas form is water vapor (option D).
What is gaseous state of matter?Matter refers to anything that has mass and occupies space. Matter is the basic structural component of the universe.
Matter is virtually everything around us and can exist in three states as follows:
SolidGaseous LiquidSolid is any substance that can be picked up or held, having a texture, and usually firm. Liquid is a substance that is flowing, and keeping no shape, such as water. It is a substance of which the molecules retain no definite shape, except that determined by the containing receptacle. Gases, on the other hand, is matter in an intermediate state between liquid and plasma that can be contained only if it is fully surrounded by a solid.Water vapor is an example of gaseous material, hence, can be said to be in gaseous form among the options.

In light of the above statements, how should developing countries deal with the problems associated
with a lack of clean, fresh water?
Consider the following food chain… Grass, beetles, raccoons, and coyotes live in a forest ecosystem. When a raccoon eats a beetle, the matter that made up the beetle’s body is transferred to the raccoon, and the total amount of matter in the ecosystem…
The total amount of matter in the ecosystem basically 'remains the same. The matter is recycled in the ecosystem, so its total amount is not changed'.
What do you mean by ecosystem?
An ecosystem is a community of living organisms (plants, animals, and microbes) and their physical environment interacting as a system. The complex network of interactions between the living organisms and their environment, including their interactions with one another, is known as an ecosystem.
Matter is a finite resource, meaning that it cannot be created or destroyed. When a raccoon eats a beetle, the matter that makes up the beetle's body is transferred to the raccoon, but it does not leave the ecosystem. The matter is simply being recycled and reused in the ecosystem. This means that the total amount of matter in the ecosystem remains the same, even though the material is being used by different organisms.

The diagram below represents a biological process. Which set of molecules is best represented by letters A and B?
Answer:
A: carbon dioxide and water
B: glucose
Explanation:
The diagram below represents a biological process. The molecules representing the letters A and B are:
A: carbon dioxide and water
B: glucose
What is a biological process?A biological process is an action that an organism does to accomplish a particular goal that is written into its genetic code. The outcome or final state of biological processes is frequently used to characterize them, for example, the biological process of cell division produces two daughter cells (a divided cell) from a single parent cell.
The primary form of sugar in the blood, glucose, serves as the body's cells' main source of energy. The body can produce glucose from other substances or from the foods we ingest.
Due to food digestion and oxygen inhalation, the organism's body exhales carbon dioxide back into the environment.
Therefore, the molecules representing the letters A and B are:
A: carbon dioxide and water
B: glucose

2. Tay-Sachs disease is a human genetic abnormality that results in cells accumulating and becoming clogged with very large, complex, undigested lipids. Which cellular organelle must be NONfunctioning in this condition?
a. the rough endoplasmic reticulum
b. the golgi apparatus
c. the lysosome
d. the mitochondrion
Answer:
The correct option for question 1 is
Option A.
permeability to glucose will increase
2. Correct option is C.
The lysosome.
Explanation:
1. increasing the proportion of saturated phospholipids in lipid bilayer will increase the permeability of glucose because normally the phospholipid bilayer is impermeable to most water insoluble substances like glucose, therefore to increase glucose permeability by the membrane saturated phospholipids need to be increase in the bilayer becayse saturated phospholipids tails have no double bonds and they are straight making it permeable to glucose.
2. The cellular organelles non functioning in Tay-Sachs disease is lysosome because lysosome is an organelles found in eukaryotic organisms that contain the digestive enzymes which help to digest food. In the case of Tay-Sachs, her lysosome is not functioning that is why there is accumulation of large complex undigested lipids because the lysosomes is malfunctioning and digestion cannot take place.
PLEASE HELP! Predict one potential explanation for why the number of H+ passing through ATP synthase decreases in this scenario.
In eukaryotes, aerobic respiration relies on a gradient where H+ are concentrated between the inner and outer mitochondrial membranes. This gradient is used as an energy source when H+ flow through the channel protein, ATP synthase. If the mitochondrial membrane is suddenly exposed to heat, the number of H+ flowing through ATP synthase decreases.
Answer:
In chemiosmosis, the energy stored in the gradient is used to make ATP. ... Electrons are passed from one member of the transport chain to another in a series of redox ... I to IV. In eukaryotes, many copies of these molecules are found in the inner ... The transport chain builds a proton gradient across the inner mitochondrial

The observation that a mammal and a fish can both have fins is an example of
A. analogy
B. parsimony
C. ancestry
D. homology
Answer:
D. homology
Explanation:
This observation is an example of the term known as homology. This is basically comparing how different species can have the same traits and physical design as each other even though they are completely different. This is due to the two species sharing a specific ancestor. That ancestor's trait is passed down throughout the generations even after the split and ends up in two different species.

For example, red flowers and white flowers would breed ____________ flowers unless ____________ in the genetic material existed.
Answer:
For example, red flowers and white flowers would breed pink flowers unless instability in the genetic material existed.
Note: The complete answers are provided in the explanation below
Explanation:
Prior to Mendel's work on genetics using pea plants hypotheses were proposed to explain heredity.
One of these hypotheses supported the blending concept of inheritance.
Most breeders acknowledged that both sexes contributed equally to offspring traits to create offspring with intermediate traits.
For example, red flowers and white flowers would breed pink flowers unless instability in the genetic material existed.
However, this model of inheritance didn't account for the presence of non-intermediate traits that exist in populations

The half-life of carbon-14 is about 7000 years. Assume that a tree died and became a fossil 14,000 years ago. How much of the original carbon-14 would you find in the wood today?
Answer:
One-fourth of the original carbon-14 isotope would be found in the wood today.
Explanation:
The half life of carbon-14 7000 years
Since the tree died and became a fossil 14000 years ago, number of times the tree has undergone decay in 14000 years = 14000/7000 = 2
Therefore, the carbon-14 would have undergone decay twice or passed through two half-lives
After one decay, 1/2 of the original sample remains
After another decay, 1/2 * 1/2 = 1/4 of the original sample remains.
Therefore, one-fourth of the original carbon-14 isotope would be found in the wood today.
