(06.02 MC) Which of the following correctly explains the role of antibiotics in the human body? (2 points) a They break down damaging toxins created by bacteria. b They increase the number of white blood cells in the blood. c They rupture the cell wall or prevent protein synthesis in bacteria. d They reduce the effects of fever, swelling, and inflammation in the body.
Answer:
The beneficial role of antibiotics in the human body is given because they produce rupture the cell wall or prevent protein synthesis in bacteria.
Explanation:
Antibiotics are a group of drugs that fight bacteria, eliminating them, to cure infectious diseases.
The mechanisms of action of antibiotics aim to break the bacterial protection or interfere with their vital functions to make them unviable:
Destruction of the bacterial wall or membrane. Interference with protein synthesis. Inhibition of the synthesis of nucleic acids.In general, the effects of antibiotics on bacteria are to rupture the cell wall or prevent protein synthesis. Through these mechanisms, antibiotics eliminate and prevent the reproduction of pathogenic bacteria, thus eliminating the infections they produce.
The other options are not correct because:
a. Breaking down damaging toxins created by bacteria is an anti-toxin function.
b. Antibiotics do not increase the number of white blood cells in the blood.
d. Reduction of the effects of fever, swelling, and inflammation in the body is a function of antipyretics and anti-inflammatories.
Answer:
They rupture the cell wall or prevent protein synthesis in bacteria.

Explanation:
Fungi, many birds, and a wide variety of insects all share the habitat of a tree in the forest. Part of the Choose... of the fungi is to obtain energy from dead organic matter, such as dead wood. Temperatures above 0°C and sufficient water in the environment help define the range of tolerance for fungi.
Answer:
1. Habitat, 2. Niche, and 3. Tolerance
Explanation:
The tree is a habitat for many organisms such as birds, fungi, and insects in the forest ecosystem as it provides shelter and food. Habitat can be understood as the address of an organism,
Fungi are saprophytic energy that obtains energy from the dead organic matter that presents on the tree, which is the niche of the fungi. Niche is like the job or work of an individual organism.
Fungi can grow in extreme temperature and waterlogging conditions which shows the tolerance of the fungi.

Describe the alternation of generations in plants. (2 points)
Answer:
Alternation of generations (also known as metagenesis) is the type of life cycle that occurs in those plants and algae in the Archaeplastida and the Heterokontophyta that have distinct haploid sexual and diploid asexual stages. ... The haploid spores germinate and grow into a haploid gametophyte.
Explanation:
yw
Answer:
Alternation of generations describes a plant's life cycle as it alternates between a sexual phase, or generation and an asexual phase. The sexual generation in plants produces gametes, or sex cells and is called the gametophyte generation. The asexual phase produces spores and is called the sporophyte generation.
Explanation:
What would happen to an animal cell with an internal salt concentration of 10% if it were placed in a salt solution with a concentration of 30%?
O The water would move out of the cell and the cell would decrease in size.
O The water would move into the cell and the cell would increase in size.
O The salt would move into the cell and the cell would increase in size.
O The salt would move out of the cell and the cell would decrease in size..
Answer:
The water would move out of the cell and the cell would decrease in size.
Explanation:
This question is depicting OSMOSIS, which is the movement of water from a region of high concentration (low solute concentration) to a region of low concentration (high solute concentration) across a semi-permeable membrane. This movement is caused when a concentration gradient forms between the two sides of the membrane.
In this case, an animal cell contains an internal salt concentration of 10% while the salt solution has a concentration of 30%. This means that the animal cell is hypotonic (contains high water concentration) to the salt solution, hence, water would move out of the cell and the cell would decrease in size

Some students were discussing running the mile in PE. The students all agreed that the cardiovascular system was very important but they could not agree on what other system was important.
Which of the following claims and reasoning would be MOST beneficial in their argument? (AKS 2b)
A.
Student 2 said the digestive system was also important because it breaks down waste produced by running, which the cardiovascular system transports to all the cells.
B.
Student 3 said the immune system was also important because it releases sweat from the body while running, which the cardiovascular system will transport away from all the cells.
C.
Student 1 said the respiratory system was also important because it brings oxygen into the body while running, which the cardiovascular system transports to all the cells.
D.
Student 4 said the muscular system was also important because it produces nutrients in the body while running, which the cardiovascular system will transport away from all the cells.

What do dermal tissues in plants do
Answer:
The dermal tissue system protects the soft tissues of plants and controls interactions with the plants' surroundings. The epidermis is a dermal tissue that is usually a single layer of cells covering the younger parts of a plant. It secretes a waxy layer called the cuticle that inhibits water loss.
Primary dermal tissues, called epidermis, make up the outer layer of all plant organs (e.g., stems, roots, leaves, flowers). They help deter excess water loss and invasion by insects and microorganisms.

A geologist is studying a mountain. It is made up of many relatively even
layers of igneous rock. What can the geologist conclude about how the
mountain formed?
A. It formed when an earthquake caused faults to form in a body of
rock.
B. It formed when a glacier melted and deposited rock and sediment.
C. It was formed by many layers of sediment piling up.
D. It was formed by a series of volcanic eruptions.
The mountain was formed by a series of volcanic eruptions. Option D
What can be concluded?The geologist can infer from the data that the mountain was created by a sequence of volcanic explosions. It is stated that the mountain is composed of numerous, generally uniform strata of igneous rock.
In most cases, molten material such as lava or magma that is ejected during volcanic eruptions solidifies to produce igneous rock.
Multiple igneous rock strata may accumulate over time while the volcanic activity persists, eventually producing a mountain.

which statement best explains what happens when a cell is placed in a sugar solution with a sugar concentration that is lower than that of the cytoplasm of the cell?
Answer:
B.
Explanation:
I'm not COMPLETELY sure, but usually water wants to always make everything equal, so in order to make the sugar levels in both even, it will leave the cell to increase sugar levels inside and decrease levels outside.
