Answer:
b. The genes for antibiotic resistance are located on a plasmid that can be passed to neighboring bacteria.
Explanation:
Conjugation refers to the process where one bacterium known as 'donor' transfers genetic material to another bacterium by direct contact. Conjugation enables bacteria to transfer genes that encode proteins conferring antibiotic resistance to another bacteria by transferring plasmids (i.e., small, extrachromosomal DNA molecules) containing these genes, which is known as horizontal transference. Plasmids that contain multiple antibiotic resistance genes confer Multidrug drug resistance (MDR) and they may severely limit the therapeutic efficacy of treatments against bacteria.
There are different kinds of antibiotics. The statement that best explains how the genes for antibiotic resistance can be transmitted between bacteria without the exchange of bacterial chromosomal DNA is that;
The genes for antibiotic resistance are located on a plasmid that can be passed to neighboring bacteria.Bacteria are known to be able to get antibiotic resistance genes from other bacteria in different ways. It can be gotten when they undergo a simple mating process referred to as "conjugation".
Bacteria are known to transport genetic material such as genes encoding resistance to antibiotics that are resident on plasmids and transposons. This can be transferred from one bacterium to another.

Proteoglycans are part of the extracellular matrix; they provide structure, viscosity and lubrication, and adhesiveness. They are composed of proteins conjugated to carbohydrate components called glycosaminoglycans. The glycosaminoglycan component makes up the majority of the mass of a proteoglycan. Which of these are possible components of glycosaminoglycans
Answer:
This question lacks options, options are: a. beta-D-fructofuranose b. amylose c. uronic acid d. N- acetylglucosamine. The correct answers are c and d.
Explanation:
Glycosaminoglycans are very long, unbranched polysaccharides, made up of repeating units of disaccharides. One of the disaccharides is always an amino sugar, which can be N- acetylglucosamine. The other is uronic acid (it can be iduronic acid or glucuronic acid and is often sulfated at position 2). The amino sugar is usually sulfated and the rest of the sugars have carboxyl groups, which give the structure a negative charge, which attracts a large amount of cations such as sodium. Glycosaminoglycans are often covalently bound to proteins to form proteoglycans. Hyaluronic acid is the only glycosaminoglycan that does not form protein bonds and does not have sulfate groups in its structure.

A liver cell has a volume of 5000 μm3. Its total membrane area, including the inner membranes lining organelles as well as the cell membrane, is 110,000 μm2. A cell in the pancreas that manufactures digestive enzymes has a volume of 1000 μm3 and a total membrane area of 13,000 μm2. Which cell is probably more efficient in carrying out activities that require extensive membrane surfaces? Why?
Answer:
The liver cell, since it has a higher surface to volume ratio will be more efficient in carrying out activities that require extensive membrane surfaces such as solute transport.
Explanation:
The cell surface area to volume ratio is important in order to determine the efficiency of the cell in carrying out its metabolic activities. The surface area of a cell is bounded by the cell membrane whose function in addition to many others is to let nutrients into the cell and let waste out of the cell. The rate of activity of a cell depends on its volume. The larger the volume the more the active the cell is. Since volume increases much more when compared to area, the ratio of the surface area of a cell to its volume becomes smaller with increase in volume of the cell.
Considering the liver cell and the pancreas cell in the question, the cell's surface area to volume ratio is given as follows:
Liver cell: volume = 5000 μm³; area = 110000 μm²
surface area to volume ratio = 110000 / 5000 = 22 : 1
Pancreas cell : volume = 1000 μm³ ; area = 13000 μm²
Surface area to volume ratio =13000 / 1000 = 13 : 1
The liver cell, since it has a higher surface to volume ratio will be more efficient in carrying out activities that require extensive membrane surfaces such as solute transport.

Which are characteristics of life?
Answer:
All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing. When viewed together, these characteristics serve to define life.
Explanation:
The level of glucose in the bloodstream drops. The person requires glucose in cells to meet the demand for ATP (glucose is broken down to create ATP). The body detects glucose levels with a particular receptor designed for this function. These receptors release hormones, chemical messages that initiate the start of the feedback mechanism. The hormones travel to their target tissue and initiate a corrective response. In this case, the corrective response is the secretion of more glucose into the bloodstream. Does this demonstrate POSITIVE or NEGATIVE FEEDBACK?
Answer:
Negative feedback.
Explanation:
It is negative feedback because the reactions triggered by low glucose levels are trying to rebalance the glucose concentrations in our body to make it work properly.
In positive feedback, a product will only stimulate more the components that lead to that product to produce more of it, increasing the product's effect and an imbalance.

define atomic number and mass number – describe how they differ
Answer:The major difference between atomic number and mass number is that the atomic number states the number of protons present in an atom whereas, the mass number indicates the total of the number of protons and the number neutrons present in an atom.i) Atomic number is the total number of protons present in the nucleus of an atom. It is also equal to the number of electrons for a neutral atom. Example, atomic number of sodium is 11. ii) Mass number is the number of protons and neutrons in the nucleus taken together. For example, mass number of sodium is 23 g/mol.

What do the arrows indicate?
Air moves in a direction that creates land breezes.
Air above land warms faster than air above water.
Air blows over long distances in a continual straight path.
Air pressure remains the same while cycling over land and water.
Answer: Air moves in a direction that creates land breezes.
Explanation:
The arrows indicate is air moves in a direction that creates land breezes. So, the correct option is A.
What are Land breezes?Due to the difference in temperature of land and sea, land breezes are those winds which blow from land to sea at night.
The Sun heats both land and sea during the day, but land heats up more quickly than water. As a result, an area of low pressure is generated as the air above the ground is heated and rises. As a result, cold sea air fills the space and creates a sea breeze that blows from sea to land.
The opposite happens at night. The air over the land becomes cooler and denser because the land cools faster than the sea. As a result, high pressure develops over the land. Then a land breeze is generated, which flows from land to sea by cold and dense air moving from land to sea.
So, the correct option is A.

Pls answer will mark brainliest to first person! I will report if it does not relate. Research an internal organism that has adapted over time to allow the species to perform specialized functions. Describe how the internal structure helps the organism survive in its ecosystem.
Answer:
An organism that was adapted over time to perform specialized functions is the saddleback tortoise which adapted slowly over time. Saddleback tortoise have shells that rise in front, like a saddle. This adaptation makes it easier for them to lift their heads high to eat tree cactus. This helps the tortoise survive by letting it reach a food source and not starve.
