Answer:
The mitochondria are defective and do not produce sufficient protein to synthesize microtubules in the cilia and flagella. The plasma membrane of the alveoli is not permeable to carbon dioxide during respiration because it is too hydrophobic. The cells do not produce functional motor proteins in flagella and cilia.
How does a bacteriophage work.
Answer:
A bacteriophage attaches itself to a susceptible bacterium and infects the host cell. Following infection, the bacteriophage hijacks the bacterium's cellular machinery to prevent it from producing bacterial components and instead forces the cell to produce viral components.

Why are common cold viruses difficult to cure?(1 point)
A copy of the DNA is made from the viral RNA.
The virus leads to other viral infections such as the flu and HIV.
The viral genome mutates very quickly.
Vaccines prevent the development of a cure.
Answer:
You are very correct the answer is c
Correct option is ''The viral genome mutates very quickly.''
Viruses can't reproduce on their own as bacteria do, instead, they attach themselves to healthy cells and reprogram those cells to make new viruses. It is because of all of these differences that antibiotics don't work on viruses. Antibiotics and medications treat bacterial infections. These antibiotics cannot treat or cure a common cold as colds aren't caused by bacteria.
Common cold viruses are difficult to cure as the viral genome mutates very quickly.

Mr. Carter draws a box with a particle diagram of a liquid on the whiteboard. Next, he draws another box with a particle diagram of a solid, but he leaves this box blank for one of his students to fill in.
What should Mr. Carter's student draw in the blank box?
Mr. Carter's student must draw particles very close together.
We can arrive at this answer as follows:
Mr. Carter is showing how the particles fit into a solid substance and a liquid substance.In a liquid substance, the particles are separated from each other, which allows the characteristic fluidity of liquids.In a solid substance, the particles are very close to each other, not allowing space between them.In this case, we can say that Mr. Carter's student, when drawing the particles of solid substance, must draw them very close to each other, not allowing any space between them, preventing them from moving.

Explanation:
A cell uses active transport to move sodium ions out of the cell. Why does the cell use active transport instead of diffusion to move sodium ions out of the cell?.
Answer:
A cell uses active transport because active transport uses energy going from high to low (against the concentraion gradient) while diffusion (passive transport which doesn't use energy) goes from low to high.
Explanation:
The cell uses active transport to move sodium ions out of the cell instead of diffusion because they are moved against a concentration gradient.
WHAT IS ACTIVE TRANSPORT?Active transport is the type of transport in which substances are moved from a region of higher concentration to a region of lower concentration.
This means that substances are moved against a concentration gradient, hence, requires energy in form of ATP to take place.

What should be done with the contents of
a composter? Explain your reasoning.
Answer:
Finally, the number of times the pile is turned influences composting speed. By turning more frequently (about every 2-4 weeks), you will produce compost more quickly. Waiting at least two weeks allows the center of the pile to heat up and promotes maximum bacterial activity. The average composter turns the pile every 4-5 weeks.
When turning the compost pile, make sure that materials in the center are brought to the outsides, and that materials from the outside edges are brought to the center.
With frequent turning, compost can be ready in about 3 months, depending on the time of year. In winter, the activity of the bacteria slows, and it is recommended that you stop turning the pile after November to keep heat from escaping the pile's center. In summer, warm temperatures encourage bacterial activity and the composting process is quicker
Using compost in the yard
Incorporate compost into your garden as you prepare the soil in the spring. Cover the area with 3-4 inches of soil and till it in to at least the upper 6 inches of soil. Add compost to soil in vegetable gardens, annual flower beds, and around new perennials as they are planted.
You may also use compost as mulch around flower beds, vegetable gardens, or around trees or shrubs in landscape beds. Apply a 3 inch layer. Be careful not to apply mulch close to the main stem or trunk of the plant.

Hypothalamic releasing and inhibiting hormones are carried directly to the anterior pituitary gland via hypothalamic-hypophyseal portal veins. Specific hypothalamic hormones bind to receptors on specific anterior pituitary cells, modulating the release of the hormone they produce.
Which part of a fish detects vibrations
and temperature changes?
Answer:
For each fish's skin surface, a row of unique cells is contained inside a particular canal that runs the length of its body. This is referred to as the "lateral line," because it enables them to sense vibrations in the water. Fish are able to notice activity around them as well as changes in the flow of water thanks to their sixth sense.

A type of biome that is very dry, with soil made mostly of sand and rock found in California is known as the desert.
What are biomes?Biomes has been considered as the higher level of organization than ecosystems. Biomes are land areas formed by the influence of climate, rainfall, and latitude. There are various kinds of biomes namely desert biome, prairie biome, savanna biome, tropical forest biome, deciduous forest biome, tundra biome, and mangrove forest biome.
The Mojave Desert is a desert that comprises parts of southern California and small parts of Northern California, southwestern Utah, southern Nevada, and northwestern Arizona, in the United States.
A desert is a biome which receives very little annual precipitation. As a result of this it exhibit very hot and dry climatic conditions. The soil generally losses it's fertility which may either become compact or remain in loose form due to erosion like sand. The plants exhibit fleshy leaves so as to prevent the loss of water through transpiration.

how can one eukaryotic gene lead to one transcript, but multiple different proteins?
Answer:
source- The ability of certain genes to form multiple proteins by joining different exon segments in the primary trans-cript is called alternate splicing and has caused a reexamination of the concept of “one gene, one protein.
Scientists have long known that it's possible for one gene to produce slightly different forms of the same protein by skipping or including certain sequences from the messenger RNA. ... Human genes typically contain several "exons," or DNA sequences that code for amino acids, the building blocks of proteins.
in your own words-
the flexibility of bound factors to make multiple proteins by connection totally different DNA segments within the primary trans-cript is termed alternate junction and has caused a reexamination of the thought of “one gene, one macromolecule.
Scientists have long noted that it's attainable for one factor to provide slightly totally different styles of a similar macromolecule by skipping or together with bound sequences from the informational RNA. ... Human genes usually contain many "exons," or desoxyribonucleic acid sequences that code for amino acids, the building blocks of proteins.
