In what cell phase(s) does chromosome production (replication) and formation (condensing) occur?
What are two different ways cells communicate and explain how this form of communication is effective?
Answer:
There are many different ways that cells can connect to each other. The three main ways for cells to connect with each other are: gap junctions, tight junctions, and desmosomes.
Explanation:
Cell Signaling is an important facet of biological life. It allows cells to perceive and respond to the extracellular environment allowing development, growth, immunity, etc. Additionally, errors in cell signaling may result in cancer growth, diabetes.

what are 5 functions of carbohydrates
☁️ Answer ☁️
PROVIDES INSTANT ENERGY TO THE BODY:
This appears to be the primary function of carbohydrates in the body.
Carbohydrates which we consume as food in the form of starch (ex: potato, bread), sucrose (ex: sugar, fruits), etc. get digested in the body to release glucose.
RESERVE FOOD:
Carbohydrate is also stored as the reserve food in the body. This is a precautionary measure for the body to cope up in times of hunger.
CARBOHYDRATES FORM OTHER BIOMOLECULES:
Carbohydrates in excess are converted into other bio-molecules of physiological importance. They mostly get stored in the form of fats.
DETOXIFICATION OF THE BODY BY METABOLISM:
Many drugs and toxic wastes in the body are metabolized for easy excretion in the body.
SPARING PROTEIN
In a situation where there is not enough glucose to meet the body’s needs, glucose is made from amino acids. Because there is no storage molecule of amino acids, this process requires the destruction of proteins, primarily from muscle tissue. The presence of adequate glucose basically spares the breakdown of proteins from being used to make glucose needed by the body.

Suppose you have the same mass of water and air. If you want to raise the temperature of water and air from 20°C to 30°C, which substance will require more energy, Q, to do so?
Answer:
Water has a higher specific heat than air. So, it will require more energy to raise the temperature of water from 20°C to 30°C compared to what is needed to raise the temperature of the same mass of air.

Define evolution in genetic terms.
Answer: The process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth.
Explanation:
Answer:
Evolution is defined as the process of growth and development or the theory that organisms have grown and developed from past organisms. ... An example of evolution is the theory started by Charles Darwin that theorizes about how humans came to be in their present form.

Why is it difficult to fossilize large animals?
Answer:
The onerous elements of organisms, like bones, shells, and teeth have a far better likelihood of changing into fossils than do softer elements. One reason for this can be that scavengers typically don't eat these elements. onerous elements conjointly decay additional slowly than soft elements, giving longer for them to be buried.

What would happen if the rate of evaporation reduces
Answer:
When temperature and wind speed are constant, but humidity increases, the rate of evaporation will decrease. When wind speed and humidity stay constant, and temperature increases, then the rate of evaporation will increase because warmer air can hold more water vapor than colder air.
Answer:
if the rate of evaporation reduces water cylcle will stops and amount of water present in the world will be increase.humifity will be more.
Meiosis is necessary for sexual reproduction in eukaryotic organisms. Which of the following statements below regarding meiosis is TRUE? *
A. Meiosis forms two cells all with the same genetic material
B. Meiosis forms two cells all with different genetic material
C. Meiosis forms four cells all with the same genetic material
D. Meiosis forms four cells all with different genetic material
Answer:
D. Meiosis forms four cells all with different genetic material
Explanation:
They are haploid cells and each cell only had one set of chromosomes. Meiosis results in variation.
DNA and RNA are made of what monomers? ___________________________
42. What are the 3 components of a nucleotide? ________________________________________
43. What are the elements found in nucleic acids?___________________________________
44. What are the 3 polymers for nucleic acids.________________________________________
45. What are the 2 main functions for nucleic acids.________________________________________________________________________
Answer:
42. Nucleotides are composed of three subunit molecules: a nucleobase, a five-carbon sugar (ribose or deoxyribose), and a phosphate group consisting of one to three phosphates. The four nucleobases in DNA are guanine, adenine, cytosine and thymine; in RNA, uracil is used in place of thymine
Explanation:
43.Nucleic acids contain the same elements as proteins: carbon, hydrogen, oxygen, nitrogen; plus phosphorous (C, H, O, N, and P). Nucleic acids are very large macromolecules composed of repetitive units of the same building blocks, nucleotides, similar to a pearl necklace made of many pearls.
44.polymer of nucleic acid
33 terms. The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). Threose nucleic acid (TNA) is an artificial genetic polymer in which the natural five-carbon ribose sugar found in RNA has been replaced by an unnatural four-carbon threose sugar.
