Answer:
They fit the proteins on the surface of the host cell.
Explanation:
The proteins in a virus's outer coat play a significant role in the attachment with the host cells and invade the host body.
What do you mean by Virus?A Virus may be defined as a microorganism that infects cells and may cause diseases.
The outer coat of the virus consists majorly of spike proteins that attach to the host cells and enter the body through the process of endocytosis.
Therefore, the proteins in a virus's outer coat play a significant role in the attachment with the host cells and invade the host body.

explain how the scientific theory of evolution is supported by molecular biology
The theory of evolution is supported by molecular biology because the linear order of nucleotides and sequence homo-logy may be useful to show a common origin.
What is sequence homo-logy?The expression sequence homo-logy makes reference to the similarity level between two or more sequences (e.g., DNA sequences) in organisms.
The sequence homo-logy can be very useful to show a common evolutionary origin in a group of organisms.
The sequence homo-logy refers to the linear sequence of nucleotide bases in the DNA molecule.

Define Photosynthesis.
Answer:
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.
The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.

based on the text how would you define a dominant gene what about a recessive gene
Dominant refers to the relationship between two versions of a gene. Individuals receive two versions of each gene, known as alleles, from each parent. If the alleles of a gene are different, one allele will be expressed; it is the dominant gene. The effect of the other allele, called recessive, is masked.

If your heart beats 70 times per minute, everyday of the year, how many times does it beat in a year?
Answer:
36,792,000
Explanation:
Using some math, if you say that it beats at 70 pm, then you should look for how much it beats in an hour, which is 4200 (60x70). Then you have to take that number and multiply by 24, which is 100,800. In a day it beats about that amount. Then you take that number and multiply by 365, which is 36,792,000.

We have to finish dividing the cytoplasm and then back to work. Can’t wait to get back to normal
The cell cycle is a process characterized by finishing when dividing the cytoplasm and then the daughter cells back to work.
What is the cell cycle?The cell cycle is a series of cellular events that undergo a cell from its formation to its division.
The cell cycle can be divided into an interphase and a mitotic (M) phase, which ends with a process called cytokinesis.
The cytokinesis refers to the division of the cytoplasm, which is required to form two daughter cells.

A type of ribonucleic acid that Incodes genetic information
Answer:
Explanation:
Cellular organisms use messenger RNA (mRNA) to convey genetic information (using the nitrogenous bases of guanine, uracil, adenine, and cytosine, denoted by the letters G, U, A, and C) that directs synthesis of specific proteins. Many viruses encode their genetic information using an RNA genome.
Inadequate blood flow to the heart muscle can cause an area of damaged cardiac tissue known as a(n) .
A myocardial infarction comprises a series of changes in the cardiac tissue that originate when there is an inadequate blood flow to the heart muscle or a coronary artery becomes blocked.
What is a myocardial infarction?It is characterized by the sudden appearance of a picture of ischemic suffering (lack of irrigation) to a part of the heart muscle produced by the acute and total obstruction of one of the coronary arteries.
It is recognized by the sudden appearance of the characteristic symptoms of intense pain in the chest, in the precordial area and a feeling of general malaise.
Therefore, we can conclude that a myocardial infarction comprises a series of changes in the cardiac tissue that originate when there is an inadequate blood flow to the heart muscle.

The processes of transcription and translation are critical pieces of gene expression to produce proteins in all living cells on earth.
Which statements correctly differentiate transcription and translation? More than one statement may apply.
Transcription is the process of synthesizing RNA from DNA, while translation is the process of synthesizing proteins from RNA.
Transcription involves the production of a complementary RNA copy of a DNA sequence, using RNA polymerase and nucleotides. The resulting RNA molecule, called messenger RNA (mRNA), carries genetic information from the DNA in the nucleus to the ribosomes in the cytoplasm.
Translation, on the other hand, involves the reading of the mRNA sequence by ribosomes, which assemble amino acids into a polypeptide chain according to the genetic code. This process involves transfer RNAs (tRNAs) that carry specific amino acids and match them to the codons on the mRNA. Together, transcription and translation enable the transfer of genetic information from DNA to proteins, which perform vital functions in cells.

how does the changing nature of water rights relate to the investigation phenomenon
Answer:
Natural disasters are caused due to different reasons like soil erosion, seismic activity, tectonic movements, air pressure, and ocean currents etc. Natural activities taking place in the earth's crust, as well as surface, are the main reasons for these disasters.
We are running out of water due to change in climate conditions like floods, droughts, sea level rising.
Reasons of water running out:Drought- The world’s changing climate has been linked to an increased incidence of droughts that results in increase demand of water supply.Sea level rising- Rising sea level increases the salinity of both surface water and ground water through salt water intrusion.Increasing population-About 70% of the world’s freshwater consumption is for agriculture and food demand is rising. The global population is increasing, which will increase global food demand and this will increase the water required for food production.you can learn more about this water changes here:

What are Heterotrophs known as ?
Answer:
An organism that doesnt not produce its own food
Explanation:
Heterotrophs are consumers who eat other organisms for food, while autotrophs or producers make food by process of photosynthesis.
Answer:
A heterotroph is an organism that eats other plants or animals for energy and nutrients. The term stems from the Greek words hetero for “other” and trophe for “nourishment.”
Organisms are characterized into two broad categories based upon how they obtain their energy and nutrients: autotrophs and heterotrophs.
Heterotrophs are known as consumers because they consume producers or other consumers. Dogs, birds, fish, and humans are all examples of heterotrophs.
Heterotrophs occupy the second and third levels in a food chain, a sequence of organisms that provide energy and nutrients for other organisms. Each food chain consists of three trophic levels, which describe an organism’s role in an ecosystem. Occupying the first trophic level are autotrophs, such as plants and algae. Herbivores—organisms that eat plants—occupy the second level. Carnivores (organisms that eat meat) and omnivores (organisms that eat plants and meat) occupy the third level. Both primary (herbivores) and secondary (carnivores and omnivores) consumers are heterotrophs, while primary producers are autotrophs.
A third type of heterotrophic consumer is a detritivore. These organisms obtain food by feeding on the remains of plants and animals as well as fecal matter. Detritivores play an important role in maintaining a healthy ecosystem by recycling waste. Examples of detritivores include fungi, worms, and insects.
