A form of a gene that has a slightly different sequence than other forms of the same gene but encodes the same type of an RNA or protein, is called a allele.
Allele- One of two or more variations of the DNA sequence (a single base or a segment of bases) at a certain genomic region is referred to as an allele. For each given genomic site where such variation exists, an individual receives two alleles, one from every parent. An person is homozygous for an allele if the two copies are identical.
Gene- The fundamental genetic component transferred from parent to child. Genes are composed of DNA sequences and are organized sequentially at specified sites on chromosomes.

The large differences observed in genomic size among eukaryotes correspond primarily to differences in?
Answer:
The large differences observed in genomic size among eukaryotes correspond primarily to differences in the amount of noncoding DNA
Explanation:
The whole collection of DNA and genetic information found in a given organism or cell makes up that organism's genome. For the majority of the time, when we think of genes, we consider those that produce proteins or those that are translated to mRNAs and then converted into proteins. But, genomes include much more than simply those that produce proteins. There is big difference in size and content of prokaryotic and eukaryotes. One mRNA generates one protein inside a eukaryotic gene in some kind of a biochemical or signaling pathway; operon organization is not present. A eukaryotic gene's numerous exons can really be cleaved in various ways to produce several mRNAs & proteins from just a single gene.

Can the nucleus be seen in the whole mount of the fern cells in the microscope slide?
No, the nucleus cannot be seen in the whole mount of the fern cells in the microscope slide.
What is nucleus?The nucleus is an organelle in cell biology that is membrane-bound and is present in eukaryotic cells. Eukaryotes typically have a single nucleus, but some cell types, like mammalian red blood cells, don't have any, and some others, like osteoclasts, have numerous nuclei. The nuclear envelope, a double membrane enclosing the entire organelle and separating its contents from the cellular cytoplasm, and the nuclear matrix, a network within the nucleus that adds mechanical support, much like the cytoskeleton supports the cell as a whole, are the two main components of the nucleus.

Muscle cells generate atp by burning fuel (glucose) and oxygen in a process called _____ respiration.
a. isometric
b. isotonic
c. anaerobic
d. aerobic
Muscle cells generate atp by burning fuel (glucose) and oxygen in a process called aerobic respiration.
Aerobic respiration is the process by which organisms convert fuel, such as fats and sugars, into chemical energy by using oxygen.
During aerobic cellular respiration, glucose reacts with oxygen to form ATP, which the cell can use. As a byproduct, carbon dioxide and water are produced.
The overall equation for aerobic cellular respiration is:
C₆H₁₂O₆ + 6O₂ --------------------> 6CO₂ + 6H₂O + ATP
Cellular respiration
All cells use respiration to convert fuel into energy that can be used to power cellular processes. Adenosine triphosphate (ATP) is the end product of respiration, and it uses the energy stored in its phosphate bonds to power chemical reactions. It is frequently referred to as the cell's "currency."

How does the bottleneck effect undermine the effort of conservation biologists who are trying to save species nearing extinction?.
Bottleneck effect helps the biologists to save species nearing extinction because it helps in reestablishment of the species.
Specified, widespread violence or purposeful culling, human population planning, and other human actions such as famine, earthquakes, floods, fires, disease, and droughts can all cause population bottlenecks. Population bottlenecks can also occur owing to genetic bottlenecks. Such occurrences can lessen the genetic variety of a community, leaving just a smaller population to transmit genes to future generations of offspring through sexual reproduction.
from such a small population by continuously breeding and providing good environment the again flourishment of the species can take place.
Thus, this small population is now taken care of by biologist so that the proper sexual reproduction can take place and thus the population is maintained and thus conservation takes place.

If a bacterial isolate shows intermediate to moderate resistance to an antibiotic, how might this drug still be successfully used in the treatment of this microbe?
Answer:
Bacteria have become resistant to several antibiotics due to the extended usage of antibiotics. It could show moderate, severe, or intermediate tolerance. This resistance gives microorganisms a way to defend themselves from the antibiotic. Such antibiotics operate as stresses rather than being able to stop bacterial development or destroy it. The use of such antibiotic medications is changed in quantity or changed according to intensity to provide beneficial outcomes. The use of antibiotics for bacteria may be raised in dose in cases of medium to severe resistance manifestation to suppress bacterial activity and battle bacterial resistance. Additionally, for optimal outcomes, the antibiotic might be used with other medications.

Muscle Hypertrophy is what causes the muscle to grow.
To follow Hypertrophy 'Muscle under Stress' is an important component while working out. It is directly proportional to the growth of muscles. These are three mechanisms for muscle growth.
Muscle Stress: In order to grow muscle, it should be kept under a lot of tension using weights and the tension should be more than the body is adapted to. This is a concept of Progressive Overloading your muscle.Muscle Damage: After working out, Muscle Fibres get torn up. This local muscle damage causes a release of inflammatory molecules and immune system cells that activate satellite cells to jump into action.Metabolic Stress: It causes the cells around the muscle to swell. This is from the addition of muscle glycogen which helps muscle and the connective tissue to get swollen up. It is often referred to as 'PUMP'.After Working out, due to tears in muscle fibers, the protein-synthesizing rate should be high which is absorbed by the muscle and causes to muscle fiber repair and grow.
