Answers
Answer:
300 m³
Explanation:
Given that,
→ L = 12 m
→ W = 5 m
→ H = 5 m
The formula we use,
→ V = L × W × H
Now the volume of swimming pool is,
→ L × W × H
→ 12 × 5 × 5
→ 12 × 25
→ 300 m³
Hence, the volume is 300 m³.

The _____ is the bacterial structure that acts as a selective barrier, allowing nutrients to enter the cell and wastes to leave the cell.
Answers
The plasma membrane is the bacterial structure that acts as a selective barrier, allowing nutrients to enter the cell and wastes to leave the cell.
The cell membrane or plasma membrane can be described as a selectively permeable membrane that allows the selective entry of materials into and out of a cell. All the organelles of a cell are enclosed in the plasma membrane and hence it separates the interior of a cell from the exterior.
For single-celled organisms, such as bacteria, nutrients are received by the cell through the plasma membrane and excretion of waste also occurs through the plasma membrane. The bacterial cell membrane is made up of phospholipids and usually, it encloses a food particle in it for absorption of food.

If one or more nucleotide pairs are deleted from a dna strand, this is known as a :________
a. frameshift mutation
b. point mutation
c. missense mutation
d. silent mutation
Answers
Answer:
If one or more nucleotide pairs are deleted from a DNA strand, this is known as a :frameshift mutation
Explanation:
Due to deletion changes occur in the sequence of DNA when at least one nucleotide is removed in a gene.
The point mutation is just a type of genetic modification in which only one nucleotide base from either the DNA or RNA code of an organism is modified, added, or removed.
A missense is just a type of point mutation in biology that causes a codon to encode for a various amino acid as a consequence of a single nucleotide modification. Sickle cell disease or anaemia is an good example of this kind of mutation.
Silent mutations are the kind of mutations in which DNA can not affect the phenotype of an organism. They represent a particular kind of neutral mutation.
So, the correct option is frameshift mutation (A).

The __________ of the sperm contains enzymes involved in the penetration of the egg.
Answers
The acrosome of the sperm contains enzymes involved in the penetration of the egg.
By utilizing this maternal investment, the sperm is enhanced to spread the paternal genes; typically, it is extremely motile and streamlined for speed and efficiency during the task of fertilization. Only a small percentage of the billions of sperm generated during a human male's reproductive life actually succeed in fertilizing an egg due to intense competition amongst them. The tail, which directs the sperm to the egg and aids in its penetration of the egg coat, and the head, which houses a condensed haploid nucleus, are the two morphologically and functionally separate sections that typically makeup sperm. Because of the highly close packing of the DNA in the nucleus, transcription is stopped and its volume is reduced for transport.
Many sperm lack the somatic cell histones and instead have simple, extremely positively charged proteins called protamines packed within their chromosomes.

A community of plants, animals, and fungi that have attained steady state through the process of ecological succession in the growth of the vegetation in an area over time is referred to in scientific ecology as a climax community or climatic climax community.
Because the climax community is made up of species that are best adapted to the region's typical conditions, it was believed that this equilibrium would emerge.
The climax community's species composition doesn't change since all of the existing species are able to reproduce, whereas invasive species are unable to establish a presence.

During the citric acid cycle, an acetyl coa molecule produced in the intermediate stage combines with a molecule of:_______
Answers
During the citric acid cycle, an acetyl co A molecule produced in the intermediate stage combines with a molecule of oxaloacetic acid.
The primary energy source for cells and an important part of aerobic respiration is the tricarboxylic acid (TCA) cycle, sometimes called the Krebs or citric acid cycle. This cycle converts the chemical energy of acetyl-coenzyme A (acetyl-CoA) into the reducing power of nicotinamide adenine dinucleotide (NADH), which is further oxidized and enters the TCA cycle as acetyl-CoA. The intermediate half of the cycle also serves as the starting point for pathways leading to important molecules such as fatty acids, amino acids, and porphyrins. If any of these intermediates are diverted in this way, the integrity of the cycle is compromised and the cycle ceases to function. Only when the diverted intermediate, or the subsequent intermediate leading to oxaloacetate, is replaced by a replenishment (replenishment) process can significant energy production resume.The correct answer is oxaloacetic acid.
