1. Why wouldn't bacteria be able to
survive on salted fish? Explain using the
concept of osmosis.
Answers
Salt kills some types of bacteria, mainly by sucking water out of them and this process called as osmosis. Osmosis is refer to as a water passes out of a bacterium so as to balance salt concentrations on each side of its cell membrane. At that time bacteria inside act as hypotonic medium.
What is hypotonic solution?A solution will be hypertonic to a cell if its solute concentration is higher than that inside the cell, and the solutes cannot cross the membrane.
Without water, bacterial also proteins such as enzymes cannot function and generally the cell collapses in on itself.

which of the following pairs of complementary nucleotides can be found in dna? select one: a. [a-c] b. [a-g] c. [a-t] d. [a-a]
Answers
The correct answer is option c. Complementary nucleotides are the base pairs that make up DNA strands. Adenine (A) always pairs with thymine (T) and cytosine (C) always pairs with guanine (G).
Therefore, the complementary nucleotides for A are T, for C are G, for G are C, and for T are A. Option a is incorrect because A and C are not complementary nucleotides.
Option b is incorrect because A and G are not complementary nucleotides. Option d is incorrect because A and A cannot form a base pair. In summary, the complementary nucleotide pair for A is T, and for T is A, which can be found in DNA.
In DNA, complementary nucleotides form base pairs according to specific rules. Among the given options, the correct pair of complementary nucleotides is [A-T], which stands for adenine (A) and thymine (T). Adenine always pairs with thymine, while cytosine (C) pairs with guanine (G). This base pairing ensures the stability and accurate replication of the DNA molecule during cell division.

which type of cell division takes place to heal the wound and why? a) Amitosis. b) Mitotic. c) Meiosis. d) Free Nuclear.
Answers
The type of cell division that takes place to heal a wound is mitotic cell division.
Mitotic cell division, also known as mitosis, is the process by which a single cell divides into two identical daughter cells. This type of cell division is responsible for growth, tissue repair, and wound healing in multicellular organisms.
When a wound occurs, the body initiates a series of events to repair the damaged tissue. One of these events involves cell division to replace the lost or damaged cells. Mitotic cell division allows for the replication of cells that are essential for tissue regeneration and healing.
During mitosis, the parent cell undergoes a series of phases, including prophase, metaphase, anaphase, and telophase, followed by cytokinesis. Each phase ensures the faithful replication and distribution of genetic material to the daughter cells, resulting in two identical cells with the same genetic information.
Mitotic cell division is vital for wound healing as it replenishes the damaged tissue by generating new cells to replace the injured or dead cells. This process promotes tissue regeneration and ultimately contributes to the healing of the wound.

e) The allele for small size is recessive, and the allele for normal size is dominant. The frequency for the normal-size allele is 0.72. What percentage of the rats are normal sized? (3 points)
Answers
Answer:
51.84%
Explanation:
p² + 2pq + q² = 1 and p + q = 1
p = frequency of the dominant allele in the population
q = frequency of the recessive allele in the population
p² = percentage of homozygous dominant individuals
q² = percentage of homozygous recessive individuals
2pq = percentage of heterozygous individuals
p = 0.72 => p² = 0.72² = 0.5184
=> Percentage of the rats are normal sized: 51.84%

Hi, you've asked an incomplete question. The full question reads;
1. Identify the:
Control GroupIndependent VariableDependent Variable2. Explain whether the data supports the advertisement's claims about its product.
Answer:
Subject AThe "certain itch powder"The time of itchinessExplanation:
1. Remember, the Control group in research often refers to the group in a research experiment that who are not subjected to any treatment, rather they are used as a comparison scale to see how other tested subjects perform.
We also need to note here that the independent variable here refers to a variable or factor that does not change (ie it is independent), but which results in changes in other variables. From the study, the "certain itch powder.""The time of itchiness" is a dependent variable because it does change, or can be affected by the independent variable.2. Remember, the advertisement of the "certain itching" "claims to cause 50% longer lasting itches". Hence, we can conclude that the data support the advertisement claims since subject B did itch over 50% longer than subject A. In fact, we are subject B itched for 10 hours, not the 30 minutes subjet A itched.
a mutagen has introduced a frame shift mutation by adding one nucleotide base. which of the following could be a reversion mutation for this particular mutant?
Answers
A possible reversion mutation for a frame shift caused by the addition of one nucleotide base would be the deletion of that added nucleotide base. This deletion would restore the reading frame and potentially revert the mutant phenotype to the wild-type phenotype.
What could reverse a frame shift?A frame shift mutation caused by the addition of a nucleotide base disrupts the reading frame of the gene, leading to a change in the amino acid sequence downstream of the mutation.
Reversion mutations occur when the effects of the original mutation are reversed, restoring the wild-type phenotype. In the case of a frame shift mutation, a reversion mutation could involve the deletion of a nucleotide base within the mutated region.
This deletion would effectively shift the reading frame back to its original state and potentially restore the correct amino acid sequence. However, it is important to note that the specific location and context of the mutation within the gene will determine the exact sequence changes required for reversion.

Compare the species richness, species diversity, and species evenness in the two areas. Describe two factors you think
could account for the differences in species richness/diversity/evenness in the two areas.
!!Please answer in 2 sentences!!
Answers
Species richness and species diversity are two crucial metrics ecologists employ to define the make-up of a community.
A community's species richness is determined by how many distinct species it contains. E.g., the second community would have a substantially higher species richness than the first if we identified 30 species in one community and 300 species in another.Near the equator, where there is a high concentration of solar energy, warm temperatures, abundant rainfall, and little seasonal variation, are typically where communities with the highest species richness can be found. Near the poles, which receive less solar energy and are colder, drier, and less conducive to life, are communities with the lowest species richness.The complexity of a community is gauged by its species diversity. It depends on both the community's species richness (the number of different species present) and species evenness (the relative abundances of those species).Greater species diversity would be seen in a forest community with 20 distinct tree species than one with only 5 distinct tree species .Numerous interrelated biotic (living things) and abiotic (non-living) factors contribute to the structure of a community (living organism-related): the climate of the communitythe location of the community geographicallyThe environment's heterogeneity (patchiness)how often disturbances or disruptive incidents occurinterspecies interactions.Learn more about species diversity here:

Explanation:
This is because in complete metamorphosis, frog develop from egg to adults. Metamorphosis refers to change of shape and growth in different stages of animals life cycle.
Frog mate in the rainy season.
There are four stages of frog metamorphosis and they are;
1 Egg : the female mate with the male and the male fertilizes the egg. The female releases the fertilized egg inside water , they egg are jelly like or cover with jelly covering.
2. Tadpole: the egg then hatched into tadpoles. The tadpoles live in water, it does not have lungs and limbs. It move like fish and uses gills to breathe. At this stage it starts developing hind limbs and later lungs. It has long tail
3. Froglet : At this stage, the lungs and the front legs develop. It floats above the water to breathe. The tail become shorter and it uses nutrients stored in the tail to feed or survive.
4. Adult : this is the final stage, the young frog leave water and start live on land, it's tail disappear completely and it's start feeding on insects.

at a given temperature and pressure, it takes 24 hours for a 1.5-l sample of he gas to effuse through a porous membrane. how long does it take for 1.5-l of o2 gas to effuse under the same conditions through the same membrane?
Answers
The time taken by the 1.5 L of O2 gas to effuse under the same conditions is also 24 hours.
Effusion of gas is the process of a gas passing through a porous wall or membrane, such as a filter, due to pressure differentials on either side of the wall or membrane. It is the opposite of diffusion, which is the process by which molecules move from an area of higher concentration to an area of lower concentration.
It takes 24 hours for a 1.5-l sample of the gas to effuse through a porous membrane. We need to calculate the time taken by 1.5 L of O2 gas to effuse under the same conditions.
This is because the rate of effusion of a gas is directly proportional to its molecular weight. Therefore, since both gases have the same molecular weight, they will take the same amount of time to effuse through the membrane.
