Answer:
The correct answer is - option C. A gene mutation interferes with cell cycle control mechanisms, resulting in uncontrolled cell proliferation.
Explanation:
Genetic mutations resulting in the change or absence of any regulatory proteins that used during checkpoints can result in the mechanism of turning on or turning off the cell cycle or allow a cell to move further for the division. Due to this change, the checkpoints are not able to prevent it from division.
Uncontrolled multiplication or proliferation of the cell, resulting in tumor development or cancer.
Calculate the molarity of 0.75 L of a solution containing 0.83 g of dissolved KCI. A 0.015 M B 0.75 M C 1.1 M D 6.2
Answer:
A 0.015M
Explanation:
Molarity, which refers to the molar concentration of a solution, can be calculated using the formula:
Molarity (M) = mole (n) / volume (L)
Based on the information provided in this question, the solution contains 0.83 g of dissolved KCI.
We can calculate the number of moles of KCl in the solution by using the formula:
Mole = mass ÷ molar mass
Where atomic mass of; K = 39, Cl = 35.5
Molar Mass of KCl = 39 + 35.5
= 74.5g/mol.
Mole = 0.83g/74.5g/mol.
mole = 0.01114
Approximately, n = 0.011mol
Hence, molarity = 0.011mol/0.75L
Molarity = 0.0146
Molarity = 0.015M

Assuming 320,000 individuals develop Lyme disease each year, what is the attributable risk for the cumulative incidence of Lyme disease that comes from tick bites, if 300,000 of the new cases reported each year come from tick bites?
A. 93.75%
B. 16.00%
C. 6.67%
D. 6.25%
Answer:
The correct answer is - A. 93.75%
Explanation:
In the given question, there are total individuals with disease = 320000
in which, Disease in exposed people = 300000
the Disease in unexposed in people = 20000
Therefore, the probability of disease in exposed people would be
= Disease in exposed people/the Disease in unexposed in people
= 300000)/320000
= 0.9375 * 100
= 93.75%

9. In squash, the allele for white fruits (W) is dominant over the allele for yellow
plant is crossed with a yellow-fruited plant and all the offspring are yellow, what are the possible
genotypes of the parents and the offspring?
a. parents
b. offspring
Answer:
parents: ww
offspring : ww
Explanation:
Purebred is the organism living beings that has their allele in their authentic form such as WW as tall and ww small and not heterozygous.
The combination of the two alleles of a gene determines the genetic trait of an organism.
Recessive alleles formed when the allele is masked by other alleles in the heterozygous condition always.
parents: ww
offspring : ww
The parents are homo-zygous ww and therefore their offspring will be homo-zygous ww.
What is purebred?A purebred organism is an individual that exhibits the same alleles for a given gene locus (w allele).
In this case, the individual is recessive homo-zygous for the trait color fruit (yellow).An individual that is dominant heterozygous will mask the expression of the recessive allele in offspring.In conclusion, in this case, the parents are homo-zygous ww and therefore their offspring will be homo-zygous ww.

Select the two correct statements. Select the two correct statements. All proteins will show different degrees of divergence because different species exhibit different patterns of behavior and have different metabolic pathways. All proteins will show the same degree of divergence because all cellular functions are essential to the survival of the organism.
Complete question:
Comparisons of amino acid sequences can shed light on the evolutionary divergence of related species. If you were comparing two living species, would you expect all proteins to show the same degree of divergence? Select the two correct statements.
All proteins will show the same degree of divergence because they are modified with the same rate of evolution. All proteins will show the same degree of divergence because different species experience the same selection pressure. All proteins will show different degrees of divergence because different species live in different habitats and experience different selection pressure.All proteins will show different degrees of divergence because different species exhibit different patterns of behavior and have different metabolic pathways. All proteins will show the same degree of divergence because all cellular functions are essential to the survival of the organism.All proteins will show different degrees of divergence because some cellular functions are more essential than others to the survival of the organism.Answer:
3) All proteins will show different degrees of divergence because different species live in different habitats and experience different selection pressure.
4) All proteins will show different degrees of divergence because different species exhibit different patterns of behavior and have different metabolic pathways.
Explanation:
All proteins will show the same degree of divergence because they are modified with the same rate of evolution. FALSE. All proteins will show the same degree of divergence because different species experience the same selection pressure. FALSEAll proteins will show different degrees of divergence because different species live in different habitats and experience different selection pressure. TRUE All proteins will show different degrees of divergence because different species exhibit different patterns of behavior and have different metabolic pathways. TRUEAll proteins will show the same degree of divergence because all cellular functions are essential to the survival of the organism. FALSEAll proteins will show different degrees of divergence because some cellular functions are more essential than others to the survival of the organism. FALSE.In this example, we are comparing different species, although we do not know how different they are. Changes in the proteins reflect the divergence between groups during evolution. Among different animals and plants, changes in proteins and their following maintenance can be associated with a group divergence and evolution.
The same proteins amino acid sequences in different species provide information about the divergence point between both species. Probably, the origin of genes and protein changes and the subsequent fixation of those changes by natural selection is the cause of most of the phenotypic variation observed between species. So, genes and proteins are subdued to selective pressures that vary according to the environment and the species.
In populations of the same species inhabiting different places with different environmental characteristics suffer changes that respond to their life habits. Proteins evolve in different degrees and take different routes, influenced by the selective pressures of the environment surrounding them. Ecological, behavioral, reproductive pressures, among others, vary between populations according to their own needs and produce changes that "model" the organisms when fixating. These changes are inherited generation after generation, leading to a divergence in the species.

Genes are made of proteins that code for nitrogen bases
DNA is made of carbohydrates that code for genes
Genes are made of DNA and code for proteins
Answer:
B
Explanation:
Genes are made of proteins that code for nitrogen bases. This is the description of genes. Thus, option C is correct.
What are genes made up of?Genes are made of DNA and code for proteins.This is because genes contain the genetic information needed for expression of characteristics in a living organisms. Therefore, genes contain DNA which is the genetic material. Genes are housed in chromosomes located in the loci.
DNA molecule forms a chromosome, and part of the same DNA molecule produce the genes on that is found in that chromosome. The information that is present in each gene codes the production of proteins and alsothe synthesis of RNA.
Genes are the molecules responsible for containing the genetic information that determines specific characteristics or features of an individual. Genes are housed in chromosomes, in specific locations called locus.
A DNA molecule forms a chromosome, and fragments of that same molecule form the genes on that chromosome. The information contained in each gene codes the synthesis of proteins, as well as the synthesis of RNA.
Therefore, Genes are made of proteins that code for nitrogen bases. This is the description of genes. Thus, option C is correct.

The function of glomerulus and Bowman's capsule of the nephron is to?
(A) reabsorb water into the blood
(B) eliminate ammonia from the body
(C) reabsorb salts and amino acids.
(D) filter the blood and capture the filtrate
Answer:
The function of glomerulus and Bowman's capsule of the nephron is to filter the blood and capture the filtrate (option D).
Explanation:
The set of glomerulus and Bowman's capsule is known as the renal corpuscle, and it is the structure responsible for the filtration of blood and its uptake as urine, which passes to the renal tubular system.
The renal glomerulus is the functional unit of the kidney, and is the structure responsible for filtering the blood that arrives through the renal capillary, to eliminate the waste products present in the blood.
Bowman's capsule surrounds the glomerulus and constitutes the second component of the filtration of blood plasma, in contact with the renal tubular system.
The other options are not correct because:
A. Reabsorb water into the blood occurs in the renal tubules.
B. eliminate ammonia from the body. Ammonia is one of the waste substances, converted to urea, that is eliminated by the kidney.
C. reabsorb salts and amino acids, occurs in the renal tubules.

Explain why a coyote might be grouped into Level 3 in one food web and Level 4 in another.
Answer:
This situation might happen depending on the ecosystem that it takes place in.
Explanation:
For example, in one ecosystem, where there are no serious predators trying to get the coyotes, they could be in a higher level because there is no immediate danger to them. However, in another ecosystem where there are predators trying to hunt them, they would be in a lower level because there, they are not at the top of the food web. Basically, it all depends on the ecosystem.
