As demonstrated by the carbon cycle, matter on Earth is generally A. released into space once it reaches the atmosphere. B. recycled continually through the spheres of the Earth. C. created and destroyed by the basic life processes of organisms. D. absorbed into the Earth's core where it can no longer be used.
Answers
Answer:
B
Explanation:
As demonstrated by the carbon cycle, matter on Earth is generally recycled continuously through Earth's regions. So, the correct option is B.
What is Carbon cycle?The carbon cycle is defined as the biogeochemical cycle by which carbon is exchanged between the biosphere, the pedosphere, the geosphere, the hydrosphere, and the Earth's atmosphere, where carbon is the main component of organic compounds, as well as carbon deposits such as limestone which is a major component of many minerals.
Photosynthesis, decomposition, respiration and combustion from the atmosphere to plants and living things are the steps of the carbon cycle. For example, carbon is a pollutant in the atmosphere in the form of carbon dioxide.
Therefore, the correct option is B.

Based on the information in the table, which of the following describes alleles I and IB?
A. The IA and I alleles show sex linkage.
B. The IA allele is recessive to the IB allele.
C. The IA allele is dominant to the IP allele.
D. The 1A and I alleles show codominance.
Answers
Answer: The answer is D.) codominance.
According to the table IA and IB are showing codominance character. If a person has both IA and IB alleles and has blood group AB, hence option D is correct
What is a blood group?The blood group is determined by the gene which produces, surface antigens on the red blood cells and antibodies present in the plasma.
In the blood group having i gene does not produce any sugar, while the IA gene produces sugar which results in the A blood group having antibodies against another blood group which is anti-B, and a person having the IB gene produces blood group B and has antibodies anti-A.
If having both IA and IB, it shows codominance, and having blood group AB does not produce any antibodies, while ii produces O blood group and antibodies anti-B and anti-A.
Therefore, IA and IB, show codominance.

O A only if the mutation occurs in the sex cells B. only if the mutation occurs in the y-chromosome C. only if the parent has an acquired mutation in the autosomal chromosome D. only if both parents do not have the mutation in the sex cells
Answers
Answer:
O A only if the mutation occurs in the sex cells
Explanation:
Mutations can be defined as genetic changes that occur in the DNA sequence of the genome of an organism. Mutations can be classified into two main types: 1-somatic mutations, which occur in somatic cells that form the body of the organism, and 2-germ-line mutations, which occur in sex cells or gametes (i.e., egg and sperm cells). Only germ-line mutations can be passed on to offspring and it occurs when a mutated gamete (either a sperm or an egg) comes together to form a diploid (2n) zygote.

Insulin is a protein that maintains homeostasis in the amount of sugar in the blood. When there are high levels of sugar in the blood, cells in the pancreas generate more insulin and release it into the blood. This causes muscle cells and fat tissue to absorb sugar. When there are low levels of sugar in the blood, the production of insulin is slowed.
What is the most likely cause of the phenomenon described?
1. Glucose has a chemical reaction with blood cells to create insulin.
2. The expression of the insulin gene is regulated by blood glucose concentration.
3. Pancreas cells have more copies of the insulin gene than other cells.
4. The body has a surplus of insulin stored in the pancreas and releases it when needed.

The incidence of MRSA, methicillin-resistant Staphylococcus aureus, has increased in the last twenty years. The rise of MRSA strains is significant, and MRSA infections are often developed within the hospital system rather than outside of them. In terms of how MRSA strains developed, evaluate each statement below. Choose the statements that accurately describe how MRSA strains occurred. You may select ALL that apply.
A) Individuals that are admitted to the hospital are likely already carrying MRSA infections.
B) Hospitals treat patients with MRSA with drugs that cause the Staphylococcus aureus to mutate more rapidly.
C) Hospital systems provide a mechanism for extreme selection pressure with sterile technique and heavy use of antibiotics.
D) Staphylococcus aureus can transmit genetic components containing the methicillin resistance to offspring and other members of the population.

Being a narrow-spectrum antibiotic it was discovered in the 1960's.
The drug is resistant to the B lactam antibiotic. The hospital thus provides it with extreme care and can be used for genetic treatment.

The statements that accurately describe how MRSA strains occurred are: Individuals that are admitted to the hospital are likely already carrying MRSA infections. Hospital systems provide a mechanism for extreme selection pressure with sterile technique and heavy use of antibiotics. The correct options are A, C, and D.
These claims draw attention to crucial elements involved in the emergence and dissemination of MRSA strains.
It is possible for someone to carry MRSA before entering a hospital, increasing the likelihood that an infection would take place there (Statement A).
Hospital systems, with their emphasis on sterile procedures and heavy reliance on antibiotics, produce a setting with high selection pressure that favours the survival and spread of MRSA strains (Statement C).
Staphylococcus aureus can also pass on genetic elements that are resistant to methicillin to offspring and other population members, aiding in the propagation of resistant strains (Statement D).
Thus, the correct options are A, C, and D.

Answer:
C. Organisms use meiosis to make reproductive cells.
The statement 'organisms use meiosis to make reproductive cells' is TRUE of meiosis (Option C).
Meiosis is a type of reductional cell division by which a parental cell produces four (4) daughter cells having half of the genetic material.Organisms of sexual reproduction use this type of cell division to produce germinal (gametes) sex cells.During fertilization, two germinal gametic cells fuse to produce a cell (zygote) with a normal amount of chromosomes.In conclusion, the statement 'organisms use meiosis to make reproductive cells' is TRUE of meiosis (Option C).

Answer:
all of them are correct
Variations are essential for natural selection to occur. It exists in almost all populations. It is caused by mutations and erotic reproduction. Hence, all of the choices are correct.
What do you mean by Mutation?A Mutation may be defined as the sudden, stable, and inheritable changes in the genetic material of an organism.
Variations provide the favorable traits that induce natural selection. Variations are caused by mutations, gene flow, and erotic reproduction. It exists in all life forms present on the earth.
Sometimes, variations decide the relative fitness of an organism and thus natural selection occurred.

If you cross two heterozygous Yy pea plants, what proportion of the offspring will be the dominant color yellow?
Answers: 50%, 25%, 75%, 0%
Answers
Answer:
The possible genotypes are: YY, Yy, Yy, yy
The proportion of the offspring with the dominant color is 75%
The cross two heterozygous Yy pea plants, the proportion of the offspring will be the dominant color yellow is the possible genotypes are: YY, Yy, Yy, yy. The proportion of the offspring with the dominant color is 75%. Thus, option C is correct.
What are the cross between heterozygous?If you cross a heterozygous organism with another heterozygous organism, pair two Tt and Tt. Below is a punnet square to show the result:
T t
T TT Tt
t Tt tt
This actually means that you have two heterozygous recessive and one homogenous dominant and one homogenous recessive. Genetics has known as the study of the heredity as well as the variation of the inherited the characters and the genetic properties and the organism's feature and the characteristics. It has also known as the branch of biology that deals with the study of genetic variation, genes, and the heredity in the organisms.
Therefore, the cross two heterozygous Yy pea plants, the proportion of the offspring will be the dominant color yellow is the possible genotypes are: YY, Yy, Yy, yy. The proportion of the offspring with the dominant color is 75%. Thus, option C is correct.
