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.
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.

How do sprinters receive enough energy to sprint?
Answer:
As the fastest way to get ATP for muscle contraction, the phosphagen system is the predominant energy system used for races lasting up to 10 seconds. The muscles of sprinters like Maurice Greene, who has run 100 meters in 9.79 seconds, are great at producing ATP via the phosphagen system.

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.
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.

Why are only some plants sexually produced?
Answer:
Explanation:
This is because some plants grown by seeds which is as a result of fertilization or fusion of the male and female gametes. Seeds carries the genetic information. These sexual reproduction lead to formation of offsprings which have different genetic information from the parent or that are genetically different from the parent and these help them to survive or thrive and adapt in various environment.

I NEED HELP ASAP! Which of the following is true of variation?
Select one:
a.
It is necessary for natural selection.
b.
It exists in almost all populations.
c.
It is caused by mutations and sexual reproduction.
d.
All of the choices are correct.
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.
Therefore, the correct option for this question is D.
