Answer:

Your answer would be A.)

Explanation:

Archaea that live in salty environments are known as halophiles. Archaea that live in extremely hot environments are called thermophiles. Archaea that produce methane are called methanogens. Archaea are known for living in extreme environments, but they also can be found in common environments, like soil.

Halophiles are organisms that are able to live in environments with high saline concentrations. The name comes from halo, greek for salt, and phile, greek for loving.

Meiosis reduces chromosome number and rearranges genetic information. Explain how the reduction and rearrangement are accomplish

Alisiya [41]

Answer:

Explanation:

Meiosis is a form of cell division that occurs in the sex cells of organisms. It ensures the reduction of a diploid cell to an haploid cell to allow for the formation of a diploid zygote after fertilization (contribution of both parents haploid sex cells to give a diploid zygote). Thus, this process is very essential and important.

The reduction is accomplished by 2 divisions after the duplication of chromosomes

- first division: separation of homologous pairs of chromosomes (this reduces the total in half)

- second division: separation of sister chromatids of a chromosome.

The rearrangement in meiosis occurs by crossing over/genetic recombination.

This is the exchange of genetic material between homologous pairs of chromosome bringing about a rearrangement and genetic variation

An example of a chromosomal abnormality that arises as a result of defects in this process is the Down Syndrome which is caused by a nondisjunction of the chromosomes 21 pair in a sex cell.

This condition produces offsprings that have some characteristic facial features, short stature etc

The diagram shows three steps in the carbon cycle.

Bumek [7]

Answer:

A. Cellular respiration

C. Photosynthesis

Explanation:

There are two main processes occurs in the carbon cycle i.e. cellular respiration and photosynthesis. Plants absorb carbondioxide gas from the atmosphere through small openings called stomata. The carbondioxide enters the leaves and combine with water produces glucose and oxygen. Glucose is stored in different parts of plant whereas some oxygen is used by the plant and the remaining oxygen is releases in the atmosphere while on the other hand, in cellular respiration, glucose is broken down to produce energy in the form of ATP, carbondioxide gas and water.

In the graph, a sample of water is heated from 40 degrees Celsius to 100 degrees Celsius. Which statement correctly describes th

Vladimir [108]

(Next time please insert a picture of The graph regarding to your question)

Answer: The answer is (A)

Explanation:

QR- Liquid Only

RS- Phase Change Liquid-Gas

ST-Gas Only

This graph does not begin in the solid phase of water. It begins at 40 degrees Celsius in the liquid phase. Plateaus are phase changes. In this case, it’s a phase change from liquid to gas.

A paramecium reproduces by dividing into two daughter cells. Which statement is true of the daughter cells?

Cerrena [4.2K]

This statement giving a clue that there is asexually reproduction (may be binary fission) taking place and the progenies in asexual reproduction are genetically similar to parent cell. So answer is A.
