I believe that the correct match will be;
Prominences- A
Sunspots - B
Solar flares - C
Convection -D
Prominence is a large, bright feature extending outward from the Sun's surface. Prominences are anchored to the Sun's surface in the photosphere, and extend outwards into the Sun's hot outer atmosphere, called the corona.
Sunspots are darker, cooler areas on the surface of the sun in a region called the protosphere. Solar flares are large eruptions of electromagnetic radiation from the sun lasting from minutes to hours.

Dinobryon is a species of protozoa that reproduces asexually. How is it better for the survival of the species for the protozoa

MakcuM [25]

Answer:

A. They do not use up any energy finding mates.

Explanation:

The asexual reproduction consists of one parent which are same to each other while on the other hand consists of two parent that produced unique.

For species survival, the reproduction of protozoa asexually rather than sexually could be better when they don't use much time and energy for determining the mates

Therefore in the given case the correct option is A.

What are the adaptive features of animal in rainforest

mylen [45]

Answer:

<h2>Many animals have adapted to the unique conditions of the tropical rainforests. The sloth uses camouflage and moves very slowly to make it difficult for predators to spot. The spider monkey has long, strong limbs to help it to climb through the rainforest trees.</h2>

Candace is wanting to be sure that she is doing what she can to prevent the spread of disease. Which of the following should she

Temka [501]

Answer:

Take medicine to destroy the germs.

Avoid contact with other people's bodily fluids.

Eat healthful foods such as fruits and vegetables.

Explanation:

For the spread of disease, there is usually a host who bears the infectious agent, the agent exits through a port of exit from the host, is carried by a mode of transmission, then enters a susceptible second host through a port of entry. To stop transmission, stopping the infectious agent can include;

Stopping the agent from leaving the host through port of exit – e.g quarantine the patient
Curtailing the modes of transmission – e.g killing disease vectors
Protecting the ports of entry in the susceptible second potential host – e.g by improving immunity

Suppose a geneticist isolates two bacteriophage mutants. One mutation causes clear plaques (c), and the other produces minute pl

Nesterboy [21]

Answer:

The mentioned parental types are c+m- and c-m+. Thus, the recombinants will be c+m+ and c-m-.

Now, the given distance between c and m is 8 map units. Thus, the recombinant frequency is 8% or 0.08.

The total recombinants from 1000 plaques will come out to be 80,

Thus, the recombinants of each type will be 40.

Total parental type will be 920, and therefore, each parental type count will be 460.

Thus, expected c+m- = 460, expected c-m+ = 460, expected c+m+ = 40 and expected c-m- = 40.

svlad2 [7]

Answer:

1. DNA

2. Nucleus

3. mRNA

4. Transcription

5. Nucleus

6. mRNA

7. Cytoplasm

8. Ribosome

9. Translation

10. anti-codons

11. codon

12. amino acids

13. protein

Explanation:

Deoxyribonucleic acid or DNA hold all the instructions that make up an organism. It determines the physical structure and even the function of the different cells that make up all organisms.

The DNA are all stored in the NUCLEUS of cells. Typically, eukaryotic cells have a nucleus except red blood cells. The nucleus has a nuclear envelope that keeps the DNA stored inside but it has nuclear pores that allows it to interact with the cytoplasm.

In order for DNA to be replicated, it needs to be turned into messenger RNA, otherwise known as mRNA. The mRNA decodes the DNA in order for the cell to use the code. The process is called transcription.

Transcription is done within the nucleus. Before the cell can understand what to do with DNA, mRNA transcribes to know what information it needs to produce specidic proteins.

Once transcription is done, it will then bring the information out of the nucleus and into the cytoplasm. The cytoplasm is the viscous gel-like solution that holds the organelles of the cell. In the cytoplasm you have ribsomes.

Ribosomes is where protein synthesis takes place, this is why it is called the protein factory of the cell. It is a molecule that is made up of ribosomal RNA, which direct the chemical processes involved in protein synthesis. For protein synthesis to happen, it will need another type of RNA, which is the tRNA.

tRNA is transfer RNA and they translate the mRNA sequence into proteins. tRNA have amino acids attached to it.

Each 3 bases of the mRNA are collectively known as codons. These codons correspond with specific tRNA that hold the anticodons. These anticodons code for specific amino acids that they also hold.

When they pair up, the tRNA drop off the amino acid which form a chain with the other tRNA amino acids that complete the code. These chain of monomers then make the protein specific to the DNA code that was copied in the beginning.
