Which two kinds of information can scientists gather using radar?
makkiz [27]

The correct answers are C. Amount of rainfall, and D. Wind speed.

Explanation

Radars are instruments that were created by humans to detect objects, people, places, among others, through signals. Radars are devices used in different fields such as war, aviation, climatology, geography, among others. One of the best known is the Doppler radar, which is a climatological tool that is used to detect the intensity, size, quantity, and direction of rainfall. Likewise, rainfall is influenced by the direction and speed of the wind, data that can also be obtained using this tool. One of the purposes for which this object was created was the early detection of natural phenomena related to rains, and winds such as hurricanes, electric storms, hail, among others. Therefore, the two objects that scientists can obtain with a radar are C. Amount of rainfall, and D. Wind speed.

just olya [345]

Answer:

1. New chromosomes remain attached to cell membrane - Both

2. Proteins check for errors - Both

3. Starts at one place - Prokaryotes

4. Proceeds in two directions - Both

5. Copies of DNA condense into chromosomes that separate - Both

6. Starts at many places - Eukaryotes

Explanation:

The difference between prokaryotic and eukaryotic DNA replications is associated with the origins of replication, that is, the locations where replication starts. While in eukaryotic DNA, the origin of replication occurs in several places along the strands of DNA, replication in prokaryotic DNA has a unique origin of replication.

docker41 [41]

Answer:

25%

Explanation:

In sheep, the allele for belly fur (A) is dominant to the allele for no belly fur (a). A mother with the genotype Aa and a father with the genotype Aa produce an offspring. What is the percent chance that the offspring will have NO belly fur?

Allele A is dominant over allele a.

Genotype of mother = Aa

Genotype of father = Aa

Crossing Aa and Aa:

Aa   x   Aa = AA, 2Aa, and aa

Since A is dominant over a, both AA and Aa have belly fur.

Hence, the ratio of the offspring with belly fur to those without belly fur is 3:1.

Percentage of the offspring without belly fur is 25%.
