The centripetal force is the force that's causing the object to accelerate on a circle. There are three forces acting on the string: gravity (downward), friction (resisting acceleration but negligible), and tension (force the string applies to the key). The only force that is relevant is tension, and therefore, your answer is A, tension.

What happens when you drink to much salt water
garri49 [273]

Answer:

when you drink to much salt water you dehydrate quickly

Explanation:

Consuming very salty water, like the kind in the ocean, may introduce more salt to your body than it's capable of processing. Your body attempts to flush the excess by inducing urination, pushing your kidneys into overdrive. Because you must excrete more water than you consume to get rid of the extra salt, you may dehydrate quickly.

Mice collected from the Sonoran desert have two phenotypes, dark(D) and light (d). The mice shown below were collected in a trap
lesantik [10]

Answer:

Frequency of individuals with recessive trait(dd)= 71.4 %

Explanation:

Please see the attached.

In the image it is clear that there are total 26 mouse out of which 6 are dark colored.

Since dark color allele is dominant, these  6 dark colored mouse will have genotype either  DD or Dd

The individuals with genotype "dd" will be of light color.

Number of light colored mouse = 21 -6 = 15

Frequency of individuals with recessive trait(dd)

= \frac{15}{21} * 100\\

= 71.4 %

Monomers are the building blocks of which of the following? SELECT ALL THAT APPLY
kirill [66]

Monomers are molecules whose linkage between them form polymers.

<h3>What are monomers?</h3>

Monomers are molecules that have a low molecular mass.

<h3>Characteristics of monomers</h3>

  • When many monomers come together through chemical bonds they form a polymer, which is a macromolecule.

  • Natural monomers allow the formation of biomolecules found in living beings.

  • Carbohydrates, for example, are macromolecules that are created from the bond established by monosaccharides (monomers).

Therefore, we can conclude that polymers, in short, are chains of monomers -generally joined by covalent bonds-.
