What's the quickest way for an ant to go from the ground to the tree trunk?

1 answer:

6 0

The quickest way for an ant to go from the ground to the tree trunk is by walking straight towards the tree and climbing the tree trunk. Ant will walk straight if it is guided by the pheromone trail left behind by the other ants.

The ant first decides to explore the area for food and threats before taking a decision to walk away from its current location, i.e, the ground. The ant then starts to climb the bark of the tree to reach a higher ground. It does so by leaving a pheromone trail behind. This pheromone trail helps in guiding the other ants towards a possible food source.

Isolating all of the RNA out of an organism, subjecting it to reverse transcriptase, and then cloning all of the resulting DNA i

Lisa [10]

Answer:

The answer is C.

Explanation:

The example process given in the question is describing the creating of a cDNA Library. cDNA or Complimentary DNA is copy of the DNA that is taken from a messenger RNA (mRNA), which is what is done with the reverse transcriptase. And the process described as cloning the resulting DNA into plasmids is the part where the library is created. The resulting DNA is put into host organisms and stored there for further investigation or use.

I hope this answer helps.

Plants in the rainforest contribute to precipitation there through transpiration. Please select the best answer from the choices

zheka24 [161]

The statement above is true. Plants contribute to precipitation through the process of transpiration. This is because this process is a naturally occurring behavior of plants where water evaporates from the plants' leaves that are carried through plants from the roots.

Which trophies level contains more energy: strophic level of herbivores or a trophies level of carnivores? Why?

Elden [556K]

Herbivores. The eat directly from the producers. 10% of the producer's energy goes to herbivores, while only 10% of the 10% energy the herbivores had goes to carnivores.

How do humans (and other animals) rely on the products of photosynthesis?

baherus [9]

Answer:

Like plants, humans and other animals depend on glucose as an energy source, but they are unable to produce it on their own and must rely ultimately on the glucose produced by plants. Moreover, the oxygen humans and other animals breathe is the oxygen released during photosynthesis.

aksik [14]

Answer:

For sample A, A=17.7 %, T=17.7 %, G=32.30%, C=32.30%

For sample B, A= 28.9%, T=28.9%, G= 21.10%, C= 21.10%

Explanation:

The composition of nitrogenous bases in DNA is calculated using the suggestions proposed by the results of the experiment performed by Erwin Chargaff.

He found that in a DNA sample the composition of purine to pyrimidine is 1:1. This indicates that the amount of purine equals pyrimidine. This can be presented as purines + pyrimidines= 100. Also, adenine binds thymine and cytosine binds guanine.

In the given question,

For sample A

A= 17.7 %, Therefore, thymine will be = 17.7 %,

A+T= 35.40%

Now, G+C=100- 35.40%

G+C= 64.60%

content of G= 64.60/2= 32.30%

content of C= 32.30%

For sample B

T=28.9%, A will be= 28.9%

A+T= 57.80%

G+C=100-57.80%

G+C= 42.20%

Thus content of G will be= 42.20/2=21.10

content of C= 21.10%

Thus,

For sample A, A=17.7 %, T=17.7 %, G=32.30%, C=32.30%

For sample B, A= 28.9%, T=28.9%, G= 21.10%, C= 21.10%
