Answer:

The carbon dioxide is one of the green house gases and mainly responsible for the increase of the earth's temperature. The plants uses the carbon dioxide for the photosynthesis process.

The plants that are exposed to the normal carbon dioxide can be used as a control in this experiment. Then the scientists will notice that if the amount of carbon dioxide is increased, does it show any positive or negative effects in the experiment.

You are conducting a twin study to estimate the heritability of a particular trait and have found that monozygotic twins have a
iogann1982 [59]

Answer:

The correct answer is "high heritability".

Explanation:

Concordance, is a term used in genetics to describe the probability that one of the twins have certain trait if his brother certainly has it. A high percentage of concordance, such as 75%, is translated into high heritability since monozygotic twins have identical genomic sequences. Additional information to determine heritability will be to study the exposure to similar environmental conditions, since environment can also affect the presence of certain traits.

8. Do plants need to carry out cellular respiration?
Leokris [45]

Answer:

Plants do resort to cellular respiration, wherein the products of photosynthesis are reunited to produce energy, which they have to do in order to convert the energy which is stored in the form of glucose into usable chemical energy.

When a potassium ion (K+) moves from the soil into the vacuole of a cell on the surface of a root, itmust pass through several c
goldfiish [28.3K]

Answer:

C. primary cell wall → plasma membrane → cytoplasm → vacuole.

Explanation:

Every molecule or particle which enters into a cell, it must pass through several cellular structure at different level means it also depends on the type of molecule like size, shape, and nature (characteristics). On the surface of root cell, potassium ion pass through the primary cell wall which is most outer layer of plant cell, then it passes the second layer called plasma membrane, in the plasma membrane cytoplasm is present and when potassium ion reaches the cytoplasm then it will enter into the vacuole present in cytoplasm.

In two or more complete sentences explain how to balance the chemical equation, KClO3 ⟶ KCl + O2 and include all steps.
Basile [38]
First of all you have to make both sides of the equation equal

KClO3 -------- KCL + O2

this is the way i would do it first

K - 1                K - 1
Cl - 1               Cl - 1
O - 3                O-2   From this we can see that the oxygen of both don't equal

So than from this we would need to find the common factor of the oxygen which is 6. So we would multiply 3 by 2 to get 6 as well as 2 by 3 to get 6.
The equation will now look like
K - 1                         K - 1
Cl - 1                        Cl - 1
O - 3 (2) = 6             O - 2 (3) = 6

so the final answere:

KCl2O3 --------- KCl + 3O2
