Answer:

Option D

Explanation:

Mutations are changes that occur in the DNA sequences as a result of environmental factors like exposure to some certain chemicals or radiation that can be passed down to the offspring and this increases genetic variations which can prevent permanent fixation of an allele.

Does the process of glycolysis require an input of energy? provide specific evidence from model 1 to support your answer.
borishaifa [10]

Yes. In the beginning, glycolysis requires 2 ATP molecules. One ATP allows for the phosphorylation of the glucose molecule to fructose-6-phosphate and another phosphorylation to fructose-1, 6-biphosphate. The fructose-1, 6- bisphosphate is then cleaved into two glyceraldehyde-3-phosphates that then enter the energy generating part of the glycolysis biochemical reaction.

What implications need to be considered when creating environmental policies?
butalik [34]

Answer:

Is the benefit worth the cost?

Explanation:

Environmental policies application has to lead to some economic cost.

When coming up with this policies, the effect that this policies shall have towards environmental protection shall be considered.

The cost and economic effect that this policies shall cause should also be looked at.

If a policy causes insignificant change towards environmental protection and at the same time the costs are too high, then the policy should be dropped.

If a policy has got significant impact and costs less, the it should be taken.

Which symbol in a chemical equation separates the reactants from the products?<br> 11 T<br> AI +
IrinaVladis [17]

Arrow symbol  →

Explanation:

The arrow symbol in a chemical equation separates the reactants from products.

A chemical reaction is process in which chemical changes leads to the formation of products from reactants.

The arrow symbol → is used to separate the reactants from products

                                ⇆ shows reversibility of the reaction

                                ↑ indicates that gas is given off as product

When a singly ionized potassium ion moves through a channel in the membrane passing from the outside to the inside, what is the
Korolek [52]

The magnitude of the work done by the electric field of the membrane is <u>W = 1.28 × 10⁻²⁰ Joules</u>.

We start with the necessity to take into account a value for the voltage present there in order to solve this problem by first considering that the membranes have two layers, one internal and one external, each responsible for producing a potential difference between the two levels.

As a result, in order to find a solution, it is necessary to take into account the potential difference between the two surfaces. In this instance, we'll assume a particular value for the load, but the recipient is free to substitute a different value if they prefer.

The product of the potential difference and the charge is used to define the work that an electric field performs. The charge of the potassium ion will be equal to that of its electron, so,

q = 1.6 × 10⁻¹⁹ Coulombs

Then the Work would be:

W = Vq

Here,

v = Potential difference

q = Charge

The 80mV potential difference we will have is quantified as follows:

W = (80mV (1V/1000mV))( 1.6 × 10⁻¹⁹ C)

W = 1.28 × 10⁻²⁰ Joules is the amount of work that the membrane's electric field has produced.

Describe the chemical make up and type of bonding found in water molecules?
andre [41]
Water molecules consist of 2 Hydrogen and 1 Oxygen atom. They are bonded by a polar covalent bond, meaning the electrons shared by the covalanet bonds are not evenly distributed. Oxygen is more electronegative than Hydrogen and will pull the electrons from its bonds with Hydrogen closer to itself. Thus results in a partial positive dipole on the Hydrogen of the water molecule and a partial negative dipole on the Oxygen of the water molecule. These partial charges allow water to hydrogen bond with one another through a process called cohesion.
