Explanation:

Answer:

A polar covalent bond will have the electrons shifted more towards one side or the other; a nonpolar bond will have evenly distributed electrons.

Explanation:

  The basis for a polar bond is that the electrons are shared unevenly. Some elements are more electronegative than others; that is, they pull harder on the electrons and tend to have more electrons around them. Following the periodic trends, Fluorine is the most electronegative element, so it will likely have the most dense area of electrons in a molecule. All this means that in a polar molecule, the electrons will be spread out unevenly along the lengths of the bonds as some elements will pull on them more than others will.

  Nonpolar molecules do not have to worry about differences in electronegativity, and so the electron density will be pretty evenly distributed along the entire molecule.

Hope this helps! :)

Answer:

Increasing substrate concentration also increases the rate of reaction to a certain point. Once all of the enzymes have bound, any substrate increase will have no effect on the rate of reaction, as the available enzymes will be saturated and working at their maximum rate.

The type of inheritance displayed by the illustration is incomplete dominance.

It is a kind of inheritance in which one of the two alleles of a gene exerts incomplete influence on the other allele.

For example, a cross of white and red flower plants yielding a plant with pink flowers. It means that the dominance of the red or pink allele is incomplete.

The same is applicable to a blue fish mating with a yellow fish to produce green offspring. A blend of the two colors occurred.

•Why do you feel the force of Earth's gravity?

Answer:

•Earth's gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body. That's what gives you weight. And if you were on a planet with less mass than Earth, you would weigh less than you do here.

Answer:

A water molecule consists of two hydrogen atoms bonded to an oxygen atom, and its overall structure is bent. This is because the oxygen atom, in addition to forming bonds with the hydrogen atoms, also carries two pairs of unshared electrons. All of the electron pairs—shared and unshared—repel each other.

Explanation:

Answer:

30mL is required

30ml of a 2.50 M hydrochloric acid solution is required to make 100.0 mL of a 0.750 M solution.

HCl is an acid which is made up of hydrogen and chlorine gas.

By the formula of dilution

M1V1 = M2V2

where V1 = 2.50 m

M2 = 100.0

V2 = 0.750 m

M1 × 2.50 m = 100.0 × 0.750 m

M1 = 30 ml

Thus, the M1 is 30 ml option a is correct.

The discrepancy in how much a person can lift on Earth and in Mars is due to the difference in the acceleration due to gravity in both planets.

Although, the physical Quantity, mass is always constant as it is a measure of the quantity of matter in a body. The weight on the other hand is a function of the acceleration due to gravity and hence is different in different planets.

On this note, it follows that a person can carry 270kg mass on earth and 440kg mass on Mars.
