Answer: Negative

Explanation:

This is called an anion. Whenever an atom gains a electron, it becomes negative. When an atom loses an electron, it becomes postitive. Positive atoms are called cation.

After an ionic bond is formed, the charge of the atom that gained an electron will be negative.

An ionic bond, also widely recognized as an electrovalent bond, is a category of interconnection established by the electrostatic attraction of ions with opposing charge in a chemical substance.

When the valence (outermost) electrons of one atom are permanently transferred to another atom, a bond is formed.

An ionic bond is formed between a metal and a nonmetal, whereas a covalent bond is formed between two nonmetals.

An ionic bond is formed by the complete transfer of electrons from one atom to another. When an atom loses one or more electrons, it becomes a cation, or positively charged ion.

When an atom gains one or more electrons, it becomes an anion, a negatively charged ion.

Thus, the atom is negatively charged as it gained electron.

B

Explanation:

evaporation and precipitation are the parts of the water cycle, the others are not

Answer:

So in the case of a plant, a higher light intensity means more packets of light called “photons” are hitting the leaves. As you rise from low light intensity to higher light intensity, the rate of photosynthesis will increase because there is more light available to drive the reactions of photosynthesis.

Explanation:

If you continue to increase the intensity of light that a plant receives, what happens? The rate of photosynthesis increases with light intensity. The rate of photosynthesis decreases with light intensity. The rate of photosynthesis increases and then levels off.As light intensity increases (distance between lamp and plant decreases) the volume of oxygen (or the rate of bubble production) increases. This indicates that the rate of photosynthesis increases with light intensity.

B) abiogenesis

Abiogenesis is one of the modern evolutionary theories on how life originated. It used to refer to the now-discredited hypothesis of spontaneous generation. It was once believed that complex living organisms such as mice, maggots, etc. could arise spontaneously from nonliving matter.

Cesium (Cs) in particular can surrender its valence electron quite conveniently than lithium (Li). In fact, the ease with which the alkali metals give up an electron varies as follows: > Cs > Rb > K > Na Li is the most likely to lose an electron, followed by Cs and Li.

In chemistry, reactivity is the impulse that causes a chemical substance to undergo a chemical reaction, either on its own or in conjunction with other materials, resulting in the release of energy.

The reactivity of an element is a measure of how easily it will combine with other elements to form substances.

The number of electrons in an atom's outermost shell determines its reactivity. Noble gases have low reactivity so even though their electron shells are complete.

Cesium (Cs) in particular can more easily surrender its valence electron than lithium (Li).

In fact, the alkali metals' ability to give up an electron varies as follows: > Cs > Rb > K > Na Li has the highest probability of losing an electron, followed by Cs and Li.

Thus, these are some elements that is more difficult to take electrons away from tin or Gallium.

I believe that it is D.

Explanation:

If ice caps are melting, and polar bears use the ice flows to get their food, then the polar bears can't use the ice to get food. so, the polar bears most likely are expanding their diets to adapt to their surroundings. So, polar bears are probably moving off the sea ice and eating other foods.

1. b. Dehydration synthesis

2. a. Hydrolysis

Explanation:

Hydrolysis is the process where water is used to break chemical bonds. Dehydration synthesis is the reverse reaction, where a bond is formed resulting in the loss of water from the molecule, so a water molecule is generated as a product.

That means that dehydration synthesis produces water, and hydrolysis uses water.

Answer:

b. Dehydration synthesis gives out  water as a product.

a. Hydrolysis reaction uses water as a reactant.  

Explanation:

b. Dehydration synthesis can be defined as, formation of  larger molecule from small reactant, followed by loss of water from the reaction.

a. Explanation: Hydrolysis, it is the reaction in which compound is interacted with water which results in the degradation of that particular compound.

Answer:

A cell may vary the rate of an enzyme controlled reaction by making more/less or degrading more/less.

Explanation:

A cell may vary the rate of an enzyme controlled reaction by making more/less or degrading more/less. Several factors affect the rate at which enzymatic reactions proceed include post translational modifications, substrate concentration, cofactors, temperature, pH, locations. The shape and structure of the enzyme will change as the pH value of the reaction medium changes.

A cell may vary the rate of an enzyme controlled reaction by:

According to the given question, we can see that we need to show how a cell can vary the rate of a reaction which is controlled by an enzyme.

As a result of this, we can see that there are different ways through which a cell may control the rate of reaction in an enzyme controlled state which are by the level of degradation with time.

Answer:

varyatio of somthing and multiple varitons of it

Explanation:

The two ways that variation can be described are meiosis and evolution, because in the meiosis process, sexual reproduction occurs, and in the evolution process, changes in animals are seen and variation is observed.

When sexual reproduction occurs, there is variation seen because in meiosis genes cross over and recombinate, resulting in variation in offspring from their parents, but it is absent in asexual reproduction that is caused by mitosis or binary fission because here there is no variation in the offspring and the parents. The process of evolution introduces variation because, along with environmental factors, the animal genes are influenced too.

Hence, the two ways that variation can be described are meiosis and evolution, because in the meiosis process, sexual reproduction occurs, and in the evolution process, changes in animals are seen and variation is observed.

Answer:

D. Reflected vs Absorbed

Explanation:

Answer:

Please find the description and it's pair below:

Homologous chromosome pairs - DIPLOID

Designated N - HAPLOID

Designated 2N - DIPLOID

Has one member of each

homologous chromosome pair - HAPLOID

Includes gametes - HAPLOID

Includes somatic cells - DIPLOID

Heart and liver cells - DIPLOID

Sperm and Egg cells - HAPLOID

Explanation:

1. Diploid organism is an organism with two sets of chromosomes, with each set contributed by each male and female parent. Chromosomes from the male parent is found side by side with chromosomes from the female parent to form HOMOLOGOUS CHROMOSOME PAIR in a diploid organism. Diploidy is denoted by 2N, where N represents number of one set of chromosomes. Diploid cells include somatic or body cells such as heart and liver cells.

2. Haploid organisms are organisms that contain one set of chromosome, formed as a result of meiotic division of diploid cells. Hence, a haploid cell contains one member of each homologous chromosome pair. Haploidy is denoted by N, meaning number of one set of chromosome. Haploid cells include gametes or sex cells such as sperm and egg cells.
