The answer is Polymer

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.

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.

Answer:

D. Reflected vs Absorbed

Explanation:

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.

Answer:

1. The first statement is true because water movement takes place until it reaches an equilibrium.

2. The second statement is false because the concentration inside the cell will be greater until water moves inside the cell.

3. The third statement is true because solute concentration is high outside.

4. The fourth statement is true because it loses water in a hypertonic solution.

A temporary change in the ability of some enzymes to bind with their substrate. The correct option is B.

Thus, Animals can be categorized into two groups: those that keep a steady body temperature despite varying environmental temperatures and those that have a body temperature that fluctuates with the environment.

Ectotherms are animals that do not regulate their body temperature but instead depend on outside energy to accomplish it.

The name "cold-blooded" has been applied to this category, but it might not be appropriate for an animal living in the desert with a fairly warm body temperature. Animals known as endotherms can experience temperature extremes but rely on internal sources to maintain their body temperature.

Thus, A temporary change in the ability of some enzymes to bind with their substrate. The correct option is B.

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.

Researchers wanted to do research because they thought normal cells spontaneously became cancerous cells.

The first immortal human cells to be generated in culture were from Henrietta Lacks. They are also known as Henrietta's cells. They were crucial in the creation of the polio vaccine. In the early space flights, they went up to investigate what would happen to cells in weightlessness.

Her cells have since been employed in numerous significant scientific breakthroughs, such as cloning, gene mapping, and in vitro fertilization.

After the rumor spread that Henrietta's cells took over many other cell cultures in research labs scientists wanted to do research, because they thought that normal cells are converting into cancerous cells.

Answer:

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.

Ecological succession is the process of change in the species structure of an ecological community over time. It is a process by which an ecological community undergoes more or less predictable changes following a disturbance or the initial colonization of a new habitat.

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.

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.
