Answer:

Because of its high electronegativity.

Explanation:

Fluorine has ability to pull the electron from the lithium because of its high electronegativity.

We know that as we move from left to right in periodic table the number of valance electrons in an atom increase. The atomic size tend to decrease in same period of periodic table because the electrons are added with in the same shell. When the electron are added, at the same time protons are also added in the nucleus. The positive charge is going to increase and this charge is greater in effect than the charge of electrons. This effect lead to the greater nuclear attraction. The electrons are pull towards the nucleus and valance shell get closer to the nucleus. As a result of this greater nuclear attraction atomic radius decreases and electronegativity increases. AS lithium is present on left side of period 2 and fluorine is present on right side of same period. Fluorine is more electronegative while lithium is more electropositive thus fluorine pull the electron from lithium when they combine and form anion while lithium loses its valence electrons and form cation.

Answer:

A)glucose is broken down into two pyruvate molecules

The statement below correctly describes the process of glycolysis, glucose is broken down into two pyruvate molecules. The correct option is A.

Glycolysis is the process in which glucose is broken down to produce two molecules of pyruvic acid, which also releases energy. This process can be carried out without the help of oxygen, thus an anaerobic reaction. This process is carried out in the cytoplasm.

For the cell to use as energy, glycolysis results in a net gain of two pyruvate molecules, two ATP molecules, and two NADH molecules. Following the conversion of glucose to pyruvate, the Krebs Cycle is connected to the glycolysis pathway, where additional ATP will be produced to meet the energy requirements of the cell.

Therefore, the correct option is A.

Explanation:

Bone remodeling occurs by the remodeling units osteoblast which is bone deposition and osteoclast which is Bone resorption.

Bone deposition is the process that involves the deposition of minerals in bone tissues which takes place due to the process of osteoblast mainly. the bone deposition is possible in three ways when

- there is an increase in blood calcium.

- there is an increase in mechanical stress.

- decrease in parathyroid hormone

Osteoclast cause the degrade of bone tissue by releasing calcium ion from bone tissue which required opposite conditions than osteoblast that are -

- there is a decrease in blood calcium.

- there is a decrease in mechanical stress.

- increase in parathyroid hormone

A decrease in blood Ca++ concentration causes the parathyroid gland to release PTH, PTH results in osteoclasts to degrade bone tissue which releases Ca++ into the blood. A high level of Ca++, calcitonin results in calcium deposition into the bone.

Complete the Concept Map to compare the locations and remodeling functions of osteoblasts and osteoclasts, and explain how hormones and physical stress regulate bone remodeling.

Bone remodeling involves osteoblasts which is enhances bone deposition and osteoclasts which enhance bone resorption.

Bone remodeling involves the processes by which the bone tissue is remodelled by the action of the osteoblasts which is enhances bone deposition and osteoclasts which enhance bone resorption.

Bone deposition is the process by which bone tissues ate mineralized by means of the osteoblast.

Bone deposition occurs through three possible ways:

Osteoclast are involved in the degradation of bone tissue producing opposing effects to that of the osteoblast as follows:

The parathyroid gland releases PTH in response to low bllod calcium.

PTH induces osteoclasts to degrade bone tissue which releases calcium ions into the blood.

The increase in blood level of calcium ions induces calcitonin to increase calcium deposition in the bones.

Active Transport

Explanation:

Active transport is the movement of dissolved molecules into or out of a cell through the cell membrane, from a region of lower concentration to a region of higher concentration. The particles move against the concentration gradient , using energy released during respiration.

The similarities between facilitated diffusion and active transport by a protein pump are firstly facilitated diffusion and active transport are two membrane transport mechanisms, which transport molecules across the plasma membrane, secondly transmembrane proteins are involved in both facilitated diffusion and active transport.

The differences between them are facilitated diffusion takes place down the gradient of concentration. active transport takes place toward the gradient of concentration. Facilitated diffusion is a passive method and needs no energy. An active method is an active transport.

What do you understand by facilitated diffusion?

"Facilitated diffusion is the passive movement of molecules along the concentration gradient. It is a selective process."

What do you understand by active transport?

"Active Transport is defined as a process that involves the movement of molecules from a region of lower concentration to a region of higher concentration against a gradient or an obstacle with the use of external energy."

What is a protein pump?

"Protein pump– a kind of protein that is capable of pumping out compounds that could pose a threat to the cell."

Explanation:

The cuticle in the plants minimizes the water loss or transpiration from leaves. The correct option is A.

Transpiration is the process by which water vapor is lost via the stomata of plants. When the weather is very hot, the plant's loss of water vapor cools it down, and moisture from the stem and roots moves upwards or is 'pulled' into the leaves.

The evaporation of extra water from stomata in plant leaves is known as transpiration. It is necessary for some upward movement of water in plants. It aids in the regulation of plant temperature.

To transpire, water vapor must diffuse through this motionless layer from the stomata to the atmosphere, where it will be removed by moving air. The cuticle present in the waxy leaves prevent excess transpiration.

Thus, the correct option is A.
