When does the mitotic spindle attach to the kinetichore?

Answers

Answer:

The Prometaphase.

Explanation:

Typically in biology the prometaphase is overlooked. It is between the prophase and the metaphase, and is the exact point in which the mitotic spindles attach to the kinetochores. Metaphase, which occurs directly afterwards, is when the chromosomes are lined up to be split and pulled towards opposite sides of the cell.

The relationship between the amount of energy available for use and the amount of entropy in a food chain differs between trophic levels. why would the amount of entropy increase from one trophic level to another in a food chain or energy pyramid? a. the available energy from one trophic level to another increases b. energy is lost at each level as heat, which increases randomization c. the amount of biomass decreases from one trophic level to another d. the available energy at each level may either increase or decrease, creating randomization

Answers

The amount of entropy in a food chain differs between trophic levels the correct option is "B" energy is lost at each level as heat, which increases randomization.

What is the 10 per cent law of energy?

The 10% Rule indicates that when energy is flowing in an ecosystem from one trophic level to the next, only ten per cent of the energy will be passed on. A trophic level is the position of an organism in a food chain or energy pyramid.

Thus, energy is lost at each level as heat, which increases randomization.

How could the origin of organisms such as dinosaurs, whose gait allowed them to move without compressing their lungs, have led to emergent properties?.

Answers

The ability of dinosaurs to move without compressing their lungs helped them to effectively produce more energy requited for other emergent properties.

What was the advantage of being able to breathe with lungs?

The lung is a special organ in the body of higher animals such as mammals and birds whose function is for gaseous exchange.

Possession of the lung gave an evolutionary advantage to organisms that have lungs as it enabled them to occupy various habitats on land as they could effectively use oxygen to produce energy.

Therefore, the ability of organisms such as dinosaurs to move without compressing their lungs helped them to effectively produce energy for other emergent properties.

Why don't birds get electrocuted when they land on electrical wire?
And, Why is water wet?

Answers

Answer:

Birds don’t get electrocuted when they land on power lines because the lines are grounded to distant devices, and the current never passes through the birds, because their electrical potential is greater than the ground. If the grounding is removed, then the birds will die.

The reason why The water gets wet Is due to the existence of two forces:"forces of cohesion"which are the forces that have attached to the water particles (H2O) and the"forces of adhesion"are those that are manifested when the water molecules come into contact With another surface.

Explanation:

Answer: They're Not Good Conductors. Birds are able to sit on electrical power lines because the electrical current essentially ignores the bird's presence and continues to travel through the wire instead of through the bird's body. A bird's body is not a good conductor of electricity.

Wetness is our description of what we feel when we put our hand in water. Saying water is wet is like saying that wood is hard or fire is hot. Sensory receptors on our hand send information about the water to our brain. But my theory is Water is dry. The reason is becuase, if water touches water, it doesnt get more wet, so its dry.

Explain the life cycle of gymnosperms in detail.

Answers

Answer:  In gymnosperms, the gametophyte generation takes place in a cone, which forms on the mature sporophyte plant. Each male gametophyte is just a few cells inside a grain of pollen. Each female gametophyte produces an egg inside an ovule.

Hope this helps!

Answer:

The male cones release pollen into the air. The wind then carries the pollen to the female cones. The pollen gets stuck in a sticky liquid produced by the ovule. Sperm from the pollen fertilize the egg in the ovule. The ovule then develops into a seed. When the seed is mature, it is dispersed. If conditions are good, the seed grows into a seedling, which grows into a tree. The tree produces cones, and the cycle begins again.

d.) G2
e.) G1

Answers

Answer:

Interphase (A.K.A. S Phase)

Explanation:

Hope this helps.

Most of the cell's growth and activity occurs in the S-phase of mitosis. During the S-phase, a cell grows in size and genetic material duplicates. Thus, the correct option is A.

What is Mitosis?

Mitosis is the division of cell in which the DNA or the genetic content of the cell remains constant from one generation to the next generation. Mitosis consists of interphase and M-phase. During the interphase, cell prepares for division while in the M-phase the cell undergoes division.

The S phase of a cell cycle occurs during the interphase after the G1 phase, before the M-phase, and it is responsible for the replication of DNA. In this stage, the genetic material of a cell is doubled before it enters the M-phase, allowing enough amount of DNA to be split into the two daughter cells.

Therefore, the correct option is A.
