Answer:  Vegetative propagation is an a s exual method of plant reproduction that occurs in its leaves, roots and stem.

Answer:

regeneration of new plant from the vegetative part or organ of the parent plant is called vegetative propagation vegetative propagation is used full to separate the plant in wider region mother plant get favourable condition if then colonized to the reason by vegetative propagation the offspring adapted

1 NATURAL VEGETATIVE PROPAGATION-

BY ROOT -

the interact root of several Woody plants such as guava sisoo grow just below the soil produce advantages but should just below the soil produce but should develop from this bird which give rise to new plant

BY STEM -

stamp is the source of natural vegetative reproduction in several plants modification or found in stem to perform vegetative propagation

a Runners- the weak stem of creep forward on the soil that downwardly from node axillary bud are present in the axils of scale leaves node

b s ucker - rise time in similar to runner but it is underground its main stem grow upward and develop advantages root from underground

c offset- the thick and fleshy runner of hydrophytes plant is called offset

BY LEAVES

Titan plant develop adventirious bud on their leaves this word after separating from Mother plant give rise to new plant

BY BULBILS

they are fleshy but which are produced in the axils of leaves in the auxiliary Bud

GRAFTING

it is the most common method of vegetative reproduction in this method variety of shame spices can be converted into plant of better variety in the technique of trade off to plant are joined in such portion of one part called stock is joint with another plant is called scion

BUDDING-

it is the superior and modern method of plant propagation in this method but of plant are superior varieties grafted in the stem of plant in variety after making oblique you cut up to the bark of stem after fue with this but join with plant as result formed on the new plant

LAYERING-

the method of inductor root formation the branches while they are still attached to a mother plant is called layering

CUTTING -

any part of plant root stem or leaf which has the power to develop itself into a new plant after separating from the mother plant is called cutting

We can confirm that Increased ethanol production is not a consequence of bioenergy use.

This has to do with the fact that there would be no need for increased production of ethanol when using bioenergy. This is due to the fact that biomass naturally produces ethanol and that most bioenergy does not rely on ethanol to be created.

Therefore, we can confirm that Increased ethanol production is not a consequence of bioenergy use.

Convective clouds cannot go high enough to produce showers and visibility also greatly reduced due to the accumulation of dust and smoke particles.

Frontal Inversions are the inversions that is caused by a shallow "cold air" blowing in under warmer air. An inversion traps air pollutants, such as smog, close to the ground.

So we can conclude that convective clouds cannot go high enough to produce showers and visibility also greatly reduced due to the accumulation of dust and smoke particles.

Prophase

Explanation:

parent chromosomes are condensed into an x shape

Answer:

The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage). The stages G1, S, and G2 make up interphase, which accounts for the span between cell divisions.

Animal hiding-holding still response follows the reflex arc sequence. The fourth event in the series is option B) signaling by efferent PNS neurons.

When the animal receives the stimuli, it responds to them. In the case of hiding-holding still response, the animal might freeze due to motor inhibition that reduces excitatory signals.

The reception and reaction to stimuli follows the reflex arc sequence.

The reflex arc refers to the sequence of events since the body receives an external stimulus until it reacts.

The correct answer is B) signaling by an efferent PNS neurons.

All statements are true about the energy and trophic levels. So, the correct option is D. None of the above.

Trophic levels are the levels of energy transfer from lower to higher levels.

There are five levels of trophic level.

The lower level contains autotrophs or producers. And the uppermost level contains big animals or tertiary consumers.

The energy level decreases on going to the higher levels because some amount of energy always lapses as entropy.
