Answer:

Explanation:

Question 1. Sexual reproduction in plants occurs by the production of a gametophyte. Gametophyte are haploid multicellular organisms that act as sperm and eggs act in humans. Gametophytes are part of the sexual reproduction life cycle of plants, producing a zygote that generates a new plant.

Examples of asexual reproduction include: mitosis, binary fission, budding, fragmentation, spore formation and vegetative propagation.

What is the graphical representation of age structure known as?
gayaneshka [121]

Answer:

The graphical representation of the age structure is known as age pyramid (option D).

Explanation:

The age pyramid or more properly called population pyramid groups all the individuals of a population, distributing them by age and sex. The name is due to the fact that, in general, the bar graph resembles a pyramid.

The age groups are distributed in the pyramid by age from lowest (bottom) to highest (top), with the sexes forming the sides of the pyramid.

In emerging countries the population is relatively young, which makes the base of the pyramid wide, narrowing as it moves up to the upper age groups.

    <u><em>Age group</em></u><em>, </em><u><em>age graph</em></u><em> or </em><u><em>age scale</em></u><em> do not correspond to the population graph where the age and sex structure of a population are expressed.</em>
