Inessa [10]

Answer:

The question lacks the illustrative diagram, the diagram has been attached as an image.

The correct answer, according to the picture is A.

Explanation:

All cells undergo division (mitosis or meiosis). Meiosis reduces the chromosomal number of the daughter cells by half. According to the question, The female species of Myrmecia pilosula ant has diploid cells total number of 2 chromosomes.

At the metaphase stage of meiosis I, homologous chromosomes (similar but non-identical chromosomes received from each parent) aligns at the center/equator of the cell called METAPHASE PLATE. This alignment is done when spindle fibres attach to the kinetochores of the chromosomes.

Option A in the diagram depicts this arrangement of homologous chromosomes in the centre of the cell. Note that, each chromosome has replicated to form SISTER chromatids held together at the centromere. These chromosomes will be pulled apart in the next stage (Anaphase).

Option B depicts only one replicated chromosome

Option D depicts separation of sister chromatids (only one chromosome)

Option E depicts separation of sister chromatids of two chromosomes which occurs in the Anaphase of meiosis II

An example of an adaptation to prevent water loss in plants is

Masja [62]

One example can be the needle shaped leaves.

In desert areas, there are not much water sources. So basically, any drop of water is precious. To help prevent water loss of plants, for example cactus has very thin leaves that are needle shaped. Or some even don't have any leaves. This can reduce the surface area of leaves and thus reduce the water evaporating to the outer environment.

Another example also shown on cactus is that they have very thick waxy cuticle. It can also prevent water from evaporating from the stem. So that's why you see the stem is very shinny.

Cellulases are enzymes capable of breaking down cellulose, releasing molecules of glucose. to which category of organic macromol

erastovalidia [21]

Cellulose belongs to carbohydrates.

Cellulose is classified as a carbohydrate, a polysaccharide, as they are formed of the glucose monomers chain. It is the prime component in the walls of the cells of plants, assisting the plants to remain upright and stiff. Humans cannot digest cellulose due to the absence of cellulase, however, it is essential in the diet as fiber.

However, the animals like sheep, cows, and horses can digest cellulose that is why they can acquire nutrients and energy they require from the grass.
