Answer:

The correct answer will be option-A

Explanation:

The centrifugation of the blood shows that 45% of the blood is composed of the cellular content and 55% blood plasma or liquid.

Erythrocytes or red blood cell constitute for about 41% of the total blood cells which transports the oxygen by binding it to the haemoglobin. The presence of haemoglobin is the reason the cell appears red which cause the color of the blood to appear red.

The remainder of the cell is white blood cells or leukocytes which play important role in providing the defence mechanism against the pathogen.

Thus, option-A is the correct answer.

Roman55 [17]

Answer:

A) rely on protection and resources supplied from the maternal plant.

Explanation:

The embryo is a structure formed after the fusion of the male gamete and female gamete. A diploid zygote is formed after cellular division forms the embryo in the female gametophyte and therefore is considered the diploid tissue.

The embryo requires the nutrients for growth and absorb them from the surrounding female gametophyte structure like endosperm in the angiosperm. The embryos grow and form the sporophytic structure.

Thus, Option-A is correct.

What is an invasive species?
Serga [27]

Answer:

An invasive species is an organism that causes ecological or economic harm in a new environment where it is not native.

Explanation:

Invasive species can harm both the natural resources in an ecosystem as well as threaten human use of these resources. An invasive species can be introduced to a new area via the ballast water of oceangoing ships, intentional and accidental releases of aquaculture species, aquarium specimens or bait, and other means.

Invasive species are capable of causing extinctions of native plants and animals, reducing biodiversity, competing with native organisms for limited resources, and altering habitats. This can result in huge economic impacts and fundamental disruptions of coastal and Great Lakes ecosystems.
