How can gravity's role in tectonic plate motion be described?

diamong [38]

In most trees and wildflowers, one root, the taproot, is more prominent than the other fibrous roots. The taproot is usually relatively large in diameter and extends more deeply than the plant's other roots, and often has additional lateral roots.

Oduvanchick [21]

Answer:

Allopatric speciation

Explanation:

Allopatric speciation is a type of speciation that takes place when a group of species are divided into two different groups which are separated from each another. In allopatric speciation, a geographic barrier such as a water body (river) or a mountain range forms and prevents the species from mating with each other. As the species are separated into two groups, each of them develops its own distinct traits based on the demands of their unique environment or the inherited traits of the group that are passed on to offspring.

Why are non native species with invasive traits a threat to ecosystem

liubo4ka [24]

<u>Answer:</u>

Any ecosystem is designed with a particular necessity that drives it's entire organisms that is residing in the particular ecosystem. Invasion by other species would deprive the initial nutrients that are contained in an ecosystem for it's native species.

This in turn would gradually make the native species extinct. The ecosystem contains all the nutrients that are enough for its residents and it is perfectly balanced by the nature, but invasion of a non-native species would break the natural balance and create deficit.

777dan777 [17]

Answer:

I am a basophil.

Further information:

Basophil:

Basophils are a type of white blood cell. Basophils are the smallest common of the granulocytes, representing about 0.5 to 1% of circulating white blood cells. Yet, they are the major type of granulocyte.

Function of basophil:

They are accountable for inflammatory reactions during immune response, as well as in the development of acute and chronic allergic diseases, including anaphylaxis, asthma, atopic dermatitis and hay fever. They also yield compounds those co-ordinate immune responses, including histamine and serotonin that induce inflammation, heparin that stops blood clotting, although there are less than that found in mast cell granules.

Basophils may present in many specific types of inflammatory reactions, specially those that cause allergic symptoms. Basophils have anticoagulant heparin, which prevents blood from clotting too rapidly. They also have the vasodilator histamine, which promotes blood flow to tissues.

Structure of Basophil:

Basophils comprise large cytoplasmic granules which vague the cell nucleus under the microscope when stained. However, when unspotted, the nucleus is visible and it usually has two lobes. The Mast cell which is another granulocyte has very like in appearance and function. Both cell types store histamine, a chemical that is secreted by the cells when inspired. However, they arise from different branches of hematopoiesis, and mast cells usually do not circulate in the blood stream, but instead are located in connective tissue. Similar to all circulating granulocytes, basophils can be carried out of the blood into a tissue when we need it.
