FromTheMoon [43]

Options for the question have not been provided. They are as follows:

A) The single intact parcel would have a smaller amount of edge than the 20 separate parcels.

B) The isolated hectare plots increase the ability of individuals to disperse from one habitat to another.

C) The separate 1-hectare plots are less vulnerable to edge effects.

D) The large plot will create more inbreeding in many species.

Answer:

A) The single intact parcel would have a smaller amount of edge than the 20 separate parcels.

Explanation:

In the given case, 20 hectares of land has been allocated to natural habitat. This means that natural flora and fauna will flourish here without any human interference. In this situation it is better to have an intact 20 hectares area at one side of the land, rather than having 20 separately spread out 1 hectare areas. This is because having one large piece of land at one side will reduce the edge effect.

Edges occur where two different habitats meet. While edges can be beneficial when it comes to natural habitats because the boundary habitat increases overall biodiversity, it can be detrimental when the edges are due to human settlements. It will be difficult to avoid human interference as the natural habitats are scattered among human settlements. Each individual plot will also get less area due to which it will be difficult for all the species to accommodate comfortably. Many animals can venture out in search of food which can be dangerous to both animals and humans. It is better to have a big separate land at one corner so that everyone can survive peacefully.

ehidna [41]

Explanation:

All living organisms need nutrients to survive. While plants can obtain nutrients from their roots and the energy molecules required for cellular function through the process of photosynthesis, animals obtain their nutrients by the consumption of other organisms. At the cellular level, the biological molecules necessary for animal function are amino acids, lipid molecules, nucleotides, and simple sugars. However, the food consumed consists of protein, fat, and complex carbohydrates. Animals must convert these macromolecules into the simple molecules required for maintaining cellular function. The conversion of the food consumed to the nutrients required is a multistep process involving digestion and absorption. During digestion, food particles are broken down to smaller components, which are later absorbed by the body. This happens by both physical means, such as chewing, and by chemical means.

One of the challenges in human nutrition is maintaining a balance between food intake, storage, and energy expenditure. Taking in more food energy than is used in activity leads to storage of the excess in the form of fat deposits. The rise in obesity and the resulting diseases like type 2 diabetes makes understanding the role of diet and nutrition in maintaining good health all the more important.

weqwewe [10]

Answer:

b. where movement occurs through arm-over-arm swinging.

Explanation:

Brachiation is a form of locomotion observed in some species of animal that are adapted to arboreal (tree living) life.

<em>This type of locomotion involves the swinging of arms and the suspension of the body to move from trees to trees.</em>

Animals that exhibit brachiation usually have modified body structure with long forelimbs/hook-like fingers and a highly mobile shoulder joints. Examples of such animals include gibbons and siamangs.

The correct option is b.
