The leading cause of limited water supplies is _______. a. low precipitation b. overuse c. limiting use d. government

Answers

Answer 1
Answer:

Answer: a. low precipitation

Precipitation is the amount of rainfall an area or a biome receives. It is the chief source of water for water bodies available for human use like lakes, rivers, ponds, groundwater. The amount of rainfall depends upon the vegetation growing in an area. The trees and plants transports water through the process of transpiration that adds up to the water cycle. Lack of vegetation can affect normal water cycle and can limit the occurrence and amount of rainfall. The lack of proper rainfall will limit the volume of water in water bodies and hence, will limit the water supply for use.

Answer 2
Answer:

The leading cause of limited water supplies is overuse. Therefore, the correct option is B.

An important issue in water scarcity is the overuse of water resources. Human activities, including domestic water use, industry, and agriculture, can use up more water than is permanently available in a given location. With population growth and economic expansion, the demand for water increases, putting pressure on the already available water resources.

Limiting use is one way of managing water resources, although it is not the main cause of resource depletion. Government management and regulation of water resources are important, but they are not the root cause of scarce water supplies.

Therefore, the correct option is B.

Down’s syndrome results from people having an extra copy of chromosome 21 in their cells as shown here. People with Down’s syndrome have both a lower IQ and a shorter life expectancy than those without Down’s syndrome. This is an example of

Answers

The answer is trisomy 21.

Trisomy 21 is a condition in which an extra copy of chromosome 21 is present. Instead of two chromosomes 21 in a cell, there are three chromosomes. This is a consequence of a failure of chromosome 21 to separate during the gamete development. Thus, an egg cell or a sperm cell will have two instead of one chromosome 21 and after a cross with normal gamete cell, a zygote will have three chromosomes 21.

D) changes in chromosomes leading to changes in cell processes.

Which of the following best describes the interaction between Earth’s crust and living organisms?a.Raw materials essential for life are cycled through Earth’s crust.
b.Fossil fuels are a valuable energy source for the biosphere.
c.The continental crust allowed the evolution of life on land.
d.The crust recycles the organic materials in sedimentary rock.

Answers

The best answer is A. Raw materials which are essential for life are cycled through the Earth's crust. The crust is the uppermost layer of the Earth. In this layer many types of rocks are found.  The crust is the also coined as the home of life since it has its own systems of mineral recycling which is essential for life here on earth.

Exposure to cosmic rays, X-rays, ultraviolet rays, and radiation from radioactive substances may promote?

Answers

Exposure to cosmic rays, X-rays, ultraviolet rays, and radiation from radioactive substances may promote diversity among organisms. The correct option is C.

What is diversity?

All the different types of life that are present on Earth are referred to as biological diversity or biodiversity. Three layers of biodiversity can be identified and quantified: species, genetic, and ecosystem diversity.

As high-frequency (high-energy) ionizing radiation, x-rays, and gamma rays contain sufficient energy to ionize (take the electron from) an atom or molecule.

Exposure to cosmic rays, X-rays, ultraviolet rays, and radiation from radioactive substances cause mutation, and mutation cause change in genes which cause diversity.

Therefore, the correct option is (C) diversity among organisms.

Potatoes are also known as tubers and they commonly make up most of the carbohydrate needs that the body can get from food. It is made up of parenchyma tissue that makes the plant have the ability of cloning and low metabolic activity. They are commonly used for experimentation as a “model tissue” because of these characteristics.
