Mario and several friends spend a day at the beach. While watching the ocean waves crashing to shore, Mario wonders how much of

the world's water is contained in different types of bodies of water such as oceans, lakes, and rivers. He decides to research the percentage of Earth's water found in different locations. Which does his research reveal? Multiple choice question. A) Less than 3 percent of Earth's water is freshwater containing no salt. B) The ice caps located at both poles contain 30 percent of Earth's water. C) Fifty percent of Earth's water is in oceans and the glaciers at the poles. D) Ninety percent of Earth's water is in lakes, rivers, and groundwater.

Answer:

A

Explanation:

The correct answer here would be that <u>less than 3 percent of Earth's water is freshwater containing no salt.</u>

<em>Generally speaking, about 71 % of the earth is made up of water. Out of this percentage, approximately 97 % is found in the oceans with less than 3 % being freshwater. About 68.7 % of the freshwater is locked-up as glacier and ice, 30.1 % is groundwater, while the remaining 1.2 % represents surface and other forms of freshwaters which include ground ice and permafrost, lakes, atmosphere, rivers, swamps and marshes, soil moisture, and the freshwater in living organisms. </em>

The correct option is A.

Which of the following lists has the steps involved in the whole genome shotgun approach to Sequencing in the correct order? 1.
Paha777 [63]

Answer:

5,2,3,1 and 4.

Explanation:

Whole genome shotgun sequencing is the method in the genetics that are used to sequence the whole DNA fragments. Different DNA sequencing methods are chemical sequencing and Sanger sequencing.

The different steps that are involved in the whole genome shotgun sequencing are as follows. The DNA is isolated and  broken DNA with the help of the restriction enzymes. The genomic fragments are inserted into the cloning vector for its multiplication. These fragments are then transformed into the E.coli with the cloning vector. The sequence assembly is important step in the sequencing. Than the sequencing of the cloned fragments are done to find the sequence of the whole genome.

Thus, the correct sequence is 5,2,3,1 and 4.

Which type of deposition creates sandbars?<br><br> A glacial<br> B river<br> C wave<br> D wind
Ede4ka [16]

The correct answer is option C, that is, waves.  

Waves take place at shorelines and are inhibited by the rock walls, dunes, plants, sandbags, and raised structures. The deposition of sand mediated by waves produce beaches and sandbars. The waves continuously erode and shape the coastline.  

The tides, winds, storms, and at certain occasions earthquakes results in the formation of waves. The sandbars also known as trough bars, are formed at the point of breaking of the waves.

cestrela7 [59]
<span>The research shows that the relationship between estrogen and verbal tasks is negative while it is positively correlated with spatial tasks. This correlation shows that, like in other animal studies, there could be some sort of organizing of the brain that goes on related to the level of sex hormones in the body.</span>
