The correct answer is B
The genetic codes language in all living organisms is the same. This is to say that the molecules of life namely DNA and RNA share the same make up in all living things .
There are five types of nucleotides in nature which are the building blocks of RNA and DNA and these are the same in all living organisms . These nucleotides are Adenine, Thymine, Guanine, Cytosine and Uracil.
According to base pairing rules, in all DNA molecules Adenine will always pair with Thymine while Guanine will always pair with Cytosine.
This rule is the same with RNA except that here Thymine is replaced with Uracil. Otherwise the base pairing rule applies in all living organisms, that is to say it is universal.
Answer:
A- Schemas
Explanation:
Schemas are used to categorize information and draw conclusions, based on patterns and the relationships between them. In this case, you see your new roommate looking and behaving the way we believe an intellectual person would and you automatically assume that he/she is intellectual.
Answer:
Option 1, a charged end and a noncharged end
Explanation:
Complete question
If a small droplet of ordinary fat is suspended in water, the fat molecules form a "ball of spaghetti" with no particular orientation. But if a droplet of phospholipid molecules is put in water, all the molecules point outward, toward the water. Phospholipids are forced into this orientation because phospholipids have _____
- a charged end and a noncharged end
- three fatty acid molecules, all pointing in different directions
- two fatty acid molecules pointing in different directions
- both a saturated fatty acid and an unsaturated fatty acid
- two charged ends
Solution
The structure of phospholipids consists of the following groups and molecules –
a) A glycerol molecule
b) Fatty acids (2 in numbers) – It is hydrophobic as it is uncharged and non polar in nature
c) Phosphate group (with alcohol) – It is hydrophilic as it is negatively charged and polar in nature.
When the phospholipids are placed in water, the molecule rearranges itself in a way that the hydrophobic head face inside and the hydrophilic head face outside thereby forming micelles.
Hence, option 1 is correct
The correct option is (d) The early solar system had large amounts of water; so, the oldest objects in the solar system should also be abundant in water.
The statement that answers the scientific questions in the form of scientific data that supports the claim is called a scientific claim. There is need for the justification of the claim. The scientific claim here is The early solar system had large amounts of water and the justification to the claim is water is found in all the primitive bodies like the comets and the asteroids and in many dwarf planets like ceres. There are many evidences that shows that there are abundant amount of water in our solar system.
