Answer:
92 molecules
Explanation:
DNA or Deoxyribosenucleic acid is polynucleotide made up of several nucleotides containing the genetic information of an organism. In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA, tightly coiled many times around proteins called histones to support its stucture.
Human cells, like myself, contains 23 pairs of chromosomes (46 chromosomes in total). Each pair coming from each parent. Each chromosome is formed by two strands of DNA held together by hydrogen bonds forming the DNA double-helical structure. These two DNA strands form a base pair, which is a unit of two nucleotide bases bound to each other by hydrogen bonds. According to the complementary base pairing rule, Adenine (A) pairs with Thymine (T) while Guanine pairs with Cytosine (C).
Since there are 46 chromosomes in a diploid human cell and each chromosome consists of 2 DNA strands, then, there are 46 × 2 = 92 strands/molecules of DNA in each human diploid cell.
Answer:
B
Explanation:
Im sure this is false because i have the same question before
Exergonic is the term in the passage that is most likely be used only in a scientific context.
<u>Explanation:</u>
The term Exergonic is used in a scientific context in the given passage. The chemical reactions takes place either absorbing or releasing energy to its environment in which the reactions takes place. This is due to the breaking or the formation of chemical bonds. It mainly depends on the bond's strength.
When energy is given to the environment in which it takes place then it is called as exoergonic reaction. This occurs due to high strength of the chemical bond that is formed. When energy is absorbed from the environment in which the reaction takes place, it is known as endergonic. The bond that is formed will be weaker and not stronger.
I think it is D.... Light and heat from the sun do impact the biosphere.
Amount of Precipitation
the savanna is a desert so it rarely rains, whereas the rain forest gets lots of rain.
