Answer:
Nitrogen is found in soils and plants, in the water we drink, and in the air we breathe. It is also essential to life: a key building block of DNA, which determines our genetics, is essential to plant growth, and therefore necessary for the food we grow.

Which of the following is an example of evolution?
A. Plants colonizing inland areas after developing vascular systems that can hold and transport water.
B. An organism developing immunity to a disease after surviving it.
C. A Chameleon changing color when entering a different environment.
D. An organism dying because it is not adapted to its habitat.
Answer: B
Explanation: because it adapt to its environment to survive
The development of an organ system like a vascular system over a long period of time in plants is an example of evolution. Thus option A is correct.
What is evolution?Evolution is a series of events that have taken place in several years to make the species more advanced for the environment due to the introduction of multiple mutations in the genetic sequence.
During evolution, plants have gained the genetic mutation that codes for the vascular system which provide support and transports water in plants. So option A is correct.

What about the structure of DNA allows it to copy itself?
A. It is held together mostly by hydrogen bonds, which are easy to open for replication
B. It has enzymes built into the helix that make a copy when needed.
C. It is double stranded, so each side serves as a template for a new strand.
D. DNA is not copied, it is only passed down through each generation.
Answer:
C. It is double stranded, so each side serves as a template for a new strand
Explanation:
The structure of DNA is double stranded, so each side serves as a template for a new strand. The correct option is C.
What is DNA replication?Replication is the procedure by which the DNA of the genetic code is copied in cells.
Before dividing, a cell must duplicate (or replicate) its a whole genome so that each eventually results daughter cell has its own entire genome.
The DNA replicates itself multiple times during the process of replication. It is a biological polymerization that goes through the steps of commencement, elongation, and termination.
The reaction is catalyzed by enzymes. The main enzyme in the process of replication is DNA Polymerase.
DNA replication occurs in eukaryotic cells' interphase nuclei. At the S-stage (synthesizing) of the cell cycle, DNA replication occurs prior to mitosis.
Thus, the correct option is C.

How green is green energy?
Answer:
Green energy is important for the environment as it replaces the negative effects of fossil fuels with more environmentally-friendly alternatives. Derived from natural resources, green energy is also often renewable and clean, meaning that they emit no or few greenhouse gases and are often readily available.

The genetic code contains thousands of genes. Each gene codes for a
specific
A. fatty acid
B. amino acid
C. polypeptide
D. polysaccharide
Answer:
amino acid
Explanation:
The genetic code contains thousands of genes. Each genetic code represents a specific amino acid. Hence, option B is correct.
What is Genetic code?A genetic code represents a set of three-letter that are a combination of nucleotides known as codons. Each of them correlates to a particular amino acid.
Amino acids are the molecules that combine to form protein which serves as the base of life. Genetic code is translated into a sequence of amino acids with the help of a codon table.
Codon is a sequence of three nucleotides that form a unit of genetic code in DNA or RNA molecules.
Therefore, the amino acid is represented by each genetic code. Thus, option B is correct.

The ________ is the amount of times a cell can replicate before dying, and in humans it is about ______. A. Hayflick limit, 1000 B. Hayflick limit, 50 C. Division constant, 1000 D. Division constant, 50
Answer:
The answer is B. Hayflick limit, 50.
Explanation:
The Hayflick Limit is a concept that helps to explain the mechanisms behind cellular aging. The concept states that a normal human cell can only replicate and divide forty to sixty times before it cannot divide anymore, and will break down by programmed cell death or apoptosis.
Leonard Hayflick developed the concept while at the Wistar Institute in Philadelphia, Pennsylvania, in 1965. In his 1974 book Intrinsic Mutagenesis, Frank Macfarlane Burnet named the concept after Hayflick. The concept of the Hayflick Limit helped scientists study the effects of cellular aging on human populations from embryonic development to death, including the discovery of the effects of shortening repetitive sequences of DNA, called telomeres, on the ends of chromosomes.

Explain how in glycolysis that the splitting of one glucose molecule results in 4 ATP but there Is only a net gain of 2 ATP.
Answer:
Explanation:
During glycolisys in cytoplasm, first step involves adding two phosphates to glucose molecule. This step requires the use of two ATP molecules. The next step is splitting 6 carbons glucose into two 3 carbons pyruvates. This step produces 4 ATPs and 2 NADHs. However, since we used up two ATPs during the initial phosphorylation, the net gain is only 2 ATPs
