A simple diagram of a DNA molecule is shown below. Which of the following is represented by X?
(photo above)
Answer:
From the diagram X = base pairs
Explanation:
Genetic information stored within DNA is used for growth, reproduction, and cell repair. DNA, deoxyribonucleic acids, are long-chain, helical macromolecules made of specific sequences of covalently bonded monomers called nucleotides.
Nucleotides comprise:
a 5-Carbon deoxyribose sugar, one nitrogenous base (adenine, guanine thymine, and cytosine) and a phosphate group.Nitrogenous bases cause nucleotides to form hydrogen bonds with other nucleotides as base-pairs. The four types of bases each make the nucleotides Thymine and Cytosine (pyrimidine bases) along with Guanine, and Adenine, (purine bases). In base-pair formation, Adenine forms double bonds with Thymine, and cytosine forms triple bonds with guanine.

Human activities can have an impact on natural disasters. t or f
Answer:
True
Explanation:
Take Hurricanes for example, As global warming keeps getting worse, We are going to keep having more and more since the ocean will stay warmer longer which is showing right as this moment. Earthquakes, Humans can interfere with this say they are mining near tectonic plates and they have an explosion occur, This can cause a major or minor earthquake to occur as the plates shift among one another which can cause violent shaking and maybe even huge faults to occur in the earth's surface

Explain how mutations can alter a DNA strand and ultimately a protein structure. Make sure to include point mutation, frameshift mutations, insertion, deletion, substitution, and silent mutations.
Answer:
By changing a gene's instructions for making a protein, a mutation can cause the protein to malfunction or to be missing entirely. When a mutation alters a protein that plays a critical role in the body, it can disrupt normal development or cause a medical condition

If a father has type A blood and the mother has Type AB blood, they would NOT have a child with which of the following blood types?
AB
A
B
O
Answer:
If a father has type A blood and the mother has type AB blood, they cannot have a child with blood type O, although depending on the father's genotype, they may not have children with a B blood type either.
Explanation:
Blood type is determined by the presence or absence of surface antigens A and B, which is genetically determined and establishes the pattern of inheritance.
Alleles that define the presence of antigens A and B are co-dominant, while the absence of antigens - as in blood type O - is a recessive trait.
Type A contains antigen A and its genotype can be A|A or A|O. Type B contains the B antigen, whose genotype can be B|B or B|O. Blood type AB contains both antigens and a single genotypic expression A|B Type O blood lacks surface antigens, with genotype O|O.The father with blood type A can have two genotypes, A|A or A|O, which raises 2 possible scenarios:
1. Father A|O with mother A|B
Alleles A O
A A|A A|O
B A|B B|O
In this case there is no chance of having a child with blood type O, 50% chance of having children with blood type A, 25% B and 25% AB.
2. Father A|A with mother A|B
Alleles A A
A A|A A|A
B A|B A|B
50% chance of having a child with blood type A and 50% with blood type AB. In this case there is no chance of having children with blood type O or B.

Glucose molecules bond together through DEHYDRATION SYNTHESIS to produce starch.
WHAT IS DEHYDRATION SYNTHESIS?
Dehydration synthesis is the process whereby larger molecules are formed from the coming together of smaller molecules accompanied by the release of water.HOW STARCH IS FORMED FROM GLUCOSE?
Glucose is a monosaccharide i.e. contains one sugar unit while starch is a polysaccharide i.e. contains many sugar units. Glucose molecules come together to form an α-1,4 glycosidic linkage. This joining process that eventually forms starch results in the loss of water molecule, hence, it is called DEHYDRATION SYNTHESIS.Glucose molecules (C6H12O6) bond together through DEHYDRATION SYNTHESIS to produce starch.

In plants, yellow pea color (Y) is dominant over green pea color (y). Two heterozygous plants (Yy) are crossed. Which of the following results supports Mendel’s Laws
1.All of the yellow offspring are heterozygous for color.
2.all of the offspring have genotype Yy.
3.All of the offspring are yellow.
4. The offspring could be yellow or green.
Answer: .All of the yellow offspring are heterozygous for color.
Explanation: do your chart
The offsprings could be yellow or green since the genotypes obtained after cross will be YY, Yy and yy Therefore, option (4) is correct.
What are Mendel' law?The following is an outline of Mendel's laws of inheritance:
The principle of dominance is the foundation of the laws of inheritance. The law specifies that hybrid offspring will only inherit the dominant phenotype. The alleles that do not show in an individual are referred to as recessive traits, whereas the alleles that do manifest are referred to as dominant traits.
The alleles for each gene separate from one another during the process of gamete creation, ensuring that each gamete carries just a single copy of each allele for the genes that it contains. This is known as the law of segregation.
The law of independent assortment states that genes for various characteristics might segregate in an unrelated fashion while gametes are being formed.
