A simple diagram of a DNA molecule is shown below. Which of the following is represented by X?
(photo above)
Answers
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.

-herd immunities
-phagocytes
-lymphocytes
-endospores
-antigens
Answers
Answer:
Antigens
Explanation:
Herd immunity is not something found on the surface of a cell. It is something a whole herd or population develops in order to fight some disease.
Phagocytes are not found on the surface of any cell since they are cells themselves. They protect the body by ingesting particles, bacteria, and dead cells.
Lymphocytes are white blood cells
Endospores are made by bacteria and not located on the cell surfaces.

How do you think the body processes monosaccharides differently than polysaccharides? Would they take the same amount of time to digest and harvest energy?
Answers
Answer:
Polysaccharides from cell walls make up the fiber humans eat, while monosaccharides provide the sweetness in foods. As humans eat, chewing breaks down polysaccharides into smaller particles that eventually, through digestion, yield up the simple monosaccharides that can pass into the bloodstream.

what came first the chicken or the egg
Answers
Eggs were found to evolve for over a billion years ago whereas chicken have been found to evolve around for just over 10,000 years. Thus, it can be concluded that eggs came first followed by the chicken.
What is Evolution?Evolution can be defined as any net directional change or cumulative change in the characteristics or traits of an organism or populations over many generations in order to survive better in the surrounding environment.
Eggs come from chickens and chickens come from eggs. It is the ancient riddle. However, eggs are just the female sex cells which were supposed to have evolved more than a billion years ago, whereas chickens have been found to evolve around for just 10,000 years ago. Therefore, it can be said that the eggs have came first followed by chickens.
The amniotic eggs shows up to roughly 340 million or so years ago, and the first chickens evolving at around 58 thousand years ago at the earliest. Thus, eggs were around way before chickens even existed.

Honey Bees have a much different social and reproductive structure as compared to humans.
With honey bees, the queen bee contains more chromosomes with 32 than her drones do at
16 chromosomes. If the queen bee is identified as a Diploid, how would the drones be
classified?
O Haploid
O Diploid
O Monosomy
O Trisomy
Answers
Answer:
Unlike the queen bee, which has 32 chromosomes, drones have half the chromosomal charge (n= 16), so they are considered haploid.
Explanation:
The system of determination of the sex in the bees —like in other insects— is called haplodiploidy, and consists of which the females of the species possess complete charge of chromosomes, whereas the males only possess half. This is what happens with the queen bee with 32 chromosomes, while drones only have 16 chromosomes, so they are considered haploid.
Additionally, as a characteristic of haplodiploidy, males only proceed from female gametes, so they can only contribute gametes to produce females of the species.
The other options are not correct because:
Drones, with half of the chromosomal charge, cannot be diploid. Monosomy and trisomy are defects in the distribution of chromosomes during meiosis, which imply one chromosome less or one chromosome more in the normal chromosome charge respectively.
