If 30% of the bases in a particular DNA molecule are guanine (G), what percentage of the bases would be thymine (T)? Explain your reasoning.
Answers
Answer:
20%
Explanation:
There are four bases in DNA: guanine (G), cytosine (C), adenine (A), and thymine (T). They all have to add up to 100%. In DNA, guanine pairs with cytosine and adenine pairs with thymine.
If guanine is 30%, cytosine is also 30%.
30% + 30% = 60%
Now subtract from 100%.
100% - 60% = 40%
Thymine and Adenine make up 40% of the DNA. Now divide by 2 since there are two nitrogenous bases.
40% ÷ 2 = 20%
Guanine is 30%, Cytosine is 30%, Adenine is 20%, and Thymine is 20% for a total of 100% of the DNA.

Which of the following mutations is NOT a point mutation? A. Silent mutation B. Nonsense mutation C. Missense mutation D. Insertion mutation
Answers
the answer is Insertion mutation :)
(search up "types of mutations")
Point mutation is the alteration of the single nucleotide base in the sequence. Insertion mutation is not a type of point mutation. Thus, option D is correct.
What is point mutation?A point mutation is a modification and change in the base of the genetic sequence. In this type of mutation, only a single nucleotide base is altered. Point mutations are categorized as transition mutations and transversion mutations.
Silent, Nonsense, and missense are the transversion type of point mutation. In this mutation, the purines get altered by pyrimidines and vice versa. On the other hand, insertion mutation is the frameshift mutation.
Therefore, insertion is not a type of point mutation.

Answers
Answer:
1. merkel cells
2. tactile corpuscle
3. lamellated (lamellar) corpuscle
4. nociceptors
Explanation:
Merkel cells are epithelial cells found around hair follicles which are capable of sensing gentle touch sensations such as, for example, tactile discrimination and environmental exploration. Tactile corpuscles are a class of nerve ending required for mediating sensitivity to light touch sensations. The lamellar corpuscles are another class of nerve ending capable of sensing deep touch sensations and vibrations. Finally, nociceptors are somatic sensory receptors capable of sensing noxious (damaging) stimuli.
1. Light-touch receptor located at the epidermal-dermal border: Tactile corpuscles (D)
Light-touch sensors called tactile corpuscles, sometimes referred to as Meissner's corpuscles, are situated near the epidermal-dermal boundary. They are located in the papillary layer of the dermis's dermal papillae, which are tiny, finger-like projections.
Particularly dense populations of tactile corpuscles can be seen in skin regions like the lips, palms, and fingertips that are sensitive to gentle touch.

Which of the following statements are true? Multiple Choice Muscles work in antagonistic pairs because if one muscle pushes during contraction, the opposing muscle across the joint must pull. Muscles work in antagonistic pairs because muscles lengthen during contraction. Muscles work in antagonistic pairs because tendons lengthen during contraction. Muscles work in antagonistic pairs because if one muscle shortens during contraction, the opposing muscle across the joint must relax.
Answers
Answer
if one muscle shorten during contraction the opposing muscle across the joint must relax
The true statement among the statements above is that Muscles work in antagonistic pairs because if one muscle shortens during contraction, the opposing muscle across the joint must relax.
For better understanding, we have to know why muscle works in antagonistic pair and the reason for this pairing.
As the name implies, Antagonistic pairs is when muscles are set down or grouped in pairs. that is when a muscle tightens or shortens (contrast) and pulls, the other muscle will then be in a relaxed state so as to allow movement.
There is a great need or importance for antagonistic pairs in muscles. That is Muscles do perform its role in an antagonistic pairs because they can only reduce (shorten)making or taking the movement in one direction. There is also the need for another muscle that shortens in order to lead/make movement go in the opposite direction.
Example of this antagonistic muscle pairs is commonly found in insects where their exoskeleton in the hind leg of the insect gives room for the muscles to work in antagonistic pairs, also the tibia flexes and others.
therefore, we can conclusively say that the statement that Muscles work in antagonistic pairs because if one muscle shortens during contraction, the opposing muscle across the joint must relax is true.

Explanation:
A diploid human cell normally has 23 pairs of homologous chromosomes, but as a woman ages, the chances of nondisjunction increase. Imagine that a gamete is produced that received two copies of chromosome 21 due to nondisjunction during meiosis II. If the gamete is fertilized with a normal sperm, the embryo's cells will contain _______ chromosomes.
Answers
47 chromosomes instead of 46 because there are 3 chromosomes in pair 21. This is called Down syndrome, described most recently by Lejune in 1958
If the gamete is fertilized with a normal sperm, the embryo's cells will contain 47 chromosomes. The correct option is B.
What is nondisjunction?Nondisjunction refers to the phenomenon of unequal separation in meiosis.
If a haploid gamete has a missing chromosome due to nondisjunction, the diploid zygote it forms with another gamete will have only one copy of that chromosome from the other parent, a condition known as monosomy.
Nondisjunction occurs when the separation fails, causing both sister chromatids or homologous chromosomes to be drawn to one pole of the cell.
Mitotic nondisjunction can occur when topoisomerase II, condensin, or separase are inactivated.
Because pair 21 contains three chromosomes, there are 47 chromosomes rather than 46.
Thus, the correct option is B.

Explanation:
Under normal conditions in the body, blood and body tissues have a specific potent enzyme called proteases. Protease help in the breakdown of protein in the body and play important roles in defending or fight against incoming infections and inflammatory processes in the body .There is need for thslese proteases to be regulated or control because overactivity can lead to protein destruction which will lead damage of different body organs. In order to control this, blood and other tissues in the body posses enzymes with protease inhibitory activity, these enzymes help to prevent its from undergoing excessive action and potentially harmful effects.

C. to transport substances in and out of cells.
D. to store energy.
E. to form semipermeable membranes and to transport substances in and out of cells.
Answers
Answer:
D. to store energy
Explanation:
Triglycerides are a type of fat (lipid) found in your blood. When you eat, your body converts any calories it doesn't need to use right away into triglycerides. The triglycerides are stored in your fat cells. Later, hormones release triglycerides for energy between meals.
The main function of triglycerides is to store unused calories/energy to use later, so I believe it is D.
