What can the result be if DNA replication does not occur without errors?
A. No genetic diversity
B. It has not been researched enough yet to know
C. A perfect, mutation-free society
Answer:
C. A perfect, mutation-free society
Explanation:
Mutation is a genetic phenomenon involving the alteration or change in the genetic sequence of a gene. Mutation is commonly caused by mutagens (chemical substances that induce mutation), DNA replication mistakes or errors etc.
According to this question, if DNA replication occurs without error, this means that mutation will likely not occur, leading to a perfect, mutation-free society.

A 1500 kg car sits on top of a car carrier truck 2.5 meters above the ground how much potential energy does the car have
Answer:
36,787.5 Joules
Explanation:
Potential Energy = mass * acceleration due to gravity * height
U = mgh
We know the following:
mass = m = 1,500 kg
acceleration due to gravity = g = 9.81 m/[tex]s^{2}[/tex]
height = h = 2.5 m
When we substitute each value into the formula we get the following:
U = 1,500 kg * 9.81 m/[tex]s^{2}[/tex] * 2.5 m = 36787.5 kg[tex]\frac{m^{2}}{s^{2} }[/tex] = 36,787.5 Joules

Will people pick up a dollar bill that is dropped on the floor in the airport during a pandemic?
Answer:
No.
Explanation:
The factors of an experiment is considered as independent because it does not change or not dependent on other while on the other hand, the data is the dependent variable due to its dependency on the treatments. No, people will not pick up a dollar bill which is dropped on the floor in the airport during a pandemic because they can't put their life in danger for a dollar. They knew that life is more important than money.

3. The Amazonian rain forest is a captivating natural habitat rich in wildlife diversity. Around 3600 different spider species inhabit the area and one of these species of the Laluca lokita. This species is characterized by its great strength and territorial aggressiveness as well as its powerful venom. Within the species, the brown colored abdomen is dominant to the recessive black colored abdomen. Throughout the study of these arachnids, scientific research also found that hairy legs is dominant to hairless legs in this species. During the mating season, a brown, hairy male spider mates with a black, hairless female. In the F1 generation, all of the progeny are brown and hairy. When the progeny of this generation is able to reproduce, a male spider of the F1 generation mates with a black, hairless female. When the resulting progeny are observed for these two traits, 180 are brown and hairy, 185 are brown and hairless, 188 are black and hairy, and 182 are black and hairless. What are the genotypes of the two original parents

An individual has the genotype Aa Bb CC Dd ee FF. How many different types of gametes could it produce in terms of unique allelic combinations of these genes?
Answer:
64
Explanation:
The individual in this question with genotype: Aa Bb CC Dd ee FF has six (6) different traits encoded by six (6) genes. The diploid number of the organism in this question is 12, however, the number of possible allelic combinations in each gamete can be calculated by using 2^n where n = haploid number of chromosome or number of allele that can be in one gamete.
Using this simple formula, 6 possible alleles can be in the gamete of this organism with the above genotype, hence, the individual can produce 2^6 = 64 different types of gametes in terms of unique allelic combinations of these 6 genes.

A DNA sample is anyalyzed and you find that 22% is cytosine. How much thymine would be in the same cell?
Answer:
28% Thymine
Explanation:
DNA molecule is made up of four nucleotides namely: Adenine (A), Thymine (T), Cytosine (C), and Guanine (G). These nucleotides make up the DNA molecule unevenly, however, according to Chargaff in his rule, he stated that the amount of Adenine&Thymine, Guanine& Cytosine in a DNA must be equal, which must all equate to 100% i.e. (A = T) + (G = C) = 100%
Based on this Chargaff's rule, if a DNA sample is analyzed and found to contain 22% of cytosine. This means that the amount of Guanine in that DNA sample must also be 22%.
Therefore; 22% C + 22% G = 44%
100 - 44 = 56%. This means that Adenine and Thymine will share this 56% among each other i.e. 56/2 = 28% Adenine and 28% Thymine.

Which of the formed elements arise from myeloid stem cells?
a) B cells
b) natural killer cells
c) platelets
d) all of the above
Answer:
c
Explanation:
it creates platelets and a myeloblast, or monocytes
The formed elements that may arise from myeloid stem cells are platelets. Thus, the correct option is C.
How myeloid progenitor cells are formed?The myeloid progenitor cells are formed from the hematopoietic stem cells which are of multipotent nature. Such HSC cells induce the transcription factor GATA-2 and give rise to myeloid progenitor cells.
The process of hematopoiesis occurs in the bone marrow in which HSCs play a major role in synthesizing the blood cells.
The myeloid progenitor cell further produces dendritic cells through the transcription factor FLT3L, eosinophils through IL-5, mast cell, platelets through thrombopoietin, RBCs through erythropoietin, etc.
Therefore, among the given options, platelets are derived from myeloid stem cells. Thus, the correct option is C.
