A mutation in a gene that controls mitosis in cells may cause? a) cancer. b) cystic fibrosis. c) albinism. d) meiosis.


Answer 1
Answer: The answer is a) cancer.

Cells must control mitosis (cell division) in order to maintain normal cell function. If something happens to the control of mitosis, the healthy cells will divide uncontrollably. These new cells are cancer cells and they are also out of control. They will continue to divide uncontrollably, so the mass of the cancer cells will grow.
Regarding other choices:
- cystic fibrosis is an inherited disorder of lungs and digestive system,
- albinism is a congenital disorder characterised by the absence of pigment in the skin and hair,
- meiosis is cell division resulting in the reduction of a chromosome number in half.

What is the systematic study of natural


The systemic study of natural world is called natural science. It is concerned with the understanding of natural phenomena based on collected data, knowledge or sense of experience by means of observation and experimentation. Natural science is subdivided into two main branches: one is biological science or life science which aims to study life and living organisms their function, structure, evolution, growth, distribution and taxonomy second is physical science which is also broken down into different branches, including Earth science, astronomy, chemistry and physics. 


A structure located above the transverse plane is said to be: A. Lateral
B. inferior
C. superior


It wouldn't be B because inferior means below, and it wouldn't be A because lateral means away from the vertical mid-line of the body. This leaves you with C, superior, which means relatively above something in anatomical terms.

Easter Island is a small island in the southern Pacific Ocean. It lies approximately 3,500 kilometers east of Chile and is considered one of the most remote islands. It is also a volcanic island. In 2025, Easter Island had a population of 16,000. However, many of the island’s residents were killed during a series of volcanic eruptions that occurred in the year 2065. Of the original population, only 200 people survived. It is now 100 years later, and the population of Easter Island has reached 800. Of the current population, 328 people are homozygous recessive for Marfan syndrome, which is autosomal (mm genotype). Marfan syndrome is a genetic disorder that affects the connective tissue. Symptoms of Marfan syndrome include increased height, thinness, flexible joints, heart complications, and long arms, legs, fingers, and toes. q^2 -

The original population’s actual genotype frequencies were: MM – 0.42, Mm – 0.13, mm – 0.45.
1.) Is the current population in Hardy - Weinberg equilibrium? Yes or No
2.) Is the current population evolving? Yes or No
3.) If the current population is evolving, what type of effect is responsible for genetic drift?


A. Yes, the current population in Hardy - Weinberg equilibrium follows.

p = 0.36 (dominant allele)

q = 0.64 (recessive allele)

p² = 0.13

2pq = 0.46

q² = 0.41

What is hardy Weinberg equation?

The Hardy-Weinberg equation is a mathematical equation used to calculate the genetic variation of a population at equilibrium.

Here, we need to use the Hardy-Weinberg equations:

p + q = 1

p² + 2pq + q² = 1

p: the frequency of the dominant allele

q: the frequency of the recessive allele

p²: the frequency of homozygous dominant

2pq: the frequency of heterozygous

q²: the frequency of homozygous recessive

Here, we know that 328/800 people are homozygous recessive, which means that q² = 328/800 = 0.41.

Then, q = √0.41 = 0.64, and p = 1 - q = 1 - 0.64 = 0.36.

Now, we have p² = (0.36)² = 0.1296 ≈ 0.13 and 2pq = 2 * 0.36 * 0.64 = 0.4608 ≈ 0.46.

Final answer:

p = 0.36

q = 0.64

p² = 0.13

2pq = 0.46

q² = 0.41

B. To know if a population is in Hardy-Weinberg Equilibrium scientists have to observe at least two generations. If the allele frequencies are the same for both generations then the population is in Hardy-Weinberg Equilibrium. Yes, the current population in Hardy - Weinberg equilibrium.

Explanation:Define as it relates to adaptation


Tell whether the statement is TRUE or FALSE: Convection currents produce the heat in the Earth’s interior.


It is true that the convection currents produce the heat in the Earth's interior. The correct answer is True. 

The answer is FALSE. Convection currents do not produce the heat in the earth’s interior. They are rather responsible for distribution of this heat in the mantle. The radioactivity of the earth's core is the main source of heat. As the materials such as uranium decay, they release heat that keeps the interior hot.

An ecosystem in which all of the associated species are stable and uniform is called a A. climax community.
B. primary community.
C. secondary community.
D. pioneer community.


An ecosystem in which all of the associated species are stable and uniform is called a climax community.

The climax community is the process in which simple communities of species are replaced by more complex populations and the  ecosystem stabilizes.

  • It refers to the moment when the  ecosystem will have a large number of species and ecological niches and will be in balance.

  • The climax of a community occurs when it reaches a state of stable development in which there is little biomass growth.

  • A climax community can tolerate the environmental conditions it causes, and the species that make up the community differ from biome to biome.

  • An ecosystem can be climaxed for a very long time, like tropical forests.

Therefore, we can conclude that an ecosystem in which all of the associated species are stable and uniform is called a climax community.

Using the principles of natural selection, __________ studies how behavior and the mind have evolved.



Evolutionary psychology


Evolutionary psychology is the theoretical branch of psychology that describes that how the human behavior have evolved by the effect of evolution through a lens

  • Only body is not effected by evolution but the brain is also sculpted; the behavior it produce and psychological procedure.
  • There were many psychological mechanisms that were involved in survival of species known as psychological adaptation.
  • The psychological adaptations and their byproducts that are activated in modern environment are different from their ancestral environment in some features.
