The diagram above depicts a karyotype of an individual human. Which of the following statements concerning the karyotype in the diagram is true? Select all that apply.
o The diagram indicates an individual with an extra sex chromosome
o The diagram illustrates a genetic condition found in females.
o The diagram illustrates the results of nondisjunction during gamete formation.
o The diagram indicates a mechanism for increasing genetic diversity in subsequent generations.
Answers
The statements about the karyotype in the diagram are correct, that the diagram depicts the effects of nondisjunction during gamete formation. Thus, option C is correct. Thus, option C is correct.
What is the Karyotype?Karyotype refers to the number and arrangement of chromosomes in the nucleus of a eukaryotic cell. It is depicted as a diagram, as shown above. There is no Down syndrome because the karyotype shows a normal pair of chromosomes 21.
There is an extra X-chromosome in this karyotype, indicating non-disjunction during either oogenesis or spermatogenesis (gamete formation) in the parents, resulting in the 23rd trisomy.
Therefore, option C is correct.

The lighter moth population will have a better chance of survival due to camouflage. Light moths will increase and dark moths will decrease due to industrial melanism. Therefore, option B is correct.
What is industrial melanism?Industrial melanism is a phenomenon in which the frequency of dark-colored or melanistic individuals in a population of organisms increases as a result of environmental pollution.
This phenomenon was first observed in the 19th century in industrialized regions of England, where the population of peppered moths shifted from mostly light-colored to mostly dark-colored in response to pollution from industrial activities.
Thus, the lighter moth population will have a better chance of survival due to camouflage. Light moths will increase and dark moths will decrease. Therefore, option B is correct.

Biotic factors are the living parts of an ecosystem. Because of the way ecosystems work – as complex systems of competition and cooperation, where the action of every life form can effect all the others – any living thing within an ecosystem can be considered a biotic factor. Biotic factors such as soil bacteria, plant life, top predators, and polluters can all profoundly shape which organisms can live in an ecosystems and what survival strategies they use.

Likewise, natural killer cells target human cells for destruction. Explain why it is advantageous for the immune system to have cells that can kill human cells as well as pathogens.

Answer:
Because Neutrophils has many other functions like
Neutrophils are the most abundant granulocytes that makeup about 40% of white blood cells and 60% of the immune cells in the blood.Neutrophils are the first responders to infection, and they phagocytose bacteria into phagosomes before hydrolyzing and destroying them.These cells also secrete a range of proteins that have antimicrobial effects as well as tissue remodeling potential.Neutrophils have a short lifespan and thus destroy themselves during the degradation of foreign invaders. New neutrophils are then produced continuously in the bone marrow.The neutrophils of another subpopulation, cager neutrophils, perform a transport function of delivering foreign particles to the target site for the action of killer neutrophils.Like wise Natural killer (NK) cells are effector lymphocytes of the innate immune system that control several types of tumors and microbial infections by limiting their spread and subsequent tissue damage.

A plant species live in an area with limited sun.Which physiology adaptation would be most useful to the plant?
Answers
Answer:
The correct answer is - large leaves.
Explanation:
Chlorophyll is the green pigment present in the chloroplast found in the plant cells that is used to make food or glucose from sunlight. These pigments are present in a high amount on the leaves of the plant.
If a plant lives in an area with limited sun then there will be a limited amount of sunlight for that plants adapt accordingly and big leaves are one of them. Big leaves have more chlorophyll and the more the pigment higher the amount of energy is trapped by the plant for food production.

Rates of extinction tend to be higher on islands than on the mainland.
O True
O False
Answers
Answer:
True.
Explanation:
In biogeography, extinction is the ending of the existence of some species or other taxonomic group. It is a normal natural phenomenon. Species are becoming extinct because the factors that keep the population small, such as diseases or predators, are increasing, because their living environment is changing drastically due to climate change, for example, or because competition is increasing.
Thus, if these species are enclosed in small and dead-end territories, such as an island, their extinction will be easier, since they will not have the possibility of migrating (except for birds) or expanding territorially.

The two major sources of energy for the rock cycle are the sun, which provides energy for surface processes such as weathering, erosion, and transport, and the Earth's internal heat provides energy for processes like subduction, melting, and metamorphism. And Magma, when it is allowed to cool, it crystallizes, much the same way that ice crystals develop when water is cooled. We see this process occurring in places like Iceland, where magma erupts out of a volcano and cools on the surface of the Earth, forming a rock called basalt on the flanks of the volcano
----------------------------------------
how each source of energy causes the rock to change forms:
Over many thousands of years, energy from the Sun moves the wind and water at the Earth’s surface with enough force to break rocks apart into sand and other types of sediment. When sediment is buried and cemented together, it becomes a sedimentary rock such as sandstone or shale.
Magma is a hot liquid made of melted minerals. The minerals can form crystals when they cool. Igneous rock can form underground, where the magma cools slowly. Or, igneous rock can form above ground, where the magma cools quickly.
if a strand of DNA has the sequence ATGCGATCCGC, then the sequence of the MRNA molecule transcribed from it is
Answers
Answer:
DNA: ATGCGATCCGC
mRNA: UACGCUAGGCG
Explanation:
The deoxyribonucleic acid (DNA) is a double-stranded helix, where each strand is composed of four nitrogenous bases: Adenine (A), Thymine (T), Guanine (G) and Cytosine (C). The two strands are held together by hydrogen bonds and they interact in the following way: Adenine (A) always pairs with Thymine (T) through two hydrogen bonds, while Guanine (G) always pairs with Cytosine (C) through three hydrogen bonds. During transcription, a DNA strand of the double helix DNA molecule is used as template to synthesize a complementary RNA molecule, usually, a messenger RNA (mRNA) which is then used to create a protein by the process of translation. Moreover, also during transcription, Thymine (T) bases are replaced by Uracil (U) bases in the RNA molecule.
