Answer:
The options to this question are;
A. genotype
B. adaptation
C. selective pressure
D. stabilizing pressure
The answer is B) Adaptation
Explanation:
Adaptation is the process whereby an organism becomes well suited to survive in its natural environment, which is aided by the possession of certain traits called adaptive features. For example, the fins of a fish makes it fit to survive in an aquatic environment, likewise the opposable thumbs of humans make us well suited to survive in our environment.
As stated in the question, the opposable thumb i.e. movement of the thumb independently of the other four fingers, is a characteristics of primates. This unique feature (opposable thumb) allows us to grab things, get a good grasp of tools, use tools effectively, write things, etc. All these ability due to the possession of opposable thumb increases our chances of survival. Hence, the possession of opposable thumb is regarded as an ADAPTATION
what is meant by photosynthesis
Answer:
Photosynthesis is a physio-chemical process by which green plants use light energy to drive the synthesis of organic compounds. It is an enzyme regulated anabolic process.
Explanation:
Answer:
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. ... This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.

Which characteristic does a virus have in common with a eukaryotic cell?
Viruses are not cells; they are a strand of genetic material within a protective protein coat called a capsid. They infect a wide variety of organisms, including both eukaryotes and prokaryotes. Once inside the cell, they use the cell's ATP, ribosomes, enzymes, and other cellular parts to replicate.
The characteristics that a virus cell possess with eukaryotic cell is that they both possess a genetic material.
What is an eukaryotic cell?An eukaryotic cell is a cell that has a genetic material bound by membrane-bound nucleus.
A virus cell, on the other hand, is a cell that is incapable of replicating itself without a living host.
However, one similarity between the eukaryotic cell and viral cell is that they both possess a genetic material that stores their genetic information.

The conversion of glucose to glucose 6-phosphate is an enzyme-catalyzed reaction. During this reaction, the enzyme hexokinase folds around the substrates to bring reactive side chains from the active site into alignment with the substrates. This change in hexokinase is an example of
Answer:
Induced fit
Explanation:
Induced fit (IF) is a model used to understand enzyme-substrate interactions, which can be considered as a development of the classical lock-and-key model. This model (IF) was proposed by Daniel Koshland (1958) in order to understand protein conformational changes during the binding process. The model states that the active site of the enzyme, i.e., the region where the substrate binds and catalyzes the reaction, is reshaped when it binds with its substrate in order to improve the fit. The IF model assumes that the active site of the enzyme is flexible and is capable of changing its shape until the substrate is completely bound.

Endometriosis occurs when endometrial tissue, which normally grows inside the uterus, grows outside the uterus. Based on the model, what effects would you expect these growths to have on the female reproductive system and on fertility?
Answer:
Endometrosis could negatively affect the probability of gestating an embryo if they are growing inward. The affection of the fallopian tubes and the uterus could alter the implantation or even generate complications for the embryo during pregnancy.
In addition, endometriosis generates painful conditions in the abdominal area to the point that it is considered as menstrual cramps during menstruation, women who suffer from this disease suffer a lot during the menstrual cycle.
Regarding the reproductive system, those female reproductive systems that suffer from this disease are considered potentially malignant, since many malignant neoplasms are incited to appear in these foci of excessive proliferation of the endometrium.
Explanation:
Endometriosis can affect the walls of the fallopian tube and the uterus, since it occurs in the endometrium, that is why it bears that name.
The macroscopic appearance of this lesion at the histological level is a tumor nodule, since they are proliferative foci.
Answer:
abnormal tissue growing on the ovaries might affect ovulation, making it harder or impossible for women to get pregnant. The extra tissue may cause pain, since the tissue is growing in places it is not meant to be growing

What happens when volcanoes release greenhouse gases into the atmosphere?
Answer:
a. the climate gets warmer...
Explanation:
When volcanoes release greenhouse gases into the atmosphere, global warming is due to the greenhouse effect.
What do you mean by the Greenhouse effect?The Greenhouse effect may be defined as the phenomenon of keeping the earth warm due to the presence of certain gases in the atmosphere.
Greenhouse gases like carbon dioxide, Methane, and Nitrous oxide allow the solar radiations to enter but prevent the escape of heat radiations of longer wavelength.
Due to this, the gradual and continuous increase in the average temperature of the earth's surface occurs, a phenomenon known as global warming.
Therefore, when volcanoes release greenhouse gases into the atmosphere, global warming is due to the greenhouse effect.

Without the discovery of magnetic reversals recorded on the ocean floor, scientists
A. could not confirm the usefulness of sonar
B. could destroy the hypothasis of continental drift
C. could not provide a mechanism for moving continents
D. could explain how the seafloor was being destroyed
Answer:
C. could not provide a mechanism for moving continents
Explanation:
Magnetic reversals have the habit of causing geological displacements, since they are directly linked to the movements and distribution of tectonic plates on the planet, which are responsible for the movements of the continents. In this case,
if the discovery of magnetic reversals recorded on the ocean floor were not carried out, it would be impossible to establish its relationship with the movement of the tectonic plates, making it impossible to provide a mechanism for moving continents.
Evolution is defined as a change in allele frequencies in a population over time.How is the relationship between malaria and sickle cell n example of human evolution?
Answer:
Dramatic evolution within human genome may have been caused by malaria parasite. A genetic mutation that protects people from a common form of malaria spread like wildfire in sub-Saharan Africa about 42,000 years ago, according to a new study.
People develop sickle-cell disease, a condition in which the red blood cells are abnormally shaped, if they inherit two faulty copies of the gene for the oxygen-carrying protein haemoglobin. The faulty gene persists because even carrying one copy of it confers some resistance to malaria.05-May-2011
Explanation:
An evolutionary force, called balancing selection, appears to be responsible for maintaining defects in our DNA associated with diseases, such as sickle cell anemia, because the mutation's damaging effects might be offset — in a biological way of thinking — by its potential benefits.
In brief state what happens when a) dry apricots are left transferred to sugar solution? b) a Red Blood Cell is kept in concentrated saline solution? c) the Plasma-membrane of a cell breaks down? d) rheo leaves are boiled in water first and then a drop of sugar syrup is put on it? e) golgi apparatus is removed from the cell?
Answer:
Explanation:
(a) Dry apricots when placed in pure water swell due to osmosis and when in sugar water, they shrink again.
(b) When a Red Blood Cell is placed in concentrated saline solution exosmosis occurs and the RBCs shrink due to excess loss of water.
(c) Breaking of the plasma membrane leads to the scattering of the ceil organelles as it forms the basic supporting unit of the cell.
(d) When Rheo leaves are boiled in water first and then a drop of sugar syrup is put on it, osmosis does not occurs, due to the death of the cells of the leaf. This shows that selective permeability is property of living plasma membrane.
(e) Golgi complex helps in the package, storage and transfer of proteins synthesized by ribosomes. Thus, when ribosomes are removed the cell will not function properly

What are the two components of the scientific name of a species in the Linnaean system? Select all that apply. Genus, Specific epithet, Phylum, Family.
Answer:
Genus, Specific epithet
Explanation:
The scientific name was created to establish a standardized language that would allow scientists and scholars around the world to be able to present living beings independently of their native language.
For this purpose, it was decided that the scientific name would be a binomial composition, that is, it would use two names. The first name refers to the genus to which the species belongs, the second name refers to the specific epithet that is the specific descriptor of that species. In addition, the scientific name should be written in italics and have the first initial letter written in uppercase. Ex: Homo sapiens.

The process whereby the earth’s life changes over time through changes in genes of populations of organisms in succeeding generations is called____.a. emigration.b. mutation.c. natural selection.d. evolution.e. genetic drift.
Answer:
The correct answer is option : d. evolution.
Explanation:
Change in the heritable traits or characteristics of population of a organism over time by the adaption or changes in genes of such population over successive generation is known as the evolution.
These changes that cause the evolution of the biological population is caused by the process of adaption through natural selection that is the ability of the passing beneficial genes from parent to offspring.
Thus, the correct answer is option D. evolution.
