An oceanographer discovered a deep underwater opening as shown in the illustration. the scientist classifies this as a mid-ocean ridge. is the scientist correct or incorrect and why or why not?
The answer is He is incorrect. Mid-ocean ridges are sites of divergent oceanic plates.

My doctor also explained that birth control pills "trick the body into thinking it is pregnant." she explained that women do not normally ovulate when they are pregnant. can you explain to me why a pregnant woman does not ovulate? how is this related to how the birth control pill works?
Suppose a gene has two alleles one of which is dominant over the other
The recessive alleles show their presence when present in a pair. The recessive alleles are the alleles which when present in two copies of the allele whose effect is hidden unless the other allele is absent. Thus, the correct option is B.
What are recessive alleles?Recessive alleles are the forms of a gene which when present with a dominant allele does not show their effect but when present in homozygous condition shows their effect.
Suppose a gene controlling height has two allele (T & t):
Then the possible genotypes will be
TT for tall homozygous dominant (with a pair of the same allele)
Tt for Tall heterozygous dominant (with two different alleles of the same gene)
tt for dwarf homozygous (with a pair of same alleles)
Here, allele "T" is dominant over allele "t". Allele "t" will be only expressed when allele "T" is absent.
Therefore, the correct option is B.

a. Two copies of the allele that determines phenotype whenever the allele is present
b. Two copies of the allele whose effect is hidden unless the other allele is absent
c. One copy of the allele that determines phenotype when present and one copy of the other allele
d. One copy of each of the two alleles that both contribute equally to determining the phenotype

The ability of an individual to distinguish between similar stimuli is called _____.
The ability of an individual to distinguish between similar stimuli is called Sensory discrimination.
What is Stimuli?A stimulus is defined as a detectable change in the physical or chemical composition of an organism's internal or external environment. The ability of an organism or organ to detect external stimuli in order to make an appropriate response is called sensitivity.
It is defined because it can trigger a physiological or behavioral change. Stimuli can be external or internal such as external stimuli the body is responding to a drug while the internal stimuli are vital signs that change due to changes in the body.
When the individual has the ability to distinguish between similar stimuli is known as Sensory discrimination.
Thus, the ability of an individual to distinguish between similar stimuli is called Sensory discrimination.

Pyruvate and acetyl groups are common chemical intermediates called __________.
Answer:
Pyruvate and acetyl groups are common chemical intermediates called metabolites.
Explanation:
Metabolites are the organic intermediates or end products that arise after processing of a given substance in a biological system or living being such as bacteria, other single-celled organisms, plants and animals. Metabolites include, among others, amino acids, adenosine triphosphate, glucose, adrenaline, alkaloids, and glycosides.
In the case of medicines or pharmaceuticals, metabolites generally refer to the end products that remain after metabolism, or biotransformation. Metabolism of drugs and many other foreign substances takes place in the liver.
Suppose that you have just graduated from college and have started working at a biotechnology firm. your first job assignment is to clone the pig gene for the hormone prolactin. assume that the pig gene for prolactin has not yet been isolated, sequenced, or mapped; however, the mouse gene for prolactin has been cloned, and the amino acid sequence of mouse prolactin is known. briefly explain two different strategies that you might use to find and clone the pig gene for prolactin.
The lava released by a volcanic eruption separates two populations of a species of monkey. What does this represent?
Answer:
Geographical Isolation
Explanation:
Lava serves as geographical barrier to separate the two populations of monkey. These two isolated populations accumulate variations and gradually become reproductively isolated. Reproductive isolation brought about by geographical isolation leads to formation allopatric species which are now present in different geographical regions.
Answer:
Geographical Isolation
Explanation:
Geographic isolation consists of separating a population by a geographical barrier, thus forming subpopulations. The geographical barrier can be a river, a mountain or a volcanic eruption, as shown in the question above.
As a result of geographic isolation, subpopulations begin to suffer different pressures and consequently the genes selected in one subpopulation will be different from the other subpopulation. Due to the geographical barrier, the two subpopulations will be prevented from crossing and the differences between them will become increasingly pronounced. Thus arose the subspecies.
Temperature is an important physical feature of an ecosystem. which option below shows a correct, direct relationship between temperature and organisms in an environment? bsc2005
6) DNA and RNA differ in all BUT one of the following ways. A) DNA is double-stranded, while RNA is single stranded. B) RNA uses the sugar ribose in its backbone, while DNA uses deoxyribose. C) DNA contains the base uracil, while RNA contains the base thymine instead. D) DNA is found in chromosomes in the nucleus, while RNA can move around the cell.
How is a cow eating grass a part of both carbon and oxygen cycle
Answer:
The cow breaths out the carbon on the plant and the plant then puts out oxygen into the cow.
Explanation:
The Carbon Cycle begins when plants and other autotrophic organisms absorb carbon dioxide from the atmosphere to use it for photosynthesis. In this process, the carbon is returned to the medium at the same speed at which it is synthesized by the producers, since the carbon return occurs continuously through breathing during the life of beings. In this case, we can say that a cow participates in the carbon cycle, when it eats a plant and releases the carbon through expiration.
Several processes are related to the oxygen cycle, with photosynthesis standing out. In this process, photosynthetic organisms use carbon dioxide, in the presence of sunlight, to form organic molecules and release oxygen, which is used by living beings in cellular respiration. In this case, we can say that cows participate in this process, when they breathe in the oxygen released by the plants.

Wheat, corn, soybeans, and cabbage are the main four plants responsible for providing food to people in the world. D. The green revolution was instrumental in the increase of the world's food supply.
