Fovea is a tiny pit located in the macula of the retina in the eye provides the accurate vision.

Explanation:

The Fovea is mainly used for sharp central vision, that is very essential for human activities like reading and driving.

In the middle of the retina is a small dimple called the fovea or fovea centralis. A thin layer of light receptor cell covers the inner surface of the choroid.

It produces high visual clarity in the eye that produces sharpest vision and greatest color discrimination. The sharpness is because of high concentration of cone cells in the fovea.

Fovea, the blind spot is where the optic nerve connects to the retina in the back of each eye is known as optic disk.

How do the cells in meiosis differ from the cells in mitosis?

AfilCa [17]

Answer:

C. Cells in meiosis have unique genetic information

Explanation:

Meiosis is the cell division that forms four daughter cells from one parent cell. It includes two successive divisions called as meiosis I and meiosis II. Crossing over during prophase I of meiosis I imparts new gene combinations to the daughter cells of meiosis. Hence, daughter cells formed by the end of meiosis have some new gene combinations, that is, unique genetic information.

Which is a characteristic of something in the domain archaea

timurjin [86]

Answer:

Whereas both bacteria and archaea lack a nuclear envelope and membrane-bound organelles, archaea and eukaryotes have similarities beyond those seen between bacteria and eukaryotic cells. Bacteria have the macromolecule peptidoglycan in their cell walls; archaea and eukarya lack this polymer.

Faunal Succession—The principle of faunal succession, also known as the law of faunal succession, is based on the observation that sedimentary rock strata contain fossilized flora and fauna, and that these fossils succeed each other vertically in a specific, reliable order that can be identified over wide horizontal distances.

Original Horizontality—The Principle of Original Horizontality states that layers of sediment are originally deposited horizontally under the action of gravity. It is a relative dating technique. The principle is important to the analysis of folded and tilted strata.

lateral continuity—The principle of lateral continuity states that layers of sediment initially extend laterally in all directions; in other words, they are laterally continuous. As a result, rocks that are otherwise similar, but are now separated by a valley or other erosional feature, can be assumed to be originally continuous.

Superposition—Superposition is the ability of a quantum system to be in multiple states at the same time until it is measured.

Both intrasexual and intersexual selection usually cause changes in phenotypes for males and little changes in female phenotypes

Selection is usually strongest in the male of the species. D) because sperm are small and plentiful, while eggs are large and energy-rich.

Phenotype refers back to the observable traits of an organism as a multifactorial effect of genetic trends and environmental influences. The organism phenotype includes its morphological, biochemical, physiological, and behavioral residences.

A person's genotype is their specific collection of DNA. extra especially, this term is used to refer to the two alleles a person has inherited for a selected gene. Phenotype is the detectable expression of this genotype – a patient's clinical presentation.

The sum of an organism's observable traits is its phenotype. A key difference between phenotype and genotype is that, even as genotype is inherited from an organism's parents, the phenotype isn't.

Both intrasexual and intersexual selection usually cause changes in phenotypes for males and little changes in female phenotypes. Why is sexual selection usually strongest in the male of the species?

a. Males are naturally more aggressive

b. Males have a smaller genetic component than females due to fewer X chromosomes

c. Males do not pass on their mitochondria and therefore have more invested in each individual mating event

d. Because sperm are small and plentiful, while eggs are large and energy-rich.

Which is the most likely outcome for a species of fish that lacks the genetic variation necessary to adapt to a changing ocean e

ZanzabumX [31]

Genetic variation is the variation in the DNA sequence in the genome of an organisms. Organisms of a species have similar characteristics but they are not identical due to genetic variation. Genetic variation is important in the survival and the adaptability of a given species of organism. Therefore, in this case lack of genetic variation necessary to adapt to change in the environment will lead to extinction of the fish species that lacks the variation.
