Functional magnetic resonance imaging (fMRI) is the neuromarketing technique that looks for active areas in the brain by measuring the amount of oxygenated blood flowing through the body.
Functional magnetic resonance imaging (fMRI) is a noninvasive technique for measuring the activities of the brain. This technique is used to observe the brain’s functional anatomy as it reveals the parts of the brain that are involved in a certain mental process. fMRI functions by using magnetic resonance imaging to measure the small changes in blood oxygenation and flow that take place as a result of activities of nerve cells in the active areas of the brain.
Answer:
The cytoplasm of the egg cell is same as like that of the ordinary cell's cytoplasm.
It has yolk in its center which contains nucleus, nucleolus and germinal spot.
The mammalian ova contains a small amount of nutritive yolk which provides the nourishment to the embryo for a time being.
The cytoplasm of the unfertilized egg contains some unevenly distributed proteins, specifically the cytoplasmic determinants.
These determinants are the substances that plays a major role in the oocyte formation and maturation. Sometimes they are clumped together and then divided heterogenitically.
Answer:
Explanation:
A gene pool typically has two or more alleles for a given trait. Homozygous lethal traits can be carried by heterozygous individuals and thus remain in a gene pool. Relative Frequency is the number of times an allele occurs in a gene pool compared with the number of times other alleles occur.
The answer is D. Phospholipids are diglycerides (two fatty acid chains covalently bonded to a glycerol molecule)
that are covalently bonded to a phosphate group by an ester linkage. Fatty
acids are long chains that are mostly made up of hydrogen and carbon, while
phosphate groups consist of a phosphorus molecule with four oxygen molecules
attached. Glycerol is a 3 carbon chain containing hydroxyl groups in each of the carbon.
Answer: c. iris – controls the pupil
Explanation:
The iris, a structure which is primarily made up of smooth muscles. These smooth muscles surrounds the pupil. The light enters the eye through pupil which is a black hole present in the middle of the eye. It allows the light to strike the retina. It controls the size of the pupil this way it helps in regulating the amount of light entering the eye. The pupil becomes wider in the darkness and becomes narrower when the light intensity is more. These actions are controlled by iris.
