1. The given blank can be filled with vestibular nerve.
The vestibular nerve in humans conducts sensory information conducted by the vestibular hair cells situated in the utricle and the saccule, that is, the two otolith organs, and the three semicircular canals through the vestibular ganglion. It relays information to the brain about balance.
2. The correct answer is option b, that is, the vestibular sense may be capable of sensory adaptation.
The awareness of the movement and the balance of the body are controlled by the vestibular system. The vestibular senses, that is, the feelings of gravitation and movement and rotation of the body originate in the inner ear. The sense organs are the cells of the hair, which transmit signals over the auditory nerve.
Answer:
The simple equation for lactic acid fermentation is glucose ---glycolysis---> 2 pyruvate ---fermentation--> 2 lactic acid. And the molecule for lactic acid looks like this: Lactic acid, also called lactate. This is the end product of lactic acid fermentation.
Answer:
2 chromosomes
Explanation:
The cell of an eukaryotic organism like roundworm contains the Nucleus, which harbors the genetic material embedded in the chromosome. The number of chromosomes of that organism is contained in each cell.
Somatic cells, also called body cells, are all other cells asides sperm and eggs, that form the tissues and organs of an organism. Somatic cells are usually diploid i.e two sets of chromosomes from each parent. In this question, the roundworm has 4 chromosomes in its somatic cell.
The reproductive cells or sex cells (sperm and eggs) of an organism always result from meiotic division of specialized cells.
Since meiosis is a kind of division that results in cells with their chromosome number reduced by half (haploid), it therefore means that the ovum and sperm cell will be expected to contain 2 chromosomes each.
This way, when fertilization occurs (sperm and egg fusion), the resulting zygote, which will eventually develop into an adult organism, will have 4 chromosomes.
It contains connective tissue, nerve endings, and hair follicles. Subcutaneous tissue is the third layer of the skin. Located beneath the dermis and epidermis, it is mostly fat. These skin cells produce the protein keratin, the basic structural component of hair and nails.
So I would say True.
Hope This Helps! Have A Nice Day!!
