Is a general increase in the bulk of a body part or organ that is due to an increase in the size of cells in the tissues?

Answers

Answer 1

Hypertrophy is a general increase in the bulk of a body part or organ that is due to an increase in the size of cells.

When parenchymal cells are injured or destroyed, hypertrophy may arise as a compensatory reaction. For example, after a myocardial infarction, cardiac myocytes cannot undergo hyperplasia to replace damaged muscle fibers, but remaining myocytes increase (hypertrophy) to compensate for part of the function of the lost myofibers.

Most types of hypertrophy are significantly more complicated than a simple increase in cell size (e.g., hypertrophy of cardiac myocytes is associated with changes in the pattern of gene expression that result in the reactivation of embryonic genes and alter the structure of contractile proteins and modify the density of hormone receptors).

Many other ocular tissues undergo hypertrophy as a precursor to replication, such as iris endothelial hypertrophy prior to the development of a preiridal fibrovascular membrane, corneal stromal fibroblast hypertrophy in the early stages of stromal repair, and lens epithelial hypertrophy at various stages of cataract formation.

type ii b fast-twitch muscle fibers are those used in a short sprint. t/f

Answers

True, type ii b fast-twitch muscle fibers are those used in a short sprint.

Which kind of fast-twitch muscle fibers are used in a brief sprint?

Fast twitch means that type II muscle fibers fire more quickly. Sprinting and heavy lifting are two exercises that recruit them since they are more potent than type I fibers and call for more intensity. Major strength is provided by these fibers, but they also exhaust more quickly than type I fibers.

Which muscle fibers are utilized for quick sprints?

Fast-twitch muscle fibers, or type II, are best known for them. For quick, powerful motions like sprinting, these muscle fibers are principally responsible. They do not, however, possess the slow-twitch fibers' capacity to increase endurance.

What part of a nerve cell helps maintain homeostasis inside each cell

Answers

The part of a nerve cell that helps maintain homeostasis inside each cell is the cell membrane.

The cell membrane, also known as the plasma membrane, is a thin, semi-permeable layer that surrounds the cell and acts as a barrier between the cell's internal environment and the external environment. It plays an important role in maintaining homeostasis, or stability, within the cell.The cell membrane is composed of a lipid bilayer, which is made up of two layers of phospholipids.

These lipids are arranged in such a way that the hydrophobic (water-repelling) tails face inward and the hydrophilic (water-attracting) heads face outward. This creates a barrier that prevents unwanted substances from entering the cell, while allowing necessary substances, such as oxygen and nutrients, to diffuse into the cell. Additionally, the cell membrane also contains proteins that act as pumps and channels, which help regulate the movement of ions and other molecules into and out of the cell.

Which substance is a product of cellular respiration but not fermentation?
A.ethanol
B.water

D.simple sugars

Answers

Water is a product of cellular respiration but not fermentation.

What is cellular respiration?

Cellular respiration is a metabolic process that occurs in the cells of living organisms to produce energy. It involves the conversion of glucose and other organic molecules into usable energy (in the form of ATP) through a series of chemical reactions. The process takes place in the mitochondria and can be broadly divided into two stages: glycolysis and the citric acid cycle (also known as the Krebs cycle). During glycolysis, glucose is broken down into pyruvate, releasing a small amount of energy in the form of ATP. In the citric acid cycle, pyruvate is further metabolized, generating more ATP and producing carbon dioxide as a waste product. Overall, cellular respiration allows cells to generate the energy they need to perform vital functions and sustain life.

For example, water is involved in the hydration and dehydration reactions that occur during glycolysis, which is the first stage of cellular respiration. In addition, water is a reactant in the citric acid cycle, where it helps to dissolve the various metabolites involved in the reaction and facilitates their movement within the cell.

when testing for light touch, what type of receptors will be triggered if you touch too firmly but without causing pain?

Answers

The type of receptors that will be triggered if you touch too firmly but without causing pain is pressure receptors or mechanoreceptors.

Receptors are specialized sensory cells that detect and respond to different types of stimuli such as light, sound, temperature, pressure, and chemicals. There are several different types of receptors, including: Photoreceptors, Auditory receptors, Thermoreceptors, Mechanoreceptors, Chemoreceptors, and Nociceptors.

Each type of receptor is specialized to detect specific types of stimuli and send signals to the central nervous system for interpretation and response.

Pressure receptors or mechanoreceptors are responsible for detecting pressure or vibrations in the skin and transmitting this information to the central nervous system. If the pressure is too strong, it will activate the pressure receptors and cause an increased sensory response, even though no pain is felt. This is why a light touch is important in these types of tests.

The stabilization of beta-sheet protein structures by hydrogen bonding:

Beta-sheet structures are a common secondary structure in proteins, formed by the alignment of beta-strands in an antiparallel or mixed parallel-antiparallel arrangement.Hydrogen bonding between the peptide bonds of distant residues on the same polypeptide chain can stabilize the beta-sheet structure by forming inter-strand hydrogen bonds.These hydrogen bonds can help to lock the beta-strands into position and prevent their unraveling, adding stability to the overall beta-sheet structure.The specific pattern of hydrogen bonding in a beta-sheet can also determine its overall shape and contribute to the unique stability and function of the protein.The hydrogen bonding network in beta-sheets can also help to create specific interfaces with other proteins or ligands, contributing to the function of the protein.Overall, hydrogen bonding is a critical factor in maintaining the stability and function of beta-sheet protein structures.

Diffusion is basically the net movement of particles from a region which is having higher concentration to a region having a lower concentration. Diffusion basically involves the net movement of molecules from one region to another till their concentration becomes equal.

This prevents the introduction of new genes into the newly isolated populations, which enables them to evolve in their own unique ways. In most cases, this is the result of a geographical barrier that has resulted in the population being split into two (or more) subpopulations.
