Answer:
Athletes who train short distances and explosive moments of extreme metabolic anaerobiosis have a higher percentage of fast fibers in the muscular structure of skeletal muscles, that is, in the muscles that achieve and carry out locomotion.
Some researchers also argue that men have a predisposition to have more fast fibers than women, since these are predominantly slow fibers.
Rapid muscle fibers to the leg muscle, generating more powerful contractions with less presence of oxygen and greater lactic acidification in the metabolism of the energy currency.
Explanation:
Fast and slow fibers are two different types of fibers, these are usually trained according to the histology or physiology of each athlete.
Those with the highest amount of fast fibers will train and perform better in high-power physical activities, that is, for short distances with little demand for oxygen.
Answer:
C.Autonomic
Explanation:
Autonomic is the peripheral part of nervous system.Autonomic help to think logically.It have two parts these are parasympathetic and sympathetic nervous system.
Autonomic controls lots of activity like breathing,sweating,digestion and shivering.We know that all our body action and reaction is controlled by our brain.
Mitotic division in onion root cells:
- Prophase: the emergence of chromatin threads that form chromosomes, the chromosomes are visible and overlap.
- Metaphase: chromosomes line up and line up in the middle of the equatorial plane. The centromere of the chromosome appears to have bonds with the kinetochores connected to the spindle threads.
- Anaphase: the centromere of the chromosome undergoes division then the chromosomes are pulled by the spindle threads towards the two opposite poles and leave the center of the equator that looks empty.
- Telophase: The cytoplasm divides into two identical-looking daughter cells. At the telophase stage, the process of cell division occurs in two parts and has identical properties.
Mitosis is a cell division through the stages of prophase, metaphase, anaphase, and telophase. The purpose of mitosis is for growth and regeneration which results in two daughter cells that are identical to the original parent cell. Mitosis occurs only once and lasts only during somatization.

Answer:
The ground tissue comprises the bulk of the primary plant body. Parenchyma, collenchyma, and sclerenchyma cells are common in the ground tissue. Vascular tissue transports food, water, hormones and minerals within the plant. Vascular tissue includes xylem, phloem, parenchyma, and cambium cells.
Cells, like humans, cannot generate energy without locating a source in their environment. However, whereas humans search for substances like fossil fuels to power their homes and businesses, cells seek their energy in the form of food molecules or sunlight. In fact, the Sun is the ultimate source of energy for almost all cells, because photosynthetic prokaryotes, algae, and plant cells harness solar energy and use it to make the complex organic food molecules that other cells rely on for the energy required to sustain growth, metabolism, and reproduction.
Cellular nutrients come in many forms, including sugars and fats. In order to provide a cell with energy, these molecules have to pass across the cell membrane, which functions as a barrier — but not an impassable one. Like the exterior walls of a house, the plasma membrane is semi-permeable. In much the same way that doors and windows allow necessities to enter the house, various proteins that span the cell membrane permit specific molecules into the cell, although they may require some energy input to accomplish this task
