Answer:
Almost all calcium in the body is stored in bones and teeth, giving them structure and hardness. Your body needs calcium for muscles to move and for nerves to carry messages between your brain and every part of your body.
Sodium-Potassium Pump
Three sodium ions bind to intracellular sites on the sodium-potassium pump.
A phosphate group is transferred to the pump via the hydrolysis of ATP.
The pump undergoes a conformational change, translocating sodium across the membrane.
Answer:
with haploid or diploid set of chromosomes. True
Explanation:
There are two types of cells in the body, haploid cells and diploid cells. The biggest difference is related to the number of chromosomes that each cell contains, while diploid cells contain two chromosomes (2n), haploid cells contain a chromosome (1n).
Features:
1. A haploid cell has only one set of chromosomes (n), while diploid cells have two sets of chromosomes (2n).
2. In humans, somatic cells are diploid, while gametes are haploid.
3. Diploid cells develop as a result of mitotic cell division, while haploid cells develop as a result of meiotic cell division.
4. Mitosis produces 2 identical daughter cells, where both stem and daughter cells are diploid. In meiosis, a diploid cell divides twice to produce 4 haploid daughter cells.
5. Humans and most animals are considered diploid organisms, while algae and fungi are examples of organisms that are haploid in most of their lives. Male bees, wasps and ants are also haploid.
Active transport is a cellular transport mechanism. It’s the movement of molecules that are assisted by enzymes along the way to a higher concentration.
Answer:
Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. For example, A larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all life forms. It keeps the "balance" in nature.
Explanation:
Answer:
This sample will absorb less energy because the more water, the harder it is to absorb all of the water. The other sample has less so the sand can absorb it more easily.
