Answer:
One million.
Explanation:
Each kidney contains about one million of nephrons. The nephron is the structural and functional unit of the kidney means that our kidney is made up of nephrons. The main function of nephron is to produces urine in the process of removing waste, toxic and excess substances from the blood. kidney is responsible for the filtration of blood by removing all the waste materials and taken these waste materials to the excretory organs in order to remove from the body.
Answer:
Photosynthesis doesn't occur at night. When there is no photosynthesis, there is a net release of carbon dioxide and a net uptake of oxygen. ... the rate of photosynthesis is higher than the rate of respiration. there is a net release of oxygen and a net uptake of carbon dioxide.
Answer:
The teeth in the mouth bite off a piece of food.
The teeth continue to break the food into smaller pieces.
Saliva rushes into the mouth and mixes with the broken-down food.
The food travels down the esophagus.
The muscles of the stomach churn the food and continue to break it down.
The broken-down food, called chyme, enters the small intestine.
The remaining food passes into the large intestine. Water is absorbed from the large intestine and the rest of
the material is stored as solid waste until it is excreted from the body.
Explanation:
Answer and Explanation:
All cells come from other cells. during cell division, the parent cells divide forming other cells. The cells prepare for division by multiplication of genetic material so that daughter cells will have the same number of chromosomes as the parent cell, synthesis of new organelles such as centrioles and mitochondria and building up of energy stores in form of ATP to drive the cell through the entire process.
T cells and B cells are the two main cell types that are crucial to the efforts of the adaptive immune response, in addition to cytokines and APCs.
<h3>Passive immunity is conferred by which of the following?</h3>
By supplying antibodies or lymphocytes that have already been produced by an animal or human donor, a vaccination may also impart passive protection. Most vaccines are administered parenterally (by injection), although some can also be taken orally or even nasally (in the case of flu vaccine).
Monoclonal antibodies search for and bind to the spike protein that protrudes from the coronavirus that causes COVID-19 after they have entered your body. Monoclonal antibodies that bind to the spike protein can prevent the virus from entering cells, slowing the infection.
The endothelial cell glycocalyx, which serves as a molecular sieve, and pressure gradients in the capillary beds both affect how lymph fluid is formed. toward with fluid propulsion
