Plants get their energy from the sun using Photosynthesis and animals get it from eating food.
<h2>Urea </h2>
Explanation:
Urea is a small nitrogenous compound which is the main end product of protein catabolism in mammals
- Urea is a nitrogen-containing substance normally cleared from the blood by the kidney into the urine
- It is made predominantly in the liver from ammonia and bicarbonate and is one of the main components of urine
- The rate of synthesis varies from 300 to 600 mmol/day depending on the protein intake
- All of this urea eventually finds its way into the urine
- Because urea makes up a large part of the obligatory solute excretion, its osmotic pressure requires significant volumes of water to carry the urea
- Urea passively crosses biological membranes, but its permeability is low because of its low solubility in the lipid bilayer
- Some cells speed up this process through urea transporters, which move urea by facilitated diffusion
- Urea is passively reabsorbed in the proximal tubule, but its route of transport is not clear
- Urea transporters have not yet been identified for the proximal tubule
The double membrane. It's theorized that chloroplasts used to be their own single-celled organism in the environment (and therefore with its own membrane). Then, the theory states, a larger cell took in the chloroplast by endocytosis, which involves surrounding the chloroplast in the large cell's own membrane. The chloroplast would then have two membranes surrounding it. This is similar to the thinking for mitochondria becoming an organelle as well. Hope this helps! :)
Taenia saginata/Taenia solium are commonly known as tapeworms is a <u>true</u> statement.
Explanation:
Tapeworms are long segmented parasitic flatworms which reside in the intestines of the host’s body. They belong to the phylum Platyhelminthes and scientifically called the Cestoda.
Tapeworm belonging to the Taenia species like the T. saginta, T. solium, T. asiatica etc causes parasitic infections called Taeniasis in the human body and affects the intestines.
Taenia saginata is the tapeworm which resides in pork and Taenia soleum resides in beef.
Humans can be infected with tapeworms when raw or improperly cooked pork or beef is consumed
