Answer:
Here is the full question:
(A) If a closed container contains a mouse as well as enough food, water, and oxygen for the mouse to live for 3 weeks,
How much will the container weigh 1 and 2 weeks later after the mouse has eaten, drunk and exercised (respiration is CO2 emission), and why?
(B) If the mouse was in a wire cage and only the weights of the mouse, food, and water were considered, would you come to the same answer as in (A) and why?
Explanation:
(A) The mouse will weigh the same. This is because solids, liquid, and gases cannot escape the closed container. All of the life processes involving reactions conserve the atoms involved. Some of those atoms will appear in the form of gases, some as solids, and others as liquids but all will be retained in the closed container.
(B) In a wire cage, gases can escape. This means that the weight will not be the same after 1 and 2 weeks. The weight would be less than the original weight of the mouse, it's food, and it's water.
Answer:
Answer: Desert mole excretes concentrated urine with urea. Marine fish excretes urine with uric acid. Tilapia excretes dilute urine with amino acids.
They are located in the liver the wall of the sinusoids.
Answer:
The answer is A) You would find 46 chromosomes in a Haploid cell and B.) You would find 23 chromosomes in a Diploid cell.
Explanation:
A human haploid cell, such as a skin cell, is a complete unit. It is capable of duplicating itself and the new cell has exactly the same number of chromosomes, which is 46.
A human diploid cell, such as a human egg cell, has half the number of chromosomes, which is 23.
Hope this helps!! Have an Awesome day!!! :-)
Archaea have more complex RNA polymerases than Bacteria, similar to Eucarya. Unlike bacteria, archaea cell walls do not contain peptidoglycan. Archaea have different membrane lipid bonding from bacteria and eukarya. There are genetic differences.B
