Answer:
The amount of atmospheric oxygen is more than the amount of dissolved atmospheric oxygen in water.
Explanation:
The oxygen which is present in the atmosphere is much higher than the oxygen which is present inside the water. About 21 percent of oxygen is present in the atmosphere while only 1 percent of atmospheric oxygen is dissolved in the water. Oxygen is higher in atmosphere because this oxygen is used during respiration of organisms. If concentration of dissolved oxygen is very high, the marine animals die.

The sequential order of reproductive stage and fertilization starts with the
male and female sex cells being produces through meiosis. The male sex
cell which is the sperm is produced in the testes while the female sex cell
which is the egg is produced in the ovary.
During copulation, the sperm cells are released into the vagina which then
swims through the cervix and uterus to the fallopian tubes where the
fertilization occurs.
There is then movement of the zygote formed from the fertilization to the
uterus where development occurs.

First off, know that the whole division into kingdoms idea has been removed. All living creatures are now separated into domains: Bacteria, Archaea, and Eukarya. Still, I can provide a few for each category.
Monera is all the bacteria and archae bacteria in the world. They are all prokaryotes and therefore have no nucleus. Some examples are the certain diseases, such as Streptococcus pneumoniae (the bacteria that causes pneumonia) and Micobacterium tuberculosis (which causes tuberculosis).
Fungi are all the fungi of the world, all of which are eukaryotes that exist in both diploid and haploid stages. They include all the mushrooms of the world and molds like the bread mold, Rhizopus stolonifer.
Protists are extremely diverse, many being eukaryotes, though some are prokaryotes, and some being unicellular while others and multicellular. They are divided into three categories, protists (animal-like), which include Amoeba, algae (plant-like), which include Ulva, and fungus-like, which include chytrids.
Answer:
Slow freeze-quick thaw is lysis protocol used widely for mammalian and bacterial cells. It works by dehydrating the sample through crystal formation.
Explanation:
Slow Freeze - Quick Thaw:
- A cell lysis procedure that involves slowly freezing cells in dry ice or ethanol or even liquid nitrogen (-196°C) and then quickly thawing them at room temperature.
- Slow freezing involves cooling below freezing point to form ice crystals in the extracellular environment. As water around the cell freezes, the presence of high concentration of solutes (salt and sugar) and cryoprotective agents induces a hypertonic environment outside the cell. This forces water outside the cell, consequently dehydrating it. Crystals also form in the cell wall, disrupting the cellular transport.
- Upon quick thawing, as the extracellular environment turns hypotonic, water rushes into the cells which swell up and burst due to osmotic shock.
