Answer:
Doing experiments, maintenance and cleaning.
Explanation:
Astronauts perform tasks of the day which is supervising experiments, performing routine maintenance on station equipment and the astronauts wipe the walls, floors, and windows to keep them clean in order to avoid any type of microbial growth. Most of the activities are similar in space to the earth i.e. sleeping, eating the meal three times a day and exercise to maintain health and become active all the day.
1. The "Law of Inertia" An object will keep doing what it's doing unless a force acts on it.
2. F = ma
3. Every force has an equal and opposite reaction
Answer:if you raise the points to 25 i will do everything with evidence etc.
Explanation:
Answer:
A. If seed shape did not have a clearly recessive form
Explanation:
To study inheritance patterns, Mendel studied a few characteristics of pea plant -e.g. pea colour, shape, plant height. These characteristics had to be very clear dominant and recessive forms to distinguish between, otherwise detecting the patterns would not have been obvious.
For example, if crossing a wrinkled seed plant with a smooth seed plant made a semi-wrinkled plant, Mendel would not have been able to study the inheritance of dominant and recessive traits.
Answer:
Here, we have a composition passage and we are required to fill in the with missing words. The missing words are highlighted in bold format and underlined.
Lecithins and cephalins are both <u>glycerophospholipids;</u> they consist of <u>glycerol</u> with fatty acids forming <u>ester</u> bonds with the first and second <u>hydroxyl </u>groups. The third <u>hydroxyl</u> group of the <u>glycerol </u>forms a<u> phosphate bond </u>with phosphoric acid, which forms another<u> phosphate </u>bond with an amino alcohol. In lecithins, the amino alcohol is <u>choline;</u> in cephalins, the amino alcohol is usually <u>ethanolamine. </u>
Explanation:
Lecithin is a chemical complex composed primarily of fatty acids, glycerol, phosphoric acid, and choline. It can be present in egg yolks, soybeans, sunflower seeds, and plant seed cells and is completely normal. Soybean and sunflower lecithins contain much more important fatty acids than rapeseed lecithin, making them nutritionally more useful.
Phosphatidylethanolamine, also known as cephalin, is a phosphoglyceride that, like phosphatidylcholines and lecithins, is a component of biological membranes. A glycerol residue esterified by two fatty acids and a phosphoethanolamine residue gives rise to phosphatidylethanolamines. They're made by combining CDP-ethanolamine with diglycerides and releasing a CMP molecule. Phosphatidylcholines are formed when S-adenosylmethionine methylates the amine in ethanolamines. They're mostly found in the inner layer of plasma membranes' lipid bilayers.
