Answer:b) The air at high altitudes are less dense, so its harder to breathe.
Explanation:
AS altitude increases, the air pressure drops. This reduces the amount of gas molecules in the air so the air becomes less dense compared to air closer to sea level.

a

b
Breaking down glucose gives off energy
c
Breaking down ATP gives off energy
d
1 ATP has more energy than 1 glucose
Answers
Answer:
D is false
Explanation:
D is false because after breaking down 1 glucose, around 36-38 ATP will be produced from ADP
A is true because cells use ATP for work
B is true, as breaking glucose makes ATP, which is just stored energy
C is true too, since ATP is an ADP connected to a phosphate. This bond contains energy and detaching the phosphate will power parts of the cell, for instance active transport systems.

Answers
Answer:
From other seeds
Explanation:
They grow more seeds form the one seed
Answer:
From plant reproduction.
Explanation:
Plants produce flowers to make seeds. To make a seed a flower must be pollinated. Pollen from the male part of one flower travels to the female part of another flower where the seeds are made. Most, but not all plants, have both male and female parts inside one flower. The stigma is usually in the centre and the stamens, which produce the pollen, cluster around it. The petals act like an advertisement to attract various animals, which will carry the pollen from one flower to another.

when preparing pure cultures, dilution is necessary for
Answers
Dilution is necessary during pure culture preparation to reduce the bacterial load and allow readable colonies to grow.
Dilution of bacteria culture is carried out in comparison to McCfarlan standard so as to have a decent number of bacteria that will not be too numerous or too little to observe the growth of distinct colonies during culture preparation.
Without dilution, colonies may form but may be too numerous to count. Too much dilution may also lead to no growth in the culture plates.

what solution, (hypertonic, hypotonic, isotonic) would make osmosis go faster?
Answers
Answer:
Explanation:
Osmosis is the movement of WATER molecules across a semipermeable membrane (such as the cell membrane) from where there is a high concentration of water to where there is a low concentration of water. The interior of a living cell consists of cytoplasm, which is a solution of mostly water with dissolved substances such as salt.
Now for the fun stuff! An Isotonic solution is a solution that has the same concentration of dissolved substances as is found inside the cell. If a cell is surrounded by isotonic solution, then there is no net movement of water across the membrane by osmosis, because the concentration of water is the same on both sides of the membrane.
A hypertonic solution is a solution with a higher concentration of dissolved substances than is found inside the cell. If a cell is surrounded by hypertonic solution, then water will move OUT of the cell by osmosis because there is a higher concentration of water inside the cell compared to outside (where there is lots of dissolved salt, etc.) A cell in hypertonic solution will shrink.
A hypotonic solution is a solution with a lower concentration of dissolved substances than is found inside the cell. If a cell is surrounded by hypotonic solution, then water will move INTO the cell by osmosis because there is a higher concentration of water outside the cell compared to inside. A cell in hypotonic solution will swell up and, if there is no cell wall, may burst. A silly but simple way to remember that water moves into a cell in hypotonic solution is that "hypo causes the cell to swell up like a hippo"

What is a lymph node?No lymph nodes exist in the central nervous system. The lymph nodes are more likely to gather in three locations on each side of the body.
The inguinal nodes in the groin, axillary nodes in the armpit, and cervical nodes in the neck are where these sites are found.
The typical lymph node is enclosed by a connective tissue capsule, which divides it into lymph nodules. The lymph nodules, which are dense aggregations of lymphocytes and macrophages, are divided by lymph sinuses.
Therefore, there are several locations throughout the node's perimeter where afferent lymphatics, which carry lymph there from the periphery and enter the node on its convex side, may be found.
