Red blood cells are disc shaped. It is thought one factor that allows them to have this shape is because they do not have a nucleus. This tends to increase amount of space inside the cell for hemoglobin.
They have a flexible disc shape which helps increase the surface- to- area volume ratio which enables oxygen and carbon dioxide to diffuse across the red blood cell's plasma membrane more readily.
Their disc shape also enables them to squeeze through tiny capillaries that are half their size .
Answer: A terrestrial biome is a land biome (vs an ocean/lake/stream) biome.
Explanation: Abiotic factors could be all kinds of things. For example: wind, temperature, rainfall, ground water, humidity, amount of sunlight, soil composition, intensity of daylight, air pollution, noise pollution, etc.
Answer:
It takes the moon 29 days, 12 hours, 44 minutes, and 2.9 seconds to complete a rotation. It takes the moon 27 days, 7 hours, 43 minutes, and 11.5 seconds to go around the earth. The earth rotates counter clockwise as viewed from a north of the earth position.
The fact that Thapsigargin is a potent calcium atpase pump inhibitor means that the phase that will see immediate effects is the Relaxation period.
<h3 /><h3>Why does the Relaxation period get immediately affected?</h3>
Calcium ATPase pumps help the muscles to relax after contraction which means that Thapsigargin prevents this from happening.
It's effect will therefore be immediately felt in the relaxation period as muscles will be unable to relax.
Options for this question are:
a. Latent period
b. Contraction period
c. Relaxation period
d. All myogram stages are affected

Answer:
But in multicellular organisms, cells are grouped to form tissues. These tissues are specialised to carry out a particular function at a definite place in the body. For example, the muscle cells form muscular tissues which helps in movement, nerve cells form nervous tissue which helps in transmission of messages.
