(TRUE OR FALSE) comparative anatomists can compare only the body structures of species that currently exist on this planet
false. the answer is false
identify any four organelles that should be present in the eukaryotic organism and describe the function of each organelle
In what part of cell cycle does dna replication take place what is the duplicate copy called
What is the purpose of natural selection
to keep life going even as the environment changes
What process releases carbon dioxide back into the air
The lungs deliver a regular supply of oxygen to the blood. Which is in turn circulated to most all the cells of the body. At the same time oxygen is consumed during aerobic cellular respiration within these cells. This implies that?
This implies that oxygen will passively diffuse into the cells.
The diffusion of oxygen into the cells undergoes passive diffusion (the movement of a molecule through a cell wall across a concentration gradient without the use of energy). During respiration, oxygen molecules move from where there is a higher concentration (such as the air in the lungs) to where there is a lower concentration.
There occurs passive diffusion of oxygen from blood into the cell
This implies that cells take oxygen supply from the blood . The cellular plasma membrane is a permeable membrane that has controlled regulatory mechanism to allow diffusion of oxygen across the cell membrane.
This diffusion mechanism is passively driven from region of high oxygen concentration (outside the cell or in the blood (body fluid)) to regions of low oxygen concentration (with in the cell membrane)
A homozygous dominant mother and a homozygous recessive father have two children. Show genetic cross and What is the probability that the children are lactose intolerant?
Four forces are being applied to move an object to the left. Force 1 is pushing to the right at 200 N. Force 2 is pushing to the left at 500 N. Force 3 is pushing to the right at 100 N. Force 4 is pushing to the left at 50 N. What's the net force acting on this object?
Net force is 250 N and it act in right direction.
It is given that, four forces are being applied to move an object to the left. Let the force acting on the left is F. Force 1 is pushing to the right at 200 N. Force 2 is pushing to the left at 500 N. Force 3 is pushing to the right at 100 N. Force 4 is pushing to the left at 50 N.
So, net force acting on left is : F + 500 N +50 N
Net force acting right is : 200 N + 100 N
F = -250 N
So, the net force acting on the object is 250 N in the right direction.
