Cardiovascular diseases involves the heart.
Any of the above options with regards to blood (etc, white blood cells, red blood cells) are related to circulatory system, not affecting the function of the heart.
Stem cells performing apoptosis to remove old cells is a myth. Stem cells can only differentiate to form cells of the same lineage, not causing other cells to undergo apoptosis. The only external factor that can cause cells to undergo apoptosis is a type lymphocyte in the immune system
Answer:
both can be found in all living things
Answer:
46 and 88° or 67 and 67°
Explanation:
An isosceles triangle has two sides of equal length and one other of a different length;
A triangle with such features also has 2 equal angles and one other;
If we consider that 46° is the angle that is not one of the two equal ones, then we can calculate the other two;
All angles in a triangle sum to 180, so:
180 - 46 = 134
The two remaining angles constitute 134° collectively;
If they are equal, each angle can be found like so:
¹³⁴/₂ = 67
Each of the two equal angles will be 67°;
Alternatively, if 46° is one of the two equal angles, then these two angles will be:
46 × 2 = 92
Then, the remaining angle can be found like so:
180 - 92 = 88
So the angles within the triangle are either:
46, 46 and 88°
or
46, 67 and 67°
