Blood is essential for many organisms, such as humans and animals, for its important function of transporting substances (food, oxygen), vitamins, waste (carbon dioxide), hormones, etc. to all tissues and cells of the body.
1) Blood volume
If the blood volume increases ==> the blood flow increases.
2) Viscosity of blood
If we have an increase in blood viscosity ==> we have a decrease in blood flow
3) Peripheral Resistance
If there is an increase in peripheral resistance ==> the blood flow decreases
4) Diameter of blood vessels
If we have an increase in diameter of
blood vessels ==> decreased peripheral resistance ==> increased blood flow
5) Blood pressure
If the blood pressure increases ==> the blood flow increases.
6) In case of diseases
In the case of atherosclerosis or acute coronary syndrome ==> blood flow decreases.
7) Physical excercises:
During physical exercises ==> the heart rate increases ==> the blood flow increases.
Answer:
hypha
mycelium
fruiting body
spores
Explanation:
<em>A typical fungi thallus includes many filamentous hypha that combine to form mycelium that grows underground, and produce a fruiting body reproductive structure that produce spores that disperse on the wind to new habitat.</em>
Fungi body are generally made up of hypha, a network of which forms the mycelium. The mycelium grows underground within the substrate and occasionally bring out fruiting bodies which bear the sporangium containing the spores. The spores act as agent of dispersal and are used to form new organisms when the conditions are right.
Answer:
Jane: Aa
Matthew: aa
Explanation:
Jane is a heterozygous woman, which means that she is dominant for this genetic trait while Matthew is homozygous that did not inherit the achondroplastic dwarfism trait from his parents, that is why he is alive.
If we draw a Punnett square, we can see that some of their children will inherit the trait while others will not.

Vestigial structures are often homologous to structures that are functioning normally in other species. Therefore, vestigial structures can be considered the evidence for evolution, the process by which beneficial heritable traits arise in populations over an extended period of time.
If we had the same climate every minute of every hour tons of carbon would circulate the earth and climate change would make the polar ice caps melt from all the carbon around
