It IS possible, but very unlikely. This punnet square shows that it would have 1 in 72 chances for all of the doggies to have the spot.
TRUE DAT.................
Living organisms obtain many of their requirements by diffusion. They also get rid of many of waste materials in this way. For example, Plants need carbon dioxide for photosynthesis. This diffuses from the air into the leaves through the stomata. It does this because there is a lower concentration of carbon dioxide inside the leaf as the cells are using it up. Outside the leaf in the air, there is a higher concentration. Carbon dioxide molecules therefore diffuse into the leaf down this concentration gradient :)
I hope u understood!
Answer:
B. All good choices are cancelled out by functional fixedness.
Explanation:
People usually follow their strongest internal feeling despite their rational understanding So I feel it’s B for example someone dies in a shoot out I would in the situation mourn but some else would probably be so overwhelmed by there emotion of anger they’ll want revenge asap and end up same as there friend.
Adrenaline helps in emergency situation by providing energy so that the major muscles of the body can respond to the perceived threat.
In danger, the brain then sends nerve impulses to the adrenal gland in the kidneys. When the nerve signal reaches the adrenal gland, chromaffin cells, in the medulla of the adrenal gland, release epinephrine or adrenaline. It then enters the bloodstream. It is thus carried around the body to cells in various locations, where it initiates several responses.
1. Adrenaline, along with another hormone called glucagon, is responsible for the breakdown of glycogen in liver cells. Glycogen is a form of energy storage. This gives energy to the muscles
2. Adrenaline effects the skin also. Restriction of the arteries is caused by the binding of epinephrine/adrenaline to some alpha-adrenergic receptors. This cuts off blood supply to the skin. This results in the contraction of the smooth muscle cells in the skin, which cause the raising of the hairs on the surface of the skin.
3. The lungs contain smooth muscle. Epinephrine causes smooth muscles to relax. Specifically, epinephrine binds to beta-2-adrenergic receptors on bronchiole muscle cells. This allows the bronchioles to relax, which enables intensified respiration.
