Air temperature: When temperatures (and the humidity) soar, the heart pumps a little more blood, so your pulse rate may increase, but usually no more than five to 10 beats a minute.<span>Body position: Resting, sitting or standing, your pulse is usually the same. Sometimes as you stand for the first 15 to 20 seconds, your pulse may go up a little bit, but after a couple of minutes it should settle down. Emotions: If you’re stressed, anxious or “extraordinarily happy or sad” your emotions can raise your pulse. </span><span>Body size: Body size usually doesn’t change pulse. If you’re very obese, you might see a higher resting pulse than normal, but usually not more than 100. </span><span>Medication use: Meds that block your adrenaline (beta blockers) tend to slow your pulse, while too much thyroid medication or too high of a dosage will raise it.

Explain how the result of meiosis and cytokinesis affects inherited traits
Anna71 [15]

Answer:

Meiosis is a type of cell division in which a single cell is divided into four daughter cells having half number of chromosome while cytokinesis is the division of cytoplasm.

Meiosis occurs only in sex cells which are responsible for the formation of new organism. Traits are transferred from parents to the offspring through the process of sexual reproduction. In sexual reproduction, sex cells i. e. sperm cells of male fuse with egg cell of female forming a zygote which turns into a new organism and traits are transferred from one generation to another.
