Answer:
The eyespot, the flagella and the chloroplast enhances the photosynthesis capability of chlamydomaonas.
Explanation:
generally eyespot is chlamydomans helps to detect the light. Flagella is a small motor like structure which helps to swim them towards the light. Chloroplast is most important for photosynthesis as it contains a pigment called chlorophyll, which is responsible for the green color of the leaves. it enhances the procedure of photosynthesis with the help of sunlight.
Geomagnetism is the study of the dynamics of the Earth's magnetic field, which is produced in the inner core. The Earth's magnetic field is predominantly a geo-axial dipole, with north and south magnetic poles located near the geographic poles that undergo periodic reversals and excursions.
Answer:
0.325 microliters
Explanation:
1 microgram = 1000 nanograms
DNA sample concentration= 1000 X 0.6 = 600 nanograms / microliters
We need a total of 50 microliter reactions, and the concentration should be 3.9 nanograms per microliter.
So, we need total 50 X 3.9 = 195 nanograms in 50 microliters.
Therefore, it required 195 / 600 = 0.325 microliters of DNA sample to be transferred.
The sympathetic nervous system releases hormones known as catecholamines which increase the heart rate.
<h3>What is a heart rate? </h3>
it is the number of contractions of the heart per minute.
<h3>What are catecholamines?</h3>
These are the neurotransmitters that have a catechol and a side chain that is an amine.
<h3>Which catecholamines are released by the sympathetic nervous system?</h3>
Epinephrine and norepinephrine are the catecholamines that are released by the sympathetic nervous system to increase the heart rate.
<h3>Where are these hormones released?</h3>
These hormones are released in the blood.
<h3>How does this hormone increase the heart rate?</h3>
- "These hormones are released at the neuromuscular junction of the cardiac nerves."
- "They shorten the repolarization period."
- This speeds up the rate of depolarization and contraction and thus the heart rate is increased.
