<h2><u>Answer:</u></h2><h3><u>Question 1:</u></h3>
The correct option is A (a curved path)
Explanation:
Their way is diverted by the revolution of the earth. This is the Coriolis impact. This is the motivation behind why wind streams on the northern side (north half of the globe) turn counter-clockwise and that blows south of the equator, the southern side of the equator, turn clockwise.
<h3><u>Question 2:</u></h3>
The correct option is B (forms at or near the ground)
Explanation:
Fog is an obvious vaporized comprising of modest water beads or ice precious stones suspended noticeable all around at or close to the Earth's surface.
Haze can be viewed as a sort of low-lying cloud, more often than not taking after stratus, and is vigorously impacted by adjacent waterways, geology, and wind conditions.
<span>The correct option is: IT HELPS CARRY AN IMPULSE BACK TO THE NEXT NEURON. There are two types of neurons, excitatory and inhibitoty neurons. Both serve to transmit impulse from one point to the other. Each neuron usually makes several connections with other cells.</span><span />
Glucagon. It stimulates the liver to convert stored glycogen to glucose.
Usually if your pulse rate is thumping at a fast pace that means you have been running or your body has been actively moving in some type of way.
Answer:
a. p53 activates transcription of WAF1.
Explanation:
<u>WAF1 transcription occurs independent of p53 during oxidative stress so p53 does not play any role in cell cycle arrest in the signaling pathway which involves WAF1 . </u>
In rest of the mentioned options, p53 plays a role directly or indirectly. During double stranded lesion in DNA in G1 phase, a sensor protein known as ATM binds the DNA lesion site. ATM is a serine/threonine kinase which phosphorylates another kinase known as chk2. After phosphorylation,<u> chk2 stabilizes transcription factor p53.</u> p53 further acts as a transcription factor for the synthesis of a protein known as p21 which inhibits G1 phase specific CDK and ultimately cell is arrested in G1 phase. The cell remains in arrested state until the DNA lesion is fully repaired. <u>Hence, p53 indirectly blocks G1 to S transition with the help of p21. </u>
As such <u>WAF1 transcription factor involving pathway</u><u> </u><u>also requires p21 protein for causing cell cycle arrest but in this pathway p21 is not synthesized with the help of p53. </u>
