a. 1/2 b. The organism is an animal
Explanation:
a. What is the medullary index for an organism that has a medulla width of 2cm and hair shaft width 4cm?
Medullary index = diameter of medulla/diameter of hair.
Given that diameter of medulla = medulla width = 2cm and diameter of hair = hair shaft width = 4cm,
Medullary index = diameter of medulla/diameter of hair = 2 cm/4cm = 1/2
b. Is this organism human or animal?
Since the medullary index = 1/2 > 1/3 (if it is ≤ 1/3 it is human hair and ≥ 1/2 it is animal hair), it is animal hair. So, the organism is an animal.
<h3>
Answer:</h3>
The generation of local currents.
<h3>
Explanation:</h3>
An action potential at the axon hillock generates local currents that depolarize nearby sections of axon to threshold. This change in membrane potential causes voltage-gated Na+ channels to open in the adjacent axon segment. This generates/regenerates the action potential in the adjacent segment, causing the action potential to propagate away from the axon hillock.
<h2>Answer:</h2>
<em>True.</em><em> Yes the sun is the ultimate source of energy.</em>
Explanation:
- We all living organism needs energy for their survival like for walking, talking and breathing.
- Energy is required by every cell for their reproduction, growth and maintenance.
- We all eat food to get that energy. Food is consists of plants and meat of some animal.
- These some animals also get food from plant.
- Plants take sun light to make their food/energy.
- Sun just provide energy in form of food. It dose not get energy from anywhere.
- Hence we all are ultimately depends on sun.
6 is true - scientists with a strong belief in what they are working on may show bias
7 is false - most plants and animals reproduce sexually
