Answer: The correct answer for the blank is-

Cartilaginous fishes.

Chondrichthyes is a class of cartilagenous fishes. This means that they have their entire skeleton system made up of cartilages ( unlike bony fishes whose skeleton is made up of bones) as they are devoid of true bones.

This class of fishes have exposed gills that is there is no preotection of gill slits ( unlike bony fishes, which have protective membrane over gill slits). They bear toothlike placoid scales.

Answer:

Adenine - Thymine

Guanine - Cytosine

Thymine - Adenine

Cytosine - Guanine

Explanation:

A goes to T, and vice versa. C goes to G, and vice versa. No matter how many times you flip a strand of DNA, A will always go with T and C will always go to G.

If it helps you, C and G are both curved letters and look very similar to each other. That's how I remembered that they went together. :)

Question # 9
weeeeeb [17]
Photosynthesis is a process by which plants use sunlight, water, and carbon dioxide to produce carbohydrates, and other biological compounds, which reduces the amount of carbon dioxide in the air. This is the difference between plants and animals. The carbon dioxide is stored in the plants until they decompose or are burned. So, for example, each fall when the trees lose their leaves and the plants die the level of carbon in the atmosphere goes up. The rest of the tree, bark etc., does not continue to absorb carbon. Plants only take in carbon so long as they are growing and not after they have reached their natural height. Planting trees and other plants is one component of the solution to global warming, but the number of plants we have now cannot consume more carbon than they already do, and there is some evidence that warmer temperatures make photosynthesis more difficult.

The correct answers are - In this example, the buzzer begins as the neutral stimulus and eventually becomes the conditioned stimulus. The buzzer initially is a neutral stimulus because it have no role to play in the blinking response. Eventually though through learned association the buzzer becomes a conditioned stimulus because you now associate it with a puff of air to the eye which in turn causes you to blink.
