Answer:

The lion's mane jellyfish's skin is so thin that the body receives oxygen through difussion.

Explanation:

The lion's mane jellyfish - giant jellyfish - is the largest species of jellyfish.

This species does not possess a 'usual' respiratory system that would enable to deliver oxygen to its cells. Instead, <u>the lion's mane jellyfish's skin is so thin that the body receives oxygen through difussion. </u>

Thanks to diffusion (<em>oxygen molecules moving from an area of high concentration to an area of low concentration</em>), oxygen that is already dissolved in the ocean then is converted into an equal amount of oxygen inside the jellyfish.

Different forms of a given gene are known as
yulyashka [42]

Answer: alleles

Explanation:

Alleles are different forms of a given gene. Alleles are mutated forms of a given gene which controls a particular trait. For instance, the gene that codes for hemoglobin is denoted with the letter A but the gene has another variant denoted by S. In abnormal hemoglobin S (sickle hemoglobin), glutamate is replaced by valine at position 6 in the amino acid sequence of the two beta chains of hemoglobin. This change in the amino acid sequence causes the red blood cells to have a sickle shape resulting in sickle cell disease. Therefore hemoglobin A and S are alleles of a given gene.

A 154-lb adult man performs a moderate level of physical activity and regularly consumes 2700 Calories a day. State whether the
Arte-miy333 [17]

Answer:

The correct answer would be - remain the same.

Explanation:

In the given table showing the average daily calories requirement according to the weight of the adult men. Which is as follows:

weight                daily intake

132                        2250

154                        2450

176                        2650

198                        2850

220                       3050

242                       3250

In this, the highlight weight and required calories should be taken by the man who does not perform any physical exercise but according to the question a man with 154 lb perform a moderate exercise, and according to the CDC a 154 lb men can burn anywhere between 140 and 295 calories in 30 minutes by moderate exercise for an hour.

Thus, the total calories he takes: 2700

burn by exercise: 295

should take: 2450

then = 2700 - (2450+295)

= 50 calories over the limit that will have negligible effect on the weight.
