I can’t help you with the first two questions, as I do not have a reference, but I can help you with the last two. Cystic fibrosis is a recessive trait. It is caused when specific sections of both copies of chromosome 8 are deleted, which in other words mean that it is not a sex-linked disorder because it isn’t inherited from the mother and father of the offspring.

No, all mutations are not bad. Only a small amount of mutations cause genetic disorder. Some in fact are good mutations. There is actually one mutation that is found roughly in 10% of Europeans which affects the CCR5 protein and it prevents HIV from entering the cell!

What are the similarities and differences between the water and carbon cycles?
Misha Larkins [42]

Insectivorous birds are more likely to eat medium sized insects because the exoskeleton of large insects is too hard to break, a
andrey2020 [161]

Answer:

Option A: True

Explanation:

Insectivorous birds such as bluebirds, dippers and flycatchers prefer to eat medium-sized insects. This is because like most birds, they love easy and satisfying meals. To the birds, a medium-sized insect is a good compromise because it is quite easy to chew and digest and at the same time, easy to find.

As a result, most insectivorous birds prefer to get their daily ration of proteins from the medium-sized birds.

A fox is a type of mammal that is related to dogs. How does a fox most likely respond to hot air temperatures in a way that ecto
sveta [45]

Answer:

By panting or breathing heavily.

Explanation:

<em>An ectothermic animal is one whose body temperature depends on the temperature of the external environment.</em>

The body of ectotherms regulates temperature depending on the temperature of the external environment where such animal finds itself.

Hence, when the temperature of the external environment rises as a result of hot air, the body of an ectotherm (that is homeothermic, that is, maintain a relatively constant body temperature irrespective of the temperature of the external environment) will adjust so as to keep its temperature relatively constant.

Dogs generally pant (breathe heavily) to bring their body temperature back to normal whenever it rises beyond normal due to rigorous physical activities or high external temperature.

<em>Hence, a fox will most likely pant in response to hot air temperature just like dogs.</em>

What are two other abiotic factors that could also be studied to help determine the health of the streams in the two watersheds?
Marta_Voda [28]

I'm not completely sure about this answer because our unit on that was very short. So please don't be upset if its incorrect.

The answer is phytoplankton and water depth, because in order for any ecosystem to survive they need the producer population (Plants)
