Answer:

Supporting us in the fact that fossil ferns have been found in Canada, we can conclude that: Canada once had a much warmer climate.

Explanation:

To understand this answer we need to analyze all the options.

1.- Canada once had a much warmer climate. This is correct because ferns only grow in environments with 73 and 86 Fahrenheit grades. Today Canada's temperature from 20 to almost 60 in general.

2.- Giant dragonflies once lived in Canada. Well, we can say that because we don't have information about dragonflies in our information. So it's incorrect.

3.- Canada was once covered by a giant sea. Well, we can't say that based on the information in the phrase. So it's incorrect.

4.- Dinosaurs once lived in Canada. The paragraph doesn't provide relevant information about dinosaurs, so it's incorrect.

Giant fossil ferns are evidence that life existed in the northern part of the region where it is usually cold. This would then suggest that before, some conditions were adaptable to some organisms compared to now.Thank you for your question. Please don't hesitate to ask in Brainly your queries.

Jet001 [13]

Answer: D. NE producing cell bodies are found in widespread brain regions

Explanation:

Norepinephrine (NE) is a chemical in the body that exists naturally and acts as both a neurotransmitter and a stress hormone. When the brain perceives that there has been a traumatic occurrence, it is released into the blood as a stress hormone.

Norepinephrine is produced in the inner part of the adrenal glands which also produces adrenaline.

Hence, NE is only found in inner part of the adrenal glands and the correct option is D.

Bald eagles have excellent eye sight. This adaptation helps them to find food.
They have long, sharp claws. This adaptation helps them catch and hold onto fish. They have curved beaks. This helps them to tear open the skin of their prey. They also have very few predators so this helps them to adapt and start their population.

A explanation for phenylketonuria

liraira [26]

Phenylalanine hydroxylase (PHA) performs an enzymatic function during the conversion of phenylalanine, to tyrosine. Existing naturally in several types of foods, for instance, breast milk, PKU is an essential α-amino acid and one of the plethora of amino acids used in the formation of proteins. Phenylalanine exists in three forms; L-phenylalanine, D-phenylalanine (mirror image of L-phenylalanine), and DL-phenylalanine which is a typic combination of D and L-phenylalanine, and unlike D and L- phenylalanine, is not found in foods. On the other hand, tyrosine, apart from being a derivative of phenylalanine, is a non-essential amino acid that forms part of the list of amino acids utile during the constitution of proteins. Ordinarily, lack of PAH leads to the accumulation of phenylalanine (the phenylalanine is not converted to tyrosine) leading to the development of a disease called Phenylketonuria (PKU).

Hope this helps!
