The rate at which blood flows through the human body changes in response to many factors. Which statement describes one of these

factors and its effect on blood flow?
A
A high viscosity of blood causes an increased resistance in the blood vessels and leads to slow blood flow.
B
A low blood pH decreases the rate of diffusion through the blood vessels and leads to slow blood flow.
C
The changing of the shape of red blood cells to a crescent shape decreases resistance and lead to a faster blood flow.
D
The narrowing of blood vessels increases pressure and leads to a faster blood flow.

Identify each adaptation as structural or behavioral adaptations.
Zina [86]

Answer:

Monkeys have a prehensile tail that allows them to grab and hold onto tree branches - structural

Moose make mating calls to locate potential mates - behavioral

Whales are covered in a thick layer of blubber, insulating their bodies in cold ocean waters - structural

Humans have five toes on each foot to help them maintain balance - structural

Many birds migrate south for the winter in search of food - behavioral

Explanation:

The structural adaptations are adaptations that help the organisms to survive in their environment through development of physical traits that give them an advantage. Such adaptations are the thick layer of blubber of the whales, the five toes of the humans, prehensile tail of the monkeys, rotational toe of the clouded leopard, long of the giraffe etc. The behavioral adaptations are adaptations that help the organisms to survive in their environment, but they manifested through their actions, not their physical traits. Such adaptations are the mating calls of the moos, the migration of the birds in winter, the hibernation of the bears etc.

Assuming that transcription and translation both proceed from left to right, which is the correct orientation of the DNA templat
aleksklad [387]

The correct answer is:

DNA template 3'– ……… –5'

RNA transcript 5'– ……… –3'

Protein product H2N– ……. –COOH

In nucleic acids, DNA and RNA 5’ end refers to phosphate group attached to the 5′ carbon of the ribose ring, while 3’ end refers to the ribose -OH substituent. Nucleic acids can only be synthesized in the 5′-to-3′ direction, which means that the DNA template is 3’—5’. Translation of the protein by the ribosome will also proceed in a 5′ to 3′ direction, which means that the mRNA template is 3’—5’.

The protein during the synthesis is extend from its N terminus toward its C terminus.

What is the relationship between the salinity and density of ocean water?
BartSMP [9]
Salinity and density share a positive relationship. As density increases, the amount of salts in the water—also known as salinity, increases. Various events can contribute to change in the density of seawater. Salinity can decrease from the melting of polar ice or increase from the freezing of polar ice.
