Because water is so good at storing heat energy, it is harder for organisms to experience a change in body temperature in harsher climates.
Answer:
they start to run out of places to stay cool and then will eventually run out of food to eat then they will die. hope this helps
Answer:
How hard the blood pushes on the inside of the blood vessels is called Blood Pressure
The total amount of blood the heart pumps in one minute is called Cardiac Output
When blood vessels open wider during exercise, they are said to dilate
How many times your heart beats in one minute is called Heart Rate
The force that can put unhealthy tension on the heart as it is pumping is called Blood pressure
The amount of blood the heart pumps out in one beat is called Stroke volume.
Explanation:
All this concepts to the heart and cardiovascular system. It is important to know how heart is functioning to see how blood circulates.
Answer:
92 molecules
Explanation:
DNA or Deoxyribosenucleic acid is polynucleotide made up of several nucleotides containing the genetic information of an organism. In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA, tightly coiled many times around proteins called histones to support its stucture.
Human cells, like myself, contains 23 pairs of chromosomes (46 chromosomes in total). Each pair coming from each parent. Each chromosome is formed by two strands of DNA held together by hydrogen bonds forming the DNA double-helical structure. These two DNA strands form a base pair, which is a unit of two nucleotide bases bound to each other by hydrogen bonds. According to the complementary base pairing rule, Adenine (A) pairs with Thymine (T) while Guanine pairs with Cytosine (C).
Since there are 46 chromosomes in a diploid human cell and each chromosome consists of 2 DNA strands, then, there are 46 × 2 = 92 strands/molecules of DNA in each human diploid cell.
