False

Cardiovascular disease can result from your genes and/or your environment (diet, etc), so, proper diet and exercise alone cannot entirely prevent disease. However, it can greatly lower your risk of getting it and/or prevent its symptoms from negatively affecting your life.

False,

a lot of things can be prevented but then many aren't preventable. if you have this disease them blame your family they probably gave it to you.

In labrador retrievers, a common breed of dog, black coat is dominant to chocolate, normal vision is dominant to progressive ret
marshall27 [118]
The data given regarding the alleles are as follows
black(B)-dominant , chocolate(b) - recessive
normal vision - dominant, progressive retinal atrophy - recessive 
normal hip joint - dominant, hip dysplasia - recessive 

lets first consider one trait 
parents are heterozygous 
when crossed            Bb         x          Bb
offspring               BB      Bb     Bb     bb
                             --------black-----  chocolate
the probability of dogs being black - 3/4
                           dogs being chocolate - 1/4
likewise for the other two traits 
probability of normal vision - 3/4 and retinal atrophy - 1/4
probability of normal hip joint - 3/4 and hip dysplasia - 1/4

we have to calculate the probability of 1st pup being born is
chocolate - 1/4 
normal vision - 3/4
normal hip - 3/4
since all these traits should be acquired the probability of having the above three traits is calculated by getting the product of individual probabilities 
therefore answer is 1/4 x 3/4 x 3/4
  probability              = 9/64

Recall that the ability to maintain a stable internal environment in spite of changes in the external or internal environment is
muminat

Answer:

Homeostasis

Explanation:

Homeostasis is a mechanism of the body which involves negative feedback loops that helps the body to maintain a stable internal environment when there is an external or internal change.

An example of homeostasis in the human body is the regulation of the internal temperature of the body. When there is a change in the normal body temperature, for example, if your temperature drops sharply below 37 degrees Celsius, homeostasis kicks off in the body to maintain the normal body temperature. Homeostasis uses thermoregulation mechanism which triggers shivering to raise the body temperature in an attempt to return it back to normal.

Homeostasis also makes it possible for the body to maintain the balance of water and other substances in the body like calcium in our body. For example, when the calcium level drops below normal level, the parathyroid gland secretes hormone which helps in the increasing of blood calcium levels.  

Homeostasis s a essential mechanism that helps keeps the body in a balance and functional state.

What physical health risks are directly associated with urban sprawl?​
spin [16.1K]

Answer:

The risks of various pollution and infections increase with urban sprawl.

Urban sprawl can be described as a condition in which the people from urban area migrate to low residential areas due to which the city starts to expand more in size.

During urban sprawl, more water contamination is likely to be caused as the water available cannot support such a large number of migration. There is not proper sewage system due to which contamination arise and cause sickness in the people. Also, these areas have more pollution due to traffic jam situations which causes sickness.

Organisms are classified as either a prokaryote or a eukaryote based on their _______.
Mrac [35]

Answer:

The classification of organisms as either a prokaryote or a eukaryote is based on the structure of the organism's cell nucleus

Explanation:

The etymology of the word 'karyote' in both 'prokaryote' and 'eukaryote', is derived from a Greek word that explains the nucleus.

An organism having a true nucleus (i.e a nucleus surrounded by a nuclear membrane) in its cell(s), is classified as a eukaryote.

'Eu' in the word 'eukaryote', is derived from a Greek word that means 'true'.

A prokaryote is an organism that lacks a definite nucleus, hence, having its genetic materials suspended freely in the cyoplasm without a special nuclear membrane enclosing it, aside from its plasma membrane.
