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
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.
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.
Electric Power
Because Eletric Things Dont Need Oil
Electricity Is Made Up Of WIres Which Is How We Get Our Electricity
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.
