Carbohydrates are the sugars, starches and fibers found in fruits, grains, vegetables and milk products. Though often maligned in trendy diets, carbohydrates — one of the basic food groups — are important to a healthy diet.

Which causes acid precipitation?
max2010maxim [7]

Answer:

D - sulfuric acid

Explanation:

Sulfuric acid is the chief offender in the acid precipitation formation. Sulfur dioxide is delivered from nitrogen oxides and power plants which come from car exhaust. When this pollution enters the atmosphere, they can explore hundreds of miles until they combine with the moisture in the environment which further forms the acids that ultimately reach the surface of the earth and cause damage.

Bottlenecks and founder effects

Genetic drift can cause big losses of genetic variation for small populations.

Population bottlenecks occur when a population's size is reduced for at least one generation. Because genetic drift acts more quickly to reduce genetic variation in small populations, undergoing a bottleneck can reduce a population's genetic variation by a lot, even if the bottleneck doesn't last for very many generations. This is illustrated by the bags of marbles shown below, where, in generation 2, an unusually small draw creates a bottleneck.

Reduced genetic variation means that the population may not be able to adapt to new selection pressures, such as climatic change or a shift in available resources, because the genetic variation that selection would act on may have already drifted out of the population.

Elephant seal

 

An example of a bottleneck

Northern elephant seals have reduced genetic variation probably because of a population bottleneck humans inflicted on them in the 1890s. Hunting reduced their population size to as few as 20 individuals at the end of the 19th century. Their population has since rebounded to over 30,000 — but their genes still carry the marks of this bottleneck: they have much less genetic variation than a population of southern elephant seals that was not so intensely hunted.

Founder effects

A founder effect occurs when a new colony is started by a few members of the original population. This small population size means that the colony may have:

reduced genetic variation from the original population.

a non-random sample of the genes in the original population.

For example, the Afrikaner population of Dutch settlers in South Africa is descended mainly from a few colonists. Today, the Afrikaner population has an unusually high frequency of the gene that causes Huntington's disease, because those original Dutch colonists just happened to carry that gene with unusually high frequency. This effect is easy to recognize in genetic diseases, but of course, the frequencies of all sorts of genes are affected by founder events.

In a motor reflex , such as the patellar tendon reflex, afferent action back to the spinal cord is mediated through which of the
brilliants [131]

Answer:

The correct answer will be option-B.

Explanation:

The patellar tendon reflex is the kicking movement of the lower leg in response to the tap on patellar cap used to test the L2, L3, and L4 segments of the spinal cord in the body.

The spinal cord interacts with muscles through muscle sensors called muscle spindle which signals after the stretching of the muscle. The signals are sent to the spinal cord through afferent neurons or sensory neurons which starts the reflex action to prevent overstretching of the muscle.

Thus, Option-B is the correct answer.
