Answer:

The correct answer would be cerebrum.

In humans, cerebrum is the largest and principle part located in the anterior region of the skull. It is the main site for sensory processing, control and coordination of voluntary movements, language, learning and memory.

It can be divided into four lobes or sections namely:

  • Frontal lobe: It is associated with planning, reasoning, emotions, speech, movement, and problem solving.
  • Parietal lobe: It helps in controlling and coordinating orientation, movement, perception of stimuli, and recognition.
  • Occipital lobe: It helps in visual processing.
  • Temporal lobe: It is associated with memory, speech, perception and auditory stimuli.

I NEED HELP!!!<br><br> how can you survive a very cold winter
Rainbow [258]

Answer:

Prepare! Follow our winter survival kit checklist for tips on proper clothing, winter car kits, home supplies, and more.

Hypothermia and frostbite are the real dangers. Even in 50 F temperatures, you’re at risk of losing too much core and limb heat.

Protect your body heat. Protect it, trap it, and treat it like the precious resource it is.

Keep covered. Wind and exposure are the enemy. Exposed skin accelerates heat loss, especially through wind.

Dress in layers. The air trapped between each layer holds your body heat, like your own personal hot tub. Plus, layers give you better control over regulating body heat so you can avoid dangerous sweating.

Avoid sweating and stay dry. Besides moisture loss, sweating is bad because water on your skin makes you colder. That’s why we sweat to begin with — it’s the body’s air conditioning system.

Snow is an insulator. Don’t be afraid to use it for shelter.

Avoid eating snow. You lose a lot of core heat by melting snow inside your body. Melt it outside your body instead.

Alcohol does not warm you. Sorry, Russia!

Hydrate. Severe cold can be just as dangerous as severe heat. Stay hydrated.

Don’t travel unless you have to. Conserve energy. Stay where you’re most likely to be found. Especially if you’re in a nasty storm where navigation and shelter is difficult.

has four pairs of chromosomes what proportion of gametes would be expected to contain some chromosomes from both parental and ma
gogolik [260]

Answer:

To complete the question: a diploid organism has four pairs of chromosomes what proportion of gametes would be expected to contain some chromosomes from both parental and maternal origin? assume that there is no crossing over

Answer: 7/8

Explanation:

A diploid organism with four pairs of chromosomes...

Assume that the organism receives chromosomes A, B, C and D from the female parent and A', B', C' and D' from the male parent.

Proportion of gametes from patterns origin is the same as that of matters origin, this we have:

(1/2)^4 = 1/16 where 4 reps the number of possibilities, 1/2 rep the chance

Thus, the proportion of gametes expected to contain some chromosomes from both parental and maternal origin would be

(1 - (1/16 + 1/16)) = 14/16 = 7/8

The large intestine is the largest internal organ; its role is the absorption of food, nutrients and water.

Hepatic Cells - Hepatocytes have many metabolic functions that enable them to have a rich blood supply.All hepatocytes participate in metabolism. processing of proteins, fats, carbohydrates, bile color - bilirubin, bile acids, vitamins, minerals and some hormones. Food proteins broken down to their constituents - amino acids, are used by the liver as a building material for the synthesis of its own proteins and plasma proteins, which have different vital functions in the body.

In the small intestine, digested food is converted to liquid and goes to blood.

Pancreas secretes the enzymes amylase and lipase (which are mainly used to dissolve fats) and participates in the chemical breakdown of food to absorb molecules into the blood.
