ANSWER:

The correct option is C: absorb fat to be transported back to the blood stream.

The villi absorb fats and fat-soluble vitamins that are essentially required by the body.

EXPLANATION:

Villi are small "finger-like projections" which are present on the "inner lining" of small intestine. The villi increase the surface area of the small intestine so that more nutrients can be absorbed from the food that is digested.

The centre of villi contains lymph capillaries and blood capillaries called lacteals. It is these lacteals that abort fats whereas the blood capillaries absorb water-soluble vitamins.

In a population of heffalumps, there is a single gene that controls the presence of hair. The H allele, which is a complete domi

<h2>Frequency of allele </h2>

Explanation:

Hardy Weinberg Equilibrium is used to calculate the allelic as well as genotypic frequency

Allelic frequency of dominant and recessive allele is represented by p and q respectively whereas genotypic frequency of dominant genotype is represented by $p2$ and $q2$ respectively

Given:

H allele (p) = hairy heffalump (dominant)

h allele (q) = hairless heffalump (recessive)

36% of heffalump population is hairless represents the % of recessive genotype, hh ( $q2$ ) =36%

Calculation of frequency of the h allele (q) :

Frequency of genotype hh ( $q2$ ) will be: 36/100=0.36 or 0.6*0.6

Frequency of h allele (q) will be 0.6

Mantle plumes are areas of hot, upwelling mantle and hot spots develops above these plumes as noted in the map above. Magma gene

harkovskaia [24]

The answer is C) extrusive igneous. This rock starts as magma, so you know it must be a type of igneous rock. The question tells you that the rock forms when it is cooled by the water, so you know it is formed outside of the Earth's interior, therefore making it extrusive igneous rock.

Which is the order of airflow during inhalation?

tigry1 [53]

Answer:

Nasal cavity, larynx, trachea, bronchi, bronchioles, alveoli.

Explanation:

The air travels through the respiratory system during inhalation in the next order:

Nasal cavity: You inhale air into your nose.
Larynx: The air travels down to this organ, a hollow, tubular structure that plays a key role in phonation, respiration, and deglutition.
Trachea: (Or windpipe) is a wide, hollow and cartilaginous tube that connects the larynx to the bronchi.
Bronchi: The trachea divides into two primary bronchi; they are the main passageway into the lungs.
Bronchioles: The bronchi develop smaller the closer they get to the lung tissue and are then consider bronchioles.
Alveoli: They are tiny air sacs located at the end of the bronchioles, which is the site of oxygen and carbon dioxide exchange in the respiratory system.
