Which part of an individual villus forms part of the lymphatic system and absorbs fats from the lumen of the small intestine?

1 answer:

7 0

I believe the answer is the lacteals.
Lacteals are structures that are in the middle of each villi; they are lymphatic capillaries that absorbs dietary fats in the villi of the small intestines. Triglycerides are emulsified by bile and hydrolyzed by the enzyme lipase, resulting in a mixture of fatty acids and monoglycerides. The lacteals merge to form larger lymphatic vessels that transport chyle to the thoracic duct where it is emptied into the blood stream at the subclavian vein.

A color-blind (X-linked recessive) human with Klinefelter syndrome has parents both of whom have normal color vision. 4a. From w

sineoko [7]

The extra X chromosome is received from mother.

<h3><u>Explanation</u>:</h3>

Klinefelter's syndrome is the condition of chromosomal aberration where the person has an extra X chromosome. This means the genotype of the person is 44+XXY and the total chromosome number is 47. This condition is achieved due to inappropriate meiotic division and one of the sperm or ovum has the an extra X chromosome.

Here both the parents are normal in terms of colour vision. So the father cannot have the gene of colour blindness because if it was present, then father would have been colour blind because he has only one X chromosome per cell. So its present in mother who is heterozygous in terms of colour blind gene. So the extra X chromosome also came from her which made the presence of two defective X chromosomes in the offspring and made it colour blind.

1)The picture is an aerial view of what and what type boundary forms this feature?

melamori03 [73]

Answer:

The correct answer is - aerial view of the fault line of San Andreas which represents a transform or strike-slip type of boundary.

Explanation:

The picture is given in the question is an aerial view of the fault line of San Andreas.

A fault is a planar break or intermittence in a volume of rock across due to rock-mass movement that leads to significant relocation or displacement. In San Andreas, the faultline represents the transform or strike-slip type of boundary.

Observation:

A complex zone of crushed and broken rock

Many smaller faults branch

A population in which the frequency of alleles remains the same over generations is said to be in genetic equilibrium. Describe

DochEvi [55]

Answer:

Natural selection disrupts the genetic equilibrium by favoring the genes for the traits that impart survival advantage to individuals.

Explanation:

Natural selection refers to the unequal survival rate of individuals of a population due to the presence of some beneficial adaptive genetic trait. These individuals are able to survive more and leave more progeny. Over generations, the population has increased number of these individuals leading to evolution of a population with different allele frequencies.

For example, the frequency of gene for antibiotic resistance in the bacterial population was increased once humans started using antibiotics to control the bacterial population. This led to the evolution of the bacterial population with antibiotic resistance.
