Two systems that work together to transport the sugar from food to the cells in the organism’s brain are digestive system and circulatory system.
<span>All carbohydrates from the food are broken down into glucose via enzymes from the mouth and small intestine. Absorption of glucose occurs in the microvilli of epithelial cells (small intestine). From there, glucose is transported directly into the bloodstream. Also, pancreas secrets the hormone insulin which makes cell permeable for glucose (via transporters).</span>

What does the sequence of DNA determine?
ArbitrLikvidat [17]

Answer:

It determines everything about you.

Explanation:

Sequencing DNA means determining the order of the four chemical building blocks - called "bases" - that make up the DNA molecule. The sequence tells scientists the kind of genetic information that is carried in a particular DNA segment.

The top layer of the brain, responsible for higher-level mental processes, is __________.
romanna [79]

The top layer of the brain, responsible for higher-level mental processes, is the neocortex because the neocortex comprises the largest part of the cerebral cortex, which makes up approximately half of the volume of the human brain. It is responsible for the neuronal computations of awareness, thought, perception, and episodic memory.

Therefore, The neocortex is the top layer of the complex brain that commands higher functions related to the mental processes such as cognition, sensory perception, and emotion. Although the neocortex consists of neuronal cell bodies or grey matter and unmyelinated fibers that surround the deeper white matter in the cerebrum, that helps for higher-level mental processes.

An individual who is heterozygous for two linked genes (with alleles A, a and B, b) is crossed with an a b/a b individual, and a
RoseWind [281]

Answer:

b) 0.30

Explanation:

An individual who is heterozygous for two linked genes (with alleles A, a and B, b)

i.e Aa & Bb × ab/ab

This cross produce the following offspring :

14 AB/ab  

36 Ab/ab  

34 aB/ab  

16 ab/ab

Now, the purpose of these calculation is to determine how close together on a gene (gene mapping) these recombinants are.

First, we need to determine the linked gene for the parental chromosomal configurations which are (Aa & Bb × ab/ab) and the recombinant configurations in the offspring which are ( AB/ab & ab/ab). This allows for the calculation of the recombinant frequency; and it is given by:  

= \frac{number of recombinant frequency}{total number of offspring}

=\frac{14+16}{14+36+34+16}

= \frac{30}{100}

= 0.3
