Answers

The cerebral cortex process the information delivered by the thalamus, the information is related to the senses.

The only system that does not pass through the thalamus on its way to the cerebral cortex is the olfactory system.

The systems that pass through the thalamus are:

1. The visual sensation or information passes through the visual occipital cortex. It then delivers the information from the thalamus to the cerebral cortex.

2. The gustatory cortex is the region of the cerebral cortex, which is responsible for the senses of tastes and flavor. It also passes through the thalamus on its way to the cerebral cortex.

3. The tactile system includes the senses of touch. It is the information received through the receptors present on the skin. It also delivers the information to the cerebral cortex via the thalamus.

4. The olfaction system is not involved in the thalamus pathway. The olfactory cortex is present in the temporal lobe, which is not routed through the thalamus.

Thus, the correct answer is Option C.

1. What percentage of the offspring will be heterozygous?
2. Why does each parent contribute only one allele to the offspring?

Answers

Answer:

1. 50%

2. Every gamete only contains 50% of the genetic information or half of the information for a gene.

Explanation: 1. Heterozygous means the pairs consist of a dominant and a recessive, or one big and one small letter, so only 2/4 or 50% are heterozygous.

2. Every sex cell has half of the chromosomes you need to make an embryo so you end up only having one allele as well

A.Water dissolves salts and sugars.
B.Water will become less dense when frozen.
C.Water is transparent and lets sunlight pass through.

D.Water will from a spherical bead due to surface tension

Answers

I honestly don’t know ok leave me alone

Water is transparent and lets sunlight pass through. Therefore, the correct option is C.

Water's transparency and ability to pass through sunlight is not just a product of its polarity. This is mainly because water absorbs only specific wavelengths of light, particularly those in the visible spectrum, while allowing other wavelengths to pass through. Rather than being a direct result of polarity, this property is related to the electrical structure of water molecules and their interactions with light. On the other hand, the interplay of water polarity and hydrogen bonding is the reason for the A, B and D properties, respectively.

Therefore, the correct option is C.

Answers

Answer

alveoli

Explanation

During gas exchange oxygen moves from the lungs to the bloodstream. ... This happens in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.

Required Answer :-

The exchange of gases takes place in the alveoli.

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

Additional information :-

Alveoli are microscopic air sacs.

They are the primary sites of exchange of gases. Gas exchange also occurs in lungs and tissues by diffusion.

Atmospheric air contains little CO2, but blood flowing in pulmonary capillaries has a higher concentration of CO2.

CO2 diffuses from higher concentration in blood across walls of alveolar capillaries to lower concentration in air in alveoli.

Blood coming into pulmonary capillaries is oxygen poor and alveolar air is oxygen rich.

Oxygen diffuses from higher concentration in alveoli across walls of alveolar capillaries to lower concentration in blood.
