1. How does the body adjust to a higher altitude?

1 answer:

8 0

During acclimatization over a few days to weeks, the body produces more red blood cells to counteract the lower oxygen saturation in blood in high altitudes. Full adaptation to high altitude is achieved when the increase of red blood cells reaches a plateau and stops.Heart rate is controlled by the two branches of the autonomic (involuntary) nervous system. The sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS). ... At the beginning of exercise, your body removes the parasympathetic stimulation, which enables the heart rate to gradually increase.

The syntenic genes A and Z are linked. A cross between two parents, AAZZ and aazz, produces F1 progeny with the AaZz genotype. W

garik1379 [7]

Answer:

The possible arrangements of alleles on the F1 progeny's chromosomes will be AZ/Az or aZ/az

Explanation:

The genotype of F1 progeny is AaZz

The allele pair of gametes would contain one allele for characteristic represented by "A or a" and other allele for characteristic represented by Z or z"

Thus, total four allele pairs will be formed.

First allele pair would be - AZ

Second allele pair would be - Az

Third allele pair would be - aZ

Fourth allele pair would be - az

Hence, the possible arrangements of alleles on the F1 progeny's chromosomes will be AZ/Az or aZ/az

Sodium Hydroxide + Copper Sulfate

AnnyKZ [126]

<h2>Answer:</h2>

Reaction for observation: Sodium Hydroxide + Copper Sulfate

Full reaction:

2NaOH + CuSO4 --> Cu(OH)2 + Na2SO4

Observations Before Interaction:

Sodium hydroxide is a turbid solution and copper sulfate is in form of bright blue crystals.

Observations After Interaction:

When their solutions are mixed with each other, a pale blue precipitate of basic copper hydroxide & a solution of neutral salt sodium sulphate will be formed.

Was Mass Conserved?

Yes, mass was conserved.

The Law of Conservation of Mass states that "mass cannot be created or destroyed, but changed into different forms".

Hence mass was conserved.

<h3>Part 4.</h3><h3>.Proof of a Chemical Reaction</h3>

The proof of the reaction is the appearance of pale blue precipitates of of basic copper hydroxide & a solution of neutral salt sodium sulphate.
