Look at the reaction below.
Ray Of Light [21]

Answer:

Ca(OH)2 (aq)

Explanation:

The balanced neutralization reaction i.e. a reaction between an acid and a base, in this question is given as follows:

H2SO4(aq) + Ca(OH)2(aq) → CaSO4(aq) + 2H2O(l)

According to Arrhenius in his definition of acid and base, a base is a substance that dissociates into hydroxide ions (OH-) when in an aqueous solution. In other words, a base increases the concentration of hydroxide ions when dissolved.

In this reaction, Ca(OH)2 releases the OH- (hydroxide ion) that combines with the hydrogen ion (H+) released by the acid, H2SO4, to form water (H2O). Hence, Ca(OH)2 (aq) is the BASE.

What specific key factor starts the breathing process in a newborn infant?
kvv77 [185]
Chemical factors: This is due to internal stimuli. Changes in the blood such as decrease in O2, increase in CO2 and decrease in PH cause impulse in the carotid artery which stimulates the respiratory centers in the medulla and cause breathing.

Mechanical factors: also called external stimuli. Compression of the fetal chest during delivery forces small amount of lung fluid out of the lungs. This increase in pressure in the chest draws air into the lungs.

A cat with LONG HAIR (heterozygous) is a carrier of the short hair allele. Its mate has SHORT HAIR. Use a Punnett Square to dete
Helen [10]

Answer:

50%

Explanation:

Hi there!

We are given the hair types of two cats

The first one has long hair, and it's heterozygous, meaning it has one dominant, and one recessive allele. We are given that it is a carrier of the short hair allele, meaning in its genotype, it has the short hair gene (that doesn't necessarily mean it's there in its phenotype). However, since it has long hair (genotype), that means that the long hair allele is dominant (the gene that will always show), and the short haired one is recessive (the gene that gets "covered up" by the dominant allele). Let's say the genotype of the long haired cat is Tt, where T is the long hair, and t is the short hair  

The second cat has short hair, and as we have mentioned above, the allele for short hair is recessive, so the short haired cat has 2 copies of the short hair allele. Its genotype is tt

Please see below for the Punnett Square

Hope this helps! :)
