Answer:

Option A, Genotype

Explanation:

Genotype is the representation of allele pair acquired by an offspring after a cross is carried out between its parents (who too have a certain genotype)

When the two alleles of any particular trait in any individual are exactly similar to each other then the genotype of the individual is said to be homozygous while when these two alleles different from each other then the genotype of the individual is said to be heterozygous.

For example - if "T" and "t" are two alleles for height of an individual, then "TT" and "tt" represents the homozygous genotype while the "Tt" represents the heterozygous genotype

Hence, option A is correct

Oxygen gas is one of the products of photosynthesis.

Which reactant is the source for oxygen gas and how is it released?

A .

Water, released when sunlight splits it into oxygen and hydrogen ions

B .

Glucose, released when glucose is broken down into carbon dioxide gas, oxygen gas and water

C .

Carbon dioxide, released when sunlight splits it into carbon and oxygen gas

D .

Electrons, released when they strike the chloroplasts

Green plants capture energy and convert it into chemical energy by the process known as photosynthesis. During photosynthesis, carbon dioxide and water are transformed into simple carbohydrates and oxygen is liberated into the atmosphere.

light

6CO2 + 12H2O ----------------> C6H12O6 + 6O2

chlorophyll

Water is also used as a source of hydrogen required for reduction of carbon dioxide to form carbohydrate.

Water is oxidised in presence of light and chlorophyll. Hydrogen is removed from water and oxygen is released as follows:

light

4‎H20 ---------------> 2‎H20 + 4H+ + 4e− + O2

chlorophyll

or,

2‎H2O ----------------> 4H+ + 4e− + O2

Hence the source for oxygen gas is water and it is released when water splits in the presence of sunlight into oxygen and hydrogen ions.

So, the correct answer is 'Water, released when sunlight splits it into oxygen and hydrogen ions'.

This family of bacteria is often associated with urinary tract infections?

Colt1911 [192]

Answer:

The correct answer is C) Proteus

Explanation:

Proteus comes under the family Enterobacteriaceae and is often associated with urinary tract infections in animals and humans. These bacteria are often the part of intestine but become pathogenic when enter into urinary tract.

Proteus mirabilis is a gram negative anaerobic bacteria present as normal flora of intestine known to cause urinary tract infections in humans but most of the urinary tract infection is caused by E. coli.

When these bacteria get into the blood stream they can cause systemic inflammatory response syndrome and sepsis which has very high mortality rate.

Compared to its surroundings, the concentration of solutes is low inside a cell so, the cell is in a hypertonic, hypotonic or is

Kazeer [188]

Answer:

The cell is in a hypertonic solution.

Explanation:

The solution is hypertonic because the amount of solute(s) is higher outside of the cell than it is inside the cell, so the solvent (e.g. water) would move from the cell to the solution in order to obtain equilibrium between the two.
