An experiment was conducted to demonstrate the passage of glucose and starch across a selectively permeable membrane that allows monomers but not polymers to diffuse through.

Glucose and starch powders were mixed in 10 ml of water and poured into a cellulose bag, which was then sealed at both ends and placed in a beaker of water. After 30 minutes, the presence of glucose in the beaker was recorded with a testing paper, which turns green if glucose is present. The presence of starch was recorded by adding a few drops of iodine, which causes the solution to turn violet if starch is present.

A beaker filled with 100 milliliters of distilled water. A bag filled with 10 milliliters of water and a solution of 2 percent glucose and 2 percent starch is placed in the beaker of water.

Which statement best describes the expected result?

A) The testing paper will turn green and the solution will turn violet.
B) The testing paper will turn green and the solution will not turn violet.
C) The testing paper will not turn green and the solution will turn violet.
D) The testing paper will not turn green and the solution will not turn violet.

Answer:

According to the pedigree, It is clear that the F1 generation is not affected but their offspring are affected in F2, which explains that the deafness presented with the pedigree is recessive. It should be an Autosomal recessive inheritance as it is found in both male and female offsprings.

As it is found that the parents are affected in 5th gen and 6th generation but their offspring are not affected which means there must be more than one genes controlled this disorder

B. In 5th generations mentioned above offspring is unaffected but parents are affected, to find the genotype of the individual let assume there are two genes responsible for it A and B, and mutation in any one of them can result in deafness.

So in IV generation Individuals 5 and 6 have genotypeAAbb and aaBB; both are deaf.

gametes:- Ab & aB.

So, the genotype of all offsprings will be AaBb means all are normal.

Deafness is an autosomal recessive disorder as the first generation is unaffected and the genotype of the fifth generation is AaBb.

Pedigree is a chart representation of the phenotype of specific genes of the organism and its inheritance from the ancestral family. The pedigree can be used for the analysis of the heritable disease and illness in the family root.

The deafness illness in the pedigree is recessive as the first generation of the pedigree remains unaffected but the later generation is affected and is diseased.

From the chart, deafness can be said to be an autosomal recessive disorder as some generations are unaffected and in some the disease is present. More than one gene is controlling the disease as the fifth and sixth generations are affected but not their offspring.

The parent of the fifth generation are affected but their progenies are normal to know the genotype let's assume the genes A and B to be responsible for the disease and the mutation in any one of the alleles will result in deafness.

Hence, the genotype of the parents 5 and 6 in the fourth generation will be AAbb and aaBB as both of them diseased or deaf, the offsprings produced from their cross will be AaBb that is all the offspring of the fifth generation will be normal and unaffected.

Therefore, the genotype of the fifth generation in the pedigree is AaBb.

Explanation:

It will compare that neither has an affect on the population and it will also compare that both will be equal to one another.

The term "population" refers to all citizens who are either permanently residing in a country or who are just passing through. This indicator reveals how many people typically reside in a certain area.

Growth rates are the population changes that occur each year as a result of births, deaths, and net migration.

The total population also includes national military forces deployed overseas, merchant mariners at sea, diplomatic staff based abroad, civilian foreign nationals residing in the nation, and internally displaced people residing in the nation. Demographic tools like population predictions are frequently used.

Therefore, It will compare that neither has an affect on the population and it will also compare that both will be equal to one another.

Chloroplast is not a site of lipid synthesis, it is the site of performing photosynthesis Therefore, option A is correct.

An organelle found in the cells of plants and some algae called a chloroplast is where photosynthesis, the process by which solar energy is transformed into chemical energy for growth, takes place.

All green tissues in plants and algae contain chloroplasts in their cells. In photosynthetic tissues that don't appear green, such as the brown blades of gigantic kelp or the red leaves of some plants, chloroplasts are also present.

Thus, the cell wall provides support and protection to the cell, rough ER is the site of protein synthesis, the nucleus holds genetic material, and the chloroplast is the site of photosynthesis. Therefore, option A is correct.

Answer: The process of photosynthesis is energy-conserving because no energy is used throughout the process of forming glucose and oxygen molecules.

Explanation: Plants create glucose through sunlight for food, which conserves energy

Answer:

Stomata

Explanation:

Photosynthesis is a unique phenomenon in certain organisms like plants. It is the process whereby they produce their food, in form of an organic compound called GLUCOSE. To synthesize this sugar, plants need a carbon source.

Plants utilize carbon dioxide (CO2), which is an inorganic carbon compound as CARBON SOURCE to synthesize glucose molecule in the process of photosynthesis. This carbon dioxide (carbon) is taken in by the plants via their STOMATA, which is a pore or opening present on their leaves.

The STOMATA opens and closes in order for gaseous exchange to occur i.e. take in CO2 (carbon dioxide), expel O2 (oxygen).

The statement that explains the importance of carbon in our cells is that carbon affects the function of the cell. So the correct option is A.

The most common chemical element present on our Earth is carbon. It has the symbol C and an atomic number of 6. The carbon atom is a member of the fourteenth group present on the periodic table.

The word carbon is derived from the Latin word 'carbo', which means coal. Carbon is also the 15th most abundant element that is present in the crust of the Earth. On the earth, carbon is the fourth most abundant element ranked after hydrogen, helium, and oxygen.

Carbon atoms, when bonded together in different ways,  are called as allotropes of carbon. Diamond, graphite, and amorphous carbon are the three allotropes of carbon.

They have different properties. Graphite is one of the softest known substances while diamond is the hardest known substance.

Therefore the correct option is A.
