How many different ways does/could energy change form during its travels between the Sun and your stomach?

Answers

Answer 1

Answer:

Energy will take the path from sun to stomach as sun's energy to chemical energy followed by thermal and mechanical energy.

Explanation:

The energy of the sun is in the from of chemical energy which is the ultimate basis of life on earth . The process of photosynthesis occurs to form a chemical compound named glucose. The food ingested is in polymer complex forms as protein, carbohydrate, fats etc which is broken into monomers for absorption in intestine and stomach.

The dietary compound has energy stored in their bonds as chemical energy.

So, from sun human consume chemical energy which is stored in food.

The energy even if consumed by eating meat is also chemical energy which is stored as potential energy.

The breakdown of food or chemical energy into monomers leads to release of thermal energy or heat to maintain optimum body temperature.

Chemical energy also gets converted to mechanical energy which allows functioning of vital organs and movement of body.

7. How does the plant lichen quicken the weathering process? *(1 Punto)
They eat the rocks
They create new bacteria that breaks away rocks
They secrete acid that breaks away rocks
They eat the acid in rocks

Answers

Answer:

The correct answer is - They secrete acid that breaks away rocks

Explanation:

Lichen causes chemical weathering to break the rocks quickly which is the excretion of various acids like oxalic acid and many more organic acids that can cause a significant impact on the rock by dissolving minerals.

By breaking the rocks it forms the ground for the plant that will come later in place of the bare rocks by this chemical weathering process. An example of chemical weather is a change of the granite to clay with the help of hydrolysis.

Polydactyly is a rare autosomal dominant trait that is 80% penetrant. What is the chance that a child born to an affected father and a normal mother will have the disorder

Answers

The question is incomplete, below is the complete question.

Polydactyly is a rare autosomal dominant trait that is 80% penetrant. What is the chance that a child born to an affected father and a normal mother will have the disorder?

Assume the paternal grandfather is normal.

I will use P to encode polydactyl as it is dominant and use p allele to encode normal phenotype

P= Polydactyl

p= Normal

From what is given in the question,the paternal grandfather is normal and that means that the father of the child receives one wild type allele from the paternal grandfather, however,the father is affected with the disease,hence the genotype is A a but the mother being normal will have the genotype of aa.

That is Parents;

Father Aa × Mother aa

Gametes a a A Aa ( P ) Aa ( P )

a aa ( p ) aa ( p )

So if it is 100% penetrant, that implies that the chances of the affected child is;

(2/4 ) ×100=50%

However, only 80% penetrant is given here,so that is why the chances of the affected is then ; (50/100) ×(80/100) ×100= 40%

That means the affected child chances are 40%.

Final answer:

Polydactyly is a rare autosomal dominant trait with 80% penetrance.

Explanation:

Polydactyly is a rare autosomal dominant trait that is 80% penetrant. This means that if a person carries the genetic mutation for polydactyly, there is an 80% chance that they will express the trait. Therefore, if the father is affected by polydactyly (carries the gene) and the mother is normal (does not carry the gene), each child they have has a 50% chance of inheriting the gene from the father and a 50% chance of inheriting the normal gene from the mother.

However, if a child inherits the gene for polydactyly from the father, there is an 80% chance that they will express the trait, meaning they will have the disorder. On the other hand, if the child inherits the normal gene from the mother, they will not have the disorder.
