Answers

Answer:

The most suitable answer is C.

Explanation:

Photosynthesis is the process whereby plants manufacture their own food using water, carbon (iv) oxide and some other minerals in the presence of sunlight while cellular respiration is the oxidation (or breakdown) of substances in the mitochondria (site of cellular respiration) in living cells.

What are 2 similarities and 2 differences between photosynthesis and cellular respiration?

Answers

Answer:

Photosynthesis and respiration are biological reactions that complement each other in the environment. Both photosynthesis and cellular respiration cannot occur without the other. However, there are differences between photosynthesis vs. cellular respiration. Photosynthesis involves the use of energy from sunlight, water, and carbon dioxide to produce glucose and oxygen, whereas cellular respiration uses glucose and oxygen to produce carbon dioxide and water.

Respiration and photosynthesis are biological reactions in the environment that complement each other. Both are similar reactions that occur in a specific manner. In the process of respiration, oxygen and glucose yield water and carbon dioxide, while carbon dioxide and water yield glucose and oxygen during the process of photosynthesis.

Explanation:

Cellular Respiration

Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules or nutrients into adenosine triphosphate (ATP), and then release waste products. The reactions involved in respiration are catabolic reactions, which break large molecules into smaller ones, releasing energy because weak high-energy bonds, in particular in molecular oxygen, are replaced by stronger bonds in the products. Respiration is one of the key ways a cell releases chemical energy to fuel cellular activity. The overall reaction occurs in a series of biochemical steps, some of which are redox reactions. Although cellular respiration is technically a combustion reaction, it clearly does not resemble one when it occurs in a living cell because of the slow, controlled release of energy from the series of reactions.

Answers

Answer: Concentrated in certain areas

Explanation:

Volcanoes are usually formed as a result of collisions or other activity between plates at plate boundaries.

As a result, they are more usually concentrated in zones where there is more plate activity such as at the edges of continents, on islands and beneath the seas in certain areas because this is where plates usually collide with each other.

Complete question:

In garden peas, yellow seeds (Y) are dominant to green seeds (y), and inflated pods (I) are dominant to constricted pods (i).

Suppose you have crossed YYII parents with yyii parents.

Draw the F1 Punnett square and predict the expected F1 phenotype(s). List the genotype(s) of gametes produced by F1 individuals. Draw the F2 Punnett square. Based on this Punnett square, predict the expected phenotype(s) in the F2 generation and the expected frequency of each phenotype.  

Answer:

F1 phenotype ⇒ 100% plants heterozygous for both traits, expressing yellow seeds and inflated pods, YyIi. F1 gametes ⇒ YI, Yi, yI, yiF2 Phenotype ⇒ 9/16 are expected to be plants with yellow seeds and inflated pods,    Y-I-3/16 are expected to be plants with yellow seeds and constricted pods, Y-ii3/16 are expected to be plants with green seeds and inflated pods, yyI-1/16 are expected to be plants with green seeds and constricted pods, yyii

Here we've got a condition, in which an inexperienced pea has traits that include the colour of the seed, and the nature of the pod, wherein the Yellow colour seed (Y) is dominant over the inexperienced colour seed (y), and the inflate pods (I) is dominant over the constricted pods (i).

When we make a pass among true-breeding mother and father having yellow colour seed, and inflated pods with true-breeding determine have inexperienced colour seed and constricted pods, then withinside the F1 technology we get -

The genotype of a true-breeding determines having a yellow colour seed, and inflated pOds=YY||.The genotype of a true-breeding determined to have inexperienced colour seed and constricted pods = yyii.A pass among YYII (Yellow, inflated) x yyii (Green, constricted).Gametes are made out of a mother and father having genotype YY|I=YI.Gametes are made out of a mother and father having genotype i = Yi.
