What are the starting materials and products of photosynthesis and cellular respiration?

1 answer:

5 0

Photosynthesis usually happens in the leaves of the plants.This process undergoes a
complex process and involves two stages.The light dependent stage uses water as its
raw material and has its product which is oxygen and NADPH. Carbon dioxide is the material used for the second stage - the light independent stage. During this stage, glucose has been created.

Photosynthesis is the process to store energy and cellular respiration releases the energy stored. Glucose and Oxygen are the materials used in cellular respiration and releases water and carbon dioxide.Cellular Respiration goes through the processes Glycolysis,Transition Reaction, the Krebs Cycle and the Electron Transport Chain and Chemiosmosis, respectively.

Norma-Jean [14]

Answer:

Up-regulation.

Explanation:

Hormones may be defined as the chemical messengers of the body that can transmit information and maintains homeostasis. The hormones can directly go into the bloodstream and may release through the special ducts.

The receptors of the hormone is required for the binding of the receptors. To maintain the normal homeostasis of the body, the body shows the up regulation and down regulation. In up regulation the hormone levels increases in the body by increasing the receptor on the specific target organ.

Thus, the correct answer is up regulation.

People with diseases that result in the malabsorption of which nutrient are at risk for a vitamin d deficiency?

grigory [225]

Inadequate dietary vitamin D or its deficiency leads to malabsorption of calcium. Nutritional disorder leads to the rare disease rickets, which causes bones to become soft and bend in children. In adults, vitamin D deficiency leads to osteomalacia, which causes weak bones, bone pain and muscle weakness.

The body needs vitamin D to properly absorb calcium and phosphorus from the diet. However, keeping the right quantities of calcium and phosphorus in bones is challenging when vitamin D levels are low.

The two sources of vitamin D are-

Natural sunlight
Foods such as fish oil, Egg yolk and fatty fishes like salmon and mackerel

There are other disease conditions which lead to poor absorption of vitamin D-

Inflammatory bowel disease
Celiac diseases
Kidney problems

slega [8]

Answer:

Option D, only II, III, and IV

Explanation:

Complete Question

Ecosystem services include processes that increase the quality of the abiotic environment. Which of the following processes would fall under this category?

I) Keystone predators have a marked effect on species diversity.

II) Green plants produce the oxygen we breathe.

III) The presence of land plants builds soil.

IV) The presence of diverse wetlands helps in flood control.

A) only II and IV

B) only I and III

C) only I, II, and IV

D) only II, III, and IV

Solution -

The services of ecosystem has been classified into four groups

a) Provisioning – Where essential abiotic and biotic substance are produces such as production of food and water, reproducing offspring etc.

b) Regulating – the ecosystems is controlled through environmental factors such as control of climate and disease

c) Supporting – Ecosystem support the activities that are essential for survival. Primarily includes all nutrient cycles, oxygen generation etc.

d) Cultural – Provide aesthetic view and recreational benefits

Option II co mes under supporting service of ecosystem

Option III co mes under Provisioning service of ecosystem

Option IV co mes under Regulating service of ecosystem

Hence, option D is correct
