Answer:

c. number and variety of organisms vs. changing environment

Explanation:

In an ecosystem populations are in dynamic equilibrium with each other, for when a population decreases the population of its predators also decreases, because the various populations are dependent on each other for survival. What we can understand from this is that the diminishing population of a species has caused a change in the environment, making that environment unsuitable for the predator population.

In other words, dynamic equilibrium occurs when the size of a population of a species varies with changes in the environment in which they live. For this reason we can state that the number and variety of organisms vs. changing environment best indicates the dynamic balance of an ecosystem.

What is the colour change when universal indicator is added to apple juice

ipn [44]

Answer: The color would be light red

Explanation:

Apple juice is derived from apples which are rich in vitamin C. Chemically, vitamin C is an acid called ascorbic acid and apple juice also contain acids like folic acid and Pantothenic acid.

Hence, it is to be considered as acidic in nature.

So that, pH of apple juice is found to be in the range of 2.9 - 3.5.

Hence, the Colour of pH will be Light Red

Explanation:

D. E: photosynthesis; D: cellular respiration

Photosynthesis is a chemical pathway that’s integral to producing energy in plants and other primary producers. Energy in the form of molecules of glucose is produced from light, water and carbon dioxide while oxygen is released. This occurs in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent.

In the light reactions, occuring within the thykaloid, and stroma of the chloroplasts, water supplies the pigment chlorophyll with replacement electrons for the ones removed from photosystem II. Additionally, water (H2O) split by light during photolysis into H+ and OH- acts as a source of oxygen along with functioning as a reducing agent; it reduces the molecule NADP to NADPH by providing H+ ions. NADP and NADPH are integral to the dark reactions, or Calvin cycle where monosaccharides or sugars like glucose are produced after the modification of several molecules.

Respiration in the mitochondria utilizes oxygen for the production of ATP in the Krebs’s cycle via the oxidization of pyruvate (through the process of glycoysis). The electron transport chain, in which oxygen functions as the terminal electron acceptor, occurs in both plants and animals. Respiration includes:

Glycolysis: occurs in the cytoplasm 2 molecules of ATP are used to cleave glucose into 2 pyruvates, 4 ATP and 2 electron carrying NADH molecules.
The Kreb's cycle: in the mitochondrial matrix- 6 molecules of CO2 are produced by combining oxygen and the carbon within pyruvate, 2 ATP oxygen molecules, 8 NADH and 2 FADH2.
The electron transport chain, ETC: in the inner mitochondrial membrane, 34 ATP, electrons combine with H+ split from 10 NADH, 4 FADH2, renewing the number of electron acceptors and 3 oxygen; this forms 6 H2O, 10 NAD+, 4 FAD.
