Answer:

  • <u>Option-(B):</u> The following is not an observation or inference on which natural selection is based is the characteristics of a poorly adapted individuals which can never produce offspring.

Explanation:

  • The idea of natural selection basically follows the analyses of the heritable characters which passes from one generation into another, having the specific set of data or genome been transferred into there descendants. And how each specie goes through the process of survival in order to have more chances to acquire the required natural resources and shelter for them selves inside a region or area.

1/4 recessive can be expected for the recessive trait of mono hybrids from the F2 generation.

Option D

<h3><u>Explanation:</u></h3>

Mono hybrid cross is defined as the crossing between two plants considering the two different alleles of a particular character. It was 1st performed by Father of Genetics, Sir Gregor Mendel. The mono hybrid cross done by him considered the character tallness of garden pea plants, of which one was tall and other was short.

He crossed them to get all tall plants in 1^{st} Filial generation. Now as he self bred those plants, he got the tall and short plants in ratio of 3:1. Thus he proved that the recessive trait of mono hybrids is 1/4^{th} of the total population of F2 generation.

Alla [95]

Answer:

ATP production.

Explanation:

The result will be the production of ATP molecules if we place thylakoids in a beaker with a solution that mimics the chloroplast stroma in direct sunlight. The thylakoids are able to formed ATP in the dark because H+ gradient is required for ATP synthesis. The scientists find out that the light reactions were not necessary to establish the H+ gradient required for ATP synthesis by ATP synthase.

"Explain how chemical energy for use in the cell is generated by electron transport and chemiosmosis"
Reika [66]

Answer:

Explanation:

The electron-carrier proteins are arranged in the inner mitochondrial wall. A dehydrogenase enzyme (think of it as the first protein of the electron-transport chain) oxidises NADH2 (which is the reduced coenzyme NAD) and/or FADH2 (reduced coenzyme FAD). The energy from the oxidation process is used to pump hydrogen ions from the matrix to the inter-membrane space of the mitochondrion. Because of this, gradient of hydrogen ion concentration builds up across the inner mitochondrial membrane, which generates a potential difference across the membrane. The protons then flow back to the matrix through an enzyme called ATP synthase (also called ATPase). (This is called chemiosmosis because a chemical substance (H+) moves across a membrane, down the concentration gradient.) This releases energy needed for the ATP synthase to phosphorylate ADP, i.e. make ATP (chemical energy for use in the cell) from ADP and inorganic phosphate.

Note: Bolded things are important, everything else is just additional clarification in case you need it. This is the last major phase of cellular respiration. If you want a deeper insight into the process, I suggest you read a bit about glycolysis and Krebs cycle.
