<u>Answer 1</u>- Earthworms are decomposers. They decompose the organic matter and convert the complex substances into simpler digested molecules. These molecules are released into the soil by the feces of earthworms. This way earthworms replenish the soil fertility and return the nutrients back to the ecosystem.

<u>Answer 2</u>- Food chain is a series in which organisms are placed in a systematic order of flow of energy and nutrients. An example of food chain with earthworm is shown in image shared below.

Dinitrophenol increases the permeability of the lipid bilayer of the inner mitochondrial membrane to protons. Assuming that all
Zigmanuir [339]

Answer:

The correct answer is : C .It will decrease ATP production because fewer protons will be able flow down through ATP synthase.

Explanation:

  • Oxidative Phosphorylation is a process which involves two steps:  
  1. Transport of electrons from the reduced compounds like NADH (Nicotinamide adenine dinucleotide hydrogen) and FADH₂ (Flavin adenine dinucleotide dihydrogen) through the electron transport complexes, located in the inner mitochondrial membrane, to oxygen for the generation of water molecules.
  2. Synthesis of ATP or adenosine triphosphate from ADP or adenosine diphosphate and inorganic phosphate by an enzyme called ATP synthase which is located in the inner mitochondrial membrane. This enzyme harnesses energy by carrying protons from the inter-membrane space into the mitochondrial matrix and in the process produces ATP.
  • Oxidative phosphorylation takes place in the mitochondria, especially involving the inter membrane space, inner membrane and mitochondrial matrix
  • During the transport of electrons through the protein complexes (I, II, III, IV) of the electron transport chain a proton gradient is generated across the inner mitochondrial membrane.
  • The proton gradient is such that the concentration of protons is more in the inter-membrane space and less in the matrix of the mitochondria.
  • This proton gradient provides the energy to the ATP synthase for the synthesis of ATP.
  • Dinitrophenol is responsible for making the inner mitochondrial membrane permeable to protons. As a result protons can directly diffuse through the inner mitochondrial membrane from the inter-membrane space into the mitochondrial matrix equalising the concentration of protons across the inner mitochondrial membrane. This causes distortion in the proton gradient.  Hence, protons are no longer available for the ATP synthase to operate and synthesise ATP.

Is the correct order in a homeostatic feedback system stimulus, receoptor, control centre, effector?
Fantom [35]

Answer:

Correct

Explanation:

Homeostatic is nothing but ability of a system or living organism to manipulate its internal environment to maintain a stable equilibrium, for example the ability of warm-blooded animals to ascertain a constant body temperature.

The Homoeostatic feedback mechanism has three basis components and they are independent to one another.

These components are receptor, effector and integrating center. The function of receptor is to sense external stimuli and send information to integrating center. The integrating center generally hypothalmus in brain sends this signal to effector for example an organ to react to the stimuli.

So, the order  in a homeostatic feedback system stimulus, receoptor, control centre, effector is correct.

What happens during the four stages of mitosis
riadik2000 [5.3K]

Phosphate is when DNA has already been replicated. Metaphase is when the spindle attaches to the chromosomes. Anaphase is when the cells split and are called daughter cells. Telophase is when the nuclei is formed.
