Answer:

3 (Cells carry out the respiration process)

Explanation:

Cellular respiration is a metabolic (catabolic) process common to all living things as all living things need energy for their life processes.

Respiration is the biochemical process in which the cells of an organism obtain energy by breaking down organic molecules in presence or absence of oxygen (aerobic or anaerobic) resulting in the release of Carbondioxide (CO2), water and Adenosine triphosphate (ATP).

Food molecules (containing stored energy in their chemical bonds) absorbed after digestion are broken down and the energy within their molecules are freed. This freed energy in form of ATP, is used to power the organism's movement and physiological functions.

Note that, ATP is an energy carrying molecule and a usable form of energy by cells. This is so because ATP releases energy quickly. Energy is released from ATP when the end phosphate (Pi) is removed to become ADP (adenosine diphosphate), which is a low energy molecule.

Aerobic cellular respiration consists of Glycolysis, Kreb's cycle and Oxidative phosphorylation. A total of 38 ATP molecules is produced in the cytosol of prokaryotes while a total of 36 ATP molecules is produced in the mitochondria of eukaryotic cells.

What does the phase of the moon seen from Earth depend on?

Degger [83]

We see the moon because the sun's light reflects off it. So the phases change depending on how much the sun reflects of it. The moon circles around the Earth so at certain times there will be a full moon and at certain times a new moon and everything in between.

A student is setting up a model to study the carbon cycle and natural sources of carbon dioxide. They create a microenvironment

Alex Ar [27]

The natural source of carbon dioxide that was left out is the calcareous shells of organisms. The major metabolic process that was left out is respiration.

<h3>What is carbon dioxide?</h3>

Carbon dioxide is one of the gases that cycle around in the universe. It is an integral part of the carbon cycle. The carbon cycle is a model that depicts the movement of carbon in the ecosystem.

The natural source of carbon dioxide that was left out is the calcareous shells of organisms. The major metabolic process that was left out is respiration.

How can you test the idea that solar energy is required for the reduction of NADP+ to NADPH?

AysviL [449]

Answer:

In addition to biology, evidence drawn from many different disciplines, including chemistry, geology, and mathematics, supports models of the origin of life on Earth. In order to determine when the first forms of life likely formed, the rate of radioactive decay can be used to determine the age of the oldest rocks (see optional problems C and D, below) exposed on Earth’s surface. These are found to be approximately 3.5 billion years old. The age of rocks can be correlated to fossils of the earliest forms of life. A. The graph compares times of divergence from the last common ancestor based on the fossil record with a "molecular time" constructed by comparing sequences of conserved proteins to determine a mutation rate (after Hedges and Kumar, Trends in Genetics, 2003). Explain how such a molecular clock could be refined to infer time or the evolution of prokaryotes. B. Using a molecular clock constructed from 32 conserved proteins, Hedges and colleagues (Battistuzzi et al., BMC Evol. Biol. 2004) estimated the times during which key biological processes evolved. A diagram based on their work is shown. Connect the time of the origin of life inferred from this diagram with the age of the oldest fossil stromatolites and the age of the oldest exposed rock to show how evidence from different scientific disciplines provides support for the concept of evolution. Evaluate the legitimacy of claims drawn from these different disciplines (biology, geology, and mathematics) regarding the origin of life on Earth. The oldest known rocks are exposed at three locations: Greenland, Australia, and Swaziland. The following application of mathematical methods provides essential evidence of the minimum age of Earth.
