It is called as conservation biology. Conservation biology aims to protect species, their habitats and the ecosystem from extinction. It is one field of ecology that focuses on the environmental problems caused by humans. It aims to reverse and understand the cause of loss of biodiversity.

how could incoming radiant energy from the sun be affected as a result of changes in albedo in the Arctic region?
lapo4ka [179]
As albedo in the Arctic region is getting higher, incoming radiant energy of the sun will be more reflected. If albedo in the Arctic region is falling, incomig radiant of the sun will be more absorbed.
Albedo is a name of overall reflectivity in terms of the Sun's spectrum.

Some microbiologists recommend reincubating organisms producing methyl red negative results for an additional 2-3 days. why do y
Tpy6a [65]
The organism should be  re-incubating to permit it to have additional opportunity to create finished results that might be acidic. It may be the case that there isn't sufficient finished result to change the shade of the Methyl Red yet.Some microbiologists prescribe re-brooding life forms delivering methyl red-negative outcomes for an extra 2 to 3 days to build test sensitivity.

The ability of a hormone to affect the activities of a particular cell depends on that cell having specific receptors with which
anzhelika [568]

Answer:

The correct answer is c) The first statement is true; the second is false.

Explanation:

To be able to perform its role, a hormone must bind a specific receptor in its target cell. The receptor can be located inside the cell (in cytosol) or in the surface of the cell (transmembrane receptor). By regulating the expression of the receptor, the target cell regulates the hormonal activity.

The number of hormone receptors in a cell is not constant, it can vary depending on sereral factors, such as the age of the organisms, the effect of several drugs, mutations or diseases.

"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.
