Hormones exert an effect only on a gland or organ that has a ________ where that specific hormone can bind.

Answers

Hormones excite, inhibit, or regulate the activity of other organs when they exert their effect on a target cell where that specific hormone can bind.

A hormone is the substance secreted by certain glands that promotes, blocks or regulates the activity of the organs.

Target cells are cells that possess specific receptors for hormones on their surface.

The recognition of a hormone by its target cell lies in the presence at the cellular level of glycoproteins, called receptors, which bind specifically to the hormone, with high affinity and in a reversible way.

Receptors present some differences related to the type of hormone or neurotransmitter to which they bind, with their location in the cell and with the way of transferring information after their union with these molecules.

Therefore, we can conclude that hormones are produced by certain glands, circulate through the blood and reach other cells called target cells, exerting a regulatory effect on them.

Describe the process of oxidation in terms of electrons AND energy.

Answers

Oxidation is described as the loss of electrons and energy by a molecule.

OXIDATION:Oxidation is a process whereby a molecule loses electrons (e-) or energy to become positively charged.

Oxidation changes the oxidation number of the molecule involved depending on the number of electrons lost.

Reduction is the opposite of oxidation, and it entails gain of electrons and energy by a molecule. Together, they are called oxidation-reduction or redox reaction.

what is photosynthesis?​

Answers

Photosynthesis is the process by which plants generate simple carbohydrates. This process used the energy from the sun.

Photosynthetic reactions:Photosynthesis refers to the metabolic process by which plants and algae use the energy from the sun and carbon dioxide to generate simple carbohydrates and oxygen.

Photosynthetic reactions can be divided into light-dependent reactions and light-independent reactions.

The light-independent reactions (also called the Calvin cycle) generate simple carbohydrates such as glucose.

In conclusion, in photosynthetic reactions, plants turn carbon dioxide (CO2) and water (H2O) into simple carbohydrates by using the energy from the sun.

One parent may be dominantly having the mutation while the other parent may have the mutation but does not display its effects, thus labeling this parent as a carrier of the trait/mutation. Drawing a punnet square would best be used to describe the possibilities of each offspring and how each carries or shows the mutation inherited from their parents.
