What will the overall charge of an atom be if it has more protons than electrons?
sineoko [7]

Answer:

D

Explanation:

A: Neutrally charged atoms have the same number of protons and electrons.

B: Negatively charged atoms have more electrons than protons. These are also called anions.

C: ironically charged is a molecule that has a charge so a cation or an anion. This option isn't correct becuase it's not specific enough for the question. An ion can be positively charged (cation) or negatively charged (anion).

Under which conditions do most types of cells function at optimal levels
Scrat [10]

Explanation:

Cells maintain a constant internal environment; this process called homeostasis, ensures that cells obtain an optimal environment in which they can best function.

The endocrine system involves chemical signalling via the secretion of molecules called hormones into extracellular fluid. They bind to chemical receptors in order to cause specific changes in target cells, these lead to changes in the body's internal environment called homeostasis.

It includes the thyroid, parathyroid, pituitary, pineal and adrenal glands along with other regions. The bone, adipose tissue, heart, pancreas and liver are a few of the regions of the body which show endocrine function. The brain, or control center functions to receive and process the information from the receptor. Effectors receive the control center's command and illicits a response in the form of a feedback loop, that may oppose or enhance the stimulus.

Further Explanation:

During homeostasis the body maintains a constant internal balance in pH, temperature, blood pressure etc. Cells in a multicellular organism become specialized for particular tasks and communicate with one another in order to maintain homeostasis. Within the human body these are known as hormone cascades, where several complex steps occur- the tissues signal to one another with the use of hormones released by the endocrine system. The regulation (increase and decrease) of these secretions is achieved by negative feedback loops, where the release of certain substances during a cascade in turn halts the secretion of hormones at earlier stages.

For example, cells within the human body function at an optimal temperature between 97°F (36.1°C)  and 99°F (37.2°C). This is due to the optimal temperature requirement of the enzymes within the human body, which requires this specific range to obtain activation energy.

Which of the following best defines a gene pool?
DIA [1.3K]

Answer:

The correct answer would be a. the sum of all genetic traits in a population’s individuals at a given time.

A gene pool is defined as a sum total of all the genes present in an inter-breeding population at a specific time.

It includes all the alleles of all the loci within the genes of a interbreeding population or species.

The composition of the gene pool of a population can change with course of a time due to evolution.

A large and diverse gene pool enhances the ability of a population to adapt, survive and evolve in a nature.

What 4 things can affect the way enzymes work? Explain how each thing affects an enzyme
nadya68 [22]

Answer

temperature, ph, concentration and enzyme substrate

Explanation

Enzymes work best within specific temperature and pH ranges, and sub-optimal conditions can cause an enzyme to lose its ability to bind to a substrate. Changing the pH outside of this range will slow enzyme activity.

Enzymes will work best if there is plenty of substrate
