Answer:

a pair of factors known as genes control traits, one gene comes from each parent for every tree, each trait is passed from generation to generation, when game it's are found genes separate, if there are two unalike jeans one maybe seen while the other is hidden.

Answer:

• A pair of factors (known as genes) control traits.

• One gene comes from each parent for every trait.

• Each trait is passed from generation to generation.

• When gametes are formed, genes separate.

• If there are two unlike genes, one may be seen while the other is hidden.

Explanation:

The things that Mendel would include in his hypothesis will be genes. This is an hereditary unit that is being passed to.a child from their parents. This gene comes from each parent for every trait and is passed down across different generations. These traits passed down to the child can be height, shape, color of the seed etc.

It should be noted that when the reproductive cells are being formed, the genes will be grouped differently and in situations whereby the gender are not thesame, one will be a dominant gene while the other will be a recessive gene.

Describe the role of the following in synaptic communication:______.
Scilla [17]

Answer:

1- Ionotropic receptors form ionic channels that allow certain ions to pass through the plasma membrane, and metabotropic receptors, which are associated with G proteins and have a modulating action on synaptic transmission.

2-Neurons communicate with each other through neurotransmitters, which are the molecules responsible for sending signals from one neuron to the next neuron. Neuromodulators also enter into communication between nerve cells.

3-Rapid PPSE occurs when postsynaptic nicotinic receptors on dendrites and neuronal cell bodies are activated through acetylcholine, which causes membrane depolarization and allows the entry of Na and Ca ions.

Acetylcholine also allows the activation of postsynaptic muscarinic receptors, which leads to the slow excitatory postsynaptic potential. This occurs when the channels are Ca and Na open and the K channels are closed.

4-When the neurotransmitters are attached to their receptors, the opening of the ion channels can be opened. This leads to two types of postsynaptic potentials being generated: postsynaptic excitation potentials (PEPs), if the membrane potential is depolarized, and the postsynaptic potential inhibitors (PIPs), if the membrane potential is hyperpolarized.

Explanation:

1-The importance of studying neurotransmitter receptors is that most of the drugs of clinical importance, such as anesthetics, anticonvulsants, etc., are based on the mechanisms of action of these receptors

2-Neurotransmitters allow them to produce or not action potential, serves to activate postsynaptic receptors and are capable of opening ion channels. On the other hand, neuromodulators are responsible for regulating the activity of ion channels.

3-The fast PPSE reaches 15 milliseconds. The slow PPSE lasts approximately 1-2 minutes.

4-PEPs occur when the ionic channels of Na + or Ca2 + are opened, while PIPs when the channels  of K + or CI- are opened.

What is the error in this experiment please ??
True [87]
An error is that the scientist did not control their variables. They had one group of people playing the game at 6, and another group playing at 12. This means that other things might have affected the scores other than what was being tested, which was caffeine.

Which of the following statements BEST describe viruses? Pick ONE.
Sidana [21]

Answer:

They can not live on their own

Explanation:

The main difference between cells and viruses is that viruses need another cell to infect so that they can reproduce. Cells on the other hand can reproduce on their own.

What would have happened if Avery had added an enzyme that digests it all the nucleus acids in the mixture of heat-killed bacter
telo118 [61]
The answer is most likely B). 'The harmless bacteria would not have been transformed, and the mice would have lived,' because, then bacterium transform, they use the genetic material present in their environment to do so, and when Avery destroyed the nucleotide bases(Genetic material) with an enzyme he destroyed any chances that the bacteria would have had at transforming into the virulent strain.
