There are several differences between the two, but the biggest distinction between them is that eukaryotic cells have a distinct nucleus containing the cell's genetic material, while prokaryotic cells don't have a nucleus and have free-floating genetic material instead

Answer:

hopefully the diagram attached is helpful!

Explanation:

two main groups are ; bacteria and archaea

- they are single celled organisms that lack a nucleus

- bacteria cells walls contain peptidoglycan and archaea does not

Explanation:

Biotic factors include fungi,algae,bacteria etc.

While, Abiotic factors include soil, water ,sunlight and minerals

Answer:

[tex]\boxed {\tt D. \ Microorganisms}[/tex]

Explanation:

A biotic factor is a living thing in an ecosystem. For example: deer, rabbits, grass and trees are all biotic factors.

An abiotic factor is a nonliving thing in an ecosystem. Some examples include rocks, soil, and water.

Let's examine our answer choices.

Sunlight, nutrients, and precipitation are all nonliving, so they are abiotic factors. They can't be the correct choice.

That leaves: microorganisms. Microorganisms are very tiny organisms, like bacteria and amoebas. They are biotic factors, so the correct choice is D. microorganisms

What are possible products of glycolytic, or anaerobic, catabolism?

Answers

Answer:

The products of a glycolytic metabolism is lactic acid and the increase of the insulin enzyme at the plasma level.

Explanation:

Lactic acid is the product of the reaction of glucose catalysis in oxygen-deficient states such as in anaerobic activity.

Lactic acid is an acid that can be metabolized by the body, which accumulates in the muscles, and is generated once the physical activity has finished or in the last stages.

Insulin, once generating the rest of the activity, or the cessation of the action, comes into play at the plasma level and increases, in order to neoform new energy reserves (glucose) and thus prepare for the next action.

This hormone has the opposite effect to glucagon.

While you were on safari, your friend got bit on the leg by a posionous snake and nearly died from excessive hemolysis. Being a true scientist, you captured the snake and analyzed its venom to understand why it caused hemolysis. You found thwo enzymes, a protease (breaks down proteins), and a phospholipase. He isolated each of these enzymes and treated red blood cells with them. He found that only phospholipase caused red blood cell lysis. He also found that, after treatment of red blood cells with the phospolipase, there was excess amounts of free phosphophorylcholine (Choline phosphate group) and free diacylglycerol (glycerol with two hydrocarbon tails). 1.) What is the substrate for phospholipase and where does it cleave

Answers

Answer:

Phospholipase is an enzyme, which is classified into phospholipase A2 and phospholipase A1.

In this case we are talking about phospholipase A2, that is why the sn-2 ester bond of glycerophospholipids will be taken as a substrate, giving fatty acids as a product, such as arachidonic acid.

Explanation:

The glycerophospholipids used by this enzyme are those found in cell membranes, these pathways are usually associated with inflammation pathways for the formation of arachidonic acid that functions as an immunological mediator.

On the other hand, it must be remembered that membrane phospholipids are amphipathic, that is, with hydrophilic and hydrophobic molecules and are responsible for balancing the internal homeostasis of the intracellular environment.

See the options and the answer below

Explanation:

The available options to the question are:

Your statement is a valid scientific theory. Your statement uses the word "theory" in a non-scientific, colloquial way. Your statement is a hypothesis rather than a scientific theory. Your statement is not a theory but a fact.

The correct answer would be that:

the statement uses the word 'theory' in a non-scientific, colloquial way. the statement is a hypothesis rather than a scientific theory.

A hypothesis is a generalized statement with little or no experimental test. When a hypothesis is tested using a suitable experiment (s), it can either become valid or invalid. In order words, hypotheses are falsifiable. A theory on the other hand is a hypothesis that has been tested several times by independent researchers and found to be true.

In the illustration, the statement made concerning the squirrels is based purely on guess and not on fact. The use of the word 'theory' in the statement is totally unscientific. Only suitable experiments can prove or disprove the statement.

The correct options are 2 and 3.

Phenytoin (sodium channel blocker) and ethosuximide (calcium channel blocker) are anti-seizure drugs that stop seizures from happening. These drugs work by inhibiting electrical impulses (action potentials) from occurring. Explain the importance of sodium and calcium channels on a neuron and and the reasons why action potentials do not occur when these channels are inhibited

Answers

Answer:

Phenytoin and ethosuximide are drugs that slow the recovery of the sodium channel during the inactivated state.

That is to say, they prolong the inactivation state of the channel, thus generating that in this way the neuron remains in resting potential and the action potential causing the epileptic attack is not triggered.

On the other hand, these drugs, according to the bibliography of the book "Golan, 3rd Edition, Principles of Pharmacology" have a use-dependent affect capacity, this means that those sodium channels that have more activity will be more affected, in this way Not only is epileptic shock avoided, but if the same happens independently in any neuron, it will not be able to propagate the action potential to its neighboring neurons, therefore the surrounding neurons will not be stimulated and will not be fulfilled. with the sudden rapid discharges that are the most dangerous in some cases of severe epilepsy.

It is important to understand that these drugs affect the ion channels responsible for exciting neurons, that is why by inhibiting them, a constant rest of these neurons is promoted, and they are unable to generate abrupt discharges and dissemination of the electric charge. among them generating epileptic shocks.

The ions in neurons are in charge of indicating or modulating the different neuronal states, if they are inactive, open or closed, they will directly affect the membrane potential, that is, the positive or negative charge of the neuron's membrane.

Explanation:

In order to finish completing the question, these drugs are excreted through the p450 protein, that is why if this excretion system becomes saturated because another drug is consumed that is excreted in the same way, these antiepileptics will remain longer in use. blood and in the body, generating a greater effect and enhancing adverse effects on the central nervous system.

which of the following is most consistent with the modern theory of evolution​

Answers

The correct answer is Parents pass their physical traits to their offspring; those offspring with traits that help them survive in their environment are able to reproduce.

Explanation:

The modern theory of evolution explains the mechanisms that make organisms change. One of the main ideas this theory proposes is that organisms with traits that help them survive or reproduce have higher chances to pass their genes and traits to new generations. This mechanism makes certain traits to be favored and contributes to the evolution of organisms because after multiple generations certain traits will prevail while others will be eliminated.

Moreover, this theory specifies genes in an organism are not acquired or modified during its life but these are the results of the traits passed to the organism by its parents and evolution occurs only after a long time or multiple generations. According to this, the first option is the correct one.
