What backs up a scientific law?

Answers

Answer 1

Answer:

Scientific laws are similar to mathematical postulates. They don't really need any complex external proofs; they are accepted at face value based upon the fact that they have always been observed to be true. Specifically, scientific laws must be simple, true, universal, and absolute.

What groups of organisms are most in danger of extinction?

A. Those with small population
B. Those that migrate or need special habitats
C. Those with large populations that breed quickly
D. Both a and b

Answers

Explanation:

D.Both a and B

As organisms with small population and those who migrate and need special habitat are most in danger of extinction.

The group of organisms that are in danger of extinction is those that have small populations and those that migrate or need special habits. So the correct option is D.

What is the extinction of species?

In biology, extinction refers to the extinction or death of a species. Extinction happens when a species' numbers are reduced due to evolutionary changes in its members, such as genetic inbreeding, poor reproduction, and population decline, or due to environmental factors like habitat fragmentation, climate change, natural disasters, and overexploitation of the species for human use.

The majority of species that have ever existed on Earth have gone extinct, but the fossil record indicates five very significant extinctions, known as mass extinction events, each of which resulted in the extinction of enormous numbers of species. The bulk of extinctions, which happen continuously and are described as background extinctions, are separated from these glaring decreases in the variety by the term "mass extinction."

Therefore, the correct option is D.

1. On average, 34-36 molecules of ATP are gained through the process of aerobic cellular respiration from
one glucose molecule.

2. When phosphate is added to ADP, free energy from food sources is stored in the phosphate bond,
producing ATP.

3. The hydrolysis of ATP to ADP is reversible.

4. When a phosphate group is removed from ATP by hydrolysis, ADP is produced and energy is stored for
cellular processes.

The evidence of evolution was posited by Charles Darwin. The theory of evolution states that all species are related and that they change over time

The different postulates of Drawin support the natural selection phenomenon. Darwin stated that the organisms that are fit and are able to change according to evolution are able to survive. This was known as the survival of the fittest.  

The evidence of the  evolution can be studied by fossil record , comparative embryology , molecular biology , and comparative anatomy.

Answer:

The primary consumer would is freshwater snails.

Explanation:

Producers are organisms that produce their own food and not depends on any other organism by the process of photosynthesis such as algae. Primary organisms on the other hand directly depend on the producers for their food and often get killed by secondary consumers.

Freshwater snails are the perfect example of the primary consumer as they get their food and energy from algae and are the primary source of food and energy for small fishes.

Which statement describes the electron sharing between two oxygen atoms?


Each oxygen shares one electron with the other.


Each oxygen shares two electrons with the other.


Each oxygen shares eight electrons with the other.


Each oxygen shares six electrons with the other.

Answers

When two oxygen atoms get close to each other, the attractions from the nucleus of both atoms attract the outer electrons.

What is Electrons?

A negatively charged subatomic particle known as an electron can either be free or attached to an atom (not bound).  The nucleus of an atom is made up of electrons, protons, and neutrons together.

The positive charge of a proton balances the negative charge of an electron. An atom is in a neutral condition when it has the same number of protons and electrons.

There are several ways in which electrons differ from the other particles. They are substantially less massive, exist outside of the nucleus, and show both wave- and particle-like properties.

Therefore, When two oxygen atoms get close to each other, the attractions from the nucleus of both atoms attract the outer electrons.

Answers

Answer:

Aspirin is administered in patients who produce blood hypercoagulation, that is why it is prescribed in order to antiaggregate platelets or platelet thrombi, this is how the platelets do not add or encompass each other and do not generate obstructions in the blood vessels to trigger an AMI (acute myocardial infarction) or CVA (cerebrovascular accident.)

Explanation:

Aspirin is an anticoagulant that is made up of N acetylsalicylic acid, that is, by an acid that inhibits the union of platelets with each other, that is why these in systemic situations where there is a tendency to hypercoagulation of the blood is a benefit for the patient .

Amit's infarction is caused by a platelet thrombus that obstructs the arterioles that supply the cardiac muscle tissue, that is, the coronary arteries. When these arteries are blocked by a platelet engulfment, the irrigation does not oxygenate the tissue and it suffers a transient hypoxia or anoxia that leads to partial necrosis and even in some cases of more serious situation it could be total where the person loses his life.

Answers

Answer:

A. How your body uses oxygen

Explanation:

Aerobic literally means "with oxygen", and refers to the use of oxygen in muscles' energy-generating process. Aerobic exercise includes any type of exercise, typically those performed at moderate levels of intensity for extended periods of time, that maintains an increased heart rate.

The correct answer to your question "What does aerobic refer to?" is: A. How your body uses oxygen.

Aerobic reaction can be defined as a biological and chemical reaction that occurs in the presence of oxygen.

On the other hand, an anaerobic reaction refers to a biological and chemical reaction that doesn't require oxygen such as glycolysis.

Some examples of an aerobic reaction include the following:

Krebs cycle.Electron transport chain.

In conclusion, aerobic refer to how the human body uses oxygen such as during physical exercises e.g running, walking, jogging, etc.
