1. What does aerobic refer to?
A. How your body uses oxygen
B. Limit the uses of oxygen
C. The absence of oxygen
D. With little available oxygen​

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.

A food chain in an ecosystem flows from green algae, to freshwater snails, to small fish, and finally to large fish.

Answers

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.

Answers

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.

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.

Vestigial structures: are various cells, tissues, and organs in a body which no longer serve a function. (Ex: human appendix, the pelvic bone of a snake, and the wings of flightless birds)

Homologous Structures: Homologous structures are organs or skeletal elements of animals and organisms that, by virtue of their similarity, suggest their connection to a common ancestor (Ex: humerus, radius, and ulna, just as the arms of the other animals included in the figure.

Embryological Similarities: The study of one type of evidence of evolution is called embryology, the study of embryos. (Ex: fish embryos and human embryos both have gill slits)

Fossil Record: history of life as documented by fossils, the remains or imprints of organisms from earlier geological periods preserved in sedimentary rock. (Ex: bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood, oil, coal, and DNA remnants)

Genetic (DNA) Similarities: a self-replicating material that is present in nearly all living organisms as the main constituent of chromosomes. It is the carrier of genetic information. (Ex:  basic materials in the chromosomes of the human cell.)

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.
