The appearance of fireflies at dusk is an example of a circadian rhythm because it a. is related to the phase of the moon
b. is related to the temperature of the air
c. happens daily
d. happens seasonally

Answers

It is a circadian rhythm because it happens daily. That is what circadian means as a term.

the right answer is C. happens daily

The circadian rhythm is studied by chronobiology. The circadian rhythm is the study of a 24-hour period during which a number of biological and physiological mechanisms are repeated. Circadian rhythms are modeled on an internal clock that regulates the rhythm of the waking / sleeping state, the rate of nail or hair growth, the rhythm of hormone production, blood pressure, the state of alertness, body temperature ... All living organisms have a circadian rhythm.

Which is a characteristic of all waves?All waves carry energy.
All waves move through space.
All waves move through matter, from particle to particle.
All waves transfer energy parallel to the direction of wave motion.

Answers

A) All waves carry energy

B and C cannot be correct, as some waves travel through space and some through matter, so this is not a characteristic of ALL waves. D cannot be correct either, as again not all waves move in the same ways. Hope this helps!

A property that is common to all waves is that all waves carry energy.

A wave is a disturbance along a medium which transmits energy. A wave is classified based on the direction of wave motion or based on the medium through which the wave is propagated. These two classifications of waves helps us to describe waves easily.

The properties of waves depends on whether the waves are mechanical or electromagnetic waves. However, a property that is common to all waves is that all waves carry energy.

Therefore, a common property to waves is that they all carry energy.

What is the function of the lung in a frog

Answers

A frog's lungs are involved in many functions, including breathing, vocalizing and hearing. Brown University explains that frogs use their lungs in the same way humans do to take in air. The breathing process is different, though, because a frog does not have ribs or a diaphragm like a human does, and these body parts help control air flow.

All of the statements below were part of the original cell theory proposed by Schleiden and Schwann with the EXCEPTION ofSelect one:

a. viruses are not living since they are smaller than a cell.

b. the cell is the most basic unit of life.

c. all living things are composed of one or more cells.

d. all cells come from other cells

Answers

The correct answer is option a. viruses are not living since they are smaller than a cell.

The cell theory does not propose the explanation for the viruses. As the viruses were discovered by Dmitry Ivanovsky in 1892, after the cell theory was proposed.

After advancement in microscopy, in year 1838 Schleiden and Schwann proposed cell theory.

The cell theory proposed by Schleiden and Schwann suggested that all the living organism are made up of cell. These cells are the smallest unit, which can perform all the function, which is required for a life, they can also divide, hence, it is the functional unit in all forms of life. They also said that a living organism at least have a cell or more than one cell.

Answer:

The correct answer would be an option a.

Cell theory was mainly formulated Matthias Schleiden and Theodor Schwann in 1839.

They postulated that:

All cells arise from pre-existing cells.

Each living organism consists of one or more types of cells.

The cell is a basic functional and structural unit of all living organisms.

Thus, option a. would be the correct answer.

Describe FOUR factors that may have an influence on the effectiveness of an antimicrobial treatment using various microbial control methods.

Answers

These are:
1. Number of microbes: if there is a lot of microbes, then more time is needed to kill all of them.
2. Characteristics of microbes: some microbes have resistance genes, so they will not react to agents they are resistant to; some microbes have protective structures so treatment will be inhibited.
3. Time of exposure: different agents will need different time to kill microbes.
4. Environment: the effect of temperature, pH, organics both on microbes and agents.
