He found that the bacteria in the green light changed in color from green to red after multiple weeks of exposure but were still reproducing at the same rate. What can you conclude about the change in pigmentation of the cyanobacteria exposed to green light?

1.) More chlorophyll a was produced in response to the green light exposure

2.) The cyanobacteria were dying and were changing color in response

3.) Red light instead of green light was being absorbed by the chloroplasts

4.) More red photosynthesis pigments were produced to absorb green light

Answers

Answer:

#4.. More red photosynthesis pigments were produced to absorb green light

Chlorophyll, carotenoids, and phycobiliproteins, as well as additional classes like scytonemin, which are more focused on cyanobacterial cells' protection, are the three main classes of photosynthetic pigments that stand out in cyanobacteria. Thus, option D is correct.

What are the characteristics of cyanobacteria?

Many plants depend on cyanobacteria for their wellbeing and development.

Being able to transform inert atmospheric nitrogen into an organic form, like nitrate or ammonia, makes them one of the very few types of organisms that can do so.

Cyanobacteria are microscopic, photosynthetic organisms that are classified as bacteria.

They were once known as blue-green algae. Since dense growths frequently color water green, blue-green, or brownish-green, they were previously referred to as blue-green algae.

Therefore, More red photosynthesis pigments were produced to absorb green light.

C. True in all elements, it maintains its properties even after it combines with

other elements.

D. True to all elements, they have the properties after they are combined.

The correct option is D.

True to all elements, they have the properties after they are combined.

Explanation:

Elements are pure substances which can not be divide by any form of chemical means.

True to all elements, they have the properties after they are ccombine because elements contain atoms and atoms is the smallest indivisible units which retain chemical properties because chemical bonds are formed between the atoms of elements.

an increase in the concentration of protons in the cytosol will most likely have which of the following effects on glycolysis

Answers

Answer:

Reaction rate will increase as a result of the increased H+ concentrate

Explanation:

Because the more ions the faster the reaction rate

The increase in the concentration of protons ; increases the Reaction rate

An increase in the number the positive ions ( H⁺ ) in a reaction will lead to an increase the reaction rate and a decrease in the activation energy.

Therefore as the number of protons ( H⁺ ) in the cytosol increases, the ripple effect it will have on glycolysis will be an increase in the rate of reaction ( i.e. Reaction rate ) and a decrease in activation energy.

Hence we can conclude that an increase in the concentration of protons in cytosol will increase the Reaction rate of glycolysis.

Why did some people think that there was evidence of intelligent life on Mars?

Answers

Answer:

Recent missions to Mars haven't turned up definite proof of life, but some tantalizing possibilities have been uncovered.

Explanation: Water and ice caps if there's water there's life. but its not entirely true... because there isn't any life on mars... or so NASA says National Aeronautics and Space Administration more like Never a straight answer.

Many people believed that there was evidence of intelligent life on Mars, because of the similarities of this planet to planet Earth and because there are indications that there was water on Mars.

Although it is currently known that there is no intelligent life on Mars, many researchers believe that this planet has been inhabited in the past.

There is some evidence that allows this speculation to be established. Among this evidence, scientists claim that:

Mars has some characteristics similar to planet Earth.Many rocks on Mars have organic molecules.There is evidence that the surface of Mars once had water about two thousand years ago.There is water at the poles of Mars.There are water flows on the planet's hot slopes that are resistant to freezing.

With this, we can see that, according to the evidence, it is not possible to affirm that there was already intelligent life on Mars, but that the planet has the possibility of having been populated by microorganisms.

Yes, amylase can be reused, and when fulfills its catalytic function, it is free to catalyze the breakdown of another starch molecule.

Explanation:

Amylase is an enzyme capable of catalyzing the breakdown of starch bonds, separating it into glucose molecules.

The enzymes, including amylase, have the property of being free and without structural alteration when catalyzing a reaction, to bind to the specific substrate and catalyze a new reaction.

Amylase is not consumed, unlike a reagent, so it can be reused in new reactions.

What is the difference between facilitated diffusion and active transport?

Facilitated diffusion uses ATP and moves substances with the concentration gradient; active transport does not.

Active transport uses ATP and moves substances against the concentration gradient; facilitated diffusion does not.

Active transport uses ATP and does not require a carrier protein; facilitated diffusion does neither.

Facilitated diffusion uses ATP and requires a carrier protein; active transport does not.

Answers

Answer:

Active transport uses ATP and moves substances against the concentration gradient; facilitated diffusion does not.

Explanation:

Active transports moves against the concentration gradient (hence why it needs energy or ATP to do so, its going "against the grain"). Facilitated diffusion does not require ATP but does something require carrier proteins during passive transport.

base on what you have learned from the previous activities, define speech context in your own words.
plsss help

Answers

Answer:

This refers to the condition, environment and or circumstance under which a speech or communication was made.

Explanation:

The context of a speech can significantly alter their meaning even though the body of the information has not changed. This is why understanding contexts are very crucial.

The context of a speech helps the receiver to make a decision about what to place importance on and about what, he or she can safely make assumptions about.

Some examples of communication contexts are:

Mass communicationIntrapersonal communicationInterpersonal communicationGroup communicationPublic communication

Cheers

Speech context has to do with the circumstances that are available which affects the meaning of a speech.

There are three types of speech context which include:

Intrapersonal InterpersonalPublic

As a result of this, when a person is making a speech to either himself, one more person, or to a group of people, it is important to note that the audience is very important so that the message will be well received.

Interpersonal communication has to do with the communication between people you have a close relationship with.

Intrapersonal communication is the type of communication where a person talks to himself, usually loudly.

Public communication is the communication among a group of people.

Mia conducted a five hour experiment. She used a liquid solution. The solution decreased by 9/8 ounces every hour for 5 hours. At the end of the experiment, there were 99/8 ounces of the solution remaining. How many ounces of solution did Mia start with? *

Answers

Given:

The solution decreased by [tex]\dfrac{9}{8}[/tex] ounces every hour for 5 hours.

Remaining solution at the end of the experiment = [tex]\dfrac{99}{8}[/tex] ounces.

To find:

The initial amount of solution.

Solution:

Let the initial amount of the solution be x.

The solution decreased by [tex]\dfrac{9}{8}[/tex] ounces every hour for 5 hours.

Total decreased amount [tex]=\dfrac{9}{8}\times 5[/tex]

[tex]=\dfrac{45}{8}[/tex]

Initial amount = Remining amount + Decreased amount of solution.

[tex]x=\dfrac{99}{8}+\dfrac{45}{8}[/tex]

[tex]x=\dfrac{99+45}{8}[/tex]

[tex]x=\dfrac{144}{8}[/tex]

[tex]x=18[/tex]

Therefore, the initial amount of solution is 18 ounces.

What are galaxies?

Galaxies are large areas that contain stars, dark matter, dust, interstellar gases, etc. It is a gravity-bound system that contains everything in its own place.

There are many galaxies, some are still undiscovered. Our galaxy in which the earth is present is called the Milky Way. It is called the Milky Way because due to many stars it looks like a shiny white path.

Now, the Big Bang Theory says that the universe is made up of expanding of a single point. And the universe is still expanding, so the galaxies' and other matters still going farther away.

Thus, the correct option is 2. Moving farther apart.
