what do you mean by photo synthesis?
Answer:
the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
Explanation:
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's metabolic activities.
All of these will produce genetic change within a population except -
A random reproduction
B natural selection
C chromosomal mutations
D genetic drift
Sunspots are connected with other or events solar hare A solar fare is a sudden release of energy from the Sun, which shoots hot charged partides plasma) from the Sun into
Strical and crcalgids When
Solar harest send enormous amounts of
energy and charged particles that can interact with the Earth's atmosphere. When the charged partides strike the atmosphere they can cause auroras and magnetic storms that can also disrupt
there are more Sunspots, this indicates that the Sun is more active and there will be more solar Hares.
It is under if there is a link between solar activity and changes in the Earth's climate because our planet's climate is influenced by so many other factors such as volcanoes and greenhouse gases. A period of time known as the Maunder
Minimum occurred from about 1645 until 1715. During this time period there yere almost no sunspots. This period occurred at about the same time as a period of cold temperatures known as the Little Ice Age. However, scientists have
not been able to determine if the two phenomen were actually related
Below is a graph of sunspot activity beginning in the year 1600
Which of the following claims would the sunspot evidence from the Maunder Minimum best support?
Moresunspots during this period would have increased magnetic storms.
Fewer sunspots during this period would have caused higher than normal greenhouse gas concentrations
Lower solar activity could have caused colder temperatures on Earth
Greater solar activity could have caused warmer temperatures of Earth.

the killifish is described as having tolerance to pollutants, Is this a
good thing or a bad thing? Explain
Answer:
good
Explanation:
having a tolerance to pollution means that the killfish can tolerate a certain mounts of pollution, so it won't be affected unless there is like a ton of pollution surrounding it
ow do cells use food to make energy and maintain homeostasis
Answer:
Cells obtain energy through the process of cellular respiration. It is a metabolic process of conversion of the biochemical energy from the nutrients into adenosine triphosphate (ATP). ... They exchange substances with the new cells and also eliminate the wastes thereby maintaining homeostasis.
Explanation:
There are several ion transport mechanisms within the cell membrane that function to maintain proper levels of solutes inside and outside the cell. ... This system uses the energy stored in ATP to pump potassium into the cell and sodium out of the cell.

which of the followimg could be reasons why popultion sizes may reach and maintaim plateaus? choose the three that apply
Will mark as brilliant answer
Answer:
Below :D
Explanation:
So basically, this question is asking what will cause a species' population to reach a point where it stops increasing.
Lets think about what can cause a lack of increase?
A decrease can cause this.
Or a slow in the rate of increase.
Now lets look at our selectable answers and see if any of them would fall under these two things.
First up is fewer deaths.
Well, fewer deaths basically means less of a decrease in population.
This is the opposite of decreasing the populatin count, and would instead raise it.
Next we have a limit in food supply.
This would cause a organism to starve and die.
So this would cause a decrease in population count.
So B is one of the answers
Next up is competition with other species.
When two species compete for a sort of resources, one massivly dies out due to outcompetion, and loses the resources needed to survive.
So this would also cause a large decrease in population count.
This makes C one of the answers
Next is increase in birth rates.
This would cause more organisms to be born of a species, basically increasing the population count.
This is the opposite of a decrease in population.
Next we have competition for space.
This is very similar to answer C, and the outcompeted species dies out due to lack of space.
So E is one of the answers
Now, the next answer seems viable, because major storms can kill off organisms, like hurricanes, earthquakes, and volcanos for instance.
However, as seen in many organisms over history, while these major storms kill of organisms, they can recover.
So although major storms decrease populations, they dont actually limit them.
In the end:
B is correct
C is correct
E is correct

A cell has 6 chromosomes. How many chromosomes will each daughter cell have if it undergoes mitosis
Answer:
At the end of mitosis, the two daughter cells will be exact copies of the original cell. Each daughter cell will have 30 chromosomes. At the end of meiosis II, each cell (i.e., gamete) would have half the original number of chromosomes, that is, 15 chromosomes.
hope this helps

Explanation:
Which of the following structures stores genetic information in both eukaryotic and prokaryotic cells?
A. Cytoplasm
B. DNA
C. Nucleus
D. Ribosome
2. Which of the following statements is true?
A Cells don't need nutrients.
B Chloroplasts contain a cell's
genetic material.
C Cells grow and reproduce.
D All nonliving things are made
of cells.
Answer: C. Cells grow and reproduce.
"All cells grow and reproduce. Eukaryotic cells reproduce through mitosis and meiosis, while prokaryotes reproduce through binary fission."
Explanation:
A. "Some essential nutrients are required for cellular function but cannot be produced by the animal body. These include vitamins, minerals, some fatty acids, and some amino acids. Food intake in more than necessary amounts is stored as glycogen in the liver and muscle cells, and in fat cells."
B. "Chloroplasts and mitochondria are subcellular bioenergetic organelles with their own genomes and genetic systems. DNA replication and transmission to daughter organelles produces cytoplasmic inheritance of characters associated with primary events in photosynthesis and respiration."
D. "Instead of cells, a non-living thing is made up of elements or compounds that form from chemical reactions. Examples of non-living things are rocks, water, and air."

Explanation:
A trout moves from a warm environment into a cold environment. Predict how the saturation status of hydrocarbon chains might change to ensure proper membrane fluidity in the new cold environment.
Answer:
The correct answer is - The hydrocarbons would become less saturated to increase the fluidity of the membrane
Explanation:
The ratio of saturated and unsaturated fatty acids or hydrocarbon chains is responsible for the membrane fluidity at cold temperatures. Cholesterol is an important part of membrane fluidity as it functions as a buffer, it inserts in phospholipids to preventing lower temperatures from inhibiting fluidity and at higher temperatures stabilizes the cell membrane and increase melting point and prevent increasing fluidity.
Moving from high temperature to low temperature hydrocarbon chains become less saturated in order to increase fluidity as it inserts cholesterols into phospholipids and decrease saturation.
