Why do different colors affect photosynthesis differently
Answer:
Plants do respond differently to different colors of light being shone on them, because chlorophyll reflects green light and absorbs blue and red (therefore, blue and red are useful for photosynthesis, but green isn't).

what are the two product of the krebs cycle
Again, imagine that your liver, which has a volume of 2 liters, developed from a single embryonic precursor cell with a volume of 1000 μm3, or 1 x 10-12 liters. You previously calculated how many cell division cycles would be required for the precursor cell to produce your mature liver.
What if the control of liver organogenesis were a bit faulty, and the process went exactly 2 cell division cycles beyond this? What then would be the volume of your liver in liters?
I found that the answer to the first question is 41, but I can't figure out the second part.
Answer:
41 cycles
If cell division went 2 cell division cycle beyond the precursor; we have 43 cycles
The volume would be = 17.59 Litres
Explanation:
From the given information:
The number of cells in the liver that developed from an embryonic precursor is roughly [tex]\dfrac{2}{10^{-12}}= 2\times10^{12}[/tex]
The number of cell cycles needed to produce [tex]2\times 10^{12[/tex] cells is:
= [tex]log_2(2\times 10^{12})[/tex]
= 40.86
[tex]\simeq[/tex] 41
Thus, nearly 41 cycles of cell division are required to form the mature liver.
Now;
Suppose 2 extra cell division cycles took place;
The total number of cells would be 2⁴³ = 1.759 × 10¹³; &
The volume would be = 1.759 × 10¹³ × 10⁻¹²
The volume would be = 17.59 Litres

For this assignment, conduct some independent research on the raccoon and mountain gorilla. You may do your research online or from library books and magazines.
Part 1: Fill in the table below and then answer the questions.
Trait
How many offspring do they have in a year, usually? What do they eat?
Where are they found in the world?
How many are there in the world?
Are they hunted for meat, skin, fur, or other parts?
Part 2:
Which species is most vulnerable to extinction? Give at least three reasons why.
Which species would be most harmed by environmental change that wiped out one area of its habitat? Why?
Answer:
Raccoon:
1. Mother raccoons can have between two to five babies in a litter, and they will have just one litter per year.
2. Raccoons are omnivores, meaning they will eat both plants and other animals. This includes fruits, berries, nuts, fish, frogs, mussels, crayfish, insects, turtles, mice, rabbits, muskrats and bird eggs.
3. Raccoons can be found natively throughout most of the US and Canada, as well as in parts of Latin America, from Mexico extending down to the northernmost regions of South America.
4. There are only 323 to 955 left in the world.
5. They are hunted for their fur and skin.
Mountain Gorilla:
1. Once they have reached an age of approximately 10 years, female mountain gorillas give birth to one baby every 4 years.
2. They eat roots, shoots, fruit, wild celery, and tree bark and pulp.
3.Mountain gorillas are found in two separate locations: the Virunga range of extinct volcanic mountains on the borders of the Democratic Republic of Congo (DRC), Rwanda and Uganda, and in the Bwindi Impenetrable National Park in Uganda.
4. There are only about 1,000 mountain gorillas left.
5. Not only are they hunted for meat, mountain gorillas are also illegally hunted for trophies and live infants.
Part 2:
The mountain gorrila is most vulnerable to extinction. People hunt for mountain gorillas more than they hunt for raccoons. mountain gorillas are on the endangered list. Not only are the mountain gorillas hunted for their meat but they are killed as trophies. Raccoons are rarely out in the daytime making them harder to hunt.
The raccoons would be most harmed by environmental change. Raccoons live in trees and need places to hide in the day time. Gorillas would be able to adapt better considering they dont need to hide in the trees. Raccoons would then be out in the daytime making it easier for them to be caught.

Meteorologists refer to the water vapor in the atmosphere as
Answer:
^^ The answer is below ^^
Explanation:
Water vapor is water in the gaseous phase. Meteorologists have defined several different terms to express the amount of water vapor in air. ... Specific humidity is the ratio of the mass of water vapor in a sample to the total mass of the moist air, including both the dry air and the water vapor.
Meteorologists refer to the water vapour in the atmosphere as moisture or humidity.
What are water vapours?The atmosphere is continually being circulated with water. Water evaporating from the surface of the Earth rises into the sky on heated updrafts. When the air is driven by the wind, it condenses into clouds before returning to Earth as rain or snow. This cycle is vital to how heat and energy are moved around our globe from one location to another and from the Earth's surface to the atmosphere.
The most significant greenhouse gas found in the atmosphere is also water vapour. The heat emitted from the surface of the Earth is absorbed by water vapour molecules in the lower atmosphere. In turn, the molecules of water vapour emit heat in all dimensions. The Earth's surface receives some of the heat back. So, in addition to sunshine, water vapour serves as a second source of warming for the Earth's surface.
Therefore, meteorologists refer to the water vapour in the atmosphere as moisture or humidity.

Answer:
yes its important because...
Explanation:
Water is an essential feature of homeostasis in an organism. Water increases the volume of blood, which affects blood pressure and heart rate. Water dissolves gases and allow for efficient exchange and transport of oxygen and carbon dioxide. Water can be excreted, so it carries toxins that have been made water-soluble out of the body.

At which ocean-floor feature do plates move together?
Answer:
divergent plate boundaries
Explanation:
Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense.
What is a clue that the lac operon is on?
A.)Lactose is absent.
B.)The cell membrane changes.
C.)The repressor protein has fallen off the molecule.
D.)RNA polymerase is blocked by the repressor.
The correct answer is C.) The repressor protein has fallen off the molecule.
The lac operon is a regulatory system found in bacteria, which controls the expression of genes involved in lactose metabolism.
The lac operon consists of three main components: the structural genes (lacZ, lacY, and lacA), the promoter region, and the operator region. The regulation of the lac operon depends on the presence or absence of lactose and glucose.
In the absence of lactose, the lac repressor protein binds to the operator region of the operon, preventing the expression of the structural genes. This inhibits the production of enzymes involved in lactose metabolism.
However, when lactose is present in the environment, it acts as an inducer. Lactose is converted into allolactose, which binds to the repressor protein and causes it to undergo a conformational change. As a result, the repressor protein falls off the operator, allowing RNA polymerase to bind to the promoter region and transcribe the structural genes.
Therefore, the clue that the lac operon is on is the falling off of the repressor protein from the operator region, enabling gene expression and the production of enzymes required for lactose metabolism. Therefore, the correct answer is C.

Gross production is the amount of energy left after cellular respiration. Please select the best answer from the choices provided T or F
Answer:
FALSE
Explanation:
Gross production is the amount of energy left after cellular respiration that is false, as the gross production is the total production and the net production is the amount of energy left after cellular respiration.
What is the significance of the gross production?Gross production is the total amount of energy produced by an organism through different processes, such as photosynthesis, ingestion, and digestion of food, while after energy is used by the organism for cellular respiration, what is left is called the "net production." Although the gross energy is not released, the net energy is.
Hence, gross production is the amount of energy left after cellular respiration that is false, as the gross production is the total production and the net production is the amount of energy left after cellular respiration.

Explain why hunter-gatherer societies were highly mobile.
PLEASE HELP!!!
Answer:
Hunter and gatherer societies were highly mobile because if the place they they were staying ran out of resources they would have to move. The way that later societies would combat this is by planting farms which could grow back every year and allow them to stay in one place for long periods of time. Hope that helped!
Answer:
Hunter Gatherers rely on the land around them to keep them alive and well, with this being said , if a heard of Buffalo were to move away the village would starve because their main food source would be gone, so they have to “follow their food” and move with nature to stay alive.
