what cause's cell division
Cells divide for many reasons. For example, when you skin your knee, cells divide to replace old, dead, or damaged cells. ... When organisms grow, it isn't because cells are getting larger. Organisms grow because cells are dividing to produce more and more cells

In your own words, give a brief overview of the process of photosynthesis. Include where each phase place within a plant cell.
Answer:
Photosynthesis has two parts: the light-dependent reactions and the dark reactions (the Calvin cycle). Photosynthesis in a general sense, uses CO2 and water to create C6H12O6 (glucose) and oxygen. The light-dependent reactions use water to make oxygen, and a reduced energy carrier (NADPH) is also created. The Calvin cycle uses carbon dioxide and ATP to create G3P for glucose.
The light-dependent reactions occur on the membrane of the thylakoid and also involve shuttling electrons across different complexes (photosystem II and photosystem I), eventually causing ATP to be created with a proton gradient.
The light-independent reactions/Calvin cycle occur in the stroma of the chloroplast and also involve shuffling carbons around. Carbon dioxide is processed in three stages, and glucose is made from 6 CO2.
If a rock was determined to be around 3.9 billion years old how much Potassium 40 would be left in that rock sample? (Percentage of Potassium 40)
What percent of potassium-40 remains undecayed in a rock that is 3.9 billion years old? The 3.9 billion year old rock has undergone three half-lives (3.9 divided by 1.3 = 3). After 3 half-lives, 12.5% of the potassium-40 remains undecayed.

In a biological reaction involving an enzyme, what does the substrate bind to? the active site of another substrate the inactive site of an enzyme the inactive site of another substrate the active site of an enzyme
Answer: The part of the enzyme where the substrate binds is called the active site (since that's where the catalytic “action” happens). ... Thanks to these amino acids, an enzyme's active site is uniquely suited to bind to a particular target—the enzyme's substrate or substrates—and help them undergo a chemical reaction. To catalyze a reaction, an enzyme will grab on (bind) to one or more reactant molecules. These molecules are the enzyme's substrates. In some reactions, one substrate is broken down into multiple products. ... The products then leave the active site of the enzyme.
Explanation:
Answer:
the active site of an enzyme

Answer:
C
Explanation:
it literally says that the lions used to look different, thus proving the evolution theory
I dont understand what they are asking please help!!
Answer:
"Phenotype" would mean the two letter combination of traits that make up this trait. For example, heterozygous would be something like "Cc", with the "C" representing a dominant trait and "b" representing a recessive trait.
In this case, the answer would look something like "CC", though I'm not sure the exact letters this question is using. Good luck!

How would you explain why bicarbonate and digestive enzymes respond differently in two of the variables in Figure 30–8?
Answer:
Bicarbonate will helps for neutralize acid and it is the base for Highly pH. To find the solution the sodium bicarbonate with an rule to get an idea of pH.
The main enzymes of digestive in the juice pancreatic as listed below. They where many efforts which will have suitable for an pancreatic insufficient exocrine with specially designed enzyme for the preparations. They are several disadvantages with an physiological enzyme secretion.
Explanation:
They respond differently in hydrochloric acid and in fat because fats have a higher response to digestive enzymes because they break up fats, whereas bicarbonate's response to hydrochloric acid is higher because it neutralizes acid.
Hope that helps!

You are part of a small group of humans rocketed at “warp speed” to Planet X, without any books, weapons, or technology. Planet X has no ozone layer to protect its surface from cancer-causing ultraviolet radiation, but native plants and animals have evolved to live safely there. Below the surface, the planet has a network of underground tunnels, just a meter high, which are inhabited by carnivorous predators.
Write 3 paragraphs using the vocabulary words we discussed today in class about how descendants of the group of humans would look and act after evolving for 100,000 years on Planet X.

• Evolution
• Mutation
• Non-random Mating
• Gene Flow
• Genetic Drift

Explain why bacteria are essential parts of the nitrogen cycle.
Answer:
The most important part of the cycle is bacteria. Bacteria help the nitrogen change between states so it can be used. When nitrogen is absorbed by the soil, different bacteria help it to change states so it can be absorbed by plants. Animals then get their nitrogen from the plants.
Explanation:
Hope this helps
Answer:
Bacteria are a very important part of the nitrogen cycle because it helps to change or fix nitrogen into a usable form. Interesting Nitrogen Cycle Facts: Plants absorb nitrogen directly from the soil.

What is this plant tissue?
Answer:
microchondrian i think
Explanation:
The accidental introduction of invasive species of plants and animals often
causes severe problems in the ecosystem where they are introduced. One such
example is in Texas. The Rasberry crazy ant (Nylanderia pubens) which is thought
to have arrived in 2002 from South America. This ant species is known to attack
livestock, displace existing species, and damage electrical equipment. N pubens
consumes "honeydew," a sugary liquid substance secreted as a waste product by
aphids, which suck the sap out of plants.
Which of the following statements best explains the impact that N. pubens has
on its environment?
Answer: N. pubens has found a place within the existing food web in its new environment.
Explanation:
The statement that best explains the impact that N. pubens has on its environment is that "N. pubens has found a place within the existing food web in its new environment".
From the information given, it's stated that the Rasberry crazy ant (Nylanderia pubens) was accidentally introduced in Texas and it attacks livestock, displace existing species, and damage electrical equipment.
It's further stated that it consumes "honeydew," a sugary liquid substance secreted as a waste product by aphids, which suck the sap out of plants.
This shows that it has found a place within the existing food web in its new environment.

An animal that does not have the traits to adapt to its surroundings will?
Explanation: If organisms cannot adapt to the changes in their ecosystem, they may move to another location. If they will not move, the species may become threatened, endangered, or extinct. Under an evolutionary phenomenon called relaxed selection, traits that were advantageous in one time and place become obsolete in another. Traits that aren't actively maintained by natural selection tend to become smaller or less functional over time, studies suggest.
