Answer:
Explanation:
A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. In contrast, animal cells have many, smaller vacuoles. Plant cells have a cell wall, as well as a cell membrane. In plants, the cell wall surrounds the cell membrane.
Answer:Las células vegetales tienen una pared celular, así como una membrana celular. En las plantas, la pared celular rodea la membrana celular. Esto le da a la célula vegetal su forma rectangular típica. Las células animales solo tienen una membrana celular, y carecen de pared celular.
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.
The mitochondria are organelles that convert food into ATP, energy your cells can use. The text describes the mitochondrion as an organelle with two membranes, an outer and inner. Using evidence from the text, describe the inner membrane and how it is able to increase its ATP production due to this membrane.
Answer:
Causes oxidative phosphorylation.
Explanation:
The mitochondrial inner membrane is the site of the electron transport chain which is an important step in aerobic respiration because the inner mitochondrial membrane converts energy through oxidative phosphorylation which is the main process that is responsible for the production of energy in the form of ATP. There is inter-membrane space between the inner membrane and outer membrane where ATP synthase, an enzyme embedded in the inner mitochondrial membrane that is responsible for high ATP production.
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.
how long does copper deposits takes to form
Answer: 2 days and 14 hours
Explanation:
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!

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

How do you're muscles & skeleton work together?
The bones of the skeletal system serve to protect the body's organs, support the weight of the body, and give the body shape. The muscles of the muscular system attach to these bones, pulling on them to allow for movement of the body.

Explanation:
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.
Use these vocabulary words:
• Evolution
• Mutation
• Non-random Mating
• Gene Flow
• Genetic Drift

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.

Answer:
the active site of an enzyme

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.

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.

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.
