Answer:
eukaryotic plant cell
hope this helps
Only eukaryotic plant cells have a cell wall and a nucleus. Option 2 is correct.
Eukaryotic cells are cells that have a nucleus and other membrane-bound organelles. Prokaryotic cells do not have a nucleus or other membrane-bound organelles.
Plant cells are eukaryotic cells that have a cell wall. The cell wall is a rigid structure that surrounds the cell membrane. It provides support and protection for the cell. Animal cells do not have a cell wall.
The nucleus is the control center of the cell. It contains the DNA, which is the genetic material of the cell. The nucleus also contains proteins that control the activities of the cell.
So, if a student observes a cell under a microscope and sees a cell wall and a nucleus, she is observing a eukaryotic plant cell.

Explain how scientists use geologic time to determine the age of landforms.
Answer:
scientists have developed four different methods of determining the age of the earth. By using these methods, or a combination of them, the age of geological formations created by past events and even the fossilized bones of prehistoric animals can be determined.
Based on the research done by scientists, the Geologic Column, a graph that illustrates earth age, was developed. The Column, with its names for the epochs and eras of time, illustrates what scientists think was taking place in earth history. The three primary methods are:
Radiation Measurement
Stratigraphic Superposition
The Fossil Record
From these methods of dating, scientists have determined that the earth as we know it seems to be about 4.6 billion years old. It is theorized that the earth got its start as a result of what is called the "Big Bang nearly 6 billion years ago. The Big Bang theory holds that all the planets, stars, solar systems, galaxies, etc., are the result of a huge explosion that sent material speeding through space. As time passed, the gravitational force of larger chucks of material attracted the smaller chunks and formed the galaxies and solar systems we see today.

History of Present Problem:
Frank was driving home after a long day at work. It was late and he was having problems driving in the dark with so
much traffic. He was forced to take a detour and felt tired, so he took another sip of soda. "What would I do without
sugar and caffeine?" he mumbled to himself. Frank realized that he should probably stop the car as he noticed his hands
begin to shake, but he continued anyway. Rounding a corner, he realized that he was having trouble focusing on the
road. He tried to blink away the blurriness and shook his head, but things did not change. In an instant, the car slipped
off the road and hit a tree. "What was that?" exclaimed Frank to the night air. He quickly got out of the car and checked
himself out. Other than the shock of the accident, Frank seemed to be okay. He pulled out his cell phone and called his
wife, Stacey, to come pick him up. He then called to report the accident to the police and his insurance agent. His wife
arrived about an hour later and looked very concerned when she saw Frank sitting in the police car. "Why aren't you
going to the hospital?" screamed Stacey. "Were you drinking again?" "I'm fine, and no I wasn't drinking. Check with
Sergeant Eversman if you do not believe me. I lost focus; it has been a long day and my vision is a little off. This is too
much stress. Please, I just want to go home." The emergency staff checked him out and recommended he go to the
hospital for evaluation but Frank declined. They drove home, but Stacey continued to badger Frank about going to the
hospital.
Answer:
Frank might have been an alcoholic.
Explanation:
Because his wife,Stacey,asked him if he had been drinking and he also didnt want to go to the hospital for evaluation.

Explanation:
is a chemical substance that is produced in substantial quantities, and is reasonably expected to be released in to the environment in substantial quantities a risk trigger, standard trigger, or an exposer trigger?
Means that the EPA has made a determination that a chemical or biological agent may present an unreasonable risk both in toxicity and exposure.
a. exposer trigger
b. standard trigger
c. risk trigger
Answer:
c-risk trigger
Explanation:
The Risk Evaluation process is the second step, following Prioritization and before Risk Management, in EPA’s existing chemical process under TSCA. The purpose of risk evaluation is to determine whether a chemical substance presents an unreasonable risk to health or the environment, under the conditions of use, including an unreasonable risk to a relevant potentially exposed or susceptible subpopulation. As part of this process, EPA must evaluate both hazard and exposure, exclude consideration of costs or other non-risk factors, use scientific information and approaches in a manner that is consistent with the requirements in TSCA for the best available science, and ensure decisions are based on the weight-of-scientific-evidence.

How Enzymes Function Enzymes are biological catalysts. They can increase the rate of chemical reactions as much as a millionfold by lowering the energy barrier of a reaction.
Part A - Enzymes and activation energy The graph presents three activation energy profiles for a chemical reaction (the hydrolysis of sucrose): an uncatalyzed reaction, and the same reaction catalyzed by two different enzymes. Rank these by reaction rate, as measured by the rate of product formation (from the most product formed to the least product formed). To rank items as equivalent, overlap them.
Part B - Factors that affect enzymes Complete this vocabulary exercise relating to enzymes. Match the words in the left-hand column to the appropriate blank in the sentences in the right-hand column. HelpReset cofactor specific denatured substrate active site catalyst complex
1. An enzyme is when it loses its native conformation and its biological activity.
2. An enzyme is considered a because it speeds up chemical reactions without being used up.
3. An enzyme is considered because of its ability to recognize the shape of a particular molecule.
4. A , such as a vitamin, binds to an enzyme and plays a role in catalysis.
5. When properly aligned, the enzyme and substrate form an enzyme-substrate (ES) .
6. A substrate binds to an enzyme at the , where the reaction occurs.
7. In a catalyzed reaction a reactant is often called a _________.
Answer:1. An enzyme is denatured when it looses its native conformation and its biological activity. Enzyme is a protein and at high temperatures, the shape of the proteins is altered, preventing it from its function. In addition change in pH above optimal may also cause denaturation of enzymes inactive.
2. An enzyme is considered a catalyst because it speeds up chemical reaction without being used up. A catalyst is a substance that speeds up chemical reactions by reducing the activation energy of the reactants, they are not consumed during the reactions. Enzyme are biochemical catalysts that speeds up chemical enzymatic reactions without being consumed just like normal catalysts.
3. An enzyme is considered specific because of its ability to recognize the shape of a particular molecule. One property of enzyme is that they are substrate specific and will act on specific substrate, others will act on a specific type of chemical bond or functional group, while others will catalyze only one reaction (absolute specificity)
4. A cofactor such as a vitamin, binds to an enzyme and plays a role in catalysis. Cofactors are mostly metal ions (such as Zn ions or iron ions) or coenzymes are inorganic and organic chemical that aid the activity of enzymes. Coenzymes are non protein molecules mostly vitamins or vitamins derivatives that enhance enzyme activity.
5. When properly aligned, the enzyme and substrate form an enzyme-substrate (ES) complex. Es complex is the intermediate formed when a substrate molecule interacts with the active sites of an enzyme. After the formation of the complex then the substrate undergoes a chemical reaction and is converted to product.
6. A substrate binds to an enzyme at the active-site, where the reactions occurs. Active sites is a region on the enzyme where substrate molecules bind and undergoes a chemical reaction where it is converted to product. These sites contain the binding site and the catalytic site.
7. In catalyzed reaction, a reactant is often called a substrate. Substrate molecule is the substance that is acted upon by an enzyme and is converted to a product. The substrate forms an interaction with the binding site of the active site then the catalytic site of the active site converts the substrate to a product during catalysis.
1. Denatured
2. Catalyst
3. Specific
4. Cofactor
5. Complex
6. Active Site
7. Substrate
The induced fit model states an substrate binds to an active site and both change shape slightly, creating an ideal fit for catalysis. When an enzyme binds its substrate it forms an enzyme-substrate complex. ... The enzyme will always return to its original state at the completion of the reaction.
"The active site of the enzyme has a complementary rigid structure" belongs to the key and lock system

how plating trees can be a problem
Answer:
(Hope this helps can I pls have brainlist (crown)☺️)
Explanation:
There are even more serious issues, as trees have several ways of influencing the climate. The first problem is that trees are dark in comparison to other things that could cover the ground, such as grass or snow. Planting more trees, as a result, tends to make the terrain darker.
Tree planting on a large scale is becoming a more popular part of worldwide efforts to fulfil climate objectives. Forests, on the other hand, are complex ecosystems, and haphazard planting can actually raise carbon dioxide (CO2) levels in the atmosphere, contributing to global warming.
Fact: Trees grow slowly
