A student observes a cell under a microscope. She sees a cell wall and a nucleus. What type of cell is she observing?
O eukaryotic animal cell
O eukaryotic plant cell
O prokaryotic cell
O bacterial cell
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.

5 organelle cells not found in human cells
Hurry homework due in couple minutes
Answer:
Not every cell in the human body contains DNA bundled in a cell nucleus. Specifically, mature red blood cells and cornified cells in the skin, hair, and nails contain no nucleus. Mature hair cells do not contain any nuclear DNA. ... As part of the maturation process, human red blood cells destroy their cell nuclei.
This means they have no mitochondria, Golgi apparatus, or endoplasmic reticulum. They also lack a membrane-bound nucleus, although they do have genetic material located in a nucleoid region. Prokaryotic cells are surrounded by a plasma membrane, and some types of bacteria have cell walls as well.
Nucleolus. Within the nucleus is a small subspace known as the nucleolus. It is not bound by a membrane, so it is not an organelle. This space forms near the part of DNA with instructions for making ribosomes, the molecules responsible for making proteins.
Explanation:
Describe how an enzyme speeds up a chemical reaction within a cell. (written answer)
Answer:
Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.
Looking for input and other opinions with the following statement. 'environmental factors influence the rate of natural selection." I am to make a claim on whether I agree or not and why. I agree with the statement. This is because all literature states that with natural selection it's basically the best man/woman wins. I feel that with that statement it directly refers to the environment if food is scarce then the best hunter the best runner is going to get the food first if the weather is changing and it's time to move on or hibernate then the one with the best intuitions will move on or assume hibernation and wont be left to the cold as well as if they are the prey to something else as everything is the best one to keep alert and observant to their surrounding would be the one to survive longer. Although I think that the only downfall to that would be if something happened and the appearance was to change and made them less desirable in that manner but then would in turn help themselves to camouflage to hide better.
I agree completely.
Environmental factors control evolution through surivial of the fittest, or natural selection. This is not nearly as much the case with humans as wild animals, or early on humans, but it does still come into play. For example, lactose intolerance was erradicated in areas where milk was a primary source of nutrients during a famine. The famine was environmental, causing natural selection to elimate lactose intolerant people in the area.
A more basic example is fur color of certain animals. They were selected by their environment to survive and pass on their genetics, causing the species to evolve.
You have a friend who became stranded in a blizzard without food for
several weeks. This friend, when rescued, had lost about 7 kg (about 15
Ibs). As he was quite healthy to begin with, he assumed the weight he
lost was stored fat, but he wondered where the fat had gone, How did
the fat leave his body?
The fat didn't really leave his body. Fat was converted to glucose in the gluconeogenesis pathway to give him energy during the period of starvation.
Fat is stored in the body in the adipose tissue. Fat plays so many roles in the body such as;
Protection of vital organsInsulating the body from coldServing as an energy storeIn times of starvation, fact could also be broken down to release energy. This occurs when fat is broken down to glycerol and fatty acids. When this occurs, glycerol goes to the liver where it is converted to glucose in the gluconeogenesis pathway. This helps to produce energy in times of starvation thereby depleting the body's fat reserve.
As this process occurs, the fat reserve in my friend's body kept going down resulting in his loss of about 15 Ibs of weight.

what do you think will happen when i put a leaf discs saturated with a sodium bicarbonate solution and put it under a lamp ? will it sink or float and why ? can someone help me rq will give 30 points
Answer:
the leaf disk should float because bicarbonate is the source of its oxygen for photosynthesis and it releases oxygen into the interior of the disk causing it to float.
Explanation:
The thing which would happen if leaf discs are saturated with a sodium bicarbonate solution and put under a lamp is:
The leaf disk would floatAccording to the given question, we can see that there is an experiment which is taking place as a leaf disc is placed in a solution of sodium bicarbonate under a lamp.
As a result of this, we can see that the source of oxygen for the leaf disk is the bicarbonate and when the chlorophyll in the plant reaches out to the lamp for photosynthesis, it would make the leaf disk to float.

Answer:1).A nonrenewable resource is a natural substance that is not replenished with the speed at which it is consumed. It is a finite resource.
2)Rocks are made of minerals, like quartz, calcite, feldspars, and micas. Most rocks are made from more than one mineral, but there are quite a few kinds that are made from only one mineral. Minerals are not rocks, rocks are made of minerals.
3)Coal is a very useful rock that formed over millions of years from the ... No, coal is not a mineral because coal is made of dead plants.
4)The relatively cheap cost of fossil fuels is a major positive aspect. They are in abundant supply, which makes them inexpensive to drill or mine for. In particular, coal is one of the most widely available fossil fuels.
5)High initial costs for material and installation and long ROI (however, with the reduction in the cost of solar over the last 10 years, solar is becoming more cost feasible every day) Needs lots of space as efficiency is not 100% yet. No solar power at night so there is a need for a large battery bank.

why organisms need specialised cells and tissues in order to survive
Multicellular organisms require cells to perform various functions and collaborate to maintain a balance in the system known as homeostasis. As a result, specialized structures become specialized for specific functions.
What is cell specialization?Cell specialization, also recognized as cell differentiation, is the methodology by which formulaic cells transform into specific cells that perform specific functions within the body.
Cell specialization is especially important during embryonic development.
Cell specialization allows multicellular organisms to express fewer genes in individual cells, protecting genes from mutagen damage.
Cell specialization occurs primarily during embryonic development as a result of cell signaling of cytoplasmic determinants.
Adult stem cells become specialized to various types of stem cells primarily due to gene expression regulation.
Cells in multicellular organisms must perform a variety of functions and collaborate to maintain a balance in the system known as homeostasis. As a result, specialized structures evolve to perform specific functions.
Thus, the organisms need specialized cells and tissues in order to survive.
