QWERTY
Explanation:
Which of the following is NOT a part of cell theory a.All living things are made of one or more cells. b.All cells are Eukaryotic cells. c.Cells are the basic unit of life. d.Cells come from pre-existing cells.
Option b. "All cells are Eukaryotic cells" is not a part of cell theory.
Cell theory refers to the belief that all living things are made up of one or more cells that unite to form the whole body/structure/organism.
It is universally known that cells are the smallest unit of living things. Without them, there can be no structure or organism made or formed. Cell theory provides the basic description of the properties of cells. And this cell theory was developed by three major scientists- Matthias Schleiden, Theodor Schwann, and Rudolf Virchow. The trio believed that cells, being the alpha of human life, are an important element of living things. They then came upon three basic points that they term "cell theory", which states that all living things are made of one or more cells. They also stated that cells are the basic unit of life and that they come from pre-existing cells. And that cells can be either one of the two- Eukaryotic or Prokaryotic cells. The statement that all cells are Eukaryotic in nature is false because Eukaryotes are cells with a clearly defined nucleus. This means that larger organisms like animals, plants, and fungi are Eukaryotes whereas smaller ones like bacteria and Archaea do not have a membrane-bound nucleus, making them Prokaryotes.While it is understood that cells are the basic unit for living beings, there are certain points that make them important. But one statement that is wrong about the cell theory is that all cells are Eukaryotic cells. Thus, option b is the correct answer.

why grapes swell when placed in water
When grapes are soaked in water, the grapes then swell up because grape's cells have a high concentration of solutes in comparison to the water. In other words, grapes have low concentration of solvent (that is water molecules ) in comparison to the concentration of solvent in water. In this situation, there will happen a process known as osmosis in which water molecules moves from a region of concentration of water to a region of low concentration of water through a semipermeable membrane. (the cell membrane of the grape's cell is also semipermeable,which only allows solvent molecules to pass through it)

Explanation:
DNA has the appearance of a _____. DNA has the appearance of a _____. single strand letter U double helix triple helix circle
Answer:
double helix
Explanation:
Deoxyribonucleic acid, commonly known as DNA, consists of two long polynucleotide chains composed of four types of nucleotide subunits i.e. A, G, C, T. Each chain is called a strand. Each nucleotide is made up of a pentose sugar, phosphate group and a nitrogenous base.
DNA is a double-helical structure that contains each strand in a spiral or coiled form. This double helix structure forms when two complementary strands are held together by hydrogen bonds. The bonding occurs between the nucleotide base portions of the complementary strands e.g G-C, A-T.
What type of bonds within the tertiary structure of an enzyme will break at high temperatures? Which bonds will not break?
Answer:
The bonds that will break at high temperature are hydrogen, ionic and Van der Waal's interactions. Covalent bonds will not break.
Explanation:
Answer:
Bonds in the tertiary structure of an enzyme include the covalent ,hydrogen, ionic , as well as Van der Waal's interactions.
An Enzyme is a chemical catalyst found in living organisms which helps to regulate the biochemical processes of the body. An example includes pepsin, ptyalin etc.When heat is applied to an enzyme, the unique structure is usually altered in the process known as Denaturation.
Bonds such as the hydrogen ,ionic and Van der waals force are broken when subjected to high temperatures. The covalent bond however , doesn't get affected or broken which is because it is stronger as a result of its formation involving the sharing of electrons.This makes it more stable and tightly held together.

why aren't all the cells in our body totipotent our entire lives
Answer:
somatic cells have highly specific functions
Explanation:
In our body, the major part of cells is irreversibly differentiated into somatic cells. From a cellular point of view, this process of differentiation seems to be an evolutionary disadvantage. However, cellular differentiation is a process aimed at exploiting the genetic variation in order to obtain a highly specialized cell type that is capable of carrying out a specific cellular function. For example, keratinocytes are highly specialized epithelial cells that function by separating the organism from the surrounding environment.

Heterotrophic by ingestion
Which student's classification correctly separates organisms into these two kingdoms?
A. Student 1
B. Student 2
C. Student 3
D. Student 4
The classification made by student 3 correctly separated the organisms into Plant and Animal Kingdom on the basis of presence of cell wall. Thus, the correct option is C.
What is the difference between Plant cell and Animal Cell?The living organisms are classified into five major Kingdoms, from which the most complex and advance organisms belongs to the Plant and Animal Kingdom.
Plant Kingdom consist of all the organisms which show the presence of a cell wall, autotrophic mode of nutrition, and immobile in nature. Whereas, the animal kingdom consist of all the organisms which show the absence of a cell wall, heterotrophic mode of nutrition, and are mostly mobile and capture the food on their own.
The main difference between Plants and Animals is the cell wall, plant cells have an outermost cell wall in their cell which is absent in animal cell.
Therefore, the correct option is C.

What is the INDEPENDENT variable?
Answer:
The correct answer would be : wet or dry environment.
Explanation:
Independent variable is a variable that can be changed or manipulated by the researcher or student in order to carryout study on the response on dependent variable.
In this case or experiment, researcher can make environment of the container wet or dry, however it is depend on pilbugs to go which type of environment or side and stay for what time.
Thus, the independent variable would be wet or dry container.
Which approach to ecological investigations is illustrated by Biosphere 2? Defend your classification.
Answer:
The correct answer is : Biosphere 2 is a model based on the creation of a miniature ecosystem with life support systems.
Explanation:
Biosphere 2 is a small model of the biosphere, which is planned by scientists and engineers, that is closed and isolated from the outside world. In this study or research, the strategy for modeling is utilized to show the performance and conduct or behavior of a real biosphere.
Researchers made a model or an artificial situation that can uphold living things. It has a scaled-down model of a tropical forest, a grassland, a sea with a coral reef, a desert, and a mangrove biosphere. In these conditions, a wide range of animal varieties was contained. Furthermore, a group of eight individuals additionally fixed themselves inside it.

Answer:
proximate explanation
Explanation:
In biology, a proximate explanation refers to an event that is directly responsible for producing a specific result. A proximate explanation allows to explain a particular biological phenomenon immediately associated with physiological factors. In sociology, a proximate explanation enables understanding of human behavior by their more immediate factors. On the other hand, an ultimate explanation is believed to be the real cause of the observed results.
