Answers
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.

Incomplete dominance is an example of a non-mendelian trait (doesn't follow the genetic rules established by Gregor Mendel). When two parents mate and produce offspring, the offspring is a blend of the two parents. So, a red flower and a white flower would make a pink flower.
Using context clues, what does “ferrying its newly-gained energy with it “ mean when talking about convection?
Answers
The term "ferrying its newly-gained energy with it" means that the fluid carries the energy it acquired as it rises during convection.
Convection is a mode of heat transfer in which energy is transferred by the bulk movement of particles from one point to another. During convection, a fluid is heated and its particles acquire energy, These energetic particles now move upwards and are replaced by less dense fluid at a lower energy.
The term ferrying its newly-gained energy with it, implies that the heated particles carry the energy they have gained with them as they rise during convection.

Answers
Answer:
(Hope this helps can I pls have brainlist (crown)☺️)
Explanation:
ATP synthase is a protein that catalyses the conversion of adenosine diphosphate (ADP) and inorganic phosphate to the energy storage molecule adenosine triphosphate (ATP) (Pi). It's classed as a ligase since it modifies ADP by forming a P-O bond (phosphodiester bond).
Cells store energy in the form of ATP. These storage molecules are made in the mitochondria, which are small organelles present in eukaryotic cells and are commonly referred to as the cell's "powerhouse."

If you reduced three sponge species down to individual cells using a very fine cloth and mixed them together, what would you predict would be the outcome after a period of time? Make sure to identify why, and what proteins are likely responsible.
Answers
After a few hours, the cells of each sponge would re-aggregate and form three new sponges.
We can reach this answer because:
The sponge is a multicellular organism with little cell differentiation.The surface of sponge cells has a group of glycoproteins, which allow communication between all the cells in a sponge.These proteins are transmembrane receptors, which emit signals responsible for the cell adhesion process.The cell adhesion process allows the cells in a sponge to regroup if they are separated.In this case, if three sponges had their composition sieved and mixed, the glycoproteins of their cells would allow each sponge to be remade, as there would be communication and a regrouping of the cells of each sponge.

Answers
Answer:
Most people are familiar with three states of matter – solids, liquids and gases – but there are two more that are less commonly known but just as important – plasmas and Bose-Einstein condensates. They are very compressible (particles are widely spaced). There are three states of matter: solid; liquid and gas. They have different properties, which can be explained by looking at the arrangement of their particles.
atoms
An atom is the smallest particle of an element, having the same chemical properties as the bulk element. The first accurate theory explaining the nature of matter was Dalton's Atomic Theory: 1. All matter is composed of atoms, and atoms are indivisible and indestructible.
What are the 8 states of matter?
Bose–Einstein condensate.
Fermionic condensate.
Degenerate matter.
Quantum Hall.
Rydberg matter.
Rydberg polaron.
Strange matter.
Superfluid
Answer:
1. Liquid, Solid, Gas
2. Solid has a set shape. Solid can move but gas and liquid is more flexible than solid.
3. Solid has a fixed volume while liquid and gas takes the volume of its container. Solid stays in one place while gas and liquid are flexible.
4. A. The stronger the intermolecular forces in a liquid the higher the boiling point. Therefore, water has a stronger intermolecular force than ethanol.
B. Water molecules are more attracted to each other than ethanol (alcohol) molecules, because water has more hydrogen atoms bonded to oxygen. ... So, that's why alcohol has a much lower freezing point
5. Ionic charges are stronger.
Covalent bonds are known to have the strongest and most stable bonds since they go deep and into the inter-molecular state. A diamond is an example of a compound with this characteristic bond.
Ionic bonds are the next strongest molecular bond following covalent bonds. This is due to the protons and electrons causing an electro-static force which results to the strong bonds. An example would be Sodium Chloride (NaCl), which when separated is Na⁺ and Cl⁻.
Van der Waals forces, also known as Dispersion forces, are the weakest type of molecular bonds. They are only formed through residual molecular attractions when molecules pass by each other. It doesn't even last long due to the uneven electron dispersion. It can be made stronger by adding more electrons in the molecule. This kind of molecular bonds appear in non-polar molecules such as carbon dioxide.

5 organelle cells not found in human cells
Hurry homework due in couple minutes
Answers
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.

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.
Answers
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.

why organisms need specialised cells and tissues in order to survive
Answers
the cells get oxygen and nutrients from this extracellular fluid and release waste products into it. Humans and other complex organisms have specialized systems that maintain the internal environment, keeping it steady and able to provide for the needs of the cells.
systems of specialized cells within organisms help them perform the essential functions of life, which involve chemical reactions that take place between different types of molecules, such as water, proteins, carbohydrates, lipids, and nucleic acids. All cells contain genetic information in the form of DNA molecules.
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.
