Answer:
yes
Explanation:
This time its with picture
Answer:
C. part X
Explanation:
Part X is showing the bases pairing up with each other, which is the process of transcription. You can verify this by making sure A is pairing with U, T is pairing with A, G is pairing with C, and C is pairing with G.
Part Y is incorrect because it is showing TRANSLATION rather than transcription, which are easy to mix up.
Part W is simply showing the DNA, while part Z is showing the polypeptide.

Which number remains unchanged during photosynthesis?
A. the number of water molecules
B. the number of carbon dioxide molecules
C. the number of glucose molecules
D. the number of carbon atoms
The number remains unchanged during photosynthesis is the number of carbon atoms.
Photosynthesis is a term to refer to the conversion of inorganic matter to organic matter thanks to the energy provided by sunlight.
This transformation is expressed in the following chemical function
6CO2 + 6H2O --sunlight -> C6H12O6 + 6O2.
As evidenced in the chemical function, the number of carbon atoms does not change because at the beginning and end of the reaction there are 6 carbons. However, other molecules such as water, glucose or carbon dioxide change as they degradate or combine with others.
Therefore, the correct answer is D. while options A, B and C are incorrect because they refer to elements that do change their number during this function.

Which of the following is true of DNA and RNA nucleotides? (4 points)
Both contain a sugar and a cytosine nitrogenous base.
Both contain a sugar and thymine nitrogenous base.
Both contain deoxyribose sugar and uracil nitrogenous base.
Both contain ribose sugar and cytosine nitrogenous base.
Answer:
Both contain a sugar and a cytosine nitrogenous base.
Explanation:
DNA and RNA are both nucleic acids. However, the nucleotides bases) that make up each molecule have slightly different structures.
DNA stands for deoxyribonucleic acid because the sugar in the nucleotides is deoxyribose sugar.
RNA stands for ribonucleic acid because the sugar in the nucleotides is ribose.
DNA contains the bases cytosine, guanine, adenine, and thymine.
RNA contains one base different, it has cytosine, guanine, adenine, and uracil.
Therefore, they contain different sugars, but they both contain a cytosine nitrogenous base.

rocks are classified into three major groups what are they
Answer:
There are three main types of rocks: sedimentary, igneous, and metamorphic. Each of these rocks are formed by physical changes—such as melting, cooling, eroding, compacting, or deforming—that are part of the rock cycle. Sedimentary rocks are formed from pieces of other existing rock or organic material.
Explanation:
There are four mechanisms that can cause changes in the frequencies of genes in populations: mutation, migration, genetic drift, and natural selection. All four are mechanisms of evolutionary change. What is genetic drift? A) In a population, it is the changes in allelic frequencies of a gene that are due to chance. B) A random error/change in the DNA sequence. These may be inherited or occur in cells during the lifetime of the organism. C) Also known as gene flow. It is any movement of individuals and/or the genetic material they carry, from one population to another.

Among unicellular eukaryotes, cell sizes differ greatly. Amoeba and Paramecium organisms are animal-like protists that are heterotrophic, have no cell wall, and are several times larger than most human cells. What might be some reasons why these unicellular organisms have larger cells than cells with similar traits (heterotrophic, lacking cell walls) that are found in multicellular organisms?
Such unicellular organisms have large cells to carry out all essential physiological functions like obtaining food, reproducing, movement, and others.
Unicellular organisms have different sizes generally have larger cell than multicellular organisms such as animal like protists. Animal like protists are large single-celled organisms, known as Protozoa that include Amoeba and Paramecium.
These cells have larger cell due to unicellular organisms have to fulfill all of it's requirements and provide space for various cell enzymes, organelles, other macromolecules and machineries within a single cell.They have to perform all characteristics of life, so they need a bigger cell for these functions.Thus, these cells have to perform all the physiological processes so required relatively bigger cell to function properly.

I have a huge test tomorrow and I need to know every thing about Cells, like the eukarotic cell, i need to know the cell membrane, and osmosis.
Answer:
look it up or ask your friends to look it upmaybe?
Explanation:
Answer:
Cell Definition“A cell is defined as the smallest, basic unit of life that is responsible for all of life’s processes.”
Cells are the structural, functional, and biological units of all living beings. A cell can replicate itself independently. Hence, they are known as the building blocks of life.
Each cell contains a fluid called the cytoplasm, which is enclosed by a membrane. Also present in the cytoplasm are several biomolecules like proteins, nucleic acids and lipids. Moreover, cellular structures called cell organelles are suspended in the cytoplasm.
Types of Cells.Prokaryotic CellsProkaryotic cells have no nucleus. Instead, some prokaryotes such as bacteria have a region within the cell where the genetic material is freely suspended. This region is called the nucleoid.
They all are single-celled microorganisms. Examples include archaea, bacteria, and cyanobacteria.
The cell size ranges from 0.1 to 0.5 µm in diameter.
the hereditary material can either be DNA or RNA.
Prokaryotes reproduce by binary fission, a form of sexual reproduction.
Eukaryotic CellsEukaryotic cells are characterised by a true nucleus.
The size of the cells ranges between 10–100 µm in diameter.
This broad category involves plants, fungi, protozoans, and animals.
The plasma membrane is responsible for monitoring the transport of nutrients and electrolytes in and out of the cells. It is also responsible for cell to cell communication.
They reproduce sexually as well as asexually.
There are some contrasting features between plant and animal cells. For eg., the plant cell contains chloroplast, central vacuoles, and other plastids, whereas the animal cells do not.
Functions of Cell:Provides Support and StructureFacilitate Growth MitosisAllows Transport of SubstancesEnergy ProductionAids in ReproductionCell Membrane The cell membrane supports and protects the cell. It controls the movement of substances in and out of the cells. It separates the cell from the external environment. The cell membrane is present in all the cells. The cell membrane is the outer covering of a cell within which all other organelles, such as the cytoplasm and nucleus, are enclosed. It is also referred to as the plasma membrane. By structure, it is a porous membrane (with pores) which permit the movement of selective substances in and out of the cell. Besides this, the cell membrane also protects the cellular component from damage and leakage. It forms the wall-like structure between two cells as well as between the cell and its surroundings. Plants are immobile, so their cell structures are well-adapted to protect them from external factors. The cell wall helps to reinforce this function.What is Osmosis?Osmosis is a passive process and happens without any expenditure of energy. It involves the movement of molecules from a region of higher concentration to lower concentration until the concentrations become equal on either side of the membrane.
Any solvent can undergo the process of osmosis including gases and supercritical liquids.
Osmotic Solutions There are three different types of solutions:An isotonic solution: is one that has the same concentration of solutes both inside and outside the cell.
A hypertonic solution: is one that has a higher solute concentration outside the cell than inside.
A hypotonic solution; is the one that has a higher solute concentration inside the cell than outside.
Effect of Osmosis on CellsOsmosis affects the cells differently. An animal cell will lyse when placed in a hypotonic solution compared to a plant cell. The plant cell has thick walls and requires more water. The cells will not burst when placed in a hypotonic solution. In fact, a hypotonic solution is ideal for a plant cell.
An animal cell survives only in an isotonic solution. In an isotonic solution, the plant cells are no longer turgid and the leaves of the plant droop.
The osmotic flow can be stopped or reversed, also called reverse osmosis, by exerting an external pressure to the sides of the solute. The minimum pressure required to stop the solvent transfer is called the osmotic pressure
Significance of Osmosis Osmosis influences the transport of nutrients and the release of metabolic waste products.It is responsible for the absorption of water from the soil and conducting it to the upper parts of the plant through the xylem. It stabilizes the internal environment of a living organism by maintaining the balance between water and intercellular fluid levels. It maintains the turgidity of cells. It is a process by which plants maintain their water content despite the constant water loss due to transpiration. This process controls the cell to cell diffusion of water. Osmosis induces cell turgor which regulates the movement of plants and plant parts. Osmosis also controls the dehiscence of fruits and sporangia. Higher osmotic pressure protects the plants against drought injury.What is a strand of DNA which functions as a section of the genetic code called?

Two cities are separated by 200 miles. City X has an altitude of 122 meters and City Y has an altitude of 260 meters. Calculate the altitude gradient between the two cites.
Answer: 0.69 m/ mile.
Explanation:
The altitude gradient between two cities X and Y = [tex]\dfrac{\text{Altitude of City Y - Altitude of city X}}{\text{Distance between two cities}}\times100\%[/tex]
Given: Two cities are separated by 200 miles.
City X has an altitude of 122 meters.
City Y has an altitude of 260 meters.
The altitude gradient between two cities X and Y =
[tex]\dfrac{260-122}{200}=0.69\text{m/ mile}[/tex]
Hence, the altitude gradient between the two cites = 0.69 m/ mile.
10. What would be an agricultural disadvantage to having a planting soil with high permeability?
Answer:
Excessive water loss
Explanation:
If the soil was super permeable than water would drain faster which could lead to excessive water loss which would not be good for crops
Having planting soil with high permeability will deprive crops of the necessary water and nutrient for growth.
Highly permeable soils have no capacity to retain water. they lose water at a very fast pace.
Lack of water retention means that the roots of plants will not be able to conduct the necessary water for metabolic activities in plants.
Thus, the growth and overall well-being of plants planted in such soils will be limited.
