A student is conducting a breeding experiment. She knows the genotype of one parent plant and concludes that she can use a Punnett square to predict the outcome of crossing the plant with another plant. Which statement best explains why this conclusion is incorrect?
a. She needs to know the phenotypes of the previous plant generation.
b. She needs to know the phenotype of the first plant.
c. She needs to know the genotypes of the previous plant generation.
d. She needs to know the genotype of the second plant.
D. She needs to know the genotype of the second plant.
What is a punnett square?A Punnett square is a tool used to predict the outcome of a genetic cross between two individuals. To use a Punnett square, you need to know the genotypes of both of the individuals involved in the cross. In this case, the student knows the genotype of one parent plant, but does not know the genotype of the second plant.
Therefore, she cannot use a Punnett square to predict the outcome of the breeding experiment. In order to do so, she would need to know the genotype of the second plant.

Cell membranes are made up of a bilayer of phospholipids that are very selective about what substances can pass through.The table below shows the different types of molecules that can enter a cell. It compares the concentration on the outside to the inside of the cell, its relative size, and whether it is polar, nonpolar, or an ion. Determine how each molecule can pass into the cell. Is it by passive transport, active transport, or endocytosis? (3 points)
Answer:
Answer: Oxygen = passive Carbon Dioxide = passive Fructose = Endosytosis glutamine = Active Sodium ion = Active Potassium ion = Active Protein molecule = Passive or Endocytosis
Explanation:
js trynna get points lol
The molecules can pass into the cell by passive transport, active transport, or endocytosis.
Molecule | Concentration Outside | Concentration Inside | Size | Polarity | Transport | Mechanism
Glucose High Low Small Polar Diffusion
Oxygen High Low Small Nonpolar Diffusion
Sodium High Low Small Ion Active transport
Chloride Low High Small Ion Active transport
Amino acids Low High Medium Polar Carrier-mediated transport
Large protein Low High Large Polar Endocytosis
Glucose and oxygen can pass into the cell by diffusion. Diffusion is the movement of molecules from an area of high concentration to an area of low concentration. Glucose and oxygen are both small molecules, and they are both polar. This means that they can dissolve in the phospholipid bilayer of the cell membrane.
Sodium and chloride can pass into the cell by active transport. Active transport is the movement of molecules from an area of low concentration to an area of high concentration. Sodium and chloride are both ions, which means that they are charged particles. This means that they cannot dissolve in the phospholipid bilayer of the cell membrane. Instead, they need to be transported across the membrane by special proteins called ion pumps.
Amino acids can pass into the cell by carrier-mediated transport. Carrier-mediated transport is a type of passive transport that uses carrier proteins to transport molecules across the cell membrane. Amino acids are polar molecules, but they are larger than glucose and oxygen. This means that they cannot simply diffuse across the cell membrane. Instead, they need to be transported across the membrane by carrier proteins.
Large protein can pass into the cell by endocytosis. Endocytosis is a process by which the cell engulfs large molecules or particles. The cell membrane forms a pocket around the molecule or particle, and then the pocket pinches off to form an endocytic vesicle. The endocytic vesicle then fuses with a lysosome, where the molecule or particle is broken down.

How did the bombardment of Earth by solid particles affect its temperature
Answer:it affected it by being hot
Explanation:
snglekns
The bombardment of the earth by solid particles affects its temperature because the bombardments release heat and make the earth warmer, and due to this, the early earth was hotter.
What is the earth?The Earth is the planet in the solar system that moves around the sun, and it has living plants and animals along with non-living substances such as soil, air, water, etc. Most of the earth is covered with water and the earth has various populations, biomes, and biodiversities, and all of this biodiversity is due to changes in climate and geography, which result in the presence of various animals.

The fence around the school's garden is 22.6 m. If the garden is 7.5 m long, how wide is the garden? *
Answer:
Explanation:
22.6 is the perimeter because the question has the key words "fence" and "around" that let us know.
Perimeter equation is L+L+W+W
We know 7.5 is the length (could also be the width, it doesn't matter the order)
The length appears two times, so lets plug it in-
22.6= 7.5+7.5+W+W , Now you want to combine the like terms so.. 7.5+7.5=15
22.6= 15+W+W
Now subtract the 15 from 22.6
7.6= W+W , there are two W's left so divide 7.6 by 2
7.6/2= 3.8
It is 3.8 m wide

Why do you have to determine the total magnification when observing a specimen under the compound microscope?
Answer:
To clearly see specimens under the microscope, and to be able to see two separate objects that are close together.
Explanation:
A microscope is a tool that makes an object look bigger so that the person who is looking at it can see it. It's important to use a microscope because cells are usually too small to see with the naked eye. In addition to magnification, microscopes also have resolution, which is the ability to see two objects that are close together as separate. A microscope needs both magnification and resolution to be able to clearly see specimens under the microscope. When the light microscope bends light at the specimen, it gives the viewer a clear picture of the specimen. A series of lenses do this.

Answer:
because when oxygen atom bonds with two hydrogen atoms they form water
Explanation:
A water molecule is formed by covalent bonds between an oxygen atom and two hydrogen atoms. The bond between hydrogen and oxygen involves unequal sharing of electron – it is a polar covalent bond. This is because the nucleus of the oxygen atom is more attractive to electrons than the nuclei of the hydrogen atom.

what is the process that breaks down nucleic acids into nucleotides
a. dehydration synthesis
b. synthesis
c. polymerization
d. hydrolysis
please help ty
Answer:
D. Hydrolysis
Explanation:
Dehydration synthesis reactions build molecules up and generally require energy, while hydrolysis reactions break molecules down and generally release energy. Carbohydrates, proteins, and nucleic acids are built up and broken down via these types of reactions, although the monomers involved are different in each case.
I hope this helps have a great day :)
The process that breaks down nucleic acids into nucleotides is hydrolysis. The correct option is d.
What is hydrolysis?Any chemical reaction in which a water molecule breaks one or more chemical bonds is known as hydrolysis.
When water is the nucleophile, the phrase is used generically to refer to substitution, elimination, and solvation processes.
Nucleo depolymerase is another name for nuclease. By cleaving the phosphodiester bond that connects the nucleotides in the nucleic acids, the nucleic acid is broken down into nucleotides.
Either an enzyme or a non-enzyme can cleave the nucleic acid chain. Since the initial step in the alkaline hydrolysis of a polynucleotide is the transfer of the bond from C5' of the subsequent nucleotide to C2' of the same nucleotide, a 2'-OH group is necessary.
Thus, the correct option is d.
