The diagram shows a plant cell before and after it is placed in a solution. After the cell is placed in the solution it changes shape.
Which table shows the initial concentration of solute in the cell and in the solution that would cause the cell to change shape,as shown in the diagram above?
A. Location-Solute Concentration
Inside cell-3%
Outside the cell-6%
B. Location-Solute Concentration
Inside cell-7%
Outside sidd-5%
C. Location-Solute Concentration
Inside cell-0%
Outside cell-0%
D. Location-Solute Concentration
Inside cell-12%
Outside celk-12%
Answers
Answer:
The answer is A.
Explanation:
The tonicity is hyper tonic solution. There is more water inside the cell and high solute concentration outside the cell. The water moves out of the cell and the cell shrinks. The plant will plasmolyze.
Here it is showing that the concentration inside the cell is 7% and outside is 5%. The correct option is B.
What is tonicity?Tonicity is a measure of the effective osmotic pressure gradient in chemical biology; the water potential of two solutions separated by a partially permeable cell membrane.
To describe whether a solution will cause water to move into or out of a cell, three terms are used which are hypertonic, hypotonic, and isotonic.
When a cell is immersed in a hypertonic solution, there is a net flow of water out of the cell, causing it to lose volume.
The direction and extent of osmotic flux are determined by the relative concentration of selective membrane-impermeable solutes across a cell membrane.
It is frequently used to describe the swelling-versus-shrinking response of cells immersed in a solution.
In the given image, the solvent concentration increases in the second image, which means its solute concentration was more and water concentration was less.
So, water translocated from outside the cell to inside.
Thus, the correct option is B.

3. PI of a protein is dependent on the number of acidic and basic amino acid residues in the protein.
Answers
Answer:
The study of proteins is important because all the genes in cellular DNA house the program or code for a unique protein structure.
Explanation:
Within the science parlance, pl is the short way to write Isoelectric Point. It is the pH (that is the acidity or basicity) of a solution at which the net charge of a protein becomes nil.
The surface, in most cases, is likely going to be negatively charged when the pH of that same solution is above the pl. When this occurs, molecules that have similar negative charges will tend to move away or be repelled.
It is useful to note that the structure of proteins comprises of 20 amino acids all of which are connected by peptide bonds.

Which of the karyotypes shown is from a normal female?
A
B
C
D
Answers
Answer: c
Explanation:
Females have two X chromosomes and males have an x and a Y chromosome. The Y chromosome is significantly shorter because it doesn’t carry as many genes. C is the only option that has two X chromosomes
The karyotype of a normal female is in diagram c. The correct option is c.
What is a karyotype?A karyotype is an individual's complete set of chromosomes. The phrase might refer to an image created in a lab showing a person's chromosomes separated from each individual cell and organized in numerical order.
If a person has a mutation, the karyotype can tell whether they are a man or a mulcher. This is so because a person's chromosomes are represented by a karyotype.
A 23-pair karyotype, one of which is made up of sex chromosomes that are XY for males and XX for women, is required for a person to be considered to be mutation-free.
Males have an x and a Y chromosome, while females have two X chromosomes. The Y chromosome is considerably smaller because it contains fewer genes. The only choice with two X chromosomes is C.
Therefore, the correct option is C.

C. The universal patterns of behavior and cognitive processes that are similar between humans and animals
d. The ways in which universal patterns of behavior and cognitive processes have evolved over time
Answers
Answer:
I believe the answer is D. The ways in which universal patterns or behavior and cognitive processes have evolved over time.
The primary focus of evolutionary psychology is the ways in which universal patterns of behavior and cognitive processes have evolved over time. The correct option is D.
What is evolutionary psychology?Evolutionary psychology is the study of behavior, thought, and emotion through the evolutionary biology lens.
According to evolutionary psychologists, all human behaviors are influenced by physical and psychological predispositions that helped human ancestors survive and reproduce.
Evolutionary psychologists believe that the human brain evolved in response to specific problems that early humans faced.
One central tenet of evolutionary psychology is that understanding modern human behavior requires considering the environment in which early humans evolved.
The study of how universal patterns of behavior and cognitive processes have evolved over time is the focus of evolutionary psychology.
Variations in cognition and behavior would affect an individual's ability to reproduce and pass on those genes to their offspring.
Thus, the correct option is D.
