Figure 1 represents a plasma membrane and molecules present on either side.
Part A: Describe the biological need for cells to be surrounded by a membrane that is selectively permeable for different materials.
Part B: Explain how the model shows selective permeability of the membrane to specific ions.
Part C: Describe the characteristics of the phospholipid bilayer that permit small hydrophobic lipid molecules to pass directly
Part D: Based on the model, explain whether the molecules shown crossing the membrane require energy to do so.
Answer:
A. Cell membrane is the outer layer of the cell that plays a role as the barrier between the internal and outer environment of the cell by regulating by allowing particles or substances to enter or exit the cell. It helps in maintaining the internal environment of the cell by allowing certain molecules to enter and stop other molecules.
B. Phospholipids bilayer is the part of the plasma membrane that makes it selective permeable. The plasma membrane does not allow ions with charges on the side of the molecules directly sodium, potassium, and many other ions are examples of this. Ions can enter or exit the cell with the help of the transporters or complexes.
C. There is hydrophilic-head and hydrophobic-tail present in the phospholipid bilayer in the structure of the cell membrane which makes it selectively permeable.
D. For active transport of molecules, the movement of molecules is always against the gradient which means movement from lower concentration to a region of higher concentration that requires energy (ATP).

Compare and contrast meiosis and mitosis. Show at least 5 sentences.
Mitosis and meiosis are two different kinds of cell cycle reproduction. They have many things in common together, such as being an asexual form of reproduction. Mitosis produces body cells, identical daughter cells that can grow an organism and replace old/dead cells. Meiosis on the other hand makes gametes; or reproductive cells. When mitosis happens, it goes through stage of the mitotic phase known as PMAT. PMAT stands for: prophase, metaphase, anaphase, and telophase; followed by cytokinesis. Meiosis on the other hand, goes through PMAT twice. After mitosis, the product is 2 identical cells, which are used to replace cells or to grow. After meiosis, 4 NON-identical cells are made, which contain HALF the set of chromosomes; hence being called a haploid cell.
Mitosis has only one round of cell division, while meiosis has two. Mitosis only occurs in body cells, while meiosis occurs in sex cells. Mitosis produces daughter cells, that are identical to the parent cell, while mitosis produces haploid/diploid cells that only have half of the normal number of chromosomes.
When a plant cell, such as one from a peony stem, is submerged in a very hypotonic solution, what is likely to occur? A. The cell will burst. B. Plasmolysis will shrink the interior. C. The cell will become flaccid. D. The cell membrane will lyse. E. The cell will become turgid.
Answer:
The answer is "Option E".
Explanation:
The turgid relates to cells or tissues swelling from its transport of moisture. Some types of cells would become turgid because of moisture absorption in several distinct species. Its vacuole is swelling or pressure created mostly on cell walls, that's why whenever a cell membrane is submerged inside an extremely isotonic solution including a cell of a peony stem, the cell becomes turgid.
An hypotonic solution is a solution when compared to others have a relatively low solute concentration.
So when a cell is placed in a hypotonic solution, the cell will become turgid. (option E).
When this cell is placed in a hypotonic solution, there is the flow of water across the solution and its surrounding environment. In a hypotonic solution, the solute concentration is lower than inside the cell. This flow continues until there is a net flow and equilibrium is achieved. The cell in this process gains volume and becomes entirely turgid swelling up.Learn more about turgidity: https://brainly.com/question/18740086

Explanation:
how can dna be used to help solve a crime
Answer:
dna can be used because no dna is the same unless there are identical twins. with using dna to solve a crime, you can test the dna to see if there are any similariteis or if they are exact. If there are similarities that means that someone related to that person is the person in charge of the crime. This is why dna evidence is one of the most important parts when looking at a crime scene because it is the most exact and precise way of convicting someone
Explanation:
Answer:
Each person’s DNA is unique.
Scientists use variable regions in DNA to create a DNA profile.
DNA samples can be taken from blood, bone, hair, or other body tissues and
products.
DNA from a crime scene can be compared to DNA from a suspect.
DNA typing can be used to solve old cases.

Explain that variation among offspring is a potential evolutionary advantage resulting from sexual reproduction.
S exual reproduction (Syngenesis) is that it results in variety in the offspring.
What is syngenesis reproduction?syngeneisis reproduction occurs when the sperm from the male parent fertilizes an egg from the female parent, producing an offspring that is genetically different from both parents.Within a community of organisms or a species, there is generally a lot of genetic variety. Because of their diversity, the species can adapt to different habitats, giving them a survival edge.During fertilization, the nuclei of a male and female gamete cell fuse together, resulting in syngenesis reproduction. Both parents' alleles are passed down to the children.Produces genetic variation in the offspring.The species can adapt to new environments due to variation, which gives them a survival advantage.Syngenesis reproduction has the potential to produce tremendous genetic variation in offspring. This variation is due to independent assortment and crossing-over during meiosis, and random union of gametes during fertilization.To know more about syngenesis reproduction here

Mutualistic fungus: lives around the roots of a tree and provide nutrients to the tree. Parasitic fungus: lives within the blood of another organism and cause disease. Saprophytic fungus: living in marsh environment and aids in biodegradation.
Fungus is a type of eukaryotic organism that belongs to the kingdom Fungi. Fungi are distinct from plants, animals, and bacteria, forming their own separate kingdom due to their unique characteristics and evolutionary history.
Mutualistic fungus establishes a symbiotic association with the roots of plants, forming structures called mycorrhizae. A parasitic fungus obtains nutrients from a living host organism, known as the host. They harm or exploit their hosts for their own survival and reproduction. A saprophytic fungus obtains its nutrients by decomposing dead organic matter.

Describe the effect that pilocarpine had on the heart and why it had this effect. How well did the results compare with your prediction?
Answer:
Pilocarpine can affect the heart since it shares the drug's binding site with the traditional receptors that it seeks to effect under treatments of xerestomia, dry eyes or Sjorgen's syndrome.
Explanation:
The effect is Parasympathomimetic in the exocrine glands, but these glands have the same receptors as the cardiac tissue, so you can see harmful cardiac side effects.
It increases adverse effects with ß-adrenergic antagonists, thus generating heart failure, and even kidney failure indirectly due to the possible risk of chronic heart failure.

Which of the following statements is true?
The dissolving power of water is very important for the transport of nutrients in blood.
The solid form of water is more dense than the liquid form, which is why ice floats.
Cohesion helps plants transport water from their roots to their leaves.
Surface tension is a measure of how much water molecules are attracted to other materials.
Answer:
The dissolving power of water is very important for the transport of nutrients in blood.
Explanation:
Water is known as the "universal solvent" because it can dissolve more substances than any other liquid. The dissolving power of water means that it can effectively transport nutrients, chemicals, and minerals. Plants rely on water to carry dissolved nutrients from the soil. Animals also benefit from water as a solvent.
