BIOLOGY ASSIGNMENT TITLE
Binary fission produces daughter cells that do not have an exact replica of parental DNA is not a true statement about binary fission.
option A.
What is binary fission?Binary fission is a method of asexual reproduction used by bacteria and archaea, in which a single cell divides into two identical daughter cells. During binary fission, the cell's DNA replicates, and the two copies move to opposite ends of the cell.
The cell then elongates and eventually divides into two identical daughter cells, each with an exact replica of the parental DNA. Binary fission is a rapid and efficient way for bacteria and archaea to reproduce and is responsible for the exponential growth of bacterial populations.
Thus, in binary fission, the parental DNA replicates, and the two copies separate to opposite ends of the cell. The cell then elongates and eventually splits into two identical daughter cells, each with an exact replica of the parental DNA. Therefore, option A is not true.

Explanation:
Describe what is meant by the selective permeability of the plasma membrane. Why can't larger polar molecules and ions freely cross a lipid bilayer? (Consider the chemistry of the phospholipids as well as the physical barrier).
Answer:
The plasma membrane is a selectively permeable barrier that separates the cell from its environment. This means that while some substances can pass through the membrane freely, others cannot. The selective permeability of the plasma membrane is due to its structure, which is composed of a lipid bilayer with hydrophilic heads facing outward and hydrophobic tails facing inward.
The hydrophilic heads of the phospholipids are attracted to water, while the hydrophobic tails repel it. This creates a barrier that is impermeable to water-soluble substances, such as ions and polar molecules. Additionally, the phospholipid bilayer is relatively impermeable to larger nonpolar molecules, such as proteins and carbohydrates.
Small nonpolar molecules, such as oxygen and carbon dioxide, can diffuse easily across the plasma membrane due to their ability to dissolve in the hydrophobic interior of the lipid bilayer. However, larger polar molecules, such as glucose and amino acids, cannot pass freely through the membrane.
One reason for this is that the polar molecules are attracted to water, which is repelled by the hydrophobic tails of the phospholipids. This makes it difficult for the polar molecules to cross the lipid bilayer without assistance from specialized transport proteins, such as channels and carriers.
Furthermore, ions have an electrical charge that makes it difficult for them to cross the hydrophobic lipid bilayer. The charged particles are repelled by the hydrophobic tails of the phospholipids, and therefore, cannot pass through the membrane freely.
In summary, the selective permeability of the plasma membrane is due to the chemistry of the phospholipids, which create a hydrophobic barrier that is impermeable to water-soluble substances. Larger polar molecules and ions cannot freely cross the lipid bilayer because they are attracted to water and have an electrical charge that repels them from the hydrophobic interior of the membrane.

A. What are three types of change that occur in the process of metamorphism? (3 points)
B. What happens to the rock structure during each of type of change? (6 points)
Answer:
A. Three types of changes that occur in the process of metamorphism are: 1. Pressure: When rocks are subjected to high pressure, they can change form without melting. This is called pressure metamorphism. 2. Temperature: If rocks are heated to high temperatures, they can change form without melting. This is called thermal metamorphism. 3. Chemical changes: Rocks can undergo chemical changes due to the introduction of fluids. This is called hydrothermal metamorphism. B. During pressure metamorphism, the rock structure changes due to the pressure, causing minerals to reorient themselves and form new minerals. During thermal metamorphism, the rock structure changes due to the heat, causing minerals to recrystallize and form new minerals. During hydrothermal metamorphism, the rock structure changes due to the introduction of fluids, which can cause new minerals to form and old minerals to dissolve.
explain how a bacterial cell can be genetically modified to glow in the dark.
The process of genetically modifying a bacterial cell to produce a glowing effect is called genetic transformation.
How does genetic transformation work?This is usually achieved through the insertion of a foreign piece of DNA, such as a gene for bioluminescence, into the bacterial cell's genetic material.
One common method for introducing new DNA into bacterial cells is through a process called electroporation. This involves briefly exposing the cells to an electrical pulse, which temporarily disrupts the cell membrane and allows the foreign DNA to enter.
Once the foreign DNA has been incorporated into the bacterial cell's genome, it can be expressed and translated into a protein that produces the glowing effect. In the case of bioluminescence, the gene for the bioluminescent protein is expressed, leading to the production of the protein that emits light.

How does a fever disrupt homeostasis? Use the terms stimulus, control center, set point, receptors, effectors, and imbalance in your answer. Please underline or highlight these words in your response.
Homeostasis Infected bacteria and viruses that are adapted to replicate at your normal homeostatic body temperature range may be hindered by the elevated temperature.
As a result, your immune cells may have a chance to eliminate the bacteria before they spread and reproduce quickly inside the body. The Our body's temperature is recorded by the hypothalamus, which compares it to the ambient temperature of about 37 degrees Celsius. If our body temperature drops too low, the hypothalamus makes sure that the body generates and maintains heat.
Homeostasis with variable set points can be seen in many different situations. Fever, in which the set point for core body temperature increases and is sustained at a higher level, is one of the most noticeable
Your sweat glands are signalled to produce perspiration in order to cool you off when your hypothalamus determines that you are too hot.When the hypothalamus senses that you are too cold, it sends signals to your muscles that drive you to shiver and produce heat.

which statement describes a characteristic of independent assortment
The correct response is D. Independent assortment does not depend on the arrangement of tetrads during meiosis to determine which chromosomes daughter cells get.
What is chromosome?Chromosomes are components of a cell's nucleus that house the genetic material, or genes, that make up an organism. DNA (deoxyribonucleic acid) and proteins make up chromosomes, which are in charge of passing genetic information from one generation to the next during cell division.
Genetic differences between siblings originate from various chromosomal combinations from one parent. Independent assortment, which occurs during meiosis, is the random division and distribution of homologous chromosomes. It produces genetically varied gametes with various arrangements of maternal and paternal chromosomes. This indicates that the chances of each gamete obtaining either the maternal or paternal copy of a specific chromosome are equal.
This indicates that the chances of each gamete obtaining either the maternal or paternal copy of a specific chromosome are equal. Siblings may therefore have various chromosomal combinations that they inherit from their parents, resulting in genetic diversity.
