Answer and Explanation: GFP gene is a gene that encodes a green fluorescent protein. When bacteria and plasmid are combined, the gene is expressed as observed by the results: plasmid with GFP gene produces colonies with green color; while plasmid without GFP produces white colonies.
Ampicillin is an antibiotic, i.e., bacteria is naturally suscetiple to it.
Plasmid has an ampicillin resistant gene. This is demonstrated in the experiment: when there is plasmid, the gene can be expressed, allowing colonies to grow. But, when bacteria is not combined with plasmid, it is not resistant to the antibiotic, so no colonies are formed.

What occurs in an updraft?
A. Cool air from the surface spins in a circle.
B. Cool air from mountains causes high winds.
C. Warm air high in the atmosphere sinks.
D. Warm air from the surface rises.
Answer:
D. Warm air from the south rises.
Explanation:
Updraft occurs when the warm air from the surface rises.
What is Updraft?Updrafts occur when the warm air rises to the level when the process of condensation begins and precipitation starts to develop.
In a mature storm, updrafts are present alongside downdrafts that caused by cooling and falling of precipitation so we can conclude that updraft occurs when the warm air from the surface rises.

A landform being broken apart is weathering erosion or deposition? and is a glacier forming from an accumulation of ice and snow is weathering and erosion or deposition? please help fast
Answer:
A landform being broken apart is WEATHERING.
A glacier forming from an accumulation of ice and snow is DEPOSITION
Explanation:
This is because weathering is the process where rocks or landforms are broken down into smaller pieces sometimes form soul through the activity of an agent which could be wind, water, ice, gravity e.t.c.
While Deposition is the accumulation of segments of particles in a new location forming another shape after it has been wash away(erosion) into that new location by water, ice, wind, gravity e.t.c.
Answer:
A landform being broken apart is weathering.
A glacier forming from an accumulation of ice and snow is deposition
Explanation:
A scientist believes that she has found a new life form. Which of the following conditions is NOT considered essential in determining whether the putative new life form exhibits/shows the properties of life?
a. It appears to have cells when viewed under a microscope
b. It seems to react to being touched
c. It possesses a purposeful anatomical structure that differs from one another
d. It's body is bilaterally symmetrical
Answer: It's body is bilaterally symmetrical
Explanation:
The option that is not considered essential in determining whether the putative new life form shows the properties of life is that its body is bilaterally symmetrical.
The fact that the creature has cells signifies that it has life, reaction towards touch is also another factor that shows its has life.
We should note that its body shape doesn't signify I it has life or not. Therefore, the answer is D.
How many chromosomes are found in the common strawberry found in the grocery stores?
Answer:
In total, they have 56 chromosomes
Explanation:
Unlike Humans which has two copies of 23 chromosomes (in total 46) common strawberries have 8 copies of 7 chromosomes hence why they have a total of 56 chromosomes.
Case study A man and woman are deciding whether to have a child. The genotype of the man includes a recessive allele for an inherited
disease. The genotype of the woman does not include this allele. Both parents have a normal phenotype. Could the child inherit the
disease? Explain your reasoning. This is a great place to use your CER (Claim, Evidence, Reasoning) skills!
I
+
Explanation: When both parents are carriers for a recessive disorder, each child has a 1 in 4 (25 percent) chance of inheriting the two changed gene copies. A child who inherits two changed gene copies will be “affected,” meaning the child has the disorder.
Hope this helps! :)

Picture yourself hiking in a narrow canyon in Utah. The canyon is dry and it hasn’t rained for weeks. You see some thunderhead clouds in the sky, but not one drop of rain all day.
Nevertheless, a small rush of water starts to run through the canyon, turning it into a creek. There must have been a heavy rainfall somewhere nearby. Water runs down the sides of the canyon, forming little waterfalls. You realize that there could be a flash flood coming! You turn quickly up a side trail to higher ground before you are washed down the canyon.
What are the stimulus and response in this scenario?
A. The stimulus is the rain clouds and the response is the water in the canyon.
B. The stimulus is the appearance of water in the canyon and the response is moving to higher ground.
C. The stimulus is water running down the canyon walls and the response is little waterfalls forming.
D. The stimulus is the rain somewhere else and the response is you realize that there could be a flash flood.

You are solving a density problem, where density = mass/volume. Your volume of liquid is 2.1 milliliters. Your mass of the liquid is 2.811 grams. What is the density of the liquid using the correct number of sig figs?
Answer:
Density = 1.3386kg/m³
Explanation:
Given the following data;
Volume = 2.1 millimeters to meters = 2.1/1000 = 0.0021 meters
Mass = 2.811 grams to kilograms = 2.811/1000 = 0.002811 kilograms
To find the density;
Density can be defined as mass all over the volume of an object.
Simply stated, density is mass per unit volume of an object.
Mathematically, density is given by the equation;
[tex]Density = \frac{mass}{volume}[/tex]
Substituting into the equation, we have;
[tex] Density = \frac {0.002811}{0.0021} [/tex]
Density = 1.3386kg/m³

How are bacteria different from viruses?
A. Bacteria are multicellular.
B. Bacteria are eukaryotes.
C. Bacteria are not killed by antibiotics.
D. Bacteria can replicate themselves without help from a living cell.
Answer:
d
Explanation:
bacteria can replicate themselves without help from a living cell.
Bacteria are capable of self-replication without the assistance of a live cell. So, the correct option is D.
What is Bacteria?Bacteria are ubiquitous, generally free-living creatures that are frequently made up of one biological cell. They make up a significant portion of the prokaryotic microbial kingdom. Usually a few micrometres in length, bacteria were among the earliest life forms to appear on Earth, and are ubiquitous in most of its environments.
Bacteria lack a nucleus bound to the membrane and other internal components and are consequently placed within the group of unicellular life-forms called prokaryotes. Prokaryotes have dominated life on Earth for at least three-quarters of its existence and have adapted to nearly all of the planet's biological niches. Bacteria are capable of self-replication without the assistance of a live cell.
Therefore, the correct option is D.

Describe the scientific theory of cells (cell theory) and relate the history of its discovery to the process of science.
Answer:
The cell theory states that all living organisms are made up of cells and each cell is the fundamental and functional unit of the living organism. The last point of the theory is that each cell is produced by a pre-existing cell.
The cell discovery was made by Robert Hooke with the help of the compact microscope was made by him. He observed the cell wall of the cell in cork and after him, many other scientists proved the presence of cells and presented evidence of the cell theory.
