You have a piece of DNA containing the gene for green fluorescent protein (gfp) and the pBAD promoter. This DNA fragment has been cleaved with BamHI and HindIII and can be inserted into either the pKAN-R plasmid or the pARA plasmid. Which plasmid would you choose to use as the plasmid vector to express gfp protein in bacterial cells
Answer:
pARA plasmid
Explanation:
Plasmids are natural circular DNA samples found in bacteria cells. There are two types of plasmids founds in bacteria cells namely; pARA and pKAN-R.
The pKAN would not be maintained in the cell during replication but the pARA plasmid would and when the DNA fragment is inserted, the pARA would serve as a catalyst for the gfp protein.
uncontrolled cell division can lead to the formation of masses of cells that can remain in place called ____ tumors or ones that can move called ___ tumors
Answer:
Uncontrolled cell division can lead to the formation of masses of cells that can remain in a place called primary tumors or ones that can move called metastatic tumors.
Explanation:
The term primary tumor refers to the original tumor, a place where the tumor first appeared.
Metastatic tumors are tumors that appear in other organs and originate from the primary tumor. Tumor cells can break away from the primary tumor and travel to other locations in the body through the blood or lymph system and form new tumors. This is how metastatic tumors appear.
For example, a brain tumor is a primary tumor if it first appeared in the brain. A metastatic brain tumor is a tumor that appeared in another organ and then spread to the brain.

"Which areas or regions of the world, if any, are currently showing the greatest effects of climate change?"
Answer:
Climate change and land-use changes are expected to increase the rates of species extinction.
Explanation:
Eutrophication occurs when excess nutrients are supplied to a region, leading to an algae bloom and ultimately
A) ocean deoxygenation
B) coral bleaching
c) ocean acidification
D) overfishing
Answer:
A) ocean deoxygenation
Explanation:
Eutrophication (eutrophication) begins when fertilizers (usually washed away by rain) reach the water from fields and other agroecosystems. Fertilizers are rich in phosphates and nitrates, which are otherwise a limiting factor for the flourishing of life in water.
With an excess of these salts, plants, especially algae, often begin to flourish. Then the number of dead algae increases, which are then decomposed by saprophytes, consuming oxygen. Thus, the concentration of oxygen in the water decreases, and thus there is suffocation and mass death of aquatic organisms that consume oxygen in the process of respiration.
acid rain is an example of ______.
chemical weathering.............

What are researchers doing to great whites in hopes of being able to learn more about their behavior patterns?
Answer:
tagging the sharks
Explanation:
To learn their behavioral patterns researchers are tagging the sharks. Doing so allows the researchers to track their movements individually and gather data as to how they move, where they migrate to, how many migrate together, etc. All this information is extremely valuable and when pieced together can shed light on why they have certain behavioral patterns or traits.

Explanation:
This is the backbone of the DNA strand.
a. sugar-phosphate groups
b. nucleic acids
c. diploids
d. ribonucleic acids
e. amino acids
Answer: B. nucleic acids.
Explanation: A sugar-phosphate backbone (alternating grey-dark grey) joins together nucleotides in a DNA sequence. The sugar-phosphate backbone forms the structural framework of nucleic acids, including DNA and RNA. This backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.

18. During meiosis, homologous chromosomes exchange genetic material. This exchange of
genetic material -
A. increases the genetic variation
B. reduces the diploid number to the haploid number
C. increases the haploid
number to the diploid number
D. reduces the probability of mutations
A. increases the genetic variation
that's why individuals don't look like their partents. This process is called crossing-over
During meiosis, homologous chromosomes exchange genetic material. This exchange of genetic material - A. increases the genetic variation.
During meiosis, homologous chromosomes may exchange genetic material during a process called "crossing over."
Crossing over takes place during the pachytene stage of Prophase I of Meiosis I where the non-sister chromatids of homologous chromosomes exchange genetic materialthis results in recombination of the genetic material and creates a new genetic combination. This results in variations, which can be beneficial to the offspring providing a better survival advantage.So, the correct answer is Crossing over produces new combinations of genes on alleles, increasing genetic variation.

What evidence do we have of Neanderthal intelligence?
Answer:
What's more, genetic evidence has shown that modern humans mated with Neanderthals before these individuals disappeared about 40,000 years ago. Many of us today still have 1 to 2 percent Neanderthal DNA, findings that suggest that modern humans who encountered these individuals saw them as people, too.
When people fall ill, their immune system fights the disease and tries to restore the person to good health. Which disease is known to attack the human immune system leaving the body susceptible to various kinds of infection?A. Chicken PoxB. PneumoniaC. TuberculosisD. AID
Answer:
D. Aids
Explanation:
Aids is one of the most deadliest diseases in the world. When you contract aids, it's designed to infect the cells that try to destroy it, it's a whole zombie apocalypse in your body and you don't even know it.
It attacks and weakens the immune system, and our immune system defends our bodies against infections, but HIV is extremely strong and it over powers the system, I'm not sure if there's an immune system strong enough to fight HIV or aids.
Explain how iron, in the diet of humans, is used in the body.
The human body needs iron to make the oxygen-carrying proteins hemoglobin and myoglobin. Hemoglobin is found in red blood cells. Myoglobin is found in muscles
2. a) Describe the ways that energy is converted between forms during the light reactions. 2. a) Describe the ways that energy is converted between forms during the light reactions.
Answer:
Light energy is converted to chemical energy.
Please find the explanation below
Explanation:
Photosynthesis is a unique process that occurs in the cells of green plants and other autotrophic organisms. It is the process whereby they synthesize their food in form of carbohydrates (sugars). The photosynthetic process takes place in two stages namely: light dependent reaction and light-independent reactions.
The light dependent reaction or simply light reaction is the stage where light energy from the sun is harnessed by a pigment called CHLOROPHYLL and used to produce ATP needed to build glucose molecules in the next stage. Hence, via this process, the LIGHT ENERGY from the sun is converted to CHEMICAL ENERGY in ATP.

A student looks at his cell under a microscope which of the following observations would indicate the cell is from a plant rather than an animal
Answer:
Chloroplasts in the cytoplasm of the cell
Explanation:
The options you were given are the following:
nucleus is located inside of the cell numerous cilia on the outside of the cell chloroplasts in the cytoplasm of the cell a thin membrane around the edge of the cellThe organelles that would indicate that the observed cell belongs to a plant rather than an animal are chloroplasts. Chloroplasts are organelles that conduct photosynthesis - a process in which plants (and some other organisms that possess chloroplasts) get food. In this process, with the help of sunlight, plants transform carbon dioxide, water, and minerals into oxygen, which is released into the atmosphere, and glucose, which they feed on.
Both animal and plant cells have a cell membrane and the nucleus located inside of them.
The cilia are usually found in animal cells.
This is why the third option is the correct one.
