Answer:

North American Countries

In North America, the nations of the United States and Canada own land areas in the Arctic. The only U.S. state containing land within the Arctic Circle is Alaska. In contrast, Canada’s polar regions are quite vast, encompassing about two-fifths of its entire land mass and two-thirds of its total maritime coastline. The historic residents of North America’s polar zones are the Inuits, who have made their livelihoods hunting and fishing in the harsh climate for more than 9,000 years, though many modernly work in oil fields and support villages.

European Countries

The exclusively European nations possessing land north of the Arctic Circle are Norway, Sweden, Finland, Iceland and Denmark. Although Denmark proper doesn’t lie within the polar zone, its largest self-governing overseas administrative division -- Greenland -- does. In addition to a portion of the Norwegian mainland, Norway’s Arctic territories also include the islands of Svalbard and Jan Mayen. Vikings hailing from Norway were the European polar region’s first explorers, establishing a permanent settlement on Iceland in the ninth century and a long-lived settlement in Greenland in the 10th century.

An organism has a metabolic pathway that is controlled by an inducer through negative regulation. When this organism is grown in
beks73 [17]

Answer:

The inducer will combines with the repressor and inactivates the pathway.

Explanation:

Inducer is a term in Molecular Biology, which represent a molecule or substance that has the capability to activate the transcription of a gene, where by it joins with and then inactivates a genetic repressor.

In other words, the inducer binds with the repressor in order to prevent the RNA polymerase to combine to the DNA, and chemically produce mRNA, this is done by repressor proteins combining with the DNA strand.

Inducer specifically makes repressor to change shapes, which will make it not combine with the DNA, and therefore, allow formation of transcription, such that expression of gene will eventually occur.

What is difference between Microtubules and Microflaments?
Nina [5.8K]

Microfilaments

Microfilaments are fine, thread-like protein fibers, 3-6 nm in diameter. They are composed predominantly of a contractile protein called actin, which is the most abundant cellular protein. Microfilaments' association with the protein myosin is responsible for muscle contraction. Microfilaments can also carry out cellular movements including gliding, contraction, and cytokinesis.

Microtubules

Microtubules are cylindrical tubes, 20-25 nm in diameter. They are composed of subunits of the protein tubulin--these subunits are termed alpha and beta. Microtubules act as a scaffold to determine cell shape, and provide a set of "tracks" for cell organelles and vesicles to move on. Microtubules also form the spindle fibers for separating chromosomes during mitosis. When arranged in geometric patterns inside flagella and cilia, they are used for locomotion.

Hope this helps :)

HELP PLEASE WILL GIVE BRAINLIEST!!!
levacccp [35]

1) 5% of saturated fat in one serving

2) 2 grams of dietary fibre

3) 750 calories

4) 9%

5) no

Explanation:

From the chart it is given that 1 serving gives 250 calories of energy while 1 container has 3 servings.

The dietary fibre in 250 calorie serving is 2 grams so on consuming 1 serving you get 2 grams of dietary fibre. It provides bulk to the roughage.

The entire container will give

3*250

= 750 calories in entire container.

If entire container consumed then ( 2grams amounts to 3%)

so three servings, 3*3

      = 9%

No vitamin C is found in the serving.
