Scientists have noted patterns in the Earth's seafloor structures. For example, volcanic ridges are typically located in the center of the oceans, and trenches are typically located along the edges of continents. In addition, seafloor rocks found at the trenches are usually older than seafloor rocks found at the volcanic ridges. Which explanation of the past movement of the Earth's plates is best supported by this information? A. The continents were pushed apart when new crust formed in the center of the ocean and pushed older crust away from the volcanic ridges. B. The continents were separated when new crust that formed at the edges of the continents pushed older crust towards the center of the ocean. C. The formation of new crust at the trenches widened the seafloor and pushed the edges of the continents away from one another. D. The Earth's crust formed at the trenches and moved towards the volcanic ridges to make room for newer crust, pushing the continents apart.

Answers

Answer 1

Answer:

A. The continents were pushed apart when new crust formed in the center of the ocean and pushed older crust away from the volcanic ridges.

Explanation:

The crust is divided into many plates that move over the mantle. Nowadays, there are six different bigger plates and twelve that are smaller. These plates are limited by three types of ridges or borders that differ in the movement they produce.

Boundaries types:

I. Divergent

II. Convergent

III. Transforming

In divergent boundaries, a new crust is created by the rising molten materials coming from the mantle. Two plates separate, and the stream of hot material creates a new seabed between them. It occurs an expansion of the sea bottom. As old plates get separated, the new and young crust instantaneously gets formed. The emerging mantle occupies the space left by the separation of the two plates. This process occurs along with an underwater mountain range, known as the mid-oceanic ridge or divergent ridge. An example of this is the ridge located in the middle of the Atlantic Ocean, extending from Greenlander to the southernmost point of South America.

Answers

Answer:

One increase in population and the other decrease.

Explanation:

The population of the rats having little larger teeth and longer claws increases as compared to those rats having small teeth and shorter claws because the rats can escape from their predators and survive in that environmental conditions. The population of rats  having small teeth and shorter claws extinct in the end due to no reproduction and preyed by the predators and dominated by the population of the rats having little larger teeth and longer claws due to their features.

The main role of the ________ is to increase the binding ability of RNA polymerase to the lac operon promoter region.

Answers

Answer:

catabolite activator protein (CAP)

Explanation:

Catabolite activator protein (CAP) is a homodimeric transcriptional activator required for transcription initiation of catabolite-sensitive genes in Escherichia coli. CAP contains a ligand-binding domain at its N-terminus and a DNA-binding domain at its C-terminus. CAP activates transcription by binding at target DNA sites on promoter sequences, thereby enhancing the ability of the RNA polymerase to bind and initiate transcription. CAP binds cyclic AMP (cAMP) to increase CAP’s affinity to DNA and thus activates the transcription of genes for catabolism, such as the lactose (lac) operon genes (the lac operon is a set of genes that encode for enzymes taking part in lactose metabolism).


describe how and where each type
weathering, erosion, or deposition occurs

Answers

weathering: Weathering occurs in situ (on site, with little or no movement), and should not be confused with erosion, which involves the transport of rocks and minerals by agents such as water, ice, snow, wind, waves and gravity. Weathering processes are divided into physical and chemical weathering.

erosion: Erosion happens when rocks and sediments are picked up and moved to another place by ice, water, wind or gravity. Mechanical weathering physically breaks up rock. One example is called frost action or frost shattering. ... The sediment is dropped, or deposited, in landforms.

deposition: Deposition is the processes where material being transported by a river is deposited. Deposition occurs when a river loses energy. This can be when a river enters a shallow area (this coud be when it floods and comes into contact with the flood plain) or towards its mouth where it meets another body of water.

Villi are surrounded with cells that help in the absorption of nutrients from the food that passes through it.

What happens if Rainsford refuses to play the game?

A.
he is set free

B.
he must swim to a passing boat

C.
Ivan gets him

D.
he lives with Zaroff forever

Answers

Answer:

C.  Ivan gets him.

Explanation:

Richard Connell's "The Most Dangerous Game" is about Sanger Rainsford, a famous hunter who cared less about his prey. But then the tables turned and he became hunted instead of being the hunter, thereby presenting the theme of civilization and savagery, conscience, etc.

After Rainsford reached "Ship Trap Island", he discovered that there lived someone, Colonel Zaroff. But soon, he became aware of the "game" that the colonel likes to hunt. Refusing to be a part of the hunt, he was offered to be either the prey (which leaves him a choice of being free if he survives 3 days being hunted) or be killed anyway by Ivan, the Cossack.

Thus, the correct answer is option C.

Protein digestion begins in the ________; fat digestion begins in the ________. Stomach; small intestine Mouth; stomach Esophagus; stomach Small intestine; small intestine Small intestine; large intestine

Answers

Answer:

Protein digestion begins in the mouth

Fat digestion begins in the stomach

Once a protein supply reaches your stomach, hydrochloric acid and enzymes referred to as proteases spoil it down into smaller chains of amino acids. Amino acids are joined collectively through peptides, that are damaged through proteases.

Fat digestion starts offevolved withinside the stomach. Some of the byproducts of fats digestion may be immediately absorbed withinside the stomach. When the fats enters the small intestine, the gallbladder and pancreas secrete materials to in addition spoil down the fats.

What is digestion?

The approaches of digestion encompass six activities: ingestion, propulsion, mechanical or bodily digestion, chemical digestion, absorption, and defecation. The first of those approaches, ingestion, refers back to the access of meals into the alimentary canal thru the mouth.

Immediately following the arrival of the stimulus at the axon terminal there is a short period called the ________ period during which no muscle tension is observed while the neurotransmitter is being released by exocytosis, diffusing across the synaptic cleft, and binding to its receptor to activate the muscle cell. relaxation latent contraction refractory

Answers

Answer:

Immediately following the arrival of the stimulus at the axon terminal there is a short period called the latent period.

Explanation:

When a stimulus reaches the terminal of an axon, a period known as the latent period begins. This period has a short duration and during it it is possible to observe the blockage of new stimuli in the nerve fiber. Thus, the new stimuli fail to trigger an impulse and no muscle tension to be observed.

While the latent period is not finished, the neurotransmitter is released through the action of exocytosis that moves until it gets access to the receptor capable of activating the muscle cell.

B) Uniform in the genetic information they contain

C) Separated by large sketches of repetitive DNA

D) Each void of typical protein-coding sequences of DNA

E) Void of introns.  

The correct answer is A.

Explanation:

The chromatin or substance that makes up the nuclei of cells and that results from the interaction of DNA with histonic and non-histonic proteins and RNA; it can present different degrees of packing or contraction. When chromosomes are stained with chemicals that bind to DNA, densely stained regions and less densely stained regions appear. Heterochromatin are segments of the chromosome that stain strongly and remain visible, practically, during the entire cell cycle. There are few genes in these regions and therefore low transcriptional activity. They are supercondensed regions. Euchromatin are segments of the chromosome that are not visible during telophase and interphase, only in metaphase. It corresponds to regions that are less compact and in which there is a higher gene density.
