The answer would be:

Platelets stick to the damaged area of a blood vessel and help seal the break.

Platelets are blood cells that play a role in blood clot formation. It also helps with blood vessel repair. The process by which platelets stick to the damaged area of a blood vessel is called adhesion. When platelets stick to the damaged blood vessels they release chemical signals to attract more platelets to the site of injury

use the following paragraph to answer the question 1 throught 5 remember to include units in your answers
VLD [36.1K]

Answer:

Explanation:

1.       a) A topic sentence is a sentence that conveys the meaning and main message of a paragraph. Here is a topic sentence for this paragraph: An ocean beach is a great place for relaxing and enjoying nature. b) But the dog was still growling, afraid of the strange noise.

2.       There are many things to look for when proofreading, but these four would be the most important: spelling, grammar, punctuation, sentence structure. Spelling mistakes are common not only because people often don’t know how to properly write a word (for example, writing “they’re” instead of “there”), but because it is so easy to make a lapse when writing fast. Grammar errors include verb tense errors, subject-verb agreement errors, etc. Punctuation rules prescribe where to write a comma, dot, colon, semicolon, or any other punctuation mark. Finally, sentence structure is often a problem, even for the advanced speakers of a language.

3.       a) Cliché can be a word or a phrase, or even a whole sentence that has been used so frequently, by so many people, that it is devoid of meaning. It usually happens with expressions that have recently become widely accepted and popular. b) It’s such a pity you couldn’t see him on the battlefield. He was brave as a lion.

4.       Brainstorming is a prewriting practice that we use when we want to come up with as many ideas as possible. We jot down, in short phrases or bulleted points, everything that comes to our mind. The point is that every idea is worth having – so we don’t cast away either of them. Eventually, we will review those ideas, and pick those that seem to be the best. Another practice would be freewriting. We do it when we want to find an inspiration. It is different from brainstorming in that we don’t jot down ideas, but our stream of thoughts – however irrelevant or incongruent they might seem. It is a technique used by great writers such as James Joyce, or Virginia Woolf.

5.       d) When cleaning up a cluttered room, one has to do one thing at a time. First, I have to think hard and realize that I don’t really need half of those things that are scattered everywhere. Then, I try to collect all the garbage and put it in disposal bags. After that, it’s time to get rid of all the dust and cobweb. In comes the vacuum cleaner, and that is usually the end of it.

6.       e) Humanity is a few millennia old. But never did it change more quickly than in the past few decades, with the advancement of technology. It has brought an unprecedented revolution in communication. Things that had been unimaginable, such as talking to a friend at the other side of the globe, are now a normal, everyday thing. This privilege is cheap and affordable to the great majority of the people. However, technology has created a very paradoxical situation. By making the communication swifter, easier, and more efficient than ever, it has downgraded its quality and profundity. It has become utterly normal to see silent and isolated family members at a dinner table, who don’t talk to each other, but stare at their cell phones, talking to their virtual friends and sending them photos of the meals.

Which concept is not a part of the theory of evolution
garik1379 [7]

Answer:

I believe the options are:

1) Present day species developed from earlier species .

2) Some species die out when environmental changes occur .

3) Complex organism develop from simple organisms over time .

4) Change occurs according to the needs of an individual.

The answer is 4) Change occurs according to the needs of an individual.

Explanation:

Theory of Evolution:

  • By definition, evolution is the process of change in an individual's/organism's characteristics over time. Evolution occurs through mutations in the genetic information or DNA of an individual.
  • The theory of evolution states that all organisms change over time and are descendants of a single common ancestor. Species adapt to the changing environment by introducing variations in their DNA over millions of years. Harsh environment conditions eliminate organisms that cannot adapt to the changing environment and only the fittest survive. This is called natural selection.
  • This process, occurring over millions of years, results in the formation of an entirely new species.
  • The theory of evolution is contrary to the concept of Lamarckism or inheritance of acquired characters which states that characters that an organism acquires during its lifetime can be passed on to its offspring.

How are billions of genetically identical cells produced?
sammy [17]
Hi there!

The cells split, and, after a certain amount of time, the two identical replicas of the split cells split again into more cells. With energy, this process repeats until there are billions of trillions of cells.

Hope this helps!
