Why do you think that some vaccines, such as the flu vaccine, need to be given every year?

Answers

Answer 1

Answer:

Because flu viruses evolve so quickly, last year's vaccine may not protect you from this year's viruses. New flu vaccines are released every year to keep up with rapidly adapting flu viruses.

Answer 2

Answer:

Because the virus/sickness would evolve and that vaccine might not protect you.

If a myostatin protein is not the right shape, it cannot fit correctly into a cells receptor true or false

Answers

This answer would be false

Explanation: Myostatin (also known as growth differentiation factor 8, abbreviated GDF8) is a myokine, a protein produced and released by myocytes that acts on muscle cells to inhibit muscle cell growth. In humans it is encoded by the MSTN gene.[6] Myostatin is a secreted growth differentiation factor that is a member of the TGF beta protein family.[7][8]

Therefore, if the myostatin protein is smaller than a microorganism it would be able to fit into the receptor.

A: two limbs and webbed toes.
B: a long tail that ate insects and lived in forests.
C: four limbs and a membrane consistent with gliding.
D: four fins that glided through the water.

Answers

Answer:

C

Explanation:

Four limbs and a membrane consistent with gliding are the structures found in ancestors of bats. Therefore, option (C) is correct

What is patagium?

A membrane called the patagium helps animals glide or fly. Bats, birds, dromaeosaurs, pterosaurs, gliding mammals, flying lizards, and flying frogs have the structure. The uropatagium (particularly in bats) or interfemoral membrane connects an animal's hind limbs.

Bats' wing skin extends from the abdomen to the tip of each digit, connecting the forelimb to the body. Bat patagiums have four parts:

Propatagium: neck-to-first-digit patagium.Dactylopatagium: digits.Plagiopatagium: between final digit and hindlimbs.Uropatagium: posterior flap between hindlimbs.

Therefore, option (C) is correct.

How can a change in genotype affect the phenotype?

Answers

Answer:

The genome in which a genotype is found can affect the expression of that genotype, and the environment can affect the phenotype. Genes can also be pleitropic when they affect more than one trait. The single base pair mutation that lead to sickle cell anemia is a classic example.

Answer: population

Explanation: An organism's genotype is the set of genes that it carries. ... However, since an organism's genotype generally affects its phenotype, the phenotypes that make up the population are also likely to change. For example, differences in the genotypes can produce different phenotypes.

What is the answer to 3/4= 6 I need help writing a two paragraphs assertion about a blind man from the passage the down below.He was plainly blind, for he tapped before him with a stick, and wore a great green shadeover his eyes and nose; and he was hunched, as if with age or weakness, and wore a huge oldtattered sea-cloak with a hood, that made him appear positively deformed. I never saw in my lifea more dreadful-looking figure. He stopped a little from the inn, and, raising his voice in an oddsing-song, addressed the air in front of him: Will any kind friend inform a poor blind man, who has lost the precious sight of his eyesin the gracious defence of his native country, England, and God bless King George! where or in what part of this country he may now be?You are at the Admiral Benbow, Black Hill Cove, my good man, said I.I hear a voice, said he a young voice. Will you give me your hand, my kind youngfriend, and lead me in?I held out my hand, and the horrible, soft-spoken, eyeless creature gripped it in a momentlike a vice. I was so much startled that I struggled to withdraw; but the blind man pulled me closeup to him with a single action of his arm.Now, boy, he said, take me in to the captain.Sir, said I, upon my word I dare not.Copyright TestingMom.com. All rights reserved worldwide. Use of this documentfor non-paying members of TestingMom.com is strictly prohibited.35Oh, he sneered, thats it! Take me in straight, or Ill break your arm.And he gave it, as he spoke, a wrench that made me cry out.Sir, said I, it is for yourself I mean. The captain is not what he used to be. He sits with adrawn cutlass. Another gentleman Come, now, march, interrupted he; and I never heard a voice so cruel, and cold, andugly as that blind mans. It cowed me more than the pain; and I began to obey him at once,walking straight in at the door and towards the parlour, where our sick old buccaneer was sitting,dazed with rum. The blind man clung close to me, holding me in one iron fist, and leaning almostmore of his weight on me than I could carry. Lead me straight up to him, and when Im in view,cry out, Heres a friend for you, Bill. If you dont, Ill do this; and with that he gave me a twitchthat I thought would have made me faint. Between this and that, I was so utterly terrified of theblind beggar that I forgot my terror of the captain, and as I opened the parlour door, cried outthe words he had ordered in a trembling voice.The poor captain raised his eyes, and at one look the rum went out of him, and left himstaring sober. The expression of his face was not so much of terror as of mortal sickness. Hemade a movement to rise, but I do not believe he had enough force left in his body.Now, Bill, sit where you are, said the beggar. If I cant see, I can hear a finger stirring.Business is business. Hold out your right hand. Boy, take his right hand by the wrist, and bring itnear to my right.We both obeyed him to the letter, and I saw him pass something from the hollow of thehand that held his stick into the palm of the captains, which closed upon it instantly.And now thats done, said the blind man; and at the words he suddenly left hold of me,and, with incredible accuracy and nimbleness, skipped out of the parlour and into the road,where, as I still stood motionless, I could hear his stick go tap-tap-tapping into the distance.It was some time before either I or the captain seemed to gather our senses; but atlength, and about at the same moment, I released his wrist, which I was still holding, and hedrew in his hand and looked sharply into the palm.Ten oclock! he cried. Six hours. Well do them yet; and he sprang to his feet.Even as he did so, he reeled, put his hand to his throat, stood swaying for a moment, andthen, with a peculiar sound, fell from his whole height face foremost to the floor.I ran to him at once, calling to my mother.

HELP PLEASE IM BEHIND IN SCHOOL(LINKS WILL BE REPORTED and other who comment random things)Read this section from **Chasing Lincoln's Killer* by James L. Swanson: "On the night of April 11, a torchlight parade of a few thousand people, with bands and banners, assembled on the semi-circular driveway in front of the Executive Mansion. This time Lincoln delivered a long speech, without gloating over the Union victory. He intended to prepare the people for the long task of rebuilding the South. When someone in the crowd shouted that he couldn't see the president Lincoln's son, Tad, volunteered to illuminate his father. When Lincoln dropped each page of his speech to the floor it was Tad who scooped them up." Which of these inferences about Booth is best supported by the text? 1:Being around postwar celebrations in Washington further fueled his rage toward Lincoln.2:He was emblematic of many actors and artists who strongly supported the Confederacy during the war. 3:He detested that the Lincolns were seeing a piece of theater that was as worthless as An American Cousin."4: It was completely accidental that he found himself in the same city as Lincoln at the end of the war.
