C! It only kills the moth larvae and doesn’t hurt other harmless insects

Healthy human lungs look pink and spongy from the outside. The left lung is a little smaller than the right lung to make room for the heart. The lungs and heart are both protected by the rib cage. In the lungs, each main bronchus branches off into many smaller bronchi. The bronchi become smaller and smaller, and the smallest bronchi are called bronchioles. There are about 30,000 bronchioles in each lung, each about the same thickness as a strand of hair. The inhaled air eventually ends up in tiny air sacs called alveoli at the end of each bronchiole. There are about 300 million alveoli in each lung. They are covered with capillaries, tiny blood vessels that are only one cell thick. Oxygen travels from the alveoli through the capillaries to the bloodstream, heart and other cells.

Which of these best represents the progression of bronchi, bronchioles and alveoli in the lungs?

A
tree trunks that become smaller branches and twigs

B
a tight flower bud that has opened into a full bloom

C

How do different climate zones respond to severe weather?
What challenges does each climate zone face?
How can that climate zone be best prepared for severe weather?
Which climate zone is the safest to live in? Why?

what was the aztecs economy like What is the answer to this question I need help asap, i will report you if you dont answer the question correctly, steal points, or try to scam me. (these are all the points i have left)Read the following text from the play Julius Caesar:FLAVIUS But wherefore art not in thy shop today?Why dost thou lead these men about the streets?Second Commoner Truly, sir, to wear out their shoes, to get myselfinto more work. But, indeed, sir, we make holiday,to see Caesar and to rejoice in his triumph.MARULLUS Wherefore rejoice? What conquest brings he home?What tributaries follow him to Rome,To grace in captive bonds his chariot-wheels?You blocks, you stones, you worse than senseless things!O you hard hearts, you cruel men of Rome,Knew you not Pompey? Many a time and oftHave you climb'd up to walls and battlements,To towers and windows, yea, to chimney-tops,Your infants in your arms, and there have satThe livelong day, with patient expectation,To see great Pompey pass the streets of Rome:And when you saw his chariot but appear,Have you not made an universal shout,That Tiber trembled underneath her banks,To hear the replication of your soundsMade in her concave shores?And do you now put on your best attire?And do you now cull out a holiday?And do you now strew flowers in his wayThat comes in triumph over Pompey's blood? Be gone!Run to your houses, fall upon your knees,Pray to the gods to intermit the plagueThat needs must light on this ingratitude.Once you have read the text, examine the following painting titled Caesar Victorious:Ceasar Victorious, Andrea Andreani, 1598 (1599), The painting has a deliberately crowded, celebratory feeling. There is the sense of action, as it depicts the triumphant return of Julius Caesar to Rome. Caesar, dressed in formal robes, is positioned to the right of the painting on his golden chariot riding through the streets with the Arch of Constantine in the background against blue skies and an adoring attendant in the foreground on the left carrying the victory banner that reads 'VENI VIDI VICI' (translation: I came, I saw, I conquered). The left side only is framed by an elaborate faux column, while the others are left simple. In the traditional image, Caesar sits high up on the chariot behind his white horse. He is holding a staff and a large feather, while an angel is depicted behind him placing a headdress upon his head. People mill around between the cart and the Arch watching the procession while cherubs offer branches of victorious recognition in the foreground. Public DomainIn at least two to three paragraphs, write an essay where you analyze the tone the character Marullus uses to express his interpretation of Caesar's return. Then explain how this is similar or different from the interpretation the painter has depicted? Use specific examples to support your observations. Use proper spelling and grammar.
