Respiration begins when air enters the mouth and nose. As air goes down the trachea, or windpipe, tiny hairs called cilia gently wave to keep dirt and mucus out. At the bottom of the trachea are two tubes called bronchi. One bronchus goes into the left lung, and the other goes into the right lung. When you inhale, the diaphragm muscle between the lungs and abdomen contracts, making room for the lungs to expand.
Which of these best describes how the lungs and diaphragm affect each other?
A
As the lungs expand, the diaphragm expands.
B
As the lungs expand, the diaphragm contracts.
C
As the lungs contract, the diaphragm contracts.
D
The lungs and diaphragm have no relationship.

Which of these is not a principle of natural selection?
A. Over time, the offspring of individuals with helpful variations make up more of a population and eventually become a separate species
B. Variations are passed to offspring
C. Differences, or variations, occur among individuals of a species
D. Adaptations happen in a start stop fashion
Answer:
D
Explanation:
adaptations are passed down in natural selection but it’s not in start stop fashion
Answer:
D
Explanation:
Adaptations occur, but they don't just stop. In virtually every population, you will have variation, and therefore, adaptations. They aren't going anywhere.

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?
Answer: 1. It just depends on what climate, for example Higher temperatures mean warmer seas, higher sea levels and more moisture evaporating into the atmosphere.
2. More frequent and intense drought, storms, heat waves, rising sea levels, melting glaciers and warming oceans can directly harm animals, destroy the places they live, and wreak havoc on people's livelihoods and communities.
3. Prepare by making sure that everything will stay in the same spot and check the forecast.
4. In North America because there is not a lot of very severe storms

what is the main function of the skin
Answer:
The skin has three main functions: Protection; Thermoregulation; Sensation.
Explanation:
protection from injury, infection and water loss, regulation of body temperature, elimination of wastes, gathering information and production of vitamin D.Provides a protective barrier against mechanical, thermal and physical injury and hazardous substances. Prevents loss of moisture. Reduces harmful effects of UV radiation. Acts as a sensory organ (touch, detects temperature).Absorption of UV rays, thermoregulation and protection for underlying tissues are all functions of skin.
What is the problem with using common names in classification?
A general phobia with unfamiliar latinized scientific nomenclature has proliferated the use of common or trivial names. These names, however, can vary with geographic region, language, or individual preference often and thus, can lead to misidentification or a delay in the proper identification of a toxic plant.
Answer:
The only problem of using common names is that we cannot deduce the features of a particular organism just by looking at its name.
Explanation:
The only problem of utilizing basic names is that we can't find the highlights of a specific organic entity just by seeing its name.
Why do roots always grow in a downward direction, no matter which way you turn the seed or seedling?
because roots weigh more than any other plant part
because the plant’s stem begins to grow, and it pushes the roots downward
because that is the direction that roots find necessary water and nutrients
because the root contains hormones that make it grow away from the sun

1. What idea you had for inveting the telephone?
- "I basiclly used a battery to provide current on the phone line and to control its strength by using carbon to vary the resistance".
2.Did you once wanted to give up while creating an artwork?
My only answer and quote im giving is this: “I have not failed 10,000 times – I've successfully found 10,000 ways that will not work.”
3.What inspired you?
-"I got my intrest by The Civil War it got me interested in invention."
4.How did you came up with the materials for making with your inventions?
"One night, after absent-mindedly rolling between my fingers a piece of lampblack, the material he used in his telephone receiver, I got the idea for switching to a carbonized filament".
5. So, Last question. Why you have to fail to succeed?
"Failure makes you better."
You have to find a way to find success through failure, and so you open yourself up to new ideas and new solutions to the same old problems. It may be difficult to cope with the setback at first, but eventually, mistakes will excite you.
Mitosis is only done by _____________________ cells and it makes ___________________________ cells.
Answer: Eukaryotic cells, daughter cells
Answer:
Eukaryotic Cells and Daughter Cells
Explanation:
Only eukaryotes perform mitosis, and since mitosis is a form of asexual reproduction, the cells that result from mitosis are "clones." These are referred to as daughter cells.
