Answer:
Severe weather can occur under a variety of situations, but three characteristics are generally needed: a temperature or moisture boundary, moisture, and (in the event of severe, precipitation-based events) instability in the atmosphere.
Every year in the United States, tornadoes do about 400 million dollars in damage and kill about 70 people on average. Extremely high winds tear homes and businesses apart. Winds can also destroy bridges, flip trains, send cars and trucks flying, tear the bark off trees, and suck all the water from a riverbed.
What are the substances?
Explanation:
What types of plants and animals do you think live at Guadalupe Park in Texas (https://www.nps.gov/gumo/learn/nature/index.htm)?
How might the weathering and erosion that's occurring there affect the plant and animal life over time? Are these changes short-term or long-term?
Answer these questions in a few short paragraphs.
Answer:
Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering.

Describe the inheritance pattern of blood types. Describe the inheritance type of different hair colors. Why are each unique?
how can you explain what you know about the heavily muscled cows with what you have learned about mutations, patterns of inheritance, incomplete dominance, sexaul reproduction, selective breeding and transferring of genetic information?
Myostatin (GDF-8) is a member of the transforming growth factor β superfamily of secreted growth and differentiation factors that is essential for proper regulation of skeletal muscle mass in mice. Here we report the myostatin sequences of nine other vertebrate species and the identification of mutations in the coding sequence of bovine myostatin in two breeds of double-muscled cattle, Belgian Blue and Piedmontese, which are known to have an increase in muscle mass relative to conventional cattle. The Belgian Blue myostatin sequence contains an 11-nucleotide deletion in the third exon which causes a frameshift that eliminates virtually all of the mature, active region of the molecule. The Piedmontese myostatin sequence contains a missense mutation in exon 3, resulting in a substitution of tyrosine for an invariant cysteine in the mature region of the protein. The similarity in phenotypes of double-muscled cattle and myostatin null mice suggests that myostatin performs the same biological function in these two species and is a potentially useful target for genetic manipulation in other farm animals.
The transforming growth factor β superfamily encompasses a large group of secreted growth and differentiation factors that play important roles in regulating development and tissue homeostasis (1). We have recently described a member of this family, myostatin, that is expressed specifically in developing and adult skeletal muscle and functions as a negative regulator of skeletal muscle mass in mice (2). Myostatin null mice generated by gene targeting show a dramatic and widespread increase in skeletal muscle mass. Individual muscles in myostatin null mice weigh 2- to 3-fold more than those of wild-type mice, primarily due to an increased number of muscle fibers without a corresponding increase in the amount of fat. To pursue potential therapeutic and agricultural applications of increasing muscle mass by inhibition of myostatin activity, we have been characterizing myostatin in animals other than mice. Here we report that the myostatin gene is highly conserved among vertebrate species and that two breeds of cattle that are characterized by increased muscle mass (double muscling), Belgian Blue (3) and Piedmontese (4), have mutations in the myostatin coding sequence. These results demonstrate that the function of myostatin has been highly conserved among vertebrates. hope it helps

Which process does a plant use to release energy from food?
photosynthesis
reproduction
respiration
transpiration
Answer:Its photosynthesis
Explanation:
Answer:
photosynthesis
hope it helps
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.

Explanation:
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

How are birds adapted for flight? What are the uses for feathers?
Answer:
Instead of heavy jaws and teeth, they have lightweight beaks. And instead of fur, they have feathers. These are light, streamlined and cleverly adjustable for flight control. Their bones are also hollow making them lighter for flight

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.

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.

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.
