Answer:
7 protons, 7 neutrons (READ EXPLANATION)
Explanation:
The atomic number represents how many protons are in an element. Generally speaking, elements have the same number of protons and neutrons. So, an element with the atomic number of 7 will have 7 protons and 7 neutrons.
However it is possible for an element to have a differing number of neutrons (an element will always have the same number of protons because that number is how the element is identified in the first place). Elements that have a number of neutrons that is not the same as the atomic number are called isotopes.
Discuss what is respiration and why is it important.
Answer:
Respiration is the chemical process by which organic compounds release energy.
Explanation:
Respiration is important because it produces energy that is essential for the normal functioning of the body. Respiration provides cells with oxygen and expels toxic carbon dioxide. Some energy released by respiration is also in the form of heat.

mushrooms get their nutition by
Answer:
Most mushrooms are considered saprophytes — they get their nutrition from metabolizing non living organic matter. Nutrients and other essential compounds are stored in their bodies, and when there is enough material stored and the conditions are right they start to fruit or produce mushrooms.

how do the germinal discs differ between the eggs?why?
Answer:
Germinal disk (blastoderm) -- a small, circular, white spot (2-3 mm across) on the surface of the yolk; it is where the sperm enters the egg. The nucleus of the egg is in the blastodisc. The embryo develops from this disk, and gradually sends blood vessels into the yolk to use for nutrition as the embryo develops.
Explanation:
Which is not an example of evolution?
A. The long necks of giraffes.
B. The different beaks of Galapagos finches
C. Changing color of peppered moths
D. The disappearance of the dodo
Answer:
D. The disappearance of the Dodo.
Explanation:
The answer should be D. because evolution is how organisms or things change over a period of time. The Dodo becoming extict or diappearing does not have anything to do with evolution.

What is a disadvantage to Hydroelectricity?
Answer:
Water levels are lower than usual.
Answer:
Hydropower can impact water quality and flow. Hydropower plants can cause low dissolved oxygen levels in the water, a problem that is harmful to riparian (riverbank) habitats and is addressed using various aeration techniques, which oxygenate the water.
The parasitic sac fungus that grows on rye and other grains and contains the hallucinogenic chemical lysergic acid is?
If a bird eats a mouse that eats grass, the bird is a(n)
o producer.
O second-level consumer.
O first-level consumer.
decomposer.
Answer:
First level consumer
Explanation:
First level consumers eat plants eat producers that make their own food, therefore making the mouse a first level or primary consumer.

Why was the potato easier to balance on the ruler when the forks were added
Answer:
More weight.
Explanation:
Explanation:
In these amazing science experiments you will learn how to balance a potato, fork and a pencil on a table so that only the tip of the pencil is touching the edge of the table. Think its impossible? Not if you follow the directions and do some experiment on your own. Plus these seemingly gravity defying experiments are fun to do.

How will your participation in the STEM Core Program help you meet your education and career goals? *
Answer:
STEM training helps students develop critical thinking skills.
Explanation:
Curiosity and problem-solving are at the root of success in the professional world, not only in STEM, but in all industries. But particularly in STEM fields, where change is the only constant, students must learn to embrace a difficult challenge and devise a creative solution.

where a river dumps into the ocean
Answer:
The correct answer is high rates of evaporation
Answer:
high rates of evaporation and freezing of iceberg.
Explanation:
high rate of evaporation and freezing of iceberg increase the salinity of the ocean.

when do plants use oxygen
Answer:
When there is no sunlight and they undergo cellular respiration
Explanation:
Plants respire to get energy like animals. In this chemical process, glucose food breaks down in the presence of oxygen to form carbon dioxide and water with the release of energy. See the diagram below

5. What would be the harm in having a captive animal intended for release imprinting on its human handlers?
Answer:
If we release a captive animal imprinted on human then the animal won't recognize other animals of its species as same as itself . It won't mate with its species rather it would try to mate with humans. It would not behave normally. The behaviour would not be typical of other members of its species.
