Can i have brainliest plsA Paramecium (a single celled organism) swims into an area of salty water.. The Paramecium shrivels up as it loses water through its cell membrane. Explain what happened.
The paramecium lost water and shrank as a result of the water within being drawn to the high concentration of salt outside and moving through the cell membrane. This was due to osmosis.
What is osmosis?
Osmosis is a passive process that doesn't require any energy to complete. In order for the concentrations on either side of the membrane to be equal, molecules must shift from an area of greater concentration to one of lower concentration.
Any solvent, including gases and supercritical liquids, can go through the osmosis process.
When solute concentrations inside and outside of the cell are equal, an isotonic solution has been created. When the concentration of solutes outside the cell is higher than within, the solution is said to be hypertonic. When the concentration of solutes inside the cell is higher than outside, the solution is said to be hypotonic.
Therefore, the high concentration of salt outside attracted the water inside the paramecium, which migrated through the cell membrane and caused the paramecium to lose water and shrivel.

What type of volcano is commonly found in the Pacific Ring of Fire?
a. Stratovolcano
b. Cinder Volcano
c. Scoria cone
d. Shield volcano
Answer:
d. Shield volcano
Explanation:
The type of volcano that is commonly found in the Pacific Ring of Fire is Stratovolcano.Therefore, the correct option is A.
What is the Pacific ring of Fire?The Pacific Ring of Fire is a region around the Pacific Ocean characterized by frequent earthquake and volcanic activity. Stratovolcanoes, also known as composite volcanoes, are steep-sided, cone-shaped volcanoes built up by the accumulation of layers of ash, lava, and other volcanic material.
They are known for their explosive eruptions and can be found along many of the tectonic plate boundaries in the Pacific Ring of Fire, including the Andes, Cascade Range, and Japan. Other types of volcanoes, such as shield volcanoes and cinder cones, are also found in the region, but stratovolcanoes are the most common.Therefore, the correct option is A.

Which of the following is true about the role of genetic and environmental factors in human health?
A) Genes are the only factor affecting whether or not an idividual will contract a disease.
B) Genetic factors are more important than environmental factors in determining an individual's
personal health risks.
C) Individuals can influence their health by controlling their genetic traits.
D) Environmental factors determine whether or not all genetic traits lead to health issues.
E) Certain environments can lead to an increased risk of developing certain diseases.
Answer: E) Certain environments can lead to an increased risk of developing certain diseases.
Explanation: This is the most logical answer since environmental factors, such as pollution, can increase one's risk of developing certain diseases.
A. is incorrect because genetic factors are not the only things that affect individual health. One's environment also factors in. If one lives a healthy lifestyle, they can help prevent themselves from developing disease that are more "encouraged" by their genes. An example would be a genetic trait that increases one's risk for heart disease. One can work to avoid heart disease by utilizing a healthier lifestyle.
B. is wrong because environmental factors play an equal role in determining if one will develop some genetically linked diseases.
C. is incorrect because as it stands, one cannot control their genetic traits.
D. is incorrect because some diseases, such as cystic fibrosis and sickle cell anemia are genetically inherited diseases which cannot be prevented by environmental factors. This is not to say that environmental factors are independent of all genetically linked diseases, but not all diseases can be prevented by environmental factors.

Carbon and hydrogen
Calcium and silicon
Hydrogen and oxygen
Nitrogen and phosphorus
Answer:
hydrogen and oxygen snsnsn
The oceans are primarily composed of carbon and hydrogen elements.
What are elements?An element is a substance that cannot be broken down into a simpler format. They are distinguished by a unique atomic number. The elements are organized by their atomic number in the periodic table, which highlights elements with similar properties.
The six elements found in all organisms are carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur; collectively called biological elements and shown as the acronym CHNOPS. These elements can bond with each other as well as other elements to create molecules.
Four elements—carbon (C), oxygen (O), hydrogen (H), and nitrogen (N)—make up 96% of living matter. Most of the remaining 4% of an organism's weight consists of phosphorus (P), sulfur (S), calcium (Ca), and potassium (K).

Sam has a mutation in a gene that affects the function of a transfer RNA (tRNA). Human cells have 20 different types of tRNAs, and each adds a different amino acid to growing peptide chains, which form proteins. Based on what you know so far, would you expect this mutation to affect all proteins produced in Sam's cells? Explain your reasoning.
Answer:
No
Explanation:
The mutation is not expected to affect all the proteins produced in Sam's cells because each protein has a different structure and functions. Proteins are polymers of amino acids and the component amino acid for each protein diffesr. Hence only the proteins whose constituent amino acids include the amino acid being carried by the mutated tRNA would be affected. Others whose constituent amino acids do not include the amino acid being carried by the mutated tRNA would function normally.

Explain a wedge and give 3 examples.
Answer: A wedge is basically an incline plane. Often portable used for many purposes
Explanation: A wedge is a double inclined plane such that the two sloping surfaces taper to form either a sharp edge or a pointed edge. For example, a knife, an axe etc.
In a few cases, the number of inclined planes used can be more than two as well. In such cases, the sloping surfaces generally taper to form either a very sharp or a pointed edge to split or pierce materials. For example, pins, nails etc.
The front end of a boat is shaped like a wedge so that it can easily cut across the flowing water.
