Answer: The image to be studied is missing from the question,so I attached it to my answer,please click on the attachment provided to view the image being studied.
The correct answer to the question is option A.
NEBULA
The object shown in the image is known as a nebula.
Explanation: A nebula is found in interstellar space,it has a form of a giant cloud of dust. When some stars goes into dying process,they explode throwing out gas and dust which forms a nebula.(a supernova remnants nebulae).
Some nebulae(singular form of nebula) are also found where new stars are being formed.
Nebula are the basic building blocks of the universe,they are made up 90% hydrogen,10% helium and other heavier elements in trace amounts from which stars and other solar systems are made.
Nebula exist in 5 distinct types namely;
Emission nebulae, Reflection nebulae,Dark nebulae, Planetary Nebulae and supernova remnants Nebulae.
Answer: The oxygen content of the water decreases
Explanation:
The sun shining on a tidal pool during a hot day heats the water, causing some water to evaporate. Because the water has become warmer and saltier, the oxygen content of the water decreases.
The temperature and the salt content of a body of water determines how much oxygen it can hold.
The oxygen content of warm water decreases because the temperature of the water causes the water molecules to move faster. This leads to the expulsion of oxygen from the water, making it contain less oxygen.
Also, salty water will lead to a decrease in oxygen because of the presence of sodium chloride ions.
Therefore, a warmer and saltier water will contain a less amount of oxygen.
Answer: One of the most common Monera is Escherichia coli, also known as E. coli. "[E. coli] is a Gram-negative, facultative anaerobic, rod-shaped, coliform bacterium of the genus Escherichia that is commonly found in the lower intestine of warm-blooded organisms." States wikipedia.* Signs of E. coli are stomach pains and cramps, diarrhea that may range from watery to bloody, fatigue, loss of appetite or nausea, vomiting, and low fever < 101 °F/ 38.5 °C (not all people have this specific symptom).
E. coli comes from human and animal wastes. During precipitation, E. coli may be washed into creeks, rivers, streams, lakes, or groundwater. Another way to get it is from contaminated food, a lot like corona virus. When cattle are slaughtered and processed, E. coli bacteria in their intestines can get on the meat. And when ground beef is made, it combines meat from many different animals, increasing the risk of contamination.
Explanation:
The answer is false. All cells that had undergo in the beginning of mitosis, will be undergoing to the whole stages of mitosis. Mitosis is the part of the cell cycle, wherein it results into equally distributed chromosomes and separated two new nuclei. Typically there are five stages of Mitosis.
The correct answer is mRNA.
mRNA or messenger RNA is synthesized during the process of transcription, from DNA molecule which is used as a template. mRNA contains information about protein synthesis (translation) in the form of nucleotide triplets or codons.
In the example above: reference book is DNA molecule (template for copies), copies are mRNA, wood is amino acids (building blocks) and doghouse is protein.
