Etymologically 'analytic' means to provide an analysis of something. A detailed analysis is done by dividing it into smaller parts. The synonym of the term 'analytic' is 'systematic' and 'logical'.
In the given phrase, the term that can be used as a synonym of 'analytic' is 'logical'. All the other three terms do not provide a synonymous meaning to the given word. The methods used in scientific approaches are logical and they provide meaningful and reasonable details about the occurring of the things.
Certain cell organelles are present only in plant cells like chloroplast and certain only in animal cell like centrioles.
Explanation:
The concept can be explained in three stages:
<u>Organelles only in plant cells</u>- <em>Chloroplast</em> is an organelle which is helpful in photosynthesis. Since animals don't perform photosynthesis, they don't need it. Plant cells also have a <em>cell wall</em> on top of a cell membrane.
<u>Organelles only in animal cell</u>- <em>Centrioles</em> are present in animal cells which help in movement through structures like <em>flagella and cilia.</em>
<u>Organelles present in both plant and animal cells</u>- <em>Ribosomes, nucleus,mitochondria, golgi complex, cell vacuoles, lysosomes</em> are present in both plant and animal cells.
(D) The protein that is first made gets modified afterwards
Explanation:
The first amino acid in any protein in eukaryotes is always methionine (Met). But, in some proteins any amino acid other than methionine may be found at N terminus of a protein. Like in this example, the HBB protein starts with a valine (Val) instead of methionine. It happened because of post-translational modification which includes the action of aminopeptidases which cleave 1 or 2 amino acids from N terminus of a protein as a result of which any amino acid other than methionine may exist at amino terminus.
Yes. Upper-layer skin cells and the cells in the front surface of the eyes get a significant amount of oxygen directly from the air rather than from the blood. Human bodies have a huge demand for oxygen. As a result, the oxygen that is able to passively diffuse into the body directly from the air is not nearly enough to run the whole body. Fortunately, we have lungs that can actively pull in oxygen and transfer it to the blood, allowing the body to transport oxygen to the cells by using the blood like a fleet of delivery trucks. Most of our cells rely on the blood delivery service. However, the cells in the outer layers or our skin and eyes are in direct contact with the atmosphere and can efficiently get their oxygen right from the air.
Yes, there are nuclear reactions constantly occurring in our bodies, but there are very few of them compared to the chemical reactions, and they do not affect our bodies much. All physical objects are made of molecules. A molecule is a series of atoms linked together by chemical (electromagnetic) bonds.
Photon wave phase can also not be directly detected by humans but can be detected by machines called interferometers. Phase information is often used to determine the flatness of a reflecting surface. In summary, humans can indeed see photons. Humans can see all of the properties of photons except for spin and wave phase.
Mechanical Weathering occurred. Is not caused by any chemical substance. Differs from Chemical Weathering which changes the composition of the rock itself
