The answer is A. An electrocardiogram (EEG) measures the electrical activity of the heart to see if there’s any irregularities in the heartbeat. Irregularities in your heartbeats can be caused by many things including blockages which can cause strokes and heart attacks. It’s a good idea for students or any athletes to get an EEG as part of their physicals to rule out any heart issues.
Answer:
e. is mostly asexual, with sexual as a second option.
Explanation:
Protist are unicelluar eukaryotic microorganims. Example include:
<u><em>Amoeba</em></u> <u><em>proteus</em></u>
<u><em>Euglena</em></u><em> </em><u><em>viridis</em></u>
Dinoflagellates, etc.
Among the species of Protists, each species exhibit a unique way of reproduction. Generally, in Protist there are two types of reproduction, these are asexual reproduction and sexual reproduction. With asexual reproduction being the primary mode of reproduction in most protists.
Protist reproduce asexual by binary fission or by budding.
Binary fission occurs when a single protist divides its nucleus and then divides itself into two separate organisms.
Budding occurs when a new organism grows from the body of the parent organism. The new organism may separate from the parent or remain attached, forming colonies.
They also reproduce sexually by conjugation.
Sexual reproduction by conjugation requires two parent organisms contributing to the genetic material of the offspring. The essence of conjugation is to produce a new offspring with a wider genetic variability i.e the offspring being genetically different from the parent organisms.
Answer:
D) They can increase the reaction rate for a given reaction by a thousand-fold or more.
Explanation:
Enzymes are like catalysts with the only difference that they are bio-molecules. Biochemical/chemical reactions are slow because of 'transition state barriers' which require a lot of energy to overcome so enzymes rather than overcoming transition state barrier provide an alternate pathway for biochemical reactions which require comparatively less energy. Thus presence of an enzyme leads to an increase in reaction rate because alternate pathway which requires less energy makes the rate of chemical reaction rapid by a thousand-fold or more.
