Answer:

0.00004524 minute

Explanation:

The enzyme is Catalase, and it speeds up the rate of reaction by 700 times than what it was supposed to be.

If the already sped up rate of reaction is 1.9 seconds, then the initial reaction ought to have taken

1.9/700 seconds and that is 0.0027143 second.

We're asked to convert to minute, we then have

0.0027143/60 which is equal to 0.0000452381 minute.

Since we're asked to round off to 4 significant figure, we have 0.00004524 minute.

Answer:

To know which exact organism you are referring to, and there is no confusion about it.

Explanation:

To identify organisms, we usually use two names. The common name and the scientific one.

Scientific name: binomial nomenclature.

The scientific name designates a species through binomial nomenclature. The binomial nomenclature is a standard agreement used to identify different organisms. It has international validity, and it does not change among regions or languages. One binomial name is used only on one organism and can not repeat.  It is composed of two Latin words: gender and the specific name. Many species might share the same gender for being very similar, so the specific name is used to identify each species.

Common names:

These are informal names, determined by the people of a region or area, that speak the same language. They are regional names, so they change from region to region, even when referring to the same organism. Usually, these names designate only organisms that have importance for the people. The same name might refer to different organisms, and in many cases, the same organism might receive many names. For this reason, there might be confusion when using only common names to talk about a species.

If we need to refer to a particular organism, we should always use the scientific name to avoid confusion. As it is internationally recognized and accepted, anybody can know which species you are talking about, independently of the region or the language. In most cases, people mention a species using the scientific name together with many of its common names.

Explanation:

Answer: mitochondrios produce energy from glucose, also C is right

Acidity rises and pH falls as carbon dioxide levels rise. The correct option is C.

A change in the characteristics of ocean water known as ocean acidification may be detrimental to plants and animals.

Scientists have noticed that the ocean's acidity is rising as a result of the water's absorption of atmospheric carbon dioxide.

Ocean acidification is the decrease in the ocean's pH level. The average pH of the ocean's surface fell from about 8.25 to 8.14 between 1751 and 2021.

Ocean water is more basic than drinking water because it is resistant to pH fluctuations due to the presence of various weak acids and their corresponding bases, or buffers.

The ocean is regarded as having a pH that is slightly alkaline. Acidity and pH both drop when carbon dioxide levels rise.

Thus, the correct option is C.
