Why do we use specific terminology when referring to the gender and species of common domestic animals?
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.
3. Which of the following statements best explains how the cell membrane 1 point
is selectively permeable? *
The movement of specific substances into and out of the cell is controlled by the cell
membrane
The movement of waste substances into, but not out of the cell is controlled by the
cell membrane
The cell membrane is inflexible and cannot control the movement of substances into
and out of the cell
The cell membrane does not surround the cell so it plays no role in the movement of
substances
Answer:
The movement of specific substances into and out of the cell is controlled by the cell membrane.
Explanation:
The cell membrane is permeable, so it allows for the passage of substances both into and out of the cell. It is also selective, so only specific substances can enter and exit the cell.

Which statement best describes the relationship between ocean co2 and ph
Acidity rises and pH falls as carbon dioxide levels rise. The correct option is C.
What is ocean pH?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.

6. Catalase is an enzyme that speeds up the breakdown of hydrogen peroxide. The enzyme increases the rate of reaction, so it is 700 times faster. If the enzyme reaction took 1.9s how long would the reaction take if there was no enzyme? Convert the answer to minutes. Give your answer to 4sf.
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.
Why do you think that some vaccines, such as the flu vaccine, need to be given every year?
Answer:
Because flu viruses evolve so quickly, last year's vaccine may not protect you from this year's viruses. New flu vaccines are released every year to keep up with rapidly adapting flu viruses.
Answer:
Because the virus/sickness would evolve and that vaccine might not protect you.
