Bats were found to have a vocal range of 7 octaves, nearly twice that of humans.
What is vocal range?
Vocal range, in its broadest sense, refers to the entire range of notes that a singer's voice is capable of producing, from the lowest note to the highest note. Range, then, is the difference between the highest and lowest notes a singer is capable of singing.
Three and a third octaves are typical for human vocal range.
Being put into one of these categories merely indicates where your voice is most naturally strong; it does not preclude you from singing other notes. These vocal range categories are bass, baritone, tenor, alto, mezzo-soprano, and soprano, in that order.

Answer: a. Intervention study
Explanation:
In an interventional research study the participants receive an intervention as they are given a new item or commodity to use and the results of use are evaluated on the basis of change made by the commodity on the participant. Such studies are used for the purpose of clinical trails.
The given research design is the example of interventional study. As the margarine is a new commodity the ingredients of which are claimed to lower down the blood cholesterol levels which can tested by comparing the cholesterol levels in people.
NO, they should not.
Erythrocytes, leucocytes, and proteins (albumin)
are not small enough to pass through the capillaries of the
glomerulus unless there is damage to the glomerulus. However, glucose does pass through into the glomerular filtrate. Nonetheless, glucose is fully reabsorbed back in the proximal
convoluted tubule (unless you have severe diabetes).
The difference between animal and plant cells is that they contain different organelles, among these are the chloroplasts that plant cells contain and animal cells do not.
<h3>What are the differences between animal and plant cells?</h3>
Each of these cells will have their own requirements, which is why they will have different types of organelles to be able to meet these requirements. Among the differences will be that plant cells will have chloroplasts to be able to generate their own food since they cannot obtain it by other means, so they will manufacture sugar through sunlight.
In plant cells it will have a cell wall that will be surrounded by a cell membrane. While animal cells will not have this cell wall.
Therefore, we can confirm that plant cells and animal cells will have differences in their content, function and organelles.

Answer:
The correct answer will be options 2 and 4.
Explanation:
Classification is a taxonomical system of identification, nomenclature and arrangement of the unidentified organism in taxonomical categories based on the similarity of the characters.
This method is used in the identification of new species by comparing the characters with other identified species based on the similarities which are then arranged into taxonomical categories and nomenclature method is performed thereafter to name the unidentified organism.
Thus, options 2 and 4 which include identification and nomenclature are the correct options.
