The Celsius temperature scale is also something called the centigrade scale. Why is this?

Answers

There are three temperature scales in use today, Fahrenheit, Celsius and Kelvin.

Fahrenheit temperature scale is a scale based on 32 for the freezing point of water and 212 for the boiling point of water, the interval between the two being divided into 180 parts. The 18th-century German physicist Daniel Gabriel Fahrenheit originally took as the zero of his scale the temperature of an equal ice-salt mixture and selected the values of 30 and 90 for the freezing point of water and normal body temperature, respectively; these later were revised to 32 and 96, but the final scale required an adjustment to 98.6 for the latter value.

Until the 1970s the Fahrenheit temperature scale was in general common use in English-speaking countries; the Celsius, or centigrade, scale was employed in most other countries and for scientific purposes worldwide. Since that time, however, most English-speaking countries have officially adopted the Celsius scale. The conversion formula for a temperature that is expressed on the Celsius (C) scale to its Fahrenheit (F) representation is: F = 9/5C + 32.

Why are catfish and carp found at the mouth of a river, while trout are found nearer the source?

Answers

Answer:

The correct reason would be "the levels of dissolved oxygen at the mouth of the river and at the source of the river".

The mouth of the river is the region where it flows into the ocean, lake, another river, reservoir, sea et cetera. The level of dissolved oxygen in this region is too low to support great biodiversity.

Organisms like catfish and carp can survive here due to their low oxygen demand. For example, catfish can survive in water with an oxygen content of 2.5 parts per million.

In contrast, the level of dissolved oxygen is higher at the source of the river. Organisms like trout are found here due to their high oxygen need. For example, rainbow trout require minimum 5-6 parts per million dissolved oxygen for its survival.

Catfish and carp require less oxygen than trout. The mouth of a river usually has less oxygen and the area closer to the source has more oxygen, so since catfish and trout require more oxygen they typically are found at the source.

A gland secretes enzymes through a duct onto the surface of a body part. Which gland is it most likely to be?. . A.pituitary gland. . B.salivary gland. . C.thyroid gland

Answers

I believe the correct answer among the choices listed above is option B. A gland secretes enzymes through a duct onto the surface of a body part is a salivary gland. It is under the classification of exocrine glands. Hope this answers the question.

Answer: Salivary Gland

Explanation:

The salivary gland in human being is exocrine gland which helps in the production of saliva through a system of ducts.

Human beings have three paired major ducts in salivary glands that secrete their secretions in the mouth by the help of duct.

The main type of enzyme secreted is alpha-amylase which helps in the breakdown of starch into glucose and maltose.

Why is carbon so abundant in living things when oxygen is the most abundant element on Earth? Carbon atoms can bond with one another to make chains and cyclic structures whereas oxygen atoms cannot form chains or cyclic structures.
Carbon atoms are found in compounds that are solids at room temperature whereas oxygen atoms are found in compounds that form gases
Carbon atoms have lower mass than oxygen atoms, which keeps the masses of living things within desirable limits.
Carbon atoms are more stable than oxygen atoms, which allows living things to have more stable compositions.

Answers

Carbon is so abundant in living things even though oxygen is the most abundant element on Earth because carbon atoms can bond with one another to make chains and cyclic structures whereas oxygen atoms cannot form chains or cyclic structures.
The correct answer is the first option.
