The boundary that separates different air masses is called a(n)?

Answers

Answer 1
Answer:

The boundary that separates different air masses is called a front.

A front is the boundary (transition zone) that separates two air masses of different density, different air temperature, different levels of humidity, pressure and wind direction. Front often result in precipitation and causes weather. Cold fronts and warm fronts are the two major types of fronts.
Answer 2
Answer: it is known as the front

What are acquired traits why are the streets generally not inherited over generation explain​

Answers

Answer:

Acquired traits are due to changes in the life style, injury, loss of body parts, disuse of some body parts. These are the traits which occur in the somatic cells. Changes in the somatic cells are not passed on to the offspring belonging to next generation. Hence acquired traits cannot be passed on to next generation.

Energy is released from ATP when

Answers

Answer: The correct answer for the blank is-

Energy is released from ATP ( adenosine triphosphate) when high energy phosphoanhydride bond ( present between two phosphate) is broken down or hydrolyzed.

This results in the formation of ADP ( adenosine diphosphate) and Pi ( inorganic phosphate).

Therefore, hydrolysis of ATP releases energy.

Energy is released from ATP when ATP undergoes hydrolysis.

ATP supplies energy for cellular activities by breaking off a phosphate group from its structure.

ATP is produced through the process of cellular respiration where food particles such as glucose are broken down to yield energy in the form of ATP.

Further Explanation

Cellular respiration

  • Cellular respiration is the process of by which living organisms use nutrients or food substances to generate energy in the form of ATP that is required to drive cellular processes.
  • Cellular respiration takes place in an organelle known as mitochondrion which is known as the powerhouse of the cell.
  • Cellular respiration takes place in three stages; glycolysis, Kreb's cycle and electron transport.  
  • Each step of cellular respiration yields ATP with the electron transport chain yielding the most number of ATP molecules, 34 ATP molecules.

ATP

  • ATP is the energy carrier molecule in the cells of living organisms. It is the usable form of energy by the cells in all living forms. Cells use ATP to drive all the cellular activities such as transport, excretion, growth and development, etc.
  • ATP is produced through the process of cellular respiration where food particles such as glucose are broken down to yield energy in the form of ATP.

Hydrolysis of ATP

  • ATP molecule is made up of a nucleotide base adenine attached to three phosphate groups.
  • Energy is contained in the bonds between the phosphates in an ATP molecule which is released when they are broken through the addition of water molecules a process called hydrolysis.
  • ATP powers cellular processes by transferring phosphates group in its structure to other molecules which releases energy required to drive the cellular activities.

Use the word "passive transport" in a sentence.

Answers

 " What does passive transport mean " Good  sentence or no

Final answer:

Passive transport refers to the movement of molecules across cell membranes without requiring energy, aiding in maintaining balance within the cell. An example sentence is 'Oxygen molecules move from a region of high concentration to a region of low concentration via passive transport.'

Explanation:

Passive transport is a biological concept pertaining to the movement of molecules across cell membranes. Here is a sentence using the term: 'Oxygen molecules move from a region of high concentration to a region of low concentration via passive transport.' This means that oxygen molecules, without requiring energy, naturally move towards areas with fewer oxygen molecules. It is the cell's way of maintaining balance or homeostasis, a crucial aspect of cellular function.

In the diagram, AC¯¯¯¯¯ is a diameter of the circle with center O. If m∠ACB = 50°, solve for m∠BAC.A. 50°
B. 40°
C. 80°
D. 100°

Answers

Answer;

B. 40°

m∠BAC = 40°

Explanation;

  • In the question AC is the diameter of the circle.
  • ACB  is a triangle with angles m∠BAC,  m∠ACB  and  m∠ABC.
  • Angles subtended  by a diameter to the circumference of a circle is always right angle or 90 degrees.
  • Therefore, angle m∠ABC, which is subtended by diameter AC to the circumference is 90 degrees.

But, angles in a triangle adds up to 180 degrees, therefore;

m∠BAC = 180 - (m∠ACB + m∠ABC)

             = 180 - (50 + 90)

             = 180 - 140

             = 40°

Thus; m∠BAC = 40°

The solution of  m∠BAC is mathematically given as

m∠BAC = 40°. This is further explained below.

What is angle

The angle formed by two crossing lines or surfaces, commonly expressed as a number of degrees.

What is the solution of  m∠BAC?

Generally, the equation for angle m∠BAC  is mathematically given as

m∠BAC = 180 - (m∠ACB + m∠ABC)

m∠BAC = 180 - (50 + 90)

m∠BAC = 40°

In conclusion, m∠BAC = 40°
