The most abundant elements in the body are hydrogen, oxygen, carbon, and what?

Answers

Answer: The correct answer is nitrogen, calcium and phosphorus.

Explanation:

Elements are defined as the substances which are made out of same type of atoms. For Example: Hydrogen, Oxygen etc..

Human body is made up of various types of elements in which 6 are most abundant.

Almost 99% of the mass of human body is made up of mainly six elements. They are oxygen (O), carbon (C), hydrogen (H), nitrogen (N), calcium (Ca) and phosphorus (P).

About 0.85 % of mass of human body is composed of other 5 elements which are potassium (K), sulfur (S), sodium (Na), chlorine (Cl) and magnesium (Mg).

Hence, the correct answer is nitrogen, calcium and phosphorus.
Nitrogen, Phosphorous, and Sulphur. Remember the acronym CHNOPS: Carbon, Hydrogen, Nitrogen, Oxygen, Phosphorous, and Sulphur

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.

What is the primary reason the signaling molecule is not received by every cell nucleus? Option 1: Cell nuclei have varying sizes. Option 2: The signaling molecule is too large. Option 3: Not all cells have receptors for the molecule. Option 4: The molecule is rapidly degraded.

Answers

Answer:

3. Not all cells have receptors for the molecule.

The main reason a signaling molecule is not receive by every cell nucleus is that not all cells have receptors for that particular molecule. Cells have specific receptors on their surface to recognize and respond to their corresponding signaling molecule. Cells that lack the specific receptors for a given signaling molecule will not respond to it, regardless of the size of the cell nuclei or other factors such as the stability of the molecule itself.

The transport tissues of vascular plants are the _____ and _____. xylem; cortex phloem; pith xylem; phloem parenchyma; collenchyma

Answers

The answer is xylem and phloem.

Xylem and phloem are the transport tissues of vascular plants. Parenchyma and collenchyma are ground tissue, while pith and cortex are stem tissue.
Xylem and phloem provide transportation of water, minerals, food, and nutrients. Xylem transport water and minerals from the root to the upper parts of the plant. Phloem transports food and nutrients from the leaves, where they are produced, to the growing or storage parts of the plants.

Explain the relationship between adaptation natural selection & evolution

Answers

Adaptations are the result of evolution in different living organisms. This process occurs amazingly through gene mutation but it takes a very long period in time. Adaptation processes occur to help species survive and thrive in the ecological balance of life. Structural adaptations are physical features of an organism that adapted through time. An example of this are the bills of a bird and the fur of bears that they generally need for their survival; birds for hunting, and bears to protect them from low climate areas.

Natural selection is a process by which organisms better adapted to their environment tend to survive, reproduce, increase in number, and pass their traits to succeeding generations. Adaptations are inherited or learned traits that increase an organism's chance of survival in an environment. Evolution is a process of change in a population through genetic variation over time. Natural selection drives evolution.
