(04.02 MC)What evidence supports the law of conservation of energy?
Light energy is converted to chemical energy during photosynthesis.
O Oxygen is made from the breakdown of carbon dioxide during photosynthesis.
O Energy is absorbed by chlorophyll during photosynthesis.
The sun gives off light energy that is absorbed by plants.

Answers

Answer 1

Answer:

Light energy is converted to chemical energy during photosynthesis.

Explanation:

The first law of thermodynamics, which is the LAW OF CONSERVATION OF ENERGY, states that energy can neither be created nor destroyed but can only be changed from one form to another. This law explains that the energy that exists cannot be made or destroyed, it can only be transformed from one of Its form to another.

The biological process of photosynthesis illustrates this law. Photosynthesis is the synthesis of organic molecules from inorganic molecules using the energy from sunlight. Plants, via their Chlorophyll pigment capture the light energy from the sun and use it to produce their food in form of organic molecules/glucose. This glucose is a chemical compound that stores energy in its chemical bonds.

Hence, photosynthesis supports the law of conservation of energy by changing/converting light energy from sun into a chemical energy in food (glucose).

Most tectonic plates have both oceanic and continental crust. How is oceanic crust different from continental crust

Answers

Tectonic plates are results of volcanic lava produces by an active volcanoes and the cause of its eruption is the activity of the earths movement in the mantle. So the different of the two is the oceanic crust is usually form in the ocean, this plates or crust are mostly younger that the continental crust and could be recycle, while the continental crust is usually old in age and contains land organism living and rich of mineral have been found

Which of the following is true of a eukaryotic cell in a multicellular organism? a.possess ribosomes b. possess a cell membrane c. possess a nucleus d. possess cytoplasm e. able to perform all life functions f. possess DNA

Answers

Answer:

c. possess a nucleus.

Explanation:

A eukaryotic cell may be unicellular or multicellular. Each cell possesses a well-defined or definite nucleus. Beside nucleus, each eukaryotic cell also has membrane-bound organelles such as mitochondria, chloroplasts, Golgi apparatus, endoplasmic reticulum. Ribosomes, a cell membrane, cytoplasm and DNA are present in all the prokaryotic and eukaryotic cells.

A cell is viewed under a microscope and is found to have two nuclear envelopes and spindles that appear to be breaking apart. Which phase of mitosis is the cell most likely in?a. Telophase
b. Anaphase
c. Metaphase
d. Prophase

Answers

c. Metaphase

The two identical daughter cells resulting from mitosis and cytokinesis are identical in the following ways:1. Mitosis occurs when the nucleus of the cell divides into two identical nuclei, each with the same type and number of chromosomes. The cell's DNA is duplicated during this phase. Sometimes the cell's DNA isn't copied properly resulting in cancer-type cells. 2. Cytokinesis is when the cytoplasm divides into two identical daughter cells. Each cell is genetically identical and both are a similar size.

A cell's digestive enzymes are enclosed in a membrane bound organelle. How can these molecules function of a plasma membrane

Answers

Answer:

A cell digestive enzymes are enclosed in a membrane bound organelles known as Lysosomes. Lysosome contains about 50 different types of enzymes which helping in breakdown of different types of biological molecules such as Protein, carbohydrates, nucleic acid and lipids.

Cells transporting the material into lysosome where digestive enzymes are present. Now the molecules are digested by enzymes after that these digested molecules are going back to the cytosol for use by the cell.

Enzymes which are present in lysosome require acidic environment to function in proper manner.

The membrane bound organelle you refer to is the lysosome. The lysosome fuses with a vacuole where it digest the contents.
