Answer:
New mutations will become permanent
Explanation:
Human MutL homolog 1 (MLH1) gene is a well-known tumor suppressor gene that encodes for a DNA mismatch repair protein. The MLH1 protein is part of the DNA mismatch repair (MMR) genetic system which recognizes and repairs the incorrect addition of nucleotides during DNA replication and recombination. It has been shown that inherited mutations in one allele of the MLH1 gene increase the risk of cancer, especially colorectal cancer.
Which statements about light microscopes are correct?
1. To calculate the magnification of a light microscope the eyepiece lens and objective lens magnifications are added together.
2. As the magnification increases the resolution decreases.
3. The resolution of a light microscope is limited by the wavelength of light.
4. The scale on a stage micrometer is resolved more clearly than an eyepiece graticule.
1,2,3 and 4
1,2,3 and 4
1,3, and 4 only
1,3, and 4 only
2 and 3 only
2 and 3 only
2 and 4 only
2 and 4 only
C. 2 and 3 only
Light Microscope:The light microscope is an instrument for visualizing fine detail of an object. It does this by creating a magnified image through the use of a series of glass lenses, which first focus a beam of light onto or through an object, and convex objective lenses to enlarge the image formed.The resolution of the light microscope cannot be small than the half of the wavelength of the visible light, which is 0.4-0.7 µm. The resolution of a light microscope is limited by the wavelength of light. Resolution is a somewhat subjective value in optical microscopy because at high magnification an image may appear unsharp but still be resolved to the maximum ability of the objective.Thus, statements 3 and 4 are correct. Therefore option C is right choice.

Adenosine Triphosphate is the primary source of energy for all cells. When comparing the products of cellular processes, which process is responsible for the production of ATP? -Photosynthesis -Phagocytosis
-Cellular Respiration -Excretion
Answer:
The correct answer is - cellular respiration.
Explanation:
Cellular respiration is the cellular biochemical process that includes different sets of chemical reaction takes place in mitochondria of the cell from glucose or sugar to the release of a huge amount of chemical energy in the form of ATP with carbon dioxide and water as a byproduct.
ATP or adenosine triphosphate is the basic and primary form of energy used by the cell. Following equation can summarize the complete production of energy from stored nutrients.
C6H12O6 + 6O2 → 6CO2 + 6H2O+ energy (38 ATP)
