Answer:
D) A and C
Explanation:
Gram staining is a laboratory technique used for bacterial species. It is used to differentiate between two groups of bacteria based on the components of their cell wall. Gram staining was developed by a scientist called Christian Gram in the year 1884. In the gram stain procedure, the following occurs:
- Due to the thick peptidoglycan component of their cell wall, GRAM POSITIVE bacteria retains the crystal violet due and stain VIOLET.
- On the contrary, due to the thin peptidoglycan component of their cell wall, GRAM NEGATIVE bacteria do not retain the crystal violet dye and hence stain, RED.
Based on this, a bacteria that has been gram stained has been tested for its GRAM REACTION and microscopic morphological characteristics, since it is a microbe.
Answer:
The tilt of earth's rotation axis stays the same as it orbits the sun.
Explanation:
The axis of the Earth is an imaginary line around which the Earth is known to orbit. The axis of the earth is known to tilt at an angle of 66 and a half degrees. The tilt of the axis of the Earth remains the same and it does nor change as the earth orbits around the sun. The orbiting of the Earth around its axis causes day and night to occur on the planet Earth. The rotation of the Earth around its axis is slowing with time.
Answer:
The answer is a codon. A codon is in a mRNA while an anti-codon is in a tRNA.
Acquired traits can be passed to offspring
Answer;
Carbon dioxide, water and light energy;
Explanation;
-Plants use a process called photosynthesis to make food. During photosynthesis, plants trap light energy with their leaves.
-Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy by the process of cellular respiration and may also be used to make other substances like cellulose and starch.
