Answer: Option D

Explanation:

Water is a polar molecule meaning that there is uneven distribution of electrons between the hydrogen atoms and oxygen atoms. The oxygen atom is electronegative and negatively charged and it attract more electrons while the hydrogen atoms is positively charged. For water to move up in trees in tubes, the tubes must be polar because water itself is a polar molecule.

tiny-mole [99]

A major function of the roots of a plant is to absorb water to produce food for the organism. They need water to produce the glucose product of food, the other reactant is carbon dioxide. This is the process of photosynthesis. The other product is oxygen

- Oxygen, substance all organisms require to survive.

- Glucose, substance produced and used by plant organisms for food.

- Reactant, substances used to make products.

- Carbon Dioxide, gas found floating in air, used by plants to make oxygen.

- Photosynthesis, the process where plants use their chlorophyll to make substances like food

Why are certain crops grow in a particular season? Give two reasons
weeeeeb [17]
The growing season is the part of the year during which local weather conditions (i.e. rainfall and temperature) permit normal plant growth. While each plant or crop has a specific growing season that depends on its genetic adaptation, growing seasons can generally be grouped into macro-environmental classes.

Key points: Cells have a variety of mechanisms to prevent mutations, or permanent changes in DNA sequence. During DNA synthesis,
MrMuchimi

Answer:

Explanation:

The above mentioned key points are mechanisms by which cells used to correct replication error and repair damaged DNA.

Proof Reading: while printing a page, the typesetter set the types and impression is taken, proof reading is done to correct mistakes if any, and the final printing is done. A similar follow up mechanism is done after DNA synthesis. If DNA polymerase detects an incorrect nucleotide pair, it will remove and replace with the correct nucleotide immediately.

Mismatch Repair:even after DNA synthesis, mismatch area(insertion or deletion) can be identified on the newly synthesized DNA.

In the mismatch repair, specific proteins scan the newly synthesized DNA strand. The mismatch area is identified and loop.

The second protein complex remove the mismatch segment. Finally correct segment is synthesized by the help of DNA polymerase, SSBs and ligase.

DNA damage repair mechanism: when DNA get damaged, there's a repair process that fix the damage. This includes Direct reversal, excision repair and Double stranded break repair
