Answer:
38. Chlorophyll's job in a plant is to absorb light—usually sunlight. The energy absorbed from light is transferred to two kinds of energy-storing molecules. Through photosynthesis, the plant uses the stored energy to convert carbon dioxide (absorbed from the air) and water into glucose, a type of sugar.
39. The energy from light causes a chemical reaction that breaks down the molecules of carbon dioxide and water and reorganizes them to make the sugar (glucose) and oxygen gas
40. Without enough light, a plant cannot photosynthesise very quickly - even if there is plenty of water and carbon dioxide and a suitable temperature. Increasing the light intensity increases the rate of photosynthesis, until some other factor - a limiting factor - becomes in short supply.
41. Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

Answer:
This question is asking to fill the blank spaces. The answers are:
1. Capsid
2. Cell content
Explanation:
A virus is an organism that is incapable of reproducing itself without invading an host cell. It is generally made up of a genetic material (DNA or RNA), and a protein coat called capsid. This CAPSID is the part of the virus that protects its genetic material and content.
This function of capsids is similar to that of the cell membrane in prokaryotic and eukaryotic cells as they both function to protect the cellular content including the genetic material.
Answer:
45 chromosomes (2n1 + n2)
Explanation:
The allotetraploid 2n1+2n2=60 has 60 chromosomes total, two sets of them of type 1 and two sets of chromosomes from the other type (2).
If the suspected type 1 parent is diploid with 30 chromosomes, then the allotetraploid has 30 type 1 chromosomes and 30 type 2 chromosomes.
<u>During meiosis, the germ cells reduce the total chromosome number by half.</u>
- The gametes produced by the allotetraploid will have 15 type 1 chromosomes and 15 type 2 chromosomes.
- The gametes produced by the suspected parent will have 15 type 1 chromosomes.
When these gametes combine during the backcross, the F1 zygote will have a diploid number of 30 type 1 chromosomes (15 coming from the allotetraploid and 15 coming from the suspected parent) and 15 type 2 chromosomes (which will be haploid because they all came from the allotetraploid).
