Answer: Option A
Explanation:
Birds attach the bur of the plant which helps in the pollination. The birds sit on the plant and the burs of the plant gets attached in the legs of the birds which is transferred from one place to another.
Seeds at a different place will help in reproduction and growth of the plants. In this case the birds are carrier of the burs.
This is how the birds help in the reproduction of the plants by becoming the messenger.
Viral infection can be asymptomatic (latent) or can lead to cell death (lytic infection). The life cycle begins with the penetration of the virus into the host cell. Next, the virus is uncoated within the cytoplasm of the cell when the capsid is removed.
I think you b and c is the other way around.

The air pressure on your body is about 10kg same as the weight of 2 elephants
Answer:
precipitation and temperature
Explanation:
Temperature and water are considered major abiotic factors that affect species distribution in terrestrial ecosystems. The temperature can affect the distribution of terrestrial organisms due to many species maintain a constant internal temperature, while other species maintain a body temperature range that may be very different from the environmental temperature, and therefore they will not be able to carry out their metabolic functions. Hibernation is an adaptation that allows some terrestrial animals to escape temperature fluctuations. Moreover, water is another limiting factor for life, since water is critical for cellular processes. The waxy cuticle is an adaptation that allows terrestrial plants to avoid excessive water loss through transpiration.
Answer:
Gene Therapy
Explanation:
<u>Gene therapy</u> is an attempt to correct a genetic disorder by replacing a mutated gene with a normal allele.
Gene therapy introduces a normal copy of the gene to restore the function of the protein if a mutated gene causes a necessary protein to be faulty or missing.
Gene therapy is a process in which a new, correct version of the cystic fibrosis transmembrane conductance regulator gene would be placed into the cells in a person's body.
