Answer:
Explanation: Carbon dioxide increases temperatures, extending the growing season and increasing humidity. Both factors have led to some additional plant growth. However, warmer temperatures also stress plants. With a longer, warmer growing season, plants need more water to survive.
☁️<u>My Answer☁️</u>:
The two things that identify something has matter are, physical and chemical properties.
⬇️
<u>✫Definitions✫:</u>
A physical property is an aspect of matter that can be observed or measured without changing its chemical composition.
A chemical property is a characteristic of a particular substance that can be observed in a chemical reaction.
<u>☼Examples of some major chemical properties☼:</u>
- Flammability
- Toxicity
- Heat of combustion
- pH value
- Rate of radioactive decay
- Chemical stability.
<u>❅Examples of physical properties❅:</u>

Answer:
Oncogenes result from a mutation in proto-oncogenes.
Explanation:
- Protooncogenes control the growth and division of cells.
- The proteins encoded by proto-oncogenes include growth factors, growth factor receptors, transcription factors and signal transducers.
- They contribute to the transformation process by driving cell proliferation or reducing sensitivity to cell death.
- Several types of genetic and epigenetic changes convert these proto-oncogenes to oncogenes.
- Oncogenes arise due to the changes that increases the expression of proto-oncogenes .
- Oncogenes are one of the causes of cancers.
A proto-oncogenes can turn into oncogene by following ways:
- A point mutation such as deletion, insertion and substitution in the proto-oncogene can lead to formation of oncogenes.
- Chromosomal translocation may result in activation of proto-oncogene as seen in Burkitt's lymphoma.
- Insertion of a mobile genetic material such as retrovirus changes the gene expression, but leaves their coding sequence intact.
- Activation of proto-oncogene can also occur from reduplication and amplification of DNA sequence.
The rain gauge is an instrument used by meteorologists to measure the amount of precipitation in a particular region in a particular amount of time.
The rain gauge is placed on the ground in order to collect the rain or the precipitation sample. The rain gauge is labelled with the quantities, which can be used to measure the amount of precipitation.
So, the correct answer is option (a). on or near the ground.
