Answer:
True
Explanation:
This given statement is true.
A dominant allele is the one which overrides the expression of the other allele of the same gene.
For instance,
R is a dominant allele and give red color to flowers while r is the recessive allele and give white color to the flowers
Rr together will give red color to flower because R will dominate r
Answer:
Tropospheric ozone is harmful, damaging plants and human health while ozone at the stratophere level screens out mutagenic ultraviolet radiation.
Explanation:
Ozone is dangerous and harmful in the lowest layer of the Earth's atmosphere. This layer is called troposphere. The reason why it causes damage to plants and human health it is because ozone is a reactive gas that affects plant synthesis and causes smog (a form of air pollution that is particularly dangerous to sensitive respiratory diseases such as asthma). However, ozone is helpful in the second layer of the Earth's atmosphere: the stratosphere. It prevents and blocks dangerous ultraviolet radiation.
The difference between a hypothesis and theory is that the hypothesis is based on observations, but doesn't have a solid proof, while the theory is based on solid proof.
So in order for the scientist to make his hypothesis into theory about the connection of all the Earth's oceans, will need to provide a proof. This proof can be obtained by a sea traveling that will be well documented, and during the travel the scientist to manage to sail through all of the Earth's oceans without having any physical obstacle between any of them.
Answer:
The correct option is: dew point temperature
Explanation:
Dew point refers to the temperature of the air when it is saturated with water vapor. The dew point temperature is dependent on the humidity in the air. It is <u>directly proportional to humidity and moisture content in air</u>. <u>Therefore, a lower dew point means lower moisture content. </u>
When the air is cooled beyond its dew point, the water vapour in the air condenses to liquid water, called dew.
