Answer and Explanation:
The process of transmission of heat due to the movement of molecules in the fluid is called convection. Convection also takes place on a global scale. At the equator, warm and less dense air tends to flow and rise towards the poles. Then denser, cooler air sinks and flow back towards the poles. Due to the rotation of earth rising warm air from the poles does not make it all the mode towards the pole. The combination of the earth’s rotation and global convection makes a series of wind patterns known as convection cells. The earth's rotation also alters the airflow pathway, which causes the wind’s path to be curved as it travels between the equator and poles. In the southern hemisphere, winds turn to the left and move anticlockwise around a high-pressure centre, while in the northern hemisphere, winds turn to the right and move clockwise around a high-pressure centre. The twisting of air currents, due to the rotation of the earth is termed as Coriolis effect. Due to this effect, winds turn to the left in the southern hemisphere. In the northern hemisphere, winds turn to the right.
Answer:
<em>The correct option is D) The expression of certain genes is affected by temperature.</em>
Explanation:
There are various factors which control the regulation of a gene. Temperature can be a regulatory factor for certain genes.
Probably, during the warm temperatures, the proteins regulating the fur colour to become reddish brown become activate these genes. As a result, the fur becomes evident.
In the winter, the enzymes controlling the fur might become degraded. A s a result, the genes are not able to express themselves. Hence, a white coat occurs.
The question is incomplete as it does not have the options which are:
- manufactured proteins to be short and defective
- the DNA to break up into thousands of short segments
- incorrect pairing between mRNA codons and amino acids
- no bad effects, as long as the stop codons are not also inserted into tRNA
- all of the above
Answer:
manufactured proteins to be short and defective
Explanation:
The virus particle replicates in the host machinery by using its DNA replication machinery and then transcription and translation machinery.
If by chance, the virus particle inserts stop codon along with the segments of DNA therefore the stop codon will show its effect during the translation process when the DNA sequence is translated into the proteins.
When the stop codon will be read during the translation then the protein synthesis will stop at that time and short or defective proteins will be produced.
Thus, the selected option is correct.
Answer: If a restriction enzyme makes a staggered cut in dna, then <u>Sticky</u> <u>ends</u> are created.
Explanation: Restriction enzyme cut the DNA molecule into fragments. So the Sticky and blunt ends depends how the restriction enzyme cut the DNA.
Staggered cut in the DNA make Sticky ends and Straight cut in the DNA make blunt ends.
large leaves because the larger the leaves are the easier it is for the plant to take in sunlight. plants need sunlight to perform photosynthesis. photosynthesis is when a plant takes in sunlight and turns it into food for itself. plants are considered autotrophs because they can make their own food. hope I helped!:)
