Answer:
Option-4
Explanation:
Cow milk allergy or the cow milk protein allergy occurs when the allergy is caused by the proteins of the cow' milk when provided to the infant baby during the first 6 months.
The allergy is caused when the immune system of the infants consider the proteins of the cow milk as a foreign substance or antigens. These antigens activate the immune response which releases the chemicals and infant develop the symptoms of allergy.
Thus, option-4 is the correct answer.
Explanation:
Abiotic processes in the carbon cycles : Management of the carbon cycle is the focus of global warming. Respiration, deforestation, burning of fossil fuels, and forest fires are processes that put CO2 up in the atmosphere. Organisms eat plants, which is comprised of carbohydrates come from CO2 in the atmosphere.
Because natural selection can only increase or decrease frequency of alleles that already exist in the population
Answer: Option B) phosphate; hydroxyl; 3'
We identify nucleic acid strand orientation on the basis of important chemical functional groups. These are the phosphate group attached to the 5' carbon atom of the sugar portion of a nucleotide and the hydroxyl group attached to the 3'
carbon atom
Explanation:
For both RNA and DNA, chemical groups such as phosphate (PO3-) attaches to the 5' carbon of the pentose sugar (deoxyribose in DNA, ribose in RNA).
While hydroxyl group (OH) attaches to the 3' carbon atom of the pentose sugar.
Thus, a nucleic acid structure structure reveals a several repeating units of nucleotides where nitrogenous base links to a pentose sugar, who in turns is linked to phosphate group
Image result for how does vascular system serve the needs of plant cells
Xylem and phloem make up the big transportation system of vascular plants. As you get bigger, it is more difficult to transport nutrients, water, and sugars around your body. ... The bottom is a system of roots. Each needs the other to survive.
