The sequence of sub units in a protein is most directly dependent on the DNA in the chromosomes in a cell
Answer: Option B
<u>Explanation:</u>
Any life events that takes place in a cell depends upon the central dogma of life that is the DNA getting transcribed into RNA and the RNA getting translated into protein, therefore we can conclude that the sequences of amino acids are based on the sequences of DNA that are present inside the chromosomes that are packed in a nucleus of a cell.
For a person with blood type A- (A negative), they can be transfused with either blood type A negative , or blood type O negative.
This is because any other blood type will immediately be rejected by their body.
A person with blood type A negative has got antibodies against any other blood type which has a rhesus positive factor as well as antibodies against any other blood type of a different group such as B and AB, even if they are rhesus negative.
Therefore because of the rhesus negative factor, a person with blood type A negative can only be transfused with rhesus negative .
True because how else would we survive on Earth?
Answer:
epiphytic roots
Explanation:
Epiphytic roots are those that live on other plants without parasitism. In this relationship, the epiphyte uses the other vegetable only as a support (phorophyte), removing no nutrients and, consequently, causing no harm to the species.
Epiphyte roots are estimated to represent about 10% of the total amount of vascular plants on the planet. This means that there are on average 29,000 plant species with this peculiar habit of life. These vegetables are mainly found in tropical rainforests and have almost no representatives in places with very low temperatures.
Answer:
Supports a larger number of plant species and, therefore, a greater variety of crops. Protect freshwater resources. Promote soils formation and protection. Provide for nutrient storage and recycling.
