Answer:
The correct answer is option a-"oceanic lowstand".
Explanation:
An oceanic lowstand is defined as a geological phenomenon at which the sea level is at a low point and the continents are mostly emergent. The Earth has been on onceanic lowstands historically. This has been identified by different evidence, including the Gulf Coast rivers formation of braided channels.
Answer:
A
Explanation:
According to this hypothesis that pillar coral digested zooxanthellae, the coral digested zooxanthellae inside the pillar coral must be dead. If anything is engulfed then it should be first dead inside the body of the predator and then the energy is extracted from the food. The food eaten serves as a source of energy.
Sunlight help to provide energy to the plant to complete the process. Basically, the plant harvest the solar energy.
During DNA Replication, the DNA strand that has the bases 3'ATACGC5' produces a strand with the bases 5'TATGCG3'
Answer: Option B
<u>Explanation:</u>
The DNA Replication produces the newly formed two complimentary base pair strand from the two template base pair strand, so basically the already existing DNA strand is replicated, in order to produce complimentary DNA strand, with the template giving one strand to new each.
Thereby, here the given base was 3' ATACGC 5' so the first thing to produce the strand will be that the coding end will be reversed so the 3' end will have 5' end and 5' end will have 3' end. Then A bonds with T and T bonds with A and, so C bonds with G and G bonds with C, therefore, ATACGC will produce TATGCG. Thereby, answer would be 5'TATGCG3'.
Answer:
Firstly, the partial pressure of nitrogen (78%) is crucial to breathing purposes. Without this pressure, the lungs will burst and animals cannot survive.
Secondly, nitrogen is required for the formation of amino acids (building blocks of proteins) and other organic compounds that are necessary for the survival of living organisms. Principally, in the atmosphere, nitrogen is present in the form of molecular nitrogen (N2). N2 is fixed by nitrogen-fixing bacteria that form nitrates and nitrites. These molecules are then used in biochemical processes to produce proteins (amino acids) and other organic compounds. In the absence of nitrogen, these processes could become seize of limited significantly thus affecting life overall.
Thirdly, nitrogen and its derivatives act as greenhouse gases that maintain the Earth's temperature within a range that supports life. Yes, the increased abundance of nitrous oxides is not good because of acid rain and other issues, however, still, the presence of nitrogen is important for life on this planet.
