The shoreline is one of the harshest and most changeable environments for living creatures. The changing tides shift the environment dramatically within a sub-daily cycle. Here, we can consider two typical shoreline organisms, and the changing environment they must endure. Within the rocky shore environment, an octopus would be within the shallow but open sea environment during high tide, and water temperature and salinity conditions would be fairly constant. During low tide, the octopus might become trapped in a rock pool. This environment is dramatically different. The water temperature and salinity might increase drastically with exposure to solar radiation. The octopus is also more vulnerable to predation by humans and other land animals. Within the sandy shore environment, sand clams would be actively positioned at the interface of the sand and water, and will be actively filtering sea water for detritus. During low tide, the sand would be exposed to the air, and the clams would burrow down into the sand so as to avoid dessication.
Answer:
Answer: The correct option is C
Explanation:
The glycolytic pathway involves the oxidation of glyceraldehyde 3-phosphate.
Glyceraldehyde 3-Phosphate is oxidized by NAD+ and an inorganic phosphate is incorporated into the product to form an acyl-phosphate, 1,3-bisphosglycerate, which is an energy rich intermediate. NAD+ is reduced by the transfer of an hydride ion to form NADH. Once NADH is formed, its affinity for the enzyme decreases so that the free NAD+ displaces this NADH. The energy released by the oxidation of the substrate is conserved in the terminal phosphoanhydride bond of ATP via the formation of high energy intermediates.
Thus the oxidation/reduction is necessary to produce NADP which is required for ATP synthesis.
The answer is Heredity! :)
The name of the tear collecting structure under the skin near the bridge of the nose is the lacrimal sac. The lacrimal sac is part of the lacrimal drainage system or the lacrimal apparatus. The tears are produced in the lacrimal gland and will drain through a hole near the lower palpebral conjuntiva called the puncta which serves as the entrance in the lacrimal system. The tears will now enter the canalicula which serves as the passage way from the puncta to the lacrimal sac. Lastly, the tears in the lacrimal sac will drain to the nasolacrimal duct and to the nose. This also explains why we get runny nose when we are crying.
Answer:
Meiosis II.
Explanation:
Meiosis may be defined as a type of cell division in which four daughter haploid cells are produced from the single diploid cell. Meiosis is also known as reduction division as the chromosome number is reduced to half as compared with the original parent cell.
Meiosis is divided into meiosis I and meiosis II. The meiosis is similar to mitosis as the each cells contain only one set of the homologous chromosomes.
Thus, the correct answer is option (3).
