In 1973, Stanley Cohen and Herbert Boyer inserted a gene from an African clawed frog into a bacterium. The bacterium then began producing a protein directed by the gene from the frog.
Which is considered a transgenic organism?

Answers

Answer 1

Since the bacterium expresses the foreign gene from the African clawed frog, therefore, the bacterium is considered as the transgenic organism.  

Gene is the most basic unit of heredity. It is the segment of DNA that encodes for a particular protein. There are various genes present in a single DNA strand. The genes are further composed of alternative forms called the alleles.

Transgenic refers to the phenomenon where DNA segment from an unrelated organism is artificially introduced and expressed in the host's genetic machinery. Such an organism is called the transgenic organism. And the artificially introduced gene is called transgene.

How long can killer whales go without air?

Answers

Killer whales can't even come close to holding their breath for as long. Their maximum duration is approximately 15 minutes, but we typically observe them surfacing for air every 3-5 minutes when traveling or every minute when moving quickly.

The largest member of the Dolphin family, the orca, also known as the "killer whale," is a whale with teeth. The black-and-white coloration, large dorsal fin, and streamlined body of these large marine mammals make them easy to spot. Bright white dominates on the fluke undersides, ventral surface, and lower jaw. When they are looking for food, the distinctive patterns serve as a form of camouflage to conceal their presence.

Like humans, whales use their lungs to get the oxygen they need from air. However, instead of breathing through their mouths, they breathe through the blowholes on top of their heads, which are their nostrils. Without having to lift their entire head out of the water, they can easily breathe through the blowhole.

Five islands, A, B, C, D, and E, differ only in distance from the mainland, area, and species diversity. Which island would be predicted to have the highest species diversity ?O AO BO CO DO E

Answers

Island B is the most likely to have the highest species diversity out of the five islands. The larger area and closer proximity to the mainland provide more opportunities for species to survive and thrive on island B.

This increases the potential for a greater diversity of species, making island B the best candidate for the island with the highest species diversity.The island with the highest species diversity will likely be island B due to its larger area and relatively close distance from the mainland.

Island B is located 50 kilometers from the mainland, while islands A, C, D, and E are located at 50, 500, 1000, and 1000 kilometers away, respectively. Furthermore, island B is 1 x 106 hectares in size, much larger than Islands A, C, and D, which are 1 x 102 hectares in size.

The larger area of island B provides more habitat for species to survive and thrive, while the closer distance from the mainland increases the chances of species dispersing to the island. As species are able to move more freely and find suitable habitat in island B, island B is likely to have a higher species diversity in comparison to Islands A, C, D, and E.

Habitat fragmentation can also impact species diversity, and the distance from the mainland may further influence species diversity by reducing the exchange of individuals between mainland and the island. Thus, island B has the highest potential for species diversity due to its larger area and closer distance from the mainland.

The electrical stimulation of the cardiac muscle cells is called depolarization; the mechanical contraction is called Systole.

During systole, the 2 ventricles broaden strain and eject blood into the pulmonary artery and aorta. At this time the atrioventricular valves are closed and the semilunar valves are open. The semilunar valves are closed and the atrioventriular valves are open at some point of diastole. The cardiac cycle is basically cut up into phases, systole (the contraction phase) and diastole (the rest phase). Each of those is then similarly divided into an atrial and ventricular component.

What is Mendel's second conclusion?

Answers

Mendel's second law, also known as the Law of Segregation, states that during the formation of gametes,  two copies of each gene (alleles) separate from each other and are passed on to different gametes independently of one another.

This means that for each inherited trait, an organism receives one allele from each parent, and the allele that is expressed (determines the phenotype) is determined by its dominance. This means that the dominant allele will mask the effect of the recessive allele. This law explains the phenomenon of Mendel's first law, the law of dominance, which states that certain traits are dominant over others. Mendel's second law also explains the phenomenon of Mendel's third law, the law of independent assortment, which states that the inheritance of one trait is independent of the inheritance of another trait.
