how are marine iguana and land iguana are similar? how are they different?​
PLS HELP

Answers

Answer:

The marine iguana is the only lizard in the world with the ability to live and forage at sea and is endemic to the Galapagos Archipelago. There are eleven very similar subspecies, found on different islands, with those from Isabela and Fernandina being the largest. The adults are black for most of the year, however the males change colour during the mating season – with different subspecies adopting different colourations. Near Española and Floreana they are most colourful – turning bright green and red; on Santa Cruz they are red and black; and on Fernandina they become dull green and brick red. The juveniles are generally black, with a lighter dorsal stripe than the adults. During the mating season males fight for dominance over harems of females, which they will fiercely defend from rival males.

Marine iguanas are not a very agile species on land, but they are excellent swimmers – moving easily through the water as they feed on algae. Larger individuals go further out to sea and use their powerful claws to grip on to rocks in strong currents to feed, whilst the smaller ones stay inshore near rock pools, feeding on algae exposed at low tide. Due to the high concentration of salt in their diet, marine iguanas filter their blood at the nose and sneeze out the excess salt, often forming salt crystals on the snout.

Despite not being truly social, iguanas are highly gregarious – especially on cold nights when they tend to group together to conserve heat. In the morning, they bask in the sun, absorbing heat with their black scales until they have enough energy to swim out to sea to forage. Upon entering the water, their heartbeat slows to half its normal pace in order to conserve energy and allow them to feed for as long as possible.

In Galapagos

Where to see them: They can be seen in coastal regions on the islands of Isabela, Fernandina, Española, Floreana, Santa Cruz and other islets around them.

When to see them: They live on the islands all year round, with the mating season occurring between January and March. They are active during the day and spend a lot of time on rocks basking in the sun.

Threats: The introduction of cats and dogs by humans has greatly affected the numbers of marine iguanas as they predate upon the juveniles, which are poorly adapted to defending themselves against large land predators. El Niño periodically decreases the iguana population (by up to 85%), as it cuts short their food supplies. Oil spills may also have similarly dramatic effects on the population. They could also be threatened by marine plastic pollution – specifically microplastics.

Conservation: The marine iguana is protected under Ecuadorian law and is listed under CITES Appendix II. Currently, we are working with partners to assess the risk of marine plastic pollution to marine iguanas as part of our Plastic Pollution Free Galapagos programme. GCT has funded a research project investigating the population dynamics of the marine iguanas on San Cristobal as there may in fact be more than one species of marine iguana present on the

Explanation:

Unlike land lizards, marine iguanas have blunt snouts that help them feed on algae underwater. They also have flattened tails that help them swim efficiently. 4. Marine iguanas typically spend only a few minutes underwater eating but can spend up to 30 minutes at a time submerged.

Which individuals would be at a disadvantage in an area with high prevalence of malaria?.

Answers

The individuals who have purebred dominant genotype would be at a disadvantage in an area with a high prevalence of malaria.

What do you mean by Malaria?

Malaria may be defined as a disease that is caused by the plasmodium parasite and may spread to the people through the bites of a female mosquito Anopheles.

Those individuals who have the genotype purebred dominant (AA) produce normal red blood cells, while the individual who has the genotype purebred recessive (aa) possess sickle cell condition. The normal red blood cells are immaculate hosts for the infection of malaria.

Therefore, the individuals who have purebred dominant genotype would be at a disadvantage in an area with a high prevalence of malaria.

The Coriolis effect is named after Gaspard Gustave de Coriolis (1792–1843), who provided the first mathematical explanation for this apparent deflection of motion off a straight line in a rotating coordinate system.

What is coriolis effect?

The Coriolis effect depicts the pattern of deflection experienced by objects traveling great distances around Earth without being firmly linked to the ground.

Several significant large-scale weather patterns are caused by the Coriolis effect. Earth's rotation is crucial to understanding the Coriolis effect. Particularly, Earth rotates more quickly at the Equator than at the poles.

Because Earth is wider towards the Equator, equatorial regions rotate at a speed of around 1,600 kilometers (1,000 miles) per hour in a 24-hour period. Earth rotates slowly toward the poles, at 0.00008 kilometers per hour.

Therefore, The Coriolis effect is named after Gaspard Gustave de Coriolis (1792–1843), who provided the first mathematical explanation for this apparent deflection of motion off a straight line in a rotating coordinate system.
