In what nation, where the asian giant tortoise was once thought to be extinct, is a conservationist working to preserve that and three similar species?.

Answers

How is the process of renaturation of species carried out?

In a community in Bangladesh, environmentalists released ten captive-bred Asian giant tortoises to begin the process of renaturation of the species in the country.

Therefore, the renaturalization of endangered species in the wild is the restoration of species through colonies of guarantees, the protection and conservation of animal habitats.

Ceratium fusus is a protist that is found primarily in coastal waters, especially around the coast of the United Kingdom. These organisms are unique because they can undergo a special chemical reaction at night that helps defend them against predators. It provides defense by attracting larger predators that prey on the organisms that eat Ceratium fusus. Which characteristic of Ceratium fusus is being described? photosynthesis glass-like cell walls bioluminescence chitin cell walls.

Answers

A chemical defense mechanism is called bioluminescence.

As mentioned in the reaction, Ceratium fusus undergoes a special chemical reaction at night which helps them defend themselves from predators. During this reaction, light is produced inside a living organism. However, this type of reaction does not produce heat although it does produce light.

What is bioluminescence used for?

The most well-known purpose of bioluminescence is to defend the organism against attacks by predators. This is because the light confuses or frightens predators.

Besides confusing the predator, the light can also alert large predators to approach the location of the organism, in this way this large predator will eat the predator that is threatening the organism which in our question, is Ceratium fusus.

Many marine organisms use the phenomenon of bioluminescence for their defense, in particular marine invertebrates, vertebrates, certain micro-organisms as well as certain fish and fungi.

Hence concluded that the bioluminescence characteristic of Ceratium fusus is being described.

Early hominid fossils were examined and scientists concluded these hominids exhibited bipedalism. How could they tell that by looking at their skeletal remains?

Answers

Answer:

The shape of the thigh bones confirms Orrorin was bipedal. The earliest hominid with the most extensive evidence for bipedalism is the 4.4-million-year-old Ardipithecus ramidus.

Explanation:

Major morphological features diagnostic (i.e., informative) of bipedalism include: the presence of a bicondylar angle, or valgus knee; a more inferiorly placed foramen magnum; the presence of a reduced or nonopposable big toe; a higher arch on the foot; a more posterior orientation of the anterior portion of the iliac

Early hominid fossils were examined and scientists concluded these hominids exhibited bipedalism. This confirms that they belong to Orrorin.


What are Orrorin species?

If dna ligase was nonfunctional, what would be a likely consequence?.

Answers

Answer:

DNA ligase is a specific type of enzyme, a ligase, (EC 6.5.1.1) that facilitates the joining of DNA strands together by catalyzing the formation of a phosphodiester bond. It plays a role in repairing single-strand breaks in duplex DNA in living organisms, but some forms (such as DNA ligase IV) may specifically repair double-strand breaks (i.e. a break in both complementary strands of DNA). Single-strand breaks are repaired by DNA ligase using the complementary strand of the double helix as a template, with DNA ligase creating the final phosphodiester bond to fully repair the DNA.
