Answer:
Natural Selection
Explanation:
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?.
In Bangladesh, the Asian giant tortoise was once considered extinct, but through environmental conservation practices, there are efforts to preserve and renaturalize the giant tortoise and tortoises.
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.

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

What is important in Hubble's discovery about the red shift in the spectra of galaxies? a. It proves the Big Bang theory. b. It suggests the existence of black holes. C. It suggests that the universe is expanding. d. It suggests that the universe is contracting.
Answer:
c
Explanation:
Hubble's brilliant observation was that the red shift of galaxies was directly proportional to the distance of the galaxy from earth. That meant that things farther away from Earth were moving away faster. In other words, the universe must be expanding.
Early hominid fossils were examined and scientists concluded these hominids exhibited bipedalism. How could they tell that by looking at their skeletal remains?
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.
The shape of the thigh bones of the hominid fossil confirms that it belongs to Orrorin species which was bipedal. The earliest of the hominid fossils with the most extensive evidence for bipedalism is almost about 4.4 million year old Ardipithecus ramidus.
Major morphological features which are diagnostic or informative of bipedalism in the species include the presence of a bicondylar angle, or the valgus knee. It is a more inferiorly placed foramen magnum and is the presence of a reduced or the non-opposable big toes. A higher than normal arch on the foot and a more posterior orientation of the anterior portion of the iliac

Which of the following are environmental benefits of green roofs? Select the two correct answers
1. Green roofs can reduce electricity bills
2. Green roofs can improve air quality
3. Green roofs can absorb storm water and can release it slowly
4. Green roofs tend to increase number of roofing jobs
5. Green roofs are easy to install and maintain
Answer:
Explanation:
Enhanced stormwater management and water quality: Green roofs can reduce and slow stormwater runoff in the urban environment, and also filter pollutants from rainfall. Green roofs can retain nearly all storm-related precipitation during the summer months, with lower retention during the winter months (< 20%).
The benefits of green roofs are green roofs can improve air quality, they can absorb stormwater, and can release it slowly. The correct options are 2. and 3.
What are green roofs?A flat or slightly inclined roof may have a layer of flora grown on top of a waterproofing system, known as a "green roof." Vegetative or eco-roofs are other names for green roofs.
Extensive, intensive, and semi-intensive are the three basic subcategories. Improved stormwater management and water quality: Green roofs may filter pollutants from rain and minimize and slow stormwater runoff in metropolitan areas.
Nearly all storm-related precipitation can be captured by green roofs in the summer, but less so in the winter.
Therefore, the correct options are 2. Green roofs can improve air quality.
3. Green roofs can absorb stormwater and can release it slowly.

How does pollution affect air, water and land resources?
Answer:
Here are some effects
Due to release of heavy harmful gases like carbon dioxide the air is polluted.By which people are affected by lungs diseases .The global warming occurs.This pollution leds to acid rain which mixes up with water and pollutes itIt also decreases the productivity of land .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.
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.

How does competition drive natural selection?
Answer:
Competition often occurs between members of the same species. This is called intraspecific competition. This is the type of competition that is the driving force behind natural selection within a species. Competition influences natural selection by the finite amount of resources available, those members of species best adapted to take advantage of the resources are more likely to reproduce and pass on their genes to the next generation.
