Answer 1

Answer:

1. The right answer is gymnosperm.

The term gymnosperm comes from the Greek gumnospermos meaning "bare seed". It refers to plants that are part of a subphylum of spermaphytes, seed plants. The hallmark of gymnosperm plants is that their ovum is bare (not enclosed in an ovary unlike angiosperms) and receives pollen directly. It is carried by a fertile leaf or scales more or less open.

2. The right answer is A.

Angiosperms are plants whose reproductive organs are condensed into a flower and whose fertilized seeds are enclosed in a fruit, unlike gymnosperms whose seed is bare. Thus, angiosperms are commonly called "flowering plants".

3. The right answer is C

A fern designates a filicophyte, a pteridophytic plant vascularized without flower or seed, consisting of a rhizome producing aerial stems whose large fronds, equivalent to the leaves, bear sporangia on their underside.

By definition, a fern is a cryptogam belonging to a group of about 12,000 species of vascular plants that reproduce by spores and have no seeds or flowers.

4. The right answer is seeds.

Spermaphytes (which include gymnosperms, chlamydosperms, and angiosperms) are the first seed plants to appear on the surface of the globe. They are distinguished from other plants (bryophytes and pteridophytes), among others, by aerial reproduction via pollen.

Why are many ecological phenomena difficult to study

Answers

Because ecosystems are densely interwoven spaces with numerous individuals who have complex relationships to one another, many ecological phenomena are challenging to analyze.

What is ecological phenomena?

When ecological phenomena are arranged into hierarchies, it is frequently possible to create models that simultaneously include impacts from many measurement scales.

This method has been successfully used, for instance, to analyze food webs, where trophic levels correlate to levels in the hierarchy.

Since the temporal dynamics of predators, prey, and herbivores often resolve over comparable amounts of time, measuring the dynamical features of food webs can theoretically be done at the same scale.

Because ecosystems are complex, interconnected systems with numerous players and linkages between them, many ecological phenomena are challenging to analyze.

Therefore, many ecological phenomena difficult to study.

Many ecological phenomena are difficult to study because they can take long periods of time or have large spatial scales.

Animals takes in this oxygen and release it as (blank)?

Answers

Animals take in this oxygen and release it as carbon dioxide. It is the process of respiration that helps the animals to survive. Actually the oxygen is transferred to the blood and the cells and then the carbon oxide is transferred from the blood and cells to the lungs for breathing out. Carbon dioxide is a waste material for our body. The build up of carbon dioxide in the body can be very fatal and lead to death of the animal. It is actually the reverse in case of plants. Plants take in carbon dioxide for making food by the process of photosynthesis and gives out oxygen. So it is a balancing act between animals and plants.

Conservation efforts

It is true that conservation efforts have resulted in restoration of some wildlife habitats. Since some animals, over the change of time and of human’s abusive efforts, could no longer live, the governmental an non-governmental organizations and volunteers are now doing ways to alleviate the said problem and so far it has been effective as som species close to extinction was saved (e.g. platypus).

How have humans contributed to the increase in earthquake activity?

Answers

Humans had contributed to the increase in earthquake activity by building dams and reservoirs, extracting water from underground, and building geothermal power plants.

Yes. We drill into the earth to mine for gas, oil and minerals and construct massive dams and, as a result, have caused at least 200 quakes of more than 4.5 magnitude in the past 160 years, says Christian Klose, a researcher at Columbia University who studies man-made quakes.The best-known case is the earthquake caused by the Zipingpu Dam, in China's Sichuan province, in 2008. Zipingpu held 42.3 billion cubic feet of water, the weight of which precipitated what Klose says is the largest human-triggered earthquake to date: a 7.9-magnitude quake that killed nearly 80,000 people. Klose estimates that Zipingpu, with nearly 320 million tons of water pressing down on a fault line, contributed enough stress to trigger the quake through a process called impoundment. "If you push your finger on top of a paper plate, the plate will bend," he says. "That same effect works on all the tectonic plates on the Earth's crust." The quake occurred two years after the dam's completion, and its epicenter was a mere three miles from the structure.Authorities in Basel, Switzerland, shut down the city's geothermal plant after a 3.4 quake in 2006. Tapping geothermal energy involves boring into rock miles beneath the Earth's crust in search of steam as a source of energy. Engineers in areas without much water, such as Basel, sometimes create boreholes by way of hydraulic fracturing, or "fracking," which involves forcefully injecting water to create fissures. Fracking can generate small tremors, but the real damage may happen as excess liquid pools in the cracks between rocks, making them less stable. Although dams have caused some 76 earthquakes, mining is responsible for at least 137 earthquakes, over half the number of man-made quakes to date.In 1989 a 5.6-magnitude earthquake hit Newcastle, Australia, the direct result of coal mining. Extracting millions of tons of coal added stress to the fault lines, but the real danger resulted from the water that was extracted during mining. For each ton of coal produced, Klose estimates, 4.3 times as much water was pumped out of the ground, a necessary step to prevent flooding inside the mine. But removing so much water dramatically altered the stability of the earth surrounding the mine. Klose says the earthquake caused $3.5 billion in damage—an amount that nearly equaled the profit of all the coal produced by the mine over its 200-year history.

Which is not a part of an organism’s environment?ancestry

vegetation
air quality

Answers

Correct answer: A). Ancestry

The environment includes everything that is found around us. It may be living or non-living. It involves chemical, physical and natural forces. The living organism lives in the environment and they continuously interact with each other and may adopt their-self according to the environment they live.

Ancestor is those from whom a person is descended, it may be on the father side or mothers side, a forefather.

Hence, ancestry is not a part of organisms environment.
