Answer:
True
Explanation:
Development, together with globalization, drove severe changes at a global level. The natural and original environments suffered from these effects and still are.
Human beings have constantly been altering the natural ecosystems and causing irreparable damages to nature. For many decades, development involved society and technology advance over new areas unpopulated by humans.
<u>Some</u> of the principal human activities responsible for biodiversity loss are
- the uncontrolled use of unrenewable resources,
- overexploitation of renewable resources;
- land destruction for the mining industry, farming and cattle industry, buildings, and other infrastructures;
- the unplanned advance of cities, and opening of new roads to connect those cities.
All of them involving
- deforestation and fragmentation of natural landscapes;
- water, air, and soil pollution,
- species loss, and reduction of biodiversity.
With globalization, transport around the world became normal. And when traveling around the world, new species are intentionally or unintentionally transported too. When these species, of animal or vegetable origin, get established in a new area, they overgrow to the point of turning invasive.
Invasive species are uncontrollable and cause severe damage in native endemic species by competing for resources. The whole ecosystem structure changes.
But there are some background glitches in the system that are the principal responsible for all the mentioned activities. Some important aspects are lacking
- The respect for nature,
- People´s education at different levels to care and protect wildlife,
- Interest in keeping ancestral knowledge,
- Planning and previous environmental impact studies,
- Policies to control human activities,
- Caring involved government.
If, as a society, we lack these aspects, the possibilities of changing our impact on nature are far away.
Answer:
Contraction.
Explanation:
Muscle tissues are defined as they are elastic and extensible in nature. In other words it's also defined as they are able to stretched and returned to its original size and shapes. A unique feature of muscle tissue is they are able of contractile in nature. With the help of this contraction they are able to sliding myosin and actin filaments which are present in muscles tissues.
Basically muscle tissues are three types:
1) Skeletal muscle: They are strong and rapid in contraction.
2) Cardiac muscle: They are strong in contraction.
3) Smooth muscle tissues: They are slow and weak in contraction.
Answer:
Chloroplasts are what give plants their green color. The second major difference between plant and animal cells is the cell wall. While both plant and animal cells have a cell membrane, on plants have a cell wall.
Answer:
C). Argument; conclusion: Classification,...a method of understanding evolution.
Explanation:
An argument is characterized as 'a series of propositions organized so that the final proposition is a conclusion that is intended to follow logically from the previous propositions.' The given passage exemplifies an argument as it puts forward a claim that can be argued upon if it is true or not and supported through adequate reasoning. <u>The factual evidences are provided to support the validity of the proposition and the conclusion that 'classification initially a process...understanding evolution' is compelled</u>. Thus, <u>option C</u> is the correct answer.
