Answer:

A. It is easier and more effective to prevent pollution than to clean up and dispose the waste.

Explanation:

Waste disposal would waste more energy, hence making it less efficient than just preventing it. It is also a waste of time. Why disposing waste when you could just prevent pollution? As the wise words say, "Preventing is better than curing."

Hopefully this answer helps you :)

lions [1.4K]

Answer:

(i) Yeast- Kingdom Fungi

(ii) Penicillium- Kingdom Fungi

(iii) Rhizobium- Kingdom Eubacteria

(iv) Mushroom- Kingdom Fungi

(v) Amoeba- Kingdom Protista

(vi) fish- Kingdom Animalia

Explanation:

Living organisms were classified into a large group called KINGDOM, which represent the largest and most generic grouping consisting of organisms that share a few similarities. The kingdoms that living organisms were classified into are as follows: Plantae, Animalia, Fungi, Protista, Eubacteria, Archaebacteria, etc.

Based on the question, the mentioned organisms are classified into the following kingdoms:

(I) Yeast: Yeast is a unicellular microbe classified under the Kingdom Fungi due to possession of chitin in its cell wall and other similar features with members of kingdom Fungi.

ii) Penicillium- Penicillium is a genus classified under the Kingdom Fungi.

(iii) Rhizobium- Rhizobium is a genus of prokaryotic organism (lack membrane-bound nucleus and organnelles) classified under the Kingdom Eubacteria.

(iv) Mushroom- Mushrooms are saprophytic (heterotrophic) species of organisms classified under the Kingdom Fungi.

(v) Amoeba- Amoeba is a genus of unicellular eukaryotes classified under the Kingdom Protista.

(vi) fish- Fishes are organisms classified under the Kingdom Animalia

An earthquake creates a chasm that separates a population of squirrels. The two populations of squirrels evolve into two separat

maksim [4K]

The correct answer is speciation.
Speciation is the term that describes the evolutionary process causing populations to evolve into different species. There are four different types of speciation: allopatric, peripatric, parapatric and sympatric. In this case, the process described is an allopatric speciation, the most common of these four types. Allopatric speciation happens when populations are geographically separated, an event that obstructs the gene flow. Since the gene flow stops, the populations evolve in response to the different environments that they live in.

A 2 L bottle of soda has a volume of 2000 cm³. What is the volume of the bottle in cubic meters?

Svetradugi [14.3K]

Answer:

The answer is

<h2>0.002 cubic meters</h2>

Explanation:

To convert it into m³ we use the following conversion

<h3> $1 {cm}^{3} = 1 \times {10}^{ - 6} {m}^{3}$ </h3>

From the question the value is 2000 cm³

To convert it multiply the value by

1 × 10^- 6m³

That's

<h3> $2000 \times 1 \times {10}^{ - 6} {m}^{3}$ </h3>

We have the final answer as

<h3>0.002 cubic meters</h3>

Hope this helps you

Healthy corals are brightly colored because they _____. healthy corals are brightly colored because they _____. secrete colorful

Korolek [52]

<span>The answer would be: host symbionts with colorful photosynthetic pigments

Coral can host symbionts that will help in their growth. There are algae that could live on the coral surface, giving them some of the energy from photosynthesis and help in calcification while the coral protects the algae. </span>The symbiosis will be formed when nearby algae attach to the corals. A stress on the coral can cause the algae to eject the algae.
