Answer: A virus lack the metabolic machinery common to other microorganisms

Explanation:

A virus is an ultramicroscopic particle capable of causing disease. It differs from other disease-causing organisms like bacteria, nematodes etc, because it has no metabolic system of its own but relies on its host system for survival and replication.

Hence, it is difficult for antibiotics to target and destroy viruses without harming patients, rather antiviral drug are prescribed against viruses

Answer: Due to structural differences between virus and bacteria, antibiotics can't treat viral infections.

Explanation:

Viruses insert their genetic material into a human cell's DNA in order to reproduce. Antibiotics cannot kill viruses because bacteria and viruses have different mechanisms and machinery to survive and replicate. The antibiotic has no “target” to attack in a virus and therefore can't kill a virus.

Would you expect a shrub or dandelion (dispersed by wind-blown seed) to be a more likely pioneer plant species? why? Thank you s

S_A_V [24]

Answer:

Dandelions may appear quicker after harsh conditions and reproduce at a faster rate. However, both dandelions and shrubs are considered fast-growing plant species that can be categorized as pioneer species.

Explanation:

Secondary succession refers to the changes that take place in a disturbed habitat. Pioneer plant species are those that colonize new habitats after harsh climate conditions and that tend to reproduce at a fast rate.

According to researcher J.W. Darlling (2008), pioneer herbs and shrubs are species that tend to grow faster in comparison to other species, making them excellent pioneer species.

This occurs thanks to plants that are wind-pollinated, such as dandelions, have a higher chance to appear because, as it is a disturbed environment, there are no insects or other fauna present. In addition, shrubs are persistent species that are able to reproduce fast with limited soil availability but a bit slower in comparison to dandelions.

Scientists are worried about the future of some species that have experienced extreme decreases in both population size and gene

prisoha [69]

Answer:

Scientist are worried about the future of some animals because their number and genetic diversity both is very low.

Genetic variation in the organism of the same species or different species provides the stability for the survival.

Even if the number of organism increases its stability will be low because the genetic variation of those organism is low.

So, even after their number increases they can die due to less variability so genetic variation is equally important as like that of population size.
