I believe the correct answer would be “Viruses are unicellular.”
The roles fulfilled by the males increase the survival of the species is males scare off predators and protect the pack.
<h3>What does fittest animals mean?</h3>
According to natural selection, there is a constant struggle for survival and only the fittest organisms are selected. These fitter organisms would be able to pass on their advantageous traits to their descendants.
Generally the main factors that cause the destruction of a habitat are deforestation, fires, livestock, agriculture and human occupation. Don't stop now.

Answer:
glucose
Explanation:
Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants ([Figure 4]). After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose.
<h2>Gelatin </h2>
Explanation:
Gelatin is a differential medium which tests the ability of an organism to produce an exoenzyme, called gelatinase (this enzyme hydrolyzes gelatin)
When gelatin is at a temperature below 32°C (or within a few degrees thereof), it is a semisolid material and at temperatures above 32°C, it is a viscous liquid
When gelatin is broken down, it can no longer solidify and if an organism can break down gelatin, the areas where the organism has grown will remain liquid even if the gelatin is refrigerated
No the conclusion by student is not right because the tube must be runny after incubation followed by refrigeration to be considered gelatinase positive
Answer:
Molecular, Microscopic, Cell, Tissue and Organ levels
Explanation:
The natural strength production needed for skeletal muscle to function occurs at the molecular level. You can develop a better knowledge of the properties of cells and tissues by simply studying the molecular systems common to the cells in question. The different muscular level down to myofilaments are:
-
Molecular level — actin and myosin
- Microscopic level — sarcomere and myofibrils
- Cell level — myoblasts and myofibers
- Tissue level — neuromuscular intersections and fascicles
- Organ level — The key skeletal muscles of the body
