Streptococcus pyrogenes : Round (or) Ovoid
Paenibaccilus polymyxa:
Aquaspirillum bengal: Helical
Explanation:
- Streptococcus pyogenes are gram positive, Round shaped, Anaerobic growth bacteria, Non-motile bacteria.
- Aquaspirillum bengal is helical in shape with its composition of deoxyribonucleic acid and cytosine. It is Gram negative and chemo-organotrophic. It is also motile with the help of flagella.
- Paenibacillus polymyxa is also known as Bacillus polymyxa which is capable of fixing nitrogen. It is found in soil, plant tissues and marine sediments. It has a major role in forest ecosystems and potential future applications as a biofertilizer and biocontrol agent in agriculture.
Answer: B. The number of individuals that a habitat can sustain with the resources that it has available.
Explanation:
A carrying capacity is the number of individuals of the population belonging to a particular species that an habitat or region or ecosystem can support or sustain in terms of providing the resources. If the population exceeds over the carrying capacity then this results in decline in members of the population.
According to the above description the accurate definition of carrying capacity is B.
Answer:
Evolution is a change in the inheritable phenotypic characters within a population occurs through successive generations.
Explanation:
Evolution is a change in inheritable characters of population during a period of time by means of natural selection. These changes in phenotypic characters brings the formation of new species. Darwin's theory consists of three categories,individuals within a group are variables, variations are inheritable,all individuals with variables survive.
According to Darwin's theory states that survival is based on selective mode like particular phenotypic characteristics or behavior given to some individuals who are able to survive in a particular environment.
The answer is budding. IN this type of asexual reproduction,
the offspring are genetically identical
to the parent. Examples of an organism that
reproduces by budding include hydra,
starfish, corals, and sponges. Yeast, fungi, also reproduce
asexually by budding.
Answer:
<em>In order to reach equilibrium, water will move outside the cell to reach equilibrium. </em>A cell tends to lose or gain water in order to reach equilibrium.
If there are more number of solutes outside the cell, then the water will move out of the cell in order to maintain equilibrium. On the other hand, if there are more number of solutes inside the cell then the water will move inside the cell to maintain equilibrium.
