Answer:

The correct answer will be- swamps and clouds

Explanation:

Biology is the major field of science which deals with the study of living things present on the Earth and a person who studies biology is known as Biologist.

In the given question since the animal and plants are the living organisms which exhibits the characteristic of life-like cellular organization, metabolism, reproduction and heredity material are studied by the biologist.  Since swamps and clouds do not exhibit the characteristics of the living organisms therefore they are not studied by the biologist.

Thus, swamps and clouds are the correct answer.

The diagram represents a model of how bacteria become resistant to an antibiotic, allowing bacteria to survive treatment. Which
Stella [2.4K]

Answer:

A

Explanation:

Genetic mutations randomly occur in the population of cells. If, by chance, there is a mutation that gives the bacterial cell resistance to an antibiotic, then that mutation will remain in the population.

This is because it gives the cell a competitive advantage (because it is more likely to survive than its non-resistant counterparts). If it survives, it will divide and pass the mutation on to its daughter cells, which will survive. This keeps happening until an entire population will carry the mutation.

Describe the manner in which you would determine how long ago two species of bacteria diverged from one another.
Andrei [34K]

Answer:

One of the probable ways to determine how long ago any two species of bacteria diverged from each other is by drawing a phylogenetic tree.

Explanation:

  • Phylogenetic tree are trees that show the ancestry of two species of interest and the relationship between them.
  • The idea behind the construction of phylogenetic tree is darwins's "descent with modification theory".
  • A phylogenetic tree is constructed using the similarities or differences in either physical characteristics, behavorial, or genetic buildup.
  • Derived traits shared between the different species are the actual data used to construct a phylogenetic tree.

4. In humans and all creatures constructed of eukaryotic cells, the DNA always resides in the .
Lady_Fox [76]

Answer:

Nucleus (as nuclear DNA),mitochondrial(mitochondrial DNA) and chloroplasts.

DNA is packed tightly around protein called Histones, in Eukaryotes cells;so that many molecules can easily be held together as chromosomes.

Chromosomes are thread-like structure in nucleus of cells.The histones provide support to the DNA molecule

The part DNA molecule coded for by a polypeptide is GENE, therefore  in the nucleus of cells, DNA contains GENE,and the gene and DNA are packed in chromosomes,DNA appears as circular DNA mitochondria

How much energy does nuclear fusion generate
Pavlova-9 [17]

4. E=mc²

Explanation:

The best approximation of the energy released during a nuclear fusion process can best be determined using the Einstein equation.

  In nuclear reactions, mass and energy are equivalent:

            E = mc²

 E is the energy

  m is the mass

  c is the speed of light

  • In nuclear reactions, some of the mass is converted into the energy.
  • Therefore mass is not conserved in such equations.
  • This is why they release huge amount of energy.
  • From this equation, we know that the more mass loss, the more the energy that would be produced.
  • In a fusion reaction, two light nuclei combines to form a heavier one.
