A spectroscope
Explanation:
The color of the light emitted by her flashlight can best be studied using a spectroscope.
Spectroscope is an instrument used to observe the light emitted by a substance.
Just like a prism, it splits up light using its different wavelengths.
The light entering the scope is split into its different component parts.

Answer:
A. The algae are heterotrophs
Explanation:
Algae which are heterotrophic obtain nutrients from complex organic substances. Thus, this type of algae is a consumer. This is in contrast to autotrophs, which form their own organic substances from simple inorganic substances. They produce their own energy
The diammonium phosphate which run off until the lake nourish these algae and make them grow without limit.
In multicellular organisms individual cells grow and then divide via a process called mitosis, thereby allowing the organism to grow. Cellular division and differentiation produce and maintain a complex organism, composed of systems of tissues and organs that work together to meet the needs of the whole organism.
Answer:
The correct option is A, since if the DNA enters in a circular form it is called a plasmid, and the plasmids upon entering the bacteria self-replicate outside the genetic structure, which gives the bacteria better survival qualities.
Explanation:
Plasmids are generally circular extrachromosomal DNA molecules that replicate and transmit independently of chromosomal DNA, and are normally present in bacteria, archaea, and sometimes in eukaryotic organisms such as yeast. Its size varies from 3 to 10 kb. The number of plasmids can vary, depending on their type, from a single copy to a few hundred per cell. Plasmid vectors allow cloning of exogenous DNA ligands of up to 4 kb since a larger size than this makes cloning in these vectors difficult. The term plasmid was first introduced by the American molecular biologist Joshua Lederberg in 1952. Plasmids can only coexist as one or more copies in each bacterium, due to cell division they can be lost in one of the secreted bacteria.
a nitrogenous base, a sugar, and a phosphate. A nucleotide is the basic subunit of both DNA bad RNA. It contains a base with nitrogen, a 5-carbon sugar and a phosphate group.
