The phase contrast image lets us see the bacteria in a clearer form with defined shades of cell organelles with the difference in the brightness. Here the image is clearly visible even without staining.

Where as without staining, the appearance of bacteria in the bright field mode only shows bright structure and not the color contrasts.

Which fungus does contain mycelium?​
Sergeu [11.5K]

Answer:

Mycelium is part of the fungi kingdom and is the network of threads, called hyphae, from which mushrooms grow. Not all mycelia fruit mushrooms, depending on the environmental conditions, but all mushrooms come from mycelia.

A biologist studying a desert ecosystem observes that the population of a lizard species increases following a particularly hot,
bekas [8.4K]
Based on the description of events, being that the lizard population appears to increase as soon as the snake population decreases, it appears that the snakes prey on the lizards. This suggests that the snake is a keystone species. A keystone species is one that has a dramatic effect on maintaining the balance of an ecosystem. As soon as the snake population decreases, major changes occur to the ecosystem, such as the lizard population increasing.

Therefore, the answer is D: <span>The snake is a keystone species in the ecosystem.</span>

A hypothetical population of monkeys consists of two or more phenotypically different groups who extensively interbreed with one
Sedbober [7]

Answer:

The correct answer is option a, that is, sympatric speciation.

Explanation:

Speciation, which takes place when two groups of similar species live in a similar geographical location, however, they evolve distinctly unless and until they no longer interbreed and are regarded as different species is termed as sympatric speciation.  

Sympatric speciation is not similar to other kinds of speciation, in which the formation of a new species takes place when a population gets differentiated into two groups because of migration or geographic barrier. The sympatric speciation can be witnessed in various distinct kinds of species. Thus, the given case of monkeys is an illustration of sympatric speciation.

1. Describe the structure and function of each of the three types of RNA.
Ket [755]

Answer:

1.

mRNA - Messenger RNA: Encodes amino acid sequence of a polypeptide.

tRNA - Transfer RNA: Brings amino acids to ribosomes during translation.

rRNA - Ribosomal RNA: With ribosomal proteins, makes up the ribosomes, the organelles that translate the mRNA.

2.

Transcription is the process by which DNA is copied (transcribed) to mRNA, which carries the information needed for protein synthesis. Transcription takes place in two broad steps. First, pre-messenger RNA is formed, with the involvement of RNA polymerase enzymes.

3.

During translation, which is the second major step in gene expression, the mRNA is "read" according to the genetic code, which relates the DNA sequence to the amino acid sequence in proteins. Each group of three bases in mRNA constitutes a codon, and each codon specifies a particular amino acid (hence, it is a triplet code). The mRNA sequence is thus used as a template to assemble—in order—the chain of amino acids that form a protein.
