The correct answer is 2. suggests that a prokaryote ate another prokaryote to produce eukaryotes.

Lynn Margulis (1960) put forward the endosymbiotic theory. The theory states that aerobic bacteria, a prokaryotes require oxygen were engulfed by anaerobic bacteria, also prokaryotes which are poisoned by oxygen. They live together as symbiotic partners for mutual benefits. The aerobic bacteria take care of the toxic oxygen for the anaerobic bacteria, in return the anaerobic bacteria would ingested food and protected the aerobic bacteria. Thus, a eukaryotic cell with a double-membrane bound organelle is formed. The inner lipid bilayer is of engulfed bacterial cell plasma membrane, and the outer lipid bilayer is of bacterial cell that engulfed it.

Alex73 [517]

Answer:

Option-C

Explanation:

Traditional ecological knowledge is the knowledge acquired and adapted by the local or native people living in a particular area.

The traditional knowledge is gained by the holistic approach of gaining the knowledge that is which benefits survival and increases the chances of well being.

The approach aims at learning by making direct contact with the surrounding environment, learning its ways, understanding the relationship between the various factors and then adapting to the condition and utilizing the available information.

The traditional way aims at looking at the environment in whole but the modern way of understanding the environment aim by learning the environment in the components.

The traditional knowledge is always shared by the local people in their local language but since the ideology of gaining the knowledge differ in both the ways and TEK is shared in local language therefore sometimes the knowledge does not prove useful in the contemporary world.

Thus, Option-C is correct.

What is a gene? Can someone tell me what is Euchromatin? Is Euchromatin also called a Gene? What's the difference between these
julsineya [31]

Answer:

In biology, a gene is a basic unit of heredity and a sequence of nucleotides in DNA or RNA that encodes the synthesis of a gene product, either RNA or protein. During gene expression, the DNA is first copied into RNA.

Euchromatin is a lightly packed form of chromatin that is enriched in genes, and is often under active transcription. Euchromatin comprises the most active portion of the genome within the cell nucleus. 92% of the human genome is euchromatic.

The genes present in heterochromatin are usually inactive. The genes present in euchromatin are either already active or will be active during growth. Heterochromatin is transcriptionally-inactive. Euchromatin is transcriptionally. (This one here is the difference)

When human DNA molecules and chimpanzee DNA molecules are heated to separate the two sides of the molecules from each other and
Sloan [31]

Answer:

B. Humans and chimpanzees share a relatively recent common ancestor.

Explanation:

Both the humans and Chimpanzees are the primates that are they belong to the same group called hominids and genus called Homo.

When the DNA sequences of the Chimpanzees and the Humans are sequenced and compared than they showed that 98% of the genome is similar.

In the given question, the single strands of the humans and the chimpanzees base-paired which showed that 98% of the nucleotide sequence is the same. The most possible reason for this similarity is that they both were evolved from the common ancestors and they diverged recently in the past.

Thus, Option-B is correct.
