Answer:

The limitation of phylogenetic species concept is b. Evolutionary histories are not known for all species.

Explanation:

The species that share a common ancestor and have similar traits and functions are grouped together as a result of the phylogenetic species concept. The phylogenetic species concept shows a unique evolutionary history of one organism with another of the same group. The major set back in the phylogenetic species concept is the lack of evolutionary histories for certain species. So, these organisms cannot be grouped according to the phylogenetic species concept.

Darya [45]

Answer:

Option A , Genome

Explanation:

Microarrays that contains array of single stranded DNA are used to study thousands of gene expression for all the genes of a genome and are usually termed as DNA miscroarrays. These microarrays being single stranded allows attachment of complementary DNA strand to bind to their surface. The mRNA from the cell is extracted and converted into cDNA which is further used for DNA cloning.

Hence, option A is correct

Question 5

ArbitrLikvidat [17]

The environmental effects of an individual or group in terms of resources used and waste produced is an individual or group's ecological footprint (option A).

<h3>What is ecological footprint?</h3>

Ecological footprint is the measure of how much biologically productive land and water area an individual, population or activity requires to produce all the resources it consumes and to absorb the waste it generates using prevailing technology and resource management practices.

Living organisms make use of resources in the environment and these can either leave negative or positive effect on the environment that will affect sustainability.

Therefore, it can be said that the environmental effects of an individual or group in terms of resources used and waste produced is an individual or group's ecological footprint.

After researching the rock they found, Mary and Jim believe it contains large pieces of the mineral limonite. They observed that

WINSTONCH [101]

The hypothesis can be defined as an educated guess, which is made by the scientists doing a scientific research.

In this case, the scientist want to test the presence of the limonite in the yellow rocks, So, proposed hypothesis should include the color of rock they want to observe and the posssible outcome, which need to be tested.

So, a proposed hypothesis can be:

<h3>The rocks, which have yellow color are made up of mineral limonite. </h3>

LekaFEV [45]

I believe the appropriate answer is, short amino acid chains, NAG, NAM, and some lipid proteins.
Peptidoglycan is also known as Murein, it is a polymer consisting of sugars and amino acids that form a mesh-like layer outside the plasma membrane of most bacteria, forming the cell wall. The sugar component consist of alternating residues of β-(1,4) linked N-acetylglucosamine (NAG) and N-acetylmuramic acid (NAM),
