Species A: GTTGAGCTAGTATGGACC
Species B: GATAAGCTAGTAAGGTCA
These species differ in 5 nucleotides.
This number should be multiplied by the rate of mutations; that is;
5 × 15 million years =75 million years.

Correct answer: B). Phylogentic system of classification
The scientist will use the phylogenetic system of classification. As is uses evolutionary relationship for classifying an organism. The phylogenetic relationship between the organism is given by the degree of evolutionary distance. This system names only clades which are a group of organism that is descended from the common ancestor.
Hence, the correct answer would be option B

The correct answer will be option-B.
In the given study, the people were selected with different ranges of vision loss to study the effectiveness of seeing by looking at the dogs of an eye.
These persons showed variance in their ability to see as the vision depends on the age along with occupation they were in or they are in. The strongest factor that influences the ability to see was the occupation which leads to different ranges of vision.
Thus, Option-B is the correct answer.

QUESTION POSTED AT 18/02/2020 - 03:29 AM
Both the parents must be the carrier of recessive genes along with dominant gene
Recessive genes are genes that are expressed only when two recessive alleles are inherited from the parents.
A dominant gene is expressed in two cases a) when two dominant alleles are inherited or b) when one dominant and one recessive allele are inherited.
since parents have normal fur color but they are producing white fur coloured deer (Albinitic offsprings) this means that both of the parents must be the carrier of recessive genes.
Let the allele for “normal fur colour” be expressed by C
Allele for “white fur color” be expressed by c.
Both the parents have heterozygous dominant gene (which is carrier if recessive allele "c"), thus their genotype would be Cc
Let see the punnet square below -
C CC Cc
c Cc cc
Out of the four offspring’s produced only “cc” represents white fur deer.

QUESTION POSTED AT 18/02/2020 - 01:07 AM
The right answer is It has peptidoglycan.
Eubacteria are not multicellular beings, but are unicellular.
Eubacteria certainly have a cell wall, but we must not forget that plant cells also have a cell wall, so this is not really a feature.
Eubacteria are microorganisms but there are eukaryotic microorganisms, so it is not a characteristic.
Peptidoglycan (or murine, or mucocomplex, or mucopeptide) is a characteristic component of the bacterial wall (not found elsewhere) maintaining the shape of cells and providing mechanical protection against osmotic pressure. It forms a thin layer in Gram-negative bacteria and a thick layer in Gram-positive bacteria.

Its a logical process in which a number of premises all believed true or sometimes found true most of the time and combined to come up with specific conclusions. Its mostly used in applications that do involve behavior, forecasting and makes broader generalization that is considered probable. For example a speculation that all crows are black and each time a new crow is observed and found out that its black the assumption is increasingly confirmed. On the other hand if the crow is found not to be black then the assumption's found to be false..

A renewable service is more valuable than a non-renewable service because it reduces the impact in the environment and it won´t run out.
A renewable service produces little to no global warming emissions which helps the environment. Also, a renewable service can be replaced and used repetedly so it won't run out.

Answer: The given statement is true.
When we go near a dog who is starving then it is likely that he might bite our hand because he will feel that we are actually trying to take his food away from him.
Since, food is the need of every living being so, this basic need makes the dog act defensively for his food.
Therefore, the statement a starving dog might bite your hand if you were near his food. This behavior is based on needs is true.
