scientists have used mtDNA as a molecular clock to trace human evolution and early migration routes explain why mtDNA would be more useful in this research than rRNA

Answers

An unknown mtDNA sample sample is matched to a sample of mtDNA that was found at the crime scene. This is how mitochondrial DNA (mtDNA) typing is used in forensic science.

Unlike nuclear DNA typing, mtDNA isolation is quite easy because its number is quite large. mtDNA copies rang from 100 to 10,000 per cell. It is also more stable and stronger than the nuclear DNA; that is why even unsolved cases from years ago use mtDNA typing as reference for possible conclusion.

Organisms that have a physical trait that makes it easier for them to access food supplies are unlikely to pass on that trait to their offspring.true or false

Answers

The right answer is false.

All the physical characteristics of an individual, which are at the basis of genetic characters (sometimes even epigenetic), are transmitted to his offspring.

Classical or monogenic Mendelian inheritance is based on the transmission of a single gene in a dominant, recessive mode, linked to the sex chromosome X (or Y), or more rarely mitochondrial (extranuclear) chromosome.

False, the physical trait that makes it easier for an organism to access food supplies is likely to pass from the parents to the offspring.

Further Explanation:

Traits refer to the characters that are present or expressed by the organism. Some of the traits are inherited while others are acquired during the lifetime of an individual.

Inheritance is the term which is used to refer to the condition when certain traits are passed on from the parents to offspring.

Offspring are more similar to their parents than to others as the genes that encode a protein and ultimately lead to the expression of traits that are passed on from parents to offspring.

The physical trait that confers an organism’s ability to access food supply is likely to pass from parents to their next generation. Example: Giraffe having a long neck can easily eat leaves from tall trees so they pass on this trait to their offspring also.

How many planes of symettry can you draw through a jelly fish?A-None
B-2-5
C-1
D-More than 5

Answers

I believe that the answer is B.) 2 - 5.


My reason being is because symmetry basically means 3-D , So you are asking how many sides can you see when looking through a jelly fish.

When looking through any jelly fish you will see 2-5 sides , 2-5 because there are four ( 4 ) , There is the front , the back and also both sides so it's four ( 4 ). 

That was my reason for the answer I chose.

 It would be D but you will not see at lease 5 sides to a jelly fish , why? = because they don't have 5 sides , most of them are square shaped or circular.

Summer rains and bad weather in Europe in the early fourteenth century resulted in _____.

Answers

Famine

In the early 14th century, Europe encountered a series of famines, often referred to as the Great Famine. Abundant rains in the spring of 1315 were partly responsible, along with cool warmth. This did not enable the cereals to ripen, which led to crop failures. It also recommended that straw and hay could not be preserved for animals and that salt was not available because the ocean could not evaporate. Moreover, the population had expanded very suddenly prior to 1300, so there was an additional requirement on limited sources.
The answer should be Crop Failure.
