In your lab you are studying the genome of venomous rattlesnakes to find the gene which codes for their venom glands. One rattle

snake has a mutation and cannot produce venom. You compare his DNA to a normal rattlesnake. What type of mutation has occurred?
Normal: AATCGCTACGCACGTCAG
Mutated: AATCGCCATGCACGTCAG

The type of mutation that occurred here is an inversion of three nucleotide bases (Option A).

<h3>What is an inversion?</h3>

An inversion is a type of mutation where linear order of nucleotide in the mutated sequence is inverted.

In this case, we have an inversion that involves the following bases (bold highlighted) AATCGC TAC GCACGTCAG and AATCGC CAT GCACGTCAG.

In conclusion, this mutation is an inversion of the genomic sequence (Option A).

Rhizobium bacteria is found in ___ molecules of_____ plants​
Mashcka [7]

Answer:

Hope this helps :)

Rhizobia are a "group of soil bacteria that infect the roots of legumes to form root nodules". Rhizobia are found in the soil and after infection, produce nodules in the legume where they fix nitrogen gas (N2) from the atmosphere turning it into a more readily useful form of nitrogen.

Scientists studied reproduction in the New Zealand mud snail. They wanted to determine whether reproducing sexually or asexually
lubasha [3.4K]

A hypothesis is a claim that expresses a relationship between variables. D) Asexual reproduction is advantageous over sexual reproduction because it decreases the snails’ need for social interaction.

<h3>What is a hypothesis?</h3>

A hypothesis is a scientific conjecture, not verified, that requires corroboration. It is a possibility, but not a fact. It is a claim of how it works a relationship between two or more variables.

The researcher hypothesizes in order to predict what is going on or what is expected to occur.

A hypothesis must express what is expected to occur in a perfectly comprehensive manner. There must be a logical relationship between the involved variables. It must be objective. Usually, it is written in the present time.

There are different kinds of hypotheses: descriptive, correlative, differentiative, or causative.  

In the exposed example, researchers wanted to determine whether reproducing sexually or asexually was more beneficial for the snails.

Options,

A) <em>Sexual reproduction is advantageous over asexual reproduction because it reduces the rate of mutation accumulation. </em>

The benefit of reproducing sexually is that the risk of mutation is lower.

B) <em>Asexual reproduction is advantageous over sexual reproduction because it allows the snails to produce more offspring.</em>

<em />

The benefit of reproducing asexually is that a higher number of descendants are produced, which increases reproductive success.

C) Sexual reproduction is advantageous over asexual reproduction because it allows for snails to have increased genetic variation.

The benefit of reproducing sexually is that it increases genetic variation.

D) Asexual reproduction is advantageous over sexual reproduction because it decreases the snails’ need for social interaction.

The benefit of reproducing asexually is that there is no need for social interaction.

Social interaction does not really benefit snails as a species. This is not a variable that might influence in a significant way snails.

However, variables like the mutation rate, variability, and the number of descendants are useful to test how they benefit or not the snails.  

The hypotheses that would least likely aid the scientists to answer the question is <u>option D</u>.
