Answer:
Selectively permeable or semipermeable means specific substances are allowed to pass through the plasma membrane.
Explanation:
The plasma membrane is selectively or semipermeable in nature because the plasma membrane allow only specific molecules such as nonpolar substances or hydrophobic substances such as steroidshormone to pass through it and prevent the passage of polar solute molecules such as water,glucose.
To transport these polar solutes across the membrane an additional protein is needed in case of transport of water channel protein is needed whereas in case of glucose transport carrier protein is required.
I<span>t is important for Mendel to study such a large sample of pea plants to determine the probability of inheritance because</span> higher sample size gives more accurate results.
>>>Mendel coined the terms “recessive” and “dominant<span>” in reference to certain traits.One best association to this is is his study about pea plants. According to him, green peas are recessive and yellow peas are dominant.</span>
Answer:
In biology, a cladogram can be described as a diagram which shows evolutionary relationships among different organisms. A cladogram shows which organisms share evolutionary history and which organisms are more closely related to one another.
<em>The cladogram in the above picture shows that the limbs originated after the jaws. </em>
The cladogram shows that amoeba was a common ancestor to sponges, earthworms, salmon, lizards, kangroo and cats.
I believe this is an example of frameshift mutation.
Frame shift mutation is a type of mutation that is caused by addition or deletion of a base pair or base pairs in the DNA of a gene resulting in the translation of the genetic code in an unnatural reading frame from the position the position of the mutation to the end of the gene.
Based on the principle of phylogenic tree building principle. the right answer is:
C) <span>The genomes of three species of mouse are being sequenced, and a particular DNA sequence found in all three species is found to have a steady mutation rate. The sequence of interest for these three species is shown below.
A and C has only 5 differences.
A and B has 7 differences.
B and C has 9 differences.
