The probability of a child with a bent thumb is out of 4 is 50%.
Explanation:
Information given:
dominant gene = straight thumb (genotype TT, Tt)
recessive trait = bent thumb (genotype tt)
from the question genotype of parents can be deduced:
Parent 1 = Tt
parent 2 = tt
from the Punnet square:
T t
t Tt tt
t Tt tt
From the results of Punnet square it is seen that 50% of progeny will be straight thumb and 50% of progeny will be bent thump.
phenotype ratio and genotype ratio = 1:1
There will be 50 % probability that one of their offspring will be with bent thumb.
progeny with bend thump percent = 
x100
= 50%.
Answer:
A. Working memory
Explanation:
Working memory is a type of <u>short-term memory</u> that is associated with numerous basic processes and abilities, such as <u>decision making and problem solving</u>. It stores temporary information that will eventually be extremely useful for <u>day-to-day activities such as learning and comprehending both spoken and written information.</u>
However, short-term memory has a limit of information that we are able to store, also known as "limited capacity."
<em>For instance, when we are having an argument with someone, we tend to come up with responses or answers but we have to wait until the other person finishes talking. While they are talking, we are paying attention to the person but we are also remembering our own argument.</em>
The correct answer is letter c. land and water.
INRM or also known as Integrated Natural Resources Management is a systematic process or way to manage our natural resources, such as land and water. Land and Water are two major natural resources in our planet.
Answer:
The functional groups that define the two different ends of a single strand of nucleic acids are:
B. a free hydroxyl group on the 5' carbon a free hydroxyl group on the 3' carbon
G. a free phosphate group on the 5' carbon
Explanation:
A nucleic acid is a polymer formed of nucleotides that are linked with a phosphodiester bond. The structure of a nucleotide consists on a phosphate group linked to a pentose (ribose in RNA and deoxyribose in DNA) that is also attached to a nitrogenous base. The nitrogenous bases are adenine, guanine, cytosine, thymine (in DNA) and uracil (in RNA).
DNA and RNA are nucleic acids which can be found in a double or single strand presentation.
Nucleic acids are synthesize in the 5’ to 3’ direction, so that is why the convention is that the sequences are written and read in that direction.
The strand of a nucleic acid is directional with an end-to-end orientation, where the 5’ end has a free hydroxyl or phosphate group on the 5' carbon of the terminal pentose, and the 3’ end has a free hydroxyl group on the 3’ carbon on the terminal pentose (ribose/ deoxyribose).
