Is knowing the abo blood type of a potential blood donor enough to determine a suitable match? explain your answer?
Firlakuza [10]
Compatibility in the ABO blood type is necessary for the blood transfusion, but that is not sufficient to determine the possible donor.
The Rh factor should also be taken into consideration when determining blood transfusion compatibility. A person can be Rh positive or negative, and the Rh positive Rh blood donors can only donate to other Rh-positive people.

A que altura debe moverse un costal de cemento de 50kg para asegurar que su energía potencial sea de 10,500 j?
Juli2301 [7.4K]

Answer:

21 m

Explanation:

La energía potencial de un cuerpo es la energía que posee el cuerpo en virtud de su posición.

La energía potencial se da como;

E = mgh

Dónde;

m = masa del cuerpo

g = aceleración por gravedad

h = altura del cuerpo

Aquí necesitamos obtener la altura del cuerpo.

h = E / mg

h = 10500/50 * 10

h = 21 m

Plants make their own food and are called producers. What do plants need to make their own food? A) soil, air and water B) soil,
djyliett [7]

Answer:

D) energy from the sun, air, and water

Explanation:

Plants are producers because they undergo photosynthesis. Photosynthesis is the process of taking sunlight, CO2, and water to produce ATP in the form of glucose and oxygen.

For plants to make their own food they require the reactants of photosynthesis. The reactants are sunlight+6CO_2 + 6H_2O. In other words, sunlight, carbon dioxide (air), and water. Without these reactants, photosynthesis cannot occur.

Things such as soil and fertilizer are helpful to a plant's growth; however, they are not required in the process that creates food for plants.

How would a change to the sequence of nucleotides in a DNA segment affect the mRNA transcribed from the DNA?​
Mama L [17]

Answer:

It would change the nucleotide sequence of the transcribed mRNA

Explanation:

During the process of transcription, a DNA template is used to synthesize a mRNA molecule. The nucleotides in the DNA molecule undergo a complementary base pairing to form the nucleotides on the mRNA. This means that the order of sequence on the DNA determines the order of sequence on the mRNA.

In a case where the nucleotide sequence of a DNA segment changes in the process of MUTATION, the sequence of nucleotides in the mRNA strand will also change. For example, if sequence: ATT on the DNA produces UAA on the mRNA, a change to AAT on the DNA will cause the mRNA sequence to change to UUA.
