Blood type is controlled by the inheritance of any two of the following alleles: IA, IB, or i. IA codes for type A blood. IB codes for Type B blood. Both IA and IB are codominant. The i allele is recessive and will cause Type O blood whenever two copies of the allele are present.
If a mother has Type AB blood (IAIB) and a father has Type O blood (ii), what percentage of their children are likely to have Type A blood?
A. 25%
B. 50%

ASAP IMAGE IS ATTACHED THIS IS NOT DIFFICULT
There are only 4 types of nucleotides in mRNA and 20 types of amino acids in proteins. This figure shows how 4 types of nucleotides can provide a unique code for each of the 20 types of amino acids.
6a. The mRNA code for each type of amino acid is a
sequence of _______ nucleotides, called a codon.
(2 / 3 / 4)
6b. In the figure, which mRNA codon codes for the amino acid Phe?
Answers
Answer:
The mRNA code for each type of amino acid is a sequence of three nucleotides, called a codon.mRNA codon that codes for the amino acid Phe es UUU.Explanation:
The messenger RNA (mRNA) has in its structure sequences of 4 nucleotides adenine, uracil, guanine and cytosine. The possible combinations of these nucleotides to group into triplets is 64 codons to form 20 amino acids, from which it can be concluded:
An amino acid can be encoded by more than one codon. From these combinations the three STOP codons are obtained.A mRNA codon is a sequence of three nucleotides that serves to encode an amino acid.
Phenylalanine (Phe), according to the image, is formed with the UUU codon.

What is one way people have negatively affected land resources?
A) Habitat restoration
B) Urbanization
C) Terrace farming
D) Reforestation
Answers
Answer:
b
Explanation:
Urbanization is one way people have negatively affected land resources. Therefore, the correct option is B.
What is Urbanization?The process of urbanization occurs when the percentage of a country's population living in urban areas increases. This is a result of rural-urban migration, which occurs when people move from rural to urban areas in search of better job prospects, social services, and living standards. Urbanization has both beneficial and harmful effects on the environment and society.
On the plus side, urbanization can promote economic growth, better infrastructure, and greater access to social services, including healthcare, education, and social assistance. Additionally, it helps reduce stress on rural communities, which may experience issues of resource scarcity, resource overabundance, and environmental degradation.
Therefore, the correct option is B.

Which level of organization is represented by the skeleton of the snake?
А.organ
B.organism
C.tissue system
D.organ system
Answers
Tissue system, enables the snake to move forward by pushing against the ground while bending and curling its body. Thus, option C is correct.
What level of organization are present in snake?The body of a snake is long and slender, and it is separated into four quadrants. Head, esophagus, heart, and trachea make up the first quadrant's major structures.
The second quadrant contains the liver, stomach, and anterior, vascularized region of the lung(s).
A snake has a basic skeleton because it has no arms or legs. Hundreds of ribs extend from the base of the tail to the end of the long, flexible spine that connects the head to the backbone.
This enables the snake to move forward by pushing against the ground while bending and curling its body.
Therefore, tissue system level of organization is represented by the skeleton of the snake.

Smooth ice reduces the inertia of the hockey puck.
Smooth ice increases the force used to accelerate the hockey puck.

Smooth ice decreases the reaction force that the ice exerts on the hockey puck.
Answers
It is important to keep the ice smooth on a hockey rink because this reduces the unbalanced forces that would slow the hockey puck.
Frictional forcesFrictional forces are opposing forces to the motion of an object on a platform.
In order to be able to pass a puck as quickly as possible on a hockey rink, there should be a minimal frictional force on the ice surface on which the puck moves.
With minimal opposing forces, the puck will move as unhindered as possible and passing as fast as possible would be easy.
