Explanation:
Phenylketonuria (PKU) is a disease that results from a recessive gene. Two normal parents produce a child with PKU. What is the probability that a sperm from the father will contain the PKU allele?
a. 2/3
b. 3/4
c. 1/3
d. 1/2
e. 1/4
Answer:
d. 1/2
Explanation:
According to this question, PKU (Phenylketonuria) is a recessive condition in humans. A normal human must possess at least a dominant allele in the gene.
In a situation where two normal parents produce a child with PKU. This means that both parents are heterozygous for the condition i.e Pp × Pp. Hence, the heterozygous male (Pp) will produce gametes in the following proportion: P (1/2) and p (1/2).
This means that the probability that a sperm from the father will contain the PKU allele (p) is 1/2 or 50%
living cells maintain a balance between materials entering and exiting the cell. their ability to maintain this balances called blank
PLEASE ANSWER ASAP!!!
Describe the difference between dominant alleles and recessive alleles.
THANK YOU SO MUCH!!
Answer:
When an allele is dominant, the characteristic it is connected to will be expressed in an individual. When an allele is recessive, the characteristic it is connected to is less likely to be expressed.

Explanation:
Importance of mitosis, two reasons and 300 words.
Answer: Mitosis is a way of making more cells that are genetically the same as the parent cell. It plays an important part in the development of embryos, and it is important for the growth and development of our bodies as well. Mitosis produces new cells, and replaces cells that are old, lost or damaged.
1. Development and growth
After meiosis has produced a gamete, and this has fused with another gamete to form an embryo, the embryo grows using mitosis. This growth continues throughout an organism’s life, in plants, animals, and fungi. In this way, the original chromosomal set is preserved.
2. Cell replacement
This occurs when the original cell is damaged or wounded. New cells are created to replace those that were damaged. Examples of this are the healing of a cut or a broken bone. When old cells die, new ones replace them to ensure continuing functionality.
3. Asexual reproduction
Single-celled organisms and certain multicellular organisms use mitosis for asexual reproduction. This includes reproduction by fragmentation, as in the case of planaria, and reproduction by budding, as in the case of sea anemones. Many plants reproduce using mitosis.
First, we need to understand what meiosis is. Meiosis is the replication of cells that results in each daughter nucleus containing half of the parent cell’s chromosomes. Meiosis is used primarily for the production of gametes, which are incorporated in sexual reproduction. Thus, the main difference between mitosis and meiosis is that mitosis produces somatic (body) cells, which can go on to become part of any bodily tissue, whereas meiosis only produces germ (sex) cells. Organisms which reproduce asexually cannot undergo meiosis, whereas all eukaryotic organisms undergo mitosis. Mitosis and meiosis are similar in that both can only occur in eukaryotic cells. This is because prokaryotic cells do not contain a nucleus within which to begin the processes of mitosis and meiosis. Instead, prokaryotes replicate themselves using binary fission. Both mitosis and meiosis begin with DNA replication in the parent cell to create four sets of chromosomes: in mitosis, these sets are split to form two diploid daughter cells, while in meiosis, these sets are split to form four haploid daughter cells. This is because cells undergo only one division in mitosis, whereas they undergo two divisions in meiosis.

What is the role of ATP in the process of active transport?
Answer: ATP plays a critical role in the transport of macromolecules such as proteins and lipids into and out of the cell. The hydrolysis of ATP provides the required energy for active transport mechanisms to carry such molecules across a concentration gradient. Active transport mechanisms do just this, expending energy (often in the form of ATP) to maintain the right concentrations of ions and molecules in living cells. ... Primary active transport directly uses a source of chemical energy (e.g., ATP) to move molecules across a membrane against their gradient.
Hope this helps... stay safe and have a great weekend!!! plz mark brainliest if i am right...
The role of ATP in the process of active transport is - It provides the energy that cells need to move molecules against a concentration gradient.
Active transport is the transport process where carrier proteins pick up specific molecules and take them through the cell membrane against the concentration gradient.
This transport requires cellular or metabolic energy which is available in the form of ATP molecules produced within the cell.ATP plays a critical role in the transport of macromolecules such as proteins, lipids, and ions into and out of the cell.The hydrolysis of ATP provides the required energy for active transport mechanisms to carry such molecules across a concentration gradient.Thus, the role of ATP in the process of active transport is - It provides the energy that cells need to move molecules against a concentration gradient.

4. Which is a factor that keeps Earth in orbit around
the Sun?
A. the gravitational pull of the Sun
B. the orbital path of the moon
C. the continuous motion of the universe
D. Earth's changing speed and direction
Answer: A. the gravitational pull of the Sun
The sun is providing a centripetal force pulling the earth inward toward the sun. At the same time, the inertia of the earth is making it want to move forward in a straight line. The two forces work together to create the net effect of the earth orbiting around the sun. Other planets, moons, asteroids, and celestial objects exert gravitational forces on the earth as well, but nowhere near the amount of what the sun does.
2. Which blood type would you have if antibodies A and B were made during your first year of life?
Answer: the possible possibilities are 3 if u have an A and B type of antibodies.
Explanation:
it can be -- AO or AB or BO
plus factor will depend upon enzyme presence.
If a person is having both anti-A and anti-B antibodies in blood then the possible blood group of that individual can be O. However, Rh factor cannot be determined by this information.
What is Blood Group?Blood grouping is the system of classification of blood on the basis of antibodies and antigens in blood which are inherited substances present on the surface of the red blood cells.
Blood groups are classified into four types. These are A, B, AB and O. Blood group A has antigens A on the RBCs with anti-B antibodies present in the plasma. Blood group B has B antigens on RBCs with anti-A antibodies in the plasma. Blood group O has no antigens on the membrane of RBCs and antibodies of both types anti-A and anti-B antibodies in the plasma. Blood group AB has both A and B antigens, but no antibodies in the plasma.

How can you tell the difference between alternate and opposite leaf arrangements?
They are based on based whether the leaf pinnate or palmate venation.
They are based on based whether the leaf has one or two leaves at the node.
They are based on based whether the leaf has a smooth or toothed margin.
They are based on whether the leaf is simple or compound.
Answer:
They are based on based whether the leaf has one or two leaves at the node.
Explanation:
Answer: They are based on based whether the leaf has one or two leaves at the node.
Explanation: You can tell the difference between alternate and opposite leaf arrangements based on whether the leaf has one or two leaves at the node. Alternate leaf arrangement is when a single leaf is attached at one location on the stem, the node, in an alternating pattern. On the other hand, the opposite leaf arrangement is when two leaves are attached to the same node on opposite sides of the stem.
