Answer:
B
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%

When a cell makes a protein which path does the new protein follow
Answer:
rough ER → ER-to-Golgi transport vesicles → Golgi cisternae → secretory or transport vesicles → cell surface (exocytosis)
Explanation:
rough ER → ER-to-Golgi transport vesicles → Golgi cisternae → secretory or transport vesicles → cell surface (exocytosis)
The proteins move from the rough ER to the transport vesicle and cisternae of the Golgi apparatus and, further with secretory or transport vesicle, are released from the cell surface (exocytosis). Thus, option A is correct.
What is the secretory pathway?The protein pathway (secretory) is the mechanism of the transportation of the newly synthesized proteins by ribosomes that are transported out of the cell. The proteins are first present on the ribosomes of the ER.
For post-translational modification proteins from rough ER are transported to the Golgi apparatus. From the Golgi vesicles and cisternae, the proteins are packed in the secretory or transport vesicles to the cell surface where they are thrown out of the cell by exocytosis.
Therefore, the pathway of the newly synthesized protein is rough ER → ER-to-Golgi transport vesicles → Golgi cisternae → secretory or transport vesicles → cell surface (exocytosis).

For the trait of hair color, only one of the alleles from each parent gets passed down to the offspring because of the
principle of Independent assortment
principle of segregation
principle of genetics
principle of the next generation
Answer:
Explanation:
principal of genetics
For the trait of hair color, only one of the alleles from each parent gets passed down to the offspring because of the principle of segregation that is in the second option as segregation explains how the alleles are separated.
What is the significance of Mendel's law of segregation?Mendel's law of segregation is very significant as it explains that during the formation of gametes, each parent will pass down only one allele for a given trait to their offspring, and each gamete receives unique genetic information from its parents. Through the law of segregation, the offspring that are produced are different from each other.
Hence, for the trait of hair color, only one of the alleles from each parent gets passed down to the offspring because of the principle of segregation that is in the second option as segregation explains how the alleles are separated.

How is Earth dependent on the sun for energy?
Answer:
Nothing is more important to us on Earth than the Sun. Without the Sun's heat and light, the Earth would be a lifeless ball of ice-coated rock. The Sun warms our seas, stirs our atmosphere, generates our weather patterns, and gives energy to the growing green plants that provide the food and oxygen for life on Earth.
Explanation:
Without the energy of the Sun, there is no life possible on the Earth's surface. This is because the Sun is the only source of energy for plants and animals.
What do you mean by Energy?Energy may be defined as the power to do work to perform several metabolic activities by the organisms.
The energy of the Sun is captured by green plants in order to perform photosynthesis and make food. Through this process only, the oxygen will be available on the Earth's surface which is inhaled by other living organisms for the purpose of survival.
Without Sun, the earth looks like a ball of ice with coated rock and life less.
Therefore, it is well described.

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.

A. supplemented media permit growth of auxotrophic strains of Nourospora
B. X-irradiation can induce mutations.
C. two strains of auxotrophic Nourospora that grow on minimal medium supplemented with biotin have mutations in the same gene
D. auxotrophs fail to grow on minimal media In their first round of screening. Boodle and Tatum plated spores on minimal medium
Answer: C. two strains of auxotrophic Nourospora that grow on minimal medium supplemented with biotin have mutations in the same gene
Explanation: The Beadle and Tatum experiments had the exception that two strains of auxotrophic Nourospora that grow on minimal medium supplemented with biotin have mutations in the same gene. Thus they played a role in confirming the one gene, one enzyme hypothesis which is the idea that each gene encodes a single enzyme.
While correct but not exact, the hypothesis was confirmed through the use of genetic and biochemical studies of the bread mould Neurospora which were unable to make specific amino acids when mutated as a consequence of a "broken" enzyme needed to build a certain amino acid.

What is salinity?The concentration levels of salts in water or soils are referred to as "salinity."
Salinity is classified into three types based on its cause: primary salinity (also known as innate salinity), secondary salinity (also known as dryland salinity), and supplementary salinity (also called irrigation salinity).
When the water table rises, natural salts rise to the surface; in sufficient quantities, these salts become toxic to most plants.
As a result, the surrounding seawater becomes saltier because salt is left behind when sea ice forms.
As seawater becomes saltier, its density rises and it begins to sink. Surface water is drawn in to replace sinking water, which eventually cools and salts enough to sink.
Thus, the correct option is C.
