Left-handedness (r) is recessive in humans and right-handedness is dominant (R).
Tracy, a left-handed woman, and whose mother and brother are also left-left handed,
marries Sa who is right-handed. Sam's mother is left-handed and his father and sister
are right-handed. What is the expected genotypic ratio of the children Sam and Tracy
might have?
ORr:2rr:ORR
1Rr:2rr:1RR
2Rr:2rr:ORR
The expected genotypic ratio of their children is 2Rr:1rr:1RR.
What is Genotype?This can be defined as the genetic composition of an organism. Since Sam and Tracy possess heterozygous traits, their genotypes will be Rr and Rr.
When this is crossed , we will get :
Rr × Rr
RR Rr Rr rr
This means the genotypic ratio will be 2Rr:1rr:1RR.

distilled water has no impurities therefore it eliminates the sources of any contamination and gives accuracy to an experiment distilled water is also used to know if actually a chemical reaction takes place or not
how is atp produced in the photo phosphorylation
Answer:
Photophosphorylation is the conversion of ADP to ATP using the energy of sunlight by activation of PSII. This involves the splitting of the water molecule in oxygen and hydrogen protons (H+), a process known as photolysis.

Which of the following best describes the compositional layers of the earth? a. All layers of the Earth below the crust are liquid. b. The only liquid layer of the earth is the mantle. c. The crust floats on top of the outer core. d. Some layers of the earth are liquid, and some are solid. Please select the best answer from the choices provided A B C D
Answer:
The answer to this question is "D" Some layers of the earth are liquid, and some are solid.Explanation:
Core, mantle, and crust are divisions based on composition. The crust makes up less than 1 percent of Earth by mass, consisting of oceanic crust and continental crust is often more felsic rock. The lithosphere is composed of both the crust and the portion of the upper mantle that behaves as a brittle, rigid solid.
The option that correctly describes the compositional layers of the earth is : ( D ) Some layers of the earth are liquid, and some are solid.
Earth compositionThe earth is composed of the Core, mantle, and crust which are categorised based their varying composition. The crust consists of the oceanic crust and continental crust. WhileThe lithosphere is composed of both the crust and the portion of the upper mantle which are similar to brittle rigid solid.

a shallow, sheltered area near an estuary
a sunny, open area with lots of sand dunes
I NEED HELPPPP HURRRYYYY
Answer: a rocky, coastal area with very high tidesa shallow, sheltered area near an estuary
Explanation: because it’s an area low-lying land which is flooded in wet seasons or at high tide, and typically remains waterlogged at all times.
Answer:
C) a shallow, sheltered area near an estuary
Explanation:
A marsh is a shallow, sheltered area generally found near an estuary. They are often between aquatic and terrestrial ecosystems. Like other marine ecosystems, some marshes experience tides. Therefore, these tidal marshes are exposed during low tide and underwater at high tide. Marshes that are not as close to the coast are called nontidal marshes.

More information on marshes:
The producers that thrive in marshes are herbaceous, meaning they do not have woody stems. Just like estuaries, marshes are rich in nutrients and are home to an abundance of wildlife.

Composed primarily of pyramidal-shaped zymogenic cells that produce enzymes. What is the primary enzyme produced here, and what substance does it break down
The pyramidal-shaped zymogenic chief cells produce pepsinogens which act on proteins molecules.
What are chief cells?Chief cells are cells are located at the base of the gastric glands found also in the body and fundus of the stomach.
Chief cells are pyramidal-shaped zymogenic cells that produce enzymes such as pesinogen 1 and 11.
The pepsinogens are proenzymes or zymogens and are converted to the active enzymes person 1 and person 11.
Pepsin 1 and 11 are proteolytic enzymes and act on proteins to break them down.

Neurons have special proteins in their
cell membranes that allow them to generate
electrical current. Are these proteins most
likely produced by ribosomes on the rough ER
or ribosomes suspended in the cytoplasm?
Explain your answer.
Answer:
The ribosomes on the rough endoplasmic reticulum (RER) most likely produces neuronal special proteins.
Explanation:
Conduction of electrical impulses by action potentials of neurons takes place through controlled flow of charged ions through neuronal membranes. This ion transfer is controlled by specialized neuronal channel proteins which are present in the neuronal cell membrane.
These channel proteins allow for hydrophillic passage of ions and water molecules across the neuronal membranes.
Ribosomes that are attached to the RER are involved in protein synthesis. They carry the code for proteins carried by the mRNA and translate into respective protein.
The RER along with some free ribosomes cluster together as Nissl bodies and are mainly involved in neuronal specialized proteins.
