Which of the following sentences correctly uses a pronoun to create emphasis?
O He, Jacob Smith, studied for 10 hours.
O He himself wrote the 20-page paper.
O He and they trained for the marathon.
O Himself worked for weeks on the project.
The correct answer is B. He himself wrote the 20-page paper.
Explanation:
Pronouns such as himself, yourself, themselves, or myself, which are known as intensive pronouns, are used to emphasize the subject of a sentence, usually by placing the pronoun right the subject or main pronoun. This can be seen in the sentence "He himself wrote the 20-page paper" because the pronoun "himself" emphasizes the action "wrote" performed by "he", which is the main subject of the sentence. According to this, it is in the second sentence a pronoun creates emphasis.
The diagram shows the position of earth during solstice. select the area that would be getting around 24 hours of daylight each day.
The answer is Artic Circle Zone (red square at the top)
Explanation:
A solstice occurs two times in a year when the Sun reaches farther either the south or the north of Earth. In the image presented, there is a solstice because the sunlight reachers farther in the North. Additionally, this phenomenon occurs due to the tilt (inclination) of Earth, and it increases the number of daylight/night hours in different zones.
In the case of the Arctic Circle Zone (north pole) it is likely during the solstice, this zone has around 24 of daylight each day because almost all this zone is directly exposed to the sunlight, and therefore this will always be reached by sunrays despite the rotation of Earth (rotation of Earth in its axis). On the other hand, other zones will not be exposed to sunlight all the time because the location and rotation will cause these areas are in the dark zone of Earth during specific hours every day.
Answer: The top red square near the axis.
Explanation:
Ok, the Earth's axis is the "line" around which the Earth rotates.
This means that after a rotation, the 3 bottom red boxes will be in the dark side of the diagram ( for example, if you have a ball and you grab it with the logo facing you, when you rotate the ball, the logo will be in the other side, and you will not be able to see the logo).
Now, as the area near the axis actually does not move that much, the red square near the axis (the top red square) will be most likely getting 24 hours of light each day.
Summarize the differences between how the salt-sensitive plant cell and the salt-resistant plant cell behave in the 10% salt solution..
Answer:
Salt sensitive plants when exposed to a 10% salt solution will result in the water in the plant cell to leave and get attached to the salt solution through the process called Osmosis. Osmosis is a phenomenon which occurs as a result of movement of fluid from a region of lower concentration to a higher concentration.
This causes the plant cells to shrink and wilt.
However when a salt-resistant plant is exposed to a 10% salt solution osmosis doesn’t occur and the plants remains the same without any form of shrinkage or wilting.
A plant that is sensitive to salt means that when it is placed in a salt solution it's cell structure will change by the process of osmosis.
Osmosis is the movement of water molecules through a semi permeable membrane from a region of low solute concentration to a region of higher solute concentration.
Therefore when the salt sensitive plant is placed on the 10% salt solution, there would be water loss from the intercellular compartment to the extracellular leading to the protoplasmic shrinking called plasmolysis.
A plant that is resistant to salt means that the plant is not in anyway affected when placed in a salt solution.

write two functions of Endoplasmic and reticulum
Answer:
there are two types of endoplasmic reticulum, rough endoplasmic reticulum and smooth endoplasmic reticulum, the rough endoplasmic reticulum is the site of protein manufacture( because it has ribosomes) whereas the smooth endoplasmic reticulum manufactures fat molecules or lipids. these lipids helps in membrane biogenesis, which is the process of formation of plasma membrane. the main function of the endoplasmic reticulum is that it serves as channel for transportation of proteins etc between various cells or a cell organelle and another cell. In the liver, detoxification of poisons take place due to the help of smooth endoplasmic reticulum.

A tumor cell with a mutation in Rb can divide in the absence of extracellular signals. A. If the Rb mutation is responsible for the increased cell division, is it likely that Rb is always active or always inactive
Answer:
The Rb will always stay active
Explanation:
The Rb, undergoing a mutation that promotes cell proliferation, the cells will proliferate excessively, either benignly or malignant, forming a tumor structure.
The Rb mutation is considered an irreversible process, which will generate an unlimited and excessive growth that is abnormal when compared to the other non-mutated cells.

Chorionic villi are more prolific Select one: a. Adjacent to the yolk sac b. Opposite the cervical os c. Near the implantation site d. Adjacent to the uterine fund us
Answer:
Adjacent to the yolk sac
Explanation:
Chorionic villi are microscopic and fingerlike projections found near the placenta which contain capillaries, increase surface area of blood that allow blood to flow and transfer nutrients from the mother to the fetus. The chorionic villi is adjacent to the yolk sac because it developed from the yolk sac, villi can extend and contact maternal blood vessels thereby nourishing the embryo and transfering nutrients from the mother to the fetus.

Friedrich Meischer, a Swiss physician and biologist, is credited with the discovery of nucleic acids. The correct option is A.
What is Nucleic acid?
Nucleic acids are complex macromolecules that play a fundamental role in storing, transmitting, and expressing genetic information in living organisms. They are essential for the inheritance of traits and the functioning of cells. There are two main types of nucleic acids: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).In the late 1860s, Meischer was conducting experiments on white blood cells (leukocytes) and noticed that these cells contained a substance that was different from proteins.
He isolated this substance, which he called "nuclein," from the nuclei of white blood cells.
Meischer's discovery laid the foundation for our understanding of nucleic acids.
Thus, the correct option is A.

Answer:
This population of fish is undergoing the process of Genetic diversity
Explanation:
The phenomenon known as Genetic diversity is described as variation that occurs within a species or community. Individual organisms are unique owing to their genetic makeup. Ample variation within a population, or genetically diverse population, allows it to better survive various sorts of stresses from the environment, ensuring better survival of the species.
The famous radiation of Galapagos finches from the common ancestor species on the Western coast of South America is probably a result of
Answer:
Adaptive evolution
Explanation:
The radiation of finches in the Galápagos archipelago is the result of the natural selection process described by Darwin as adaptive evolution. Evolution is the process for which the organisms better adapted to its environment have more chances to survive and to reproduce, thereby leaving more offspring in the next generation.
Moreover, adaptive evolution refers to the mechanism for which species evolve by the emergence of advantageous mutations that are fixed through positive selection, thereby favoring the phenotypes that have higher adaptive fitness.
The enzymes cannot metabolize the fat and the fat soluble vitamins are not absorbed to any great degree. You are now waiting on the taste test results. You are, however, a little fearful that this "fat" will not become the diet option you are hoping for because:___________
Answer:
fat is not being obsorved in body on any great degree
because the inability to metabolize fats and the poor absorption of fat-soluble vitamins indicate potential issues with the digestion and absorption of dietary fats. If the taste test results reveal that the "fat" in question is not palatable or does not meet the desired flavor profile, it could be a significant obstacle in promoting it as a favorable diet option.
This indicates that the body is encountering challenges in breaking down and utilizing dietary fats. Fat metabolism is a complex process involving enzymes that break down fats into smaller components, such as fatty acids and glycerol, which can be utilized for energy production or stored in adipose tissue. If the enzymes responsible for fat metabolism are not functioning properly, it can lead to difficulties in properly utilizing fats from the diet.

ASAP You are observing proteins in a lab for an experiment. During transport, they have started to unwind and lose their shape. You notice long strands wound into alpha helices. What level of structure are the proteins in? A. Quaternary B. Primary C. Secondary D. Tertiary
Answer:
C. Secondary
Explanation:
In proteins, the structure of local segments can be arranged into three different three-dimensional formations: alpha helices (α-helix), beta sheets (β-strand) and omega loops. An alpha helix is the most common secondary protein conformation because it has low-energy and a stable arrangement. The α-helix is formed by the interaction between amino acids of every backbone N−H hydrogen bonded with the backbone C=O group of the corresponding amino acid residue in the polypeptide chain. The α-helix motif is very common in transmembrane segments of proteins that cross the lipid bilayer.
