A cell that is 3% salt is placed in a container of pure water.

Answer:

If there is 5% salt on the outside of the cell and 20% salt on the inside of the cell, the environment would be considered osmotically imbalanced or osmotically stressed.

Explanation:

In general, cells are surrounded by a membrane that separates the inside of the cell from the external environment. This membrane is selectively permeable, meaning that it allows certain substances to pass through while blocking others. In the case of a cell in an osmotically imbalanced environment, the concentration of solutes (such as salt) is different inside and outside the cell, which can cause water to flow in or out of the cell in an attempt to balance the concentration of solutes on both sides of the membrane.

If the concentration of solutes is higher inside the cell than outside (as in the case you described, with 20% salt inside and 5% salt outside), this can lead to an excess of water inside the cell, which can cause the cell to swell and potentially rupture. On the other hand, if the concentration of solutes is higher outside the cell than inside, this can cause water to flow out of the cell, leading to dehydration and potentially damaging the cell.

Osmotic stress can have a range of effects on cells, depending on the severity and duration of the imbalance. In some cases, cells can adapt and survive in an osmotically imbalanced environment, but in others, the stress can be lethal.

A DNA molecule with 1000 base pairs would further in the gel more than one with 200 base pairs.

The speed at which the molecules move through the pores in the gel is inversely proportional to their lengths. This indicates that a smaller DNA molecule will move through the gel further than a larger DNA molecule.

Gel electrophoresis is a method that researchers use to measure the size of DNA fragments. In this procedure, tiny holes called wells are positioned at the edge of a gel along with unknown samples and a DNA standard. The standard includes base pair-measuring fragments of known sizes.

DNA has 200 bases, so 2003420=340A.

A DNA segment that is 1700 base pairs long therefore contains 500 base pairs or 1000 nucleotides.

C. sunlight, carbon dioxide, water

Explanation:

The structure being referred to in this question is CHLOROPLAST, which is an organelle in plant cells saddled with the responsibility of making food (sugar) via the process of photosynthesis. In order for the photosynthetic process to occur, three major components or raw materials are needed.

The three items that is relied upon by chloroplast in order to perform its photosynthetic function are sunlight, carbon dioxide (CO2), and water (H2O). The CO2 enters the plant from the atmosphere/air while the H2O is absorbed by the roots of plants. The light is absorbed by certain pigments in the chloroplast called CHLOROPHYLL.

true. Protein complementarity is the practice of combining sources of protein such that amino acid deficiencies in one source are counterbalanced by abundances in another source.

A dietary strategy for protein nutrition called protein combining or protein complementing claims to maximise the biological benefit of protein consumption. According to the notion, vegetarian and vegan diets might not contain enough of some important amino acids, necessitating the combination of protein with different foods to create a complete protein intake. Regarding plant protein, the concepts of full and incomplete are no longer applicable.

I know that Diuron caused the coral to bleach​​​ because the coral expelled the algae that are living in their tissues.

This is referred to as a herbicide which is made up of substituted urea and it is used for the control of  crop and noncrop areas. Its mechanism of function is that it is able to inhibit photosynthesis which prevents plant growth.

In a situation where corals bleach, they turn white which is as a result of them expelling algae in their tissues due to different types of stressful conditions. An exposure to chemicals or a high pH may result in this condition also.

In this scenario we were told that the coral bleached however diuron inhibits photosynthesis which could have caused the expulsion of the algae which is why it was chosen.

Answers: I think it’s a or c

Explanation:

The following statement “Antigenic variation is common in influenza B and C but is rare in influenza A.” is False.

Antigenic variation is actually more common in influenza A compared to influenza B and C. Influenza A viruses are known to undergo frequent antigenic changes through two mechanisms: antigenic drift and antigenic shift.

Antigenic drift refers to the gradual accumulation of genetic mutations in the surface proteins of the influenza virus, namely hemagglutinin (HA) and neuraminidase (NA). These mutations can result in minor changes in the viral antigens, allowing the virus to evade recognition by previously acquired immune responses. Antigenic drift is responsible for the seasonal flu epidemics and the need for annual influenza vaccine updates.

Antigenic shift, on the other hand, is a more dramatic and rare event where there is a reassortment of genetic material between different influenza A strains, typically of animal origin. This can result in the emergence of a novel subtype of influenza A virus with a completely different HA or NA protein. Antigenic shift events have the potential to cause pandemics because the human population has little to no pre-existing immunity against the new subtype.

While antigenic variation can occur in all three types of influenza viruses (A, B, and C), it is indeed more common in influenza A due to its ability to undergo both antigenic drift and antigenic shift.

Fast-twitch muscle fibers are the fastest to contract and produce the most power. Option B is correct.

Fast-twitch muscle fibers, also known as type II fibers, are one of two types of skeletal muscle fibers, the other being slow-twitch (type I) fibers. Fast-twitch fibers contract quickly and forcefully, making them capable of producing high levels of power and speed, but they also fatigue quickly.

Fast-twitch fibers are further divided into two subtypes, type IIa and type IIb, with type IIb fibers being the fastest and most powerful. Type IIb fibers are primarily used for short bursts of high-intensity activity, such as sprinting or powerlifting.

In contrast, slow-twitch fibers contract more slowly and are better suited for endurance activities, such as distance running or cycling. They are more resistant to fatigue and have a higher capacity for oxidative metabolism, which allows them to produce energy from aerobic respiration. Option B is correct.

The hominin line is the term used in the lab manual to refer to humans and our ancestors/relatives after our split from the African apes.

Hominins are a group of primates that includes modern humans (Homo sapiens), as well as extinct human species and their close relatives, the hominin line diverged from the African apes, such as chimpanzees and gorillas, around 6-8 million years ago. This divergence led to the development of unique characteristics in the hominin line, such as bipedalism, increased brain size, and the use of tools. Over time, various hominin species emerged, adapted to their environments, and evolved. Some notable hominin species include Australopithecus, Homo habilis, Homo erectus, and Homo neanderthalensis.

Throughout the evolutionary process, hominins experienced numerous physical and behavioral changes, ultimately leading to the emergence of modern humans. Fossil records and genetic evidence have helped scientists reconstruct the complex and dynamic history of hominin evolution, revealing insights into our ancestors' lives and the environments they inhabited. In summary, the hominin line refers to humans and our ancestors/relatives after our split from the African apes, encompassing various species that developed unique traits and evolved over millions of years.
