Answer:c

Explanation:because cosin of b is c

(a cosc, b sinC) pairs represents the vertex A in this diagram. Hence option D is correct.

In geometry, a vertex (in plural form: vertices or vertexes) is a point where two or more curves, lines, or edges meet. As a consequence of this definition, the point where two lines meet to form an angle and the corners of polygons and polyhedral are vertices.

The vertex of an angle is the point where two rays begin or meet, where two line segments join or meet, where two lines intersect (cross), or any appropriate combination of rays, segments, and lines that result in two straight sides meeting at one place.

In a polygon, a vertex is called "convex" if the internal angle of the polygon is less than π radians otherwise, it is called concave.

Hence option D is correct.

Open system; can exchange both matter and energy; An example is a living organism such as human being, we actively interact with environment, which results in changes  to both the environment and human being, for instance we eat to acquire energy.

Closed system; can exchange energy but not matter; An example is a saucepan, the saucepan allows energy transfer as the saucepan heats up and heats the contents inside it, putting a lid on it, prevents matter from entering and becomes a closed system.

Isolated system; Can exchange neither energy nor matter. For example is a thermos. if tea is poured into a thermos or an insulated container there is no exchange of heat or matter.

Bacteriophages are a special class of viruses that infect and spread only within bacteria.

Bacterium refers to bacteria, while "phage" means to eat or devour. Together, these two words form the term "bacteriophage". Highly specialized viruses called bacteriophages attach to the surface of bacterial cells and introduce their genetic material into the host bacterium.

Once the bacteriophage's genetic material enters the bacterial machinery, it causes it to make multiple copies of the phage particles. The host bacterium is eventually killed, and freshly produced phages are freed to infect additional bacterial cells. Nature is full of bacteriophages, which are important for managing bacterial populations and building microbial communities.

Answer: Characteristics acquired during an organism's life are generally not passed on through genes.

Explanation:

The most common misconception between students which can be corrected is that the characteristics acquired during an organisms life are generally not passed on through the genes. Thus, the correct option is A.

Acquired traits or characteristics are the non-heritable changes in the function or structure of a living organism which is caused after birth and was absent before this. Occurrence of acquired traits could be due to disease, injury, accident, deliberate modification, variation, repeated use, or other environmental influence.

For example, the giraffe stretched its neck while reaching for the higher leaves but her children does not get a long neck by birth however this character has been fixed with time because of the repeated use of the neck for food.

The long term results of planting more genetically modified crops with an increased tolerance to insects are complex and multifaceted, and there are both potential benefits and potential risks that need to be considered.

One of the potential long term results of planting more genetically modified crops with an increased tolerance to insects is a decrease in the use of pesticides. This can have a positive effect on the environment, as there will be less chemical runoff into waterways and less potential for harm to non-target species.

However, there is also the potential for insects to develop resistance to the genetically modified crops, leading to a need for new methods of pest control.
Another potential long term result is an increase in crop yield, as the crops will be less likely to be damaged by insects. This can lead to a more stable food supply and potentially lower food prices.
However, there are also concerns about the potential impact of genetically modified crops on biodiversity and the potential for unintended consequences.

For example, there could be unintended effects on other species in the ecosystem or potential health risks for humans consuming the crops.

C. fruit flies. Scientists have successfully manipulated a single gene to control intimate orientation in fruit flies.

This groundbreaking research involved manipulating the fruit flies' version of the "fruitless" gene, which is involved in regulating courtship behavior and intimate orientation. By modifying this gene, scientists were able to influence the intimate  preferences of the fruit flies, causing them to exhibit same-gender attraction. However, it is important to note that the manipulation of a single gene in fruit flies does not imply that the same can be done in humans or other organisms. intimate orientation in humans is a complex trait influenced by a combination of genetic, hormonal, environmental, and social factors. While genetic factors may play a role in human intimate  orientation, it is not determined by a single gene and cannot be controlled or altered in the same manner as demonstrated in fruit flies.

a. capillary action of liquid in plant stems

Explanation:

Vascular plants need to transport water from roots to stem and leaves. For this purpose, water molecules adhere to xylem cell walls (xylem is one of the two classes of transport tissues in higher plants). Adhesion, also known as capillary action, is a mechanism produced when water molecules cling to xylem cell walls. Thus, adhesion can be defined as a molecular mechanism caused by the attraction between molecules, in this case, between molecules of the xylem and water molecules.

Answer:

First, we must understand:

What is Hydrogen Bonding?

Hydrogen Bonding is the interaction between Hydrogen atoms, with their molecules, due to the fact that their (Hydrogen atoms and bonds) are weak that even the other types of bonds are stronger.

(The other bonds are: covalent and ionic bonds)

(Hydrogen bonds are weaker than the average bonds listed above)

If you are to take how and why hydrogen bonds effect/affect ice cubes, we would have to look at how ice cube are formed. If you know, ice cubes can be created due to low temperatures (cold temperatures) making water into a solid. When ice cubes form into a sold, the spacing of the molecules become further apart, creating the density of the overall ice cube lighter than it was allowing it (ice cubes) to float.
