Answers

Answer:

Mechanical waves react to different mediums in different ways. Some mechanical waves are TRANSMITTED through a medium, meaning they pass through the medium.

The way in which waves are transmitted depends upon the type of material. In SOLIDS, mechanical waves travel rapidly, because the molecules are DENSELY packed. In liquids and air, however, mechanical waves travel more SLOWLY, because the molecules are spread farther apart.

Other mechanical waves are reflected off a medium. When a mechanical wave is reflected, it BOUNCES off the medium and then travels in a DIFFERENT direction. SONAR is an application that uses sound wave reflection to determine how deep water is.

A third way mechanical waves react to a medium is ABSORPTION. When a mechanical wave is absorbed, it remains WITHIN a medium and is not transmitted to another medium.

What is the best explanation for the difference in shape between the two drops shown below

Answers

Answer:

A

Explanation:

I think the answer is A because Hexane is a non-polar solvent and A is the only answer choice that says its non polar. Im sorry if it is incorrect

The best explanation for the difference in shape between the two drops given in image is - Option D. glycerin is polar and has greater cohesion than hexane.

Polarity is the physical characteristics of liquid that allows them to stick to other substances which is called adhesion. Polar molecules also attracted to itself, and this physical trait called cohesion. Water's most common form in the air, a droplet is formed due to this cohesion.

Hexane is a nonpolar solvent that has less electro negativity charge therefore, they do not have hydrogen bonding and there is less cohesion in the molecules.Glycerin is a polar solvent that allows its molecules to attract itself that is cohesion present and lead to more of droplet shape.

Thus, the correct answer is - option D.

Answers

Answer:

The correct answer is - b. inadequate mineralization in the osteoid.

Explanation:

Osteomalacia is a condition where the bones become weak and soft, this bone softening is occurred due to mainly vitamin D deficiency that also causes rickets. It leads to insufficient or inadequate mineralization in the osteoid.

This conditing when takes place in kids and young adult leads to curve or bowing during the growth period. In this case, bones are very prone or easily fractured.

The idea of natural selection would in theory be affected by mutations because natural selection invloves a species/animal only surviving by having a certain trait.

What are the functions of proteins in cells and viruses?​

Answers

A viral protein is both a component and a product of a virus. Viral proteins are grouped according to their functions, and groups of viral proteins include structural proteins, nonstructural proteins, regulatory proteins, and accessory proteins.[1] Viruses are non-living and do not have the means to reproduce on their own, instead depending on their host cell's resources in order to reproduce. Thus, viruses do not code for many of their own viral proteins, and instead use the host cell's machinery to produce the viral proteins they require for replication

Answer:A adenine could hydrogen-bond with thymine and guanine could hydrogen bond with cytosine to hold the helix together

Explanation:

The double helix model of DNA explained Chargaff's rules because adenine could hydrogen-bond with thymine and guanine could hydrogen-bond with cytosine to hold the helix together. The correct option is A.

What is Chargaff's rule?

According to Chargaff's criteria, guanine and cytosine should be equal in amount in the DNA of every species and organism, and adenine and thymine should be equal in amount.

Additionally, the purine and pyrimidine bases should be in a 1:1 stoichiometric ratio.

The ratio of the several nitrogenous bases present inside the DNA molecule is described. It assists in figuring out the makeup and structure of DNA in various species.

Because adenine could hydrogen bond with thymine and guanine could hydrogen bond with cytosine to maintain the helix together, the double helix model of DNA provided an explanation for Chargaff's rules.

Thus, the correct option is A.

Answers

Net primary productivity is the amount of organic material that is available for transfer to the next trophic level after subtracting material used for respiration.

When a plant is eaten by a mouse, the mouse is consumed by a snake, and the snake is in turn consumed by a hawk. In this case, there will be less organic matter available.

Biomass change from lower to higher trophic levels by decreasing.

The incomplete burning of ethanol in gasoline is known to create black carbon and contribute to global warming.

There is less secondary consumers in an ecosystem than producers because there isn’t enough energy available to support more secondary consumers.

It should be noted that global warming brings about the increase in the temperature around the world.

Answers

Answer:

If the GENES of the parental mice encodes for a black fur, THEN the FUR COLOR of one of the offspring mice will be black.

Explanation:

Hypothesis is one of the steps used in the scientific method. It is a testable explanation of a given question or observation. Hypothesis in an experiment must be subjected to testing via experimentation in order to determine whether to reject it or not.

Hypothesis is usually constructed in the IF, THEN format. It tells us how the independent variable (cause) affects the dependent variable (outcome). In this case, a question is asked this: "what is the effect of the genes of the parental mice on the fur color of the offspring mice?"

A possible hypothesis will be: If the GENES of the parental mice encodes a black fur, THEN the FUR COLOR of one of the offspring mice will be black.

Answer:

A. If either parent mouse passes a dominant allele, the offspring will have black fur.

Either option is correct because it didn't show any green check. It determines on what hypothesis you wrote. I chose A because it relates to my statement. <33

If there will be changes on trophic levels, what will be the effects on the ecosystem?

Answers

Answer:

It can significantly alter the homeostasis of the ecosystem

Explanation:

The trophic level is the position that occupies a given organism/ population/species in the food web. In a food web, the trophic levels are organized into a first category (formed by primary producers, e.g., plants), a second level (primary consumers, e.g., herbivores), and subsequent categories (predators, e.g., carnivores). The abrupt change in the number of organisms belonging to the same trophic level generally has a negative effect on the ecosystem by modifying the trophic structure of communities. For example, decreasing the number of producers will produce a decrease in the number of primary consumers, thereby altering the homeostasis (equilibrium) of the entire ecosystem. On some occasions, it may eventually lead to the extinction of populations and species.

Answers

Answer:

seminiferous tubules

Explanation:

Seminiferous tubules are coiled tubes where sperm cells are produced by a process referred to as spermatogenesis. These tubes are located in the testes or testicles (i.e., male reproductive glands/gonads). Each testicle contains approximately 250 compartments known as testicular lobules, while each testicular lobule has 1 to 4 seminiferous tubules which converge to form a single straight tubule. Once sperm cells mature, they travel through the seminiferous tubules to be stored in a coiled tube called the epididymis.
