The state of a medium helps determine the speed of sound passing through medium

Answers

True. The speed at which sound travels through a medium is determined by the properties of that medium.

What do you mean by sound?

Sound is a type of energy made by vibrations that travel through the air or another medium, like water. It is sensed by our ears and interpreted by our brains. Sound is made up of waves that have different frequencies, which determine the pitch and loudness of a sound.

Factors such as temperature, pressure, composition, and density can all affect the speed of sound in the medium. For example, sound travels faster through warmer air than through colder air, and faster through denser materials than through less dense materials.

Hence, the statement is True.

The test tube that contained cream+ lipase+ bile contains all components necessary for optimum fat digestion.

What are fats?

Fats are lipid molecules of animal origin which usually are on solid form.

Fats are hydrophobic and serve as large energy stores in the body of animals.

The enzymes involved in fat digestion are known as lipases.

During fat digestion, They are first emulisified by bile before action by lipases.

Cream contains fats and are first emulsified before action by lipases.

Therefore, the test tube that contained all components necessary for optimum fat digestion is the one that contains cream+ lipase+ bile.

Answers

This information might be used to draw the conclusion that there will be fewer plankton in the region than is typical both as a carbon source and sink, hence B is the appropriate response to this question.

What is phytoplankton?

The kind of organisms that live in watery habitats are known as phytoplankton.

These species are autotrophic in nature and are the producers of this ecosystem. These creatures share a characteristic with terrestrial plants in that they both contain chlorophyll.

Therefore, if the phytoplankton population falls in the coming year, it means that the region's carbon supply and sink will be less than anticipated.

17. If most other species on Earth aren't monogamous, why are humans expected to be?

Answers

Many species are. Specifically, those species in which the male invests a significant amount of energy and time in providing for the offspring (rather than just fertilizing the female’s eggs and leaving). Humans definitely fall into the category. However, humans (like other monogamous animals) display what is called a “mixed strategy,” whereby each member of the pair tries to monopolize the parental investment of the other parent (to improve the chances for survival of their own offspring) while also remaining alert to (for males) sexual/reproductive opportunities with other females, or (for females) the chance to get resources (in the form of food, protection, etc.) from other males.

Of course, human cultural developments over thousands of years have shaped many variations on this basic theme. But the basic underlying logic remains the same. As evolutionary biologist Lynne Saxon put it, “monogamy is a compromise in which the winners are the offspring.”

That said, monogamy is by no means the rule across our entire species. In fact, a majority of societies around the world at least ALLOW men to have more than one wife. (A few allow women to have more than one husband.) The societies that allow for polygamy tend to be smaller than the ones where monogamy is the ideal, leading to a mistaken impression that our whole species is monogamous. But in fact, humans have devised a number of different sexual/reproductive strategies, across different cultural settings. Often it’s monogamy, for the simple reason that monogamy usually gives children the best chance of survival.

which of the following structures in a plant cell is responsible for the production of food​

Answers

Answer:

chloroplast

Explanation:

Chloroplasts are specialized organelles found only in plants and some types of algae. These organelles carry out the process of photosynthesis, which turns water, carbon dioxide, and light energy into nutrients from which the plant can obtain energy. There can be over one hundred chloroplasts in certain plant cells.

Chloroplasts are disk-shaped organelles that are surrounded by a double membrane. The outer membrane forms the external surface of the chloroplast and is relatively permeable to small molecules, allowing substances entry into the organelle. The inner membrane lies just beneath the outer membrane and is less permeable to external substances.

Between the outer and inner membrane is a thin intermembrane space that is about 10-20 nanometers wide. The center of the chloroplast that is enclosed by the double membrane is a fluid matrix called the stroma (you can think of this like the cytoplasm of the chloroplast).

Within the stroma, there are many structures called thylakoids, which look like flattened disks. Thylakoids are stacked on top of one another in vascular plants in stacks called grand. Thylakoids have a high concentration of chlorophyll and carotenoids, which are pigments that capture light energy from the sun. The molecule chlorophyll is also what gives plants their green color.

Do the patterns of interactions between organisms, such as competition and predation, change when they occur in different ecosystems

Answers

Yes, there is change when they occur in different ecosystems because each ecosystem contains a different set of abiotic and biotic features that interact with each other.

What is competition?

Competition is defined as the struggle for survival that exists between two similar organisms in an ecosystem where one who gains survives and the one that loses dies.

Predation is defined as the feeding interaction that exist between organisms whereby the one organism, the predator, kills and eats another organism, its prey.

Which of the following events would decrease competition for resources in an ecosystem?
A- a fire has killed off a portion of the vegetation
B- a drought reduces the amount of water available to an ecosystem
C- a disease reduces the population of rabbits in a grassland area
D- many offspring are produced in a single year

Answers

Answer:

C. A disease reduces the population of rabbits in a grassland area

Explanation:

If a disease reduces the size of a rabbit population, there will be a decreased amount of competition for resources.

Less rabbits means that there will be less competition, since there will be more food available.

For example, there would be less competition in a rabbit population of 10 rabbits compared to one of 20 rabbits. This is because there are less rabbits competing for food.

So, the correct answer is C. A disease reduces the population of rabbits in a grassland area

The events that would bring decrease competition for resources in an ecosystem is C. A disease reduces the population of rabbits in a grassland area.
