Answers

Answer 1

The expansion of the universe

Answer 2

Answer:

Cosmic Microwave Background (CMB) radiation was discovered in the year 1965

Explanation:

The Cosmic Microwave Background (CMB) are a type of electromagnetic radiation which were believed to be the remnant of thermal energy from the big bang. Soon after the big bang explosion, the universe started to form and the CMB radiations were extensively radiated in all the direction. The universe then started to inflate rapidly and expanded. This expansion of the universe is still continuing. The CMB is very important because it helps in determining how the universe started to form in its initial time. These CMB radiations describes about the composition as well as the age of the universe.

Which does the work of the immune system? A. Enzymes B. Hormones C. Lymphocytes D. Neurons

Answers

Answer: C.Lymphocytes

Reasoning: Lymphocytes- a group of small white blood cell with a single round nucleus.

The definition of the word should tell it, referring to the fact white blood cells are the key to the immune system.

The correct answer is option C.The immune system is primarily dependent on lymphocytes to carry out its functions, which include recognizing and destroying pathogenic invaders and malignant cells. Lymphocytes, including B cells and T cells, are essential for the adaptive immune response, while macrophages and natural killer cells play critical roles in the innate immune response.

The correct answer to which does the work of the immune system is C. Lymphocytes. Lymphocytes are a type of white blood cell that are a key component of the immune system. Their main function is to identify and help destroy infectious invaders such as viruses and bacteria.

Lymphocytes are responsible for the specific immune response which is essential for long-term protection against diseases. There are mainly two types of lymphocytes involved in the immune response: B cells and T cells. B cells are responsible for producing antibodies that bind to specific antigens on pathogens, marking them for destruction, while T cells destroy infected host cells, coordinate the immune response, and help activate B cells.

Macrophages, which are part of the innate immune system, can phagocytize pathogens and produce chemicals that promote inflammation. Furthermore, natural killer cells, a part of the innate immune response, use MHC I molecules to identify and destroy compromised cells.

Which of the following occurs as a cell decreases in size?

1Points
A
The surface area volume ratio increases.

B
The surface area increases.

C
It is more difficult to transport waste and nutrients in the cell.

D
The volume increases.

Answers

My answer will be option A. "The surface area volume ratio increases.This is because, with normal growth, the cell gets bigger and bigger and its speed of waste production and its need to obtain resources increase faster than the surface where it is supported This explains why large organisms must consist of many small cells: cells are small in volume to maintain a large surface-to-volume ratio.

Correct answer: A). The surface area volume ratio increases.

A cell is like a compartment where various types of chemical reaction occur, like any living thing it also grows and increases in size. The higher the volume of the cell the larger reactions can occur in the cell. It means that higher surface area will allow a large exchange of substances through the cell.

If the size of the cell is decreased, it means its surface area to volume ratio also decreases, but at unequal rates. The volume would decrease faster as compared to the surface area which will lead to an increase in the surface area to volume ratio.

Hence, as the cell size decrease, the surface area to volume ratio increases.

Is it true of false that a disease that wiped out the rabbit population in an enviorment would affect the coyote population in the same environment?

Answers

This question has an awkward wording, however, the answer is yes.

Obviously, if the rabbit population decreases, so will the coyotes. Because, in assumption, the coyotes rely on the rabbits for food for survival.

Another answer can be yes and no, because if we are talking about the same disease, the disease can probably only target this specific species (rabbit), and the coyotes will not be affected. Or it might spread to any other animal available. Then again, both species are affected and will decrease.

what is the unemployment rate if the number of unemployed people is 19 and the labor force is 300

a. 6.3%

b. 7.1%

c. 5.9%

Answers

The unemployment rate can be calculated by dividing the number of unemployed people (19) by the labor force (300) and multiplying by 100, resulting in a) 6.3%.

The unemployment rate is defined as the number of unemployed persons divided by the total labor force, expressed as a percentage.

To determine the unemployment rate, follow these steps:

Take the number of unemployed people: 19Take the total labor force: 300Divide the number of unemployed people by the total labor force: 19 / 300 = 0.0633Convert the result to a percentage by multiplying by 100: 0.0633 * 100 = 6.33%

Hence, the correct answer is a) 6.3%.

c. do not vary; genetic factors alone determine early motor development
d. do not vary; environmental factors alone determine early motor development

Answers

A.vary somewhat; genetic factors can slow or accelerate early motor development.

Children's motor skill development times vary across cultures due to environmental factors, not solely genetic ones.

The fact that children in different cultures vary somewhat in the age at which basic motor skills appear demonstrates that environmental factors can slow or accelerate early motor development. This is supported by research indicating that while there are universal sequences of development, such as in language milestones, the timing of motor skills like sitting, crawling, and walking can differ due to varying cultural practices and childcare. For instance, in the Aché society of Paraguay, children typically start to walk later than those in Western cultures because they are carried more frequently to ensure their safety in the forest environment. However, as they grow older, their motor skills develop to surpass those of children in the U.S.

Final answer:

The protein in eggs denatures at 60-70 degrees Celsius, while the protein in milk denatures at 70-80 degrees Celsius. Hair protein typically denatures at temperatures above 150 degrees Celsius. Proteins denature at different temperatures due to their unique structures and compositions. Denaturing proteins can be useful in cooking and research applications.

Explanation:

The protein in eggs denatures at a temperature of around 60-70 degrees Celsius. You can tell that the protein has denatured because the appearance of the egg white changes from clear to opaque white as it cooks.



The protein in milk denatures at a temperature of around 70-80 degrees Celsius. You can observe the denaturation of milk protein by noting a change in the appearance, color, and texture of the milk as it heats up.



The temperature at which hair protein denatures can vary, but it typically occurs at temperatures above 150 degrees Celsius. You can tell that the protein in hair has denatured by observing changes in its appearance and texture, such as a change in color or a brittle texture.



Proteins denature at different temperatures because each protein has a unique structure and composition. The stability of a protein's structure depends on the specific interactions between its amino acids, which can be affected by factors like temperature and pH. Some proteins are more heat-tolerant and have adapted to function at higher temperatures, while others are more sensitive and denature at lower temperatures.



Denaturing a protein can be useful in a variety of contexts. For example, denaturing proteins in food during cooking helps to improve their digestibility and enhance their flavor. In research and biotechnology, denaturing proteins can help to study their structure and function, or to isolate specific protein components.

B-Water from the bottom of the lake raises and provides oxygen to the cooler waters on the surface.

C- Cool water at the surface traps nutrients deep in the lake to provide food during the winter.

D-The water in contact with the air sinks and mixes with the less oxygenated water in the deeper levels.

Answers

Answer:

C- Cool water at the surface traps nutrients deep in the lake to provide food during the winter.

Explanation:

As the fish have the ability to adapt to the changing temperature and they are generally are cold-blooded animals and the colder temperatures mean a reduction in the metabolic rates of the fish and this slow the numerous process of the digestion, feeding activity and thus they are often classified as cold, warm freshwater species. Atmospheric oxygen is needed for them to survive in the cold and they feed on the planktons and take the nutrients and the minerals from the surface of the and there don't remain so active as the period of the summer and the spring months.

In autumn, cool temperatures cause fall turnover in lakes, where cold surface water sinks and mixes with bottom waters, redistributing oxygen and nutrients which are crucial for fish and other organisms to survive through the winter. Option D) which is The water in contact with the air sinks and mixes with the less oxygenated water in the deeper levels is correct answer.

During autumn, as air temperatures drop, the water in lakes cools down, reaching a temperature of about 4 °C, which causes fall turnover. This process involves the heavy, cold water sinking and displacing the water at the bottom, leading to a mixing of the lake's waters. As a result, the oxygen-rich water from the surface descends to the bottom, while nutrients from the lake's bottom are brought up to the top.

This vertical circulation is crucial because during winter, the oxygen at the bottom is necessary for the survival of organisms, particularly fish and decomposers. Additionally, the ice forming on the surface of the lake helps insulate the water beneath, ensuring the survival of aquatic life through the cold season. option D) is the correct answer.

describe how sodium atom forms a bond with a chlorine atom

Answers

The sodium atom loses an electron and becomes positively charged. The chlorine atom gains an electron and becomes negatively charged. The two charged ions then form an ionic bond. Hope this helps

Even though sodium has a proclivity to lose an electron and chlorine has a proclivity to gain an electron, the components are well suited to bond with one another. This electron transfer results in the formation of the ionic bond that holds Na+ and Cl- together.

What is ionic bond?

Ionic bond, also referred to as electrovalent bond, is a type of interconnection established in a chemical compound by the electrostatic attraction of oppositely charged ions.

When the valence (outermost) electrons of one atom are permanently transferred to another, a bond is formed.

An ionic bond is formed when a metal and a nonmetal interact, whereas a covalent bond is formed when two nonmetals interact.

Despite the fact that sodium has a tendency to lose an electron and chlorine has a tendency to gain an electron, the components are well suited to bond with one another.

The formation of the ionic bond that holds Na+ and Cl- together is the result of this electron transfer.

Thus, this way sodium atom forms a bond with a chlorine atom.
