Why does the nose the feet and the tail of a rat have no hair

Answers

More efficient heat dissipation

Answer:

A rat's tail lacks hair or fur for two main reasons. The first is more efficient heat dissipation. Without insulating fur or hair, the tail can lose heat more easily. The second reason for the hairless nature of the rat's tail is grip. These reasons are the same for the feet, but for the nose it is to enhance smell.

List at least 10 ways to maintain health care at home / community.​

Answers

10 strategies for sustaining home or community-based healthcare are: consuming proper foods, maintaining a balanced diet, avoiding smoking and consuming alcohol, exercising on regular basis, taking necessary calories, Checking the blood pressure and other blood components on a routine basis, and using a mask or protection to prevent disease spread, and wash hands properly, maintain cleanliness in and outside the apartment, drink plenty of safe water.

Discussion about the strategies:

Consume a variety of foods, such as fruits, vegetables, legumes, nuts, and whole grains for healthcare.Limit your daily salt consumption to 5g, or roughly 1 teaspoon. It is simpler to do this by choosing low-sodium foods and by reducing the amount of salt, soy sauce, fish sauce, and other high-sodium condiments you use while cooking meals, removing salt from your meal table, avoiding salty snacks, and removing salt, spices, and condiments from your meal table.Less than 30% of our entire calorie consumption should come from fats. Necessary calories should be taken.There is no recommended safe amount of alcohol consumption. So, stay away from alcohol.The term "physical activity" refers to any skeletal muscle-driven movement that involves the use of energy. So, get moving.One term for high blood pressure is "silent killer". This is due to the fact that many people with hypertension could not be conscious of the issue as it might not show any symptoms. So be sure to check your blood pressure often.When you start to cough or sneeze, make sure your mouth is covered with a face shield or a tissue, and then dispose of it safely.Use bug repellent and dress in light-colored, long-sleeved shirts and slacks as a healthcare strategy. Use bed nets, door and window screens, and weekly cleanings to eliminate mosquito breeding grounds in your house.Take in a lot of clean water. Water-borne illnesses including typhoid, dysentery, hepatitis A, fever, and polio can spread through the use of contaminated water.The transmission of contagious diseases can be stopped by using clean hands. When the hands are obviously dirty, you should wash them by hand with soap and water or use an alcohol-based hand scrub.

How do monosaccharides combine to form polysaccharides?

by removing water (H2O) from the monosaccharide molecules

Answers

Monosaccharides combine to form polysaccharides by removing water (H2O) from the monosaccharide molecules. This is called dehydration.

Many monomers of monosaccharides combine to form polysaccharides. For example- many monomers of monosaccharide glucose combine to form starch, which is a polysaccharide. When molecules of monosaccharides combine, the removal of water molecules takes place. This reaction is called a dehydration or condensation reaction.First of all, a disaccharide is formed due to a condensation reaction in which two monosaccharides combine and a glycosidic bond is formed. Then, many condensation reactions take place between disaccharides, resulting in the formation of polysaccharides.

Hence, when several monosaccharides combine, they lose water, resulting in the formation of polysaccharides.

__ is a renewable form of energy that comes from plants

Answers

Answer:

Biomass

Explanation:

In most cases, it is organic waste. anything, including pig intestines, maize husks, and wood chips. The procedure can vary depending on what is burned specifically, but in a typical power plant arrangement, it is burned similarly to coal. Pollution (even if it is carbon neutral) and the plant's potential for intermittent feedstock supply, which reduces efficiency, are downsides. either carbon neutral or renewable In my opinion, it is renewable by definition. Although it is not carbon neutral, very little else is either. Solar and wind energy still have a carbon impact. Those still have a net gain even though they offset more carbon than their footprint (per current manufacturing). Although burning biomass has a positive carbon footprint, is it more carbon-neutral than burning coal and natural gas? Maybe. Burning biomass releases carbon dioxide into the atmosphere that has previously been stored. Through feedback processes, this sudden rise in carbon will lead to an increase in other GHGs. Cutting down young trees for this reason also eliminates a carbon sink, which doesn't replenish until 60+ years (or 100+ in certain cases). Other biomass sources have a quicker recovery time. It is possible for biomass to be net negative when combined with carbon capture. Its efficiency might be increased by using it directly for heating purposes. There are several factors to take into account while deciding whether to utilize it, such as which other sources it would actually counteract. Overall, it should be used sparingly and with continual consideration of the particulars.

6. Two different populations of similar organisms are considered separate species when they are _____ isolated.

Answers

When two populations of similar organisms are reproductively isolated, then we consider them as separate species.

Species are formed when there is reproductive isolation between the different populations of similar organisms. Reproductive isolation can happen due to several factors such as environmental problems and natural calamities. Sometimes, a barrier arises between the two populations due to which populations of similar organisms get separated and the individuals of each population reproduce within their population. With time, their genetic makeup changes and they become separate species. The two species can have many similar characteristics. But, they will have genetic variations. For example- Solanum tuberosum and Solanum melongena are two different species but they have some common characteristics.

Thus, when no reproduction occurs between the two populations from similar organisms, then they become different species.

How do limiting factors determine the carrying capacity of an ecosystem?Why is sod valuable? a. loses fertility c. prevents soil erosion b. loses topsoil d. causes soil erosion

Answers

Limiting factors affect the carrying capacity by limiting available resources and regulating population sizes. Sod is valuable because it prevents soil erosion. Option C.

How limiting factors affect the carrying capacity?

The carrying capacity is the capability of the environment to support a growing population. It might be affected by different factors, known as limiting factors.

Limiting factors might depend on population density or be density-independent.

Density-dependent factors → depend on the population size → intra- and interspecific competition or predation.

These factors are related to the interaction between populations and species. They might compete for resources (in which case resources become limited, affecting population sizes) or might establish a predator-prey relationship (in which case, predators and prey depend on each other and regulate their population size).

Density-independent factors → do not depend on the population size → Human impact or natural disasters (fires, volcanic eruptions, flooding).

Density-independent factors cause damage to the ecosystems, reducing the available resources such as food, water, or shelter and consequently decreasing the number of individuals. These factors reduce the carrying capacity of the environment.

In both cases, limiting factors regulate population size.

What is erosion?

Erosion is the fertile soil loss process that leads to its degradation. It is due to several external agents that damage the ground and drag the exposed material from the superficial layers.

All the erosive agents act together, altering the soil composition, shape, and structure.

Some erosive agents are water, wind, ice, gravity, and animal trampling.

The loss of natural plant cover aggravates the erosive effects since no plants are protecting the soil.

Soil plant cover reduces erosion because the aerial part of the plant protects the surface, while roots protect the ground structure and absorb water.

Several grass species develop large roots to establish themselves on the ground. This characteristic helps to reduce erosion and to keep soil humidity.

In conclusion,

Limiting factors regulate population size.Plant cover avoids erosion. So, the correct option is C. Sod is valuable because it prevents soil erosion.
