Describe 3 ways microbes are detrimental and 3 ways they are beneficial to humans.

Answers

Answer 1
Answer:

Answer:

Here are the 3 ways:-

Explanation:

  • Microbes are important for your skin, one of the body’s first lines of defense against illness and injury. Skin health depends on the delicate balance between your own cells and the microbes that live on its surface.
  • Microbes are important to the body’s infection-fighting immune system. In one recent study, NIH scientists examined special mice that were born and raised to be germ-free. These mice seemed to have weak immune function. In contrast, normal mice have vibrant bacterial communities and a rich variety of immune cells and molecules on their skin.
  • Microscopic creatures—including bacteria, fungi and viruses—can make you ill. But what you may not realize is that trillions of microbes are living in and on your body right now. Most don’t harm you at all. In fact, they help you digest food, protect against infection and even maintain your reproductive health. We tend to focus on destroying bad microbes. But taking care of good ones may be even more important.
Answer 2
Answer:

Final answer:

Microbes can be harmful by causing diseases, food spoilage, and creating biological toxins in humans. On the other hand, they can be beneficial by aiding in digestion, recycling nutrients in the environment, and aiding in the production of food and medicine.

Explanation:

Microbes, or microorganisms, are microscopic entities that can be beneficial or detrimental to humans in various ways.

Detrimental Effects of Microbes:

  1. Disease: Many microbes are pathogenic, meaning they can cause diseases in humans such as the common cold, influenza, pneumonia, and more severe diseases like tuberculosis and HIV/AIDS.
  2. Food Spoilage: Microbes can cause food to rot or spoil, leading to food wastage and also food poisoning if consumed.
  3. Biological Toxins: Certain microbes produce biological toxins that are harmful to humans. For instance, the bacteria Clostridium botulinum produces a potent neurotoxin leading to botulism.

Beneficial Effects of Microbes:

  1. Digestion: Microbes in our gut aid in digestion, and also synthesis B-vitamins and vitamin K that humans cannot produce on their own.
  2. Decomposition and Recycling: Microbes play a vital role in decomposing dead organic matter and recycling essential nutrients in the environment.
  3. Food and Medicine Production: Yeasts are used in bread and alcohol production, while other microbes are exploited to produce antibiotics and other medicines.

Which of the following forms an important component of phloem tissue?A. tracheids

B.
vessels

C. companion cells

Answers

Answer: The correct answer is- C) Companion cells.

Phloem tissue is a complex conducting tissue that is present in the vascular plants and responsible for the transport of organic compound such as carbohydrates and proteins from leaves to the rest part of the plant.

The various components of phloem tissue are- Sieve element, Companion cells, phloem parenchyma, phloem fiber.

Companion cells are specialized cells ( present in association of sieve element) that perform various metabolic reactions and responsible for cellular activities. They help in loading and unloading of carbohydrate into sieve element.      

C. Companion cells. THe vessels are for blood flow, Tracheids are elongated cells in the xylem of vascular plants that serve in the transport of water and mineral salts. 

Sustainable use of water as a natural resource in your community

Answers

Water is a limited natural resource, vital for the expansion and development of, not only our specie, but each individual living organism in the planet. Hence, in a community proper water management is a must in order to make sure that water be maintained and cared for -used wisely. In one research, it is estimated that by 2025 more places will feel water scarcity than decades ago. 

Identify the location and function of vascular cambium

Answers

The vascular cambium is a plant tissue located between the xylem and the phloem in the stem and root of a vascular plant. Its functions is for secondary growth. It makes new phloem towards the outside of the plant and new xylem towards the inside. Good luck!

The principle stating stating that the oldest rocks occur on the bottom of an undisturbed rock sequence is known as

Answers

The principle of Superposition states that, in an undisturbed sequence, the oldest rocks are at the bottom of the sequence and successive layers are younger than those below them. This is different from relative dating because, relative dating examines rock position in aq sequence to determine the order of events the rock's relative age.

Vanessa notices that even though her 80-year-old grandmother keeps her thermostat at 800 F, she still wears a sweater in her house. When Vanessa asks her grandmother why, her grandmother tells her she is very cold. Vanessa can’t understand this and asks you for an explanation. What would you tell her?

Answers

Answer:

As one age, the bodies become subtle to cold temperatures. This is generally due to decline in the metabolic rate. As one age, the bodies lose the tendency of producing sufficient heat to sustain the usual temperature of 98.6 degrees. In addition to this, thinning of the skin is another thing, which may contribute to the feeling of cold in older individuals.  

With age, the physical tendency of the body declines, and the body does not function as it used to earlier. A decline in temperature can make the older adults very cold, even if they are dressed warmly. There are various researchers, which shows that older individuals exhibit low body temperatures in comparison to the younger ones.  

Some of the factors that can contribute to cold sensitivity in older adults are:  

1. Poor metabolic rate

2. Loss of elasticity of the blood vessels.  

3. Low blood pressure

4. Thinning of the fat layer underneath the skin

5. Physical issues and exposure to cold water
