If you've been sitting in the hot Sun and start to sweat, your body responds from a _____. positive or negative feed back?

Answers

Answer 1

Answer: If you've been sitting in the hot sun and start to sweat, your body responds from a negative feedback.

Answer 2

Answer: The body responds from a negative feedback. Homeostasis is carried out in the human body under the principal of negative feedback, where changes are made in order to counteract the effect of a stimulus. For example, the stimulus is the sun and its effect is your body heating up. Therefore, by sweating, the body tries to reduce its temperature.

1. An advantage of light microscopes compared to electron microscopes is that light microscopes A)allow you to view living cells, while electron microscopes do not. B)allow you to view the surface of cells in greater detail than electron microscopes. C)have a higher magnification capability because they use natural light. D)have a greater resolution available because they use white light. 2. To study the details of protein molecules on the surface of a cell, a biologist would likely use a A) compound light microscope. B) dissecting microscope. C) scanning electron microscope. D) transmission electron microscope. 3. What would be the magnification of a specimen viewed with a compound light microscope that has an objective power of 40x and an ocular lens power of 10x? (2 points) 40x 50x 400x 500x

Answers

Answer:

1. The correct answer would be A) allow you to view living cells, while electron microscopes do not.

There are many advantages of light microscope over electron microscope such as:

It is easy to use as compared to the electron microscope.
It enables us to view both alive as well as dead specimen whereas electron microscope can be used to view dead specimen only.
Light microscopes are much cheaper and have much lower maintenance cost as compared to the electron microscope.

2. The correct answer would be C) scanning electron microscope

Scanning electron microscope or SEM is a type of electron microscope which is used to observe surface topography and composition of the specimen. It can achieve resolution of up to 1 nanometer.

3. The correct answer would be 400x

The total magnification of the microscope can be calculated by multiplying the powers of the objective lens and that of the eye lens.

Thus, the magnification of the specimen would be 40*10 = 400x.

1. The correct answer is A) allow you to view living cells, while electron microscopes do not. Light microscopes use visible light to illuminate specimens, which is less damaging to living cells compared to the electron beams used in electron microscopes.

The electron microscope

2. The correct answer is C) scanning electron microscope. Scanning electron microscopes (SEMs) are commonly used to study the details of protein molecules on the surface of cells. SEMs provide high-resolution images of the surface topography by scanning the specimen with a focused beam of electrons.

3. To calculate the total magnification of a compound light microscope, you multiply the magnification of the objective lens by the magnification of the ocular lens. In this case, the objective power is 40x, and the ocular lens power is 10x. Therefore, the magnification of the specimen viewed with this compound light microscope would be 40x * 10x = 400x. So, the correct answer is C) 400x.

if a horticulturist breeding gardenias succeeds in having a single plant with a particularly desirable set of traits, which of the following would be her most probable and efficient route to establishing a line of such plants?

Answers

The answer is to clone a plant asexually.

Cloning occurs naturally in some plants. Plants can clone themselves by asexual reproduction and, thus, produce identical copies of themselves. In asexual reproduction, there only one parent is necessary. There is no gamete fusion, no mixing of genetic information, so the offspring is genetically identical. So, after a horticulturist succeeds in breeding gardenias and wants to keep its line, it should clone it asexually. That way a particularly desirable set of traits will pass to all offspring.

Early organisms in the precambrian era converted ______ to oxygen.

Answers

Answer:

Early organisms in the precambrian era converted ___Carbon dioxide__ to oxygen.

Explanation:

THE PRECAMBRIAN ERA:

The word Precambrian means before the Cambrian period. Before the formation of oldest rock with having fossils in them this term was used to the whole period of earth's history.

This era gone through number of important changes. One important change is that atmosphere of this era is deprived of Oxygen. All other content of the atmosphere is same as component of air present today but with little water vapours. Early organisms in the precambrian era converts carbon dioxide into oxygen. This oxygen was very less and begins to combine chemically with iron and other elements. This produces great mineral deposits around the world. This is the era from where aerobic respiration organisms start their life cycles.

Carbon dioxide to oxygen.
This was the start of the evolution of photosynthesis, where carbon dioxide is broken down to its constituents, and the carbon is used for the synthesis of glucose to be stored in the organism as energy storage.

Which of the following is not true concerning tropical plantations?a. They are generally found in humid, tropical climates.
b. Wheat and corn are common products of tropical plantations.
c. Most crops from tropical plantations are exported.
d. Cocoa, coffee and tea are common products of tropical plantations.

Answers

The right option is; b.

Wheat and corn are common products of tropical plantations is not true concerning tropical plantations.

Tropical plantations is a type of agriculture in which perennial plants are grown for several years. Tropical plantations are usually practiced in regions with humid, tropical climates and plants such as cocoa, coffee, tea, coconut, rubber and oil palm are the common crops that are cultivated. The crops are mostly exported and they serve as important source of income. Wheat and corn are not common products of tropical plantations .
