Answer:

D. Lichen will colonize the bare rock

Explanation:

When a glacier recedes and exposes the bare rock, it is likely that the lichen will colonize that rock.

Lichens have a wide distribution and inhabit the most different regions. Usually, lichens are pioneer organisms in a place, as they survive in places of great ecological stress (locals of extreme cold, for example). They can live in places such as rock surfaces, leaves, soil, tree trunks, alpine peaks, etc.

The lichen's ability to live in places of high ecological stress is due to its high drying capacity. When a lichen dries out, photosynthesis is interrupted and it does not suffer from high lighting, water scarcity or high temperatures. Because of this drop in photosynthesis, lichens have a low growth rate.

Which part of the microscope is used to make small adjustments in the image of an object?
Rus_ich [418]

Answer:

The part of the microscope that is used to make small adjustments in the image of an object is the fine adjustment.

Explanation:

In the optical microscope, the fine adjustment knob allows precise focusing of the sample being studied.  This means making minimal adjustments in order to better observe the microscopic image.

After the initial focusing with the coarse adjustment knob, with the fine adjustment it is possible to highlight the details that require more attention, as well as the refringency of the sample, if it exists.

The other options are not correct because:

<em>     A. </em><em><u>Eyepiece</u></em><em>  is the lens that receives the image from the objective lens, that has contact with the eyes of the observer.</em>

<em>     C. </em><em><u>Coarse Adjustment  </u></em><em>is the rough magnification, used for the initial approximation of the image.</em>

<em>     D. </em><em><u>Objective lens</u></em><em> enlarges and defines the image of the sample on the slide.</em>

Photosynthesis still occurs but the amount of red pigment is greater than the amount of green pigment. The chlorophyll still absorbs light energy. The red leaves does not affect the process of photosynthesis.

Fudgin [204]

Full Question:

Consider the two types of sudoriferous glands. Then click and drag each label into the appropriate category to determine whether it applies to apocrine glands, merocrine (eccrine) glands, or both.

-Not active until puberty

-Use myoepithelial cells to secrete

-Secrete sweat

-Found in pubic and axillary regions

-Secrete pheromones

-Abundant on hands, feet, and forehead

-Found over entire body

-Scent is meant to attract a potential male

-Thermoregulation

-Utilize ducts to release sweat

<h2><u>Answer:</u></h2>

Apocrine Glands:

-Not active until puberty

-Secrete pheromones

-Found in pubic and axillary regions

-Scent is meant to attract a potential male

Merocrine Glands:

-Found over entire body

-Thermoregulation

-Abundant on hands, feet, and forehead

Both Apocrine and Merocrine Glands:

-Secrete sweat

-Use Myoepithelial cells to secrete

-Utilize ducts to release sweat

<h3><u>Explanation:</u></h3>

The apocrine and merocrine glands are the subcategories of the sudoriferous glands which secrete the different types of secretions like sweat and oils. Both of them have myoepithelial cells.

The apocrine glands are mainly dependent on the sex hormones and are mainly present in the public region, beard etc. The sweat secreted from these glands are rich in fatty acids and other pheromones. These glands are regional in nature. But the merocrine glands are not hormonal in nature. They are distributed all over the body and secrete sweat whose primary function is to lower body temperature.
