Be-19 what must a type iii marine sanitation device have when boating on inland waters?

vekshin1

For the answer to the question above, I think that the A Type III Marine Sanitation Device must have a closed and secured Y valve when boating on inland waters.
I hope my answer helped. Have a nice day ahead.

Green plants need light in order to survive. Structures in the leaves absorb light, which in turn, helps plants make their own f

Lorico [155]

Answer:

The correct answer is the green light.

Explanation:

Plant themselves have a green color pigment in their leaves called chlorophyll which absorbs visible light.

Pigments absorb mostly the red and blue color light and reflect green light. This the reason why plants appear green to us and least likely to make food. Most of the autotrophs contain this green pigment.

Thus, the correct answer is the green light.

Which series of labels correctly identifies the indicated structures in this sketch of a cell viewed under a microscope?

juin [17]

Explanation:

B [A.Golgi apparatus B.nucleolus C.endoplasmic reticulum D.mitochondrion E.ribosome F.lysosome]

Cellular organelles comprise proteins parceled into membranes. These allow for storage of substances, and specialization of cell function.

Further Explanation:

Cells' structural components (i.e. their makeup) determine their function (what they do) . For instance, photosynthesizing cells in algae and plants have structures called chloroplasts. These contain chlorophyll, a specialized compound which facilitates the conversion of light energy to energy stored in carbohydrates.

In specific cell types, collected proteins may function as a unit called an organelle. Some organelles are bound by membranes like those that make up the external structure of the cell, with varying compositions of phospholipids and proteins. These are advantageous, as they:

may increase metabolic reaction efficiency; they allow cells to concentrates smaller fractions of enzymes and solutes such as the mitochondria
separate proteins and molecules that me harm the cell by parceling them into membrane-bound organelles for example, proteaseas bound within lysosomes can break down many structural proteins as seen in lysosomes

More specifically some organelles like vacuoles play a structural role in the cell; supports the cell membrane by exerting turgor pressure.

Other structures also play important support roles:

Nucleus: houses all the genetic information of the organism
most proteins that function in the cytosol nucleus (such as DNA polymerase) are synthesized by free ribosomes.
Cytoplasm: contains the cytosol, microfilaments and other support structures in the cytoskeleton; it holds parts of the cell together
Golgi apparatus: protein modification and parceling for export

Antibodies are composed of two types of peptides, heavy chains and light chains. One of the major classes of antibody molecules

timurjin [86]

Answer and Explanation:

a. form the antigen-binding site ⇒ both chains

The antigen-binding site is formed by one hypervariable region of the light chain (VL) and one hypervariable region of the heavy chain (VH). So, both type of chains contributes to antigen recognition.

b. contain multiple variable domains ⇒ none

Both chains - light and heavy - contain <u>only one</u> variable domain (VL and VH).

c. are found in the Fab fragment ⇒ both chains

The Fab fragment is composed of portions of both light and heavy chains: each portion contains one variable domain and one constant domain. The Fab fragment binds specifically the antigen.

d. are found in the FC fragment ⇒ heavy chains

The Fc region is composed of portions of heavy chains (CH² and CH³), so it contains constant domains.

e. contain only one constant domain ⇒ light chains

Each light chain contains one variable domain (VL) and one constant domain (CL).

f. contain multiple constant domains ⇒ heavy chains

Each heavy chain contains three constant domains: CH¹, CH² and CH³.

g. contain only one variable domain ⇒ both chains

Both light and heavy chains contain one variable domain. The difference is given by the number of constant domains: light chains have 1 constant domain while heavy chains have 3 constant domains.
