Which sugar or sugars are broken down by lactase? How do you know?

Describe compliance with public health statutes:

quester [9]

Answer:

Answer is A. Communicable disease.

Explanation:

The activity of the public health which is known to be the core or major function is the minimizing or stopping the spread or transmission of communicable or infectious diseases.

A communicable or infectious disease is a disease that can be transmitted from an infected person to other people that not infected. This usually occurs through body contacts, unprotected sexual intercourse, unscreened blood transfusion, sharing of unsterilized sharp objects among others.

Elena-2011 [213]

The answer to the question mentioned above is the "Chloroplast".

During the light-dependent reaction of photosynthesis, chloroplast is decomposed to supply hydrogen ions tp produce NADPH, and important energy-carrying molecule used to help produce glucose during the light dependent reaction.

4. A single-celled organism that a student observed under a microscope is shown below.

Katyanochek1 [597]

Explanation:

D. The organism is eukaryotic because it has membrane-bound organelles.

Cells are the basic microscopic units of all organisms. There are two cell types, Prokaryotes and Eukaryotes.

Prokaryotic ( meaning pro: before and Karyon: for kernel/nut) describes organisms which don’t have a cell nucleus or other organelles surrounded by membranes. Eukaryotic (eu meaning true), are organisms with a cell nucleus and several other organelles surrounded by membranes. Example prokaryotes do not contain: nuclei , Golgi apparatus, chloroplasts, mitochondria

Both may contain a cell wall (seen in eukaryotic fungi and plant cells)

Arranged in a phospholipid bilayer, the membrane is semi-permeable; allowing entry into the extracellular fluid or the cytoplasm which are both hydrophilic and contain large concentrations of polar water molecules or other water-soluble compounds. The hydrophilic heads of the bilayer are attracted to water while their water-repellent hydrophobic tails face towards each other- allowing molecules of water and hydrophilic molecules to move across the membrane along the concentration gradient.

Their 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
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

which of the following levels of protein organization shows the complete 3D arrangement of the polypeptide chain

kherson [118]

Proteins are the macromolecules made of hundreds of amino acids. Proteins are most varied class of biological molecules and show the greatest variety of structures. Many have detailed three-dimensional folding patterns that result in a compact form, but others do not fold up at all and they are in random conformations. The function of proteins depends on their structure.

The secondary structure of protein fold together to form the 3D arrangement of a polypeptide chain that results into Tertiary structure which is a functional protein.
