Answer: All fingers, toes, feet, and palms are covered in small ridges. These are raised portions of the skin, arranged in connected units called dermal, or friction, ridges. They help us with our grip on objects that we touch. When these ridges press against things, they leave a mark, an impression called a fingerprint.

Answer:

Their purpose on the body is to increase the surface area and increase friction so hands can firmly grasp things, and feet do not slip when walking.

The imprint of a fingerprint consists of natural secretions of the sweat glands that are present in the friction ridge of the skin

Explanation:

They help us with our grip on objects that we touch. When these ridges press against things, they leave a mark, an impression called a fingerprint.

Which organelles would create a basic protein that could be modified to move chromatids during metaphase?
bija089 [108]

The organelles would create a basic protein that could be modified to move chromatids during metaphase is the histine protien which is secreted from the RNA's.  

<u>Explanation:</u>

Histone protein is the protein that is associated with the chromosome. The chromatin fibres get condensed into chromosomes on these proteins.  

The chromatin fibre i.e. the DNA fibre gets to wrap itself around the histone octamer which is formed of two units of each of Histone H2A H2B H3 and H4. Then the H1 protein seals the turn and thus a chromosome is formed. These histone are produced in the S-phase of the cell cycle. This protein is transcribed into m-RNA's and then translated into protein.

A cell membrane that transports glucose, ions, or other charged or polar molecules is likely to have a higher percentage and gre
erica [24]

Answer: True

Explanation:

<u>A cell membrane consists of a lipid bilayer made of polar phosphate head and a nonpolar lipid tail.</u> It is semipermeable and regulates the transport of materials through it. For this,<u> it is selectively permeable</u> and since it is made of lipids, hydrophobic and small polar molecules can diffuse easily through it by simple diffusion and down their concentration gradient. However, polar molecules, large molecules (such as glucose) and ions are not able to pass through it because they are repelled.

To accomplish the transport of these molecules that can not diffuse, proteins embebbed in the membrane function as carriers that enable the transport of polar molecules, large molecules and ions by passive (through facilitated diffusion, down its concentration gradient) or active transport (movement against its concentration gradient).

ira [324]

Answer:

the correct order of events in the nutritional processing of this food is ingestion- digestion- absorption- egestion.

Explanation:

1.) Ingestion involves taking food, drink, or another substance into the body by swallowing to aid in digestion.

2.) Digestion involves the breakdown of large insoluble food molecules into small water-soluble food molecules so that they can be absorbed into the watery blood plasma.

3.)Absorption involves the in take of the digested food into the bloodstream

4.) Egestion involves the removal of undigested food substance from the body.
