Answer:
In celiac disease, gluten triggers the immune system to damage villi. Villi (VIL-eye) are finger-like projections lining the small intestine that absorb nutrients from food and send them into the bloodstream. Damaged villi can't absorb the vitamins and minerals that a child needs to grow.

!!!!NEED HELP ASAP ILL GIVE BRAINLIEST AND 25 POINTS!!!!! How do proteins help transport of materials through the membrane?
Answer:
Channel proteins can aid in the facilitated diffusion of substances by forming a hydrophilic passage through the plasma membrane through which polar and charged substances can pass.
Explanation:
Answer: By forming a continuous protein pathway across the membrane, these proteins enable specific hydrophilic solutes to cross the membrane without coming into direct contact with the hydrophobic interior of the lipid bilayer. Carrier proteins and channel proteins are the two major classes of membrane transport proteins.

Explanation:
What three things might influence a slide when conditions are right? What types of material can make up a flow? (Site 1).
A slide can be influenced by friction, weight, and the angle of the slope. The materials that form flow generate less friction depending on the environmental conditions.
A slide is a movement that occurs when a fragment of soil/rock suddenly moves down a slope.
Slope stability is a factor influenced by the angle of the slope and the strength of the materials (e.g., rocks) on it.
The slide movement can ultimately be considered as a battle between friction versus gravity.

what role did the black death play in the decline of feudalism
Answer:
The Black Death brought about a decline in feudalism. The significant drop in population because of massive numbers of deaths caused a labor shortage that helped end serfdom. Towns and cities grew.

Beaches are monitored to protect public health. Waterborne pathogens can cause illnesses. Which of the following is not a common type of pathogen at the beach?
Bacteria
Protozoa
Viruses
Worms
ALL these microorganisms can represent common types of pathogens at the beach. In consequence, it is imperative to take precaution measures to avoid infections.
The sand at the beach may contain dog feces, which is known to transport Toxocara canis, a parasite roundworm able to infect humans.
Moreover, samples of beach sand may also contain different types of pathogenic bacteria (e.g., Staphylococcus species, E. coli, Enterobacteriacea, etc) and viruses (e.g., enteroviruses, hepatitis A, Norwalk viruses, reoviruses, rotaviruses, etc).
In consequence, it is imperative to wash hands with soap and water when touching beach sand that is suspected to be contaminated.
Finally, marine water may also be contaminated with different zoonotic protozoa such as, among others, Giardia, Cryptosporidium and Toxoplasma.

within a forest ecosystem, there is a large amount of diversity among members of a warbler species. of the following stages of meiosis illustrated for a typical cell, which contributes most to diversity among the warblers?
Crossing over occurs between homologous chromosomes, and is closely involved in genetic variation. The stage that most contributes to diversity is stage C, where you can see chromosomes after crossing-over.
----------------------------
There are different mechanisms involved in producing genetic variation among descendants. These are,
Crossing-over between homologous chromosomes (prophase 1), Random lining of homologous chromosomes (metaphase 1),Random fertilizationThe Crossing-over events occur between two homologous chromosomes in the equatorial plane and make the daughter cells genetically different from the original one.
The Chiasma is the position where two homologous chromatids interchange genetic information, giving a place for new genetic material or information to be provided to descendants.
After crossing over, homologous chromosomes get separated again.
In the attached imaged there are four different stages of meiosis.
Stage C is the one that contributes the most to diversity.
We can see that crossing over has already occurred between homologous chromosomes, and they have already interchanged segments.
In the image you will see the difference between chromosomes that has gone through the crossing over mechanism, and chromosomes that has not. The difference in color represents segments interchange and variation.

is the DNA in the form of chromatin or chromosomes when a cell finished cytokinesis
Answer:
Cell cycle consists of interphase and mitosis. During interphase there are 3 phases- G1, S and G2 phases. G1 is the resting phase after previous mitotic phase, S phase is DNA synthesis phase and G2 phase is again resting phase.
DNA synthesis occurs before mitotic phase which is the actual cell division phase and chromosomes are condensed during mitotic phase therefore it's in the chromatin form that DNA is synthesised.
