What pigment traps the energy?
Vadim26 [7]
The pigment that traps energy is Chlorophyll. Chlorophyll is a green pigment commonly found in almost all plants, algae and cynobacteria. Leaves appear green because they contain this pigment. This pigment absorbs the light energy from the sun to complete the process of photosynthesis or food production of plants. Chlorophyll is said to absorb light in the long wavelength and blue in the short wavelength regions of the visible light spectrum. Green light is not absorbed, thus making the leaves of some plants green. Chlorophyll is found at the plant’s chloroplasts, which comes to have different structures.

Can someone please help me I need MAJOR help so I have this science test that counts for 60% of my grade but I can't find any in
Vesnalui [34]

-It's E-Coli, but it's scientific name is what you said, "Diarrheagenic Escherichia Coli"

-Nausea, Vomiting, Stomach Cramps, Bloody Diarrhea (Ew, I know), Fever (101 F, 38.3 C), Malaise, Dehydration, Loss of appetite

-All age groups can be affected by E Coli, but the elderly and the young can be the most at risk

-Wash your food, keep it clean, keep raw meats away from other foods to avoid cross-contamination, do NOT defrost meat on table tops or counters

-Symptoms last 5-10 days, staying hydrated and staying rested helps you;  Antidiarrheals should NOT be taken, but Antibiotics taken in portions, like Trimethoprim or Sulfamethoxazole are fine, although e-coli is known to go away on its own.

Which capillary would be least likely to allow substances to enter or exit the blood due to tight junctions that join the endoth
vodka [1.7K]

Answer:

Those capillaries that have endothelial cells tightly attached have an increase in cell-to-cell junctions, such as desmosomal junctions that are poorly permeable to substances.

These capillaries generally function as conductors or collectors and not as permeabilizers like the pulmonary capillaries that are fenestrated and allow a high passage of substances and gases.

The capillaries are waterproof and prevent the passage of substances or fluids such as in the blood-brain barrier that is very selective

Explanation:

The blood-brain barrier is too selective since it is not favorable for the organism that many fluids, drugs, substances or chemical compounds enter the brain space.

This is the reason why the vessels are waterproof and why pharmacology was challenged to invent drugs that could cross this barrier since it was considered impossible.

An example is dopamine, which in parkynson's disease the levo group is added to dopamine, thus forming levodopamine as a product, this is the only way that the drug crosses the blood-brain barrier and can pass the impermeable barrier generated by capillaries with endothelial cells that are close to each other or closely linked
