What is the function of spines on cacti

Biology

soldier1979 [14.2K]2 years ago
8 0

The spines of the cactus have several functions, which are the following:

To defend them from possible predators: inside the body of the plants there is a great deal of water; if herbivores could access it, these plants would not survive.

To provide them with shade: it is true that not much, but it is enough so that the loss of water by evaporation is minimal.

Reflect sunlight: many species have white spines.

Which statements describe the effects of the solar wind on Earth? Check all that apply. The solar wind produces the northern and
Andrei [34K]

The correct answers are:

• The solar wind produces the northern and southern lights

• The solar wind disrupts communication systems.  

• The solar wind distorts Earth's magnetic field.

Solar winds are geomagnetic stream of charged particles radiated from the outer atmosphere of the sun. All planets are protected from solar winds via magnetic fields but planets that are positioned closer to the sun can experience degeneration of the magnetic field.

Solar winds are capable to distort and even destroy the functioning of communication satellites  in outer space, such as radio and tv communication and satellite based internet services.

The effects of solar winds that are visible to naked eye are the Aurora Borealis (the Northern lights) and the Aurora Australis (the Southern Lights).

Which level of biological classification do Mammalia and Hominidae represent, respectively?
cupoosta [38]
The answer is class and family.

<span>Taxonomic groups are used for biological classification. There are eight main taxonomic groups: domain, kingdom, phylum, class, order, family, genus and species, with the domain as the most inclusive and species as the least inclusive. If we take a look on Mammalia and Hominidae classification, we can assume that Mammalia represents class, and Hominidae represents family:</span>

<span>1. Domain: Eukarya</span>

<span>2. Kingdom: Animalia</span>

<span>3. Phylum: Chordata</span>

<span><u>4. Class: Mammalia</u></span>

<span>5. Order: Primates</span>

<span><u>6. Family: Hominidae</u></span>

<span>7. Genus: Homo</span>

<span>8. Species: Homo sapiens</span>

The process of lipid digestion begins even before you take your first bite of food. Just the smell of food can begin digestive j
ikadub [295]

Answer:

The given statements have been rearranged in the following order to depict the flow of events that account for lipid digestion in the human body:

  1. Mechanical digestion by chewing breaks food down.
  2. During digestion, gastric lipases break down fat into fatty acids and triglyceride molecules.
  3. Gastric lipase digests some triglycerides.
  4. The pancreas secretes gastric lipase into the small intestine, where the majority of fat digestion occurs.
  5. Lipid ­digesting enzymes from the pancreas break down the triglycerides into two free fatty acids and a monoglyceride.
  6. Lingual lipase is secreted from the pancreas and breaks down triglycerides.
  7. With the aid of pancreatic lipase, fats are further broken down into free fatty acids and monoglycerides.
  8. Products of fat digestion are packaged into micelles and transported to the enterocytes.

The process is started in the mouth. Action of the teeth physically breaks down the food and increases it surface area that allows for better access to it for the enzymes to carry out mechanical digestion. Gastric lipases are those in the stomach, most of the lipid digestion takes place in the small intestine with the help of enzymes secreted by the pancreas and the small intestine itself. After digestion, the final products are taken up by the lymphatic system.

Hope that answers the question, have a great day!
