After trapping prey, spiders eat by releasing digestive enzymes that liquefy food and make it easier to swallow.
Answer: Rh boold factor is determined by the presnce or absence of a particular erythrocyte protein
Explanation:
The Rh factor is an integral protein of the membrane of red blood cells (erythrocytes) and, by its determination, the blood type RH + or RH- is detected, -regardless of the types of groups known as 0, A, B and AB- .
People who are RH + are those who have this protein in their red blood cells, and people with RH - refer to those who do not have the protein.
The Rh factor (Rhesus) was discovered by Karl Landsteiner and Wiener in 1940.

<span>Carbon dioxide is a colorless and odorless gas that is vital to life on Earth. This naturally occurring chemical compound is made up of a carbon atom covalently double bonded to two oxygen atoms. Carbon dioxide exists in Earth's atmosphere as a trace gas at a concentration of about 0.04 percent by volume. Natural sources include volcanoes, hot springs and geysers, and it is freed from carbonate rocks by dissolution in water and acids. Because carbon dioxide is soluble in water, it occurs naturally in groundwater, rivers and lakes, in ice caps and glaciers and also in seawater. It is present in deposits of petroleum and natural gas.</span>
Answer:
c) Ribosomes on the rough endoplasmic reticulum; Golgi apparatus
Explanation:
Endoplasmic reticulum, a member of endomembrane system. If it contains ribosomes on their surface, they are called Rough Endoplasmic Reticulum (RER). RER is the site for protein synthesis.
Newly formed protein undergoes modification, one such modification is the addition of carbohydrate side chains to form glycoprotein. The protein then moves to the Golgi for modification.
