Answer the following question given this paragraph: From gametogonium (plural, gametogonia ), male and female gametes develop differently - males by spermatogenesis and females by oogenesis. A gametogonium is a germ cell that divides into gametocytes during gametogenesis. Male gametogonia are called spermatogonia , and female gametogonia are called oogonia . However, the following pattern is common for both oogonia and soermatogonia (chromosome numbers depict human chromosomes):. Q: What is a germ cell that divides into gametocytes during gametogenesis? Choices: - cocklebur - gonads - pollenation - gametogonium A:
gametogonium

Ques: Answer the following question given this paragraph: Malaria is common in tropical and subtropical climates throughout the world (see Figure below ). In fact, malaria is one of the most common infectious diseases on the planet. Malaria is also a very serious disease. It kills several million people each year, most of them children. Q: What type of climates is malaria commonly found in? Choices: - tropic and arctic - tropical and permafrost - arid and arctic - tropical and subtropical A:

(Q).
Answer the following question given this paragraph: Hundreds of thousands of asteroids have been found in our solar system. They are still being discovered at a rate of about 5,000 new asteroids per month! The majority are located in between the orbits of Mars and Jupiter. This region is called the asteroid belt , as shown in Figure below . There are many thousands of asteroids in the asteroid belt. Still, their total mass adds up to only about 4 percent of Earth's Moon. Q: What two planets is the asteroid belt found between? Choices: - mars and venus - earth and venus - saturn and uranus - mars and jupiter A:
(A).
mars and jupiter
Ques:Answer the following question given this paragraph: When we run a reaction to produce a gas, we expect it to rise into the air. Many students have done experiments where gases such as hydrogen are formed. The gas can be trapped in a test tube held upside-down over the reaction. Carbon dioxide, on the other hand, sinks when it is released. Carbon dioxide has a density greater that air, so it will not rise like these other gases would. Q: Carbon dioxide does not rise like other gases because it has a density greater than what? Choices: - gravity - light - water - air A:

Ans:air
Answer the following question given this paragraph: When a solid substance is involved in a chemical reaction, only the matter at the surface of the solid is exposed to other reactants. If a solid has more surface area, more of it is exposed and able to react. Therefore, increasing the surface area of solid reactants increases the reaction rate. For example, crushing a solid into a powder exposes more of the substance to other reactants. This may greatly speed up the reaction. You can see another example in Figure below . Iron rusts when it combines with oxygen in the air. The iron hammer head and iron nails will both rust eventually. Which will rust faster?. Q: When a solid substance is involved in a chemical reaction, only the matter from which part of the solid is exposed to other reactants? Choices: - the top - the base - the interior - the surface A:
the surface
