Answer the following question given this paragraph: Seminiferous tubules can be seen in a cross section of a testis pictured in Figure below . The tubule is lined with spermatogonia, which are diploid, sperm-producing cells. Surrounding the spermatogonia are other cells. Some of these other cells secrete substances to nourish sperm, and some secrete testosterone, which is needed for sperm production. Q: What is secreted by the cells surrounding spermatogonia to help sperm production? Choices: - estrogen - dihydrotestosterone - follicle stimulating hormone - testosterone A:
(Answer)
testosterone
Ques: Answer the following question given this paragraph: Because of global climate change, temperatures all over Earth are rising. However, the melting points of Earth's substances, including ice, are constant. The result? Glaciers are melting at an alarming rate.

Ques:Answer the following question given this paragraph: The properties that chemists use to describe matter fall into two general categories. Physical properties are characteristics that describe matter. They include characteristics such as size, shape, color, and mass. Chemical properties are characteristics that describe how matter changes its chemical structure or composition. An example of a chemical property is flammabilitya material's ability to burnbecause burning (also known as combustion) changes the chemical composition of a material. Q: What type of properties are characteristics that describe matter? Choices: - visible - thermal - invisible - physical A:

Answer the following question given this paragraph: Insectivorous Plants An insectivorous plant has specialized leaves to attract and digest insects. The Venus flytrap is popularly known for its insectivorous mode of nutrition, and has leaves that work as traps (Figure 31.16). The minerals it obtains from prey compensate for those lacking in the boggy (low pH) soil of its native North Carolina coastal plains. There are three sensitive hairs in the center of each half of each leaf. The edges of each leaf are covered with long spines. Nectar secreted by the plant attracts flies to the leaf. When a fly touches the sensory hairs, the leaf immediately closes. Next, fluids and enzymes break down the prey and minerals are absorbed by the leaf. Since this plant is popular in the horticultural trade, it is threatened in its original habitat. Q: What helps an insectivorous plant attract and digest insects? Choices: - specialized flowers - special seeds - spines - specialized leaves A:
specialized leaves
