Answer the following question given this paragraph: Testes The testes (singular = testis) are the male gonadsthat is, the male reproductive organs. They produce both sperm and androgens, such as testosterone, and are active throughout the reproductive lifespan of the male. Paired ovals, the testes are each approximately 4 to 5 cm in length and are housed within the scrotum (see Figure 27.3). They are surrounded by two distinct layers of protective connective tissue (Figure 27.4). The outer tunica vaginalis is a serous membrane that has both a parietal and a thin visceral layer. Beneath the tunica vaginalis is the tunica albuginea, a tough, white, dense connective tissue layer covering the testis itself. Not only does the tunica albuginea cover the outside of the testis, it also invaginates to form septa that divide the testis into 300 to 400 structures called lobules. Within the lobules, sperm develop in structures called seminiferous tubules. During the seventh month of the developmental period of a male fetus, each testis moves through the abdominal musculature to descend into the scrotal cavity. This is called the "descent of the testis. " Cryptorchidism is the clinical term used when one or both of the testes fail to descend into the scrotum prior to birth. Q: What is the name for the male reproductive organs or gonads? Choices: - nucleus - anus - ovaries - testes A:
testes

Q: Answer the following question given this paragraph: To research how characteristics are passed from parents to offspring, Mendel needed to control pollination. Pollination is the fertilization step in the sexual reproduction of plants. Pollen consists of tiny grains that are the male gametes of plants. They are produced by a male flower part called the anther (see Figure below ). Pollination occurs when pollen is transferred from the anther to the stigma of the same or another flower. The stigma is a female part of a flower. It passes the pollen grains to female gametes in the ovary. Q: What is the fertilization step in the sexual reproduction of plants? Choices: - hibernation - Fornications - evolution - pollination A:
A: pollination
Question: Answer the following question given this paragraph: temperature: A measure of the average kinetic energy of the particles in matter. In everyday usage, temperature is how hot or cold an object is. Q: What is the common measure of how hot or cold something is? Choices: - variation - precipitation - weight - temperature A:
Answer: temperature

Answer the following question given this paragraph: Plants are the primary producers in terrestrial biomes. They make food for themselves and other organisms by photosynthesis. The major plants in a given biome, in turn, help determine the types of animals and other organisms that can live there. Q: What are the primary producers in terrestrial biomes? Choices: - soil - gases - animals - plants A:
**Answer**
plants
