Correct Answer: C)

Explanation

In this question, we are asked to determine the probability of producing a heterozygote progeny in a cross between two heterozygote individuals of pea plant. To understand this, we need to first understand the concept of heterozygotes and the Punnett square. Heterozygote individuals have two different alleles for a specific trait (e.g., Tt, where T represents the dominant trait and t represents the recessive trait). In pea plants, let's assume that the tall trait (T) is dominant over the short trait (t). So, a heterozygote pea plant would have a genotype of Tt. To find the probability of producing a heterozygote offspring, we can use the Punnett square. The Punnett square is a tool that helps us visualize the possible combinations of alleles in the offspring. In this case, we are crossing two heterozygote pea plants (Tt x Tt). The Punnett square for this cross would look like this: T t T TT Tt t Tt tt From the Punnett square, we can see that there are four possible genotypes for the offspring: TT (homozygous dominant), Tt (heterozygous), tT (also heterozygous), and tt (homozygous recessive). The probability of producing a heterozygote offspring (Tt or tT) is 2 out of the 4 possible outcomes, which simplifies to: 2/4=

Correct Answer: D. tuberculosis

Correct Answer: A) starch

Explanation

Mucor and Rhizopus are types of fungi that absorb carbohydrates in a specific form. The question is asking which form of carbohydrate is absorbed by these fungi. The options given are starch, sucrose, glycogen, arabinose, and glucose. Out of these options, the correct answer is starch. This means that when Mucor or Rhizopus fungi absorb carbohydrates, they do so in the form of starch. Starch is a complex carbohydrate that is made up of many glucose molecules linked together. When starch is broken down by enzymes in the fungi, it is converted into glucose which the fungi can then use for energy. Sucrose, glycogen, arabinose, and glucose are also forms of carbohydrates, but they are not the form that is specifically absorbed by Mucor and Rhizopus. Sucrose is a disaccharide made up of glucose and fructose, while glycogen is a storage form of glucose in animals. Arabinose is a type of sugar found in plants, and glucose is a simple sugar that is a main source of energy for many organisms. In summary, the correct answer to the question is starch, which is the form of carbohydrate absorbed by Mucor and Rhizopus fungi. For more information, please see the recommended textbooks.

Correct Answer: B. insulin

Correct Answer: C) scavengers and predators

Explanation

Hyenas are animals that can feed on the remains of other animals that have been killed by other animals or they can also kill animals for food. This means that they can be described as animals that scavenge, which means they feed on dead animals, and as predators, which means they hunt and kill other animals for food. Therefore, the correct answer to this question is option C, which describes hyenas as scavengers and predators. It is important to note that scavengers play an important role in the ecosystem as they help to clean up dead animals and recycle nutrients back into the environment. Predators, on the other hand, are also important as they help to control populations of other animals and maintain a balance in the ecosystem. In contrast, herbivores are animals that feed on plants, while parasites are organisms that live on or in another organism and feed off of it, often causing harm to the host. Therefore, options A and D, which describe hyenas as herbivores, are incorrect. Option B, which describes hyenas as scavengers and parasites, is also incorrect as hyenas are not parasites. Option E, which describes hyenas as herbivores and parasites, is also incorrect.
