Q: In the radiative zone, light particles called what can only travel a few millimeters before they hit another particle? Read this paragraph and choose the correct option from the provided answers: The radiative zone is the next layer out. It has a temperature of about 4 million C. Energy from the core travels through the radiative zone. The energy travels at an extremely slow rate. Light particles are called photons . In the radiative zone, photons can only travel a few millimeters before they hit another particle. The particles are absorbed and then released again. It may take 50 million years for a photon to travel all the way through the radiative zone. Choices: - electrons - positrons - neutrons - photons A:
photons

Q: Animals that have been modified to express recombinant dna are called what? Read this paragraph and choose the correct option from the provided answers: Transgenic Animals Although several recombinant proteins used in medicine are successfully produced in bacteria, some proteins require a eukaryotic animal host for proper processing. For this reason, the desired genes are cloned and expressed in animals, such as sheep, goats, chickens, and mice. Animals that have been modified to express recombinant DNA are called transgenic animals. Several human proteins are expressed in the milk of transgenic sheep and goats, and some are expressed in the eggs of chickens. Mice have been used extensively for expressing and studying the effects of recombinant genes and mutations. Choices: - reproducing animals - mammalian animals - aquatic animals - transgenic animals A:
(Answer)
transgenic animals

Ques: Q: What forms when a glacier scrapes a large hole in the ground? Read this paragraph and choose the correct option from the provided answers: The depression that allows water to collect to form a lake may come about in a variety of ways. The Great Lakes, for example, are glacial lakes. A glacial lake forms when a glacier scrapes a large hole in the ground. When the glacier melts, the water fills the hole and forms a lake. A kettle lake forms in the sediment left by a glacier when a block of ice melts. Kettle lakes are found where continental glaciers once covered the land ( Figure ' below ). Over time lakes get water from rain, streams, and groundwater coming to the surface. Choices: - crater lake - underground cavern - glacial hill - glacial lake A:
Ans: glacial lake

(A).
lyme disease

Ques:Q: What are the basic units of structure and function in living organisms? Read this paragraph and choose the correct option from the provided answers: All living things consist of one or more cells. Cells are the basic units of structure and function of living organisms. Choices: - proteins - molecules - lipids - cells A:

Ans:cells

Ques: Q: Mutations which benefit the organism in which they occur are known as? Read this paragraph and choose the correct option from the provided answers: Some mutations have a positive effect on the organism in which they occur. They are called beneficial mutations . They lead to new versions of proteins that help organisms adapt to changes in their environment. Beneficial mutations are essential for evolution to occur. They increase an organism's changes of surviving or reproducing, so they are likely to become more common over time. There are several well-known examples of beneficial mutations. Here are just two:. Choices: - extraordinary mutations - helpful mutations - healthy mutations - beneficial mutations A:
Ans:
beneficial mutations
