d. Trisomy

Answers

C. Nondisjunction.
Nondisjunction is the failure of one or more pairs of homologous chromosomes or sister chromatids to separate normally during nuclear division. This can result in deformities in a new-born such as Down Syndrome, due to lack of chromosomes in the body.

A. The population increases next to a shoreline.
B. Sand along a shoreline is repeatedly picked up by waves.
C. Sediment is deposited by a river.
D. Running water cuts small channels into a slope.

Answers

The correct answer is D. Running water cuts small channels into a slope. That's because the running water's force is stronger than the resistance of the land. This causes erosion to occur and the water to carry the material from the land with it, creating a little channel that is usually not that deep but it can go to great lengths.

Which pairings match protozoa with the structures they use to move? amoeba: flagellum; euglena: cilia; paramecium: pseudopod amoeba: pseudopod; euglena: flagellum; paramecium: cilia amoeba: flagellum; euglena: pseudopod; paramecium: cilia amoeba: pseudopod; euglena: cilia; paramecium: flagellum

Answers

Answer:

The correct answer is - amoeba: pseudopod; euglena: flagellum; paramecium: cilia

Explanation:

Protists use different type of structures for their movement known as pseudopods, flagella, and cillia.

Pseudopods are the structures found in amoeba in which flowing of protoplasm moves the amoeba forward.

A euglena moves by strikes or whip its flagellum, that is a long appendages, like propeller of a helicopter.

Cilia are thin, very small tail-like structure that stretched outward from the of body of paramecium.

Thus, the correct answer is - amoeba: pseudopod; euglena: flagellum; paramecium: cilia

The Siberian Husky is a medium dog, weighing between 16-27kg (35-60lbs). These dogs have strong pectoral and leg muscles, allowing them to move through dense snow. If they had heavier muscles, they would sink deeper into the snow and move slower. Yet, if they had lighter muscles, they would not be strong enough to pull sleds and equipment. This is an example of which type of natural selection? A)Directional selection B)Stabilizing selection C)Disruptive selection

Answers

Your answer is B.
Directional selection is not right, because this has nothing to do with direction.
Disruptive is not correct, because the dog keeps on moving, not stop because of its weight.

what energy conversion took place on a strawberry bush to make the suns energy turn into carbohydrates

Answers

The strawberry bush has green leaves in which photosynthesis can occur. During photosynthesis, sunlight energy is converted into chemical energy stored in carbohydrates. Photosynthesis occurs in the leaves of green plants. During photosynthesis, carbon dioxide and water are converted into glucose and oxygen using the energy of sunlight. The excess of glucose synthesized in photosynthesis is converted and stored as a starch. Thus, one energy (sun energy) is converted into another (chemical energy) in the process of photosynthesis.
