Answer: Sperm Whale

Explanation:

They found that the DNA sequence of the sperm whale and pygmy sperm whale were more closely related to the baleen whales than to other toothed whales and dolphins. The study also showed that the beaked whale (which has only a few teeth) is only distantly related to any other whale or dolphin. Stated in science article by Koen De Smet. Not plagarized. Hope this will help you understand.

Answer:

The cell will shrink and wrinkle

Explanation:

Hypertonic solutions have more solute than solvent. The external solution will have a higher osmotic pressure than the cell contents and therefore water will pass out of the cell which will then shrink.

wariber [46]

Answer:

The process of natural selection is acting on Field mouse individuals where as evolution is occurring on Field Mouse population.

Explanation:

As the problem shows, the field mice are the ones that natural selection is acting on, but only the ligher shade ones. Because the lighter shade individuals are more likely to survive in the beach because they blend with the environment.

Evolution occurred on the field mouse population because if you read the script in the end, they were able to successfully reproduce. This means that they evolved in such a way that they were able to survive in their new environment. (most likely carrying on the trait of light-colored fur)

Natural selection acts on traits, phenotypic traits, favorable to the environment. Evolution occurred because of the natural selection, because the favored trait enabled the organism to adapt to the environment.

What are the three examples to justify Newton first law of motion .

Sergeu [11.5K]

Explanation:

1.Law of Inertia

Inertia : is the ability to resist change in motion.

Example; if you roll a ball it will keep running unless you change it's direction with the help of friction..

2. second law of motion states that an object will accelerate when an unbalanced force is applied on a mass..

unbalanced force is a type of force where total force≠zero, means the object will move..

Example; if you will try to push a truck will be less but if you push a car the acceleration will be more.. because car has less mass..

3. the third law of motion state that foreign every action there is a opposite reaction..

Example; can you throw a ball on the floor ...the floor pushes back that the ball..

1. Why does the Elodea cell have chloroplasts but the onion cell does not, even though both are plant cells? Please answer quick

Oksanka [162]

Chloroplasts contain chlorophyll which is what makes plants green. Onions are not green because they do not contain chloroplasts. The reason they do not have chloroplasts is because in the chloroplast, photosynthesis takes place. A key player in the process of photosynthesis is the sun. The onion itself grows underground which means while they grow they do not come into contact with the sun so chloroplasts in an onion is pointless since they can’t undergo photosynthesis. Hope I helped!
