None of the above

Answers

Answer:

The correct answer will be diatoms.

Explanation:

Diatoms are photosynthesizing micro-algae found in both marine and freshwater usually hard and rough in appearance due to deposition of silica in their cell walls.

They live in both photic and planktic region of the ocean and in both unicellular to colonial forms and form the major part of the planktons.

Their large number of species counts for about 20,000 and new species being discovered every year and their reproduction through simple cell division makes the most numerous unicellular algae in the oceans

Thus, diatoms is the correct answer.

Linda has a cup of coffee sitting in the cup holder in her car. She has to suddenly slam on her brakes and stop. The cup remained in the cup holder, but the coffee splashed and spilled everywhere. Newton's _____ law can best describe why this happened.

Answers

Newton's First law can best describe the situation that has been given in the question. Newton's First law states that a body will remain in motion or in a static state unless acted upon by a opposite force. In this case the car driven by Linda was travelling in one direction until Linda slammed the brakes and the opposite force started acting on the car. The coffee cup also stopped, but the coffee moved in the direction the car was moving.

Answer:

The Newton's first law of motion will be applied in this situation.


Explanation:

As mention in the question, the car was moving then every object inside the car was also in the motion state with the same velocity as the car had. when the brake applied on the car, the brake only stopped the motion of the car than the objects inside it. According to the first law of motion, due to inertia, the body keeps its state intact until an external force applies to change its state. Because of inertia, the coffee inside the cup was in moving state with the car. When brake applied the coffee spilled out of the car to maintain its state and spread all around. If the cup would keep out of the cup holder, It will move also forward on the applied brake.

Label each example as either (PI) passive or (AI) active immunity:a. ________ Bill had chicken pox when he was five. He doesn’t catch it again, even when his nephew gets sick with the virus.
b. _______ Billy Jr gets vaccinated with a live attenuated form of the chicken pox virus. He doesn’t get chicken pox after playing with his infected cousin.
c. _______ Bill’s 3 month old daughter is breast feeding. She does not get chicken pox after playing with her infected cousin.

Answers

First, let's distinguish active from passive immunity:
- Active immunity occurs in a direct exposure of individuals to live pathogens. The result is a development of a disease. After that, individuals acquire immunity to the disease.
- Passive immunity is induced by vaccines with antibodies for a disease, so the disease does not develop.

a. ACTIVE IMMUNITY - Bill had a disease, so it must be active immunity.
b. PASSIVE IMMUNITY - Bill got a vaccine and a disease did not develop, so it must be passive immunity.
c. PASSIVE IMMUNITY - Although, 3-month-old daughter did not get a vaccine, she has mother's antibodies from the milk so she will not develop a disease.

Answer:

Active

Active

Passive
