What determines how strong an earthquake is?

Answer AND Explanation:

The cardiac muscles form the wall of the heart. The fibres are made up of many cells, which are joined end to end through intercalated discs. They have more mitochondria than skeletal and smooth muscles. Cardiac muscle is myogenic meaning that the rhythmical contraction originates from within.

Vitamins. A lot of coenzymes are derivatives os vitamins especially B vitamins.

Answer:

Acid desposition is very harmful for the environment because it can easily combine with primary pollutants like carbon monoxide, particulate matter, sulfur oxide etc and form harmful substances.

Explanation:

• Acid desposition means acid forming pollutants in the atmosphere that can easily combines with the primary pollutants which is emitted from car and energy power plants.

• One of the major culprit is sulful dioxide which is released from car. Once they react with water, produce sulfuric acid and nitric acid. Their pH is extremely low thus they acts as acid.

• These acidic desposition create hazards in aquatic body,wetlands,aquatic fishes,shell fishes,may cause nitrogen pollution and also cause damage in ecosystem.

• This is the main reason that acidic desposition often felt in area far from pollutants so that it does't hamper the ecosystem.

Answer:

1. They provide home and shelter for millions of species of marine organisms.

2. They play a role as nutrient recyclers and in carbon and nitrogen fixation.

3. They are vital in the marine food chain as they are the main source of essential nutrients.

Explanation:

Cnidarians are extremely ecologically important organisms that play a significant role in the animal kingdom and nature.

For instance, coral reefs, which are built by hundreds to thousands of cnidarians, provide home and shelter for millions of species of marine organisms, from small crustaceans to large fish such as sharks. Furthermore, they play a role as nutrient recyclers and in carbon and nitrogen fixation. In addition, they are vital in the marine food chain as they are the main source of essential nutrients such as nitrogen.

Today, these organisms are threatened due to human activities and anthropogenic climate change, so it is fundamental to develop better strategies to protect and restore them.

Answer:

Developmental progression of functional skills

Explanation:

With the passage of time, a kid not only grows physically and mentally but also in his/ her cognitive abilities to perceive and understand the happening around him. He develops a a relationship sense for peers, family members and related adults. Similarly, he also develops the ability to learn the things which are quite basic for us like taking off clothing items.

These things come under the umbrella of developmental progression for functional skills.  studies have shown that a kid learns to take off clothing items before he learns to  put them on. Same is the case with putting on socks, a kid can take off socks by the age of 12 months which is earlier than he learns to put them off (age of 18 months) with the assistance of any elder and independently by the age of almost 4 years.

This developmental progression helps a kid to modify his behavior and to be more independent.
