What allows nongovernmental organizations to play a major role in environmental issues?

2 answers:

6 0

The non governmental organizations plays an important role in environmental issues by their way of raising awareness in the contribution of helping the environment. With this, they could undergo an independent task that will suffice and benefit not only the people but the environment itself.

NGOs or non-government organizations are organizations which are building by citizens and are free from governmental influence.

These organizations are non-profit means they work for the betterment of people with nothing in return.

Their nature of being independent and run by funds and donations allows them to work for and play a role in environmental issues.

As I mentioned earlier, these organizations work for the people and their betterment which is another factor that gives them this right.

katrin [286]

Answer:

Explanation:

Horses:

Common characteristics with primates:

- Hair: Most mammals have hair with different functions, depending on the animal and the body area they are covering. Horses hair provides insulation, thermal regulation, protects the skin against elements such as wind, sun, rain; serves as camouflage, assists in sensory perception and transport of pheromones. It also protects against insects and serves as a barrier to chemical, physical and microbial invasion to the skin. Hair can take on several different forms depending on their function. Horses have three different kinds of hair: permanent hair, temporary hair that covers most of the body, and the tactile hair on the muzzle and the ears.

- External ears: As primates, horses have external ears that direct external sounds from the environment to the tympanic membrane. The auricle is the visible portion of the outer ear and can be a strong indicator of the mood of the horse. It is created by cartilage, a thin covering of skin and muscles attaching to the base.

Primate traits that they lack:

- Fingers and toes: Horses do not have fingers and toes as the other mammals. Instead, they have one toe. The pedal bone, which is a hoof-shaped structure in feet, serves for the attachment of tendons and ligaments from the muscles in the forearm. This is the biggest and most important hoof bone.

- Short Nose: Primates suffered a progressive reduction in nose size over time. They have small noses compared to horses, whose sense of smell is much better due to their bigger nose.

Dolphins:

Common traits:

- Mammary glands: These glands consist of ducts and glandular tissues that secrete milk, which provides young with the nourishment that they need to grow, like proteins, sugars, fats, vitamins, and salts.

- Anterior limbs: Dolphins anterior limbs are the flippers. They share the exact same bones with primates, but with shape and size modifications, depending on the species. They have five phalanges, carpals, ulna, and radius and short humerus bones.

Primate traits that they lack:

- Nipples: As all mammals, dolphins have mammal glands that secrete milk, providing young with everything they need to grow. Unlike all mammals, dolphins do not have nipples; instead, they have a slit on each side of genitals where the mammary glands are located. Whenever the baby hits the slit, it stimulates the gland and produces the milk ejection.

- Heterodoncy: As dolphins do not chew their food they haven´t developed heterodont dentition. They have homodont dentition, as they just use their teeth for caching their prey or competition between mails.

I need help with modeling a carbon cycle, do you mind helping me? :)

madam [21]

Explanation:

The Carbon Cycle

The element carbon is a part of seawater, the atmosphere, rocks such as limestone and coal, soils, as well as all living things. On our dynamic planet, carbon is able to move from one of these realms to another as a part of the carbon cycle.

Carbon moves from the atmosphere to plants. In the atmosphere, carbon is attached to oxygen in a gas called carbon dioxide (CO2). Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth.

Carbon moves from plants to animals. Through food chains, the carbon that is in plants moves to the animals that eat them. Animals that eat other animals get the carbon from their food too.

Carbon moves from plants and animals to soils. When plants and animals die, their bodies, wood and leaves decays bringing the carbon into the ground. Some is buried and will become fossil fuels in millions and millions of years.

Carbon moves from living things to the atmosphere. Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere. Animals and plants need to get rid of carbon dioxide gas through a process called respiration.

Carbon moves from fossil fuels to the atmosphere when fuels are burned. When humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas. Each year, five and a half billion tons of carbon is released by burning fossil fuels. Of this massive amount, 3.3 billion tons stays in the atmosphere. Most of the remainder becomes dissolved in seawater.

Carbon moves from the atmosphere to the oceans. The oceans, and other bodies of water, absorb some carbon from the atmosphere. The carbon is dissolved into the water.

Carbon dioxide is a greenhouse gas and traps heat in the atmosphere. Without it and other greenhouse gases, Earth would be a frozen world. But since the start of the Industrial Revolution about 150 years ago humans have burned so much fuel and released so much carbon dioxide into the air that global climate has risen over one degree Fahrenheit. The atmosphere has not held this much carbon for at least 420,000 years according to data from ice cores. The recent increase in amounts of greenhouse gases such as carbon dioxide is having a significant impact on the warming of our planet.

Carbon moves through our planet over longer time scales as well. For example, over millions of years weathering of rocks on land can add carbon to surface water which eventually runs off to the ocean. Over long time scales, carbon is removed from seawater when the shells and bones of marine animals and plankton collect on the sea floor. These shells and bones are made of limestone, which contains carbon. When they are deposited on the sea floor, carbon is stored from the rest of the carbon cycle for some amount of time. The amount of limestone deposited in the ocean depends somewhat on the amount of warm, tropical, shallow oceans on the planet because this is where prolific limestone-producing organisms such as corals live. The carbon can be released back to the atmosphere if the limestone melts or is metamorphosed in a subduction zone.

GREYUIT [131]

The sugar and phosphate bond is placed outward of the DNA towards the solvent and the base of nitrogen is inside the helix.

Explanation:

The edges that are outward to the double helix formation of DNA are composed by sugar and phosphate molecules and make the backbone.

These two strands of DNA is placed in the opposite direction from the helix. But the nitrogen base is there inside the helix. It shapes like a ladder rung because of the hydrogen bond. This bond keeps the backbone held together.

How would Earth be different without the greenhouse effect?

madam [21]

B more ice on the earths surface. Greenhouse gases don’t tend to block the solar energy, but trap the energy that radiates from the earths surface. Dissolved CO2 becomes carbonic acid. More CO2 results in more carbonic acid. Methane is one of the greenhouse gases.

2. What is formed when elements of matter are chemically combined?

Lelu [443]

Answer:

Option B. compounds

Explanation:

Compound is a type pure substance which is formed when two or more than two elements combine together chemically in a fixed ratio. It is represented by a chemical formula. Chemically combine means the elements present in the compound make bonds in order to hold each other. So they are not separated by physical methods. It is separated from one another by chemical methods.
