How can mutations be helpful? Give 2 examples

1 answer:

6 0

Having two copies of the mutated genes cause sickle cell anemia, but having just one copy does not, and can actually protect against malaria - an example of how mutations are sometimes beneficial.

The majority of mutations have neither negative nor positive effects on the organism in which they occur. These mutations are called neutral mutations. Examples include silent point mutations. They are neutral because they do not change the amino acids in the proteins they encode.

Hope this helped :)

$\bold{ \green {Scope \: of \: Environment \: education}}$

Environmental education includes the study of various factors of the environment which affect the health of human beings. Environment comprises all the factors in our surroundings. It includes even abstract factors , which do not have weight , length and breadth. Cultural traits , social norms and values, feasts and festivals etc. are some of the examples of abstract aspects. Some of the scopes of environment education are described below:

Physical aspect ( soil , water , air , rocks , gases etc )

The physical aspect included non- living things on the earth. They are soil, water , air , rocks , gases etc. Environment education gives knowledge about the status of soil , water , air , rocks , gases and other various physical components of the earth. It aims to make students aware of the effects and consequences of human activities upon these factors. It also gives knowledge to raise environment friendly attitude and behavior among the students .

Biological aspect ( biology , agriculture , forestry etc )

The biotics factors include living plants and animals , their life mechanism , interrelationship etc. Some of the educational streams related to the biotic aspects are biology , agriculture , and forestry. They are some of the important scopes of the environment education. This branch of education helps to develop the level of knowledge , attitude and behavior regarding these factors in the students.

Socio - cultural aspect ( sociology , civics , religion , ethnicity , anthropology etc )

Environment has some of the abstract aspects too. Abstract aspects include religious , cultural , ethnic and social norms and values. Some of the educational streams dealing with this aspect are sociology , civics and anthropology. Environment education also teaches students about such abstract factors, which play vital role in the environment.

$\bold{ \green{Scope \: of \: Health \: education}}$

In general , scope of health education can be understood as the areas included in health education. Health education not only communicates knowledge about body features and diseases, but also includes the matters concerned with healthy surroundings , human psychological states affecting health , public health, human anthropology , medical science and so many other things. Any three scopes of health education are as follows:

Home

Home is the residence of all people. Home is the first school for all. A child passes the primary days of life at home. Every individual learns the basic skills if survival at home. Proper time to wake up in the morning , to start daily sanitary schedules, to eat , to practise all other health behavior are learnt at home. The child lives in community and learns many more about healthy social adjustment in the social environment. Health education aims to raise the level of knowledge , attitude , and behavior related to health and healthy life.

School

Children go to school for formal education and spend most of active hours of a day. They achieve several forms of health knowledge and develop healthy attitude and practise accordingly. Their heath status depends upon the environment of school , health curriculum, healthful school environment , co-curricular and extra - curricular health activities.

Community

Community is a place where many people live with their families. People's health is determined by the several factors in the community. Health education teaches about these factors like community sanitation , drainage , health service providing organizations and health centers.

I'll give 100 points & a brainliest for whom ever can answer these properly. This is for a grade 11 semester research paper

I kept a record of the sources with the extracted information. I have the links if you would like them.

Hydro-international article: Benthos, Inc.

Benthos was founded by Samuel O. Raymond.

He created an innovative company in marine technology which has positively impacted the field for over four decades.

It manufactures a variety of oceanographic equipment, including flotation devices; hydrophones for locating mining sites, tracking boats, and research for marine biology; and modems, which are used to communicate information wirelessly underwater.

For much of the company's lifetime, it supplied underwater equipment to the military, the government, and for research.

Smithsonian Magazine: 14 fun facts about marine bristle worms

Polychaete worms are a diverse class of animals with at least 10,000 species.

They are characterized by a head and a tail, and a pair of bristled "legs", called parapodia, for each segment of their body. They are typically bioluminescent, meaning they have the natural ability to glow.

Due to their effective adaptation, they can live in any marine habitat (including coral reefs, hydrothermal vents, or simply out in the open ocean) and have survived the five mass extinctions since 500 million years ago.

National Ocean Service: What is a bivalve mollusk?

Bivalves are mollusks with a two-part hinged shell to cover a soft invertebrate. They breathe and eat using gills.

Their organ, the mantle, produces calcium carbonate which causes the shell to grow with the organism.

They have important roles of being prey for predators, filtering water, and acting as a habitat in aquatic ecosystems.

These mollusks can live in any of the five oceans, whether it be the frozen Arctic or the hydrothermal vents in the Pacific.

There are over 9000 species.

Marine Education Society of Australasia: Echinoderms

Echinoderms are characterized by radial symmetry, having multiple of five arms, a calcium carbonate shell, and an outer layer of skin that maintains the skeleton.

They are found on the sea floor and include starfish, sea cucumbers and sea urchins.

They have the ability to hunt prey larger than their mouths due to their ability to eat from their stomachs. They detect food through a senstitivty to chemicals, although they lack any brains.

There are over 7000 species.

Thoughtco: Sea Squirts

Sea Squirts, scientifically tunicates or ascidans, are a class in the animal kingdom with over 2000 species.

They were given this name for their ability to contract and squirt water.

They do this using the inhalant and exhalant siphons, which are also used for eating and excreting waste.

They live in subtidal locations while attached to shells, rocks, piers and boat hulls.

Sea Squirts may live in colonies or individually. Colonies are created when they reproduce by budding, or when a new animal grows off of the original.

National Geographic.com: Sea Anemones

Sea anemones are an invertebrate which have stinging and venom-filled tentacles, called polyps, to hunt passing fish.

They tentacles surround a central mouth and inject a paralyzing substance into its prey, before guiding them into the mouth.

Apart from hunting, they also eat leftovers from clownfish, who are immune to the anemone because they are covered with a mucus and live within the polyps.

They live attached to rocks on the seafloor and coral reefs, usually in tropical waters.

There are over 1000 species.

Conclusions or Summary:

The marine technology company Benthos led to the discovery or further information about these animals because it provided equipment to researchers.

All of these organisms are animals and diverse with thousands of species in each of these common names.

They are adaptive and can generally live and thrive in a variety of habitats, whether the difference be in surface material or climate.
