Biodiversity is all the different kinds of life you’ll find in one area—the variety of animals, plants, fungi, and even microorganisms like bacteria that make up our natural world. Each of these species and organisms work together in ecosystems, like an intricate web, to maintain balance and support life.

Some of the ways to protect biodiversity are:

1Conserve your water use: Fresh bodies of water are essential to biodiversity. Reducing the amount of water you use, by having a 5-minute shower or not running the water when washing up the dishes, can help protect vital wetlands.Plant scientists are also working to help conserve by developing crop varieties that use less water.

2Protect natural habitats: Human impact on the earth can have a devastating impact on biodiversity. Small steps like keeping to walking paths, and not stepping through flowers or crops, can help protect what is growing there.

3Support farmers: Farmers play a key role in conserving biodiversity.

With the help of biotechnology and plant science, farmers can grow more food on the same amount of land. This takes the pressure off the need to convert natural habitats into farmland.

4Reduce, reuse and recycle: Recycling reduces pollution by decreasing energy, electricity, and water consumption and the need for landfills. Not only can you recycle bottles and cans, but your local recycling center will usually allow you to recycle clothes, electrical goods and batteries.Programs around the world have collected and recycled almost 800,000 metric tons of empty pesticide containers and agricultural plastics in the last thirteen years. That is more than the weight of 100 Eiffel Towers.

5Plant local flowers, fruits and vegetables: Research the plants and vegetables that are local to your area and grow a variety. Each plant and vegetable helps to protect biodiversity and supports the wider ecosystem of your local area.

6Help the bees: Bees pollinate nearly 90% of plant species and they contribute to more than 35% of the world’s food supply, but they’re under threat from varroa mites. Plant scientists are developing cutting edge crop protection products to help farmers control the mites and protect precious bee populations.

)Educate yourself and others: Educating people about the importance of biodiversity conservation increases public awareness of the issue. As public awareness increases, people become more involved in caring about their environment.

With no anterior-posterior body axis, the infant would most likely grow into type D, according to the statement.

Bicoid protein promotes the expression of anterior gap genes such hunchback, orthodenticle, & buttonhead while suppressing the translation of downstream mRNA.

This embryo lacks workable bicoid mRNA and has bicoid mRNA pumped at the posterior end. Because it lacks fully functioning bicoid mRNA, the anterior end cannot develop, while the posterior end these have bicoid mRNA injected, the posterior tail won't develop, resulting in the absence of an anterior-posterior body axis. Normally, bicoid casein prevents the development of the posterior end and inhibits the establishment of the tail in.

Drug seeking and usage that is obsessive, or difficult to control, despite negative effects, characterizes addiction as a chronic condition.

Most people choose to use drugs voluntarily at first, but continued drug use can result in brain changes that make it difficult for an addict to maintain self-control and interfere with their capacity to withstand strong desires to use drugs. Drug addiction is seen as a "relapsing" disease because of these potentially long-lasting brain changes; those in recovery from drug use disorders are more likely to relapse even after years of abstinence.

The brain adjusts as a person uses drugs by lowering the ability of cells in the reward circuit to react to it. As a result, the person experiences a lower high than they did when they initially started using the drug. This is a phenomenon known as tolerance. To try to get the same high, they can use more of the substance.
