Biology

Not sure what the options are, but artificial selection would be when farmers/breeders choose only to plant/breed the organism with desired characteristics in order to cause the evolution of the trait while natural selection is when organisms that are better adapted to their environment usually survive and produce offspring, causing the evolution of their traits which help them to survive.

Hope that helps!

HELP 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.

Give pollinators an extra boost in your backyard by planting a variety of wildflowers and native plants to provide nectar that will bloom throughout the season. You can also build bee boxes for native bees to make their home.[1]

PLANT LOCAL FLOWERS, FRUIT 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.

PROTECT 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.

TAKE A WALK
Climate change can have devastating consequences for biodiversity. Reducing your carbon footprint by taking the bus or walking can help protect it.

Plant scientists are also working to combat climate change every day. One example is through innovative developments in conservation tillage, which uses less fuel and therefore reduces the emission of greenhouse gases.

CONSERVE 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.

REDUCE, REUSE AND RECYCLE
Recycling lessens 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.

SUPPORT 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.

BUY LOCAL FOODS WHEN YOU CAN
Buying from your local farmer at a farmers’ market or through a farm stand gives you the ability to find out how your food was grown and learn what they are doing on the farm to help conserve biodiversity.

VISIT YOUR LOCAL BOTANICAL GARDEN
Botanical gardens are great for biodiversity conservation, as scientists can store, study and grow plants in their native habitats. Visiting and donating to your local botanical garden will help them continue to protect and promote biodiversity.

EDUCATE YOURSELF AND THOSE AROUND YOU
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.

saw5 [17]

Answer;

-Midsagittal cut

A neuroscientist cuts a brain in half, along the division between the hemispheres. this cut is referred to as a midsagittal cut.

Explanation;

The midsagittal plane divides the human body into equal left and right halves. It is used to describe the sagittal plane as it bisects the body vertically through the midline marked by the navel, dividing the body exactly in left and right side.

-If divided along this plane, the deepest structures of the human body will be visible. Starting with the most superior portion of the body, visible would be the brain. Cutting along the midsagittal plane, the structures of the brain would be exposed including the pineal body, the corpus callosum, thalamus, midbarin, pons, medulla oblangata, hypothalamus, and the arbor vitae of the cerebellum.

xxTIMURxx [149]

Answer:

The correct answer would be non-disjunction.

Down syndrome refers to the genetic disease caused by the non-disjunction of chromosome number 21.

Non-disjunction refers to the event in which the homologous chromosomes or sister chromatids fail to separate properly during a cell division.

In Down syndrome, the sister chromatids of chromosome 21 fail to separate properly which results in the formation of a gamete with 2 copies of chromosome 21.

When this gamete fertilizes with another gamete, it results in the formation of a zygote with 47 chromosomes, that is, 46 chromosomes + extra copy of chromosome 21.
