1. Darwin’s theory of natural selection directly applies to the domestication of plants and animals in numerous ways. The first being that natural selection, or the differential survival and reproduction of individuals due to differences in phenotype is based on the idea that organisms pass genetic mutations onto their offspring that can potentially increase the success of reproduction and survival for future generations. Over time these continual genetic mutations can result in a new species…

Within the anther are microsporangium that contain many diploid microsporocytes. The microsporocytes will meiotically divide into haploid microspores that will flourish into pollen grains. The generative cell will divide into two sperms and the tube cell will produce the pollen tube. Either by wind or a pollinator, pollen grains are carried to the sticky stigma of the ovary and sperm burrow their way down to the ovules. One sperm will fertilize the ova, becoming the zygote, and the other will…

environment in both Mesopotamia and Egypt, have similar characteristics. Egypt has evidence of pollen which shows that it’s climate has changed drastically over the past 14,000 years. A team of scientists believe that the pollen in the Middle East explains the sudden collapse of large groups such as Egyptians and Mesopotamians. The evidence of pollen leads them to believe that there was a long-term drought. The pollen samples also showed that there was a broad shift in vegetation in regards to…

Springtime is just around the corner and for many people that mean watery, itchy eyes, coughing, wheezing, a stuffy nose and much more.

If you want to enjoy spring without the symptoms of seasonal allergies, check out how the follow natural solutions can help fight your spring allergies. Acupuncture - Acupuncture has been shown to relieve…

spread of diseases. People do not realize that while they are trying to urbanize they tear apart sources for bees to retrieve pollen. For example, after a bee finishes almond pollination, it is important for them to feed off of higher quality protein. However, because of urbanization a lot of these resources for the bees are being torn down, so the bees lose their source of pollen and their lives. Additionally, agricultural practices today rely heavily on the use of pesticides, to kill off…

will talk about the three most interesting things in the ecosystem. I will talk about extinction, food web, and ecosystem. It will be very interesting. Bees help with a lot. They Spread pollen every where and they hurt people sometimes. Bee’s are yellow insects that can help and hurt you. They help by spreading pollen to let plants reproduce in different areas. Bee’s also help by making honey for us to eat. They are harmful because they sting us and hurt us. Bees do a lot for us humans but they…

can be given to dogs primarily for medicinal purposes. Compared to commercial honey, raw honey is unprocessed and unpasteurized. Aside from that, the Honey Bee Conservancy recommends feeding your dog raw honey that may contain small amounts of local pollen. According to the…

Bees are the world's top pollinators. There are over 20,000 different kinds of bees, and they are unfortunately dying off due to the increase of pesticides. Pollinators transfer pollen and seeds from one flower to another, fertilizing the plant so it can grow and produce food. These insects are responsible for pollinating one third of the world's crops. Bees need to live without these inorganic forms of pesticides, so that they can produce honey and pollinate crops. These healthy bees were…

food looks like for me. Will I ever be able to eat raw fruits and vegetables again? Like most people spring and I have a love hate relationship.

I never knew these outdoor allergies would affect how or what I could eat. It does make sense, if I am allergic to wild plants why wouldn’t I be allergic to fruits and vegetables, they are plants.…

This means that they deposit pollen onto flowering plants to allow fertilization, which in turn creates more plants. For humans, bees are essential because without plants, people would not have food, clothes, medicine, or oxygen to breathe. Unfortunately, humans would not be able to…
