Gene imprinting is an epigenetic phenomenon when two alleles of a certain gene are expressed at different level depending on their parent-of-origin. Gene imprinting has been documented in mammals and flowering plants. In the 1980s, biologists’ attention to imprinting has greatly increased due to the recognition of its importance during mammalian development [1]. Imprinted genes regulate cell growth, cell signaling, cell cycle regulation, and influence nutrient acquisition and fetus growth. In mammals

Anatomy of an Orchid Flower Despite the astonishing diversity found in the thousands of wild species and man-made hybrids, orchid flowers show an unmistakable family resemblance. Orchid flowers are generally bilaterally symmetrical—only a single imaginary line can be drawn through a flower to create a mirror image. A typical orchid flower has three sepals (the outer segments that protect the bud before the flower opens), alternating with three petals. The petals and sepals may be similar or not,

Why Regulations Are Needed to Protect Pollinator Populations Currently, an estimated 3.2 million tons of pesticides are used each year (Hicks, 2012). Pesticides are normally misused by people with little knowledge or care for their harmful effects. Without effective enforcement of regulations, pesticides are easily spread beyond their projected areas. According to research, the overuse of pesticides causes many human diseases, animal diseases, and disruptions in our ecosystem. Well defined regulations

should not take it for granted. Let’s value the worth of it while it is not too late. Let’s help each other to take care of it so that we can enjoy it forever. Nature is everything which surround us and one of this is the flower. Flower is a part of a plant. It is a reproductive organ that produces eggs and pollen grains. Many flower have brightly colored petals and sweet fragrant which make them unique from the other living things. They produce nectar that attracts insect, animals and human too. While

most amazing species. This specie includes 1,795 different kinds of plants. These Begonias grows best in soils that are moist in tropical and subtropical areas under the filtered sunlight. But if these plants will be exposed in too much sunlight, it will only produce a small number of flowers. Although in cooler temperature, some of these species are being cultivated and grown inside the house to be used as decorative house plants. However, there are also times that these flowers are grown outside

includes one of my favorite appetizers, the Smashed Chickpea Avocado Dip. This recipe is the all in one Holy Grail of quick healthy snacks. As mostly any other plant-based recipe, this healthy appetizer is notorious for its use of highly nutritious fruits and vegetables, which as we know, would not exist without the help of our beloved plant companions. Moreover, this recipe, unlike any other, is quick and often fun to make. In fact, it can often serve as a

Plants are extremely important to the growth and development of Canada because as a source of food, the country requires the nutrients the plants provide and they are irreplaceable. Plants are crucial as they are a component of everything people eat, whether people eat the plants or the animal they eat or get food from rely on plants. The more food and plants available to better the reproduction, and therefore more population growth in communities. Having more food available for the entire population

involves the joining of gametes [ e.g. sperm, pollen, egg] to form a single cell called a zygote [ or fertilised egg ]. The offspring are similar, but not identical to the parents. Sexually Reproductive organisms include mammals, most reptiles, and flowering plants. ADVANTAGES There is greater genetic variation of the offspring and therefore, greater chance of survival in changing environments. Asexual Reproduction is the process by

The breeding of the red-fleshed apples was originally from Kazakhstan and improvements of the apple was breed in order for the breeders to produce a apple that has high in Vitamin and as a healthy diet snack. The scientists have collected the apple’s seeds in order to let those seeds to grow in New Zealand. The red-fleshed apples were usually small back in Kazakhstan and it has a different taste which was a bit bitter and had a lack of quality in the commercial marketing. Also they have improved

Lesson 3 Essay Questions: 1. Compare and contrast directional selection and disruptive selection and provide an example of each. Both directional and disruptive selection is a type of natural selection. Natural selection is the differential survival and/or reproduction of organisms as a function of their physical attributes. (phenotype) This results in evolution over many generations. Each mode of selection alters the mean or variance of a phenotypic trait in a population or species. These
