Answer: Too many deer in a given area results in overgrazing and the eventual loss of brush and shrubs in forested areas. Loss of undergrowth means no place for small animals and birds to shelter and nest. The result is the disappearance of many native species that no longer have access to the habitat they need.
Arthritis is a joint disorder involving joint inflammation.Pain is often localized to only the affected joint. Osteoarthritis is a wear and tear type of arthritis often affects aging population affecting joints in hands,knees and lower back. Heberden's node is an example and develops around middle age thus Wendell might have this.
The resulting mice will be induced with the changed gene either on or off. The offspring will have altered genes if both the alleles have the trait. This is a heritable change.
Explanation:
Making gene on or off is a process of gene regulation when one of the gene is methylated or histone modification to prevent access to transcription factors hence no expression of the protein. This process is called epigenetics.
The resulting progeny in mice will receive the allele of on or off the gene. Such genes with altered allele are also called as
The altered genes will be expressed in the resulting progeny of mice.
The epigenetic genes can be reverted with environmental effects in the offspring paramutable alleles. They are heritable.
Answer: C
Explanation: The two chromatids of a duplicated chromosome are held together at a region of DNA called the centromere. Centromeres are the attachment points for microtubules, which are responsible for the guiding the movement of chromosomes during mitosis and meiosis.
Landslide is a general term referring to all types of surface movement, like avalanches involving the mass movement downhill of soil, rock, or snow under the action of gravity. These can be dangerous to human life.
Mudslides are caused unusually heavy rain or sudden thaw. they consist of mostly mud and water with fragments of rock and other debris. They're capable of moving house off of their foundations and can bury a place within minutes.
