Our understanding of DNA and gene expression has dramatically increased over the last 50 years. Describe 2 positive impacts and
lozanna [386]

Positive impacts of genetic engineering:

• New products are created such as food with higher nutrition values, drugs that are more effective and safer

• Disease prevention (“correcting” the genetic mutation, or removing disease-causing gene)

Negative impacts of genetic engineering:

• irreversible side effects, for example resistance of bacteria or introduction of viruses in human cells

• abusing like change specific traits that are not connected with diseases, create human outcomes that are ethically questionable.

What happen if interference in blood flow occur??
ivann1987 [24]
Think of a stroke as a "brain attack"— it is an emergency! When symptoms appear call 911 immediately; every minute counts. A stroke occurs when the brain is deprived of blood supply. Without oxygen brain cells die. Depending on the area affected, a person may have problems speaking, walking, seeing, or thinking. It may result in permanent brain damage, disability or death. If the stroke is caused by a blood clot, a clot-busting drug may be given to restore blood supply.To understand stroke, it is helpful to understand the circulatory system of the brain (see Anatomy of the Brain). Blood is carried to the brain by two paired arteries, the internal carotid arteries and the vertebral arteries (Fig. 1). The internal carotid arteries supply the anterior (front) areas and the vertebral arteries supply the posterior (back) areas of the brain. After passing through the skull, the right and left vertebral arteries join together to form a single basilar artery.

The basilar artery and the internal carotid arteries “communicate” with each other in a ring at the base of the brain called the Circle of Willis by the anterior communicating (Acom) and posterior communicating (Pcom) arteries. The middle cerebral artery is the artery most often occluded in stroke.

PLEASE HELP!
mel-nik [20]

Answer:

Although elephants and hyraxes at first don't seem to have many similarities, a closer look has led many scientists to believe that these animals are evolutionarily closely related.

Elephants and Hyraxes share many reproductive characteristics that indicate a common ancestor: The location of the testicules in these animals diverges from most mammalian species, remaining inside the retroperitoneal abdomen. Females have similar placental origins and long gestation periods and the location of the mammary glands in both orders (above the front legs) is a unique feature among non-primate mammals. Hyraxes' tusks develop from incisor teeth, similar to elephants, and in both cases nails develop into flattened, hoof-like structures.

Molecular evidence has also been used to confirm the hypothesis of evolutionary relatedness between the two orders, as similarities in some gene sequences in mitochondrial DNA and other molecular components. Both animals have some physiological similarities and cognitive characteristics (such as the presence of a powerful long-term memory) that support the possibility of evolutionary proximity.

The fossil record indicates that in the Eocene period hyraxes were dominant herbivores in Africa, with several species, reaching much larger sizes than today and occupying different ecological niches, indicating that elephants and hyraxes may have been very similar millions of years ago.
