Answer:
Alzheimer's disease
Explanation:
Alzheimer's disease occurs when there is a presence of abnormally structured neurons and a reduced amount of acetylcholine in the regions of the brain involved in reason and memory. These neurons have fibrous proteins present in the form of bundles around the nucleus and amyloid plaques. Malfunctioning of these regions of the brain results in a gradual loss of reason with memory lapses. It makes the person unable to perform any type of daily activity. The given symptoms represent the fact that she is suffering from Alzheimer's disease
Answer:
The bacterial DNA gets degraded at step 3 of the viral lytic cycle.
Explanation:
Viruses are organisms that are incapable of replicating on their own, hence, they require a living host which they infect and use its replicational ability to reproduce theirselves. The infection cycle of this virus is regarded as its replication cycle. Viruses employ either the LYTIC or LYSOGENIC cycle for infection.
The lytic cycle involves killing of their host cell at the end of the cycle. Generally, the cycle starts with the attachment of my the virus to the cell membrane of its host using specific receptor sites (step 1). It then penetrates the host cell as seen in step 2.
After penetration, the virus then secretes certain degrading enzymes called ENDONUCLEASES that degrades the bacterial DNA. After which the virus uses the replicational and gene expressing ability of the host to transcibe its genetic material and replicate itself. This process called SYNTHESIS occurs in step 3.
Hence, the yellow ring in the image that represents bacterial DNA disappears in step 3 (synthesis stage) because it gets degraded by viral digesting enzymes.
Answer:
The rock pocket mice rely on their fur color for camouflage. So, on the tan sand more light colored mice will survive because they blend in and on the dark lava rock more dark colored mice will survive and the allele for dark fur will be passed on to their offspring
Answer:
A glucose molecule is smaller
Explanation:
An artificial membrane has pores of a specific size.
Molecules that are small enough can pass through the pores, but others may be too big.
Glucose (C₆H₁₂O₆) has a certain size, but a sucrose molecule (C₁₂H₂₂O₁₁) is bigger.
If the membrane pores are just the right size, a glucose molecule will be able to pass through, but a sucrose molecule won't.
The region of the body that will be examined is the EPIGASTRIC REGION.
The epigastric region refers to the upper central region of the abdomen. Its exact location is in-between the coastal margin and the sub - coastal plane.
