Explain how structure of the intestinal lining enhances surface area

1 answer:

5 0

The interior walls of the small intestineare tightly wrinkled into projections called circular folds that greatly increase their surface area. Microscopic examination of the mucosa reveals that the mucosal cells are organized into finger-like projections known as villi, which further increase the surface area

Dafna1 [17]

The DNA clamp/sliding clamp is the protein that is present at every replication fork and prevents DNA polymerase from dissociating but does not impede the rapid movement of the enzyme. It is a protein fold that serves as a processivity promoting factor in DNA replication.

What de-polymerizes microtubules to separate sister chromatids during anaphase?

Oxana [17]

Answer:

There are two main ideas about how chromosomes move in anaphase A. One is that motor proteins at the kinetochores use the energy of ATP hydrolysis to pull the chromosomes along the kinetochore microtubules, which depolymerize as a consequence.

Predict the potential impact of severe solar weather on Earth's communication systems.

DaniilM [7]

Severe solar weather has the potential to cripple communication systems on earth.

Solar weather occurs when solar activity increases. Sudden bursts called Coronal Mass Ejections are the main culprits of solar weather. These CME's release bursts of plasma and charged particles straight towards the Earth. Once these particles impact the upper atmosphere they cause geomagnetic storms that interfere with radio signals and communication and possibly fry electronic devices.

Severe geomagnetic storms can cause devastation for Earth's communication network. These storms interfere with radio communication, meaning that phone service, radio broadcasts, and even internet connection would be disabled. Even worse, these storms can often damage electronics, specifically satellites. Damage to satellites can cause severe damage to modern-day infrastructure.

What is a karyotype? a. a system of classifying cell nuclei b. a unique combination of chromosomes found in a gamete c. the set

Sergio039 [100]

Answer:

Option (d).

Explanation:

Karyotype may be defined as the process of the determining of the chromosome complement of the individual organism. The complete set of an organism's chromosome can be determined by karyotype.

The karyotype displays the each and every pair of homologous chromosome. The chromosomes are organised according to their shape and size. The abnormal chromosome can easily be determined by the karyotype.

Thus, the correct answer is option (d).
