Lina20 [59]3 years ago
5 0

Answer:

Chiasma

Explanation:

During meiosis, more precisely, prophase 1 homologous chromosomes  connect in a process known as synapsis and form tetrad structure (four chromatides). Non-sister chromatids mayrecombine with their homologous partner which is known as crossing over, the process in which genetic variabilty is produced. These non-sister chromatids remain physically connected at the points of exchange known as chiasmata.

true

Explanation:

Cerebrospinal fluids  is a  colorless fluid  that is secreted in the choroid plexus,and  circulates in the ventricles system  and sub -aranchinoid space  of the brain and spinal cord. its provides nutrients  to the surrounding  neurons, cushions the effects of trauma, pressure, acts as buffer and provides protection through immune  system .

it plays a vital role in regulating  blood flow, through a process called cerebral auto regulation,This is needed to maintain efficient cerebral blood flow of oxygen and other metabolites, and withdraw of metabolic wastes from the brain.

in order to analyze it to diagnose some neurological diseases  its sample is usually taken out in a process called lumbar  puncture.

krek1111 [17]

Answer:

The activity which causes the least amount of wetland and estuary degradation when it occurs near the coast is:

A. dune grass rehabilitation

Explanation:

This is actually a rehabilitation effort, unlike the other three options that cause land degradation.  A dune grass rehabilitation accretes sand and minimizes the rates of beach erosion. The program tries to protect coastal infrastructure and upland properties from storm damage by planting vegetation, fencing off sensitive areas, blocking storm surge, creating dune walkways, and absorbing wave energy.  During dune grass rehabilitation, activities that adversely affect the dunes are avoided.
