Answer:

The correct answer would be A) gravitropism

Gravitropism or geotropism refers to the differential growth of a plant in response to the gravitational pull.

For example, roots show positive geotropism, that is, they grow in direction of gravitational pull.

In contrast, shoots show negative geotropism, that is, they grow in opposite direction as compared to the direction of gravitational pull.

Mumz [18]

Answer:

D). 8 kg mass

Explanation:

Acceleration of Falling Objects

Heavier things have a greater gravitational force AND heavier things have a lower acceleration. It turns out that these two effects exactly cancel to make falling objects have the same acceleration regardless of mass.

The greater an object's mass, the greater its gravitational force. The earth has a strong attracting force for objects with smaller mass (including the moon), and the sun has an attracting force on the earth and other planets in our solar system. ... The stronger the pull of gravity on an object, the greater its weight.

Beta cells of the pancreatic islets of Langerhans act as glucose sensors, adjusting insulin output in response to blood glucose
LenKa [72]

Answer:

Explanation:

The host's immune response to the transplanted graft, which is commonly exhibited as pericapsular fibrotic overgrowth (PFO), is one of the key causes of defective encapsulated islets in (PFO).PFO creates a barrier upon this capsule surface that inhibits and impedes oxygen and nutrients from entering, resulting in islet cell deprivation, hypoxia, and/or death. This host immune response was missing under in vitro circumstances, which explains why glucose sensing and insulin release were more efficient than in vivo circumstances. Nonetheless, utilizing nanoporous encapsulation or modifying the microcapsular shape and geometry can solve these issues.

Explanation:

The signaling molecules or the proteins that get discharged by the cell infected by the virus to protect the adjacent cells by stimulating a safeguarding defense mechanism are termed as interferons.  

The mentioned proteins obstruct the proliferation of viruses and thus helps the cell in getting rid of the infection. These molecules also assist in stimulating the macrophages and the natural killer cells.
