Answer:

Desmosomes

Explanation:

Desmosomes are cellular structures that adhere to neighboring cells. Its function is to hold the epithelial cells together, associating the intermediate filament cytoskeletons of neighboring cells, thus forming a transcellular network with high resistance to mechanical traction. It thus allows the cells to maintain their shape and the epithelial sheet to exist in a stable form. Inside cells act as anchoring sites for intermediate rope-shaped filaments, which form a structural network in the cytoplasm providing a certain rigidity. Through these junctions the intermediate filaments of the adjacent cells are indirectly connected forming a continuous network that extends throughout the tissue.

Answer:

Oxygen.

Explanation:

Oxygen molecule that is produced in the light dependent reactions. This shutting down of linear electron flow greatly affected the production of oxygen. Photosystem II gains replacement electrons from splitting of water molecules into hydrogen ions (H+) and oxygen atoms so if the electron flow is disturbed then oxygen production is greatly affected.

gove one example of how advances in science and technology have allowed the human population to increase rapidly

natima [27]

One example: The improvement in science and technology over the years has decreased the infant mortality rate. Since more babies live, we have a higher population.

Also, with increases in science and technology, there are many diseases that were once considered fatal that are now easily treated. This has also led to a higher population.

In pea plants, the allele for tall stalks (T) is dominant over the allele for short stalks (t). Suppose a cross between a tall p

vazorg [7]

Answer:

Tt - 1/2

tt - 1/2

Explanation:

<em>A cross between a tall pea plant and a short pea plant that produces 43 tall and 47 short offpsring (almost 1:1) is most likely a cross involving a heterozygous tall individual and a homozygous short individual.</em>

Tt x tt

Offspring = Tt Tt tt tt (50% tall and 50% short)

If one of the tall offspring (Tt) is crossed with one of the short offspring (tt):

Tt x tt

Offspring = Tt Tt tt tt

Genotype ratio = 2Tt:2tt

Hence,

Tt = 1/2

tt = 1/2

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
