When we make a rough chemical structure its like -
   br
    I
br-c-br
    I
   br
so as we can see that its having 4 bond pairs of c-br respectively so it qualifies for the hybridisation of sp3(4 bp+ 0 lp) 
thus it gives us a tetrahedral geometrical structure

hope this helps:))

Amylase and starch are mixed and placed at 0 degrees. after the iki test, the solution turns black. a benedict's test yields a n
Fudgin [204]
The starch is not digested.

Amylase is the enzyme that digest starch to Maltose

In iki test, which is also iodine test, it is a test for presence if starch. It turns iodine color from brown to black. Therefore, we know that starch still exist if the color turns black.

Second, benedicts test is a test for reducing sugars, such as glucose or Maltose. Negative results mean no Maltose is detected. So, we can also figure out that no Maltose is produced.

Therefore, the original starch still exists and the product Maltose does not exists, so starch is not digested.

Which of the following structures is NOT found in some prokaryotic cells?
WARRIOR [948]

The answer would be:

Cilium

<u>Here is more about the structures of prokaryotic cells:</u>

Axial filament is a bundle of flagella that are wrapped around the cell's body.

Flagellum is what the prokaryotic cell has that is whip-like in structure. It helps with the motility of the cell.

Pilus is a hair-like structure that are found on the surface of prokaryotic cells. They help the cell attach itself to surfaces.

Peritrichous flagella are several flagella that can be found all over some prokaryotic cells.

What would be the expected effect on plants if the atmospheric CO2 concentration was doubled? What would be the expected effect
Elis [28]

Answer:

C3 plants would have faster growth rates; C4 plants would be minimally affected.

Explanation:

C3 and C4 pathways are the variations of dark reactions of photosynthesis present in green plants. The photosynthetic efficiency of C3 plants is reduced due to the affinity of RuBisCo enzyme for oxygen which in turn leads to the futile pathway of photorespiration. RuBisCo enzyme catalyzes the rate-limiting reaction of the C3 pathway. On the other hand, the C4 plants concentrate CO2 around RuBisCo in their bundle sheath cells of leaves to minimize photorespiration and exhibit higher rates of photosynthesis.

Increased levels of atmospheric CO2 would reduce the photorespiration in C3 plants and would allow them to fix CO2 efficiently due to the increased concentration of CO2 around the enzyme RuBisCo. The increased photosynthetic efficiency would help these plants to exhibit faster growth rates.

However, the photosynthetic rate of C4 plants is not limited by CO2 concentration as they themselves reduce photorespiration by spatial separation of primary carboxylation in mesophyll cell and CO2 fixation in bundle sheath cells. Hence, increased CO2 levels in the atmosphere would not have any impact on their photosynthetic rate and growth.

The smooth, connective tissue lining that covers the opposing bony surfaces of a synovial joint is called?
UkoKoshka [18]

Answer:

The Articular cartilage.

Explanation:

Articular cartilage is the smooth, white tissue that covers the ends of bones where they come together to form joints. Healthy cartilage in our joints makes it easier to move. It allows the bones to glide over each other with very little friction. Articular cartilage can be damaged by injury or normal wear and tear.
