Which enantiomer of thalidomide cause birth defects?.

1 answer:

8 0

The (R)-enantiomer is an effective sedative medication and the (S)-enantiomer may be teratogenic. (S)-Thalidomide was shown to be responsible for over 2000 cases of birth defects in children born to women who took the drug during pregnancy (Figure

A population of white rabbits and brown rabbits both live in a temperate deciduous forest where the summers are mild and average

Svetach [21]

Answer:

Q: ...what do you expect to happen to the population of each color of rabbit?

A: The white rabbit population may slowly die off while the brown rabbit population thrives and reproduces.

Explanation:

The white rabbits are well adapted to survival in cold winter months and snowfall, where they may camouflage effectively to avoid predation. However, the brown rabbits, more adapted to warmer periods in the fall, spring and summer in the temperate deciduous forest; the trees lose their leaves before cold seasons.

Leaf litter and foliage in warmer months likely provides better camouflage for brown rabbits. Camouflage is an adaptation to predation; the rabbits blend into surrounding colors, textures and patterns to avoid detection. In the onset of shorter winters, the white rabbits will be unable to avoid predators without snow to blend into; they would contrast with their surroundings making them easy targets to be hunted. Thus, with extended periods of warm temperatures, brown rabbits are more likely to survive and reproduce leading to a thriving population.

The division of a bacterial cell into two daughter cells (called binary fission) is accomplished by a protein called FtsZ. FtsZ

Katena32 [7]

The question is incomplete and the complete question is:

For each space in the table, drags the appropriate label to indicate if the statement is true or false for each group of organisms

1. Cells divide by constriction of a ring of protein

2. The presence of a cell wall prevents the cell from diving by constriction

3. Tubulin or tubulin-molecules function in binary fission(in bacteria) or cytokinesis(in animals and plants)

Answer:

1. Bacteria: true , Animals: true and Plants: false

2 bacteria: false , Animals: false and Plants: true

3. Bacteria: true , Animals: false and Plants: true

Explanation:

Option-1

Bacteria: true as the protein FtsZ is involved in the binary fission and the formation of constriction.

Animals: true as the microtubule ring is formed

Plants: false as no constriction of the ring is formed instead of a cell divides by plate formation

Option-2

 Bacteria: false as the ring is formed and no cell wall is involved

Animals: false as there is no cell wall in the animals

Plants: true as the cell wall divides by plate formation

Option-3

Bacteria: true as FtsZ is involved in the ring formation which is tubulin like structure

Animals: false as the actin and myosin are involved in a ring formation

Plants: true as tubulin are involved
