Scientists studying the passage of genetic materials of the T2 bacteria phage during infection prepared two batches of phages. B

atch I is prepared in the presence of 35S. Batch II is prepared in the presence of 32P. Scientists used the two batches of phages to infect bacteria grown in medium that did not contain 35S or 32P, and then isolated the progenies.What proportions of the progenies of Batch I and Batch II phages would be labeled

Conservation biologists are concerned with conserving the three levels of biodiversity on the planet

  • The first level is genetic diversity, or variety, which is especially vulnerable in small populations.
  • Small populations are more prone to lose alleles due to non-random mating events and the extinction of individuals with unique gene combinations.
  • The second level is species diversity, which is defined as the quantity and relative abundance of species in a particular region.
  • Conservation biologists are engaged in helping to safeguard as many species as possible, with a focus on threatened or endangered species.

The third level is ecosystem diversity, which considers an area's structure and function.

Write how an ecosystem of your choice is organized. Identify each level. Include biotic and abiotic examples.
8_murik_8 [283]
(Bottom to top)
Biosphere- The ecosystem comprimising the entire Earth & the living organisms that inhabit it. Example: Where life occurs on, Earth
Biome- A large naturally occuring community of plants and animals Example: Rainforest, Tundra, Desert, Marine, Grasslands,  etc 
Ecosystem- A community of living organisms  called producers, conumers, decomposers. Example: Plants (Producers) Rabbits (Consumers) Worms (Decomposers)
Community- Interacting group of various species Example: A forest of trees inhabited by animals.
Population- Traits of a group of plants and animals Example: 4 rabbits have broenn fur and 2 have black fur in a group.
Individual- Individual organisms Example:  An otter is a organism
Abiotic examples- Air, soil, sunlight, or water
Biotic examples- A frog, a leaf, or a tree

A pure-breeding fruit fly with curled wings mates with a pure-breeding fruit fly with normal (straight) wings. The F1 mate with
vesna_86 [32]

Answer:

The dominant curled wing allele is also a recessive lethal.

Explanation:

If we look at the F2 ratio we see that :  

curled wings: straight wings= 160:80

                                               =2:1

Hence,  if curled wings is considered to be a dominant trait then Curled wings * straight wings

Dd x dd

Punnet square will be as follows :

           d                    d

D   |    Dd   |        Dd

d    |    Dd   |        dd

Hence in order to get F2

Dd x dd

Punnet square will be the same as above if the F1 cross is Dd* Dd

        D    d

D DD Dd

d Dd dd

if DD is lethal then the ratio is

Dd:dd=2:1

that is curled wings: straight wings=2:1

Hence, The dominant curled wing allele is also a recessive lethal.
