Answer:
The correct answer is a increase in 3-phosphoglycerate levels and a decrease in RUBP levels.
Explanation:
NADPH is a reducing equivalent that is produced during light reaction of photosynthesis.The NADPH that is produced during light react is utilized in the dark reaction.
A decrease NADPH formation in the chroloplast will in turn decrease the formation of PGALD from phosphoglyceric acid(PGA).Some PGALD are used in the regeneration of ribulose bis phosphate(RUBP).
From this point of view it can be stated that decrease in NADPH level decreases PGALD level which in turn decreases RUBP levels.
As NADPH production is decreased in the chloroplast more phophoglyceric acid or 3-phosphoglycerate will accumulate thus the cellular level of PGA is increased.
Answer:
Genetic diversity: Some individuals in a population of wild rabbits are resistant to a new disease.
Ecosystem diversity: If the population of wild rabbits decreases, a bobcat can switch its diet to squirrels or woodchucks.
Species diversity: Populations of wild rabbits from a forest and from a neighboring meadow can interbreed, which increases variation.
Biodiversity of an ecosystem is usually explored by three diversities which are responsible for ecosystem stability they are : genetic diversity, ecosystem diversity and species diversity.
Genetic diversity is the variety of genes within a population of species. Each species consists of individuals bearing different genetic composition. Some individuals in a population of wild rabbits are resistant to a new disease because they exhibit genetic diversity within the population as a consequence some individuals exhibit genes which protect them against new disease.
Species diversity is the variety of species within an ecosystem. Populations of wild rabbits from a forest and from a neighboring meadow can interbreed, which increases variation is an example of species diversity. The wild rabbits from a forest and a neighboring meadow are two species living in an ecosystem stating the diversity of species in an ecosystem.
Ecosystem diversity is the variety of ecosystems in a given region.If the population of wild rabbits decreases, a bobcat can switch its diet to squirrels or woodchucks is an example of ecosystem diversity because in an ecosystem there is interaction of organisms as predator prey relationship. This example is also relating with predator prey relationships in an ecosystem.
Answer:
The correct answer is option C. "arg+leu– or arg–leu+".
Explanation:
This bacteria is not able to growth on minimal medium or minimal medium supplemented with leucine. This means that the bacteria needs external supplementation of amino acids to growth, either arginine or leucine. Therefore, this bacteria can have the genotypes of arg+leu– or arg–leu+, meaning that the bacteria is able to synthesize either of two amino acids, but not both, because if that was the case the bacteria would be able to growth on minimal medium.
Answer:
Genotypic and Phenotypic ratios → 1:1:1:1
- 25% of the progeny is expected to be SsWw, exhibiting spotted skin and wooly hair, SsWw
- 25% of the progeny is expected to be Ssww, exhibiting spotted skin and non-wooly hair, Ssww
- 25% of the progeny is expected to be ssWw, exhibiting non- spotted skin and wooly hair, ssWw
- 25% of the progeny is expected to be ssww, exhibiting non-spotted skin and non-wooly hair, ssww
Explanation:
<u>Available data</u>:
- spotted skin (S) is dominant over non-spotted skin (s)
- wooly hair (W) is dominant over non-wooly hair (w)
- Cross: heterozygous spotted, non-wooly mammoth with a heterozygous wooly-haired, non-spotted mammoth.
Parentals) Ssww x ssWw
Gametes) Sw, Sw, sw, sw
sW, sW, sw, sw
Punnett square) Sw Sw sw sw
sW SsWw SsWw ssWw ssWw
sW SsWw SsWw ssWw ssWw
sw Ssww Ssww ssww ssww
sw Ssww Ssww ssww ssww
F1) 4/16 = 1/4 = 25% of the progeny is expected to be SsWw, exhibiting spotted skin and wooly hair
4/16 = 1/4 = 25% of the progeny is expected to be Ssww, exhibiting spotted skin and non-wooly hair
4/16 = 1/4 = 25% of the progeny is expected to be ssWw, exhibiting non- spotted skin and wooly hair
4/16 = 1/4 = 25% of the progeny is expected to be ssww, exhibiting non-spotted skin and non-wooly hair.
Genotypic and Phenotypic ratios → 1:1:1:1
A-G-T-C-G-T or in other words the answer is C
