Prompt
Orlov [11]

Answer:

Energy in an ecosystem is mainly made by the producers of an ecosystem. The net primary productivity in an ecosystem depends on many factors. Some of them are:

  • Amount of sunlight: The amount of sunlight that the plants and trees might be has basic influence on the primary productivity. Plants and trees receiving enough sun light will be able to make more food for organisms living in that area as compared to the producers which do not receive enough sun light.
  • Soil texture: The soil texture and the availability of nutrients heavily influence the primary productivity of an ecosystem. An area having a soil texture with not enough nutrients will not be able to grow more plants. As a result, the productivity would decrease.

A scientist wants to determine whether a mutant phenotype is due to the loss of gene C or gene D, which are both deleted in a mu
klio [65]

Answer:

a transgenic copy of the gene C is sufficient to restore normal eye development

Explanation:

In genetics, there are diverse approaches to determining a gene's function. For example, it is possible to use a complementation test to determine loss-of-function recessive mutations when it is unknown if such mutations fall in the same or in different genes. Similarly to the generation of loss-of-function phenotypes, it is possible to insert a gene and thus produce a gain-of-function mutation that restores normal gene function (i.e., to restore the wild phenotype). Moreover, transgenic organisms refer to genetic engineering techniques by which any foreign or modified gene is inserted in the genome of an organism, which can also be used to study gene function. In this case, the restoration of the normal phenotype (wild-type eyes) is associated with the expression of the transgenic gene C, thereby evidencing that the gene C is required for normal eye development. In the last years, transgenic models have shed light on developmental pathways and on gene function.
