Jordan uses a high power objective to observe a specimen under a light microscope. What should he use to focus

11Alexandr11 [23.1K]

Since Jordan needs to use the high power objective in order to view the specimen under the light microscope. He should use the ocular lens in order to view the high power objective which is placed in the objective lenses. So he needs to use the ocular lens for viewing and the objective lens to magnify and see the specimen clearly on the stage.

Rufina [12.5K]

Answer:

Increase the genetic diversity by introducing other subspecies of cougar to the population.

Explanation:

Genetic diversity is the total number of genetic makeup of species. It includes the number of species that have differences within the species and is distinguished from the genetic variability.

The genetic diversity services allow for the population to adapt to the environment and continue to generate more. Thus introducing the subspecies of cougar can be done to save the species from getting extinct.

The net primary productivity is usually more than 80% of gross primary productivity.

fomenos

Answer:

b. False

Explanation:

As GPP stands for the gross primary productivity, it's the total amount of energy produced in the process and the NPP is the net primary productivity. NPP is the difference between the GPP and the energy used by the producer for the process of respiration.

GPP is a continuous and ongoing process that consumes the energy as compared to the NPP that store energy and not being used. Thus, GPP can affect NPP but NPP does not affect GPP.

For example, GPP is completely being dependent on the chlorophyll content of the plant, but NPP is independent of that content of chlorophyll.

The letter X in the diagram below represents what enzyme used in the process shown?

Anvisha [2.4K]

Answer: Option D. RNA polymerase.

Explanation:

Transcription is the process which is used to produce RNA from a DNA template.
The enzyme involved in the process of transcription is RNA polymerase which is responsible for separating the DNA strands and making an RNA which is complementary to the DNA.
RNA polymerase joins the nucleotides in the newly formed RNA strands by utilizing the energy released from the cleavage of the additional phosphate bonds that are removed by it.
The RNA polymerase dissociates from the DNA only after the process of transcription is complete.
