Convergent evolution suggests different organisms evolved _ due to _. similarly; different environments differently; different environments differently; similar environments similarly; similar environments

Answers

Answer 1

Answer:

The answer is similarly; similar environments.

Convergent evolution suggests different organisms evolved similarly due to similar environments.

Convergent evolution is a phenomenon of independent evolution of similar traits in species that are in different lineages. These traits are similar in form or function but were not present in the last common ancestor of those species.

There are many examples of convergent evolution among plants and animals.
Among the plants, both cactus and euphorbia are succulent plants, have spines, live in the deserts, but they belong to the different families.
Among the animals, dolphin, which is a mammal, is more similar to fish, than to other mammals. Or, both birds and bat, which is the mammal, have wings.

So, all these examples of convergent evolution suggest that the living in the similar environmental conditions led to development of similar forms between distinct species.

Answer 2

Answer:

The answer is similarly; similar environments.

What is the cell cycle??

Answers

The series of events that take place in a cell leading to its division and duplication (replication) that produces two daughter cells.

The cell cycle, or cell-division cycle, is the series of events that take place in a cell leading to its division and duplication (replication) that produces two daughter cells. In cells without a nucleus (prokaryotic), the cell cycle occurs via a process termed binary fission. Hope I helped:)

The answer is B. Cholera

The other options are caused by a virus. Cholera was caused by bacterium Vibrio Cholera. The classic symptom of cholera is diarrhea that lasts for a few days. It could result in life threatening dehydration and electrolyte imbalance

Cholera is infected between 3 - million people worldwide, while it's considered as a pandemic, it rarely happens in a developed country like the U.S.A.

Researchers are conducting a study to see if exposure to an occupational toxin leads to brain tumors. The researchers recruit 1,000 men who work at a steel factory (all of whom do not have a brain tumor in 2000) and use questionnaires as well as measuring devices to see who is exposed to the occupational toxin Airflyte. After the baseline assessment, 493 of the workers were exposed to Airflyte while the others were not. After 10 years of follow up, 308 of the workers exposed to Airflyte developed brain tumors while 77 of the men not exposed to Airflyte developed brain tumors. Set up a 2x2 table with the data given.

Answers

Answer:

Explanation:

Based on the information provided, we can set up a 2x2 table to summarize the data as follows:

| Brain Tumor | No Brain Tumor | Total

--------------------------------------------------------

Exposed to Airflyte | 308 | 185 | 493

--------------------------------------------------------

Not Exposed | 77 | 430 | 507

--------------------------------------------------------

Total | 385 | 615 | 1000

In this table, the rows represent the exposure status (exposed to Airflyte or not exposed), and the columns represent the occurrence of brain tumors (brain tumor or no brain tumor). The totals are calculated for each category.

Please note that the numbers provided in the table are based on the given data and do not reflect any statistical analysis or conclusions about the relationship between exposure to Airflyte and the development of brain tumors. Further statistical analysis, such as calculating risk ratios or conducting hypothesis tests, would be necessary to determine the strength of the association between the exposure and outcome variables.

Final answer:

A 2x2 table is set up to represent the brain tumor occurrence and non-occurrence in workers who were and were not exposed to the occupational toxin Airflyte. There were 308 cases of tumors in the exposed group and 77 in the non-exposed group. The rest did not develop tumors.

Explanation:

In conducting this study, the researchers divided the 1,000 men into two groups: those exposed to the occupational toxin Airflyte and those not exposed. By using a 2x2 table, we can clearly illustrate the results obtained after the 10-year follow up. Here's how it looks:

With Brain Tumor Without Brain Tumor

Exposure to Airflyte

308 493 - 308 = 185

No Exposure to Airflyte

77 507 - 77 = 430

This table helps to visualise the observed differences in brain tumor development among the workers who were exposed to the toxin compared to those who weren't exposed.

Orange roughy fish are a fourth-level consumer. We may see fifth- or sixth-level consumers, but not as many as at lower levels on a trophic pyramid. Why are the upper levels of a tropic pyramid limited?

Answers

As energy is lost through the energy pyramid, where it is the primary producers at the base, the upper levels of a tropic pyramid are limited as there is less to consume from as you go down the pyramid.

Answer:

An ecological pyramid is a graphical representation of the distribution of the biomass to different organisms in successive trophic levels. The energy is being lost by 10% in every higher trophic level, when one organism is consumed by another organism in a food chain. Therefore, the number of trophic levels in a pyramid will be limited.
