STOP & JOT: Parasites rarely kill their hosts right. Instead they keep them alive as long as needed. In fact, the best
Masteriza [31]

Answer:

Parasites would not want to kill their host cells immediately because they want their food source or keep getting food, not to kill their food source (host cell). Parasites live on another living host cell for their survival, they depend on host organisms to gets an energy source, without the host cell they can't live, develop and multiply.

Mostly, if the host cell dies then the parasite also can't able to grow or reproduce and it will also die. So that they don't want to kill their host's cell immediately.

Why are the colors different on the planet at different times of the year ? Give a specific example.
Reptile [31]

Answer:

In the Northern Hemisphere, ecosystems wake up in the spring, taking in carbon dioxide and exhaling oxygen as they sprout leaves — and a fleet of Earth-observing satellites tracks the spread of the newly green vegetation.

Meanwhile, in the oceans, microscopic plants drift through the sunlit surface waters and bloom into billions of carbon dioxide-absorbing organisms — and light-detecting instruments on satellites map the swirls of their color.

Satellites have measured the Arctic getting greener, as shrubs expand their range and thrive in warmer temperatures. Observations from space help determine agricultural production globally, and are used in famine early warning detection. As ocean waters warm, satellites have detected a shift in phytoplankton populations across the planet's five great ocean basins — the expansion of "biological deserts" where little life thrives. And as concentrations of carbon dioxide in the atmosphere continue to rise and warm the climate, NASA's global understanding of plant life will play a critical role in monitoring carbon as it moves through the Earth system.

When doing medical research with human subjects, which four limitations are un voidable?
viva [34]

The four limitations are

1.It's often impossible to repeat trials on the same subjects.

2-Subjects may report an inaccurate medical history.

3-It can be difficult to control all possible variables.

4-It's impossible to come up with testable scientific questions for human subjects.

Research involving human beings is ultimately necessary for improvements in human health and welfare. Any results about healthy physiology, illness causes, treatment effectiveness, learning, or behavior must be verified by carefully controlled investigations involving human participants. Sadly, not all human research have been valid and beneficial. It is possible to harm people in the name of research. The most well-known instances happened in Nazi Germany. Investigations conducted after the war found several crimes, including experiments in which participants were submerged in extremely cold water to determine how long it would take them to pass away from hypothermia.

When Charles Darwin published his radical theory of evolution by natural selection in 1859 it was attacked by many early biologi
irina1246 [14]

Answer:

Empirical evidence of his ideas

Explanation:

The scientific process involves the formulation of hypotheses that enable to answer questions about the real world, and then to carry out experiments or observations that are used to confirm (or reject) such predictions. In the last 160 years, Darwin's ideas on 'descent with modification' have constantly been subjected to experimental assessment, and obtained data confirmed his observations. For example, molecular evidence based on the DNA and RNA -which constitute the genetic material of all living organisms- has shown the conservation of this process. In consequence, molecular evidence has been used to construct 'evolutionary' phylogenetic trees from DNA/RNA sequences. Moreover, evidence in genetics has shown the critical role played by mutations in the mechanism of natural selection proposed by Darwin, thus also confirming his theories. These are only some examples, and supporting evidence confirming Darwin's ideas has been collected from different research fields ranging from ecology to molecular biology.
