Which best describes the relationship between two species and a niche?If two species have the same niche, one species will always become extinct.
Two species are able to occupy the same niche in the same habitat.
Two species cannot occupy the same niche in the same habitat.
If two species have the same niche, one species will always move.

Answers

Answer:

If two species have the same niche, one species will always move.

Explanation:

In biology, ecological NICHE refers to how the species of an organism performs in its ecosystem i.e. its role. Niche includes the reproduction, feeding pattern, prey, etc. However, if there are two species occupying the same niche, one species will always move.

One of the species, usually the weak one, will always move because occupying the same niche by two species will inevitably lead to competition, which causes one of the species to go elsewhere when these resources are limited.

If two species have the same niche, one species will always become extinct. This is known as the competitive exclusion principle. Hence option A is correct.

It states that two species cannot occupy the same niche in the same habitat and stably coexist. This is because they will compete for the same resources, and one species will eventually outcompete the other.

The only way for two species to occupy the same niche in the same habitat is if they have some kind of mechanism to prevent competition. For example, two species of birds may have different beak shapes that allow them to eat different types of food. This is known as resource partitioning.

If two species have the same niche and no mechanism to prevent competition, then one species will eventually become extinct. This is because the species that are better adapted to the environment will outcompete the other species and eventually drive it to extinction.

Therefore, the correct option is A.

1) A fever is initiated by elevating the setpoint of the hypothalamic ‘thermostat’. a) What will happen to the metabolic rate once the setpoint has been raised? Please explain your answer briefly.

Answers

Thermostat

Explanation:

  • The body tightly regulates the body temperature through a process called thermoregulation, in which the body can maintain its temperature within certain boundaries, even when the surrounding temperature is very different
  • The core temperature of the body remains steady at around 36.5–37.5 °C (or 97.7–99.5 °F)
  • The hypothalamus in the brain is the master switch that works as a thermostat to regulate the body’s core temperature
  • The nervous system constantly relays information about the body's temperature to the thermostat, which in turn activates different physical responses designed to cool or warm the body, depending on the circumstances
  • Responses may include: decreasing or increasing the flow of blood from the body's core, where it is warmed, to the surface, where it is cooled; slowing down or speeding up the rate at which the body turns food into energy (metabolic rate);inducing shivering, which generates heat through muscle contraction; and inducing sweating, which cools the body through evaporation
  • A fever occurs when the thermostat resets at a higher temperature, primarily in response to an infection
  • To reach the higher temperature, the body moves blood to the warmer interior, increases the metabolic rate, and induces shivering
  • The chills that often accompany a fever are caused by the movement of blood to the body's core, leaving the surface and extremities cold; Once the higher temperature is achieved, the shivering and chills stop

Humans originated in Africa about 7 million years ago: if life on earth started 3.5bya ago and represented 24 hours from then to today, how many minutes of these 24 hours would be devoted to this 24-hour clocka) since the first humans showed up?
b) since Humans showed up 300,000 ya?

Answers

I don’t quite understand the answers that you’ve provided to choose from, but if we are comparing those millions of years to a 24 hour clock, then humans have only been around for 2.88 minutes of out the entirety of life on Earth.

If the rice already had the genes that could make vitamin A, why did scientists use genes from other organisms?A. The rice genes didn't make the right type of vitamin A.
B. It's easier to introduce genes from one species into another than from just one species.
C. Scientists could have just "turned on" the rice genes, but they wouldn't have learned anything from that process.
D. It's easy to extract genes from bacteria.
E. The scientists didn't know how to "turn on" the genes in the rice.

Answers

Answer:

A. The rice genes didn't make the right type of vitamin A.

Explanation:

Regular white rice does not have the gene to produce beta carotene. The human body converts the beta carotene into vitamin A.

To increase the nutritional value of rice, the gene for beta carotene from daffodil flowers was inserted into the cells of endosperm of rice.

This allowed these cells of the genetically engineered rice varieties to produce beta carotene. Production of beta carotene imparted golden color to the rice grain and hence, the name.

John Needham, Louis Pasteur, and other scientists all performed experiments to disprove ______. a) spontaneous generation
b) evolution
c) Koch's postulates
d) binomial nomenclature

Answers

The theory of spontaneous generation is an experiment that tries to prove the possibilities that living organisms can be produced from non-living origins.

This experiment was first done by Francesco Redi in 1668. However, several scientists such as John Needham, Louis Pasteur, John Tyndall amongst other scientist tried to disprove the theory of spontaneous generation.

The theory was later disproved by Louis Pasteur and John Tyndall in the mid-19th century.

Answer:

A) spontaneous generation

Explanation:

Spontaneous Generation theory stated that living organisms could be spontaneously generated from non-living matter. Francesco Redi conducted an experiment similar to the one Louis Pasteur would do nearly 200 years later. The 17th-century Italian developed a spontaneous generation experiment that showed that maggots do not spontaneously emerge from decaying meat.
