BRAINLIEST TO FIRST CORRECT. 1. What can scientists learn about by studying Ice? (Air Temperature, Ocean Temperature, Carbon Dioxide Levels, Kinds Of Plants, or Rainfall)?
2. What can scientists learn about by studying Chemical Isotopes In Foraminifera? (Air Temperature, Ocean Temperature, Carbon Dioxide Levels, Kinds Of Plants, or Rainfall)?
3. What can scientists learn about by studying Fossilized Pollen Grains? (Air Temperature, Ocean Temperature, Carbon Dioxide Levels, Kinds Of Plants, or Rainfall)?
4. What can scientists learn about by studying Tree Rings? (Air Temperature, Ocean Temperature, Carbon Dioxide Levels, Kinds Of Plants, or Rainfall)?

Answers

The answer to the questions are :

  • Ocean Temperature, Carbon Dioxide, Air Temperature
  • Carbon Dioxide Levels
  • Kinds Of Plants.
  • Kinds Of Plants, or Rainfall.

What do scientists learn form their studies  ?

The scientists learn from the ice cores about the air and other ocean temperatures and also get to know about the Carbon dioxide levels. The scientists studying Foraminifera get to learn about the amount of carbon dioxide in the air. By analysis of the pollen they learn about the changes in vegetation. From the tree rings, they learn about the tress and weather conditions.

Final answer:

Scientists can learn about past air temperatures and carbon dioxide levels from ice cores, past ocean temperatures from chemical isotopes in foraminifera, historical plant types from fossilized pollen grains, and past air temperatures and rainfall from tree ring patterns.

Explanation:

By analyzing different proxies, scientists can deduce valuable information about Earth's past climate and environmental conditions. Here are the specific insights gained from the proxies mentioned:

  • Ice: Studying ice cores, especially from Antarctic ice, enables scientists to determine historical air temperature, carbon dioxide levels, and more by examining trapped air bubbles and biological substances.
  • Chemical isotopes in Foraminifera: By analyzing these isotopes, scientists can deduce past ocean temperatures based on the coiling direction of the Foraminifera's shells found in sediment cores.
  • Fossilized pollen grains: These can indicate the kinds of plants that were present historically, which, in turn, reflects climate conditions and local ecosystems.
  • Tree rings: The number and characteristics of annual rings in trees can reveal historical air temperature and rainfall patterns, as well as environmental conditions and events like droughts or volcanic eruptions.

The principles of probability can be used toA. decide which organisms are best to use in genetic crosses.

B. predict the traits of the offspring of genetic crosses.

C. determine which species should be used in genetic crosses.

D. determine the actual outcomes of genetic crosses.

Answers

Answer:

Option B, predict the traits of the offspring of genetic crosses

Explanation:

Lets see an example -

Suppose there are two adult cats , where female cat has brown (BB)haired and it is a dominant trait while male cat is recessive grey (bb) haired organism.

If a cross is carried out between these two species then through probability it can be derived that how many species will be grey (Bb) haired

Let see the punnet square for the cross-

B B

b Bb Bb

b Bb Bb

Thus out of four offspring’s produced all the offspring’s are grey (Bb) colored. Thus, there is a 100% probability that if a cross is carried out between female cat having brown hair (BB) and a male cat having black hair (bb), the offsprings will have grey (Bb) hair.

In this way probability can help to predict the traits of the offspring of genetic crosses

The laws of probability can be applied to genetics to make predictions about the traits of the offspring that result from genetic crossings. Therefore, the correct option is B.

Probability enables us to calculate the likelihood that specific characteristics will be inherited, based on the known genetic information of the parent organism. Scientists can predict the possible combinations of genetic characteristics in offspring by understanding the principles of heredity and applying probability calculations.

Probability can forecast and infer, but it cannot predict the actual results of genetic crosses because these are affected by various processes, including random segregation during meiosis and genetic recombination.

Therefore, the correct option is B.

Transcribed image text: Effect of flow tube Length 4. How does increasing the flow tube length affect fluid flow? Explain why changing blood vessel length would or would not be a reasonable method for the body to control blood flow. Effect of Pressure 5. How does decreasing the pressure affect fluid flow? Describe what happens to pressure and flow during exercise and explain why they change in that way. Effect of Stroke Volume 6. Cardiac Output = Stroke Volume x Heart Rate a) What happened to the pump's rate as its stroke volume was increased? What happened to cardiac output? b) What do you think might happen to the pressure in the pump during filling if the valve in the right flow tube became leaky?

Answers

Increasing the flow tube length decreases fluid flow. Changing blood vessel length would not be a reasonable method for the body to control blood flow because it would require significant energy and time. Decreasing the pressure decreases fluid flow. During exercise, pressure and flow increase because the body needs more oxygen and nutrients. Increasing stroke volume increases cardiac output. If the valve in the right flow tube became leaky, the pressure in the pump during filling would decrease.

Positive feedback is most like _____.

Answers

Positive feedback is most like adding wood to a burning fire to increase the heat.

Positive feedback is a regenerative feedback process in which a segment of the output is combined with the input for the output to increase more. Components of a positive feedback loop include a stimulus or change, a sensor, a control center and an effector.  Examples of positive feedback include the process of labor and childbirth and blood clotting.

Potatoes were the main crop in Ireland in the 1800s. Almost the entire population of Ireland was dependenton a single variety of potato, the “lumper.” These potatoes were reproduced by a method of asexualreproduction known as vegetative propagation. In the middle of the 1800s, a disease caused by a funguskilled almost the entire lumper crop within two years. As a result, millions of people in Ireland died of starvation.The most likely reason the potato disease was able to destroy the potato crop in such a short time is that the(1) potato population lacked variations(2) lumper variety had a long reproductive cycle(3) lumper had several variations caused by vegetative propagation(4) potato population in Ireland utilized all of the finite resources
