Daphnia are freshwater organisms sometimes referred to as “water fleas.” Design an experiment thatcould be used to test the effects of temperature on the size of a daphnia population. In your
experimental design, be sure to:
• state a hypothesis to be tested
• describe how the control group will be treated differently from the experimental group
• identify the independent variable in the experiment
• identify the type of data that will be collected

Answers

Answer 1
Answer: An experiment is where scientific data is gathered and analysed to form inferences. Moreover, we can establish a testing ground on the daphnia population, let say by embryology. Hence, we can observe ina controlled manner how temperature influences the growth and formation of offspring by mothers of the daphnia population considering that offspring can contribute to population growth. 
Answer 2
Answer:

Answer

• state a hypothesis to be tested

Development rate increases faster with temperature that growth rate

• describe how the control group will be treated differently from the experimental group

The control group will be raised at 8 different temperatures to assess their size at maturity, and their asymptotic size.

• identify the independent variable in the experiment

3 clonal lines that differ in asymptotic size and growth rate.

• identify the type of data that will be collected

Measurements of the individual length of Daphnia

Explanation

In this experiment, the temperature-size rile(TSR) was utilized where it will be found that responses on temperature size observed at maturity is different from that manifested at asymptotic size. It will be observed that thermal shift in resources allocation may completely or partly result to a thermal plasticity in maturity size. Moreover, it will be seen that thermal plasticity in asymptotic size is controlled by temperature related challenges.

E. The best fossils are preserved in tar.

Answers

Answer:

1,3,4 are correct

Explanation:

The real answer

if you would think back to what you've been learning this whole time....

is

1.) They give clues about Earth’s climate in the ancient past.

ex: think about sediments and their purpose is to show the time the deeper you go the more you know

3.)Fossils show what Earth was like millions of years ago.

ex: basically supported by answer 1

4.)Fossils can be found in ice.

ex: if not why didn't you watch ICE AGE the movie!!!

XD JK

apparently even mammoths were found in the Ice completely fossilized

Which RNA base pairs with the adenine in DNA?

Answers

In DNA, adenine base pairs with thymine. In RNA, adenine pairs with uracil.

DNA Base Pairing:

  • In DNA, there are four nitrogenous bases: adenine (A), thymine (T), cytosine (C), and guanine (G).
  • Adenine (A) always pairs with thymine (T), forming an A-T base pair.
  • Cytosine (C) always pairs with guanine (G), forming a C-G base pair.
  • These complementary base pairs are essential for maintaining the double-stranded structure of the DNA molecule. The hydrogen bonds between the base pairs hold the two strands of DNA together.

RNA Base Pairing:

  • In RNA, there are also four nitrogenous bases: adenine (A), uracil (U), cytosine (C), and guanine (G).
  • Adenine (A) in RNA pairs with uracil (U), forming an A-U base pair.
  • Cytosine (C) in RNA still pairs with guanine (G), forming a C-G base pair.
  • Unlike DNA, RNA is typically single-stranded, but it can form temporary secondary structures due to base pairing.

Role in Transcription:

  • During the process of transcription, a segment of DNA is used as a template to synthesize a complementary RNA molecule.
  • When RNA polymerase reads the DNA template, it selects ribonucleotides (A, U, C, and G) that are complementary to the DNA template strand.
  • Adenine (A) in DNA is transcribed into uracil (U) in RNA, thymine (T) in DNA is transcribed into adenine (A) in RNA, and the other base pairs remain the same (C-G and G-C).
  • This complementary base pairing is fundamental to the flow of genetic information from DNA to RNA and is a key concept in molecular biology and genetics.

Get it?1. Explain the factors that

of the human population.
How have these factors
contributed to the
homeostasis of the
population within its
environment? Explain.

Answers

Answer:

I am answering just from my knowledge

The factors that have contributed to an increase in human population are two main e.g Increase in birth rate and decrease in death rate.

Increase in birth rate is due to more food production and food supply.Massive increase in agricultural productivity.More life expectancy etc.There is a decrease in death rate beacauseof eradication of diseases,better hygiene,cleanliness and development in medical facilities. Similarly, populations of organisms respond to external factors for a collective benefit. All populations must have an adequate amount of food, water, shelter, and space. ... Biotic factors like predation and competition for food are also limiting factors.the technologies used to achieve this transformation have caused unprecedented changes to Earth’s environment, altering ecosystems to the point where some may be in danger of collapse. The depletion of the ozone layer, erosion due to acid rain, and damage from global climate change are caused by human activities. The ultimate effect of these changes on our carrying capacity is unknown. As some point out, it is likely that the negative effects of increasing carrying capacity will outweigh the positive ones—the world’s carrying capacity for human beings might actually decrease.good luck

Final answer:

The increase in the human population's survival rate can be attributed to advances in medical technology, improved sanitation, and enhanced nutrition.

Explanation:

Several factors have significantly contributed to an increase in the survival rate of the human population and consequently to its homeostasis within its environment. Among these key influences include advances in medical technology, improved sanitation, and enhanced nutrition.

Medical technology advancements, such as vaccinations and antibiotics, have significantly reduced mortality rates, especially among infants and children. Coupled with an overall improvement in healthcare services, these interventions have extended life expectancy.

Improved sanitation has also played a significant role in increasing the survival rate. Access to clean water and waste disposal systems prevent the spread of disease, improving overall public health. Moreover, legislation and increased awareness of hygiene principles have made environments safer for human habitation.

Furthermore, an enhanced nutrition contributes to a healthier population, building immunity and strengthening the human body against illnesses. Expansion of food production technologies and improved transport infrastructure have ensured more balanced diets for a larger portion of the population.

These factors collectively contribute to the population homeostasis. A lower mortality rate coupled with a stable birth rate maintains a balanced population growth. Additionally, healthier individuals can interact more harmoniously with their environment, preserving resources more effectively for future generations.
