When looking at graphs showing 800,000 years of past climate data, there is a direct relationship over time between temperature and the concentration of carbon dioxide in the Earth's atmosphere is a <u>true</u> statement.
Explanation:
Many paleoclimate studies and research done by observing events like glacial cycles etc over the past 800,000 years about climate changes over the past years have proved the strong linear relationship between temperature and carbon dioxide concentration in the Earth’s atmosphere.
These studies clearly reiterate that when the carbon dioxide concentration in the atmosphere increases, the temperature also increases; and when the CO2 concentration decreases, the temperature also decreases. Carbon dioxide also controls the amount of greenhouse gases in the atmosphere by controlling the temperature.
Increased CO2 levels increases temperature which in turn will increase the evaporation of greenhouses gases present in the atmosphere including CO2 from the reservoir; however, the CO2 can stay in the atmosphere for very long time. All of these factors have led to various climate changes globally

Answer:
B. The horse and donkey are not members of the same species because their offspring are sterile.
Explanation:
The horse and donkey aren't members of the same species since the donkey has 62 chromosomes while the horse had 64 chromosomes and members of the same species need to have the same number of chromosomes. This leads to the mule having 63 chromosomes which is an odd number of chromosomes so it is sterile.

You are actually correct it is D
Answer:
One advantage of sexual reproduction over asexual reproduction is , sexual reproduction provides genetic diversity.
Explanation:
- Asexual reproduction is the type of reproduction which does not involve the formation or fusion of Gametes.
- Since no fusion of gametes takes place, traits do not combine and no genetic variation results.
- Sexual reproduction involves the production and fusion of male and female gamete.
- Since the participating gametes come from different individuals, their traits combine are present in the offspring.
- Sexual reproduction causes genetic variation and development of new characters in the offsprings.
- This leads tp genetic diversity in the population.
