27 cm
113 cm
Answers
Answer:
4780.3 cm^3
Explanation:
A cone is a three-dimensional shape and its volume can be calculated using the formula:
V = 1/3 πr^2h or πr^2h / 3
Where V= Volume of cone (cm^3)
r= radius (cm)
h= height (cm)
π= constant (22/7)
In this question, the values of r and h are 13cm and 27cm respectively.
Hence, to calculate the volume of the cone, we say;
V = 1/3 × 22/7 × 13 × 13 × 27
V = 100,386 / 21
V = 4780.2857142857
4780.285 to the nearest tenth is ~ 4780.3
Therefore, 4780.3cm^3 is the volume of the cone.

Answers
Answer:
He extracted and observed DNA from white blood cells.
Explanation:
Friedrich Miescher, who is a Swedish Botanist, is the scientist who isolated for the first time. In 1869, Miescher isolated a chemical he called NUCLEIN, which is called Nucleic acid now.
He discovered this so called "NUCLEIN" substance from the nuclei of white blood cells. Nucleic acids are the DNA and RNA we know today, hence, Miescher's discovery was significant to the genetic code as he even agitated for the inclusion of his discovery into inheritance.

succession?
Biodiversity increases through the process of succession.
Biodiversity decreases through the process of succession.
Biodiversity does not change during the process of
succession.
Answers
Answer:
It Increases.
Explanation:
Biodiversity is the the variety of living organisms such as wildlife and plants. The number of organisms and biomass amount further increases in the ecosystem in which the process of succession is occurring.
The numbers will stabilize when a climax stage has occurred in succession, which will not change the biodiversity.
The sort of many lives living together in an ecosystem or habitat is called biodiversity. Biodiversity increases during the process of succession.
What is succession?Succession is the biological and chemical process of change and formation of the habitat and species of a particular place during a period. It can be primary or secondary.
The formation of the new habitat in barren land is primary succession while the formation of the ecosystem in a once habituated place is secondary succession.
Biodiversity always increases in the succession process till the climax community is not achieved till the conditions are well balanced.
Therefore, option A. biodiversity increase in the process of succession.

Some plants and animals are capable of asexual reproduction. Describe how this process occurs in one specific plant and one specific animal. Discuss the benefits and pitfalls of this reproduction strategy for each organism. Conclude with an explanation of how asexual reproduction can help and hinder a population’s ability to grow.
Answers
Reproduction is the biological process by which new organisms known as the offsprings are produced by their parents. It is of two types: Sexual reproduction and Asexual reproduction. The difference between the two types lies in the number of parents required for both. In Sexual reproduction, two parents are required to give rise to the offspring. In asexual reproduction, a single parent can give rise to the offspring. Asexual reproduction is commonly seen in plants but is less common in the animal kingdom.
The advantages of sexual reproduction:
produces genetic variation in the offspring
the species can adapt to new environments due to variation, which gives them a survival advantage
a disease is less likely to affect all the individuals in a population
In asexual reproduction there is only one parent. The offspring are clones of the parent and each other.
The advantages of asexual reproduction include:
the population can increase rapidly when the conditions are favourable
only one parent is needed
it is more time and energy efficient as you don't need a mate
it is faster than sexual reproduction
The disadvantages of sexual reproduction:
time and energy are needed to find a mate
it is not possible for an isolated individual to reproduce
The disadvantages of asexual reproduction include:
CONCLUSION:
it does not lead to genetic variation in a population
the species may only be suited to one habitat
disease may affect all the individuals in a population.

Scientists have been studying threats to coral reefs. The percent of reefs affected by various threats are shown in the figure below. A future global temperature increase may affect all categories on the figure. Predict which category would change the most from global temperature increases and propose a testable question that scientists could study.
a. The biggest effect will be on the far right column that includes thermal stress with a greater percentage of reefs falling into the low and medium threat categories. Scientists could test whether reefs that have greater fishing risk also have greater thermal risk.
b. The biggest effect will be on the far right column that includes thermal stress, with a greater percentage of reefs falling into the high and very high threat categories. Scientists could test whether reefs that have greater temperature changes have greater increases in watershed-based pollution.
c. The biggest effect will be on the far left column that includes fishing, with a greater percentage of reefs falling into the high and very high threat categories. Scientists could test whether increased fishing causes increased marine-based pollution.
d. The biggest effect will be on the far left column that includes fishing, with a greater percentage of reefs falling into the low and medium threat categories. Scientists could test whether reefs that have greater temperature changes have greater increases in fishing threats.
Answers
Answer:
It's B
Explanation:
Temperature rise will eventually end up putting coral reefs into the high threat categories, not fishing and DEFFINITELY not lowering their "risk" factor.
Coral reefs are the organisms of the aquatic ecosystem. The column includes the thermal stress that will be affected the most as the reefs fall into high and very high threats are huge. Thus, option B is correct.
What is the effect of thermal stress on coral reefs?Due to an increase in pollution and global warming, the oceans have heated up, which results in thermal stress and leads to coral bleaching and threat to the coral reefs.
The percentage of the very highly threatened, highly threatened, slightly threatened, and threatened reefs are seen majorly due to the thermal stress. Thermal stress is in increases amount due to oceanic warm-ups.
The thermal stress due to increased carbon dioxide activities and acidity leads to coral bleaching causes the destruction of the reefs and their endangerment.
Therefore, option B. the far right column labeled thermal stress has the biggest effect on the coral reefs.
