How does coral reef damage negatively affect the land? a.) There is more biodiversity. b.) There is a loss of cures. c.) There is more land erosion.
Answers
The answer would be C
Coral reef damage negatively affects the land primarily by causing a loss of cures. Hence the correct option is B.
1. Loss of cures: Coral reefs are incredibly diverse ecosystems that provide numerous ecological and economic benefits. One significant impact of coral reef damage is the loss of potential cures and medicinal resources. Many marine organisms, including those found in coral reefs, contain bioactive compounds that have the potential for developing new medicines, treatments, and therapies. By damaging coral reefs, we risk losing these valuable resources and potential cures for various diseases.
2. Biodiversity decline: While option A, "There is more biodiversity," is incorrect in this case, it is important to note that coral reefs are known as the "rainforests of the sea" due to their high biodiversity. Coral reefs support a wide range of marine species, providing habitats, shelter, and food sources. When coral reefs are damaged, either through human activities like pollution, overfishing, or climate change-related factors like coral bleaching, the biodiversity of the reef ecosystem decreases.
3. Land erosion: Option C, "There is more land erosion," is not typically a direct consequence of coral reef damage. However, healthy coral reefs do play a role in protecting the coastline from erosion. Coral reefs act as natural barriers that help dissipate the energy of waves, reducing wave-induced erosion and protecting nearby coastlines from storms and wave action. When coral reefs are damaged or destroyed, the protective function of the reef is lost, potentially leading to increased erosion of the nearby land.
Hence the correct option is B

Which of the following is true of red blood cells? A. They live for only 120 days. B. They have multiple Nuclei. C. They live for only about 20 days. D. Once created in bone marrow, they circulate for our lifetime.
Answers
A. They live for only 120 days is correct. They are created in the bone marrow and destroyed in the spleen "red blood cells graveyard"
B. They have multiple Nuclei. Red blood cells don't have a nucleus but some can present structures called Jolly's bodies that are small pieces of the nucleus that they lost in the differentiation process
C. They only live for only about 20 days. No, red blood cells live for about 120 days
D. Once created in bone marrow, they circulate for our lifetime. Again, they have a limited lifetime

Answer:
Explanation:
We present an explicit and simple approximation for the superadiabatic excess (over ideal gas) free power functional, admitting the study of the nonequilibrium dynamics of overdamped Brownian many-body systems. The functional depends on the local velocity gradient and is systematically obtained from treating the microscopic stress distribution as a conjugate field. The resulting superadiabatic forces are beyond dynamical density functional theory and are of a viscous nature. Their high accuracy is demonstrated by comparison to simulation results.
Answer:

Which is not a benefit of maintaining sustainable forest ecosystems?
Select one:
O a. Empty space on which to build homes
b. Habitat for thousands of species
c. Reduction of erosion in watersheds
Answers
The correct answer as to which is not a benefit of maintaining sustainable forest ecosystems would be empty spaces on which to build homes.
An ecosystem refers to a network of communities interacting together as a unit. A forest ecosystem, therefore, is a community of different plants, animals, and microbes interacting together and with their physical environment as a unit.Sustainable forest ecosystem is a system of managing forest resources in such a way that the ecological processes and functions provided by the forest do not depreciate. The ecological functions of forest ecosystems include the provision of foods, drugs, and raw materials for man, protection of watersheds, provision of habitats for other species, and playing important roles in the stability of climates.Hence, not maintaining forest ecosystems in a sustainable way means that some of the functions they perform such as the provision of habitats for species and reduction of erosion in watersheds would be lost.
The only option that is not a benefit of maintaining sustainable forest ecosystems is A.

juan earn $11 per hour and works at most 30 hours per week. identify the independent and dependent quantity in the situation, and find reasonable domain and range values

Answer:
The hours are the independent variable.The wages/wk earned are ( $11/hr )x( hrs worked ) . This is the dependent variable ( depends on hours worked ) .The domain is 0 to 30 The range is 0 to 330Explanation:
The hours are the independent variable and should be plotted on the x-axis .
The wages/wk earned are ( $11/hr )x( hrs worked ) . This is the dependent variable ( depends on hours worked ) and should be plotted on the y-axis

Let +W+ = wages/wk earned
Let +h+ = hours/wk worked
The equation is:
+W+=+11h+
The domain is 0 to 30
( no hrs worked to 30 hrs worked )
The range is 0 to 330
