Answer:
Population is growing rapidly, far outpacing the ability of our planet to support it, given current practices. Overpopulation is associated with negative environmental and economic outcomes ranging from the impacts of over-farming, deforestation, and water pollution to eutrophication and global warming.

What do members of a population have in common? Select all that apply.
A. They live in the same area.
B. They have the same density
D
C. They are the same species.
D. They live at the same time.
E. They are the same size
Answer:
the answers are a, c, and d
Explanation:
a makes sense because if you are a member of a population then the other members live in the same area as you
b doesn't make sense because even though you live in the same population as someone, it doesn't mean you'd have the same density
c makes sense because the definition of population is, "a group of individuals of the same species living and interbreeding within a given area."
d makes sense since in order to be considered a member of a population you have to be living
e doesn't make sense since everyone is a different size
Members of a population have in common -
A. They live in the same area.
C. They are the same species.
D. They live at the same time.
A population is defined as a group of individuals of the same species living and interbreeding within a given area.

which bone layer holds calcium and other minerals
Answer:
In addition to its mechanical functions, the bone is a reservoir for minerals (a "metabolic" function). The bone stores 99% of the body's calcium and 85% of the phosphorus. It is very important to keep the blood level of calcium within a narrow range. If blood calcium gets too high or too low, the muscles and nerves will not function. In times of need, for example, during pregnancy, calcium can be removed from the bones. This process is carefully regulated by hormones and is discussed more completely in the section about hormones.

Answer:
its the um (dont quote me ) phophorus im pretty sure
Explanation:
During physical activity metabolism speeds up and muscles require more oxygen and nutrients. How does the heart keep up with this demand? Choose all that apply.
The heart goes in tachycardia mode to deliver more oxygen to the muscles.
The heart beat has a steadily constant beat of 60 beats per minute.
The heart pumps faster (increased heart rate) and stronger (increased stroke volume).
An increased cardiac output helps deliver more nutrients and oxygen to the working muscles.
The lungs are the organs bringing oxygen to the muscles, the heart is not involved.

Which explanation below is the most accurate regarding animal and plant adaptations for survival in a desert biome
Answer:
i think its C sorry if I'm wrong
Explanation:
The most accurate regarding animal and plant adaptations for survival in a desert biome is
Animals in this biome tend to have scaly skin to save water and stay cool; plants have thick roots that capture water.
What is the desert biome?Deserts are extremely dry environments that support a diverse range of plants and animals. Deserts are classified into four types: hot and dry deserts, semi-arid deserts, coastal deserts, and cold deserts.Plants adaptationPlants in the desert are succulent, storing water in fleshy leaves, stems, or roots. Water absorption is well developed in the root system. The stem in these pants also performs photosynthesis. Their stems and leaves have a thick cuticle that protects them from excessive transpiration. To avoid excessive water loss, desert plants use the CAM pathway.Animals adaptationAnimals in the desert exhibit a variety of adaptations. Snakes, for example, come out in the open only at dawn or dusk. To avoid the heat, some small desert animals live in burrows.Camels, for example, store fat in their hump. This allows them to go a long time without food or water.Thus, we can conclude that Animals in this biome tend to have scaly skin to save water and stay cool; plants have thick roots that capture water. which is option C.

The pH of a solution determines the charge of certain R groups. The pH of pineapple fruit ranges from 3.5 to 5.2. Predict the effect on the activity of bromelain if it is used in a product with a pH of 11.
Answer:
The activity of Bromine will reduce
Explanation:
Bromine is found in pineapple stem with pH range of 3.5- 5.2 this implies that the environment where bromine is found is acidic hence when taken to a product whose pH is 11 which is basic then its performance will be low because its can only function well in an acidic medium.
pH ranges tell whether a substance is acidic, basic or neural.
Acid range from 3.5-6
7- neutral
8 above is basic
This is about knowing the behaviour of some elements in different PH Values.
The activity of bromelain will decrease in a product with a pH of 11. .
We are told that the PH of pineapple fruit is of the range of 3.5 - 5.2. In reality, this also includes it's stems and the plants as well. This falls into the acidic range because PH less than 7 is acidic.Now, these stems, plants and fruits of pineapple usually contain bromelain. This implies that bromelain does its' work in an acidic environment since pineapple has an acidic PH.If bromelain is used in a product with a PH of 11, it means it is being used in a basic environment because a PH greater than 7 indicates a basic nature. This means bromelain will not function as well as it did in the acidic environment and as such the activity of bromelain here would decrease.We can now conclude that the activity of bromelain will decrease in a product that has a PH of 11.

.it can be replanted after it is cut down
resource A is most likely an.
A. inexhaustible resource
B. nonrenewable resource
C. recycled material
D. renewable resource
Answer:
Option D, renewable resource
Explanation:
A renewable resource is the resource which can be replenished after every use. Or in general the time taken by it to replenish must be small. For instance, fossil fuels too are renewable but the time taken by them to renew is too high and hence they are also considered as non-renewable.
Also renewable resources can be used again and again.
Hence, option D is correct

Provide a summary of biologist Stephen Stearns’ findings in how Natural Selection may be working today in humans.
Answer:
Stephen Stearns states that natural selection doesn't mean the survival of the fittest organisms, but rather this mechanism is illustrated by the selective reproduction of the fittest. Natural selection can be classified into distinct types, including directional, disruptive and stabilizing selection, which are in turn based on sexual selection. These types of selection are driven by different outcomes that have different dynamics.
