which bone layer holds calcium and other minerals

Answers

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.

Which explanation below is the most accurate regarding animal and plant adaptations for survival in a desert biome

Answers

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.

What feature is the same in the formation of many sedimentary rocks and fossil fuel?many sedimentary rocks and fossil fuels-
A-require material to be buried and exposed to heat amd pressure.

B-are made out of organic material that stores the sun energy

C-form where there are frequent earthquakes and volcanic activity

D- are produced high in the mountains where temperatures are low

Answers

Answer:

maybe C i'm so sorry if this is wrong

Explanation:

Organic materials and silt build on top to produce fossil fuels. Heat and pressure transform organic materials into coal, petroleum, or natural gas. Therefore, option (A) is correct.

What are fossil fuels?

An extracted and burnt fossil fuel is a hydrocarbon-containing substance that naturally originated in the Earth's crust from the remnants of extinct plants and animals. Coal, oil, and natural gas are the three primary fossil fuels.

Because certain sedimentary rocks contain trapped fossil fuels, sedimentary rocks and fossil fuels are connected. As organic materials and silt build up on top over time, fossil fuels are created. The organic material undergoes a chemical shift under heat and pressure, turning it into coal, oil, or natural gas.

Provide a summary of biologist Stephen Stearns’ findings in how Natural Selection may be working today in humans.

Answers

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.

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.

Answers

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.
