write the function of these in your body. carbohydrates, protein, vitamin
Answer:
Carbohydrates- is the main source of energy of your body. They help you fuel your brain, kidneys, heart muscles, and central nervous system.
Protein- A lot of your body is protein. Your muscles are just about all protein, and most of your organs are protein. Many of the chemical reactions in your body are speeded up by other types of protein. Your body can make some of the components of protein by itself, and it must get some of the components from outside of the body.
You need protein daily for your tissue to repair itself, normal function, and perhaps to grow.
Vitamin- Vitamins allow your body to grow and develop. They also play important roles in bodily functions such as metabolism, immunity and digestion.

Explain why is it important to investigate water retention properties of soils
Answer:
Soil water can affect the structural integrity or coherence of a soil; saturated soils can become unstable and result in structural failure and mass movement. Soil water, its changes over time and management are of interest to geo-technicians and soil conservationists with an interest in maintaining soil stability.

Why are crystals in minerals formed from magma larger than mineral crystals formed from lava?
Answer:
Magma cools slowly inside Earth, which gives mineral crystals time to grow large enough to be seen clearly. Lava cools much more rapidly than magma when it is below the surface. In a cooling lava, mineral crystals do not have time to form and are very small.
compare the plants that live in deserts with the plants that live in the tundra biome.
Answer:
Both desert and tundra plants grow and flower quickly in the short growing season.
Desert plants have special structures that allow them to trap and store water.
Tundra plants grow low to the ground to stay out of the cold and dry wind.
Plants in the desert and tundra both develop and bloom swiftly. Plants in the desert have unique that enable them to capture and store water. To avoid the cold, dry wind, tundra plants grow low to the earth.
What is in the tundra biome?Tundra is the coldest biome of all of them. The Finnish name for tundra is tunturi, which meaning treeless plain. It is well known for having landscapes that have been formed by frost, very cold temperatures, little precipitation, insufficient nutrients, and short growth seasons. A dead organic substance acts as a source of nutrients.
What are the characteristics of the tundra biome?Tundra habitats, which are defined by their lack of plants and severe environments with minimal rainfall, are found in the Arctic and on mountain summits. The majority of the year, tundra areas are covered in snow, but the summer brings bursts of wildflowers.

Describe a freshwater biome.
Define a wetland.
Why do wetlands have high biodiversity?
A developer wants to extend a golf course into a wetland. Outline environmental arguments you could make against this plan.
Freshwater biomes are large communities of plants and animals centered around waters with less than 1% salt concentration. They are very important to survival on Earth. Types of freshwater biomes include ponds, lakes, streams, rivers, and even some wetlands. Wetlands are not always considered freshwater biomes because they usually have too high of a salt content.
2.
Wetlands are areas where water covers the soil, or is present either at or near the surface of the soil all year or for varying periods of time during the year.
3.
Wetlands have been called “biological super systems” because they produce great volumes of food that support a remarkable level of biodiversity. In terms of number and variety of species supported, they are as rich as rainforests and coral reefs.

how does the flow rate through capillaries affect the gas exchange rate between the blood in capillaries and interstitial fluid?
Answer:
the gas starts to bow
Explanation:
The flow rate through capillaries affect the gas exchange rate between the blood in capillaries and interstitial fluid by gas starts to blow.
What is interstitial fluid?In terms of nutrition, interstitial fluid serves as a sort of refueling station for our cells. Salt, fatty acids, glucose, and minerals like calcium, magnesium, and potassium are all present in interstitial fluid.
Blood capillaries are where the nutrients in interstitial fluid are obtained. Additionally, metabolic waste products can be stored in interstitial fluid.
A continuous glucose monitor will use a formula to offer a near estimate of what our blood glucose level is likely to be at that particular moment because the glucose level in interstitial fluid is not exactly the same as that in our blood.
Therefore, The flow rate through capillaries affect the gas exchange rate between the blood in capillaries and interstitial fluid by gas starts to blow.

will you be able to synthesize both strand of the dna helix in a continuous manner?
Answer:
No.
Explanation:
There are two strands in DNA -i)Leading strand
ii)lagging strand.
Replication of the leading DNA strand is continuous, while replication along the lagging strand is discontinuous. After a short length of the DNA has been unwound, synthesis must proceed in the 5' to 3' direction; that is, in the direction opposite that of the unwinding.
No, we will not be able to synthesize both strand of the dna helix in a continuous manner because the lagging strand synthesize in a discontinuous manner.
What is the process of DNA synthesize?The biological process of creating two identical copies of DNA from a single original DNA molecule is known as DNA replication. All living things replicate their DNA, which is the most crucial component of biological inheritance.
Continuous DNA synthesis takes place on the leading strand. As the helix unwinds, DNA synthesis on the lagging strand restarts numerous times, resulting in numerous brief pieces known as "Okazaki fragments," which are then joined by DNA ligase to form a single DNA molecule.

1. how would dr.budai refer to the new fern that contractors plan on introducing into the environment?
2.how might removing the flowering plants and replace it them with ferns affect the population numbers of the butterfly and the new species?
3. how might the building of the hotel affect the population of the new species?
Growing of ferns instead of flowering plants and building a hotel adversely affect the butterfly and species.
Dr. budai has bad reaction to the new fern that contractors plan on introducing into the environment because it will be grown instead of flowering plants which is necessary for the survival of butterfly.
Removing the flowering plants and replace it them with ferns negatively affect the population of the butterfly and the new species because butterfly feeds on the nectar of the flowers whose removal decrease the population of butterfly and those species which feed on butterfly also adversely affected due to unavailability of food source.
The building of the hotel adversely affect the population of the new species because habitat of that species will be destroyed so we can conclude that growing of ferns instead of flowering plants and building a hotel adversely affect the butterfly and species.
