Which of the following is the best statement comparing the water of today with the water
that was here 100 million years ago? (1 point)
A) Water enters and leaves Earth duing evaporation and precipitation cycles.
B) The water present on Earth today is made of the same atoms but the molecules
have been recycled through biologic activity.
C)The atoms that made the water then were destroyed when they were used; the
atoms that make up water now were made more recently.
D)The molecules of water then are the same molecules that exist today.
Answer:
A. Water enters and leaves Earth during evaporation and precipitation cycles.
Explanation:
Answer:
B
Explanation:
C is wrong because, atoms cannot be destroyed or made according to the law of conservation of mass. D is wrong because water goes through many processes, like A states, but both are wrong because B is the most correct.
according to the hydrologic cycle, once precipitation has fallen on land, what paths might the water directly take?
Answer:
it either soaks into the ground, infiltration, flows over the surface as runoff, or immediately evaporates.

which mechanism of action is being described when an antibiotic drug causes the destruction of bacterial cell walls
The mechanism of action described when an antibiotic drug causes the destruction of bacterial cell walls is NONSELECTIVE INTERACTION. These drugs do not interact with specific molecules.
Nonselective drugs are involved in nonselective interactions, i.e., they act on a variety of receptors and/or enzymes.
Nonselective drugs can target different cellular structures (e.g., bacterial cell walls) and/or metabolic processes.
For example, Phenocybenzamine is a nonselective drug that can affect different receptors, which is used for the treatment of high blood pressure and sweating associated with pheochromocytoma.
Conversely, enzymes are biological catalysts that speed up chemical reactions by selectively interacting with specific ligands (i.e., substrates).

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.
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.
sorry last question i don't no
4. Which areas seem to be most highly and quickly affected by a continued increase in
carbon emissions?
Answer: The atmosphere will be hit hardest by the increase in carbon. As the amount of carbon increases, it leads to increased warming of the atmosphere. Rising temperatures also increase the rate of evaporation, creating a more humid atmosphere and creating a virtuous cycle of warming.
This increase is beneficial as the Earth freezes due to the absence of carbon dioxide and other greenhouse gases in the air.

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.

Answer:
It is dominant over "dwarf plant."
Explanation:
If a true-breeding tall pea plant is crossed with a true-breeding dwarf pea plant and all of the offspring are tall plants, the trait tall plant is it is dominant over "dwarf plant."
What is dominant traits?Dominant traits are always explained when the related allele has dominant, even if only one copy of the dominant trait exists. Recessive traits are expressed only if both the connected alleles are recessive.
The frequency of expression of dominant and recessive traits can be Dominant traits = always / Recessive = sometimes.
According to the question if there is self cross TT×tt then there is TT, Tt, Tt and tt, which means there is a 75% possibility of dominant trait and 25% recessive.
A dominant trait has an inherited trait or characteristic that appears in an offspring and covers the effects of another allele and/or prevails or exhibit its trait above another.
Therefore, If a true-breeding tall pea plant is crossed with a true-breeding dwarf pea plant and all of the offspring are tall plants, the trait tall plant is it is dominant over "dwarf plant."

The transcription factor that binds directly to the tata-box sequence is TFIID. This transcription factor (TFIID) is a macromolecular protein complex.
The TATA box is a fundamental nucleotide gene sequence that forms the eukaryotic core promoters, which are required to initiate transcription.
TFIID is a macromolecular protein complex (also called the RNA polymerase II preinitiation complex), which acts as a general transcription factor during the initiation of eukaryotic transcription.
TFIID recognizes and binds to the TATA box (core promoter) and also binds with different activator and repressor proteins in order to regulate the transcriptional activity.
