what is hypothesized to have caused the early primitive oceans to form our planet
Answer:
Explanation:
The primitive oceans formed from volcanoes at the beginning of time. When they blew up they released water vapour into the air. As the earth's crust cooled down, the water vapour condensed forming clouds, and water. The water fell as rain, which went down into the basins forming oceans. Scientists think they formed 4 billion years ago.

How does water use affect land ?
Answer:
All land uses have an effect on water quality, whether positive or negative. ... In built-up areas with pavement and buildings, little rainfall soaks into the soil, causing high runoff, stream flows with high peaks and low flows in between, and poorer water quality.
Explanation:
Hope this helped! Have an AMAZING day/night!!
Answer:
Surface-Water Contamination and Land Use A variety of natural and human factors can affect the quality and use of streams, lakes, and rivers, known as surface water. One of the most important factors that can affect the quality of a surface-water body is the land use within its watershed.

When organisms break the bonds of organic compounds, the organisms can ____. A. use the smaller molecules to plug the gaps in the cell membrane to slow diffusion B. use the energy obtained to digest molecules produced by respiration that uses oxygen C. obtain energy or reassemble the resulting materials to form different compounds D. excrete smaller amounts of solid waste materials during vigorous exercise
Answer:
C. obtain energy or reassemble the resulting materials to form different compounds
Explanation:
Organisms can break down organic bonds (usually C-C bonds) to produce chemical energy, especially in the form of Adenosine triphosphate (ATP). In living cells, ATP is considered to be the 'cell's energy currency' because this molecule provides energy for diverse cellular processes. Moreover, small organic molecules generated by chemical breakdown can also be reutilized in metabolic pathways in order to synthesize new (more complex) macromolecules. For example, fatty acids generated by the breakdown of longer lipidic macromolecules can be reutilized in different metabolic pathways to produce structural building blocks of the cell.
When a gummy bear shrinks, is that considered hypertonic or hypotonic?
Answer:
Hypertonic
Explanation:
In hyper-tonic solutions, the cell will shrink and crenate. The mass and volume of a gummy bear that is placed in a salt solution will decrease due to the effect of osmosis. When placed in water, a hypo-tonic solution, the gummy bear will expand in size and volume due to the water entering it.

The genetic material is arranged differently in the cell of bacteria compared with animal and plant cells.
Describe two differences.
Answer:
unlike bacteria cells, plant and animal cells both have membrane. Bacteria cells lack membrane. Bacteria multiple by binary fission.
Animal and plant cells contain linear chromosomes. Bacteria have one circular chromosone and no nucleus. Plasmids carry genetic material in some bacteria.
What is bacteria?Bacteria are unicellular organisms that are very tiny. Bacteria can be found practically anywhere on Earth and play an essential role in the ecosystems that exist there. Some animals are able to survive in environments with both high temperatures and high pressures.
Both plant and animal cells store their genetic material in the form of chromosomes, which are linear structures. Bacteria do not possess a truly organized nucleus and instead contain a single chromosone that is round. Plasmids are tiny circular pieces of genetic material that can be carried by some bacteria. These plasmids carry additional genetic material.

Donna has observed that her father can control the speed of their grandfather clock by adjusting
the height of the weight on the end of the pendulum. Donna thinks that the pendulum will move
faster when the weight is lowered, and wants to test her idea. Donna gets a stopwatch and
measures the time it takes for the pendulum to swing twenty times when the weight is moved to
its lowest position. Donna begins to move the pendulum up by 1 cm and continues to measure
the time for twenty swings of the pendulum. Donna records her data.
What is would the hypothesis be, Independent/dependent variable, the constants and the control group of this experiment?
Thanks!
Answer:
Hypothesis: IF the weight is lowered, THEN the pendulum will move faster
Independent variable: Weight on the end of pendulum
Dependent variable: Speed of the pendulum
Constant: Same pendulum, same stopwatch
Control group: when the weight is moved to its lowest position.
Explanation:
- Hypothesis is a testable explanation given to proffer solution to an observed problem or answer a scientific question. In this investigation, Donna thinks that the pendulum will move faster when the weight is lowered. Hence, Donna's hypothesis is IF the weight is lowered, THEN the pendulum will move faster.
- Independent variable is the variable that is changed or manipulated in an experiment. In this experiment, WEIGHT on the end of pendulum is the independent variable.
- Dependent variable is the variable that is measured or recorded in an experiment. In this case, the dependent variable is the SPEED of the pendulum.
- Constant is the variable that is kept unchanged for all groups throughout the experiment. In this experiment, the constants are Same pendulum used, same stopwatch
- Control group is the group that doesn't receive the experimental treatment in an experiment. In this case, the control is when the weight is moved to its lowest position.

O A.
True
OB.
False
Answer:
True, this is because they are used to keep balance and hold your own body weight, your wrist and hand shouldn't, that is why your arms and legs are for lifting heavy stuff. So that is why your tarsus and foot are stronger.

The main function of the rough endoplasmic reticulum is the production of Q
1. mitochondria and proteins secreted by the cell.
2. hydrogen peroxide and steroid hormones secreted by the cell.
3. ribosomes and steroid hormones.
4. membrane and proteins secreted by the cell.
Answer:
4. Membrane and proteins secreted by the cell
Explanation:
Endoplasmic reticulum (ER) is one of the organelle that makes up the endomembrane system of eukaryotes. The ER is of two types viz: rough endoplasmic reticulum (RER) and smooth endoplasmic reticulum (SER).
The RER is called "rough" because of the ribosome organelles that are attached to its surface. The attachment of this ribosomes (site of protein synthesis) also defines its function. The RER is principally involved in the production of protein. Hence, the Rough Endoplasmic Reticulum functions mainly in the production of membrane and proteins secreted by the cell.
The main function of the RER is the production of membrane and secretory proteins. Option D is correct.
Rough endoplasmic reticulum (RER) :
It is a membranous organelle that is a part endo-membrane system in the cell.
The ribosomes are attached to the RER, that make its appearance rough. Protein produced by the ribosomes is transferred to the RER lumen. Then it is modified and secreted.Therefore, the main function of the RER is the production of membrane and secretory proteins.

Each strand of s DNA molecule contains nitrogenous bases that pair with other nitrogenous bases in very specific ways. A diagram of a section of DNA is shown. DNDA Strand 3' _|___|___|___|___|___|___|___|___|___|___|___|___|_ 5' T G T A G C T G C G C G T Which DNA strand is complementary to the one shown above?
Answer:
The complementary DNA strand, according to the nucleotide sequence of the other strand is 3' - A C A T C G A C G C G C A - 5'
Explanation:
Each strand of DNA is made up of specific sequences of the four nucleotides present in this molecule, adenine, thymine, cytosine and guanine.
In double-stranded DNA, one strand complements the other —according to the complementarity of nitrogenous bases— where a purine, adenine and guanine, are joined with a pyrimidine, thymine and cytosine, respectively:
Adenine is complemented with Thymine. Guanine is complemented with Cytosine.According to this, the complementarity of the strands is:
5' - T G T A G C T G C G C G T - 3'
3' - A C A T C G A C G C G C A - 5'
The DNA strands remain linked by hydrogen bonds between their nitrogenous bases, until such time as they must be separated for transcription.
