what is the weight in mars
Answer:
Being that it takes the weight of an object on earth and converts it to Martian weight, the formula is Weight on Mars= (Weight on Earth/9.81m/s2) * 3.711m/s2. To find the Martian weight, we divide the weight on earth by the earth's force of gravity, which is 9.81m/s2. This calculates the mass of the object.

in the lung model how does the air move and out of the smaller balloons
Answer:
The plastic at the bottom of the balloons act like diaphragm , as it expands air move in throw the straw which represent trachea and when it contract, the air move out the balloons.
Explanation:
In the lung ballin model, the plastic at the bottom acts as the diaphragm. Diaphragm is a strong muscle that expand and contracts that cause air to flow in and out of the lungs. The movement of the balloon matches with breathing. When someone breathe in, air moves into the lungs like the balloons and it is because the diaphragm/plastic expands and these make air to enter through the straw which represent trachea and when you breathe out, the diaphragm contracts which allow air to move out.

Which statement best describes the role of DNA?
Answer: It transmits genetic information to the next generation
Explanation:
DNA stores information on how the cell should be made and ‘run’. This is why it is critical that its integrity is well preserved. Otherwise, mutations on DNA can be lethal to the cell. In higher cells, DNA is protected in the nucleolus. To pass down the genetic information, DNA is replicated by DNA polymerases and then during cell division, either copy of the pair goes to each of the two daughter cells.
Answer:
it contains genetic information
DNA strands are organized into small units which are known as genes. Genes carries sequences of bases which instruct the cells which protein is to be synthesized for a particular function in the body.

light provides the energy to power to what
Answer:
The sun's light (and all light) contains energy. Usually, when light hits an object the energy turns into heat, like the warmth you feel while sitting in the sun. But when light hits certain materials the energy turns into an electrical current instead, which we can then harness for power.

look at the SIMULATION pane. Is the displayed segment a part of a DNA or RNA molecule? how do you know?
Answer:
DNA
Explanation:
I did the assignment. and got a 100
The displayed segment is a part of a DNA MOLECULE. This nucleic acid (DNA) forms a double helix.
The deoxyribonucleic acid (DNA) is a double helix molecule composed of two long chains of nucleotides, which interact by hydrogen bonds.
Conversely, the ribonucleic acid (RNA) molecule is a single-stranded molecule consisting of a long chain of nucleotides.
In DNA, there are four types of nucleotides, each containing one distinct nitrogenous base, i.e., Adenine, Guanine, Cytosine and Thymine.
According to the base pair rules, Adenine always pairs with Thymine via two hydrogen bonds, whereas Guanine pairs with Cytosine through three hydrogen bonds.
In RNA, Thymine bases are replaced by Uracil bases.

Why did removing bees have a bigger effect than removing the rabbits?
I think removing bees have a bigger effect than removing rabbits because bees help a lot with our earth and some things would probably be bad without them. Bees do things like help plants grow, breed and produce food, and they transfer pollen between flowering plants so they can keep the cycle of life turning. Plus they make great honey ! But with the rabbits they can sometimes cause damage to the earth by overgrazing native and sown pastures, leading to loss of plant biodiversity and reduced crop yields. and they also compete with native animals and domestic livestock for food and shelter, increasing grazing pressure and lowering the land's carrying capacity. So therefore, if we removed bees from our earth it would turn everything upside-down more then it would with rabbits. :)
A city spends $15 million on a beach nourishment project that adds 1.8 million cubic yards of sand to 3 miles of beach. What is the cost per cubic yard of sand?
Answer:
The answer is $8.33 per cubic yard.
Explanation:
This problem is just a normal math equation. You divide the price by how much space you are covering to get the smallest ratio(15 million divided by 1.8 million). After dividing you get the answer of $8.33 per cubic yard.

How do enzymes act as catalysts? (Choose ALL that apply) They allow for fewer collisions of molecules (enzymes + substrates) They allow for more collisions of molecules (enzymes + substrates) They raise the amount of activation energy needed to complete the reaction They lower the amount of activation energy needed to complete the reaction They speed up chemical reactions to form more products
Answer:
- They allow for more collisions of molecules (enzymes + substrates)
- They lower the amount of activation energy needed to complete the reaction.
- They speed up chemical reactions to form more products
Explanation:
Enzymes are proteinous molecules that serves as catalyst in living systems. Like every other catalyst, enzymes function to SPEED UP the rate of biochemical reactions by LOWERING/REDUCING the activation energy, which is the energy required for a reactant to form product (completion of reaction).
Enzymes like other catalysts causes faster movement of molecules in the reaction i.e. they allow for more collisions of molecules (enzymes + substrates). This causes the rate of reaction to increase and hence, speeden the reaction.
Answer:
they lower the activation energy

8. Alexander was studying the effect of playing rock music on plant growth.
One of the plants was exposed to rock music for 24 hours a day for a
period of 6 weeks. Data on the growth of the plant was collected at
the end of each week and plotted in a graph. Based on the data,
which would be the MOST reasonable measurement at the end of an
8-week period?
A. 2 decimeters B. 6 decimeters
C. 8 decimeters D. 16 decimeters
Answer:
C. 8 decimeters
Explanation:
As seen on the graph, the height of the plant is located on the y-axis while the period of growth or time in weeks is located on the x-axis. If you observe closely, the plant has an average growth of 1 decimeter per week.
week 1 = 1 decimeter
week 2 = 2 decimeters
week 3 = 3 decimeters
week 4 = 4 decimeters
week 5 = 5 decimeters
week 6 = 6 decimeters
week 7 = 7 decimeters
So, this means that at the end of the 8-week period, the plant's height is at 8 decimeters.

What is logistics growth curve?
The logistics growth curve is defined as the population per capita growth rate is decreases and get smaller and the size of population increases maximum applied by resources which are limited in the environment which is known as the K that is carrying capacity.
The logistics population growth is represented by logistic growth curve on a line graph and the shape of curve is S - shaped that represents slow increase, and rapid growth in population and after that there is reduction in growth.
The best example of logistics growth is observed in wild population that includes sheep as well as harbor seals. In both of the cases the number of population increases and carrying capacity for small period of time.
Therefore, A person with a degree in economics and an emphasis in agriculture would best be able to perform the jobs of human resources professional. Thus, option A is correct.

2. DNA-DNA contains the instructions needed for an organism to develop, survive and reproduce.
3. DNA with a mutation- Mutations range in size; they can affect anywhere from a single DNA building block (base pair) to a large segment of a chromosome that includes multiple genes.
4. Nucleus- The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information.
5. Organism- Organisms respond to stimuli from their environment and actively maintain their internal environment through homeostasis.
6. Proteins- Your body uses protein to build and repair tissues.
7. Ribosome- Within the ribosome, the rRNA molecules direct the catalytic steps of protein synthesis — the stitching together of amino acids to make a protein molecule.
8. Amino acid - When you eat protein, your body breaks the protein down into amino acids. Those amino acids are then used to repair and grow new muscle fibers. When you consume an adequate amount of protein, your body will experience something called a positive balance of nitrogen.
