Please help!! Can you figure out the modern spreading rate of the Mid- Atlantic ridge? Use that line to figure out how many kilometers a plate moved from the spreading boundary in a set number of years. Convert that rate to the distance a point moves in just one year, rounding your answer to the nearest millimeter.
Answer:
R = 16mm/y
Explanation:
Modern Spreading Rate (R) = distance the seafloor moved in km (d) / age in million years (t)
R = d/t
To calculate it in millimeters per year we need to convert it:
1 km = 1000 m
1 m = 100 cm
1cm = 10mm
1 km = 1,000,000 mm
The problem states that in 150 million years, there is a distance of 2400 km.
if 1 km ------- 1,000,000 mm
2400 km-------X = 2400,000,000 mm
If 1 million years -------1,000,000 years
150 my----X = 150,000,000 years
R = d/t
R = 2400,000,000 mm/150,000,000 y.
R = 16mm/y

Why is active transport necessary for cells?
A. Diffusion is a very slow process.
B. Active transport is not necessary for all cells.
C. Sometimes molecules need to move from low to high concentrations.
Answer:
C. Sometimes molecules need to move from low to high concentrations.
Explanation:
Active transport is necessary for cells because sometimes molecules need to move from low to high concentrations.
Why is active transport necessary for cells?Active transport is very necessary for cells because this process enables cells to accumulate molecules or ions from the environment against the concentration gradient. The cellular membrane prevents large molecules from moving across freely, but there are still times when a cell needs to move substances in or out across the membrane. If the substance is moving down the concentration gradient the cell can use passive transport, but if it is moving against the gradient the cell must use active transport because it would require energy to do so.Conversely, the contents of cells heavily with electrolytes or metabolic products can be excreted against the concentration gradient.So, the correct answer is option C. sometimes molecules need to move from low to high concentrations.

The action that happens as a result of signals from sense organs processed by taking short- cut through a spinal cord?
Answer:
That's will be a Reflex Arc
Explanation:
A reflex arc is a neural pathway that controls a reflex. In vertebrates, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord. This allows for faster reflex actions to occur by activating spinal motor neurons without the delay of routing signals through the brain

Answer:
degradation option B
Explanation:
Degradation is the change from a higher or regular quality to a lower quality.
The change from a higher to a lower level of quality as exemplified by the reduction in the quality of surface water is called degradation.
What is degradation?Degradation is the deleterious change in the chemical structure, physical properties or appearance of a material from natural or artificial exposure.
Degradation can also involve a reduction in the quality of a substance.

2. Trace a molecule of carbon dioxide from a muscle cell to the environment in a vertebrate of your
choice. (This is an anatomy and physiology question and should include all four types of respiration, both
the respiratory and circulatory systems, and a mention of diffusion where appropriate).
I will choose a frog.The CO2 molecule is produced in aerobic respiration as a product from decarboxylation(R-COOH--->CO2+R-H) in Kreb's cycle. The CO2 molcule will leave the mitochondria. CO2 from the will diffuse from the muscle cell to the capilaries. From the capilaries the molecule will go into a vein. It will brought to the right atrium by the inferior vena cava. During atrial systole the molecule will be pumped in the ventricle(frogs only have 1 ventricle). During ventricular systole the molecule will be pumped into the pulmonary artery into the lungs where it'll diffuse out of the capilaries into the lungs and will be expired.
Describe how a renewable resource could become a nonrenewable resource
Answer:
Renewable resources can become nonrenewable resources if they are used faster than they can be replenished. If the resource no longer exists, there is nothing to regenerate or be replenished. For example, if we cut down trees faster than we grow them, trees can become a nonrenewable resource because there are no trees to regenerate.

How can genetic engineering be used to solve major worldwide dietary deficiencies such as vitamin and mineral deficiencies? (Igcse)
Genetic engineering offers promising solutions to combat major worldwide dietary deficiencies. By introducing specific genes into crops, we can enhance their nutritional content through biofortification, increasing essential vitamins and minerals like vitamin A, iron, zinc, and calcium.
Genetic engineering can improve protein quality and reduce anti-nutrients, making nutrients more accessible for absorption. Removing allergens from crops can also enable allergy-prone individuals to consume nutritious foods safely.
However, safety, ethics, and regulatory considerations are paramount. Public acceptance, thorough risk assessment, and adherence to ethical guidelines are vital to ensure the responsible and successful use of genetic engineering in addressing global dietary deficiencies.
