Are the anomalies the same thickness along all ridge segments Why or why not?
plz help :D

Answers

Answer:

The equivalent magnetization (EM) and mantle Bouguer anomaly (MBA) were calculated along the ultraslow-spreading Mohns Ridge axis in the Norwegian-Greenland Sea. The magnetic anomaly and the associated EM were compared with the bathymetry, MBA, seismically determined crustal structure and geochemical data at both the inter-segment scale (>60 km) and the intra-segment scale (20–60 km). At the inter-segment scale, the magnetic highs at the segment centers are independent of the MBA. Of the 13 segments, 9 with magnetic anomalies >700 nT coincide with axial volcanic ridges identified from multibeam bathymetry maps, which suggests that the magnetic highs at the segment centers may be more associated with the extrusive lavas rather than the amount of magma supply. With few exceptions, the magnetic anomaly lows associated with MBA highs at the segment ends increase from south to north. This trend might be explained by thickened extrusive basalts and/or more serpentinized peridotites at the segment ends in the north. At the intra-segment scale, the most prominent features are the decreases in the magnetic anomalies and associated EMs from the segment centers to the ends. The intra-segment magnetic anomalies have positive and negative correlations with the bathymetry and MBA, respectively. The magnetic signal modeled by the seismically determined layer 2A with an assumed constant magnetization is remarkably consistent with the observed magnetic anomaly, which strongly suggests that the thickness of the extrusive basalts dominates the magnetic structure in each segment along the Mohns Ridge. In general, the thickness of the extrusive basalts dominates the magnetic structure along the Mohns Ridge, whereas the contributions from serpentinized peridotites may be significant at the segment ends and may produce long-wavelength magnetic variations. The magnetic data can be used as an indicator of the thickness of the extrusive basalts within segments along the ultraslow-spreading Mohns Ridge.

Remember that we see the color of objects because that color bounces off the object and back to our eyes. The other colors are soaked up by the shirt like a sponge. Why do you think the green light is the least effective color to give plants energy to grow?

Answers

If the light color is red or purple then the plant will absorb some amount of energy from the light, Green light is the least effective for plants as the plants are themselves green due to the presence pigment Chlorophyll in chloroplast.

what is function of chloroplast ?

Chloroplasts are the membrane bound cellular organelle present in photosynthetic organism like plants and algae, observed in  mesophyll cells of leaves and contain a high concentration of chlorophyll pigment which absorb sunlight.

It has extra-nuclear semiautonomous DNA and make food by the process of photosynthesis by absorbing sunlight into chemical energy.

It also involve indirectly  in the process of generation of carbon and sugar molecule during the Calvin Cycle or dark reaction of photosynthesis.

Chlorophyll absorbs energy from blue- and red-light waves and reflects green-light waves during photosynthesis, giving the plant its characteristic green color.

What is the effect of green light in plants?

Other pigments, such phycoerythrin, can effectively absorb green light to promote photosynthesis. Additionally, green light can encourage stem elongation, which boosts plant light absorption.

Despite being the visible spectrum's least effective wavelength for photosynthesis, green light is nonetheless helpful and affects plant morphology.

One might occasionally hear that plants reflect green light rather than using it for photosynthesis.

Therefore, green light is the least effective color to give plants energy to grow.

What is photosynthesis?

It is defined as a process by which plants and other photosynthetic organisms convert the light energy in to chemical energy through the process of cellular respiration.

Some of the energy which is converted  is stored in molecules of carbohydrates like sugar and starches  which are made up of from carbon dioxide and water . Photosynthetic organisms which can perform photosynthesis  are algae and cyanobacteria. Photosynthesis is largely responsible for producing and maintaining the content of oxygen in earth's atmosphere.

The process begins with proteins absorbing light energy  which are called reaction centers and contain a green pigment which is called chlorophyll . In plants ,these pigments are present inside organelles called chloroplasts while in bacteria they are present in plasma membrane.

g When an oxygen molecule diffuses from the air in the lung into the plasma in a capillary in the lung, how many times does it have to diffuse through a plasma membrane before reaching the plasma

Answers

Answer:

The answer is 2.

Explanation:

When oxygen gets into the lungs, it first needs to diffuse through the alveoli and into the blood. Then through the veins and capillaries, it diffuses into all the calls in the body. It does so quite easily because it is a nonpolar and a very small molecule with a low concentration inside the cell. This gives it the ability to diffuse easily through the cell membrane.

So the number of times that oxygen has to diffuse through a plasma membrane is two.

What is the role of ATP when large molecules need to be transported across the cell membrane against the concentration gradient?
The bond between the phosphate groups is broken to store energy.
The bond between the phosphate groups is broken to release energy.
Bonds are formed between the adenine and the ribose to store energy
Bonds are formed between the ribose and the phosphate to release energy.

Answers

Answer:

b. the bond between the phosphate groups is broken to release energy

Explanation:

Phosphate groups are negatively charged => there is a pull between the two groups

=> it's easy to break this bond & ATP is unstable

=> ATP has a lot of free energy

breaking the bond between phosphate groups makes the molecules more stable (aka contains less free energy)

=> delta G <0

=> breaking this bond releases energy

the energy released by ATP is then used to transport large molecules against the concentration gradient

The bond between the phosphate groups is broken to release energy. This energy helps in the transport of molecules across the cell membrane against the concentration gradient.

ATP is also called as the energy factory for the cell. It is also required for various metabolic processes within and outside the cell. It has a role in transfer of macromolecules like proteins, lipids, and other into and out of the cell. It is difficult for molecules to be transported into and out of the cell across a  cell membrane against a concentration gradient for this energy in the form of ATP is required. When the hydrolysis of the molecule of ATP occurs it releases the phosphate group along with the release of energy this energy is necessary for the active transport of molecules against the concentration gradient across a cell membrane. Hence, the bond between the phosphate groups is broken to release energy. This energy helps in the transport of molecules across the cell membrane against the concentration gradient.

what is the difference between natural selection and evolution

Answers

Answer:

Evolution is a gradual change in the inherited traits of a population over many generations.

Natural selection is a mechanism where the members of a population best suited to their environment have the best chance of surviving to pass on their genes. The natural environment selects for these members over others in the population.

Over many generations, because more of the best suited members have been reproducing, the population all now have the trait that makes them better suited for the environment.

This population has now evolved to better suit its environment, through the process of natural selection.

Organisms often mimic their surroundings to escape the predators. This technique is also called camouflaging.

Forest butterflies have also adopted several structural adaptations to avoid predators. Many of them have brown wings with jagged edges so that they resemble dried leaves. In this way, they blend with their surroundings, especially the forest floor, and go unnoticed. On the other hand, butterfly larvae are green in color so that they resemble the leaves on which they feed and avoid predators.

What is natural selection?

If a mutation occurred in a squirrel that caused it to have white fur, and if this trait helped the squirrel survive and reproduce more effectively in a cold, snowy environment, then it is possible that the trait could become more common in the population over time. This is known as natural selection.
