In a hostel, 30 students have food enough for 40 days. How many students should leave the hostel so that the food is enough for 100 days ?
Answer:
ffffffghjkoiuhbnm,,,,
Explanation:
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?
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.

#SPJ1
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.

5. If the weather in Richmond, Virginia, changed to very cold (snow on the ground 8 months of each year) over the next few years, what change might occur?
a. The cold weather would cause a mutation in squirrels which causes their fur to be white.
b. If a mutation occurred which caused white fur to develop, such white squirrels would have a better chance to survive and produce more offspring with the characteristic.
c. Evolution would definitely occur resulting in white squirrels.
Answer:
A.
Explanation:
Because, they would have to adapt to their surroundings to survive and the white fur is a little thicker and help them blend in better form predators
b. If a mutation occurred which caused white fur to develop, such white squirrels would have a better chance to survive and produce more offspring with the characteristic.
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.
However, it is important to note that whether or not a particular trait will become more common in a population depends on many factors, including the environment, the competition for resources, and the presence of predators.

Where homo erectus part of the neolithic revolution
In addition to having a more contemporary and body proportions, H. erectus was the first species of human to have a flat face, a prominent nose, and perhaps minimal body hair coverage.
Though there is little doubt that brain size has increased compared to ancestral species, capacity varies greatly depending on population. The size disparity between males and females in H. erectus may have been relatively small (i.e., there was less sexual dimorphism), which may have indicated monogamy in keeping with patterns seen in other primates. Although it is hypothesised that they interacted with one another using some form of proto-language, it is unknown whether H. erectus had the anatomical capacity for speech.
The Pleistocene archaic human species H. erectus, which means "upright man," first appeared about 2 million years ago. It is now extinct. Several human species, including H. heidelbergensis and H. antecessor, seem to have diverged from H. erectus, with the former being largely accepted as the ancestor of Neanderthals, Denisovans, and modern humans. Among the first recognisable representatives of the genus Homo are its specimens. The first known ancestor of modern humans, H. erectus, had a continental range that stretched from the Iberian Peninsula to Java.

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

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
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.
I hope this answer helps.

what is the difference between natural selection and evolution
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.

Answer:
guard cellsmonocots: evenly distributed, dicots: more dense on lower leaf Carbon dioxideExplanation:
Stomata are pores in the leaf surface of plants. they regulate the exchange of moisture and gases in plants. They open at night for the exchange absorption of Carbon dioxide and expulsion of Oxygen, while closing at the middle of the day to prevent evaporation of moisture or water in transpiration. These pores are opened or closed depending on the state of the two surrounding guard cells.
The somata are found on both the upper and the lower leaf surface. in dicots, the stomata are noticeably denser on the lower leaf surface, while they are evenly distributed on both leaf surfaces on monocots.

Forest butterflies are often brown. This helps them to
Answer:
Avoid predators
Explanation:
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 helps make different types of carbohydrates?
Answer:
glycosidic bonds between monosaccharides that combine to form polysaccharides
Explanation:
The building blocks of carbohydrates are individual monosaccharides (i.e., sugar molecules), such as glucose, fructose, glucuronic acid, galactosamine, glucosamine, etc. These individual monomers of carbohydrates bond to form polysaccharides such as cellulose and starches. Monosaccharides form glycosidic bonds with an alcoholic OH group of a second monosaccharide to form a disaccharide (for example, lactose), and then these larger molecules bond together to form either linear or branched polysaccharides. Starch, for example, is a polysaccharide composed of monomers of glucose molecules.
