The polysaccharide that is responsible for the strong structural nature of plant cell walls is
The polysaccharide that is responsible for the strong structural nature of cell walls of plants is cellulose.
The cellulose is an organic molecule that is made up of several units of glucose monomer. The cellulose which make up a large percentage of plant cell walls are composed of a network of several units of glucose monomer that are tightly linked together.
The cellulose, as well as lignin and hemicellulose, which constitutes the tensile fibers in the cell walls of plants, is the polysaccharide responsible for the strong structural nature of plant cell walls.

Over time, what will to happen to the populations of light and dark moths on light trees?
Answer:
Explanation:white moths will be spotted easier and killed and the population would drop while the dark moths population will rise
The population of white moths at the light tress will increase over time with the process of natural selection.
The trees are a light color population. Dark moths are unable to camouflage with the tress, while white moths camouflage with the trees.
What happens to white moths?The white and black moths at the tree are an example of a tree ecosystem. The moths are the target for the predators.
The process of natural selection is the evolutionary process with the survival of the fittest. The species that are able to survive in the inappropriate conditions are able to evolve.
In the tree ecosystem, the white moths are camouflaged with the trees. They will not be an easy target for predators. They will survive with the theory of natural selection.
The black moths are not camouflaged with the tree ecosystem. They are easily identified by the predators and are killed.
Thus, white moths are the fittest and with natural selection, they evolve.
Therefore, the population of white moths at the light tress will increase with natural selection.

Global warming is causing atmospheric CO2 levels to increase, which is expected to cause ocean acidification Which of the following is NOT a consequence of increased atmospheric CO2 levels?
a) decrease in the concentration of bicarbonate ions in the oceans
b) increase in the amount of carbonic acid formed in the oceans
c) decrease in the amount of calcium carbonate produced in the oceans
d) decrease in the concentration of carbonate ions in the oceans
e) increase in the concentration of hydrogen ions in the oceans
Answer:
This might not sound like much, but the pH scale is logarithmic, so this ... The ocean absorbs about 30% of the carbon dioxide (CO2) that is released in the atmosphere. As levels of atmospheric CO2 increase from human activity such as burning ... track and forecast ocean acidification, warming and other important ocean
An increase in atmospheric CO2 levels does not cause a decrease in the concentration of bicarbonate ions in the oceans.
WHAT IS OCEAN ACIDIFICATION?
Ocean acidification is the decrement in pH level of the ocean due to the absorption of carbon dioxide (CO2). Carbon dioxide is a gas that reacts with water to form carbonic acid (H2CO3), which makes the water acidic or have a low pH.CONSEQUENCE OF CO2 ABSORPTION IN OCEANS:
An increased CO2 level in the atmosphere means that the rate at which the ocean will absorb the atmospheric gas will it increase. Since CO2 is said to make the ocean acidic, the following will likely occur to increase acidity of the ocean:
Increase in the amount of carbonic acid (H2CO3) formed in the oceansDecrease in the amount of calcium carbonate (CaCO3) produced in the oceansDecrease in the concentration of carbonate ions (CO32-) in the oceansIncrease in the concentration of hydrogen ions (H+) in the oceansN.B: Bicarbonate ion (HCO3-) causes acidity, hence, the decrease of bicarbonate ions cannot be a consequence of ocean acidification.

Why are niches important to
ecosystems?
Answer:
Ecological niches allow species to exist in their environment. Under the right conditions, the species will thrive and play a unique role. Without the ecological niches, there would be less biodiversity, and the ecosystem would not be in balance.
If two species occupied the same niche, they would be competing for the exact same resources. The competitive exclusion principle states that one of the species would drive the other to extinction.

the average phosphate molecule spends 20000 to 100000 years cycling through the ocean. To speed the replenishment of the soil, farmers include large amounts of phosphate fertilizers which can runoff into streams, rivers, and the sea. What is a possible side effect of this?
Excess phosphate fertilizer produces a shortage across the entire region and hinders other agriculture
Excess phosphate fertilizer causes algae growth and oxygen decline, leading to fish kills and deadzones.
Excess phosphate washes up on the beaches, ruining the sand and shoreline.

How do plasmodesmata affect the individuality of the cells?
Answer:
[tex]{\fcolorbox{blue}{black}{\blue{answer}}}[/tex]
Plasmodesmata play roles in both cellular communication and in molecule translocation. Plant cells must work together as part of a multicellular organism (the plant); in other words, the individual cells must work to benefit the common good. Therefore, communication between cells is crucial for plant survival.

In recent years, people have become concerned over the loss of
ultraviolet rays from the sun.
because it protects the earth from damaging
1. Ozone
2. carbon dioxide
3. nitrous oxide
Answer:
1. Ozone
Explanation:
Ozone is a substance with the chemical formula, O3, found in the stratospheric part of the atmosphere. It functions to prevent the harmful ultraviolet (UV) radiation from the sun from reaching the Earth. However, due to anthropogenic activities i.e. human activities that releases greenhouse gases e.g. CO2, CFC etc. the protective function of the ozone layer is wavering.
Hence, based on this question, people are concerned over the fact that this OZONE layer is depleting, hence, risking the exposure to the harmful radiation from the sun.

Answer:
Fried Eggs are a perfect source for bacterium to feed on. It provides Ovalbumin, ovotransferrin, and ovomucoid. But a conflict would happen becasue eggs have lytic, which takes action against baxteira, so if there is enough of them the bacteria could take over the lytic in the egg and have a great feast.

Many different types of mutations can occur within the body. Sickle cell anemia is a disease that occurs when a mutation in the base pair of the hemoglobin beta gene causes a single replacement of the amino acid glutamic acid by the amino acid valin. As a result of this mutation the individual’s blood cells take on a sickle shape under certain conditions Which type of mutation causes sickle cell anemia
Answer:
POINT MUTATION (SUBSTITUTION)
Explanation:
A point mutation is that mutation which involves only one nucleotide base. Point mutation can, however, occur in different ways such as SUBSTITUTION. Substitution point mutation is that which involves the replacement of a single nucleotide base by another in a gene sequence.
This is the case in this question regarding the mutation that causes sickle cell anaemia. According to this question, Sickle cell anemia is a disease that occurs when a mutation in the base pair of the hemoglobin beta gene causes a SINGLE replacement of GLUTAMIC ACID (Glu) by VALINE (Val). This shows that it is a type of SUBSTITUTION POINT MUTATION.
