I need some help in this area

Answer:

Though water has higher specific heat than land it can absorbs and releases heat slower than land.

Explanation:

The specific heat of the water is higher than land, that's why it has the tendency to absorb and release the heat slower as compared to the land. It also takes more heat to increase the temperature for one gram of water by one degree  than it also does to increase the temperature of the land. similarly the heat absorbed by the ocean is almost spread in the greater volume as the ocean is a transparent body.

Answer: photosynthesis

Explanation: leaves are a very important part of the plant. plants are autotrophic in nature. They can synthesize their own food. Leaves have green color pigment in it which is called chlorophyll.

Beach nourishment involves replacing sand on beaches to combat erosion, while vegetation management focuses on planting native vegetation to stabilize the sand. Both aim to protect against erosion but have different methodologies and impacts, with nourishment sometimes leading to ecological issues if not conducted responsibly.

Beach nourishment and vegetation management are both strategies to combat beach erosion, but they operate in different ways. Beach nourishment involves the addition of sand or sediment to a beach to combat erosion by replenishing the beach system. It does not typically use hard structures, contrary to breakwaters or sea walls; these are different methods known as 'hard engineering' techniques. Instead, beach nourishment provides a softer approach with the added sand acting as a buffer to wave energy.

In contrast, vegetation management attempts to stabilize the sand by planting native vegetation. These plants help in holding the soil together with their root systems and provide protection against erosive forces such as wind and water. It is essential to understand that vegetation management does not directly replace sand; rather, it helps to prevent its loss over time.

Beach nourishment might provide incidental protection from floods by bolstering the beach's width and height, thus acting as a barrier to storm surges; however, this is not its primary purpose. Vegetation management can also help in this regard by stabilizing the soil and reducing the potential for erosion during storm events.

It is important to recognize that while both methods aim to protect against erosion, they must be applied thoughtfully. Dredging, which is sometimes associated with beach nourishment, can cause significant ecological damage, as seen in the degradation of reefs, sea grass beds, and the loss of marine life, consequently affecting local economies reliant on fisheries and tourism.

Final answer:

Beach nourishment involves adding sand to replenish eroded areas, while vegetation management focuses on planting and maintaining vegetation along the beach to stabilize sand and prevent erosion. Beach nourishment uses hard structures, while vegetation management does not.

Explanation:

Beach nourishment and vegetation management are two different methods used to manage beach erosion. Beach nourishment involves adding sand or sediment to the beach to replenish eroded areas. This is typically done using large-scale dredging and pumping operations. On the other hand, vegetation management focuses on planting and maintaining vegetation along the beach to stabilize sand and prevent erosion. This can include using beach grass, shrubs, and trees to trap and hold sand, as well as creating natural barriers against wave action. Unlike beach nourishment, vegetation management does not involve the use of hard structures such as seawalls or groins.

Which of the following would be a result of eutrophication of nitrogen?

-undergrowth of water plants

-hypoxia, or low levels of oxygen

-Decreased decomposition

-inactivity of fertilizers

Answer:

Eutrophication results from the increased amount of fertilizers in local water bodies like ponds or lakes. This actually results in the hypoxia or decreased oxygen content of the water bodies.

Option B

Eutrophication is seen in the water bodies that are located beside the agricultural fields. This actually occurs when rain water or water from different sources come into the water bodies. This leads to huge outgrowth of water weeds and this actually decreases oxygen content of water in two ways. Firstly, they consume a lot of oxygen dissolved in water. Secondly they block the sunlight entering inside water, thereby preventing photosynthesis from aquatic plants. Thus, the hypoxia exists in water which kills the aquatic animals like fishes etc. This condition can be prevented by application of several other ways like removing the weeds and purifying the water of the ponds etc. Else this will contaminate the whole environment.

The field of genetic engineering has remained controversial ever since its existence. Some scientists extremely favour the recombinant DNA technology whereas others consider it to be dangerous.

Some of the positive impacts would be that these animals would provide better milk quality and quantity. The meat of these animals will be able to provide better nutrition. Hence, in this way these animals will help to fight malnutrition.

The negative impacts of such animals would be that one never knows that if a mutation occurs in these organism than how dangerous it could be for the world. There is also a threat that the genetically engineered animals if mated with the wild life can cause threats. It might also lead to the wild- life of animals being extinct.

Answer:

They can speed up metabolic processes in the body

Explanation:

Enzymes are specific in action

They are protein in nature

Final answer:

Enzymes are specific catalysts that speed up metabolic processes by lowering activation energy and can be reused after reactions; they also change shape for substrate binding.

Explanation:

The true statement about enzymes is that they can speed up metabolic processes in the body. Enzymes achieve this by acting as biological catalysts that lower the activation energy of reactions. They are highly specific and do not act on nonspecific, randomly chosen substrates. Contrary to being single-use, after a reaction enzymes can be reused as they are not consumed in the reactions they catalyze. Lastly, enzymes can and do often change shape, undergoing conformational changes upon substrate binding based on the induced fit model.

Final answer:

Animals have different structures that perform similar functions due to convergent evolution, such as gills and lungs. Convergent evolution occurs when unrelated organisms adapt to similar environmental conditions and develop analogous structures.

Explanation:

Animals have different structures that perform similar functions due to the process of convergent evolution. Convergent evolution occurs when unrelated organisms adapt to similar environmental conditions and evolve similar structures to carry out the same function. These structures are called analogous structures. For example, gills in fish and lungs in mammals are both respiratory organs that allow for the exchange of oxygen and carbon dioxide, but they evolved independently in these two groups of animals.

Answer:

Planning how to transport water; using technology to purify water; building structures to store water.

Explanation:

 Water source management is a set of actions to regulate and control the use and protect these vital sources. Management must be done in accordance with current legislation and in order to preserve the quantity and quality of water.  The management of water resources aims to ensure the availability and quality of water for its various uses, including public supply and preservation of the environment.

  For this, they require several actions such as preservation and restoration of riparian forests, preservation of springs, techniques of management of agricultural soils and pastures, implementation of collecting networks and sewage treatment plants, collection and treatment of urban waste and industrial effluents, among others. many others.  Other actions like planning how to transport water (to avoid contamination of the water), using technology to purify water, to make it possible to renovate the source, building structures to store water to avoid contammination.

Plants use light energy to produce food molecules during photosynthesis and obtain cellular energy from the bonds of these food molecules during cellular respiration.

The chlorophyll pigment in plants harnesses light energy to ‘manufacture’ glucose/carbohydrates which are later used by the plant for cellular respiration to power cell activities.

Explanation:

The energy from sunlight is used by the chlorophyll pigments to make ATPs through a process called photophosphorylation. In addition, the light energy is used to split  water molecules into H⁺  and O²⁻. The H⁺ is then captured by NADP+ which is reduced to NADPH, while O²⁻ is evolved as oxygen. This occurs in the light stage of photosynthesis.

The NADPH is used to reduce carbon dioxide into glucose in the dark stage (Calvin cycle) of photosynthesis. Remember since this is an anabolic process ATPs (the one created through photophosphorylation) are used to power this cycle.

Excess glucose can be converted to starch and stored. Otherwise, the energy captured in the chemical bonds of the glucose are again utilized to make ATPs in cellular respiration.

Answer:

1) DNA is wrapped around histone proteins to form chromatin

2) The genes are the functional units, the segments between them are used for regulation

3) The genetic code is the language used, gene expression is how the cell uses the information, the activity of the genes.

Explanation:

1) DNA forms a DNA/protein complex called chromatin. It does this by wrapping around histone proteins. These histone proteins are usually present in the form of a nucleosome, which is a unit containing 2 copies of 4 histones (H2A, H2B, H3 and H4). The chromatin fibre at its most compact forms tightly coiled structures called chromosomes. These structures are only present during cell division. When the cell is in interphase (i.e. not dividing), the chromatin is not as tightly condensed, and instead the chromatin is more relaxed to allow the genes within to be expressed.

2) Genes are the functional units that the cell uses to make RNA and protein. The genes are first transcribed into RNA, which is processed and then translated into a polypeptide chain, which forms a complete protein that performs activities in the cell/tissue/organism. However, the whole genome does not form genes, there are regions that do not correspond to a gene. These regions are called "non-coding DNA" or sometimes even "junk DNA". However, that does not mean that these regions do not have important roles. The role of this DNA is usually in regulating the activity of the nearby genes. This DNA might contain important regulatory sequences such as promoters/enhancers/silencers that control how the gene is used by the cell, by for example, recruiting transcription factors or silencing proteins.

3) The genetic code is the language used by the cell. It explains how the cell can transcribe the information in the DNA, to RNA, process the RNA, and then translate the RNA into a polypeptide, and eventually a mature protein. In contrast, gene expression represents how the cell actually uses this information. Not all the genes are transcribed at the same time, instead, the activity of genes is carefully controlled to produce appropriate gene expression patterns, allowing the cell to properly perform its functions. Gene expression is hugely different between cells in an organism, for example the gene expression patterns of a muscle cell will  be hugely different to that of a blood cell.

Answer:

Very slowly

Explanation:

Even it may seem that the glacier is moving rapidly, it moves very slowly. It is a solid block of ice and that ice is making it move, as the pressure on the ice enters the block.

As the ice is melting around the glacier, it helps him slide and move. Glaciers are moving as a response to climate change. The glacier moves the fastest on the points where the ice is thinner and there is no friction. While glacier has enough amount of snow and ice, it will move.
