what do you expect to happen to our oak populations? Explain how this could affect other organisms in the ecosystem.

Answers

As the oak populations decrease, the herbivorous consumers that have their habitats on them will start to become extinct as they are introduced to an environment that they are not used to and unprepared to survive in. As oaks keep forests healthy by maintaining a richer mix of plants, insects, birds and other animals wherever they grow. They are a source of food and habitat which adds emphasis to their importance to wildlife.

Possible setbacks are the difficulty in keeping up with market changes, failures in product production, failures in product distribution, sector problems, problems in the management of employees.

We can arrive at this answer because:

The management of a company is essential for its proper functioning and the success of the production.One of the first problems that lack of management causes is the difficulty in keeping up with market changes. This makes the company outdated and inefficient.Talking about the production and distribution of the product harms sales and reduces the number of customers.Sectoral problems hinder organized production, which will also affect sales.Problems in managing employees will also be disadvantageous, as it will affect all of the company's compositional factors.

Therefore, we can say that management is the most important point to be organized.

Applying the systems thinking techniques, outline the practical steps that can be taken to address drought

Answers

Some practical steps to address drought may include the implementation of efficient water usage techniques, the protection of vegetation, and the use of methods to retain moisture in the soil.

What is a drought?A drought is classified as the shortage or absence of water for a prolonged period of time in a region. These can be caused by a prolonged lack of rainfall.Other factors include poor water management and lack of vegetation.

Methods to avoid droughts.The planting and protection of vegetation, primarily those adapted to dry environments, is important in preventing drought.Furthermore, the correct implementation of efficient water usage techniques can aid in preventing drought by limiting the amount of water that is wasted. Lastly, the use of mulch and other water retainers can be an effective method in keeping the soil moist and aids in the previous two methods.

Therefore, we can confirm that the most effective ways to avoid droughts are to practice efficient water use so as to not waste water, to plant and protect vegetation, and to use mulch and other moisture-retaining methods to keep the soil from drying.

How do bogs keep themselves cool

Answers

Answer: Like humans, dogs need to keep themselves cool to protect their bodies. They do sweat, but not in the same way. They only have sweat glands only on the paw pads and nose leather. Since they are covered with fur, it is more challenging to keep their bodies cool.

After your dog runs around, you will notice that he begins to pant heavily. Dogs rely on panting to keep their bodies cool. Panting causes the evaporation of water from the nasal cavity, tongue, throat and lungs, which helps lower their body temperature.

They also experience the same dilation in blood vessels as humans, which brings blood to the surface of the skin, allowing the air in the environment to cool them.

Any dog is at risk for heat-related problems, especially in warm, humid weather. Our brachycephalic friends are at a much greater risk than their long-nosed counterparts. Large breeds with thick coats, such as Bernese Mountain dogs or Pyrenees are also more prone. Dogs with pre-existing heart conditions or respiratory issues are also more likely to be overcome by the heat.

When these dogs pant to try and cool themselves, they have to work harder to do so. This only raises their body temperature even higher, making it worse instead of better.

Rearrange the sentences into their most logical sequence to describe the process of energy extraction from glucose

Pyruvic acid passes from the cytoplasm into the mitochondrion.

Three molecules of ATP are produced with every pair of high-energy electrons that pass through the electron transport chain.

In total, about 36 ATP molecules are released from one molecule of glucose.

A small amount of energy is released when the bonds in a 6-carbon glucose are broken and rearranged into 3-carbon pyruvic acid molecules.

What is glycolysis?

Thus, the phases of cellular respiration should be performed in the following order: Krebs cycle, oxidative decarboxylation, electron transport chain, and oxidative phosphorylation are the steps in glycolysis.

The process of energy extraction from glucose:

When the bonds in 6-carbon glucose are broken and reorganized into 3-carbon pyruvic acid molecules, a little amount of energy is produced. Pyruvic acid enters the mitochondrion from the cytoplasm.

Carbon bonds are broken and rearranged in a sequence of events that release energy and carbon dioxide.

Every pair of high-energy electrons travels through the electron transport chain resulting in the production of three molecules of ATP. One glucose molecule releases roughly 36 ATP molecules in total.

Therefore,  the process of energy extraction from glucose start from pyruvate forming and end with the ATP formation.
