Answers

Answer 1

Answer:

with radiators that release electromagnetic radiation into space.

Explanation:

Spacecraft use radiators that release electromagnetic radiation into space to get rid of excess heat.

Since outer space is a near perfect vacuum, this means that many of the common ways that heat is expelled on Earth do not work in space. Since spacecraft do not touch any other objects in space, they cannot lose heat through conduction. Since there is no air, they cannot lose heat through convection either. Instead, spacecraft use specially designed radiators, which emit excess heat as electromagnetic radiation—infrared light.

There are four basic functions of soil as a medium for plant growth:
, water, oxygen and nutrients.

Answers

Final answer:

Soil serves four basic functions as a medium for plant growth: providing structural support, offering water, enabling oxygen access, and delivering essential nutrients. These elements together create an environment conducive to plant development and growth.

Explanation:

The four basic functions of soil that support plant growth include supporting the plant structure, providing water, allowing gas exchange (oxygen), and supplying nutrients. Soil provides a substrate for the plants, where they anchor their roots to help them stay upright. It also has the ability to store and provide water to the plant, which is essential for its survival. Soil plays a crucial role in allowing airflow (specifically oxygen) to the plant's roots. This is crucial for respiration, a vital process in plant growth. Lastly, soil contains essential nutrients that are indispensable for plant growth, including nitrogen, phosphorus, and potassium among others. These nutrients are absorbed by the plant roots and used for various biological functions.

Answer:

None of these two

Explanation:

An unsaturated fatty acid must contain a double bond in the poly carbon chain other than the double bond in the functional group. In these two, images there exists a double bond in the carboxylic group i.e –COOH.

A. The population will increase quickly.
O
B. The population remains the same.
O
C. The population will decrease.
O
D. The population will increase slowly.​

Answers

Answer:

C

Explanation:

When the number of organisms in an environment is higher than the carrying capacity, the population most probably will decrease. Thus, the correct option is C.

What is the carrying capacity?

The carrying capacity may be defined as the maximum number of individuals that can be supported by a habitat. Every habitat has a fixed carrying capacity. The carrying capacity of the habitat primarily depends on two factors. They are as follows:

The Food to eat.The space to live.

When the number of organisms in an environment is higher than the carrying capacity, they feel the scarcity or limitation of food to eat and space to live, this creates more competition between the members of the same or different species.

Thus, the offspring who have favorable variations of relative fitness will survive, and the rest will be eliminated by a habitat. The population will most probably fall down.

Therefore, when the number of organisms in an environment is higher than the carrying capacity, the population most probably will decrease. Thus, the correct option is C.

Write a script for a 60-second commercial to help persuade hunters and fishers to take wildlife responsibly. In your commercial, inform they why illegal hunting or overfishing can harm an ecosystem and tell them about laws that deal with this issue. Please help!!!

Answers

Final answer:

Irresponsible practices such as illegal hunting and overfishing lead to habitat destruction and species extinction. Overharvesting is a key issue, particularly for aquatic species and contributes to the collapse of various fisheries. Laws such as the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) treaty, have been implemented to counter these problems.

Explanation:

Illegal hunting and overfishing can detrimentally impact ecosystems, causing habitat destruction and leading to species extinction. Rivers and streams, often inhabited by a diverse range of aquatic species are modified through damming or water removal, reducing their population. Examples of such occurrences are seen in the United States where 91 percent of rivers have been affected.

Overharvesting through illegal hunting or fishing has manifested itself as a serious threat to many species, particularly aquatic species. Fishery collapse, for instance, the western Atlantic cod fishery collapse, is driven by economic and political factors leading to overexploitation. The widespread unregulated fishing activities, coupled with the capacity for overfishing offered by advanced technologies, exacerbates this issue.

Numerous laws have been enacted globally to protect species and ensure responsible wildlife management. The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) treaty and national legislation assist in preventing listed species from being transported across nations' borders. Despite the challenges in enforcement, these legal frameworks play a significant role in protecting the environment and the diverse species within it.

The common ancestor of these three organisms did not have lungs. So, the correct option is (B).

What is Lungs?

Lungs are described as a pair of organs present in the chest that supplies oxygen to the body, and removes carbon dioxide from the body.

The lungs and respiratory system allow us to breathe which brings oxygen into our body which is known as inspiration or inhalation and removes carbon dioxide which is known as expiration or exhalation. This exchange of oxygen and carbon dioxide is called respiration.

The lungs are divided into segments or lobes with the right lung having three lobes while the slightly larger left lung has two lobes. These are separated by the mediastinum which contains the heart, trachea, esophagus and many lymph nodes.

Thus, the common ancestor of these three organisms did not have lungs. So, the correct option is (B).

Use the same article to answer the following question. Lung Transplants When are lung transplants performed? What are the risks of lung transplants?

Answers

Answer:

When are lung transplants performed?

When the body's lungs are destroyed or the lungs have a disease on them and need to be transplanted immediately.

What are the risks of lung transplants?

The body may reject these lungs rendering them useless.

Lung transplants are typically performed for end-stage respiratory diseases to improve quality and life expectancy, but carry risks like organ rejection, infections, and complications from medications.

Lung transplants are performed when a person's lungs are severely damaged and no longer function properly. This is often the result of chronic respiratory diseases or conditions such as COPD, cystic fibrosis, idiopathic pulmonary fibrosis, and advanced lung cancer. Transplants aim to improve both the quality and expectancy of life for patients with these end-stage lung diseases. However, lung transplants carry significant risks, including rejection of the transplanted organ by the patient’s immune system, infections, and side effects from immunosuppressive medications necessary to reduce the risk of organ rejection.The risks associated with lung transplants can be substantial. Rejection is a common issue, occurring when the body's immune system attacks the new organ. Infections are also a concern, particularly because the drugs used to prevent rejection can weaken the immune system. Another risk is organ failure, which may result from various complications related to the surgery or from the transplanted lungs themselves not functioning as intended.Long-term care and monitoring are imperative after a lung transplant, with the goal of managing and mitigating these risks as much as possible to ensure the longevity and quality of life for the transplant recipient.

The state of California has over 1,000 dams, many built from the 1930s to the 1970s to reduce flooding and to create hydroelectric power. A dramatic decrease in salmon and trout populations were noted in the dammed rivers. The state has recently begun to research dam removal to restore rivers to their original flow. Which of the following is a possible benefit of removing some dams?
A. Restoration of migrating fish habitats and related food web species.
B. Increased hydroelectric power output from remaining California dams.
C. Better long-term drought prevention from reservoirs.
D. A decrease in flooding events downstream from where the dam is removed.

Answers

Answer: A. Restoration of migrating fish habitats and related food web species.

Explanation:

The removal of dam is likely to increase the incidences of flood because of overflow of river water, it will also decrease the output of electricity generation in California. The dam can keep the river water in a circulation hence can also prevent it to dry. Thus without dam the river water is expected to dry and condition of drought may result in California.

The removal of dam will help in restoring the biodiversity of the free flowing river. The marine animals can migrate in river water which has been restricted from flowing. The salmon and tout populations may get restored in terms of numbers. Also, this initiative will restore the food web as many marine species are dependent on each other for food needs.
