Answers

Answer 1

Answer:

B) open ocean

Explanation:

The open ocean ecosystems have the least available nutrients and lowest productivity. The limiting factors in an marine habitat are light and nutrients. Coastal ecosystems, estuaries and coral reefs have much higher nutrient availability and high productivity because plants are in shallow water and receive plenty of sunlight.

A neutron star collapses into a black hole because of the force of (fusion,gravity)

Answers

Gravity

Neutron stars are the most extreme and fascinating objects known to exist in our universe: Such a star has a mass that is up to twice that of the sun but a radius of only a dozen kilometers: hence it has an enormous density, thousands of billions of times that of the densest element on Earth. An important property of neutron stars, distinguishing them from normal stars, is that their mass cannot grow without bound. Indeed, if a nonrotating star increases its mass, also its density will increase. Normally this will lead to a new equilibrium and the star can live stably in this state for thousands of years. This process, however, cannot repeat indefinitely and the accreting star will reach a mass above which no physical pressure will prevent it from collapsing to a black hole. The critical mass when this happens is called the "maximum mass" and represents an upper limit to the mass that a nonrotating neutron star can be.

However, once the maximum mass is reached, the star also has an alternative to the collapse: it can rotate. A rotating star, in fact, can support a mass larger than if it was nonrotating, simply because the additional centrifugal force can help balance the gravitational force. Also in this case, however, the star cannot be arbitrarily massive because an increase in mass must be accompanied by an increase in the rotation and there is a limit to how fast a star can rotate before breaking apart. Hence, for any neutron star, there is an absolute maximum mass and is given by the largest mass of the fastest-spinning model.

spores

Answers

Seedless plants do not have seeds or stems making the answer c. spores

Spores are the structure which are present in both nonvascular plants and seedless vascular plants in common. Thus, the correct option is C.

What are vascular plants?

Vascular plants are also called tracheophytes. These plants form a large group of land plants which have lignified tissues for the conduction of water and minerals throughout the plant and a specialized non-lignified tissue for the conduction of products of photosynthesis.

The seedless vascular plants contain vascular tissue but do not produce flowers or seeds. In seedless vascular plants, like ferns and horsetails, they reproduce through haploid, unicellular spores instead of seeds.

Non-vascular plants do not have any vascular tissues. Non-vascular plants do not possess roots, stems, or leaves which were present in the vascular plants.

Therefore, the correct option is C.

Final answer:

Reforestation and reclamation are both processes that involve restoring and improving land by restoring vegetation and biodiversity.

Explanation:

Reforestation and reclamation are both processes that involve restoring and improving land.

Reforestation refers to the process of planting trees in an area that has been deforested or damaged by human activities. It aims to restore the natural forest ecosystem and increase biodiversity. For example, reforestation projects could involve planting a variety of tree species to recreate a diverse and healthy forest.

Reclamation involves restoring land that has been disturbed or damaged by activities such as mining or construction. It may include activities like soil remediation and reestablishing vegetation. An example of reclamation is when a former mining site is rehabilitated and turned into a natural habitat or farmland.

Although reforestation and reclamation have different focuses, they both aim to rehabilitate and improve the environment by restoring vegetation and biodiversity.

In your own words, explain what the summary equation tells you about cellular respiration.

Answers

Cellular respiration according to equation
                              C₂H₂O₂ + 6O₂ ⇒ 6CO₂ + 6H₂O + ATP
This equation tells that glucose molecule is broken down in the presence of oxygen into carbon dioxide, water and energy. However, its mechanism is not so simple, it complete in three steps. In first step also known as glycolysis, glucose molecule is broken down into two pyruvates with expenditure of energy. In second step and third step ( Kreb cycle and ETC) most of the energy is released in the form of ATP
Final answer:

The summary equation for cellular respiration represents the conversion of glucose and oxygen into carbon dioxide, water, and ATP, the opposite process of photosynthesis. It indicates how cells extract energy from food and helps maintain stable atmospheric levels of oxygen and carbon dioxide.

Explanation:

The summary equation for cellular respiration provides a concise description of the process by which cells convert glucose and oxygen into carbon dioxide, water, and chemical energy in the form of ATP (adenosine triphosphate). Specifically, the equation C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP represents the transformation of the energy contained in the bonds of glucose molecules into a form usable by cells for biological functions. This process is vital for the maintenance of life and is the mirror opposite of photosynthesis, where plants produce glucose and oxygen from carbon dioxide and water using energy from sunlight.

The exchange of carbon dioxide and oxygen through cellular respiration and photosynthesis worldwide helps to keep atmospheric oxygen and carbon dioxide at stable levels. Cellular respiration occurs in three stages: glycolysis, the Krebs cycle (also known as the citric acid cycle), and the electron transport chain. Each stage involves a series of biochemical reactions that progressively capture energy from glucose and transfer it into the high-energy phosphate bonds of ATP.

B is correct. It doesn't account for the population increase.

Answer is D.

There are many reasons for the rapid population growth rate in most developing countries is higher than in developed countries. Some of the major ones are: Women are least educated and they don't have easy access to birth control measures. Developing countries depend on agriculture and other farming activities. Children can be put to work at a young age to do these jobs. So, to improve economic condition of their families. Therefore, high fertility rate may not account to high population growth rate in most developing countries.
