What do meant by ecosystem?An ecosystem is a region where a bubble of life is created by plant, animals, and other things interacting with the weather, environment, and other factors. Abiotic variables, or inanimate matter parts, coexist with biotic components in ecosystems. Plants, animals, and certain other life are biotic factors.
Why the ecosystem is important?Healthy ecosystems keep our soil in perfect shape, purify the air, regulate the climate, animal wastes, and provide us with food. For the creation of remedies and other things, they provide resources and raw materials. They are the backbone of all civilizations and the drivers of our economies.

A box has 400 J of gravitational potential energy and weighs 100 N how many meters above the ground is it
Answers
Answer:
4 meters
Explanation:
The formula for gravitational potential energy is mgh, where m is the mass of the object in kilograms, g is the gravity, and h is the height in meters. You can use this to set up the following equation:
400=100 * h
h=4 meters
Hope this helps!
The gravitational potential energy is 400J of the box whose weight is 100N. Therefore, the height for which box is above the ground is 4 meters.
What is Gravitational Potential energy?
Gravitational potential energy is the energy which an object possesses because of its position above the ground level in a gravitational field such as the gravitational field of the Earth. The gravitational acceleration of the Earth can be assumed to be constant at about 9.8 m/s².
The gravitational potential energy can be calculated by the formula:
G.P.E = m × g × h
where, G.P.E = Gravitational Potential Energy,
m = mass of an object,
g = acceleration due to gravity = 9.8 m/s²,
h = height which the box attains
G.P.E = w × h (Since, w = m × g)
h = G.P.E. / w
h = 400J / 100N
h = 4 meters
Therefore, the height of the object is 4 meters.

Describe how C. parvum obtains the glucose it needs for glycolysis after it has infected another cell. Explain the role of lactate dehydrogenase in enabling C. parvum to continue producing ATP by glycolysis.
Answers
Answer:
Cryptosporidium parvum is an apicomplexan pathogen that obtains glucose either directly from its host or by the degradation of polysaccharides.
Explanation:
C. parvum only can produce ATP by glycolysis. Lactate dehydrogenase (LDH) is a universal enzyme required to synthesize pyruvate, which is the final product of the glycolysis process. This enzyme has been subject of research to understand the metabolism and evolution of apicomplexan parasites, including C. parvum.
Cryptosporidium parvum is a pathogenic agent that causes the disease cryptosporidiosis. The pathogen obtains glucose directly from the host. It can also obtain by the breakdown of polysaccharides.
C. parvum produces ATP through glycolysis. The enzyme lactate dehydrogenase is used by the C. parvum to generate metabolic ATP. It generates this ATP through the glycolytic pathway. The enzyme allows the conversion of NADH to NAD+. NAD+ is necessary for glycolysis to produce ATP. Metabolic energy plays a crucial role in the growth and proliferation of the pathogen in the host.
Some of the features of C. parvum are:
It consists of a unique lactate dehydrogenase enzyme to yield ATP. It causes the disease in the gastrointestinal tracts. The pathogen is used for research and understand its ability to obtain ATP directly from the host.Therefore, C. parvum consists of enzyme lactate dehydrogenase that helps in energy production through the glycolytic pathway.

The way of synthesizing food in green plants and autotrophic bacteria are same. Do you agree with the statement? Give reason.
Answers
Answer:
I do not agree with this statement.
Explanation:
Plants and some bacterias are autotrophic, meaning that they manufacture their own food from basic elements using an energy source in an anabolic process. Plants mostly utilize sunlight which they trap with the help of their green pigmentation called chlorophyll. Bacteria on the other hand mostly get their energy source by splitting chemical compounds, utilizing the liberated bond energy of the compound (examples is the sulfur bacteria) to fuel their food building process.

Homeostasis can require the control of many different variables in organisms. Homeostasis regarding internal body temperature is very important for many organisms. How is this different among ectotherms and endotherms?
Answers
Answer:
The term homeostasis refers to balance, where an organism seeks to maintain the balance of the temperature of its organism in order to persist in life.
There are organisms that are considered ectotherms, with which they release heat to the external environment in order to balance said increase in temperature and not denature their own proteins (such as enzymes, structural proteins, receptors, second messengers, etc.). On the other hand, in the case of endotherms, take energy from the medium to increase your body temperature and maintain it, since otherwise you could enter hypothermia.
In the human organism these principles occur both, not simultaneously, but according to the external temperature in which the human is, ectothermic / catabolic processes in heat stages and endothermic or anabolic processes in the cold stage.
Explanation:
In simple words, endotherm is the heat taken from the medium and exotherm or ectotherm is the release of heat to the medium.
This is so simple in objects, but in living organisms these processes have a reason, and that is why we explained above, when looking for a constant temperature these processes are responsible for mediating balance.

1. Describe one observation that supports the theory that mitochondria and chloroplasts originated as independent prokaryotic organisms
2.Explain how a symbiotic relationship like the one described in the endosymbiotic theory would have benefited each cell.
Answers
Answer: hope the below answers will help
Explanation:
1 and 2 in this paragraph
SKILLS TO DEVELOP
Briefly describe what is meant by the endosymbiotic theory.
Give some evidence supporting the theory that mitochondria and chloroplasts may have arisen from prokaryotic organisms.
It is thought that life arose on earth around four billion years ago. The endosymbiotic theory states that some of the organelles in today's eukaryotic cells were once prokaryotic microbes. In this theory, the first eukaryotic cell was probably an amoeba-like cell that got nutrients by phagocytosis and contained a nucleus that formed when a piece of the cytoplasmic membrane pinched off around the chromosomes. Some of these amoeba-like organisms ingested prokaryotic cells that then survived within the organism and developed a symbiotic relationship. Mitochondria formed when bacteria capable of aerobic respiration were ingested; chloroplasts formed when photosynthetic bacteria were ingested. They eventually lost their cell wall and much of their DNA because they were not of benefit within the host cell. Mitochondria and chloroplasts cannot grow outside their host cell.
Evidence for this is based on the following:
Chloroplasts are the same size as prokaryotic cells, divide by binary fission, and, like bacteria, have Fts proteins at their division plane. The mitochondria are the same size as prokaryotic cells, divide by binary fission, and the mitochondria of some protists have Fts homologs at their division plane.
Mitochondria and chloroplasts have their own DNA that is circular, not linear.
Mitochondria and chloroplasts have their own ribosomes that have 30S and 50S subunits, not 40S and 60S.
Several more primitive eukaryotic microbes, such as Giardia and Trichomonas have a nuclear membrane but no mitochondria.
Although evidence is less convincing, it is also possible that flagella and cilia may have come from spirochetes.

EXAMPLE 7.8.1
Briefly describe what is meant by the endosymbiotic theory.
Give three points of evidence supporting the theory that mitochondria and chloroplasts may have arisen from prokaryotic organisms.
Solutions
The endosymbiotic theory states that some of the organelles in eukaryotic cells were once prokaryotic microbes.
Mitochondria and chloroplasts are the same size as prokaryotic cells and divide by binary fission.
Mitochondria and chloroplasts have their own DNA which is circular, not linear.
Mitochondria and chloroplasts have their own ribosomes which have 30S and 50S subunits, not 40S and 60S.
Summary
The endosymbiotic theory states that mitochondria and chlopoplasts in today's eukaryotic cells were once separate prokaryotic microbes.
