1) what are the roles of plants, animals and decomposers in an ecosystem ??
Explanation:
Decomposers and scavengers break down dead plants and animals. They also break down the waste (poop) of other organisms. Decomposers are very important for any ecosystem. If they weren't in the ecosystem, the plants would not get essential nutrients, and dead matter and waste would pile up.

Which growth model is a realistic representation of population growth?
A realistic representation of population growth is the _____ growth model.
Answer:
Logistic Growth Model
Explanation:
The logistic model is realistic because it suggests the fact that the population of species is regulated and controlled by the carrying capacity (maximum members that an ecosystem supports) of the ecosystem. The population becomes small when the carrying capacity decreases.

Although all neurons are different, they do have some characteristics in common. What are these characteristics
Answer:
A cell body, an axon, and dendrites.
Explanation:
The similar characteristics of different neurons is their body structure which have the common parts in all neurons. All neurons have three essential parts i.e. a cell body, an axon, and dendrites. Neurons different in size, shape, and structure due to different in their role and location but all these different neurons have the same components of its structure such as cell body, an axon, and dendrites.

What do you mean by DNA transcription?The process of turning a piece of DNA into RNA is called transcription. Messenger RNA is said to be produced when DNA segments are transcribed into RNA molecules that can encode proteins.
DNA record is the cycle by which the hereditary data held inside DNA is re-composed into courier RNA (mRNA) by RNA polymerase. After that, this mRNA leaves the nucleus and serves as the foundation for DNA translation.
The nucleus is where transcription takes place. An RNA (mRNA) molecule is produced by using DNA as a template. During record, a strand of mRNA is made that is corresponding to a strand of DNA.

how would you relate the new pandemic (C0vID 19) in the imbalance of ecosystem due to biodiversity loss?
Random Answer = Report
Correct Answer = Brainliest
Answer:
Due to no controlling agent for harmful microbes that causes new pandemic.
Explanation:
The new pandemic leads to imbalance of ecosystem due to biodiversity loss because the absence of antimicrobial agent causes the pandemic. The antimicrobial agent is responsible for the control of harmful microorganism so due to disturbance in the ecosystem, the biodiversity losses occurs and there is no organism which stop or control the population of the harmful organism that causes new pandemic.
Which of the following energy transformation occur when humans use energy from food to exercise?
Answer:
Chemical energy from food molecules (potential energy) may also be transformed to mechanical energy (kinetic energy) when the body moves. In every energy transformation, some energy is given off as heat. This is why the body warms up during different activities like exercising, lifting weights, and even digestion!

A computational biologist develops a computationally intensive program for DNA sequence alignment. When they use distributed computing techniques to run the program on four computers in parallel, they find a speedup of 4. In this case, what does a speedup of 4 indicate
Answer: The program completed in a quarter of the time with four computers versus one computer
Explanation:
Distributed computing simply means using distributed systems in solving computational problems and this is done as the problem is divided into many tasks, whereby the tasks are accomplished by one or more computers.
Following the information given in the question, a speedup of 4 indicate that the program completed in a quarter of the time with four computers versus one computer.

Even though the tubers are genetically identical why the plants that grow from them may not be the same height ?
please explain
Please answer correctly.
Answer:
I've grown potatoes on top of loose earth that's covered by a thick layer of loose straw. It allows the green leafy parts to easily push through to the sunlight above while keeping developing tubers protected from light. I've grown them this way because I really enjoy the taste of fresh new potatoes and have no desire to store mature potatoes for winter. I want to get the most baby potatoes possible while not damaging the plants with tiny potatoes not big enough to eat yet. It also keeps the potatoes cleaner than if grown under the soil.
When I start lifting the straw back to pick the largest new potatoes, I can see the development of the other potatoes. While the biggest potatoes are 1 1/2 to 2 inches in size, others range in size all the way down to 1/4 inch or less.
When a specific garden plant blooms, most of the flowers open within a very short time period. Now think of tomato plants. The flowers continue to open over a period of months and both ripe tomatoes, large and small green tomatoes as well as flowers can all be found on the same plant. Not all the fruit will be ripe before cold weather kills the plant.
Potatoes are closely related to tomatoes and like tomatoes, not all the tubers will be full size when the plant dies back. So I'd say it's neither genetics nor environmental factors but the inherent life and growth cycle of potatoes that account for the tuber size difference.
The difference in the tuber size in plants of potatoes and tomatoes does not depend upon its genetics or environmental factors rather it depends upon the inherent life and growth cycle of the plant.
What is the growth cycle in potatoes?Growth cycles are the recurrent fluctuations in the series of deviations from the usual trend of the plant growth. Thus, the growth cycle contractions in the plant include slowdowns as well as absolute declines in the activity, whereas business cycles contractions include only the absolute declines or recessions.
Potatoes are the plant species which are closely related to tomatoes and just like tomatoes, not all the tubers will be full size when the plant dies back in time. So, it is neither the genetics nor the environmental factors but the inherent life and growth cycle of the potato plants that account for the tuber size difference in the plants which are genetically identical to each other.

Determine which of the following statements is true about energy in ecosystems A. Consumers pass on 20% of the energy they get from a lower trophic level. OB. Primary consumers lose 60% of the energy they absorb from producers as urine and feces. C. 10% of the energy Primary consumers absorb is lost as heat. Ons Primary producers lose 20% of the energy they absorb as urine and feces.
Answer: C. 10% of the energy Primary consumers absorb is lost as heat.
Explanation:
According to the ten percent law of energy flow only 10 percent energy is transferred from one trophic level to the next trophic level and rest of the energy is used to develop the biomass and lost as heat. As the loss of heat is an essential exothermic reaction after the digestion and assimilation of food the energy is lost as heat from the body of the primary consumers is 10%. Primary consumers are animals that are dependent on plants for their food requirements for example deer, goat and others.

You are viewing an organ of the respiratory system and note the following tissues: folded mucosal layer containing simple cuboidal epithelium and smooth muscle, shifting into simple squamous epithelia. Identify the organ.
Answer:
Respiratory bronchiole
Explanation:
The respiratory bronchioles represent the narrowest airways within the lung, being continuations of terminal bronchioles that have approx. 0.5 mm in size. The epithelium of the respiratory bronchiole is composed of cuboidal ciliated cells and a small number of non-ciliated (secretory) Clara cells. The respiratory bronchioles lead into alveolar ducts composed of smooth muscle and connective tissue (i.e., elastin and collagen), connecting the respiratory bronchioles to the alveolar sacs.
