Answer:Primary consumers only obtain a fraction of the total solar energy—about 10%—captured by the producers they eat. The other 90% is used by the producer for growth, reproduction, and survival, or it is lost as heat. ... At each level, called a trophic level, about 90% of the energy is lost.

3 examples of non-living things that can disrupt homeostasis
Answer: This is what I could find on it.
There are many external factors that can disrupt homeostasis. Disease, toxins, and pathogens are just a few examples.
Some diseases can have external causes, like a toxin or pathogen invading the body. Toxins are products of plants, animals, fungi, or bacteria that hurt cells in some way.

Energy conversion within a plant cell would be limited most severely by removal of the cell's - A mitochondria B chloroplasts C ribosomes D endoplasmic reticulum
Answer:
The answer is Mitochondria. I took the test and that's the correct answer.
Energy conversion within a plant cell would be limited most severely by removal of the cell's by mitochondria.
What is mitochondria?Mitochondria are membrane-bound organelles (mitochondrial, singular) that produce most of the chemical energy required for biochemical reactions in cells.
The chemical energy produced by mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
Mitochondria contain their own small chromosomes. In general, mitochondria, and thus mitochondrial DNA, are inherited only from the mother.
Therefore, Energy conversion within a plant cell would be limited most severely by removal of the cell's by mitochondria.

write a five sentence paragrgh explaining the cell cycle
Answer:
The cell cycle is a cycle of stages that cells pass through to allow them to divide and produce new cells. It is sometimes referred to as the “cell division cycle” for that reason.
New cells are born through the division of their “parent” cell, producing two “daughter” cells from one single “parent” cell.
Daughter cells start life small, containing only half of the parent cell’s cytoplasm and only one copy of the DNA that is the cell’s “blueprint” or “source code” for survival. In order to divide and produce “daughter cells” of their own, the newborn cells must grow and produce more copies of vital cellular machinery – including their DNA.
The two main parts of the cell cycle are mitosis and interphase.
Mitosis is the phase of cell division, during which a “parent cell” divides to create two “daughter cells.”
The longest part of the cell cycle is called “interphase” – the phase of growth and DNA replication between mitotic cell divisions.
Both mitosis and interphase are divided into smaller sub-phases which need to be executed in order for cell division, growth, and development to proceed smoothly. Here we will focus on interphase, as the phases of mitosis have been covered in our “Mitosis” article.
Interphase consists of at least three distinct stages during which the cell grows, produces new organelles, replicates its DNA, and finally divides.

What is the primary (main) function of lipid molecules in the plasma membrane?
- To provide an energy source for most cell activities.
- To provide a substance for enzyme activity in the cell.
- To provide a place to collect and store waste products within the cell.
-To provide a barrier to the movement of substances in and out of the cell.
Answer:
to provide a barrier to the movement of substances in and out of the cell
Explanation:
Lipid molecules in the plasma membrane form a lipid bilayer which creates a semi-permeable barrier between the inside and the outside of the cell. Water and small molecules can cross the membrane. Other large molecules like ions cannot.
Hope that helps.

What keeps cells from growing indefinitely?
Answer:
Apoptosis
Explanation:
Apoptosis is a process that some cells go through when their embryo divides. It is programmed cell death. Apoptosis can help protect organisms from developing cancerous growths, or the uncontrolled growth/division of cells.
Well Cells are limited in size because the outside (the cell membrane) must transport the food and oxygen to the parts inside. As a cell gets bigger, the outside is unable to keep up with the inside, because the inside grows a faster rate than the outside.
what is sustainable development
Answer and Explanation
__________________________________________________________
According to UNESCO,
Sustainable development is the overarching paradigm of the United Nations. The concept of sustainable development was described by the 1987 Bruntland Commission Report as “development that meets the needs of the present without compromising the ability of future generations to meet their own needs.”
__________________________________________________________
There are four dimensions to sustainable development – society, environment, culture, and economy – which are intertwined, not separate. Sustainability is a paradigm for thinking about the future in which environmental, societal, and economic considerations are balanced in the pursuit of improved quality of life. For example, a prosperous society relies on a healthy environment to provide food and resources, safe drinking water, and clean air for its citizens.
__________________________________________________________
One might ask, what is the difference between sustainable development and sustainability? Sustainability is often thought of as a long-term goal (i.e. a more sustainable world), while sustainable development refers to the many processes and pathways to achieve it (e.g. sustainable agriculture and forestry, sustainable production and consumption, good government, research and technology transfer, education and training, etc.).

what would happen if your body failed to return to normal after exercising? explain.
Answer: if your question has to do with homeostasis here you go! i hope this helps:)
In order for a body to work optimally, it must operate in an environment of stability called homeostasis. When the body experiences stress—for example, from exercise or extreme temperatures—it can maintain a stable blood pressure and constant body temperature in part by dialing the heart rate up or down.
The loss of too much blood may lead to circulatory shock, a life-threatening condition in which the circulatory system is unable to maintain blood flow to adequately supply sufficient oxygen and other nutrients to the tissues to maintain cellular metabolism.
