In a food pyramid, there is typically less biomass at the top (i.e., there are very few individual tertiary consumers, whereas there are numerous individual producers). In three to five sentences, explain this phenomenon, citing evidence relating to energy flow and how plants support ecosystems.
Answers
It is because of the 10% rule in the ecosystem, there are generally less biomass at the top.
The energy transfer in ecosystems:It is found that only 10% of the energy stored as biomass in a trophic level is carried forward to the next trophic level. This is called the 10% rule, due to this rule, the number of trophic levels an ecosystem can support is limited.
As one goes up in the food chain, only 10% of the energy is passed on to the next level, that is, about 90% of the energy is lost in the form of heat. At the bottom of the trophic level, there are producers, that is, plants, they get their energy from the Sun.
Further the plants are consumed by the primary consumers, and the energy is passed on. However, in the process, only 10% of the energy is passed on and the rest is lost in the form of heat. Further the primary consumer is consumed by the predator, which comes at the top of the food chain.
During the consumption of primary consumer, the same 10% energy is passed on and the rest is lost. This process continues and the energy is lost in the form of heat. With less energy at the top of the trophic level, only few individuals can be supported. This is the reason of less predators in comparison to prey.
Thus, it is the 10% rule, which results in lesser number of tertiary consumers in comparison to producers.

It is because of the 10% rule in the ecosystem, there are generally less biomass at the top.
Briefing:Only 10% of the energy produced by primary producers is used by consumers; the remaining 90% is wasted. Let's assume that a fox consumed a rabbit that had previously consumed grass and had retained 10% of its energy. As a result, the fox will only receive 1% because 10% of 10% is only 1%, and this will continue to trickle down to tertiary customers. In order for primary consumers to exist and for secondary consumers to be able to survive without primary consumers, ecosystems need plants, or primary producers. (Equally true for tertiary consumers).
Who is a Tertiary consumer?Quaternary consumers pounce on tertiary consumers. These quaternary consumers are frequently the apex predators, which indicates that their ecology is devoid of any predators. Animals like lions, polar bears, sharks, and hawks are some examples of quaternary consumers.

The image shows a spruce tree, which is a gymnosperm.
Which characteristic can be used to classify the tree as a gymnosperm rather than "any other type of seed" plant?
naked seeds
green leaves
thick bark
tall height
Answers
Answer: Naked Seeds
Explanation:
Gymnosperm means 'naked seed' and these were the earliest trees to evolve. They do not produce flowers and have seeds which are directly exposed to the air for wind pollination. Pine cones are one example. For ease you might think of the gymnosperms as conifers, such as yew and Scots pine.
The exposed seeds characteristic can be used to classify the tree as a gymnosperm rather than "any other type of seed" plant.
What is gymnosperm?Gymnosperms are a small category of plants that don't blossom and produce "exposed seeds."
Unlike angiosperms, or flowering plants, whose seeds are enclosed by fully developed ovaries, or fruits, gymnosperms, or any vascular plant, reproduce by the use of an exposed seed, or ovule.
Many gymnosperms bear their seeds in cones, which are known as "exposed seeds" because they are not visible until they are fully developed.
This means that unlike in a fruit, where the seeds are formed inside the reproductive structure, they are produced on the surface of the reproductive structure.
Therefore, option A is correct.

Cells are often compared to factories. How is a factory a useful model for explaining the cell?
Answers

Each organelle within the cell has its own important job, similar to factory workers. Every organelle plays an important role and without one, the whole team loses function.
Cell is the basic unit of life. Cells unite together and forms tissue. Many tissue will unite and form organ. Organ will unite together to form a organ system.
What is cell?The building elements known as cells make up all of these plants and animals, including worms in the soil, horseflies on farms, lemurs in the jungles, reeds in ponds, and trees in forests.
Similar to these instances, many live organisms are composed of numerous cells working together. However, certain forms of life, such as the various bacterial and protozoan species, are made up of simply one cell.
Most cells, whether they are solitary or a component of a multicellular organism, are too small to be seen without a light microscope.

Which two body systems maintain the level of glucose in the blood?
Answers
Answer:
The endocrine functions of the pancreas and liver coordinate efforts to maintain normal blood glucose levels.
The pancreas and liver regulate the level of glucose in the blood.
What is diabetes?Maintaining blood glucose is important for the body. The body needs glucose for the production of energy. The inability of the body to regulate blood glucose results is a result of diabetes. The blood glucose in our body is maintained by two hormones.
Insulin reduces the amount of glucose in the blood and glucagon increases the amount of glucose in the blood. Insulin and glucagon work together, in people without diabetes to maintain the blood glucose level of the body.
But in people affected by diabetes, insulin has either stopped working or insulin production by the body is inadequate compared to the body's requirements.
In type 2 diabetes, insulin production is low and in type 1 diabetes, there is resistance to insulin.
Insulin and glucagon are produced by the islets of Langerhans cells of the pancreas. In excess of insulin, the liver stores glucose from the blood, and in excess of glucagon, glucose is released by the liver into the blood.
Therefore, the pancreas and liver regulate the level of glucose in the blood.

After the transcription mRNA moves from the DNA to the ribosome out of the nucleus to perform the translation and produce amino acid chains. A Ribosome is the site of protein synthesis.
DNA or RNA both nucleic acids are made up of basic units known as nucleotides that join together to form ribonucleic and deoxyribonucleic acid.
RNA polymerase is the enzyme that binds with the DNA molecule and adds complementary sequences to build mRNA.
DNA molecules are double-stranded molecules that are attached to one another by the hydrogen bonds between the nitogenous basses whereas RNA molecules have only one strand in the structure.
mRNA plays the role of messenger between DNA molecule and ribosome molecule to carry out the genetic information coded in the DNA molecule to produce amino acids in the particular sequence to produce protein.

In the top left corner, an arrow going right is 4N, and an arrow pushing left is also 4N. Because they are equal numbers and in opposite directions, they cancel each other out, for a balanced net force of 0N.
In the bottom left, we have 4N pointed right and 5N pointed left. 5N (largest value) - 4N (smallest value) gives you an unbalanced net force of 1N.
On the top right both forces, 6N and 3N, are pointed in the same direction. Because of this, we add them to get a total 9N net force.
On the bottom right, 7N are going left and 2N are going right. Because they are opposing forces, we subtract 2N from the 7N to get a total of 5N.
Which of the following statements is Newton's 1st Law of Motion? A. The object will move in the direction of the unbalanced force. B. Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first. C. An object at rest remains at rest and an object in motion remains in motion at a constant speed and in a straight line, unless acted upon by an unbalanced force.

Answer:
C. An object at rest remains at rest and an object in motion remains in motion at a constant speed and in a straight line, unless acted upon by an unbalanced force.
Explanation:
In essence, Newton's first law of motion states that an object at rest won't move unless an outside force causes it to move. Similarly, an object moving at a constant speed will continue moving at that same speed indefinitely, unless an outside force causes it to change speed.
