Each level of the energy pyramid is called a trophic level. How does the amount of energy available to organisms differ at each trophic level in a food chain?
Answer:
Most of the food energy that enters a trophic level is "lost" as heat when it is used by organisms to power the normal activities of life. Thus, the higher the trophic level on the pyramid, the lower the amount of available energy
Cells with a full set of chromosomes are referred to as diploid or 2n, whereas cells with half the chromosomes are haploid or n. At which stage(s) of meiosis I are the cells diploid and at which stage(s) are they haploid
Answer:
Diploid → Prophase, metaphase, and anaphaseHaploid → TelophaseExplanation:
During prophase I, chromosomes get condensed. Each of the chromosomes gets in pair with its homologous one. They do so to make the crossing-over possible, a stage where they interchange their parts → 2n
During metaphase I, each of the homologous pairs is driven to the equatorial plane, where they randomly line up → 2n
During anaphase I, occurs the independent separation of homologous chromosomes that migrate to opposite poles of the cell. This separation generates different chromosomal combinations in the daughter cells. There are two alternatives per homologous pair → 2n
In telophase I, half of the chromosomes are already in one of the poles, while the other half is on the other pole. Each group of chromosomes has now half the number of the original cell. The nuclear membrane forms again in each pole → n
Finally, occurs cytokinesis, which involves the invagination of the cell membrane and cytoplasmic division.
The two new cells are ready for meiosis II.
Mitosis and Meiosis are the two types of cell division, in which the genetic material is replicated and transferred to the daughter cells.
The stages of meiosis in which chromosomes are diploid are prophase, metaphase, and anaphase. The haploid chromosomes are observed in telophase.
Meiosis is a reduction division in which genetic material is halved, such that a reduction in which diploid parent cells give rise to haploid daughter cells.
The stages of meiosis at which chromosomes are diploid and haploid are:
1. Prophase I is the first phase of meiosis I. The chromosomes are condensed and pair with the homologous chromosomes.
2. Metaphase I is characterized by the homologous pairs aligning at the equatorial plane.
3. Anaphase I is the independent separation of chromosomes, which migrate to opposite poles.
4. Telophase I is represented by the separation of chromosomes having a haploid number of chromosomes, which are now segregated into daughter cells.
Therefore, telophase I am the phase in which chromosomes are present in haploid numbers.

Scientific Definition of Mass:
Mass is the quantity of inertia (resistance to acceleration) possessed by an object or the proportion between force and acceleration referred to in Newton's Second Law of Motion (force equals mass times acceleration). In other words, the more mass an object has, the more force it takes to get it moving.

Which structure is found in the cytoplasm of
a typical plant cell?
A.vacuole
B. cell wall
C.chloroplast
D.cell membrane
Answer:
Explanation:
D
The structure that is found in the cytoplasm of plant cell is vacuole. The correct option is A.
What is vacuole?A vacuole is a cell organelle that is membrane-bound. Vacuoles are relatively tiny in animal cells and help to sequester waste material.
Vacuoles in plant cells aid in keeping water balance. A single vacuole can sometimes take up the majority of the interior space of a plant cell.
Within the cytoplasm of plant cells, there are also large, fluid-filled vesicles known as vacuoles.
Vacuoles typically make up about 30% of the volume of a cell, but they can fill up to 90% of the intracellular compartment.
Vacuoles are used by plant cells to regulate their size as well as turgor pressure.
Vacuole is a structure found within the cytoplasm of plant cells.
Thus, the correct option is A.

2. Which of the following best describes the genetic material a person receives from his or her father?
- 22 pairs of homologous chromosomes and an X and Y chromosome
- 22 haploid cells and an X or Y chromosome
- 23 diploid cells and an X and Y chromosome
- 22 autosomes and an X or Y chromosome
Answer:
22 autsomes and an X or y chromosome
Explanation:
Humans have 46 chromosomes. 23 from the mother and 23 from the father. The father has x and y chromosome. While the mother has two x chromosomes. 22 chromosomes each are given from both parents And the other chromosome (the 23rd) are the chromosomes for sex genes. Autosomes are all chromosomes that are not sex chromosomes. Therefore 22 autosomes are given from each parent. With reference to this questions 22 autsomes and one x or y chromosome will be given from the father.
After a copper smelter begins operation, local downwind populations of plants begin to adapt to the resulting air pollution. Scientists document, for example, that the acid tolerance of several plant species has increased significantly in the polluted area. This is an example of
Answer:
Adaptation.
Explanation:
Adaptation occurs when the acid tolerance of several plant species has increased significantly in the polluted area. The main reason for this tolerance is the change in the genetic makeup or mutation occurs in the cell due to the exposure of DNA to the chemicals of the environment that cause pollution. The plant adopt the environment by producing certain chemicals that cancel the effects of pollutants and as a result, the plant survive.
