Explanation:
Groundwater is water that occupies the zone of saturation within the ground. The water table is the upper limit of the groundwater. An aquifer is a body of porous rock or sediment saturated with groundwater. Groundwater enters an aquifer as precipitation seeps through the soil. It can move through the aquifer and resurface through springs and wells. Groundwater separated from atmospheric pressure by relatively impermeable material is termed confined groundwater. When such zones are penetrated by wells, the water rises above the point at which it was first found because a confined aquifer is under pressure exceeding that of atmospheric pressure.
Climate change has begun to affect insects as food resources have started disappearing . The monarch butterfly and the queen butterfly have to compete for the same food source . This is an example of____competition.
A. Co-species
B. Intraspecies
C. Interspecies
D. Habitat
Answer:
B.
Explanation:
In an ecological environment living things of different or same species compete with each other for the limited resources available. It is a symbiotic interaction between these living things.
There are two types of competition between these living beings- intraspecific and interspecific. In the given scenario, it is an intraspecific competition between the monarch butterfly and the queen butterfly.
Intraspecific competition is a competition between two living beings of the same species.
The monarch butterfly and the queen butterfly both belong to the same species- danaus.
Therefore, option B is correct.

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.

Immunological memory accounts for: Group of answer choices the observation that some strains of the pathogen that causes dengue fever cause more severe disease than others the ancient observation that someone who had recovered from the plague could safely care for those newly diseased the human body's ability to distinguish self from non-self the ability of a helper T cell to signal B cells via cytokines
Answer:
The correct answer is - the ancient observation that someone who had recovered from the plague could safely care for those newly diseased.
Explanation:
Immunological memory is the ability of the body to recognize or identify and kill or remove the antigen, very quickly and faster, the body has previously encountered and developed an immunological response.
These memories are developed due to memory B cells or, memory CD8+ T cells and memory CD4+ cells developed by the first-time immune response. If someone who had recovered from the plague must have developed memory cells for the antigen and safer than those newly diseased.
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.

1.ions
2. electrolytes
3. nonpolar compounds
4. nonelectrolytes
Answer: what are the choices
Explanation: hi
When dissolved in water, electrolytes produce solutions of ions. The correct option is 2.
What are electrolytes?When electrolytes are dissolved in water or other solvents, they produce ion solutions that conduct electricity.
These ions, which can be positively or negatively charged (cations or anions), form when the electrolyte dissociates into its constituent atoms or molecules in the presence of a solvent.
Electrolytes include ions such as sodium, potassium, calcium, magnesium, chloride, bicarbonate, and phosphate.
These electrolytes are important in many physiological processes in the body, including fluid balance, nerve impulse transmission, and muscle function.
Food and drink, supplements, and intravenous fluids are all sources of electrolytes.
Thus, the correct option is 2.

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.
A cylindrical tin full of engine oil has a diameter of 12cm and a height of 14cm.The oil is poured into a rectangular tin 16cm long and 11cm wide. What is the depth of the oil in the tin?
Answer:
Depth = 9 cm
Explanation:
First, calculate the volume of the cylindrical tin.
Mathematically, that would be the following:
[tex]V = \pi * r^{2} * h[/tex]
Now, r = d/2 = 12/2 = 6 cm
h = 9 cm
Therefore, the volume will be:
V = 22/7 * 14 * 6^2 =1,584 cm^3
Now, to find the the depth of the tin, we have to realize that the content of the cylinder should fill in the tin to a particular height.
As we don't have the height of the tin so let's suppose it x, now it means that
l * b * h = 16 * 11 * x = 176x
Therefore, the depth would be:
176x = 1584
x = 1584 / 176 = 9 cm
