2) Aerobic respiration

Answer:

Answer: Option A and B.

Organ system and tissues.

Explanation:

The earthworm is a segmented worm that belongs to the phylum annelids. The earthworm has a close circulatory system just as human beings which means their blood circulates through a closed network of vessels which are connective tissues. The earthworm has a structure of 5 hearts and they are called aortic arches which are organ systems. These pump blood into a network of vessels and its flows through the body. From there, the blood moves to a dorsal blood vessel which sends blood to the front of the Earthworm, then to the ventral blood vessel which sends blood to the posterior. At the intestines, there are lateral vessels that carry nutrients away from the gut and to the body.

When the room is completely dark and the flashlight beam hits the blue paper, the blue paper will absorb most of the light and reflect the blue color back to the students' eyes.

Similarly, when the flashlight beam hits the red paper, the red paper will absorb most of the light and reflect the red color back to the students' eyes.

Since the room is dark and the light is not hitting any other objects or particles in the air, there won't be enough scattering or diffusion of light for the students to see the light traveling through the room itself. The light will essentially be confined to the illuminated areas on the blue and red papers.

Chemical energy

Explanation:

We get chemical energy from foods, which we use to run about, and move and talk (kinetic and sound energy). Chemical energies are stored in fuels which we burn to release thermal energy - this is one way of making electricity, see Electricity for more information.

B. Cars A and B are not accelerating because their speed is not changing.

Acceleration is defined as a change in an object's velocity, which includes changes in speed or changes in direction.

The formula for acceleration is given by:

Acceleration = (change in velocity) / (change in time)

The SI unit for acceleration is meters per second squared (m/s²).

Acceleration is an important concept in physics and is used to explain a wide range of phenomena, from the motion of objects in everyday life to the behavior of particles in subatomic physics.

The atomic number is given in the table along with the group and period they belong to, hence Lithium has the same number of energy levels as Beryllium, and Magnesium has the same number of energy levels as Sodium.

Atomic number can be defined as the number of protons or the positive charges that are present in the nucleus of an atom.

In the data given here in the table, it can be inferred that:

The number of energy levels, or shells, of electrons in an atom is determined by its position in the periodic table. Atoms in the same row or period of the periodic table have the same number of energy levels, while atoms in the same column or group have similar chemical and physical properties.

Hence, both lithium and beryllium have one energy level or shell of electrons and both magnesium and sodium have three energy levels or shells of electrons.

The nitrogen cycle is important to humans in the following way: it converts nitrogen into a form that humans can obtain by eating other organisms (option B).

Nitrogen cycle is the natural circulation of nitrogen in a series of processes by which nitrogen and its compounds are interconverted in the environment and in living organisms, including nitrogen fixation and decomposition.

During the nitrogen cycle, atmospheric nitrogen is converted to nitrogen oxides by lightning and deposited in the soil by rain, where it is assimilated by plants and either eaten by animals (and returned as faeces) or decomposed back to elemental nitrogen by bacteria.

The usable form of nitrogen that is assimilated by plants becomes accessible to humans when they consume the plants, hence, depicting the importance of the nitrogen cycle.

A given population has 25 individuals, all of genotype aa. His second population of this species has 40 individuals, all of the genotype aa. We assume that these populations are far apart but live under similar environmental conditions. Based on this information, the observed genetic variation is most likely due to genetic drift.

The Genetic drift is one of the random changes in the frequency of genetic variants present within a population. Genetic drift will completely eliminate the genetic variants, thereby reducing genetic variation. Also, initially rare alleles have become more common and may even become fixed. Today, recovered populations have very little genetic variation. Consider a population of rabbits with brown and white fur. White fur is the dominant allele.

Answer:

Hydrogen.

Explanation:

Hydrogen is the simplest chemical element that exists. The symbol for the chemical element Hydrogen is "H" and it is a colourless, tasteless, odorless, and highly flammable gas.

Hydrogen is a chemical element found in group (1) of the periodic table and as such it has one (1) electrons in its outermost shell. Therefore, Hydrogen has an atomic number of one (1) and a single valence electrons because it has only one proton and one electron in its nucleus.

Based on the octet rule which states that atoms of chemical elements gain, lose or share electrons so as to have eight (8) electrons in their valence shell. Therefore, atoms of chemical elements bond in order to attain the electronic configuration of a noble gas i.e a full valence shell which comprises of eight (8) electrons.

However, the chemical element "Hydrogen" is an exception to the octet rule because it is only able to hold a maximum of two (2) valence electrons in its outermost shell to become full.

Hence, Hydrogen is an element which does not want to have eight valence electrons.

C. The law of superposition and radioactive dating are the methods for measuring the age of Earth and its parts use absolute dating.

By analyzing the radioactive decay of isotopes or the effects of radiation on the crystal structure of minerals, absolute radiocarbon dating measure the amount of time since rocks first formed. Radiocarbon dating of wood or bones, potassium-argon dating, and trapped-charge dating methods like thermoluminescence dating of glazed pottery are instances of absolute dating procedures.

According to the principle of superposition in geology, the order of layers seen in sedimentary rocks reveals when the layers were deposited. According to the definition of the law of superposition, the lowest layer is the oldest layer of deposition, and the layers above it are incrementally younger layers of deposition.

A thermos keeps cold things cold in the same way. It doesn't contain some kind of cooling device. The same vacuum that keeps hot things hot keeps cold things cold. Heat that might otherwise transfer to the cold contents of the thermos is prevented from reaching it because of the vacuum between the thermos walls.

Today's thermoses are constructed much more sturdily than those in the past. The first thermoses featured metal exteriors with glass interior walls. These thermoses often ended up getting broken when accidentally dropped.

The resting phase of the cell cycle is called interphase.

Interphase is a critical stage in the cell cycle during which the cell prepares for division by going through different activities such as growth, DNA replication, and protein and organelle production. It is the longest phase of the cell cycle and is separated into three subphases: G1 (Gap 1), S (Synthesis), and G2 (Gap 2).

The cell develops in size, synthesises RNA and proteins, and performs its regular duties during the G1 phase. The cell enters the S phase after passing through the G1 checkpoint. The DNA of the cell is reproduced during the S phase, resulting in the production of two identical copies of each chromosome.

This ensures that during cell division, each daughter cell receives a complete set of genetic material. The cell enters the G2 phase after DNA replication, where it continues to expand and prepares for mitosis.

Interphase is not a real resting phase because the cell is actively engaged in multiple cellular functions. However, because the cell is not visibly dividing at this period, it is commonly referred to as the resting phase.
