In meiosis sexual reproduction produce haploid cells to produce gametes and chromosome number is reduced, hence option a is correct.

Gametes or sex cells, which are needed for sexual reproduction are created during meiosis.

It deactivates the sporophytic information while activating the genetic information for the production of sex cells.

Meiosis is a kind of cell division that results in the production of four gamete cells and a 50% reduction in the number of chromosomes in the parent cell. To develop egg and sperm cells for sexual reproduction, this procedure is necessary.

Therefore in sexually reproducing organisms meiosis is important to produce gametes, hence option a is correct.

C. Producing gametes for sexual reproductive purposes

Answer:

C. Producing gametes for sexual reproductive purposes.

Answer:

This question is incomplete, the complete part is: What is the independent variable in this experiment? A) The plant species B) The amount of water that each plant gets C) The amount of time D) The different types of light the plants were put under.

The answer is D

Explanation:

In an experiment, the INDEPENDENT VARIABLE is the variable that is changed or manipulated by the experimenter in order to effect a measurable response.

In this case, Suzie Q wants to know the effect of different colors of light on the growth of plants. She conducts this experiment using different colors of light namely: white light, green light, blue light, red light etc. This shows that the variable being changed/manipulated is the different colors of light. Hence, the INDEPENDENT VARIABLE is the DIFFERENT TYPES OF LIGHT THE PLANT WERE PUT UNDER.

According to the diagram of the rock cycle, the flaw can be corrected by interchanging the labels inside ovals A and B. The correct option is A.

The processes which involves the production and alteration of the different types of rocks that are found in the Earth's crust that make up the rock cycle.

The three main forms of rock include igneous, metamorphic, and sedimentary rocks. These are formed and decomposed according to various applications of heat and pressure on them throughout the time, and this process-based network is known as the rock cycle.

The reason the diagram for the many types of rocks and how they change is shaped into a circle gives rise to the name rock cycle. It resembles the rocks that goes through a cycle in certain ways. According to their location and circumstances, it appears that the rocks are recycled continuously and are transformed into various forms of rocks.

Therefore, according  to the diagram of the rock cycle, the flaw can be corrected by interchanging the labels which are inside ovals A and B.

Therefore, the correct option is A.

Answer:

i don't think so school days must be shorter and practical session must be longer theory is boring

Answer:

I think school days should not be made longer as this would impact the students mental health. Students attend school for approximately 7 hours a day in which they learn new content, this time being increased would cause stress and burden on students as classes would be longer and time spent at home would be less. Students need enough time to rest and relax their minds, as well as, spend time with their families. If extending school hours, students will have less time for self-care and family time which can lead to depression and loneliness. However, there are benefits of extending school hours such as more time to finish homework. But, a student's health must come first. In conclusions, school days should not be made longer.

Answer:

B. respiration

Explanation:

The bubbles produced when yeast cells are placed in a glucose solution is because the yeast cells are carrying out respiration. The correction option would be B.

Yeast cells are able to carry out a type of respiration known as anaerobic respiration when placed in a suitable substrate medium like glucose. During this process energy in the form of ATP is generated in the absence of oxygen for the metabolism of the yeast cells. The equation of the reaction is as follows:

[tex]C_6H_1_2O_6 --->2 C_2H_5OH + 2 CO_2[/tex]

Thus, the carbon dioxide gas is released as bubbles in the solution as a result of respiration.

Consciousness can best be described as an awareness of things going on inside or outside of yourself, hence option D is correct.

Wakefulness/arousal and awareness are frequently used as the two components that make up consciousness.

It appears that proper arousal levels and subsequently wakefulness, which is required for consciousness, depend on well-synchronized phases of awake and sleep.

Circadian rhythms are changes in the body, brain, and behavior that occur on a 24-hour cycle. Most living things, including animals, plants, and bacteria, are impacted by these natural processes, which predominantly react to light and darkness.

Therefore, the 24-hour cycle of normal physical, emotional, and behavioral changes that the body experiences.

Koalas evolved after trout.

Explanation:

A cladogram is the diagrammatical representation of the relationship between the organisms. From the cladogram, it can be said that Koalas evolved after trout. Thus, option D is correct.

A cladogram is used to show the relation between the different species through branching. It tells about the sequence in which the characteristics were derived.

From the cladogram, it can be seen that trouts developed the jaws, and amoeba are unicellular organisms. However, Trouts and Koalas do not share the same class but Koalas evolved after trout in the geological timeline of evolution.

Therefore, the Koalas evolved after trout.

Answer: Cytokinesis

Explanation: I am taking this same test right now and got it correct.

Cell division is completed when cytokinesis, which is the final step of mitosis, referring to cytoplasmic division, is completed. So the correct option is D.

A kind of cell division known as mitosis occurs when a single cell (the mother) splits into two genetically identical daughter cells. Mitosis, when referring to the cell cycle, is the stage of cell division during which the DNA in the cell's nucleus is divided into two identical sets of chromosomes.

Mitosis is used in the vast majority of cell divisions that take place in your body. Mitosis fills an organism's body with cells during development and growth, and it substitutes old, tattered new cells over the course of an organism's existence. Mitotic divisions are a kind of reproduction for single-celled eukaryotes like yeast, resulting in the generation of new members of the population.

In each of these scenarios, ensuring that each daughter cell receives a flawless, complete set of chromosomes is the "objective" of mitosis. In general, cells with too few or too many chromosomes don't function effectively; they may die off or potentially spread cancer. Thus, during mitosis, cells don't just randomly split their DNA into two heaps for the two daughter cells. Instead, they divided up their duplicate chromosomes in a methodical order.

Therefore the correct option is D.
