A. Suzie Q wants to know the effect of different colors of light on the growth of plants. She believes that plants can survive best in white light. She buys 5 ferns of the same species, which are all approximately the same age and height. She places one in white light, one in blue light, one in green light, one in red light and one in the closet. All of the ferns are planted in Miracle-Grow and given 20 mL of water once a day for 2 weeks. After the two weeks, Suzie observes the plants and makes measurements.
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.

A.Trout do not have segmented bodies
B. Amoeba are multicellular
C. Trout and Koalas are in the same class
D. Koalas evolved after trout
Answer:
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.
What is a cladogram?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.

Which statement best describes the significance of meiosis to sexual reproduction?
A. It produces haploid gametes, with half the number of chromosomes.
B. It creates organisms with better adaptability to the environment.
C. It allows all types of cells to produce two sets of identical chromosomes.
D. It produces up to eight diploid cells, each with the same number of chromosomes.
In meiosis sexual reproduction produce haploid cells to produce gametes and chromosome number is reduced, hence option a is correct.
What is meiosis in sexual reproduction?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.

A.Interchange the labels inside ovals A and B
B. Interchange the labels inside ovals A and
C. Interchange the labels on the arrows 5 and 1.
D. Interchange the labels on the arrows 2 and 4.
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.
What do you mean by the rock cycle?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.

50 POINTS!!! Blood is a unique type of connective tissue that we haven't been able to synthetically create yet. For that reason donating blood is so essential to maintain the health of our population. If you are type O- blood, explain (in your words) the benefits and risks of being O-. Also, explain the differences between O+ and O- blood types.
Answer:
Difference between O positive and O negative
For example, a person with O+ blood does not have A or B antigens on the surface of the cells but does have Rh factor. In contrast, O- blood has no A or B antigens and no Rh factor. For this reason, medical experts consider type O- blood to be a universal red cell donor type

Consciousness can best be described as __(blank)__.
a) Internal chemical systems that are regulated by a circadian rhythm
b) an ability to sleep and have lucid dreams
c) a lack of awareness of things going on inside or outside of yourself
d) an awareness of things going on inside or outside of yourself
Consciousness can best be described as an awareness of things going on inside or outside of yourself, hence option D is correct.
How consciousness is regulated?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.
