Answer:
Divergent plate boundaries.
Explanation:
"As upwelling of magma continues, the plates continue to diverge, a process known as seafloor spreading. Samples collected from the ocean floor show that the age of oceanic crust increases with distance from the spreading centre".

Explanation:
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.

Explanation:
can somebody help me make a claim , evidence and reasoning on “Do you think school days should be made longer?
i need it now please help me
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.

what do you think causes different phenotypes in organisms how does the phenotype depend on its genes (genotype)
Answer:
They difference in phenotypes is dependent on the genes. The more dominant gene will overpower a recessive gene, or if there are two recessive genes together, that will be the phenotype. When things are cross breaded they introduce different genotypes that allow for different looking phenotypes.
Example: Dominant blue flower (Bb) mixed with recessive yellow flower (bb)
B b
b Bb bb
b Bb bb
There is a 50/50 chance the offspring will be either blue or yellow
The differences in phenotypes are determined by genes. The more dominant gene will completely overwhelm a recessive gene, or if two recessive genes coexist, the phenotype will be that. When things are crossbred, unique genotypes are introduced, allowing for different-looking phenotypes.
What is phenotype?A "phenotype" is simply an observable trait. "Pheno" simply means "observe," and it derives from the same root as "phenomenon."
The differences in phenotypes are determined by genes. The more dominant gene will completely overwhelm a recessive gene, or if two recessive genes coexist, the phenotype will be that.
When things are crossbred, unique genotypes are introduced, allowing for different-looking phenotypes.
Thus, in this way, phenotype is dependent on genotype of the organism.

when placed in a glucose solution, yeast cells will produce bubbles. which process are the yeast cells carrying out? A. chemosynthesis B. respiration C. photosynthesis D. transpiration
Answer:
B. respiration
Explanation:
There's a Quizlet called "Biology 1st 9 weeks review" (it's created by Rodgerst4) that helped me!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.

What happened when Earth's first atmosphere collapsed? Will mark you as brainliest!
- it created oxygen
-it formed the oceans
-it triggered an ice age
-it fell as rain, watering the earliest plants
Explanation:
solar radiation would break atmospheric water into oxygen, which would react with carbon on the Earth to form carbon dioxide. The air would still be too thin to breathe. The lack of atmosphere would chill the Earth's surface.Plants and land animals would die
How are graphemes related to synesthesia?
Grapheme-color synesthesia is a consistent brain-related phenomenon. A syneshete automatically associates distinct, consistent colors with certain letters, numbers, and/or words. A word that is printed in black on a page or wall in front of you will carry its own specific color when you see it.
Answer:
Grapheme–color synesthesia or colored grapheme synesthesia is a form of synesthesia in which an individual's perception of numerals and letters is associated with the experience of colors. Like all forms of synesthesia, grapheme–color synesthesia is involuntary, consistent and memorable.
