A. Oxidation
Explanation:
Three students are arguing about the reason that an apple appears red. Student A claims that it is because an apple absorbs the color red and reflects all other colors away from it. Student B claims that it is because an apple absorbs every other color of light and only reflects red light away from Student C argues that the apple gives off its own rays of red light. With which student do you agree and why?
Answer:
Objects appear different colours because they absorb some colours (wavelengths) and reflected or transmit other colours. ... For example, a red shirt looks red because the dye molecules in the fabric have absorbed the wavelengths of light from the violet/blue end of the spectrum.
Explanation:
adaptation of nerve cell
Answer:
They have a long fiber so they can carry messages up and down the body over long distances. In a stimulated neuron, an electrical nerve impulse passes along the axon. The axon is insulated by a fatty sheath - the fatty sheath increases the speed of the nerve impulses along the neuron.
Explanation:
During mammalian embryogenesis, the first differentiation event that occurs leads to a polarization of the outer cells of the 16-cell morula. This outer layer of cells forms the trophectoderm and the inner, apolar clump of cells become the inner cell mass. The inner cell mass will give rise to:
Answer:
the entire embryo
Explanation:
The trophectoderm refers to the polarized single cell layer that forms the wall of the blastocyst, thereby forming the first epithelium during embryogenesis. Moreover, the blastocyst is composed of 1-an inner cell mass (ICM) which will form all the tissues of the embryo's body, and 2-an outer layer composed of cells collectively called the trophoblast. The ICM of the blastocyst will form the embryoblast (which subsequently will give rise to the embryo itself) and the fetus, while the trophoblast will form all of the supporting tissues (i.e., amniotic sac, placenta, and umbilical cord). In humans, the blastocyst is the developmental stage of the embryo on day 5 after fertilization.

What is Climate Change?
Explain your answer.
What is Climate Change?
Climate change is a change in the usual weather found in a place.
How it helps us:
Studying the climate helps us predict how much rain the next winter might bring, or how far sea levels will rise due to warmer sea temperatures. ... We can also see which regions are most likely to be affected by extreme weather, or which wildlife species are threatened by climate change.
How it works:
As the earth's atmosphere heats up, it collects, retains, and drops more water, changing weather patterns and making wet areas wetter and dry areas drier. Higher temperatures worsen and increase the frequency of many types of disasters, including storms, floods, heat waves, and droughts.
How it affects us:
Human health is vulnerable to climate change. The changing environment is expected to cause more heat stress, an increase in waterborne diseases, poor air quality, and diseases transmitted by insects and rodents. Extreme weather events can compound many of these health threats.

Which statement correctly describes a feature of the rock cycle?
O Rocks are preserved through the process.
O Rocks change from one type to another.
O Different rock groups are not related to one another.
O Rocks change from one type to another in a specific order.
Answer:
The correct description of a feature of the rock cycle is:
O Rocks change from one type to another.
Explanation:
Sedimentary, metamorphic, and igneous rocks are the three main rock types. Together, they form the universal rock cycle. A sedimentary rock, for example, can change from its known state to another state by passing through crystallization, metamorphism, erosion, and sedimentation. There are no specific orders for the change. The processes that they pass through determine the resulting type.
Answer:
Rocks change from one type to another.

Answer:
100% of the offspring would be black fur, black eyes (16/16)
Explanation:
(Because the info. wasn't included here, I'm assuming black fur and black eyes are dominant, BBEE, to the recessive white fur and red eyes, bbee)
For BBEE x bbee, you'd create a typical dihybrid true-breeding punnett square , where the first top row would be BE , BE, BE , BE , and the vertical/side row would be be, be, be, be.
Cross these alleles as you would typically for any punnett square, and you'd see that all the offpsring would result in BbEe genotypes, which is true of any true-breeding dominant x recessive cross, which always results in the dominant phenotype being 100%.
So...
Black Fur and Black Eyes : 16/16 (100%)
Black Fur and Red Eyes: 0/16
White Fur and Black Eyes: 0/16
White Fur and Red Eyes: 0/16

How can embryos be more useful than adults to show evolutionary relationships among organisms?
Select one:
Related organisms always appear identical in embryonic stages.
Adults may have mutations that are not found in embryos.
Evolutionary relationships are more easily observed in more simple organisms.
Features found in embryos may not be found in adults.
Answer:
Related organisms always appear identical in embryonic stages.
Explanation:
Embryos of organisms that have a closer genetic relationship to one another tend to look similar for a longer period of time since they share a more recent common ancestor. Thus, embryology is frequently used as evidence of the theory of evolution and the radiation of species from a common ancestor.

How is mitosis different in plants and animals?
Answer:
The main difference is cell plate formation and how they form the daughter cells during cytokinesis. In plants, they lack centrosomes. A new cell plate will form between the daughter cells for the future cell wall. In animal cells the cell membrane will rather constrict to separates the parent cell into the daughter cells. Plants also do not undergo cell furrowing, unlike animals cells.
You are a botanist looking at the plant color in a new breed of Snapdragon. The two parent plants are Blue and Green and when you cross them you make F1 plants that are Cyan in color (a light aqua color). The ratio of offspring is as follows: There were 42 plants with Blue flowers (R1), 39 plants with Green flowers (R2) and 86 plants with Cyan flowers. Is the number of your progeny consistent with a single-gene incomplete dominance inheritance pattern
Answer:
Incomplete dominance is the inheritance pattern where the dominant allele did not mask the recessive allele completely and form a mix of both alleles. Here the inheritance is the incomplete inheritance. The ratio of F2 generation is 1:2:1.
Given:
R1R1 = 42
R2R2 = 39
R1R2 = 86
Total R1 alleles = 2*42+86 = 170
Total R2 alleles = 2*39+86 = 164
Total alleles = 334
Frequency of allele R1 = 170/334 = 0.51
Frequency of allele R2 = 164 / 334 = 0.49
Expected number of each phenotype:
Total population = 167
Blue = R1R1 = 0.51 * 0.51 * 167 = 43.44
Green = R2R2 = 0.49 * 0.49 * 167 = 40.10
Cyan = 2*R1*R2 = 2*0.51*0.49*167 = 83.46
Phenotype Observed(O) Expected (E) O-E (O-E)2 (O-E)2/E
Blue 42 43.44 -1.44 2.0736 0.0477
cyan 86 83.46 2.54 6.4516 0.0773
green 39 40.1 -1.1 1.2100 0.0302
Total 167 167 0.1552
Chi-square value = 0.155
Degrees of freedom = no. of phenotypes – 1
Df = 3-1 = 2
Critical value = 5.99
Chi-square value of 0.155 is less than the critical value of 5.99. So we accept the null hypothesis.

According to the diagram how are the three components
of a nucleotide important to the structure of DNA?
Answer:
A nucleotide of DNA is made up of three parts: a nitrogenous base, a 5-carbon sugar, and a phosphate group. The four nitrogenous bases in DNA are adenine, cytosine, guanine, and thymine.
The phosphate group linked with deoxyribose sugar to make the framework for the nitrogenous bases. The phosphate group and sugar molecule make the DNA backbone and support it. These backbones hold nitrogenous bases and make a monomer of DNA. Nitrogenous bases make DNA stable and hold both backbones together. These bases also make DNA functional.
birth defects due to radiation are a concern also. why is a fetus especially at risk?
Of the babies that survive, however, few will have birth defects related to the exposure, regardless of how much radiation they were exposed to. Large radiation doses to the fetus during the more sensitive stages of development (between weeks 2 and 18 of pregnancy) can cause birth defects, especially to the brain.

g Neuron A and neuron B interact with neuron C. Neuron A will produce an IPSP of -2mV in neuron C; neuron B produce an EPSP of 3mV in neuron C. The resting membrane potential is -70mV and the threshold is -50mV. Neuron A fires 6 times rapidly at the same time that neuron B fires 4 times rapidly. What is the resulting membrane potential in neuron C
Answer:
-70 mV
Explanation:
Given that Neuron A and Neuron B interact with Neuron C
Neuron A produces ; - 2mV of IPSP and fires 6 times
Neuron B produces ; 3mV of EPSP and fires 4 times
Resting potential = - 70mV
threshold = - 50mV
The resulting membrane potential in neuron C
= -70 + 6(-2) + 4(3)
= -70 - 12 + 12 = -70 mV

1) Define biodiversity in your own words:
2) Why is biodiversity important?
Answer:
Explanation:
1.) Biodiversity is variety in an ecosystem and the living things inside of it. It means all the different species and creatures that live on the planet.
2.) Biodiversity is important because it provides vital ecosystem functions such as soil fertilization, nutrient recycling, pest and disease regulation, erosion control, and crop and tree pollination. Each species ina n ecosystem has a role to play.
