Answer:
Embryotic stem cell research benefits our society with the possibility of it helping various diseases and it only requires a small number of cells. The negatives of stem cell research are the cost and ethical controversary. To start, stem cell research could help with diseases like Alzheimer's and certain cancers like Parkinson's. Also since cells replicate incredibly fast, procedures wouldn't need many cells depending on the case. Stem cell research can vary in costs from about $5000 to $20,000 which for many people is difficult because stem cells are very temporary in many cases. Many groups of people don't agree with stem cell research since human embryos are destroyed in the process of harvesting embryonic cells and it is "potential life".

Which of the following choices represents the approximate percentage of geologic time that humans have existed on Earth since its origin?
less than 1%
1.8%
11.8%
more than 25%
Answer:
less than 1%
Explanation:
The approximate percentage of the geologic time that humans have existed on the Earth since its origin is less than 1%.
The earth is about 4.6 billion years and much of its history has been without the present of human activities.
Hominis were the first human to appear on the surface of the earth. This was in the Miocene epoch which was about 6 million years ago. Compared to the age of the earth, this time lapse is very small and not up to 1%. Life first appeared on earth about 3.5billion years. Since then evolution has taken its due course to give what we have today.The Earth's tilt also causes the Sun's radiation to strike the _____ at different _____.
Answer:
hemispheres; angles
Explanation:
When a hemisphere—either northern or southern— is tilted toward the sun it has more hours of light compared to the hemisphere tilted away from the sun. Moreover, lower latitudes where the incoming solar radiation is more direct (angle closer to 90°) receive more radiation compared to higher latitudes where sunlight strikes at lower angles. The combined effect of more hours of daylight and more direct radiation in the hemisphere tilted toward the sun generates warmer temperatures compared to the hemisphere tilted away from the sun.

What would happen on a hot day if your brain did not receive input that your body was starting to heat up
Answer:
The body will overheat
Explanation:
If the brain of an individual does not receive input that the body was starting to heat up on a hot day, the setpoint temperature of the body would be exceeded and the body will overheat. If the condition persists for a while, the entire systems of the body may shut down due to overheating.
Normal homeostatic response requires that the brain (the control center) receives a message from the skin (the sensor) about a rise in the body's temperature. In turn, the brain will set mechanisms that will bring the body's temperature back to normal in motion, including vasodilation of the blood vessels in the skin to allow more blood into the skin which in turn causes more heat loss to the surrounding. Thus, an individual starts sweating and the evaporation of the sweat causes cooling and a return of the body to the setpoint temperature.

In chemiosmosis in mitochondria, protons flow from the intermembrane space into the matrix. In what direction do protons flow during chemiosmosis in chloroplasts
Answer:
Protons flow from the thylakoid space into the stroma of the chloroplast
Explanation:
Chemiosmosis is one of the two events that occur in oxidative phosphorylation (the other being electron transport chain). Chemiosmosis, which occurs to synthesize ATP in both cellular respiration and photosynthesis, is the process whereby protons (H+) move across a membrane via osmosis. In other words, chemiosmosis builds the proton gradient required to power ATP synthesis via the aid of an enzyme called ATP synthase.
In cellular respiration, chemiosmosis occurs when protons flow from the intermembrane space into the matrix while in PHOTOSYNTHESIS, cheniosmosis occurs when protons flow from the thylakoid space into the stroma of the chloroplast.
The flow of protons takes place from the thylakoid space into the stroma of the chloroplast during the chemiosmosis in chloroplasts.
What is chemiosmosis?It is one of the events, which takes place during oxidative phosphorylation. It generally takes place to produce ATP in both the process of photosynthesis and cellular respiration. In the process, the protons move across a membrane through osmosis.
It can also be stated that building of the proton gradient for the synthesis of ATP takes place by chemiosmosis with the help of an enzyme known as ATP synthase.
Chemiosmosis takes place when flow of protons takes place from the intermembrane space into the matrix during cellular respiration. While in photosynthesis, chemiosmosis takes place when flow of protons takes place to the stroma of the chloroplast from the thylakoid space.
Thus, in chloroplasts, chemiosmosis takes place when flow of protons takes place from the thylakoid space into the stroma.

Explanation:
I gave an extra so you had a couple of options!
There are many more words with the suffix "tion," such as evolution, reproduction, and regeneration, and here the evolution is possible through sexual reproduction, and the regeneration is a process in which new cells are grown.
What is the significance of reproduction in living things?In the living forms, both types of reproduction are seen, such as sexual reproduction and asexual reproduction, and in the case of sexual reproduction, there is variation among the offspring due to the crossing over and the recombination, whereas this is not seen in the case of asexual reproduction. Asexual reproduction is seen in plants and others, while the parents and offspring are similar.
Hence, there are many more words with the suffix "tion," such as evolution, reproduction, and regeneration, and here the evolution is possible through sexual reproduction, and the regeneration is a process in which new cells are grown.

It is an important process that every plant is needed to live
The appearance of the pink color was due to the movement of a. phenolphthalein molecules from low concentration to high concentration b. base molecules from high concentration through the membrane to low concentration c. water molecules through the membrane from high concentration to low concentration d. phenolphthalein molecules in the water from high concentration to low concentration
Answer:
b. base molecules from high concentration through the membrane to low concentration
Note: the complete question is found in the attachment below
Explanation:
The process which enabled the color change in the water and phenology mixture is known as diffusion.
Diffusion is the movement of molecules from regions of higher concentration to regions of lower concentration until equilibrium concentration is attained.
In the setup by the student, the concentration of the base molecules are higher in container than in the test tube. The vaporized molecules of the base therefore, moved through the membrane into the water and phenolphthalein mixture, resulting in the color change to pink in the mixture due to the reaction of the base and the phenolphthalein.

Based on this pedigree, what are the most likely genotypes of individuals I-1 and 1-2?
When entering the answer use AA, Aa, or aa.
Individual l-1 genotype=
Individual 1-2 genotype=
PLEASE HELP!
Answer:
I-1 genotype = AA or Aa
I-2 genotype = aa
Explanation:
The trait in question is autosomal and dominant. Let us assume that the trait is represented by the allele A, the alternative form would be a.
I-1 individual is affected for the disease, hence he is either true-breeding AA or heterozygous Aa.
I-2 individual is not affected for the disease, hence, she can only be aa. For an autosomal dominant trait, an individual is either affected or free from the trait. There is no chance of being a carrier. Heterozygous individuals are affected for the disease.
Therefore;
I-1 genotype = AA or Aa
I-2 genotype = aa
