how did Luigi Galvani's accomplishments help benefit our world with discoveries about electricity?
Answer:
During a random experiment on November 6, 1787, Galvani discovered that a frog muscle could be made to contract by placing an iron wire to the muscle and a copper wire to the nerve. ... This discovery played a historical role in bioelectricity as it proved that electricity was not direct in its action.

How do T-cells work to recognize invading cells or molecules?
Answer:
Antigen-presenting cells show digested antigens to T cells through the MHC on their surface, which allows the T cell to “see” the antigen and recognize it as foreign. The connection between the MHC and the receptor on the T cell is the first signal necessary to activate the T cell to respond to a tumor and destroy it.

which of the following is true about the Earth’s layers? A The asthenosphere is the thickest of Earth’s layers. B All of the layers are liquid and extremely hot. C There is little to no pressure on the solid core. D The Earth’s core has two different parts.
Answer:
D
Explanation:
The Earth’s core has two different parts is true about the earth's layer.
What is Earths core?
The extremely hot and dense core of our planet is called the Earth's core. Underneath the chilly, brittle crust and the largely solid mantle is the ball-shaped core.
Earth was a homogeneous ball of hot rock when it first formed roughly 4.5 billion years ago. The ball heated up even more due to radioactive decay and heat left over after planetary formation (the collision, accretion, and compression of space rocks).
After roughly 500 million years, our young planet's temperature reached 1,538° Celsius (2,800° Fahrenheit), the temperature at which iron melts. The iron age refers to this crucial period in Earth's history.
Therefore, The Earth’s core has two different parts is true about the earth's layer.

What conclusions can be drawn from the objects that Leeuwenhoek and Hooke observed in
their microscopes
Answer:
Antony van Leeuwenhoek1 (Fig. 1) found great joy in God’s smallest creatures. He first discovered protozoans in his youth. The Dutch haberdasher retained a child-like joy of discovery from his youth until his death at age 90. He lived to see tiny microbes though his homemade microscopes. He loved to grind and focus a new lens in order to see the unseen world. Leeuwenhoek spent countless hours grinding tiny lenses and looking through them. This Christian lay biologist even used candlelight to see specimens at night. For Leeuwenhoek, the amazing diversity of tiny life forms revealed under his homemade microscopes glorified God as much as looking at stars through a telescope. Leeuwenhoek was born in South Holland in 1632. As a young adult, he became a cloth merchant (also called a draper, or haberdasher). In 1668, he started his biological study as a hobby after seeing beautiful microscopic pictures while making a visit to London. After years of careful study, Leeuwenhoek (Fig. 2) made the microscope famous. In his lifetime, he became the father of microbiology and opened mankind to the world of microorganisms.

Explanation: Substances that were produced inside the cell that have to get out of the cell have to go through the cell membrane, because the cell membrane is the structure of cell.
how many monkeys would have to live in a 3/4sq.km. area to have the same population density as the carabao?
Answer: 20 monkeys
Explanation:
Question is lacking a very important detail which is the population density of monkeys in the Carabao.
I found that out to be 26.7 monkeys per sq.km
Population density = Number of monkeys / Area
With the population density known to be 26.7 monkeys per sq.km and the area known to be ³/₄ sq. km, the number of monkeys is;
26.7 = No. of monkeys/ ³/₄
No. of monkeys = 26.7 * ³/₄
No. of monkeys = 20
Jellyfish live in salt water. They have organs (and cell organelles) that pump the salt out of their bodies. The jellyfish body is actually filled with fresh water. Animals like sea turtles and whales eat them even though there are few or no calories in a jellyfish. Use your understanding of osmosis to explain this.
Answer:

Explanation:
Answer:
The animals like sea turtles probably eat the jellyfish because they enjoy the flesh of the jellyfish, not the content of it inside.

Which type of mutation results in a frameshift mutation? Check all that apply.
substitution
insertion
deletion
point mutation
Which type of mutation adds one or more base pairs?
insertion
substitution
deletion
Insertion-deletion type of mutation results in a frameshift mutation changing the amino acid code for protein, hence options A and B are correct.
What is frameshift mutation?A frameshift mutation is produced via insertion and deletion. "indel" mutations, which stand for insertion or deletion mutations, result in frameshift mutations.
The way the DNA is read is altered by these changes. The nucleotides that follow in a DNA sequence can all be affected by a frameshift mutation, making them more likely to have severe effects.
A frameshift mutation is brought on by insertion and deletion, mutations from insertional or deletional mutations result in frameshift mutations.
Therefore, frameshift mutations happen when one or more nucleotides are added or removed, provided that the total number of nucleotides added or subtracted does not exceed three, disrupting the normal sequence of codons, hence options A and B are correct.
