Answer:
The Atmosphere
Explanation:
1816 was a year without summer because the billions of tons of ash that was spewed blocked radiation preventing it from reaching the surface of the earth.
A volcano is a break in the crust of planetary bodies like Earth that allows gasses, volcanic ash, and hot lava to escape. Volcanos are one of the major factors that cause climate changes on Earth mostly because of their cooling effect.
The ash, gasses and lava usually escape to the atmospheric layer of the earth with their cooling effect. And they cool the earth by blocking incoming solar radiation. This can go on for months or years depending on the components and severity of the eruption and can lead to "a year without summer" as witnessed in 1816.
what is known as photosynthesis
Photosynthesis is the process used by plants,Algae and certain bacteria to harness energy from sunlight and turn it into chemical energy.
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:
thanks
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.

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.

The correct answer is option A.
What are fossils?A fossil is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood, oil, coal, and DNA remnantsAccording to the question, all the options are relatable to the good fossils index except option A.
The fossils can be found anywhere on the earth, not at a specific location.

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

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.

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.
