you discover that an atom of an unknown element had 54 protons. identify the element and explain how you know the identity is correct. explain whether the unknown element is more or less reactive than an atom of an element that has 30 protons. identify an element that would have very similar chemical properties (as element 54) to the unknown element and explain why its chemical properties would be similar.

Answers

Answer 1

Answer: Xenon

Explanation:

if you look on the periodic table of elements, youll notice that the only element with 54 protons is Xenon. Hope this helps!!

Answer 2

Protons are the positive charged subatomic particle that lies with the neutron in the nucleus of the atom.

The unknown element with 54 protons will be Xenon.

It is because Xenon is the only element in the periodic table having 54 protons. Element has the same number of protons and electrons therefore Xenon is the element that will have 54 protons.

It belongs to the noble gas group because the outer shell is a filled valence shell that is stable and less reactive compared to other elements.

Therefore it will be less reactive compared to the element having 30 protons.

The elements having similar properties as Xenon will be helium, neon, argon etc because they have the same group in the periodic table.

Answer:

This is the sample answer from edmentum/plato so paraphrase it:

Scientists once believed that all theropods were carnivores. However, recent research showed that some theropods evolved to eat plants. The fossil indicates that the new species of dinosaurs evolved to eat plants earlier than some of the other theropods. So, this new species may help scientists piece together an evolutionary lineage of theropods that ate plants.

I want an essay on the benefits of plants. Serious answers only.

Answers

Answer: I highly suggest that you reword this but here it is...

Plants are beneficial to the lives of many species on Earth. They provide us with oxygen, while also reducing the amount of carbon dioxide in the atmosphere.

Plant go through a process called "photosynthesis." This process allows them to take in carbon dioxide, water, and sunlight, and omit oxygen and glucose. Without plants, this process would only occur in microorganisms. By themselves, microorganisms do not have enough numbers and power to be able to provide enough oxygen for the rest of the species on the planet. All species that rely on oxygen would eventually perish.

Plants also prevent erosion. With their roots, plants hold down soil and stop the soil from moving. They provide structure and strength to the loose soil. If plants were not there to hold down soil, it would be entirely up to humans to provide structure in the soil.

Finally, plants are important to us because they provide us with a food source.  Humans use plants as a major source of energy. We eat plants, and mass produce them to feed ourselves. Plants are also a major food source for other animals that we rely for food. Animals that we eat get there energy from plants. If we wiped out the complete bottom part of the food chain, none of the other animals would survive.

Overall, plants are beneficial to us in many ways. They provide us with energy, stop erosion, and give us oxygen. Without plants, it would be impossible for humans to survive, and we would eventually perish.

Plants are beneficial to us as humans and animals in a number of ways.

Firstly, plants are the major source of food in the ecosystem. Every food chain starts with one plant or the other.

Secondly, oxygen. Plants help in providing us with more oxygen as they absorb Carbon dioxide from the surrounding atmosphere release oxygen. In my opinion this is the most important benefit of plants... as without them the level of carbon dioxide will increase in the atmosphere leading to a shortage of oxygen and eventual death of oxygen dependent organisms.

Plants also help take care of our environment. By preventing landslides and erosion in areas with heavy rainfall and winds as they cover the ground.

Plants also serve as habitats to organisms.

10. before replication begins, the strands of DNA are separated and used as templates for the new strands. the replication process creates 2 identical double helixes, each has 1 new strand and 1 old one.

11. without dna replication, damaged cells could not be replaced/repaired and cells need dna, cells would become mutated without dna replication.

12. mutations are rare because dna polymerase proofreads the strands but if the process occurred incorrectly and was not corrected by the polymerase, the cell would become mutated and could be really harmful.

hope this helped!
11.) each of the newly replicated helics is formed from a semi-conservative parent strand and one daughter strand

12.) because it creates the next copy of DNA that have to into one of the two daughter cells when a cell divides. Without it each cell lacks enough hereditary fabric to give instructions for crating proteins vital for bodily purposes.

13.) proteins might not function normally or at all. They can cause mutations like disorders or cancer.

Summarize photosynthesis and describe how it is part of the carbon cycle

Answers

Photosynthesis is when plants take in carbon dioxide and create glucose and oxygen. It is apart of the carbon cycle because it removes carbon from the air and turns it into oxygen.
Photosynthesis is the action of plants taking in sunlight to make their food. Just like us humanos make our own food they do the same thing when they get sunlight. This is part of the carbon cycle because during photosynthesis plants absorb sunlight and Carbon dioxide and in the end and let out oxygen.

Adaptations are special features that allow a plant or animal to live in a particular place or habitat. These adaptations might make it very difficult for the plant to survive in a different place. This explains why certain plants are found in one area, but not in another.

how are plant cells and human cells the same?
a. they can produce their own oxygen.
b. they make their own food from sunlight.
c. they can receive nutrients through the cell wall.
d. they use mitochondria to release energy from sugars.

Answers

A. They can produce their own oxygen

Plant cells and human cells are similar in the sense that they both use mitochondria to release energy from sugars.

Plant cells and human cells are two distinct kind of cells. Plant cells are autotrophic meaning that they can synthesize their own food using energy from sunlight but human cells are heterotrophic meaning that they depend on other organisms for food.

Despite this huge difference between plant and human cells, they still possess some similarities. One major similarity between plant and animal cells is that they both possess MITOCHONDRIA and use it to undergo cellular respiration.

Cellular respiration is a process that breaks down organic substances like sugars to synthesize ENERGY (ATP). This process occurs in the MITOCHONDRIA of both plant and animal cells.

Therefore, the fact that both plant and human cells use mitochondria to obtain energy is a similarity between them.
