Predict: Why aren't all organisms made of just one cell?
Why do cells divide, instead of simply growing larger?
The living beings that are comprised of more than one sort of cell are known as Multicellular Organisms.
Why organisms are made up of cells?These organelles are liable for an assortment of cell capacities, for example, acquiring supplements, creating energy, and making proteins. Unicellular living beings are comprised of just a single cell that completes each of the capacities required by the organic entity, while multicellular creatures utilize various cells to work.
Cells divide because:
Cells need to separate for your body to develop and for body tissue, for example, skin to restore itself ceaselessly.

1. The pollutants in our atmosphere have the ability to change the entire planet’s
2. is a theory that states that the increasing carbon dioxide in the atmosphere is causing the climate to warm up.
Answer:
Ans1 Not only does it contain the oxygen we need to live, but it also protects us from harmful ultraviolet solar radiation. It creates the pressure without which liquid water couldn't exist on our planet's surface. And it warms our planet and keeps temperatures habitable for our living Earth
Ans.2 The carbon dioxide theory states that, as the amount of carbon dioxide increases, the atmosphere becomes opaque over a larger frequency interval; the outgoing radiation is trapped more effectively near the Earth's surface and the temperature rises.

In 1953, Watson and Crick discovered the structure of DNA by examining data from many different experiments. How did using Chargaff’s data help Watson and Crick determine the structure of DNA ?
Answer: Chargaff's observation was an important clue to the A-T and G-C pairings that Watson and Crick eventually proposed. ... The structure of DNA suggested that the order of bases contains information. Because A is always paired with T and G with C, the order of bases on one strand determines the order on the other strand.
Explanation:
Chargaff’s data helped Watson and Crick determine the structure of DNA
through determining that it has a double helical structure.
Chargaff's rule states that a DNA consists of nitrogenous base pairs in which
the pairs have equal units and specific binding mate.
Adenine binds with Thymine Cytosine binds with Guanine.The base pairs present in the DNA makes its shape to be double helical.

describe the water cycle here on Earth and explain how it demonstrates the law of conservation of matter.
Answer:
Start with evaporation. Place a full cup of water in front of a sunny window. Use a marker to make a line at the beginning water level.
After evaporation we have condensation. When the water vapor reaches the sky it cools to form clouds.
Finally, a precipitation experiment. Again, fill a cup almost full with water.
Explanation:
Matter is conserved because atoms are conserved in physical and chemical processes. As complex as the water cycle is, water molecules are conserved and endlessly recycled in nature. Conservation of mass is a physical law that s never broken.

subject and object pronouns
Rishi and (I,me) have always shared an intimate relationship over the years.
Answer:
I
Explanation:
In English language, a subject can be defined as the person, thing, idea or place that performs an action.

A pronoun is one of the parts of speech and it can be defined as a word that replaces a noun in a sentence. Some examples of a pronoun are he, she, you, I, who, it, them, ours, etc.
Therefore, Rishi and I have always shared an intimate relationship over the years. Rishi is the subject while I is the object pronoun.

Food Availability, Places to live, and water availability are all ______ of an Ecosystem.
Answer:biotic factors
Explanation:
They are living
Food availability, places to live, and water availability are all Abiotic Factors of an Ecosystem.
What are Abiotic and Biotic components?Biotic and abiotic factors make up ecosystems in which biotic factors are living things within an ecosystem such as plants, animals and bacteria, while abiotic are non-living components such as water, soil and atmosphere.
An abiotic factor is a non-living part of an ecosystem that shapes its environment. In a terrestrial ecosystem, the abiotic factors are temperature, light, and water. In a marine ecosystem, the abiotic factors are salinity and ocean currents. Abiotic and biotic factors work together to form a unique ecosystem.
Biotic components are living things that have a direct or indirect effect on other organisms in the environment such as animals, and microorganisms and their waste materials.
Thus, food availability, places to live, and water availability are all Abiotic Factors of an Ecosystem.

Explanation:
2. All living things are made up of MULTIPLE cells, even the smallest creature has multiple cells, the cells are just smaller so that they all fit into that one creature. So the answer is that C: "Some living things are made up of only one cell", because all living things are made up of many, many cells
3. It would be Tissues, what gave it away would be that, not only is Q a long strip, which takes out Bacteria and Muscles, but then S takes out Root's which leaves Tissues. The answer is D: "Tissues", because the Q and S cross out all other answers
4. Their root system is the tissues, which work the most in plants, their tissues also help with eating, breathing, and even standing upright. The answer is D: "Tissues", it works the most for a lot of reasons
5. Connective, Muscular, Nervous, and Epithelial (which is not a part of the question) are all human tissues, so Meristem is not a human tissue, in fact, its a PLANT tissue, also known as Meristematic Cells. The answer is B: "Meristem", because it is a plant cell, not human.
