All living things are made of one or more organs? True or false
Answer: True
Explanation:
All living things are made of cells; the cell itself is the smallest fundamental unit of structure and function in living organisms. ... Organs are collections of tissues grouped together performing a common function. Organs are present not only in animals but also in plants.
How many combinations of A, C, G, and U exist? Include an equation
Answer:
64
Explanation:
4 ^ 3 because your first nucleotide can be any of the 4, same with your second, and same with the last nucleotide. 4^3 tells you there are 3 different positions that 4 different bases can be placed.
Hope this helps!
There are 64 possible combinations of nucleotides to form a given amino acid.
The genetic code to add an amino acid is the result of a triplet of nucleotides or codons. In consequence, there are 4^3 possible combinations of nucleotides in a codon.This number (64) gives us the number of different codons that can be found in the genetic code.In conclusion, there are 64 possible combinations of nucleotides to form a given amino acid.

What is one important difference between savannas and temperate grasslands? A. Savannas only rarely experience fires. B. Temperate grasslands are mostly treeless. C. Savannas are inhabited by grazing mammals. D. Temperate grasslands have nutrient-poor soil.
The one important difference between savannas and temperate grasslands
is that Temperate grasslands are mostly treeless.
Temperate grasslands have varying types of plants and animals in the
region. They have very few trees and are mainly dominated by grasses.
The temperate grasslands have lesser amount of rainfall than the
savannas.
The Savannas have different types of plants ranging from shrubs to
woody trees. The temperate grasslands have nutrients due to the
formation of organic matter from dead plants leaves and roots and aren't
generally regarded as having nutrient poor soil.

Describe the process of oxidation in terms of electrons AND energy.
Oxidation is described as the loss of electrons and energy by a molecule.
OXIDATION:Oxidation is a process whereby a molecule loses electrons (e-) or energy to become positively charged. Oxidation changes the oxidation number of the molecule involved depending on the number of electrons lost. Reduction is the opposite of oxidation, and it entails gain of electrons and energy by a molecule. Together, they are called oxidation-reduction or redox reaction.Learn more about oxidation at: https://brainly.com/question/3867774?referrer=searchResults

We need to recycle our waste because Earth is a closed system with respect to
matter, and new matter does not enter the environment. Agree or disagree
I disagree because although recycling is good, Earth firstly is not a closed system and new matter enters the environment all the time, such as comets.
In terms of matter, the Earth is often referred to as a closed system. In other words, the total amount of matter on Earth neither changes nor becomes more or less; Instead, it can take on different forms due to different processes. So, I am agree with this statement.
Although the Sun provides the world with continuous energy, most of the actual matter on Earth is recycled and used in various cycles. Recycling of waste is important because it enables us to recover useful materials and resources, reducing the need for mining new raw materials from the earth. Recycling helps us to reduce the environmental damage caused by the extraction and disposal of waste as well as the depletion of natural resources. It helps maintain long-term equilibrium inside a closed system of matter on Earth.

Using 3-5 sentences explain how human activties can affect climate change.
Answer:
Human activities can affect climate change because of just how much waste we produce. One huge example is our burning problem, which slowly strips away at the ozone layer that protects animals from heat and melting snow. Because of the ozone layer, the arctic has been protected for many years but now it's slowly disappearing, melting ice and killing animals who have not learned to survive in such hot weather. Another example is when humans cut down too many trees to sustain the environment; it often causes a massive lack in natural oxygen and unroots many homes of small critters and worms. In conclusion, humans can heavily affect climate change because of our ignorance and how we refuse to learn for the future.
