3.How have scientists' ideas of human evolution changed over time
Please Hurry
Answer:
They once thought that humans came from monkeys and apes but now they think they come from a ancient ancestor not from the monkey or ape family.
Explanation:
A human general manner of life, including what it consumes, how it grows, and where it may dwell, might change throughout time as a result of genetic change.
What is human evolution?New genetic variations in early ancestor populations favored new capabilities for environmental adaptation, which then in turn altered the human way of life and facilitated human development.
It is generally accepted that the development of modern humans from our hominid ancestors involves four main stages in evolution, developing terrestriality, bipedalism, a huge brain (encephalization), and civilization.
They more than likely came from Africa within the last 200,000 years, an ancient form of human called Homo erectus
Therefore, Homo erectus, meaning means "upright man" in Latin, is most likely the most recent common ancestor of today's humans,

Afforesting is a positive effort in curbing the over use and destruction of natural forests
Answer:
Explanation:
Afforestation simply refers to a campaign in favor of tree planting, against tree cutting in reserves or vegetation and the overall protection of the Forest reserve. Afforestation in the direct opposite of deforestation which is act of cutting down and destruction of forest trees. Trees are important part of our natural environment which plays economic, biological and chemical roles in the lives of the masses. Most notably, forest trees acts as carbon sink which in turn reduces depletion of the ozone layer. Even though their are economic derivatives in the cutting selling of forest planks for various purposes, tree planting culture must be legislated in other to avoid excessive use of forest reserves.

For every one bond created _ water molecule must be removed
Answer:4
Explanation:
For every bond created, four water molecules must be removed. Bonds break and join when molecules are formed.
What are chemical bonds?Different types of chemical bonds are present between different types of compounds, these bonds store energy and when the chemical reaction happens the reactance reacts they broke the bonds from the energy and create new compounds.
It takes a lot of heat to raise the temperature of liquid water, and an exceptional amount of heat to evaporate a given volume of water because hydrogen bonds need to be broken for the molecules to escape as gases.
Hydrogen bonds release water when they join or break. These bonds are formed in water and other compounds like DNA bases.
Therefore, four water molecules must be eliminated for every new link that is formed. When molecules are produced, bonds are broken and joined.

Controlled variable: Variables that are controlled and have no influence on the results of the experiment. These variables do not affect the change in the dependent variable values.
These variables must be the same for all the subjects or groups (control and experimental). In the case of plants, controlled variables are probably those needed by the plants to correct development.
All plants should be exposed to the same period of light-time and the same temperature. Also, the substrate or soil where the plants are growing should be the same.

"Explain what accounts for such a large amount of genetic variation within the human population?"
Answer:
humans are adapted to a wide range of environments, and genetic variation leads to phenotypic variation
Explanation:
It has been shown that the average genetic variation between human individuals is about 0.1% (i.e., one base pair out of every 1,0000 are different between any two individuals). This value seems low, but it is huge when we consider that the current estimate for the world population is 7,800,000,000 people. The phenotype is the result of the interaction between genotype and environment. Genetic variation is the raw material that enables some individuals to adapt to different environments. As species, humans have a high genetic diversity in order to develop a wide range of phenotypes well adapted to different environmental conditions.
Please help In a neutral atom, what two subatomic particles must be equal to have the overall charge of the atom be
neutral?
Answer:
The proton and electrons must be equal.
Explanation:
A neutral atom is an atom with a 0 charge. Protons have a positive charge and electrons have a negative charge, so adding them together would be 0. For example, one proton and one electron would be -1+1=0.
In general, which trophic level has the MOST energy available to it? a Producer b Primary Consumer c Secondary Consumer d Tertiary Consumer
Answer:
A producer
Explanation:
The trophic level which has the most amount of energy is the producer. Thus, the correct option is A.
What is a trophic level?The trophic level of an organism is the position which it occupies in a food web. A food chain is a succession of organisms which eat other small and simple organisms and may, in turn, be eaten up themselves or by higher organisms. The trophic level of an organism is the number of steps which it is from the start of the chain.
The food chain follows 10% energy law, where 10% of the energy is transferred to the next trophic level, this decrease with every trophic level limits the number of trophic levels in a food chain. The maximum energy is present in producers which perform photosynthesis.
Therefore, the correct option is A.

Relative dating and absolute dating are two different methods for finding the age of a rock. Name one advantage of each method and one disadvantage of each.
Please help! This is due in two hours.
Answer: The full explanation below.
Explanation: The advantage of Relative dating is it can tell if a rock is older or younger that a certain object where the age is also not certain making it easier to tell when the other object was from, however it dose not give an exact age of the rock. Absolute dating is different because it gives you the exact age of the rock, but does not aid in find the age of any artifacts that can be found around it. Hope this helps! :D
Absolute dating establishes the exact age of a historical relic, whereas relative dating determines the order of age of several samples. Absolute dating is therefore a quantitative measurement, whereas relative dating is a qualitative measurement.
What is dating?To date ancient events, geologists commonly use radiometric dating methods, which are based on the natural radioactive decay of certain elements such as potassium and carbon.
Relative dating is used to order geological events and the rocks they leave behind. The limitation of relative dating of fossils is that it does not provide the absolute age of the preserved fossils.
Absolute dating methods take physical properties of an object and use them to calculate its age.
Despite the fact that scientists exercise extreme caution when dating objects, recent studies show that they still make mistakes.
Because of incorrect setup, the dates used with this method are incorrect. The dates may not be consistent over long periods of time.
Thus, above mentioned are some advantages as well as disadvantages of two types of radiometric dating.
