1. How many pounds of biological material is below that soil surface?
Answer:
The amount of organic matter in mineral (sand, loam or clay) soils ranges from very low being 1% by weight, to average being 2 to 4%, and high being greater than 5%. There are also “muck” or organic or peat based soils that are 30 to 40% organic matter. The general consensus is the more soil organic matter the better. approximately 45%
Soil Composition
The basic components of soil are minerals, organic matter, water and air. The typical soil consists of approximately 45% mineral, 5% organic matter, 20-30% water, and 20-30% air. These percentages are only generalizations at best.
Explanation:
If a rock has a mass of 42 grams and a volume of 6 ml, what is its density?
Steps:
m = V × ρ
= 6 milliliter × 42 gram/cubic meter
= 6.0E-6 cubic meter × 42 gram/cubic meter
= 0.000252 gram
= 2.52E-7 kilogram

The finches that darwin studied differed in the shape of their beaks. according to darwin, which of these best describes these finches?
Answer:
C
Explanation:
A. no... the finches were living in different environments making them become less similar over time.
B. no... the Galapagos are long way from Africa... not possible
C. yes... This is true ... the size and shape of the beaks makes a big difference in the type of food the finches could eat. Seed types would change as climate change and finches would with the best beak size for the food available would survive.
D. no very unlikely. DNA Evidence show that the finches were from one common ancestor
The finches that Darwin studied differed in the shape of their beaks. According to darwin it become adapted to eating different foods.
Support your answer?The size and shape of the beaks make a big difference in the type of food the finches could eat.
Seed types would change with climate change and finches would with the best beak size for the food available to survive.
Thus, option "C" is correct whereas another option is very unlikely DNA Evidence shows that the finches were from one common ancestor.

His two principles were "use and disuse" and "inheritance of acquired characteristics." The latter is what the statement is referring to.
Answer:
Lamarck
In the case of a giraffe, Lamarck believed that giraffes once had short necks that got progressively longer as members of each subsequent generation stretched their necks as long as they could. In doing so, Lamarck believed that each generation would grow slightly longer necks and pass that trait onto their offspring.Jan. 16, 2018

What is Sunny weather?
Sunny weather is described as the type of weather where the sky is blue, the grass is bright, and there is a lot of sunlight that is usually warm when the sun comes out, so people in cold climates find it quite looks nice. People may not be so fond of this weather.
When it comes to absorbing heat on sunny days, the color of the fabric is more important than the length or material it is made of, when compared to a black shirt with short sleeves, a long sleeve white shirt can make you feel colder because of all the colors.
So when we wrap a black paper on something like jar it will get warmer as compared to other colour papers.
Thus, a jar placed in a sunny window will get warmest if it is wrapped loosely in Black paper. So, the correct option is (G)

What are cyanobacteria?Cyanobacteria is scientifically referred to as Cyanophyta and it can be defined as a group of single-celled, prokaryotic photosynthetic bacteria that live in aquatic habitats (water) and moist soils.
Additionally, this division of microorganisms are capable of manufacturing their own food through a process known as photosynthesis, which typically leads to a release of oxygen into the ecosystem.
In conclusion, Cyanobacteria are very important to the evolution and advancements of other life forms on planet Earth because they help in the production of oxygen through photosynthesis.

Police are investigating a series of murders in which the suspect is leaving little to no physical evidence, such as fingerprints or DNA. They cannot even establish an obvious link between victims. The only real evidence they have are strange pieces of typewritten poetry found tucked into the victims’ pockets. Who might the police call on to give valuable insight to help them identify the perpetrator and possible future victims? Forensic anthropologist Forensic entomologist Forensic pathologist Forensic psychiatrist
Answer:
Forensic anthropologist
Explanation:
Forensics is a branch of science that deals with the solving of crimes. According to this question, police are investigating a series of murders in which the suspect is leaving little to no physical evidence such as DNA or fingerprint. However, strange pieces of typewritten poetry was found tucked into the victims’ pockets as evidence.
Based on this evidence found, a FORENSIC ANTHROPOLOGIST is the person that can give valuable insight to help the police identify the perpetrator and possible future victims. This is because ANTHROPOLOGY is a social science subject that deals with past events, hence, forensic anthropologists will be able to work on the typewritten poetry.
