Prediction: Correlations can be used to help make predictions. If two variables have been known in the past to correlate, then we can assume they will continue to correlate in the future. We can use the value of one variable that is known now to predict the value that the other variable will take on in the future.
A positive correlation is one in which variables go up or down together, producing an uphill slope. ... Any type of correlation can be used to make a prediction. However, a correlation does not tell us about the underlying cause of a relationship.

Which of the following is NOT true about viruses?
A. Viruses have a protein coat.
B. Viruses have their own genetic material.
c. Viruses can reproduce on their own.
D. Viruses are classified by shape.
Answer:
C.
Explanation:
Viruses are classified by shapes. Lots of viruses are being created each day, and we have to name it by shape (just look up how the virus from China adopted its name). Viruses have coats of DNA to help it overgo the most extreme tempuratures. Viruses have to reproduce on a shape or surface to find a host. Viruses have to have a genetic material so the virus can evole and adapt to the most harshest of areas.
Viruses are defined as microscopic infectious agent, which requires a host to replicate. The viruses have genetic material, a protein coat, and are classified based on the phenotypic characters.
The option that is not correct about the virus is:
Option C. Viruses can reproduce on their own.
Viruses are microscopic entity that requires the host to replicate and reproduce. Some of the features of viruses are:
Viruses have a protein coat, which is known as a capsid. Capsid protects the genetic material of the virus. The genetic material of the virus can be DNA or RNA. The viruses incorporate their genetic material into the host cell to replicate and reproduce. The viruses are classified based on phenotypic characters such as genetic material, mode of replication, morphology, and disease-causing.
Therefore, option C is not true about viruses.

Transmembrane proteins span the width of the cell membranes. Four types of transmembrane proteins are shown in a section of cell membrane.
groene
Although these proteins have different specific functions, they all-
A-stop chemical reactions within the cell
B-synthesize molecules that signal other cells
C- help the cell interact with its external environment
D- remove large waste particles from the cytoplasm of the cell
Answer:
C. help the cell interact with its external environment
Explanation:
A transmembrane protein (TP) is a type of integral membrane protein that spans the entirety of the cell membrane. Many transmembrane proteins function as gateways to permit the transport of specific substances across the membrane.
Although transmembrane proteins have different specific functions, they always HELP the cell interact with its external environment.
Transmembrane proteins are a broad category of membrane proteins that act as carriers and/or transporters in order to allow the movement of specific substances across cell membranes.
After binding to their specific ligands, the three-dimensional (3D) shape of transmembrane proteins changes in order to allow the movement of molecules and ions through the cell membrane.
For example, aquaporins are a type of transmembrane protein that regulates the entry of water (H2O) molecules into and out of cells.
In conclusion, although transmembrane proteins have different specific functions, they always HELP the cell interact with its external environment.

Many processes occur in the digestive system .which process is best classified as a physical change
Answer:
This question lacks options, the options are:
A) Saliva converting the starch molecules in crackers into simple sugars
B) Digestive enzymes breaking down proteins into smaller fragments
C) bacteria converting lactose into simple sugars in the intestines
D) teeth grinding an almond into smaller pieces in the mouth
The answer is D
Explanation:
A physical change is a change that occurs to a substance without altering its chemical composition. A physical change involved a change in the substance's shape, texture, color, state etc. but not the chemical content of such substances.
In this question involving the processes that occur in digestion, a typical example of physical change is "teeth grinding an almond into smaller pieces in the mouth" because the teeth only changes the shape and texture of the almond. It does not affect the chemical composition of the almond fruit. This is also called mechanical digestion.
Note that, other options involving digestive enzymes breakdown are chemical changes because the enzymes breakdown the chemical components of each substance.
Answer: D
Explanation: because you are breaking down food in a physical change

Answer:
B. Egg and sperm cells must only have the number of chromosomes so that when they combine the number will equal 46.
Explanation:
The purpose of meiosis is to shuffle genetic information and cut the cellular chromosome number in half, from 46 chromosomes to 23 chromosomes. In this way, when an egg and sperm cell combine during fertilization, the resulting embryo will inherit the appropriate amount of unique genetic information from each parent.

The speed at which waves approach the shore depends on the shoreline features and the depth of the sea floor. When a wave reaches the shore, it releases a burst of energy that generates a current which runs parallel to the shoreline. What is this current called?
Answer:
Longshore current.
Explanation:
A wave is a disturbance which travels through a material medium without any permanent displacement of the particles of the medium. During the propagation of a wave, energy is transmitted from one point to another since waves flow with energy. The higher its speed of propagation, the higher the energy of the wave.
The energy released by the wave at shore produces a current which is referred to as a longshore current.
Answer:
It would be Longshore Current

How was the process used to construct the tree of life by Carl Woese different from the process used by Jill Banfield?
Answer and Explanation:
Carl Woese used ribosomal RNA genes to study the evolution of living beings. He used these genes because they are present in all organisms, and they all have the same function. The nucleotide sequences change very little, giving a real evolutive vision. Woese compared ribosomal genes among different living beings. The sharper the sequence variation is among two organisms, the bigger the evolutive divergence is. This divergence drowned in a phylogenetic tree shows three well-differentiated domains: Archea, Bacteria, and Eukarya. Jillian Banfield used genes from 16 ribosomal proteins from many different unknown microorganism species. She and her team used metagenomic methods that are the simultaneous analysis of multiple genomes belonging to many organisms in the same sample. These methods allowed detecting different organisms, even when these were neither previously observed nor lab-cultivated. The comparison among these new genomes with many others already known made a place for the construction of a new and more detailed tree of life where many new branches emerged from the three domains.As the human population increases, which challenge will most likely be addressed through biology?
○ mining more mineral resources
○ increasing food production

Are there any mammalian cells that would be a good source for dividing cells? What types of cells would most like NOT have cells undergoing division?
Answer:
Skin cells, bone cells
Explanation:
1. Skin cells are constantly being replaced, so it's likely they will be undergoing Mitosis.
2. Bones grow very slowly, and can last for years, which means that it's unlikely they will be undergoing mitosis.
There are a couple of mammalian cells that would be a good source for dividing cells. They include but not limited to:
The cells of the skinCells in the bone marrowThe cells of the skin adjacent to the environment are constantly being replaced by cell division due to death relating to environmental factors.
The cells in the bone marrow are also dividing constantly because old blood cells are constantly being replaced.
Some cells in the human body do not divide ordinarily, unless they are called upon to do so on special circumstances. For example, the cells of the heart stop dividing once the heart gets to a particular size. The cells enter the quiescent stage of the cell cycle and they are only called upon to divide in case an injury occur to the heart and it needs to repair itself.

Suppose a scientist must choose whether to publish a report in a newspaper or in a peer-reviewed journal. What is a benefit of publishing in the journal?
Answer/Explanation:
Because the journal is peer-reviewed, it means their report is assessed and critiqued by experts in the field. This means the data is more reliable and more likely to be trusted by other scientists in the field.
Additionally, the journal is likely to be specialized and used to accepting scientific reports, meaning they will have certain regulations and criteria for publishing.
Why does each human have two sets of 23 chromosomes? Where do those chromosome sets come from? How would your chromosomes compare to someone else’s chromosomes?
Answer:
This is because our chromosomes exist in matching pairs – with one chromosome of each pair being inherited from each biological parent. Every cell in the human body contains 23 pairs of such chromosomes; our diploid number is therefore 46, our 'haploid' number 23.
Explanation:
Humans have 23 pairs of chromosomes because 23 chromosomes come from the father and the other 23 come from the mother, and thus humans end up with 46 chromosomes. With 23 sets, you have two copies of each gene. This is what happens in normal situations. However, in some cases during cell division, there could be more or less that 46 chromosomes.
One set of 23 chromosomes is inherited from the biological mother (from the egg), and the other set is inherited from the biological father (from the sperm). Of the 23 pairs of chromosomes, the first 22 pairs are called "autosomes." The final pair is called the "sex chromosomes."
In a normal diploid cell, there are 24 *different* chromosomes out the total of 46: there are 22 pairs of identical autosomes and 2 non-identical sex chromosomes.
