What is caused by the action of hot material rising and cool material sinking?
Answer: Heat transfer
Explanation:
Hot material such as hot air or liquid is more dense that cool material so it will rise. As it does so the cool material will sink towards the source of heat that is making the hotter materials hot and get heated as well which will enable it to rise and the whole cycle repeats.
This type of heat transfer is called Convection and it is very important to processes occurring on earth from basic things such as how water is heated in a kettle to how rainclouds are formed in the atmosphere.

You have a cup of beans in front of you with 20 white beans and 20 red beans. These beans represent the alleles for a simple Mendelian trait, where red is dominant (R) and white is recessive (r). The cup holds the alleles for an entire population (the gene pool). Note: You may substitute other everyday objects (such as candies, coins, or paper clips) for the beans, but be sure to designate which objects represent the dominant versus recessive alleles.
How many alleles of each type are present in your overall population?
Answer:
Dominant: 20, Recessive: 20
Explanation:
The case shown in the question above explores simple Mendelian traits, since it shows a population where individuals of the same species present the dominant allele (R- red) and the recessive allele (r- white). We can project, then, that this population has an allele balance, where it is possible to find 20 red beans, which have the dominant allele and 20 white beans, which present the recessive allele.

A. DnaA proteins bind to the origin of replication, resulting in the separation of the AT-rich region.
B. DNA helicase breaks the hydrogen bonds between the DNA strands, topoisomerases alleviate positive supercoiling, and single-strand binding proteins hold the parental strands apart.
C. Topoisomerases unravel the intertwined chromosomes, if necessary.
D. Primase synthesizes one RNA primer in the leading strand and many RNA primers in the lagging strand, and DNA polymerase III synthesizes the daughter strands of DNA.
E. DNA polymerase I removes the RNA primers and fills in that region with DNA, and DNA ligase covalently links Okazaki fragments together.
F. Replication continues until the two replication forks meet on the other side of the circular bacterial chromosome.
Answer:
The proper order is:
A. DnaA proteins bind to the origin of replication, resulting in the separation of the AT-rich region.
B. DNA helicase breaks the hydrogen bonds between the DNA strands, topoisomerases alleviate positive supercoiling, and single-strand binding proteins hold the parental strands apart.
C. Topoisomerases unravel the intertwined chromosomes, if necessary.
D. Primase synthesizes one RNA primer in the leading strand and many RNA primers in the lagging strand, and DNA polymerase III synthesizes the daughter strands of DNA.
E. DNA polymerase I removes the RNA primers and fills in that region with DNA, and DNA ligase covalently links Okazaki fragments together.
F. Replication continues until the two replication forks meet on the other side of the circular bacterial chromosome.
Explanation:
The process of DNA replication in prokaryotes starts at a point called ORIGIN OF REPLICATION. This site is where certain proteins recognize and bind to in order to kickstart the replication process. The following are orderly processes of DNA replication.
- DnaA proteins bind to the origin of replication, resulting in the separation of the AT-rich region.
- DNA helicase breaks the hydrogen bonds between the DNA strands to form two replication forks, topoisomerases prevent supercoiling of these separated DNA, and single-strand binding proteins hold the parental single strands apart, hence, making sure that they do not rewind again.
- In case DNA rewinds, topoisomerases unravel or disentangles the intertwined chromosomes, if necessary.
- DNA Primase synthesizes one RNA primer in the leading strand and many RNA primers in the lagging strand,which allows DNA polymerase III synthesize the daughter strands of DNA. Note that the synthesis of nucleotides on threading strand is continuous while nucleotides are synthesized in small fragments called OKAZAKI FRAGMENTS, on the lagging strand.
- DNA polymerase I removes the RNA primers and replaces with synthesized DNA in that region, and DNA ligase covalently links the Okazaki fragments (small fragments of DNA) together.
- Replication continues until the two replication forks meet on the other side of the circular bacterial chromosome.
Using the Scientific Method to Identify a Pathogen
The tests for these uncommon pathogens are similar to the ones that have already been performed for the common viruses, but in this case, you will try to identify the DNA or proteins of specific viruses that are not often seen in clinics or hospitals in that area of the country. Each region of the country has certain viral pathogens that are spread throughout the human population that live in that area. When one of these viruses spreads to a new area, we consider it to be "emerging" in this new population of people. Some detective work and deductions will be required. By applying the scientific method, you can focus and refine your list of possible viral pathogens to experimentally test for. You’ll begin your investigation by reviewing the patient’s history and symptoms and formulating a hypothesis for possible causative agents. Based on what you know of the scientific method, what would you like to do next?

Answer:
Rhizoids
Explanation:
Mosses, liverworts, and hornworts are three groups of a division of plants called BRYOPHYTA. These division of plants are referred to as "lower plants" because of their primitive features. They are non-vascular i.e they do not possess vascular conducting tissues e.g xylem, phloem etc.
In addition to this, bryophytes (mosses, liverworts, and hornworts) do not have true roots and leaves like other plants. Instead, they possess colorless root like projections called RHIZOIDS, which they use to anchor themselves to the substrate and absorb water.

Answer:
More mitochondria present in the heart as compared to other organs.
Explanation:
The distribution of mitochondria is not the same throughout the body. The organ which perform more hard work in the body have more number of mitochondria in the cell because the organ needs more energy for performing its function. Heart is the organ in the body that performs more hard work so there are 5000 mitochondria present in each cell of the heart.
The organ that contains the highest amount of mitochondria is the heart.
Cells are the simplest units of the living organism which are organised in various amounts to form tissue.
These cells contain organelles that brings about the normal functioning of the cell.
An example of the organelle is mitochondria.
The mitochondria is the power house of the cell which is located in organs that requires a lot of energy.
Example of such organs are:
