Answer:
Phanerogams are terrestrial plants and more advanced than the cryptogams. These are also called as flowering plants. Following are the characteristic features of phanerogams: They have well-differentiated plants i.e. the plant body is divided into distinct root, shoot, and leaves.
The spermatophytes, also known as phanerogams or phaenogams, comprise those plants that produce seeds, hence the alternative name seed plants. They are a subset of the embryophytes or land plants.
Which correctly lists three characteristics that are used to describe air? altitude, density, radiation O density, radiation, mass Omass, pressure, density Opressure, altitude, radiation
Answer:
The Correct Answer Is C
Explanation:
All Three Aspects are related to Air.
Air has mass, applies pressure, and takes up space. Therefore, option (C) describes the characteristics of air.
What is air?Air has particular qualities or features and is a mixture of gases, water vapor, and other elements. Gases make up air, which has mass, pressure, and weight as well as the ability to be compressed and be affected by temperature.
Nearly all of the air is made up of the molecules of two separate elements, nitrogen and oxygen. Carbon dioxide and argon, in trace levels, make up the remainder. (Trace amounts of other gases, including neon, helium, and methane, are also present.)

Explain what you think would happen to an egg placed in salt water? Describe why this would occur.
Answer:
An egg placed in salt water will float!
Explanation:
In normal tap water, an egg will sink because it's density is greater than the density of water. But, when salt is added to the water, it's density becomes greater than the egg's density. The term used to describe this is "buoyancy."
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?
Choose what
Answer:
The correct answer would be - design and run some tests or experiments.
Explanation:
The scientific method is an orderly or step by step process that helps in developing the knowledge about a particular scientific process. This process involves having a purpose, observe the characteristics, making a hypothesis with a possible explanation, designing a test or experiment for the hypothesis, analyzing the result or data, and making a conclusion.
In this experiment, the purpose, and observation of the already formulated so the next step would be designing a test and run the test to find the result or data for further investigation.

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.
Would an atom with high electronegativity more likely react with an atom with high ionization energy or low ionization energy?? Why???
Answer:
a high ionization atom
Explanation:
Answer
It would be more likely to react with an atom with low ionization energy. Electronegativity refers to an atoms ability to attract electrons to it. If it has a high electronegativity, it has an easier time attracting electrons. This is important when it comes to forming bonds in which electrons are being shared (like in covalent bonds).
hope this answers your question! :)
Summarize the steps that occur in the process of chromosomal DNA replication. Please place the following steps in the proper order.
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.

Equipment required: A hair dryer, two glass beakers, glasses or glass jars, two thermometers, and enough water to fill one of the beakers or glasses.
Fill one beaker with tap water at room temperature and leave the other one empty. Place a thermometer in each beaker. Set the two beakers side-by-side and record the temperatures in each beaker. Using the hair dryer, blow hot air evenly for several minutes on the two beakers and monitor the temperatures in each beaker. How do the two beakers respond to the hot air?
Answer:
The temperature of the beaker with water should change very little compared with the beaker with just air, demonstrating that the heat capacity of water can resist changes in air temperature.
Explanation: EDMENTUM/PLATO ANSWER
The two beakers unequally respond to the hot air. This is because the beaker full of water has a heat holding capacity that can resist the alteration in the temperature when hot air is blown onto it.
What is Thermometer?A Thermometer may be defined as an instrument that can measure the temperature of a particular location significantly.
According to the question, the temperature of the beaker which is full of water changes very little as compared to the beaker which is empty.
Therefore, it is well described above.

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.
