21 Science 6 - CR Calculating the Density of Propane Use the mass and volume data to calculate the density of liquid propane to the nearest hundredth. Mass of propane = 4,300 g Volume of propane = 10,000 mL The density of liquid propane is g/mL. Intro​

Answers

Answer 1

Answer:

0.43g/mL

Explanation:

Density of a substance is its mass per unit volume. It can be calculated thus:

Density = mass/volume

According to the information provided on propane in this question;

Mass of propane = 4,300g

Volume of propane = 10,000mL

Density = 4300/10000

Density = 0.43g/mL

Hence, the density of propane is 0.43g/mL.

A group of geologists is about to start excavating a new area for fossils. The area they are working in is the side of a cliff. Describe two pieces of information they will most likely be able to discover about the fossils they will find.

Answers

Answer:

Forms of fossils and there arrangement with layer of rock.

Explanation:

The seashore is a significant place for the depositional work of waves and it's also one of the significant places for the erosion and weathering of rocks.  The presence of sedimentary rocks along the cliffs are essential for the discovery of fossils of plants and animals. Fossils of shells and other creatures that were of marine origin are mostly discovered near excavation sites. Fossil helps to prove the age of rocks and strata.

The genetic code is defined degenerate or even redundant because:
A. the same codon codes for different amino acids
B. an amino acid can be encoded by several codons
C is different in all organisms, except in monozygotic twins
D. the sequence of codons is not separated by intervals, but is continuous
E. the structure of the genes is constantly mutating

Answers

Answer:

B. an amino acid can be encoded by several codons

Explanation:

The genetic code refers to the set of rules that govern how the four nitrogenous bases (A,U,G,C) is arranged to form amino acids. The genetic code is a collection of all the CODONS formed. There are different characteristics of the genetic code and one of them is its REDUNDANCY.

Since there are 4 nitrogenous bases combined in three's to form a codon i.e. 4³, there are 64 possible codons that could form 20 maximum amino acids. This means that there are more codons in relation to amino acids. Hence, more than one codon can encode an amino acid, and this is referred to as REDUNDANCY of the genetic code.

For example, LEUCINE amino acid is encoded by 6 codons as follows: UUA, UUG, CUU, CUC, CUA, CUG.

The following statement is incorrect as stated "Pesticides create pesticide resistance in mosquitoes." Rewrite this sentence so that it is a more accurate statement of what actually occurs when pesticides are used. Why is this concept important to know in trying to control outbreaks of mosquito transmitted diseases such as eastern equine encephalitis (also known as Triple E)?

Answers

Answer:

Mosquitoes usually become resistant to pyrethroids through the mutation of a sodium channel gene that controls the movement of ions across cell membranes. Mutations in a single gene are enough to make mosquitoes almost completely resistant to the level of pyrethroids used in insecticides.

Which of the cardiac cell characteristics describes the
ability to initiate an electrical impulse?

Answers

Answer:

The correct answer is: automaticity.

Explanation:

Cardiac muscle has several properties. These properties are: automaticity (given by the pacemaker cells), conductivity (meaning that each cardiac cell can transmit the electrical impulse to the next cardiac cells), contractility (like other types of muscles, cardiac muscle cells can contract), and irritability (each cell can contract on its own without the external stimuli).

Cardiac pacemaker cells are the ones with the capacity to initiate the electrical impulse by creating rhythmic impulses called action potentials, and thus directly regulating heart rate.

Pacemaker cells are located in the sinoatrial (SA) node, in the upper portion of the right atrial wall. In these cells, depolarization of the cardiac muscle begins, and the electrical impulse generated by it is transmitted to the atrioventricular (AV) node, the His bundle and then the Purkinje fibers - this order of events is necessary for the correct contraction of the heart to occur. All of these structures are part of the Conduction System of the heart.

Lactase is an enzyme that is produced in the lining of the intestines. This enzyme helps the body speed up the
breakdown of carbohydrates that are found in dairy products, such as milk, yogurt, and cheese.
Which general function does lactase perform?

Answers

Answer:

Regulation of cell processes

Explanation:

Lactase is an enzyme that helps in the breaking down of disaccharide sugar, lactose, found in many foods. It does it by converting the lactose into its component reducing sugars - glucose and galactose. This enzyme is produced by some special cells lining the intestinal walls of humans and forms a kind of chemical barrier known as brush border where foods must pass through before being absorbed. By so doing, foods are screened for the presence of lactose and any lactose is broken down before the foods are given a pass.

Which R group would most likely be found in a hydrophobic area of the tertiary structure of a globular protein?

Answers

Answer:

CH2-Aromatic ring

Explanation:

Amino acids with aromatic R groups are relatively hydrophobic and therefore don't interact with water molecules surrounding the protein. Tryptophan (Trp), phenylalanine (Phe) and tyrosine (Tyr) are amino acids with aromatic R groups. Since these amino acids are relatively nonpolar or hydrophobic, they participate in hydrophobic interactions that are strong when there are several residues with aromatic R groups which are stacked on one another. In this regard, it is also important to highlight that Tyr and Trp are more polar than Phe due to the hydroxyl (OH-) group in Tyr and the nitrogen in the Trp ring.

Given the latitudinal differences in sunlight intensity, how might you expect the carrying capacity of a plant species found at the equator to compare with that of a plant species found at high latitudes? Explain your answer

Answers

Answer:

The carrying capacity of a plant species expect in the equator is higher as compared to the carrying capacity at high Latitudes. This is due to the equator the plants have more light available, so the ecosystem can give them better conditions to survive and reproduce. Remembering that the carrying capacity is the largest population size an ecosystem can support without degrading itself, in the equator would be higher as it can have better conditions of light, so they would survive and reproduce more and the largest population the ecosystem could support would be higher.

The predominant forms of actin inside a cell are ATP-G-actin and ADP-F actin. What would be the consequence for actin filament assembly/disassembly if a mutation prevented actin's ability to bind ATP

Answers

Answer:

If actin is unable to bind to the ATP molecule, it will not be able to assemble into its two dominant forms.

Explanation:

As shown in the question above, the two predominant forms of actin are ATP-G-actin and ADP-F actin. As we can see, the formation of these two molecules involves the presence of an ATP molecule, in which case, the concentration of actin inside an organism depends totally on the capacity of the actin to be able to bind to an ATP molecule. If there is a mutation that prevents this binding from occurring, actin will not be able to form its two dominant forms, which will harm the presence of actin in the body.
