The following chemical equation shows the combustion of ethane. Balance the equation by filling in the coefficients.
Answer:
2 C2H6 + 4 O2 → 2 C + 2 CO2 + 6 H2O
Explanation:
2 C2H6 + 4 O2 → 2 CO2 + 6 H2O is the balance equation for the combustion of ethane. In the question, the equation for combustion of methane is unbalanced i. e. C2H6 + O2 → CO2 + H2O so by putting coefficient 2 in front of ethane, 4 in front of oxygen, 2 in front of carbondioxide and 6 in front of water which can balance the unbalanced equation for combustion of ethane

Which statement best explains the ideas of phyletic gradualism and punctuated equilibrium?
A. Phyletic gradualism isn't supported by the fossil record, but punctuated equilibrium is
B. Phyletic gradualism states that many species evolve rapidly at specific points in time, and punctuated equilibrium states that speciation occurs constantly over time
C. Phyletic gradualism states that speciation occurs constantly over time, and punctuated equilibrium states that many species evolve rapidly at specific points in time
D. Phyletic gradualism is supported by the fossil record, but punctuated equilibrium isn't
A. Phyletic gradualism isn't supported by the fossil record, but punctuated equilibrium is
Punctuated equilibrium and phyletic gradualism are two opposing evolutionary tendencies that can be seen in the geological record. Species in punctuated equilibrium tend to demonstrate morphological stasis between rapid speciation episodes, whereas species in phyletic gradualism change more frequently. "Phyletic gradualism isn't supported by the fossil record, but punctuated equilibrium is," says the statement that best summarizes the ideas of phyletic gradualism and punctuated equilibrium.

A person with a Doctorial Degree in Entomology and a Certificate in Forensic Entomology. Hence option D is correct.
What is Entomology ?Entomology is defined as the investigation of insects and how they interact with people, the environment, and other living things. Entomology is employed extensively in a wide range of fields, including evolutionary biology and medical research, in addition to studying the anatomy and physiology of insects. It aids agricultural entomologists in their research on biodiversity as well as in the protection of priceless resources from insect pests.
Forensic entomology is defined as the study of arthropods, particularly insects, connected to criminal activity and other judicial issues. An essential tool in the examination of homicide, self harm, and other violent crimes is forensic entomology. When properly gathered and examined by skilled forensic investigators, insect evidence found on a victim's corpse can provide important information.
Thus, a person with a Doctorial Degree in Entomology and a Certificate in Forensic Entomology. Hence option D is correct.

The phylogenetic trees are also known as CLADOGRAMS.
A phylogenetic tree is a diagram that shows evolutionary relationships between different species/taxa from a common ancestor to its descendants.A cladogram is a graphic representation that exhibits hypothetical phylogenetic relationships between groups of organisms/species/taxa.In a cladogram, groups of organisms/species/taxa are organized into clades, which share different traits.In a cladogram, a node denotes the common ancestor of a given clade.The Linnaean system of classification consists of grouping organisms/species according to their physical similarities, thereby it is not an evolutionary system of classification.
In conclusion, phylogenetic trees are also known as CLADOGRAMS.

Food webs in ecosystems become very complicated very fast. Explain why.
Answer:
Food webs are more complex than food chains, yet equally as useful in understanding the processes of ecological communities. A food web shows the flow of nutrients between different types of organisms which can help us understand the energy transfer as described before.
Explanation:
Food webs in an ecosystem involves the combination of two or more food
chains. This involves all the relationship an organism has with the others.
This makes the food web complex.
Food webs have different types of organisms present which ranges from
plants which are regarded as the primary producers to animals such as Lion
which can be regarded as a Secondary/tertiary consumer in the ecosystem.
The occasional change in the geography and seasons in the ecosystem
also makes it very complex as some animals exhibit different traits when
subjected to certain conditions. This makes analysis of energy flow and relationship sketchy to determine.

Perhaps no one cares more about being able to see in the ocean than do divers. The Cayman Islands, Bonaire and the Bahamas are all popular dive destinations due to both submarine features, such as coral reefs, and water clarity. Under the best of circumstances, visibility in these locations is between 50 ft (15 m) to 150 ft (45 m). Based on this, and what you have learned about sound, write a paragraph describing those ways in which humans and marine organisms use sound for some underwater tasks and light for others.
Answer:
Humans and marine organisms use sound finding depth of the ocean and objects.
Explanation:
Humans and marine organisms use sound for some underwater tasks such as finding depth of the ocean and objects. Human use sonar which is a device used to explore the ocean and animals use echolocation to find food and identify objects that comes in their way. Sonar is present in submarine uses sound waves to detect objects that comes in their way so both humans and marine organisms use sounds.

Which of the following is most likely true of a protein that cotransports glucose and sodium ions into the intestinal cells of an animal?
A) Sodium and glucose bind to the same site on the cotransporter.
B) Transport of glucose against its concentration gradient provides energy for uptake of sodium ions against the electrochemical gradient.
C) Sodium ions can be transported whether or not glucose is present outside the cell, but glucose transport requires cotransport of sodium ions.
D) Transport of sodium ions down their electrochemical gradient facilitates the transport of glucose against its concentration gradient.
E) Following transport of sodium ions into the cell, the cotransporter can also transport potassium ions out of the cell.
Answer:
D) Transport of sodium ions down their electrochemical gradient facilitates the transport of glucose against its concentration gradient.
Explanation:
Active transport refers to the movement of molecules across biological membranes against a concentration gradient. Active transport can be divided into 1-primary active transport, which requires energy from the hydrolysis of adenosine triphosphate (ATP); and 2-secondary active transport, which requires an electrochemical gradient generated by pumping ions in/out of the cell. The case above described represent a type of secondary transport active because the movement of sodium (Na) ions is used as energy source to move glucose molecules against their concentration gradient.
Answer: Transport of sodium ions down their electrochemical gradients facilitates the transport of glucose against its concentration gradient.
The role of the RNA-induced silencing complex (RISC) in RNA interference is to cleave tRNAs to slow the rate of translation. disrupt gene expression by cleaving mRNAs that are complementary to the guide strand of the RNA duplex that was introduced. cleave the introduced RNA duplex. disrupt gene expression by interfering with mRNA export to the cytoplasm. create a passenger strand to bind to the mRNA and keep the mRNA from being translated.
Answer:
disrupt gene expression by cleaving mRNAs that are complementary to the guide strand of the RNA duplex that was introduced
Explanation:
The RNA-induced silencing complex (RISC) is a ribonucleoprotein complex composed of proteins that associate with regulatory small non-coding RNAs (sncRNAs) such as, for example, microRNAs (miRNAs) and small interfering RNAs (siRNAs) in order to regulate gene expression by the RNA interference (RNAi) pathway. These sncRNAs (around 18-30 nucleotides in length) are complementary or nearly complementary to messenger RNAs, thereby they can bind to target mRNA sequences in order to trigger RNAi via mRNA degradation, translational repression, etc. The core component of the RISC complex is an evolutionary conserved Argonaute (Ago) protein that cleaves target mRNAs.

(iv) Measles. Mumps, Diphtheria Polio odd one
Answer: The odd one one is diphtheria
Explanation:
There are very minute living organisms that are able to cause different diseases to human which are found in our environment. These are known are microorganisms. They include:
--> viruses
--> bacteria
--> fungi
These microorganisms are able to establish an INFECTION in its human host when it's able fight and overcome the body defence mechanism of the host.
Diphtheria is the odd one because it's an infection which is caused by BACTERIA organism while other options while includes measles, mumps and polio are caused by VIRUS microorganisms.
BACTERIA are the larger microorganisms with a very simple cell structure where the nucleus is not enclosed within a membrane. While VIRUS are the simplest and smallest microorganisms which do not have a cell structure.
Diphtheria is an infection caused by the bacteria microorganism known as the Corynebacterium diphtheriae. These bacteria are able to produce toxins which is its virulent factor that are poisonous to its host.
Measles is an infection caused by paramyxovirus.
Mumps is an infection caused by mumps virus
Polio is an infection caused by picornavirus.
Therefore, Diphtheria infection is the odd one out.
