Can someone explain question 4?

Answer:

Impact of double-stranded mRNA before translation would inhibit the binding of tRNA to mRNA ti synthesize protein.

Explanation:

The mRNA is a molecule that, with the exception of viruses with double-stranded RNA, has only one chain. It is in charge of conducting to the ribosomes the sequence of nucleotides that makes possible the translation and the synthesis of proteins.

Once the ribosome translates the information of each codon of the mRNA, a transfer RNA (tRNA) molecule, with a complementary anticodon, provides the amino acid corresponding to the translated codon.

If the mRNA were double-stranded, the translation process would be altered, since binding of the tRNA with the amino acid it carries and mRNA codon would not be possible, as well as the protein synthesis.

Answer:

4. Genes are carried from parents to offspring on chromosomes I think

Answer:

The genetic code is the sequence of nucleotide bases in nucleic acids (DNA and RNA) that code for amino acid chains in proteins. DNA consists of the four nucleotide bases: adenine (A), guanine (G), cytosine (C) and thymine (T). RNA contains the nucleotides adenine, guanine, cytosine and uracil (U).

A gene is a section of a DNA molecule that contains the information to code for one specific protein.

DNA is the genetic material, which is involved in carrying the hereditary information, replication process, mutations, and also in the equal distribution of DNA during the cell division.

Answer:

Viruses are classified into 4 groups based on their shape: filamentous, isometric , enveloped, and head and tail.

Many viruses attach to  host cells to facilitate penetration of the cell membrane, allowing their replication inside the cell.

The virus core contains the small single- or double-stranded genome that encodes the proteins that the virus cannot get from a host cell.

Explanation:

According to the Baltimore classification system, Viruses are classified into seven classes on the basis of their morphology and function.

A Virus may be defined as a type of microorganism that consists of a nucleic acid molecule in a protein coat and infects cells and may cause disease.

Viruses are classified into seven classes, each of which has its own families of viruses and has differing replication strategies.

Class 1: Double-stranded DNA viruses.

This type of virus usually must enter the host nucleus before it is able to replicate. An Example is Adenoviridae.

Class 2: Single-stranded DNA viruses.

Such types of viruses replicate within the nucleus and pertain highly in vertebrates. An example is Circoviridae.

Class 3: Double-stranded RNA viruses.

Such types of viruses do not depend on host polymerases for replication. An example is Birnaviridae.

Class 4: Single-stranded RNA viruses (positive sense).

Such types of viruses have polycistronic mRNA which is translated into a polyprotein. An example is Flaviviridae.

Class 5: Single-stranded RNA viruses (negative sense).

Such types of viruses must be transcribed by viral polymerases into complementary forms. An example is Filoviridae.

Class 6: Single-stranded RNA viruses (positive sense) that replicate through DNA intermediate.

Such types of viruses use the enzyme reverse transcriptase to convert the positive sense RNA into DNA. An example is Retroviruses.

Class 7: Double-stranded DNA viruses that replicate through a single-stranded RNA intermediate.

Such types of viruses have a double-stranded gapped genome that is subsequently filled into a covalently closed circle that serves as the template for the production of viral mRNA. An example is the Hepatitis B virus.

Therefore, it is well described above.

answer:

So daughters get 2 X chromosomes from the mom and dad and if the dad has hemophilia the daughter would get it too and sons would not get because they get Y chromosome from their dad and hemophilia is found in the X chromosome because the X chromosome is the one that has the instructions for making the clotting factor proteins.

Explanation:

A father who has hemophilia has the gene and passes it on to his daughter because daughters get two X chromosomes, one from their mother and the other from their father. This is why daughters of men with hemophilia are called obligate carriers. Since sons only receive a Y chromosome from their father, they would not have inherited hemophilia.

When an organism or insect develops a mechanism for the removal of the pesticide compound is known as pesticide resistance.

The organism or insects develop mechanisms such as the alternation of the binding site of the compound present in the pesticide leading to the development of resistance against the used pesticides. The development of resistance against the pesticide is a slow process, it takes time. The usage of pesticides becomes a failure if organisms develop resistance.

The frequent use of pesticide and insecticides cause changes in the genetic material of the organisms. They help in the development of enzymes and changes in the binding sites. These changes are passed on to the next generation of the organism, which makes the entire population resistant to the particular pesticide and insecticide.

The use of the chemicals should be monitored. Only use when required with rotation.

Answer:

Sweating helps the human body maintain homeostasis by cooling the body when it starts to overheat so the internal temperature is kept more or less the same. When sweat evaporates from the skin, it uses up some of the excess heat energy on the skin, thus helping to keep the body cool.

According to cell theory, all living things are made of cells, and living cells come only from other living cells. Gene theory states that the characteristics of living things are controlled by genes, which are passed from parents to their offspring.

Sample answer: The concentration of oxygen in the atmosphere is maintained at 21 percent by a balance between two opposing processes: removal of oxygen from the atmosphere by most living things and addition of oxygen to the atmosphere by living things such as plants.

Sample answer: The human ability to sweat is an adaptation that helps maintain homeostasis in a hot environment by removing heat from the body when it evaporates. Like other adaptations, the ability to maintain homeostasis by sweating evolved by natural selection sometime in our evolutionary past.

a. Gene theory

b. Homeostasis

B

An adaptation is a trait that helps a living thing survive and reproduce in a given environment. Sample example. The chameleon’s ability to change color to match their background is an adaptation.

False

False

Humans began life as a single cell because we develop from a fertilized egg cell.

Gene theory states that genes are passed down from parents to their offspring. Genes determine the characteristics or traits of an organism. If these traits are particularly beneficial or adaptive, natural selection will cause the organisms with beneficial traits to produce more offspring compared to those without the beneficial traits. This results in a change in traits over time, which is called evolution.

No. Evolution is defined as a change in the characteristics of living things over time. Evolution through natural selection causes differences in the amount of offspring produced. Having offspring (or not) is, by definition, more than one generation.

Sample answer. I think that when ancestors of chameleons could change their color to match their background, they were less likely to be detected and killed by predators than those that couldn’t change their color. Therefore, the individuals that had the color matching ability were more likely to survive and reproduce than those that didn’t. This is an example of natural selection. Over time, this led to the population evolving the color changing ability, as those that didn’t have the ability died out.

Answer:  

Determining bar temperature on Fahrenheit scale -

The temperature of the bar is given as 50 degrees Celsius.

If we know the temperature on the Celsius scale, we can convert it to the Fahrenheit scale.

We know

C / 5 = (F-32) / 9; Where C is the temperature on the Celsius scale and F is the temperature on the Fahrenheit scale.

Now,

50/5 = (F-32) / 9

Or, (F-32) / 9 = 10

Or, F-32 = 90

Or, F = 90 + 32

Or, F = 112 degrees Fahrenheit.

That is, the temperature of the bar on the Fahrenheit scale is 112 degrees Fahrenheit
