The Lac Operon is a set of genes that controls the production of lactase the enzyme that digests
lactose. In the top picture: The gene is "turned off" resulting in no mRNA being made. In the
bottom picture: The gene is "turned on" allowing the RNA polymerase express the genes,
resulting in production of the lactase enzyme.
which statement is not correct about the lac operon?
Answer:
The lactose present prevents the production of lactase
Explanation:
This question is describing a set of genes in bacteria called LAC OPERON. Lac operon controls the production of lactase, which is the enzyme that digests lactose. However, this gene can be regulated at the transcription level i.e caused to be transcribed or not depending on certain factors.
According to the question, lac operon, which regulates the production of enzymes will be transcribed and subsequently translated i.e. turned on when there is a substrate (lactose) that the produced enzyme will work on. However, when there is no need of the lactase enzyme or there is absence of lactose (substrate), the lac operon gene is turned off.
Note that, the statement that "The presence of lactose prevents the production of lactase" is not correct.
17. At the end of their biology unit, 7th grade students were asked to make a glossary of biological terms. Which student did the best job of defining the word "heredity"?
Answer:
The question is incomplete, I found a matching question online:
At the end of their biology unit, 7th grade students were asked to make a glossary of biological terms. Which student did the best job of defining the word "heredity"?
A) Kendall- Heredity is the study of chromosomes and the genes that they contain.
B) Carla- Heredity is the passing of genetic information contained in chromosomes from one generation to the next.
C) Joseph- Heredity is the study of human characteristics passed down from parent to offspring.
D) Devon- Heredity is the reason that tall parents will usually have tall children.
Answer:
The correct answer is:
Carla- Heredity is the passing of genetic information contained in chromosomes from one generation to the next. (B)
Explanation:
Heredity, also known as inheritance is the passing down of genetic traits and genetic information from parents to their offspring through reproduction (sexual or asexual), and this information is contained in DNA materials called chromosomes.
Carla's definition most appropriatly captures the context of genetics, while Kendall and Joseph rather defined "genetics", which is the study of heredity.
Devon did not give a definition, but rather an example.

An event that restricts the size of a population such as weather events like drought or flood is likely a
1)density dependent limiting factor
2)density independent limiting factor
3)immigration
4)emmigration
Answer:
The correct answer is - 2) density-independent limiting factor.
Explanation:
Density-independent limiting factors are the factors that cause a change in the size of the population without getting influenced by the density of the population.
Density-independent limiting factors include biotic or abiotic factors with catastrophic conditions such as natural disasters such as floods, earthquakes, drought, fires, and many more.
Drought affects the size of the population by increasing competition in the ecosystem for resources.

why is important to use an organism with a recessive phenotype in a cross with an organism of unknown Genotype
Answer:
One of the central conclusions Mendel reached after studying and breeding multiple generations of pea plants was the idea that "[you cannot] draw from the external resemblances [any] conclusions as to [the plants'] internal nature." Today, scientists use the word "phenotype" to refer to what Mendel termed an organism's "external resemblance," and the word "genotype" to refer to what Mendel termed an organism's "internal nature." Thus, to restate Mendel's conclusion in modern terms, an organism's genotype cannot be inferred by simply observing its phenotype. Indeed, Mendel's experiments revealed that phenotypes could be hidden in one generation, only to reemerge in subsequent generations. Mendel thus wondered how organisms preserved the "elementen" (or hereditary material) associated with these traits in the intervening generation, when the traits were hidden from view.
It is important to use an organism with a recessive phenotype in a cross with an organism of an unknown genotype to identify the recessive traits.
What are phenotype and genotype?The observable traits of an individual are the result of gene expression; the clinical manifestation of a person with a certain genotype is called the phenotype of an individual. Some examples of the phenotype are height, skin color, eye color, hair nature, etc.
The term "genotype" refers to an organism's whole gene pool, or, in other words, the genetic makeup of that creature. The phrase can also be used to describe the alleles, or different forms of a gene, that an organism carries in a more specific meaning.
A recessive phenotype is used in a cross with an organism of unknown Genotype to identify the recessive traits.

Can you write an essay about what makes a good rapper.
I will mark you Brainly.
Answer:
There are many rappers out there in the world yet only a few of them are really well known and recognized. Of course this is because they meet peoples expectations. Different people have different opinions on what makes a good rapper. Things that I think make a good rapper is that they need to have good flow, meaningful lyrics that actually make sense and not just rhyme any word with another that doesn't make sense. Another thing is how they are like as a person as well. If they are a pretty decent human being and meets peoples expectations then they will be considered as a good rapper. If the person is not only ignorant but also can't rap well then they are considered bad. Like I said many people have different opinions but these are just mines.

How are organisms classified in the phylum category?
based on basic body structure
color
cell structure
chromosomes
Answer:
Basic body structure.
Explanation:
Organisms classified in the phylum category on the basis of their basic body structure. Organisms are classified in the groups and subgroups on the basis of similarities and differences. Those organisms that show resemblance is to be put in the same group. They have some similar characteristics such mode of reproduction, mobility, feeding behaviour and body structure etc.

Answer:
The energy that goes into the trumpet to create the sound is a standing wave. (I think...)
Explanation:
When a person is blowing into a trumpet, a standing wave is being created based on the shape of the instrument. The trumpet is formed to produce sound. Notes sound different from one another because they represent different frequencies and therefore a different numbers of nodes.
What is the variety of gene combinations that exist within a population called?
A population's genetic diversity can be quantified via genetic variation, genetic diversity is the term used to describe the genetic variation of an entire species.
What is genetic variation?Each variant of a gene is referred to as an allele, and genetic variations are the variances in DNA segments or genes across individuals.
A population's naturally occurring genetic diversity is studied by population geneticists. A population's gene pool is made up of all the genes and different alternative or allelic versions of those genes.
Some genes exist in a number of forms, all of which share the same genetic locus on a chromosome.
Therefore, genetic diversity is the variety of gene combinations that exist within a population.

Energy that is released from the cellular respiration is called as the ATP that is adenosine triphosphate. It is the energy currency of the cell.
What is the number of phosphate in ATP ?The number of phosphates in the molecule of ATP is 3 phosphates.
Glucose and the other food's molecules get broken down by the controlled stepwise oxidation in order to just provide the chemical energy in form of ATP and the NADH. Energy that is released during breakdown of the glucose and the other organic fuel molecules that are from the carbohydrates with fats and the proteins in the glycolysis is just captured and then stored in the ATP.
During the cellular respiration the glucose is just broken down in presence of the oxygen in order to just produce the carbon dioxide with water. Energy that is just released during reaction is just captured by energy-carrying molecule that is ATP (adenosine triphosphate).
