Answer:
a. True
Explanation:
Bruce Wallace was a professor emeritus of genetics who performed many population studies. He worked in 1958 at the University of Cornell as a professor of genetics. In 1963, he performed a population study wherein the recessive allele It was at a frequency of 0.5. The population was propagated for 10 generations and the frequency of It for each generation was determined.
The result of this study showed that lt/lt died without reproducing, whereas, individuals with genotype +/+ were normal.
1.An increase in the population of an organism would most likely be associated with which of the following?
A.an increase in animals that prey on an organism.
B.A decrease in necessary resources.
C.An expansion of suitable living space.
D.A series of severe weather events in the habitat.
Answer:
a series of severe weather events in the habitat
An increase in the population of an organism would most likely be associated with a series of severe weather events in the habitat. The correct option is D.
What is the population?A collection of creatures from the same species that can interact to create fertile progeny. It is on a level above organisms but below the ecosystem and community.
An ecosystem is a level of organization where several communities of various species and the associated abiotic elements interact. It is the place where different population interacts with each other.
A biosphere and a biome are larger organizational levels than this one. Communities are levels of the organization where various populations coexist and engage in social interactions.
Therefore, the correct option is D. A series of severe weather events in the habitat.

How does cell division relate to the process of asexual reproduction ?
Answer:
sexual reproduction occurs by cell division during mitosis to produce two or more genetically identical offspring. Sexual reproduction occurs by the release of haploid gametes (e.g., sperm and egg cells) that fuse to produce a zygote with genetic characteristics contributed by both of the parent organisms.

How are enzymes important for biochemical reactions?Enzymes are often called a catalyst because they increase can the speed of a biochemical reaction. Scientists often measure how quickly biochemical reactions occur in cells. The time it takes for a biochemical reaction to start and finish is known as the reaction rate.
Enzymes share two key characteristics with all other catalysts. First, they speed up chemical processes without being eaten or irreversibly changed by the process. They also speed up reactions while maintaining the chemical equilibrium between reactants and products.
Therefore, the enzyme acts as a catalyst to speed up a biochemical reaction.

Binding of the lac repressor protein to the lac operator is regulated allosterically. This means that the presence of a specific small molecule that binds to the lac repressor controls whether the repressor can bind to the lac operator, and therefore whether the operon is turned on or off. Can you sort the following conditions based on whether they are associated with the lac operon being turned ON or turned OFF?
a. Allolactose is absent
b. Allolactose is present
c. RNA polymerase cannot transcribe the operan genes
d. The lac repressor protein cannot bind to the lac operator
Answer:
a. OFF
b. ON
c. OFF
d. ON
Explanation:
Allosteric regulation is a process by which a particular molecule activates or inhibits an enzyme, by binding to a site different from the active site of the enzyme. Allolactose is a disaccharide that binds to the allosteric site of the lac repressor protein, triggering a conformational change in the protein that prevents the binding of this repressor to DNA. Moreover, RNA polymerase (RNA pol) is an enzyme required for the process of transcription, and therefore when this enzyme cannot bind to operon genes the lac operon is being turned OFF. Finally, the lac operator is a nucleotide sequence where RNA pol binds, and the lac repressor binds to the lac operator in order to block the transcription of the lac operon.

8. Genes are sorted and recombined to produce gametes. Which statement describes a possible result of this process?
A. Gametes always form with genetic material identical to the parent
B.Gametes are formed with the same number of chromosomes as the parent cells
C.Offspring display half of their traits from their mother and half of their traits from their father
D.Offspring have traits not displayed by either parent
Answer:
c option is correct.
Explanation:
gametes are produced by meiosis during which genes get crossed in a process of crossing over ad new recombinent characters are produces. these gametes fertilized and offsprigs have multiple characters they get from their mother and faaher. so offsprimgs have characters half from mother and other half from father.
Genes often produce gametes. The statement that describes a possible result of this process is that Offspring display half of their traits from their mother and half of their traits from their father.
What is genes and gametes?A gene is known to be the molecular unit of heredity of all living beings.
A gamete is known to be a cell that comes together with another cell during fertilization that takes place in organisms that reproduce and this is a product of the male and the female gamete.

What is poisonous enough to kill 100,000 turkeys? That’s the question asked by scientists who studied a mass die-off of turkeys in Great Britain. It turned out that all the turkeys had eaten peanuts from Brazil. A fungus was growing on the peanuts. The fungus produced a dangerous poison called aflatoxin. Aflatoxins cause stomach pain, lung failure, cancer, and death in people and animals.
Farmers make a great effort to prevent fungi from growing on their stored crops. In a pile of grain or nuts, fungi have plenty of food and living space. The best way for farmers to prevent fungi from growing is to make sure there is not enough for fungi to survive and grow.

In cystic fibrosis, an important protein destined for the plasma membrane never makes it beyond the Golgi complex. This protein is necessary for Na and Cl- transport and is critical for maintaining mucous secretions of the appropriate consistency. Devise an explanation for why this may occur.
Answer:
The correct answer is - Golgi apparatus marks or tags on this protein as incorrect or dysfunctional tags which then prevents it from transported to the membrane.
Explanation:
The role of the Golgi apparatus is to process and package the proteins produced and come from ER and transfer them to the plasma membrane in order to transfer them to their target sites.
The Golgi apparatus marks or tags the proteins that are incorrect or dysfunctional, in order to prevent these proteins from transporting to the plasma membrane and harm the membrane. In CF, the case is similar as the Golgi apparatus tags these proteins as incorrect or dysfunctional.
