When working on a biology assignment, Josh was using information from his textbook to answer questions on the immune system. Because it was his first time learning about the immune system, josh had not yet learned or memorized any of the information. Josh has not consolidated this new information about the immune system into his long-term memory.
In the field of science, long-term memory is the ability of the mind to store a piece of information for longer durations, probably for months, years, or a lifetime. An extended memory of the brain is the long-term memory. On the other hand, short-term memory tends to remain in the brain for a few seconds or minutes.
By learning something, we tend to store information in our long-term memory. As Josh was looking at the immune system for the first time, his mind had not formed a long-term memory for it in order to remember it.

Describe the effects the 3 limiting factors had on the cricket frog population.
Answer: decrease
Increase
Increase
Explanation:
1. When the predators population is increased, there will be high risk to the cricket frog from these predators as they may start attacking them rigorously and ultimately lead to a sharp decline in their population.
2. Pollution is a favorable factor that causes cricket frogs to flourish and increase in number. Thus the higher the pollution level, the higher will be the population of cricket frog
3. Food sources will reduce the competition with in the cricket frog species and hence there population will increase.
During the prophase stage, loosely arranged stands of chromosomes become coiled, shortened and distinct.
True or False?
According to the research, the correct option is false. During the prophase stage, loosely arranged stands of chromosomes don't become coiled, shortened and distinct.
To find the correct option amongst all other options, we need to know more about prophase stage and which characteristics it has.
What is the prophase stage?The first phase of cell division, in which the chromosomes become visible as isolated entities is called the prophase stage. Prophase stage is related to the disintegration of the nuclear membrane and the fixation of the chromosomes in the spindle. In this stage, the chromosomes thicken, the envelope of the nucleus breaks down, and the nucleoli are shared in the cytoplasm, becoming ribosomes.Therefore, we can conclude that according to the research, the correct option is false. During the prophase stage, loosely arranged stands of chromosomes don't become coiled, shortened and distinct.

The circulatory system carries the waste from throughout the organism to them
The circulatory system carries the waste from throughout the body to the excretory system.
In the circulatory system, the renal arteries specifically function to collect the deoxygenated blood and other waste materials from all the different parts of the body and carry it to the kidneys for filtration.
How are the circulatory system and excretory system related?
Due to the fact that the excretory system filters the circulatory system's blood, the excretory system and the circulatory system work in tandem. the primary organ of the kidneys' excretory system. Kidneys filter blood from the circulatory system as it travels through them.
Through the renal artery, blood enters your kidney. Up until the blood reaches the nephrons, this huge blood channel divides into smaller and smaller blood vessels. Your blood is filtered by the glomeruli, which are microscopic blood vessels, in the nephron before leaving your kidney through the renal vein.

Eukaryotic cells store their dna in the form of linear chromosomes. This creates problems for replication of dna at the ends of the chromosomes because.
Eukaryotic cells store their DNA in the form of linear chromosomes. This creates problems for the replication of DNA at the ends of the chromosomes because of the fact that DNA polymerase can only synthesize DNA in a 5' to 3' orientation.
The family of enzymes that catalyze the synthesis of DNA molecules from nucleoside triphosphates, the basic building blocks of DNA, includes DNA polymerase. These enzymes, which are required for DNA replication, typically function in groups to divide an initial DNA duplex into two identical copies.
DNA polymerases' major function is to efficiently and properly replicate the genome in order to maintain the genetic code and ensure that it is faithfully passed down through the generations. While other DNA polymerases are primarily involved in DNA repair and translesion DNA synthesis, the third polymerase, Pol III, is responsible for duplicating the chromosomal DNA.
There are five DNA polymerases found in eukaryotic cells: and. The polymerase enzyme, which is found in mitochondria, is in charge of replicating mitochondrial DNA. The remaining four enzymes are thought to be involved in nuclear DNA replication because they are found in the nucleus.
