What causes psoriasis primarily?Psoriasis doesn't have a clear etiology. Infection-fighting cells accidentally kill healthy skin cells, which is thought to be an immune system issue. Both genetics and environmental variables are thought to be involved, according to researchers. It is not spreadable to other people.Silvery scales and large red patches of skin are symptoms of psoriasis. Patches can affect other areas besides the elbows, knees, scalp, lower back, cheeks, palms, and soles of feet (fingernails, toenails, and mouth).

For mammals living in cold habitats, would smaller or larger species require relatively thicker fur?.
Answer: Smaller species would have a greater need for thicker fur
Explanation: Bigger animals have a bigger surface area to volume ratio meaning they will not lose heat to the outside as much as a smaller animal who would have a smaller ratio. I think that would mean that the smaller animal would be in greater need of a thicker coat to help them stay warm.

describe the basic functions of animal body system
The basic functions of the animal body system are regulation of the internal environment (homeostasis), nutrient absorption, reproduction, and defense against injury or illness.
Homeostasis:
A biological system's tendency to preserve stability while responding to conditions that are best for survival is known as homeostasis. If homeostasis is achieved, life continues; if it is not, tragedy or death results.
Nutrient absorption:
The upper small intestine's hollow serves as a reservoir for absorbed food molecules, water, and dietary minerals. The majority of the absorbed substances penetrate the mucosa into the blood and are transported there by the bloodstream to other body areas for storage or additional chemical alterations.
Reproduction:
The process of producing off-springs that are biologically or genetically similar to the parent organisms is known as reproduction. Reproduction allows and ensures the continuity of species, it's the main feature of life on earth.
Defense against injury or illness:
So it is the smart body system that helps defend against illness is called immune power. The immune system is created of a network of cells, tissues, and organs that employ along to shield the body.

Regulation of the internal environment (homeostasis), food intake, reproduction, and protection against harm or illness are the fundamental bodily processes of animals.
What does the animal body system do?Homeostasis refers to a biological system's propensity to maintain stability while reacting to circumstances that are most conducive to survival. Life continues if an equilibrium is attained; if not, catastrophe or death occurs.
Food molecules, water, and dietary minerals are stored in the hollow of the upper small intestine. Most compounds that are absorbed pass through the mucosa into the blood and are then carried by the bloodstream to other body parts for storage or further chemical changes.
Reproduction is the process of creating offspring that are biologically or genetically similar to the parent organisms. The primary characteristic of life on earth is reproduction, which enables and secures the continuation of species.

What is recombinant DNA ?A common bacterium's genetic code could be altered to include a human gene thanks to a technique called recombinant DNA. This "recombinant" microbe might now make the protein that the human gene codes for. In a lab, researchers create the human insulin gene. By using fermentation in microorganisms and recombinant DNA technologies, "recombinant human insulin" became widely accessible (bacteria or yeast). In comparison to semisynthetic insulin, recombinant insulin has a higher level of purity and a more reliable quality. One of the first products of biotechnology was recombinant human insulin. It was created in response to the requirement for an ongoing and adequate global supply. The semisynthetic insulins created by modifying animal insulins and the animal insulins themselves were superseded by recombinant human insulin, after being correctly detected,

EXPLAIN IN DETAIL HOW THE TWO RELATES TO THE CELL THEORY
The following lists components of the nature of science. Explain how at least two of these are related to the cell theory:
Scientific knowledge is durable yet subject to change
Science is a social activity
Knowledge is created through the process of science. Both thorough observation of occurrences and the creation of theories to explain those observations are essential to the process. Knowledge will always change since new observations could refute accepted ideas. No matter how well one theory explains a given collection of observations, it is always feasible that another theory will fit the same set of observations just as well, better, or across a larger range.
The majority of scientific knowledge is enduring, despite the fact that scientists reject the idea of discovering perfect truth and accept some doubt as a component of nature. Science typically modifies ideas rather than rejects them completely because strong theories are more likely to endure, advance in accuracy, and gain widespread acceptance. For instance, when developing the theory of relativity, Albert Einstein did not completely reject the Newtonian laws of motion but rather demonstrated that they were only a rough approximation with a more general concept.
This seems like a strange restriction because it is obvious that both modern science and the majority of earlier science is a social activity. For information, samples, techniques, and many other things, scientists depend on one another. Their interactions are occasionally competitive and frequently cooperative.

Possible explanation for these results is that the proofreading mechanism of DNA polymerase was not working properly.
How is the proofreading process explained?Proofreading mechanisms are crucial for reducing the rate of mutation in a newly generated DNA molecule during DNA replication.
DNA polymerase 3 reads the daughter DNA strands in a 3" to 5" orientation by exonuclease activity, which is how the proofreading activity is carried out.
Incorrect bases are excised and replaced with the right bases by DNA polymerase 3's proofreading activity if they are discovered in the daughter DNA molecule.

The most common isotope of uranium has an atomic number of 92 and mass number of 238. If a uranium atom alpha decays and emits a helium nucleus, what will the atomic number of the daughter nucleus be?.
If a uranium atom alpha decays and emits a helium nucleus, the atomic number of the daughter nucleus is 90.
Alpha particle is a helium nucleus thus decay of alpha particle is decay of 42He
42He = α with emission of helium nucleus emit energy (Q)
Thus mass number decreased by 4 and atomic number decreased by 2 of daughter nucleus.
Alpha decay represented by
AZX → A-4Z-2Y + 42He + Q
So alpha decay of U-238 represented by
23892U → 23490Th + 42He + Q
After alpha decay of U-238 formed daughter nucleus Th – 234 and He -4
Atomic number of daughter nucleus = 90

If two species are able to interbreed but produce sterile hybrids, their speices integrity is maintained by _____.
A postzygotic barrier protects the species integrity of two species that can interbreed but produce sterile hybrids.
What is postzygotic barrier ?A mechanism that prevents reproduction after fertilization and zygote formation is known as a postzygotic barrier. In the case of hybrid inviability, a mating between two individuals produces a hybrid that does not survive past the embryonic stages.
While we waited for our regular hamsters to arrive, we learned a lot about the different types of barriers that can cause reproductive isolation prior to fertilization. Matings between our flying and non-flying hamsters result in fertilization and the formation of zygote. As a result, it appears that the gene pools of the two types of hamsters are not isolated prezygotically. Even if the two types of hamsters were able to mate and produce a zygote, that zygote would still have to mature to a reproductive age and produce progeny for the two hamsters to be simply variants of the same species.
Although prezygotic barriers did not cause speciation, a mechanism that occurs after zygote formation could still be isolating the gene pools of the two hamster populations. Postzygotic reproductive barriers form after the zygote has formed, reducing either the viability (the ability to avoid dying) or the reproductive capacity of the hybrid offspring. Postzygotic mechanisms such as hybrid zygote abnormality, hybrid infertility, and low hybrid viability may still distinguish flying hamsters from non-flying hamsters.
