Descrlbe the relationshlp among the agents of disease, the Infectious dose, and the health of
a host.
Answer:
The number of pathogens that are required to infect a host, termed infective dose, varies dramatically across pathogen species. It has recently been predicted that infective dose will depend upon the mode of action of the molecules that pathogens use to facilitate their infection. Specifically, pathogens which use locally acting molecules will require a lower infective dose than pathogens that use distantly acting molecules. Furthermore, it has also been predicted that pathogens with distantly acting immune modulators may be more virulent because they have a large number of cells in the inoculums, which will cause more harm to host cells. We formally test these predictions for the first time using data on 43 different human pathogens from a range of taxonomic groups with diverse life-histories. We found that pathogens using local action do have lower infective doses, but are not less virulent than those using distant action. Instead, we found that virulence was negatively correlated with infective dose, and higher in pathogens infecting wounded skin, compared with those ingested or inhaled. More generally, our results show that broad-scale comparative analyses can explain variation in parasite traits such as infective dose and virulence, whilst highlighting the importance of mechanistic details.

While carrying out a hanging drop experiment, one of the researchers forgot to add grease to the multi well plate. How will this affect the crystalization process?
Answer and Explanation: The role of oil/grease in the hanging drop experiment can not be over emphasised especially for small volume trials.
The macromolecule solution to be crystalized is mixed with a precipitating agent on a glass plate. This is then inverted over greased wells creating an overhang.
Greasing the wells ensures a proper seal as it acts as an inert sealant that prevents the evaporation of the solution, but also can easily contaminate the macromolecule solution to be crystalized. Grease also affects the crystallization process throughout its stages of nucleation and growth, and also enhances the stability of the emerging crystals.

It would be a flat line that crosses the high temperature graph.
It would be the opposite of the high temperature graph.
It would be a flat line below the high temperature graph.
Answer:
It would be the opposite of the high temperature graph.
Explanation:
i got it right and thats all that matters
The graph for average low temperatures would look like the opposite of the high-temperature graph.
What is a temperature graph?A climate graph displays yearly temperature and precipitation statistics for a particular location. Temperature is measured using the numbers on the left-hand side of the chart. The average temperature for each month is plotted on the graph with a red dot and the dots are then connected in a smooth, red line.
What graphs are used in weather?Two common types of graphs are bar graphs and line graphs. Bar graphs use vertical or horizontal rectangles (bars) to represent a specified quantity. Line graphs use points to identify values, and then connect each point with a line that shows the fluctuations in the data.

Make a claim explaining why it is important for gametes to be haploid. What
would happen if gametes were diploid? Use evidence to support your claim
Somatic cells are diploid(they have 2n chromosomes) while gametes are haploid(they have n chromosomes). During fertilization two gametes fuse to form a diploid cell(n+n=2n). If gametes were diploid(2n chromosomes) every generation the number of chromosomes would double (2n+2n=4n)
Somatic cells are diploid(they have 2n chromosomes) while gametes are haploid(they have n chromosomes).
What are Somatic cells?During fertilization two gametes fuse to form a diploid cell(n+n=2n). If gametes were diploid(2n chromosomes) every generation the number of chromosomes would double (2n+2n=4n).
The body's somatic cells are those that are neither sperm or egg cells (which are called germ cells).
Somatic cells in humans are diploid, which means they have two sets of chromosomes, one from each parent. Somatic cell DNA mutations can have an impact on an individual, but they cannot be passed on to the individual's progeny.
Therefore, Somatic cells are diploid(they have 2n chromosomes) while gametes are haploid(they have n chromosomes).

What is the diploid of the zygote produced by fertilization—haploid or diploid?
Answer:
"Haploid" refers to any cell that has 23 chromosomes (half of the total 46). "Gametes" are specifically sex cells that have 23 chromosomes. "Diploid" refers to any cell that has all 46 chromosomes. "Zygote" is the result of two gamete (haploid) cells fusing, and becoming a diploid cell.

If the grass is removed, then the grasshopper will not get any food. If the grasshopper does not get food, then the species will decrease and eventually die out. When the grasshopper dies out, then the lizard and the frog will have no food and they will die out. When they die, the snake will have only mice to eat, and there would be more competition. In the end, the food web would be unbalanced.

what part of the muscle cell most closely regulates protein synthesis?
1) Endoplasmic Retriculum
2)Lysosome
3)Nucleus
4)DNA
Answer:
ENDOPLASMIC RETRICULUMExplanation:
Thank uhh!!!!!!!!❤
Muscle cell most closely regulates protein synthesis it follows that ribosomes, which are found in the cytoplasm and rough endoplasmic reticulum, are where protein synthesis or translation of m-RNA to protein occurs, hence option 1 is correct.
What is the endoplasmic reticulum?Sarcoplasmic reticulum is a specific type of ER found in skeletal muscle (SR). The SR is essential for both the contraction of muscles and the preservation of muscle homeostasis because it serves as a calcium storage depot and controls the release of calcium during myofibrillar contraction.
Ribosomes: Ribosomes are crucial cell organelles involved in the production of proteins. Proteins and RNA found in ribosomes assist in translating genetic instructions into proteins.
Therefore, the endoplasmic reticulum part of the muscle cell most closely regulates protein synthesis.

What is the Gila Monster’s advantage/disadvantage?
The Gila monster is one of only a handful of venomous lizards in the world. Others include the similar-looking Mexican beaded lizards, as well as iguanas and monitor lizards. Its venom is a fairly mild neurotoxin. And though a Gila bite is extremely painful, none has resulted in a reported human death.
It has been accused of many things, such as spitting venom, leaping several feet in the air to attack, stinging with its tongue, and killing people with gusts of poisonous breath. ... It may even chew so that the venom goes deeper into the wound. A Gila monster bite is painful to humans, but it rarely causes death.
Powerful muscles control the jaws and give the Gila Monster a bite like a bulldog--it just won't let go. This gives the venom a chance to work, weakening or disabling the lizard's prey.

What are constants or controlling variables in an experiment? What would be some constants from the experiment mentioned above?
Essentially, a control variable is what is kept the same throughout the experiment, and it is not of primary concern in the experimental outcome. Any change in a control variable in an experiment would invalidate the correlation of dependent variables (DV) to the independent variable (IV), thus skewing the results.

What do you mean by upwelling movements?Upwelling is the natural process which brings cold, nutrient-rich water to the surface. A huge upwelling regularly occurs off the coast of Peru, which enjoys a large fishing industry as a result.
The upward movement of this deep, colder water is called upwelling. The deeper water that rises to the surface during upwelling is rich in nutrients. These nutrients “fertilize” surface waters, encouraging the growth of plant life, including phytoplankton.
Water that rises to the surface as a result of upwelling is typically colder and is rich in nutrients. These nutrients “fertilize” surface waters, meaning that these surface waters often have high biological productivity.

Explain why transboundary environmental threats like pollution are a problem for both parties, even if one community is principally responsible for the pollution.
Answer:
Due to its spreading nature.
Explanation:
Transboundary environmental threats like pollution is a problem for both parties i. e. one that is producing pollution and the other which is not producing it, because pollution can't remain at one place and spread from one part to another part of the earth due to open environment. So due to its spreading, it affected both the producing and non-producing parties.
Answer:
Even when pollution originates on one side of a border, it often spreads through the environment beyond the point of origin, becoming a shared problem. It is important to track the sources of pollution to identify the policies and sources for prevention efforts, but regardless of the source of pollution, once a border area becomes polluted, the pollution is a health threat for all individuals on either side of the border.
