Tapeworms enter the human stomach through food. They feed on nutrients in the stomach and cause infections in the body. What does this association depict?
Answer:
Tapeworms are a parasite of humans
Explanation:
Tapeworm infection is caused by ingesting food or water contaminated with tapeworm eggs or larvae. If you ingest certain tapeworm eggs, they can migrate outside your intestines and form larval cysts in body tissues and organs (invasive infection).

B. What are two reasons that this layer can contain so much water vapor? (2 points)
The two reasons that this layer ( Troposphere ) will contain much water vapor are :
AltitudeAir compressibility The layer of the atmosphere with the most water vaporThe troposphere contains so much of the water vapor present in the atmosphere due to gravity and the compressibility air. As we move higher above the earth surface, the density of the atmosphere decreases rapidly. causing the majority of water vapor to be retained at the troposphere. which is lowest part of the atmosphere closest to the earth surface.
Hence we can conclude that The two reasons that this layer ( Troposphere ) will contain much water vapor are : Altitude and Air compressibility.

(i) What is fertilisation? Distinguish between external fertilisation and internal fertilisation. (ii) What is the site of fertilisation in human beings?
What Is Internal Fertilization? Syngamy of gametes occurs inside the female body after insemination through copulationObserved in birds, mammals, birds occurring in terrestrial plants and animals, also in some of the aquatic entities. This is observed in three ways – ovoviviparity (eggs retained in the female body, hatched when fully developed, oviparity(egg-laying), viviparity(offsprings develop within the female body) Observes in plants such as bryophytes, pteridophytesWhat Is External Fertilization?Syngamy of gametes outside the female body/outer environment, notably in water bodiesObserved in few vertebrates, sea urchins, fish, aquatic invertebrates, almost all amphibiansDeposition of sperms and eggs by males and females in open surroundings is known as spawningBroadcast fertilization – used when sperms swim through the water uniting with eggs to fertilizeii) In humans, the process of fertilization takes place in the fallopian tube. During this process, semen comprising thousands of sperms are inseminated into the female vagina during coitus. The sperms move towards the uterus and reach the opening of the fallopian tube.✯ Hope this helps ✯

What was Hans Molisch’s hypothesis?
Answer:
Molisch’s test is a chemical test which is used to check for the presence of carbohydrates in a given analyte. This test is named after Czech-Austrian botanist Hans Molisch, who is credited with its discovery. Molisch’s test involves the addition of Molisch’s reagent (a solution of ∝-naphthol in ethanol) to the analyte and the subsequent addition of a few drops of concentrated H2SO4 (sulphuric acid) to the mixture.Which testing method is considered better than traditional chemical analysis testing?
methods of analyzing trace evidence are more accurate, faster, and can be automated. These include mass spectroscopy, infrared spectroscopy, and gas-liquid chromatography.
The Trace Materials Unit uses methods and techniques to predict items of evidence. Instrumental methods are considered faster in providing results as compared to traditional chemical analysis.
What is the Instrumental method?Instrumental analysis is a field of analytical chemistry that helps to investigate analytes using some sort of scientific instrument.
Many of the instrumental methods can be done for both qualitative and quantitative analysis.
The major categories of instrumental methods are as follows:
Spectral. Electroanalytical. Separatory.Instrumental methods are considered much faster at producing results as compared to traditional chemical analysis. This factor is often important during a crime investigation.
Thus, the instrumental method is considered better as compared to chemical analysis.

Look at the table you filled in above. How does the numbers for how much the snakes are consumed compare to how much these predators consume other organisms in the habitat (particularly mammals)? What could be a reason for the differences?
The number of organisms decreases on movement from producers to consumers in a food chain. This happens due to decreased energy levels at higher trophic levels.
What is a food chain?Food chain is the sequence of matter and energy transfers as food from one organism to another.
Food chains interconnect locally into a food web as most organisms consume more than one type of animal or plant.
The number of organisms decreases on movement from producers to consumers in a food chain. This happens due to decreased energy levels at higher trophic levels.
Thus, it can be concluded that this is the main reason behind the number of snakes consumed as compared to other organisms.
