please help me. I been stuck on this question for a long time :(
Answer:
Explanation:
1. Climate change is caused by changes in the earth's atmosphere in the amounts of greenhouse gases released into the air. Some scientists believe that 100% of global warming is due to humans. The largest contribution comes from burning fossil fuels because it releases carbon dioxide gas to the air, which is done by humans. Other factors that contribute to climate change include:
>Deforestation- clearing out trees affects wildlife, ecosystems, whether patterns. Forests cover 30% of the lands mass and clearing them leaves many animals without homes.
>Waste from factories- they release tonnes of toxic fumes into the air.
> Agriculture and farming- this is a surprising contributing factor to global warming. Animals produce a greenhouse gas called methane and when livestock are grazed at a large scale, the amount of methane produced is a big contributor to global warming.
Some fertilizers release nitrous oxide, which is another greenhouse gas.
2. The effects of global warming include:
>Melting glaciers- this leaves many animals without homes and it also causes a rise in sea levels which causes flooding. (that's 3 effects)
>Worsening droughts- this leaves many humans to die as they have no food or water.
>Increasing tornadoes

Rima eat guava explain how the teeth tongue and sliva will help to break it down
Answer:
Please find the role of teeth, tongue and saliva in digesting guava below
Explanation:
Digestion is generally the process of breaking down complex food substances into their simplest form. However, as easy as this sounds, there are series of processes that must take place in between to achieve the final result.
Once a food substance like guava enters the mouth (ingestion), it initially gets chewed by the TEETH in order to break it down to smaller masses that can be swallowed. During the process of chewing, the TONGUE helps to move the food around the mouth and later helps push it down the gullet/digestive tract. SALIVA, on the other hand, creates a moisturizing environment for the food to form a Bolus (round mass of food ready to pass down the esophagus). The saliva also contains an enzyme called AMYLASE that helps chemically degrade starch content of the food before passed through the digestive tract.

When fats are used as an energy source, the glycerol portion enters ________ when it has been converted to ________. When fats are used as an energy source, the glycerol portion enters ________ when it has been converted to ________. glycolysis; dihydroxyacetone phosphate the electron transport system; coenzyme Q glycolysis; fructose-6-phosphate the citric acid cycle; pyruvate the citric acid cycle; acetyl CoA
Answer:
glycolysis; dihydroxyacetone phosphate
When fats are used as an energy source, the glycerol portion enters the glycolysis when it has been converted to dihydroxyacetone phosphate. Thus, the correct option is A.
What is the Glycolysis?Glycolysis may be defined as the process in which glucose (sugar) is partially broken down by cells in enzyme reactions that do not need oxygen.
In order to obtain energy from fats, triglycerides must be broken down into fatty acids and glycerol through hydrolysis. The fatty acids enter to Krebs cycle and are converted into acetyl CoA.
While the glycerol portion enters into glycolysis and is converted into dihydroxyacetone phosphate.
Therefore, the correct option for this question is A.

A student finds that the mass of 25mL of an unknown liquid is 20.5g. What is the density of this substance?
Answer:
Density, [tex]d=0.82\ g/cm^3[/tex]
Explanation:
It is given that,
Mass of unknown liquid is 20.5 kg
Volume, V = 25 mL
We know that, 1 mL = 1 cm³
25 mL = 25 cm³
The density of the substance is equal to its mass per unit volume. So,
[tex]d=\dfrac{m}{V}\\\\d=\dfrac{20.5\ g}{25\ cm^3}\\\\d=0.82\ g/cm^3[/tex]
So, the density of this substance is [tex]0.82\ g/cm^3[/tex].

Ultra-high-temperature sterilization effectively reduces microbes that cause spoilage. removes only mesophilic microbes. reduces microbes that cause disease. removes all microbes that cause diseases or spoilage. reduces microbes that cause disease or spoilage.
Answer:
kills all microbes that cause disease or spoilage.
Explanation:
There are different methods of sterilization, such as ultraviolet radiation, autoclave mechanisms, etc.
The sterilization mechanisms eliminate the microorganisms completely, thus generating sterile surfaces.
These mechanisms are used with surgical instruments, the operating room environment.
The autoclave method is the most widely used today due to its economical price, its ease of use and its practicality.
Sterilization methods must be strictly controlled with pilot or test microbiological cultures to be able to corroborate that these mechanisms function correctly, since otherwise they could trigger strong pathologies due to cross contamination.
During the process of translation in a eukaryote messenger RNA is spliced in the nucleus. amino acids are synthesized by RNA polymerase. transfer RNAs are joined together by a large enzyme complex. ribosomes must be imported into the nucleus. mRNA interacts with ribosomes in the cytoplasm.
Answer:
mRNA interacts with ribosomes in the cytoplasm.
Explanation:
The correct option would be that mRNA interacts with ribosomes in the cytoplasm.
Translation involves the use of genetic codes in mRNA to synthesize amino acids that are eventually linked together by polypeptide bonds to form proteins.
During translation, the mRNA synthesized in the nucleus is transported into the cytoplasm where it gets attached to the ribosome and another RNA - the tRNA. The codons on the mRNA eventually match with the anticodon of the tRNA with the later releasing the amino acid that corresponds to each codon.
Hence, the correct answer out of all the options is that mRNA interacts with ribosomes in the cytoplasm.
