A small child managed to eat a bit of dirt while playing outside. Which of the following would prevent the child from getting sick from the bacteria ingested? A If there were not a pathogenic bacteria in the dirt B If the child had previously taken antibiotics for that type of bacteria C If the child already had the antibodies to fight the bacteria D If the child’s cells had complementary receptor molecules that bind to the bacteria

Answer:

C If the child already had the antibodies to fight the bacteria

Explanation:

There are a lot of bacteria that we have already storage antibodies for, our immune system is like a database of antibodies that learns with every disease we get, some of them won´t even manifest, because our immune system is strong and produces enough antibodies to counterattack the germs. So from the options given, the most reasonable and possible is that the kid already had the antibodies to fight that bacteria.

Bacteria, like the Lactobacillus acidophilus use sugar as an energy source for anaerobic cellular respiration. This process produces much less ATP than aerobic respiration and does not produce carbon dioxide as a by-product. It does, however, give yogurt its sour taste and prevents other food spoiling bacteria from developing. This is a description of A) phosphorylation. B) alcohol fermentation. C) lactic acid fermentation. D) the electron transport system.

Answer is C) lactic acid fermentation.

Lactic acid fermentation is a metabolic process by which sugar is converted into cellular energy and lactate or lactic acid in solution. No carbon dioxide is evolve in the process. This conversion is done by lactobacillus bacteria in absence of oxygen. The bacteria that make yogurt carry out lactic acid fermentation.

Question 5 options: True False

Answer:

1. water and carbon cycle

2. carbon cycle

3. nitrogen compounds in the air

4. eutrophication

5. True

Explanation:

Deforestation is the outright removal of forest layers and conversion of such land to other uses. Forest layers serve as sinks for carbon and also as filters for water running off to streams and seas. Hence, removal of forests affects both carbon and water cycles.

Paving a large parking lot involves covering the soil surface with asphalt, concrete or any other materials. Soil contains millions of aerobic organisms that assist in decomposition of organic matters. Covering up the soil surface will limit the activities of these organisms and negatively affect organic matter decomposition which happens to be a major step in carbon cycle.

Acid rain occur when acidic oxides present in the atmosphere dissolve in rainwater to produce a weak acid. The acidic oxides include, oxides of sulphur, nitrogen, etc.

Eutrophication is the enrichment of water bodies by nutrients such as phosphorus and nitrogen. The enrichment causes a bloom of photosynthetic aquatic organisms and microbes. These blooms lead to high oxygen consumption from the water bodies which can eventually lead to the depletion of oxygen.

Excess nitrogen can enter the nitrogen cycle via fertilizer usage by farmers, sewage treatment plants and exhaust of vehicles. Fertilizers are rich in nitrogen (NPK) and those that are not used by crops enters the nitrogen cycle through the soil. Treated sewage also represents a rich source of nitrogen and when released into the environment, then enter the nitrogen cycle through the soil or water. Smokes emanating from vehicles contain oxides of nitrogen and these enters into the nitrogen cycle through the air.

Translation and protein synthesis is taking place at the ribosome in this illustration. Where did the original instructions for this process originate? A) RNA in nucleus B) DNA in nucleus C) tRNA in cytoplasm D) mRNA attached to ribosome

Ans.

Protein synthesis involves the process of transcription and translation. Transcription shows transfer of genetic information from the DNA present in the nucleus to RNA that gets attached with ribosome.

During translation, information present in mRNA is decoded to make a specific polypeptide chain or protein.

Thus, the correct answer is option B). 'DNA in nucleus.'

Sally's teacher asked her to classify a microscopic organism found in pond water. The FIRST characteristic Sally used to figure what kingdom the organism belonged to was A) cell type. B) cell diameter. Eliminate C) number of ribosomes present. D) chemical composition of cell wall.

Ans. (A). cell type.

All organisms are classified into three kingdoms on the basis of their cell type, which include Monera, Protista, Fungi, Animalia, and Plantae.

Monera includes single-celled, prokaryotic organisms, such as bacteria and archaea. Cells of these organisms lack true nucleus and membrane bound organelles.

Protista include mostly single-celled eukaryotic organisms, such as amoeba and euglena. Eukaryotic cells have true nucleus and other membrane bound organelles.

Fungi includes fungus and other related organisms), such as yeast and mushroom. They have eukaryotic cells, surrounded by cell wall, like plant cells but they lack chloroplasts.

Animalia includes multicellular, eukaryotic organisms such as birds, fishes, insects, and humans. Animals also have cells with membrane bound organelles, but they lack cell wall.

Plantae include all the green plants, such as angiosperms, mosses, and ferns. Cells of these organisms are surrounded by a cell wall and have chloroplasts to perform photosynthesis.

So, the first characteristic that should be used to classify the organisms is to study their cell type. Thus, the correct answer is option (A).

One of the many unique properties of water is that its solid form (ice) is less dense than its liquid form. Most substances become more dense when in solid form, because their molecules are more tightly compact. Why is this property of water so important to life on Earth?

The presence of hydrogen bond is one factor that explains the fact that ice floats over water because it has less density.

Due to this, rivers and lakes freeze from the surface whereas it is in liquid state at the bottom which allows the sea animals to survive even in colder temperatures.

Water makes up at least 70% of earth and 65% of our bodies and this property of water is essential for our lives as it maintains the survival.

In which process do producers use carbon from carbon dioxide to produce other carbon-containing molecules? A. the water cycle B. photosynthesis C. the nitrogen cycle D. respiration

Answer:

The process in which process do producers use carbon from carbon dioxide to produce other carbon-containing molecules is the Photosynthesis.

Explanation:

Photosynthesis is the process of making food by plants.

To make it, plants need chlorophyll, which is a green pigment that they have on the leaves. It is responsible for absorbing adequate light to perform this process.

This process is performed on the leaves, which are oriented towards the light. The chlorophyll of the leaves capture the sunlight. From the sunlight and carbon dioxide, the raw sap is transformed into processed sap, which constitutes the plant's food. In addition the plant produces oxygen that is expelled by the leaves.

Auxin is the molecule which is related to the phototropism of the plants. In the mutant plants, which do not have hormone auxin, do not respond to light. It activates proton pump, and leads to the decrease in the pH of the leaf. This acidification breaks cell wall structure and cell wall become less rigid, and thus, can bend towards the light, by exerting mechanical pressure.
