Answer:
2. The lime water turns milky in colour
3. To act as filters
4. To enable easy penetration of the root of planted crops.
See detailed explanation below
Explanation:
2. Our exhaled air principally contains carbon dioxide gas (CO2), which reacts with like water to produce a milky solution. The lime water is a solution of Calcium hydroxide (CaOH2), which chemically reacts with the C02 content of our exhaled air to form a compound called Calcium carbonate (CaCO3). Calcium carbonate is a whitish compound that appears chalky/milky.
3. Our nostrils contain a cavity called nasal cavity, which is lined with mucus (a viscous substance). The mucus helps to keep the nasal cavity wet. The hair in the nostrils also help prevent large particles in inhaled air from entering into the nasal cavity. The hair and mucus works together to filter out shirts and germs like bacteria etc from entering into the lungs.
4. Farmers loosen the soil which they plant their crops by mixing the layers of the soil. Loosening the soil encourages or promotes a deep and easier penetration of the plant roots. It also helps the soil to be properly drained and aerated i.e. penetration of water and air into the soil respectively.

The route that the sensation of taste follows is a: Primary axons pass along cranial nerves VII and IX. b: Primary neurons synapse in the nucleus solitarius. c: Secondary neurons synapse in the thalamus. d: Tertiary neurons travel to the primary gustatory cortex.
Answers
Answer:
d: Tertiary neurons travel to the primary gustatory cortex.
Explanation:
The gustatory system is a sensory system that is responsible for the taste. when the food comes in contact with the taste cells present on the tongue so these taste buds carry information to the brain about flavor of the food. The chorda tympani nerve that is present at the front of the tongue, the glossopharyngeal nerve present at the back of the tongue and the vagus nerve present at the throat area and palate are the three nerve cells which carry signals to the brain stem.

Describe the difference between a chemical and an electrical gradient. What's an electrochemical gradient? Do you think an electrochemical gradient can have conflicting component gradients?
Answers
Answer:
1) The difference between chemical gradient and electrical gradient is that chemical gradient refers to the change in concentration of an ion or molecule in a solution across a biological membrane while electrical gradient refers to the existence of an electrical potential difference that leads to the movement of charged ions towards or away from the electrical potential
2) Electrochemical gradient is the charge and ion concentration difference across a biological membrane
3) No because electrochemical gradient which consists of both an electrical and chemical gradient have a complementary effect in determining the level of the electrochemical gradient.
Explanation:
The electrochemical gradient is the gradient of the electrochemical potential and is usual for a positive and negative ion that can move across the membrane.
What is the electric gradient ?The gradient is made of two parts that are chemical which is different in solutes that can move across the membrane and have an electrical component that shows difference in changes across the membrane.
The electrostatic gradient is a potential used in an iron that can be used across the membrane. Due to unequal concertation of ions, they will move across the simple diffusion.
The electrochemical has potential in electroanalytical industries as batteries and fuels. The gradient has contrasting components as change across the membrane.

The answer is geothermal (b)
The correct answer is B. Geothermal.
This is true because geo relates to the earth and thermal relates to heat.
When you put those two words together, it means heat from the earth.
A is incorrect since the energy sources comes from the fission or splitting of atoms.
C is incorrect since solar energy relates to heat or energy from the sun.

A lichen is an organism that structurally appears to be a single organism. But a lichen is actually two different organisms—a fungus and green algae—living together as one organism. The fungal partner derives its nutrition from the photosynthesizing algae. How does a lichen differ in its photosynthetic activity from Elysia chlorotica, the sea slug that’s considered to be a photosynthesizing animal? A. In lichens, the fungi photosynthesize on their own, while Elysia chlorotica forms a relationship with a photosynthesizing plant. B. In lichens, the relationship with the algae lasts throughout the life cycle, but in Elysia chlorotica, the relationship occurs only during the immature juvenile stage of the slug’s life cycle. C. Lichens can photosynthesize only because of the living algal partner, while Elysia chlorotica incorporates chloroplasts from algae into its cells. D. In lichens, the association between the fungi and algae is permanent, while Elysia chlorotica associates with a photosynthesizing organism only when it requires food.
Answers
Answer:
Option C
Explanation:
Lichens can photosynthesize only because of the living algal partner, while Elysia chlorotica incorporates chloroplasts from algae into its cells.
Elysia chlorotica which is a form of sea slug feeds on a specie of the genus Vaucheria (an algae) and then retains only the chroloplasts of these algae which it uses for its own supply of energy.
The algal partner in lichens is the photosynthesizing partner. It produces food and this is its role in the relationship. The fungi are heterotrophs and cannot photosynthesize food. The fungi contribute to the relationship my absorbing mineral and water and presents it to the algae.
Answer:
Lichens can photosynthesize only because of the living algal partner, while Elysia chlorotica incorporates chloroplasts from algae into its cells.

Modern domesticated pigs are descendants of the wild boar(Susscrofa). Through the domestication process, human have artificially selected for certain traits. Identify two of these traits, and briefly explain how they benefit modern society. Be sure to identify the trait, explain why it was artificially selected and how it benefits modern society.
Answers
Answer:
Meat for food and small size for pets
Explanation:
Artificial selection is the process by which humans control desirable phenotypic characteristics in plants and animals by applying selective breeding techniques to perpetuate these traits in the population. A example of artificial selection includes the process of domestication of modern pigs (Sus domesticus). It has been shown that the modern pigs derived from the wild boar (Sus scrofa), which were domesticated separately 9,000 years ago in China and Western Asia. For example, by artificial selection, humans have domesticated moderns pigs to use them as livestock for direct consumption (i.e., for their meat). Moreover, there are pig populations that have been artificially selected as pets (e.g., miniature Vietnamese Pot-Bellied pigs).

A person cannot produce several types of proteases. Name the problem this specific person probably has and explain why.
Answers
Answer:
The person have excess amount of proteases and when this happen, the person will protein breakdown in the body or lack of protein in the body which can affect most of the organs in the body.
Explanation:
Under normal conditions in the body, blood and body tissues have a specific potent enzyme called proteases. Protease help in the breakdown of protein in the body and play important roles in defending or fight against incoming infections and inflammatory processes in the body .There is need for thslese proteases to be regulated or control because overactivity can lead to protein destruction which will lead damage of different body organs. In order to control this, blood and other tissues in the body posses enzymes with protease inhibitory activity, these enzymes help to prevent its from undergoing excessive action and potentially harmful effects.

Gene expression patterns can be used to test hypotheses based on morphology. For example, the regulatory gene Bapx1 is expressed in the hinge of the developing lower jaw in fishes and reptiles. Where would you predict Bapx1 expression to occur in mammals?
A. in the developing cheekbone
B. in the developing lower jaw
C. in the mature lower jaw
D. in the developing ear bones
Answers
Answer:
The correct answer is option D. "in the developing ear bones".
Explanation:
The developing lower jaw of fishes and reptiles has a variety of bones that are joined together, forming the mandible that they use to eat their preys. Some bones in the developing lower jaw of fishes and reptiles are equivalent to the developing ear bones of mammals. Therefore we can predict that the Bapx1 expression in mammals will occur in the developing ear bones. About this evolutionary relationship, scientist Zhe-Xi Luo of the Carnegie Museum of Natural History in Pittsburgh states "Reptiles have [a] jaw full of ear bones from mammals and mammals have an ear full of jawbones of reptiles".
