The complete question is as follows:
The diagram shows water molecules as solid ice at 0°C and as a liquid at 25°C. Explain why the arrangement of water molecules is different in ice and water.
Answer:
In low temperatures, hydrogen bonds between water molecules become stable as a result of the movement of these molecules are slow in low temperature which leads to the crystalline form of water due to hydrogen bond. This crystalline form is ice.
on the other hand at a higher temperature water molecules found in liquid form due to the faster and rapid movement of water molecules as hydrogen bonds keep breaking and forming in this setting.

Answer:C
Explanation:They use energy from the sun to chemically combine carbon dioxide with hydrogen and oxygen from water to create sugar molecules.
The process by which gas from the atmosphere is obtained by plants and used to build lipids is best described by option C (Gas is directly obtained by plants as part of the carbon cycle).
The carbon cycle is the process that brings about the circulation of carbon compounds in nature.
Carbon exists in nature as the gas carbon dioxide which makes up 0.03% of air.
The plants uses carbon dioxide in a process called photosynthesis to manufacture their own food (glucose).
Excess glucose produced by plants, are converted to substances such as starch and lipids, which are then stored in various parts of plant.

Organisms can form several types of symbiotic relationships. From the descriptions, determine if each of the symbiotic relationships is an example of commensalism, mutualism, or parasitism. 1. Hermit crabs protect themselves from predators by living in shells discarded by snails. 2. Ticks attach to humans in order to eat human blood. Ticks can also infect humans with Rocky Mountain spotted fever and Lyme's disease. 3. The coralroot orchid is a reddish color and is unable to photosynthesize. These orchids take carbohydrates from pine trees through connections formed between their roots and the roots of the pine trees. 4. The bullhorn acacia grows special tissues in which ants live. The ants find a safe place to live and attack any animals that attempt to graze on the acacia. 5. The Leucochloridium worm infects snails and is able to control the snail's behavior, creating a zombie-like snail. The worm forces the snail to attract predators to itself so that the worm is eaten and passed to its next host. 6. On the Galapagos Islands, there are finches that remove parasitic insects from tortoises. The finches gain a meal and the tortoises are ridded of parasites. 7. Cattle egrets follow cattle and other large grazing animals and eat the insects stirred up by cattle's hooves.
Answer:
From the questions, here are the answers.
1 is commensalism
2. Parasitism
3. Parasitism
4. Mutualism
5. Parasitism
6. Mutualism.
7.Commensalism
Explanation:
Hermit crabs protect themselves from predators by living in shells discarded by snails and Cattle egrets follow cattle and other large grazing animals and eat the insects stirred up by cattle's hooves relationship is commensalism because commensalism is a symbiotic relationship that take place between two organisms in which one benefits and the other is neither harmed or does not benefit. Hermit crabs benefit by receiving protection from snail shells and snail does not benefit and not harmed. Cattles eagret feed on insects on cattle hoolves, cattle is not harmed or does not benefit
Parasitism
2. Ticks attach to humans in order to eat human blood. Ticks can also infect humans with Rocky Mountain spotted fever and Lyme's disease. 3. The coralroot orchid is a reddish color and is unable to photosynthesize. These orchids take carbohydrates from pine trees through connections formed between their roots and the roots of the pine trees and The Leucochloridium worm infects snails and is able to control the snail's behavior, creating a zombie-like snail. The worm forces the snail to attract predators to itself so that the worm is eaten and passed to its next host are parasitism relationship because parasitism is a relationship that exists between two organisms in which the other called the predator infect , harm or cause damage to the host organism. The above are parasitism relationship because they cause damage to their host.
Mutualism
The bullhorn acacia grows special tissues in which ants live. The ants find a safe place to live and attack any animals that attempt to graze on the acacia and On the Galapagos Islands, there are finches that remove parasitic insects from tortoises. The finches gain a meal and the tortoises are ridded of parasites exhibit mutualism relationship because mutualism is a symbiotic relationship that exists between two organisms in which both benefits from the relationship. The Acasia and the ants receive protection from the relationship. The finches and tortoise benefited from their relationship.
Which of the following statements correctly describes some aspect of protein excretion in prokaryotic cells? a Prokaryotes are unlikely to be able to excrete proteins because they lack an endomembrane system. b The mechanism of protein excretion in prokaryotes is probably the same as that in eukaryotes. c Proteins that are excreted by prokaryotes are synthesized on ribosomes that are bound to the cytoplasmic surface of the plasma membrane. d In prokaryotes, the ribosomes that are used for the synthesis of secreted proteins are located outside of the cell. e Prokaryotes contain large pores in their plasma membrane that permit the movement of proteins out of the cell.
Answer:
The correct answer is option c "Proteins that are excreted by prokaryotes are synthesized on ribosomes that are bound to the cytoplasmic surface of the plasma membrane".
Explanation:
Many prokaryotes secrete proteins, particularly, extracellular enzymes that have a function outside the cells and toxins that are not needed by the cell. As any other protein, proteins that are excreted by prokaryotes are synthesized on ribosomes that are bound to the cytoplasmic surface of the plasma membrane. However, excreted proteins go to the general secretion (Sec) pathway, where they are tagged and further processed.

What happens to the temperature of the water when it begins to melt?
Answer:
When you heat ice, its temperature rises, but as soon as the ice starts to melt, the temperature stays constant until all the ice has melted.
According to the graph, the temperature of the water continues to increase during the change of state. Thus, the correct option for this question is A.
What will happen if the ice melts?When the ice melts, the level of seawater would tend to be increased. This is because solid ice has tended to change its state to liquid. And now liquid may increase the density of the seawater which ultimately rises its level.
It is noted that when the temperature reaches that 0°C. For some instances of time, it will remain the same, but as time passes it tends to increase. The same principle is seen when the temperature reaches 100°C. So, it can not be said that the temperature remains at 0°C or 100°C until the changes in state.
Therefore, the temperature of the water continues to increase during the change of state. Thus, the correct option for this question is A.

How are chemosynthetic bacteria different from photosynthetic bacteria?
A Chemosynthetic bacteria do not require water B Chemosynthetic bacteria eat tube wormS. C. Chemosynthetic bacteria require intense sunlight
D. Chemosynthetic bacteria do not need light.
Answer:
D
Explanation:
Chemosynthetic bacteria different from photosynthetic bacteria in that Chemosynthetic bacteria do not need light and the correct option is option D.
Chemosynthetic bacteria are a type of bacteria that can produce their own energy and organic compounds without the use of sunlight. They obtain their energy by oxidizing inorganic substances, such as hydrogen sulfide or methane, and using the energy released from these chemical reactions to synthesize organic molecules.
In contrast, photosynthetic bacteria, including cyanobacteria, use sunlight as a source of energy for photosynthesis. They have pigments, such as chlorophyll, that capture light energy and convert it into chemical energy through a series of biochemical reactions.
Chemosynthetic bacteria can thrive in environments with little or no light, such as deep-sea hydrothermal vents or certain underground ecosystems. They are able to utilize chemical energy sources to sustain their metabolic processes and support their growth and reproduction.
Thus, the ideal selection is option D.
