Answer: C. competition
Explanation:
Competition can be define as the ecological relationship in which one species is more superior over the other in deriving resources. In competition usually one species live and the population of other species may either decrease in abundance, or may extinct.
The release of toxic chemicals by the plants to harm nearby plants is an example of competition. This is because of the fact that the plants may face competition with other plants for resources such as sunlight, water and minerals. Therefore, a physiological response will be generated inside the plants so as to kill the neighboring plants.
In a faraway city called Grant City, the main export and production product is the steel widget. Everyone in the town has something to do with steel widget making and the entire town is designed to build and export widgets. The town hall has the instructions for widget making, widgets come in all shapes and sizes and any citizen of Grant can get the instructions and begin making their own widgets. Widgets are generally produced in small shops around the city; these small shops can be built by the carpenters’ union (whose headquarters are in town hall).
After the widget is constructed, they are placed on special carts which can deliver the widget anywhere in the city. In order for a widget to be exported, the carts take the widget to the postal office, where the widgets are packaged and labeled for export. Sometimes widgets don't turn out right, and the "rejects" are sent to the scrap yard where they are broken down for parts or destroyed altogether. The town powers the widget shops and carts from a hydraulic dam that is in the city. The entire city is enclosed by a large wooden fence, only the postal trucks (and citizens with proper passports) are allowed outside the city.

Sulfur is a nonmetalic mineral that has a density of 2 g/cm3. The volume of a sample of sulfur was measured to be 5.0 cm3. What is the mass of the sample?
The mass of a 5.0 cm³ sample of sulfur with a density of 2 g/cm³ is 10 grams. The calculation involves simply multiplying the given density by the volume.
Explanation:The question is asking about calculating the mass of a sample of sulfur given the density and volume. The density of a substance is the ratio of the mass of a sample of the substance to its volume. The density of sulfur is given as 2 g/cm³. To find the mass of the sample, you simply multiply the density and volume. In this case, the volume is 5.0 cm³, so the mass is 2 g/cm³ x 5.0 cm³ = 10 grams.
This is based on the general principle that density = mass/volume. In this situation, sulfur is a nonmetallic mineral, and like many nonmetals, it has an oxidation state of 2-. Sulfur can react with most metals and readily forms the sulfide ion, S²-, further indicating its nonmetallic nature.

Asexual reproduction in the parent cell will result in offspring with
A) similar genetic information.
B) half the genetic information.
C) double the genetic information.
D) four times the genetic information.
Correct answer: A). Similar genetic information.
Asexual reproduction is a mode of reproduction, which involves one parent and gives offspring that are genetically similar to each other and to their parents. It does not involve the fusion of male and female gamete.
It allows the plant to reproduce quickly, as a result of that the parent plant is compete-ting with their offspring for the same nutrient, sunlight, and space.
Example: Binary fission, fragmentation, vegetative propagation.
The complete complex of DNA and protein in a cell is known as _________ .
to meet cellular needs for food,water,energy,waste removal,multicellular organisms have developed various specializations,such as organs,and organ systems.
Answer:
The correct answer will be- true and structural specializations
Explanation:
The evolution of life on earth has suggested that life has moved from the simplicity to complexity or from single-celled organism to multicellular organism.
This multi-cellularity is achieved through the property of called cellular differentiation and specialization. as the cellular complexity increases, therefore, cellular demands like the use of energy, food, water and other variables increased.
This lead to the formation of the organ and organs system specializes to perform specific functions like the digestive system and another biological system.
Thus, true and structural specializations are the correct answer.
Answer: the answer is Structural

two ways water travels from land to enter the ocean
Final answer:
Water enters the ocean from land via runoff and groundwater flow, integral parts of the water cycle.
Explanation:
Two ways water travels from land to enter the ocean as part of the water cycle are through runoff and groundwater flow. Runoff occurs when water from precipitation like rain or melting snow flows over the surface of the land and into rivers, lakes, and eventually reaches the ocean. Groundwater flow refers to water that infiltrates the soil, becoming groundwater, which moves through the ground and discharges into the ocean, completing the cycle.
Which one of these is not an example of intercellular communication? Question 5 options:
A message travels between gap junctions.
An electrical signal causes muscle cells to contract together.
A message is distributed across plasma membrane.
A molecule stimulates a target cell via a receptor.
PLEASE HELP!
*Please and Thank You*
It is C. A message is distributed across the plasma membrane.
The correct answer is (C) A message is distributed across plasma membrane.
Intercellular communication means the communication that takes place between two cells, gap junctions, target-receptor. This means the message is transferred between two cells and then carry forward by other cells like a cascade or signal transduction. When a message is transferred across plasma membrane this means that no other cell is involved in it. The message is transferred from one organelle to other within the cell. Inter cellular response is not restricted only upto a single cell.
