B. The oldest crust is closest to the mid-ocean ridge.
Explanation;Seafloor spreading refers to the process by which new oceanic crust forms along a mid-ocean ridge and older oceanic crust moves away from the ridge. Seafloor spreading occurs at the mid-oceanic ridge where the divergent boundaries cause two plates to move away from each other resulting to the spreading of the sea floor.As the divergent plates move apart, new materials wells up and then cools at the edge of the plates. Seafloor spreading is important as it helps explain the continental drift in support of the theory of plate tectonics.The cells in your body need nutrients and other materials to stay alive.

What is a cell?Cells are the fundamental building blocks of all life. Various of cells make up the human body. They give the body structure, absorb nutrients from food, and convert those nutrients into energy.
The cell, first discovered by Robert Hooke in 1665, has a rich and interesting history that has led to many of today's scientific advances.
Cells, as we've seen, require a constant supply of energy to generate and maintain the biological order that keeps them alive.
This energy is derived from the chemical bond energy in food molecules, which serve as fuel as a result.
To survive, cells in the body require nutrients and other materials. The materials must be dissolved in fluid before they can be used by cells.
Thus, the correct option is c.

A marine biologist was taking photographs of ocean animals. One animal had tentacles with long stinging cells on the end. Which of these groups did the animal belong to?
A.
mollusks
B.
cnidarians
C.
arthropods
D.
sponges
Final answer:
The animal observed by the marine biologist, characterized by tentacles with long stinging cells, belongs to the group of (option B.) cnidarians. This group, which includes jellyfish, corals, and sea anemones, uses cnidocytes with nematocysts to immobilize prey.
Explanation:
A marine biologist observed an animal with tentacles possessing long stinging cells at the end, indicating that the animal belongs to the group cnidarians. Cnidarians, a phylum that includes organisms like jellyfish, corals, and sea anemones, are known for their unique cells called cnidocytes, which contain nematocysts (stingers). These specialized cells are designed to immobilize prey with toxins, allowing cnidarians to catch their food effectively. The presence of tentacles with stinging cells is a distinctive feature of cnidarians, distinguishing them from other groups such as mollusks, arthropods, and sponges.

Please select the best answer from the choices provided
T
F
The statement "The chaparral biome has little biodiversity and is home to only a few well-adapted species" is false.
What is Chaparral biome?Some Chaparral ecosystems (those with a low scrubby brush) are very similar to the desert scrub biome, but Chaparral occurs primarily on the coast.
Even though it appears to be true, it is not because of the stiff and dry environment of the desert biome. The Chaparral biome, on the other hand, receives more rainfall, which explains why there are so many distinct plant and tree species, as well as animals.
Shrubland biomes include the chaparral and savanna biomes. A biome is an ecological environment made up of numerous ecosystems that interact, exchange information, and are sometimes regarded as interdependent.
Therefore, the statement is false.

In sexual reproduction, offspring are genetically different from the parents. This is because
combined genes are received from both parents.
Offspring are genetically different from their parents in sexual reproduction due to crossing-over, independent assortment during meiosis, and the random union of gametes during fertilization, leading to genetic variation.
Explanation:In sexual reproduction, offspring are genetically different from the parents due to several key mechanisms. Genetic variation is the hallmark of sexual reproduction, which results in offspring with unique genetic makeups. This genetic diversity arises from processes like crossing-over and independent assortment during meiosis, along with the random union of gametes during fertilization. This diversity is crucial for the survival of species as it allows them to better adapt to changing environments and avoid the pitfalls of inbreeding.

When walking through the woods Adam and Alise saw many mushroom-like organisms growing out of logs that were laying on the ground. These logs were pieces of trees that had either completely fallen down or had broken off of the larger tree. What did Adam and Alise really see?
A. The mushrooms were only anchored to the dead logs and were undergoing photosynthesis.
B. The mushrooms were helping the trees to stay alive.
C. The mushrooms were decomposing the dead tree logs.
D. The mushrooms and tree logs were exchanging genetic material.
Answer: Option C
Explanation:
The mushrooms belongs to the family of fungus. These are natural decomposers that helps in cleaning of the environment. They feed on the dead and decaying organic matter.
Feeding on the dead and decaying organic matter provides food to mushroom and helps in decomposing the matter and adding nutrients back into the soil.
hence, Adam and Alise saw that mushrooms were decomposing the tree log.

Giant land tortoises of the Galapagos Islands have long necks as a result of natural selection, giving them a survival advantage in environments where food is scarce and positioned higher. Over time, long-necked individuals are more likely to survive and reproduce, passing on this advantageous trait.
The giant land tortoises of the Galapagos Islands and the sequoias of California possess some of the longest lifespans of any organisms on Earth. This indicates that they likely employ a strategy of natural selection, where traits beneficial for survival in their environments are passed down through generations. For the Galapagos tortoises, a notable example is the variation in neck length. Tortoises with longer necks were 'selected' in environments where food sources were higher off the ground. During droughts or in areas with sparse vegetation, these tortoises could access food that short-necked tortoises could not, thus having a better chance of survival and reproduction. Over time, the trait of having a long neck would become predominant in the population due to this selective advantage.
