Minerals can be classified based on cleavage or fracture. These two properties refer to the way in which a mineral tends to break. Cleavage is an orderly breakage in well-defined planes. It means that the broken piece of mineral will have flat and smooth sides. Fracture is a random breakage. If a mineral breaks with rough, random, uneven surfaces, it is said to have fractured. Because each of your mineral samples have already been broken from another, larger piece of a mineral, you should be able to tell if it has cleavage or fractures by looking at its sides. Of your 10 minerals, identify three that experienced cleavage. a cube-shaped gray mineral with smooth faces and sharp edges,a rust-colored mineral with a rough, uneven surface
Answers
The cube-shaped gray mineral with smooth faces and sharp edges likely experienced cleavage.
Cleavage is characterized by orderly breakage in well-defined planes, resulting in flat and smooth sides on the broken piece of a mineral. The cube-shaped gray mineral described with smooth faces and sharp edges fits this description. The smooth faces and sharp edges suggest that the mineral broke along specific planes, indicating cleavage.
On the other hand, the rust-colored mineral with a rough, uneven surface is more likely to have experienced fracture. Fracture refers to random breakage, resulting in rough, random, and uneven surfaces on the broken piece of a mineral.
It's important to note that visual inspection alone may not always provide definitive information about the cleavage or fracture of a mineral.

Which biomolecule determines a person's ability to clot blood properly?
A- Glycogen
B- Lipids
C-Carbohydrates
D- Nucleic Acids
Answers
Answer:
D- Nucleic Acids
Explanation:
Blood clotting is a process whereby a person's blood coagulates due to the formation of a white fibrous protein substance called FIBRIN. The essence of blood clotting is to prevent excessive flow/waste of blood when a blood vessel is wounded.
However, certain substances are needed for this process of blood clotting to occur in our body. Some individuals lack this substances and hence bleed continuously during injury, a condition known as HEMORRHAGE. The substances such as FIBRIN, a protein needed for blood clotting is encoded by GENES which makes up DNA (a type of nucleic acid).
Therefore, NUCLEIC ACID biomolecules determines a person's ability to clot blood properly because nucleic acids make up DNA, which contains segments (genes) that encode the synthesis of proteins (fibrin) needed for blood clotting to occur. Hence, it all boils down to NUCLEIC ACIDS.

on a phylogenetic tree, a grade is a: group of answer choices a slice through a phylogenetic tree that shows organisms of the same evolutionary complexity a slice through a phylogenetic tree that shows all the organisms that lived at the same point in time. all the branches off a stem of a phylogenetic tree all the organisms in a single clade
Answers
In a phylogenetic tree, a grade refers to a group of organisms that share a similar level of evolutionary complexity.
A grade in a phylogenetic tree is a term used to describe a grouping of organisms based on their evolutionary complexity or level of development. It represents a horizontal slice through the tree, encompassing organisms that have reached a particular stage of evolutionary advancement.
Grades are determined by specific characteristics or traits shared by the organisms within the group. These traits may include anatomical features, physiological adaptations, or behavioral patterns. Unlike a clade, which represents a group of organisms sharing a common ancestor and all of its descendants, a grade does not necessarily include all descendants of a common ancestor.
Instead, it focuses on organisms that have independently evolved similar characteristics or adaptations, regardless of their ancestral relationships. Grades provide a way to categorize organisms based on their relative level of complexity and track their evolutionary progress through time.

The biomass pyramids for phytoplankton and trees in their respective environments are _______. a. both inverted b. the same c. opposite d. both normal please select the best answer from the choices provided a b c d
Answers
The biomass pyramids for phytoplankton and trees in their respective environments are opposite.
In the field of ecology, a biomass pyramid can be described as a pyramid that represents the biomass i.e the amount of living tissue at each trophic level in an ecosystem.
Usually, the biomass of producers is the greatest in an ecosystem and it decreases while going up at each trophic level. Producers such as trees are usually higher in number and have a larger life span. Hence, their biomass is greater than consumers.
However, the case is the opposite in the case of phytoplanktons. If phytoplanktons are the producers in an ecosystem, then the pyramid of biomass is inverted.
This is because phytoplanktons have a short life span and also are very tiny having little mass. As compared to phytoplanktons, the consumers of such an ecosystem have a greater mass and life span. Hence, the pyramid for trees and phytoplanktons is the opposite.

The force exerted outward on a plant cell wall by the water contained in the cell is called______pressure.
Answers
The force exerted outward on a plant cell wall by the water contained in the cell is called Turgor pressure.
Turgor pressure, which affects bacteria, fungus, and plants, often results from the osmotic movement of water. Moreover, protists with cell walls exhibit the phenomena. Animal cells do not use this method because they lack a cell wall, which would allow excessive pressure to cause the cell to lyse.
Cell walls and vacuoles are two essential components that plants require to maintain the ideal mechanism for regulating turgor pressure inside the cells.
Turgor pressure serves the important purpose of encouraging cell volume expansion, and the larger the turgor pressure, the larger will be the leaf expansion. Osmotic potential and water potential both influence how much turgor pressure is present.

During the winter, many ponds and lakes freeze over. What properties of water allow the organisms to survive underneath the ice? Explain in detail how this happens.
Answers
The characteristic of water that allows organisms to survive in water during winter is that ice is less dense than liquid water.
Ice is less dense than liquid water, which is why it floats. This feature is important because it prevents ponds, lakes, and oceans from freezing and allows life beneath the surface of the ice to continue to thrive.
The hydrogen bonds between water molecules give the water a better ability to retain heat than many other substances. As the temperature increases, the hydrogen bonds between the water are broken and constantly renewed, so that the overall temperature remains stable even as energy is added to the system. This allows many forms of aquatic life to survive the cold season. If it were denser than water, it would freeze and sink repeatedly until the entire lake froze.

Is the structure of DNA and replication of the DNA basically the same or basically different in bacteria and eukaryotes? Would a plant be able to replicate bacterial DNA that was inserted into the plant genome? Justify your answer.
Answers
The structure of DNA and the replication of DNA is fundamentally the same in both bacteria and eukaryotes. However, there are a few differences between the two that could result in significant variations. In both eukaryotes and bacteria, DNA replication begins at the origin of replication and proceeds in both directions.
DNA replication in eukaryotes, on the other hand, occurs in a compartment known as the nucleus, whereas DNA replication in bacteria occurs in the cytoplasm. Additionally, bacteria have a single origin of replication, whereas eukaryotes have many origins of replication.A plant would be able to replicate bacterial DNA that was inserted into its genome since the DNA structure is conserved throughout the animal and plant kingdoms.
The bacterial DNA will replicate, and the plant cells will produce bacteria proteins as a result of the inserted bacterial DNA, which will then perform its bacterial functions. The DNA's coding sequences and structural features are conserved between bacteria and plants, despite the fact that their regulatory sequences differ, which allows the DNA to be replicated and utilized in plants.
