Over time what could happen to an underwater island that forms near a mid-ocean-ridge
Final answer:
An underwater island near a mid-ocean ridge may evolve over time; starting as a fringing reef, it can develop into a barrier reef, lagoon, and eventually an atoll due to sea-level changes and land subsidence. Volcanic activity at mid-ocean ridges could also lead to the emergence of new islands from seamounts.
Explanation:
Over time, an underwater island near a mid-ocean ridge may undergo significant changes due to factors such as sea-level changes, tectonic subsidence, and volcanic activity. Initially, a fringing reef could form around the island. If the sea level remains stable and the land doesn't subside, the reef might not evolve further. However, if the land undergoes subsidence, the reef may grow upwards, eventually forming a barrier reef and then a lagoon as the island sinks.
Ultimately, if the island submerges completely, an atoll may emerge. Separately, ongoing volcanic activity associated with mid-ocean ridges can lead to the creation of new seamounts, which might eventually break the ocean surface to become a new island. Additionally, the constant accumulation of biogenic sediments could potentially deform the oceanic crust, potentially causing new volcanic activities.
a biologist counts the number of zebras in a population each year, and notices an increase in the zebra population. which describes the biologists actions?
graphing
inference
observation
interfacing
The correct answer is observation.
Observation is defined as noticing the process to gain information.The scientists keeps on observing the population of zebra each year and he notices an increase in population and this change was noticed by the scientist because he was observing the change in number of zebra every year.
A species becoming dependent on another species is
co-adaption is the answer
Is the stomach inferior or superior to the diaphram
The stomach is arranged substandard compared to the diaphragm, meaning it is situated beneath the stomach in the human body. This situating isolates the thoracic pit from the stomach pit.
The muscular organ known as the diaphragm divides the thoracic cavity, which is home to the heart and lungs, from the abdominal cavity, which is home to the stomach and other digestive organs. This implies that the stomach is underneath the stomach in the human body. The cardia, fundus, body, and pylorus are the four main parts of the stomach. The cardia associates with the throat and is likewise found mediocre compared to the stomach. The vault formed fundus sits above and to one side of the cardia yet at the same time stays underneath the stomach.What Happens when a ATP loses a phosphate group

Which transport process does the cell use to direct the contents of vesicles out of the cell membrane?
A. Endocytosis
B. Diffusion
C. Exocytosis
D. Passive transport
The right option is; C. Exocytosis
Exocytosis is the transport process that the cell uses to direct the contents of vesicles out of the cell membrane.
Exocytosis is a type of active transport in which substances are moved from within a cell to the external part of the cell with the use of cellular energy. In this process, membrane enclosed vesicles that contain cellular substances are moved to the cell membrane. The vesicles join with the cell membrane and their contents is released out of the cell membrane.
The R groups of amino acids located on the surface of protein molecules in the interior of biological membranes are ...?
The R groups of amino acids located on the surface of protein molecules in the interior of biological membranes are typically hydrophobic. These nonpolar R groups are compatible with the hydrophobic environment of the membrane's lipid bilayer.
Amino acids are the building blocks of proteins and differ from one another by their R groups, or side chains. The chemical properties such as size, polarity, and charge of these R groups determine their interactions and positioning within a protein structure. For amino acids located within the membrane, the R groups must be able to interact with the nonpolar lipid bilayer, which means they are generally hydrophobic. This is because the interior of biological membranes is a nonpolar environment, and hydrophobic R groups will seek to be in this environment to lower the system's free energy. The arrangement of amino acid R groups in proteins contributes to the overall shape and function of the protein, and in the case of membrane proteins, it allows them to stably exist within the lipid bilayer without disrupting the membrane's structural integrity.
if all cells in a multicellular organism have the same set of dna what accounts for the differences among different types of cells in a multicellular organism
Final answer:
Different types of cells in a multicellular organism have the same DNA but express different genes, resulting in differences in characteristics and functions among them.
Explanation:
All cells in a multicellular organism have the same set of DNA. However, the differences among different types of cells in a multicellular organism are due to the expression of different genes in the DNA. Each cell only 'reads' the portions of DNA that are relevant to its function. This unique genetic expression of each cell is what leads to the differences in characteristics and functions among different types of cells.
Cells in a multicellular organism differentiate into various types due to the selective expression of genes, even though they all contain the same DNA.
Explanation:Despite all the cells in a multicellular organism containing the same set of DNA, they differentiate into various types of cells with distinct functions and characteristics. This differentiation is a result of gene expression where different genes are turned 'on' or 'off' in each cell. Similar to how actors in a movie all have the same script but only read their parts, cells only 'read' the portions of DNA that are relevant to their roles. As cells differentiate, they not only change in size and shape but also in function, metabolic activity, and more due to the unique genetic expression of each cell type. Even in unicellular organisms, gene expression can vary in response to environmental conditions.
