Explanation:
IMPORTANCE OF TRANSPORT MECHANISMS IN CELLULAR PROCESSES.
Explanation:
Small substances constantly pass through plasma membranes. Active transport maintains concentrations of ions and other substances needed by living cells in the face of these passive movements. Much of a cell's supply of metabolic energy may be spent maintaining these processes.
What are characteristics that are unique to wetlands?
Answer:
Wetlands must have one or more of the following three attributes: 1) at least periodically, the land supports predominantly hydrophytes; 2) the substrate is predominantly undrained hydric soil; and 3) the substrate is saturated with water or covered by shallow water at some time during the growing season of each year.
Explanation:The minimum essential characteristics of a wetland are recurrent, sustained inundation or saturation at or near the surface and the presence of physical, chemical, and biological features reflective of recurrent, sustained inundation or saturation.
How is energy released from ATP?
ANSWER CHOICES IN THE PIC
Answer:
Explanation:
When one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and ATP is converted to adenosine diphosphate (ADP). Likewise, energy is also released when a phosphate is removed from ADP to form adenosine monophosphate (AMP).

nerve fibers are insulated from one another by __________.
Answer:
endoneurium
Explanation:
The endoneurium is a layer of connective tissue composed of endoneurial cells that surround and protect the myelin sheath of each myelinated nerve fiber.
nerve fibers are insulated from one another by endoneurium.
What are nerve fibers and their composition?A nerve fiber is a long axon from a nerve cell (neuron muscle). The body of the nerve cell is anatomically located either inside the ganglia of the peripheral nervous system or within the central nervous system.
The ganglionic neurons' axons that travel from the retina's vitreal surface to the optic disc make up the nerve fiber layer. These axons are not myelinated until they reach the optic disc and break through the sclera. The optic disc's white color is a result of oligodendrocytes' myelination of them at this point. They help in the communication of two nerve fibers.
Thus, nerve fibers are insulated from one another by endoneurium.

How do cells in an embryo become different types of cells?
Answer:
The zygote divides into multiple cells in a process known as cleavage, triggering the beginning of embryonic differentiation. During cleavage, the zygote divides but maintains its size in the process. ... Cells in these three layers will give rise to different parts of the organism. The endoderm eventually becomes the gut.

because one original strand of the double-stranded helix is found in each daughter molecule, the replication process is called
Because one original strand of the double-stranded helix is found in each daughter molecule, the replication process is called semiconservative.
Replication is the process by which a DNA molecule generates two identical to itself, and is key in cell reproduction.
All cells in the body must have the exact same genome (as in asexual reproductive organisms, which are practically clones of each other) and this is achieved through replication.
The process consists of separating the two strands of DNA, each of which will function as a template to synthesize a new one.
That is, each of the two strands of DNA serves as a template to synthesize a new complementary strand of the template.
In the end, two DNA molecules are formed, each of the two DNA molecules has a new chain and one original strand, this mode of replication is called semi-conservative.
Therefore, we can conclude that because one original strand of the double-stranded helix is found in each daughter molecule, the replication process is called semiconservative.

what is the name used to refer to the clogged xylem tissue?
The name used to refer to the clogged xylem tissue is heartwood in contrast to sapwood, a term for the dead, clogged xylem cells near the center of a tree. Heartwood has been the tree as the main column of support.
What is xylem?Xylem has been defined as the vascular bundle which has been used to transport water and other minerals from the root part to other parts of the plant. The main function of the xylem and phloem is to transport water and minerals from root to other parts of the plant.
The last common ancestor of the gymnosperms and angiosperms possessed the same characters such as the pollen, seeds, and the vascular tissue.The gymnosperms are a group of plant that are known as seed- producing plants such as Ginkgo, gnetophytes, cycads etc.
Angiosperms has been the plant that produces flowers and having seeds enclosed within their fruit. Gymnosperms have no production of flowers and fruits and they contain bare seeds on the surface of their leaves.
Therefore, The name used to refer to the clogged xylem tissue is heartwood in contrast to sapwood, a term for the dead, clogged xylem cells near the center of a tree. Heartwood has been the tree as the main column of support.

What are the roles of the nucleus, cytoplasm, mitochondria, and the cell membrane in eukaryotic cells? in your own words nothing from the internet
Answer:
What are the roles of the nucleus, cytoplasm, mitochondria, and the cell membrane in eukaryotic cells?
Explanation:
1.The cell membrane holds the cell's internal contents from its environment
2.the nucleus, the cell's "brain", holds the cell's DNA in the form of chromosomes, and makes protein codes that tell the other organelles to function in a certain way once the codes are made into literal proteins and passed around the cell
3.The cytoplasm is the gelly fluid inside the cell. It is the place for chemical reaction, and provides a place where other organelles can operate within the cell properly, and the cytoplasm keeps the cells from moving around.
4. The main job of the mitochondria is to convert nutrients into energy through cellular respiration, making ATP. the mitochondria are known as the powerhouse of the cell. In addition to supplying energy, the mitochondria is involved in a range of other processes,like signalling, cellular differentiation, cell death, as well as control of the cell division cycle and cell growth.

How to make bacteria as a treatment for sewage waste
Answer: Bacteria break down organic material in wastewater and form the floc that settles and separates solids from liquids. Controlling F/M ratio–a vital component to creating a favorable environment for wastewater bacteria–can be accomplished through the use of bioremediation products. Bacteria account for 95% of the microorganisms in wastewater. They are single-celled microorganisms that are classified based on their response to oxygen.
Aerobic bacteria use oxygen, which is added mechanically, to break down wastewater contaminants, converting it into energy. Bacteria use this energy to grow and reproduce. Anaerobic bacteria obtain oxygen from their food source. As anaerobic bacteria break down sludge, they produce methane gas. This methane gas can be used as an alternative energy source, called biogas, to fuel the wastewater treatment process. Anaerobic bacteria can also be used to lower the amount of phosphorus in the effluent. Although they prefer oxygen, facultative bacteria can switch between aerobic and anaerobic forms in response to their environment.
Explain why the shape of an enzyme is important to its function.
Answer:
The shape of an enzyme is very important because it has a direct effect on how it catalyzes a reaction.
Each enzyme is folded into a shape that allows the substrate(s) to fit into the active site, which is where the reaction occours. Other substrates do not fit into this active site. This is why each enzyme can only catalyse a specific reaction
