Answer:
Subgranular Zone.
Explanation:
Subgranular Zone is the region in the brain where neural stems are located. These neural stem cells are found in two zones of the dentate gyrus which is a part of the hippocampus in the brain, as well as in the striatum that is the part of the basal ganglia located deep within the cerebral hemispheres. So according to this information we can conclude that Subventricle Zone is the region where Neural stems cells are not located.

why is studying climate change a scientific challenge? ( please be specific and
go into depth)
Answer:
Climate change is already happening: temperatures are rising, drought and wildfires are starting to occur more frequently, rainfall patterns are shifting, glaciers and snow are melting and the global mean sea level is rising. These ever-changing trends mean that scientists have to be well acquainted with all this which requires a great deal of understanding and patience.
The political interests in research often limit the results and many a time misleading
Data for climate research is in many instances difficult to access, often at a price, and according to the source and type of data, the formats for retrieval can be very different. In addition, data may not be available for the same time and space scales. There is often an incompatibility between socio-economic and physical data, both necessary for climate modeling efforts because data collection is generally carried out by different agencies for different purposes. This means scientists have to analyze this data as useful and then research on it.

Why do negative essay results not always mean the molecule is absent
Answer:
The concentration of the molecule may be too low to be detected
Explanation:
Negative essay results do not always mean the molecule is absent because the amount or percentage of the molecule to be detected could be too less to detect.
What are the negative assay results?
False-negative blocks haven't received as much attention as false positives, but they can lead to misdiagnosis and improper treatment candidate selection. Based on the failure of local anesthetic infiltration to relieve the pain from facet joint capsular distention, research on 15 volunteers who had MBBs with local anesthetic or saline and capsular distention estimated the rate of false-negative blocks to be 11%.
It was determined that "aberrant innervation" was a likely explanation for some instances of unsuccessful RF denervation in IA block responders. Vascular uptake is regarded to be one of the main sources of false-negative blocks. According to reports, this can vary from 6% to 30% per level. rates of 3.9% at cervical levels, 3.5% at lumbar levels, and 0.7% at thoracic levels, according to one research.
According to one study, even if the needle is relocated when vascular uptake happens, analgesia will only be experienced 50% of the time. Digital subtraction angiography has been demonstrated to increase the detection rate and is the most reliable method of identifying vascular uptake. Failure to distinguish between procedure-related discomfort and baseline pain, as well as missing a target nerve or nerves, are other potential reasons for false-negative blocks.
Therefore, a false negative result could be the result of low concentration.

Which of the following does NOT affect the flow of groundwater through an aquifer ? a. porosity C. gradient b . chemical weatheringd. permeability
Answer:
b . chemical weathering
Explanation:
Chemical weathering is not affected the flow of groundwater through an aquifer but affect by the porosity and permeability. The rate of groundwater flow is controlled by two properties of the rock which are porosity and permeability. Porosity is the percentage of void space in a rock while on the other hand, Permeability is the quality of being permeable means able to be penetrated or passed through by a liquid or gas.
Proteins secreted by Gram-negative cells face multiple obstacles, including _____. Multiple choice question. moving across the periplasmic space underlying the thick peptidoglycan layer of the cell wall moving across the plasma membrane moving across the plasma membrane and the thick peptidoglycan layer of the cell wall moving across both the plasma membrane and the outer membrane
Answer:
moving across both the plasma membrane and the outer membrane
Explanation:
Gram-negative bacteria are bacteria that have a plasma membrane, a thin peptidoglycan layer, and an outer membrane (the space between the plasma membrane and the outer membrane is known as periplasm). Moreover, Gram-positive bacteria exhibit neither outer membrane nor periplasmic space and are surrounded by thick layers of peptidoglycan. Gram-negative bacteria have developed different protein secretion systems (types I–VI and type VIII) in order to secrete proteins into the extracellular space. For such purpose, the XcpQ protein (which is an outer membrane protein from the secretin family) participates in different transport processes in Gram-negative bacteria.

Why do identical twins have some DIFFERENCES?
A. The same genes are expressed because of their environment.
B. Different genes are expressed due to their environment.
C. Their DNA is different.
Answer:
B. Different genes are expressed due to their environment.
Explanation:
I think it's this one because it makes the most sense, but I'm still not sure sorry
Answer:
B. Different genes are expressed due to their environment.
Explanation:
Some identical twins can have different heights and weights. This is because height and weight are controlled by what you eat as well your DNA. Differences in diet can start earlier than you might imagine. When the twins are growing inside the uterus, there can be differences in how well they connect to the placenta.
The acceleration of an object is measure by its change in velocity per unit time. The equation for acceleration is: a =v/t. Acceleration is represented by 'a'. Velocity is represented by 'v'. Time is represented by 't'. Rearrange the equation to solve for time.
Answer:
t=v/a
Explanation:
To solve for Time
Since acceleration is change in velocity/time
a=v/t
Cross multiply
a×t=v
at=v
Divide both side by a since we want to find Time
at/a=v/a
t= v/a
As surface water in a lake cools from 4 °C to 0 °C, the water expands and becomes less dense. Why is this change in the water beneficial to the organisms living in the lake? As the water cools to freezing, spaces form between water molecules, providing microhabitats for small organisms. Frozen surface water insulates the water below it, maintaining a habitat where organisms can overwinter. Cooler water is less viscous than warmer water, making it easier for organisms to move through the water. Less dense water holds more dissolved compounds, keeping water from freezing so organisms survive winter.
Answer:
As the water cools to freezing, spaces form between water molecules, providing microhabitats for small organisms.
Explanation:
This change in the water is beneficial to the organisms living in the lake because the water which freezes formed spaces between water molecules, that providing microhabitats for small organisms. The cold temperature causes formation of ice crystals on the surface of water which work as an insulator whereas the lower part of the water remain warm and the organisms can survive in that environment.

What type of RNA acts as a temporary copy of DNA's instructions and provides details on how to assemble a polypeptide
chain?
Answer:
messenger RNA (mRNA)
Explanation:
mRNA or messenger RNA is one of the three types of RNA molecules (the other being tRNA and rRNA) that is specifically responsible for carrying genetic information previously encoded and stored in the DNA into the ribosomes for translation to occur.
The process of translation results to the synthesis of amino acid sequences, which make up a polypeptide. Hence, it can be said that mRNA is that type of RNA that acts as a temporary copy of DNA's instructions and provides details on how to assemble a polypeptide chain.

Your teacher will grade your responses to questions 24 and 25 to ensure you receive proper credit for your answers. Identify the systems that move your body, and explain how these systems work together.
Answer: Nervous system, skeletal system, muscular system. The nervous system control the muscles and the skeletal system helps to support those muscles.
Explanation:
The nervous system consists of a set of cells specialized in conducting electrical and chemical signals, called neurons, and glial cells that are supportive. The nervous system picks up external stimuli from the environment or signals from the organism itself (internal stimuli), and this information is transmitted by nerves to the brain, where everything is processed and a signal is emitted that causes the contraction of certain muscles.
The nervous system is divided into central and peripheral systems. The central nervous system comprises the spinal cord and brain, while the peripheral nervous system comprises the nerves that connect the central nervous system to the body. Within the peripheral nervous system, there is a sensory (afferent) nervous system responsible for incorporating information from receptors (such as the eyes, the skin for touch, etc.), and a motor (efferent) system that carries the information to the muscles.
From the functional point of view, it is also differentiated into somatic and autonomic system. The somatic nervous system consists of neurons that control voluntary actions, while the autonomic nervous system is responsible for involuntary functions. And within the latter group are included the sympathetic nervous system (which is activated in situations of danger to stimulate many organ functions that cause a rapid response), the parasympathetic (which is involved in the regulation of several organs and its action is opposite to that of the sympathetic nervous system) and the enteric nervous system in the gastrointestinal tract.
The muscular system is a set of muscles that can be controlled voluntarily, if we refer to skeletal muscles. Their main function is mobility, an action that takes place when stimuli from the nervous system provoke the contraction of the muscle fibers. There are three types of muscle tissue: skeletal, smooth and cardiac, and all of them are able to contract but they differ in certain characteristics, location and the way in which the contraction is regulated, which can be voluntary or involuntary.
Muscle tissue receives electrical impulses from the nervous system and responds to them by generating a contraction movement. The neuromuscular junction plate is the connection established between a motor neuron and a muscle, by means of which the neuron transmits electrical impulses to the muscle fiber and between them there is a space called synaptic cleft. When a nerve impulse called action potential travels through the axon of a motor neuron, the neurotransmitter acetylcholine is released into the synaptic cleft, which binds to the muscle cell membrane and causes it to alter its membrane potential causing a depolarization that triggers contraction.
Finally, the skeletal system consists of a rigid structure formed by bones, and has several functions such as mechanical support, maintenance of posture, makes possible the bipedal position and protection of vital organs. The joints between two adjacent bones, called articulations, make muscular movements possible. In addition, the bones serve as insertion sites for the tendons of the muscles, which allow movement that is controlled by the nervous system and carried out mainly by the muscular system.
So, the nervous system control the muscles and the skeletal system helps to support those muscles.
