is notable among neurotransmitters in that it seems to produce only ______________ post synaptic potentials.
Answers
GABA (Gamma-aminobutyric acid) is notable among neurotransmitters in that it seems to produce only inhibitory post-synaptic potentials.
A neurotransmitter is a chemical substance that is released by a neuron to carry information to another cell or neuron across a synapse. In this context, post-synaptic potentials (PSPs) are electrical signals that are generated in the dendrites of neurons. PSPs are caused by the influx or efflux of ions across the membrane of a neuron.
Inhibitory post-synaptic potentials (IPSPs) are one type of PSP. IPSPs cause the inside of a neuron to become more negative, making it less likely to generate an action potential and release neurotransmitters. GABA is the primary inhibitory neurotransmitter in the mammalian nervous system and plays an important role in regulating neuronal excitability in various regions of the brain.

Compared to worms, insects are highly responsive to environmental stimuli. Identify 2 external nervous system adaptations shown that make this possible in the insect?
Answers
Answer:
Eyes, Antenna and Hairs on their cuticle
Note: There are no diagrams or attachments provided.
Explanation:
Eyes
The eyes of insects serve the function of vision. Insects eyes are of two kinds; simple eyes or ocelli, and compound eyes. The simple eyes or ocelli can sense only light, darkness, and movement. The compound eye which consists of individual light receptive units called ommatidia can distinguish brightness and colour. More ommatidia in an insect's compound eye results in more clarity of vision
Hairs
Tiny hairs known as setae found all over the cuticle of insects are sensitive to vibration touch and sound and therefore serve as sense organs of touch and sound for insects.
Antenna
The antenna in insects serves various sensory functions such as sensing touch, air motion, heat, vibration (sound), and especially smell or taste.
Where is the surface water saltiest, near the coast or in the middle of the ocean? Many students expect the water to be fresher (less salty) at this location. Why? What typically makes this part of the ocean fresher? Why is the water at this location along the coast of California (sometimes) unusually salty?
Answers
Surface water is typically saltiest near the coast rather than in the middle of the ocean.
Why is the surface water saltiest near the coast?The salinity of surface water is influenced by various factors, including evaporation, precipitation, and freshwater input from rivers. Near the coast, there is often a higher concentration of salts due to limited freshwater input and high evaporation rates. Evaporation causes water molecules to escape, leaving behind the dissolved salts, thus increasing the salinity. Additionally, coastal areas may experience higher levels of evaporation due to warmer temperatures and stronger sunlight. This combination of factors leads to a higher salinity near the coast compared to the middle of the ocean.
However, it is important to note that salinity levels can vary depending on specific coastal characteristics and regional factors. For example, along the coast of California, the water can sometimes be unusually salty due to specific oceanographic conditions. These conditions may include upwelling events, where cold, nutrient-rich waters from the deep ocean rise to the surface. These upwelling events can bring in water with higher salinity, resulting in temporary increases in coastal salinity levels.
Understanding the factors influencing coastal salinity is crucial for various reasons, including ecosystem health, water management, and the impacts of climate change. By studying and monitoring salinity patterns, scientists can gain insights into ocean circulation, climate dynamics, and the distribution of marine organisms.

A bag contains 3 red marbles, 6 blue marbles and 4 green marbles. If three marbles are drawn out of the bag, what is the probability, to the nearest 1000th, that all three marbles drawn will be blue?
Answers
The probability, to the nearest 1000th, of drawing all three blue marbles from the bag is 6.2%.
To calculate the probability of drawing all three blue marbles, we need to consider the total number of marbles in the bag and the number of blue marbles available for selection.
The total number of marbles in the bag is 3 (red) + 6 (blue) + 4 (green) = 13 marbles.
The probability of drawing the first blue marble is 6 blue marbles out of 13 total marbles, so the probability is 6/13.
After drawing the first blue marble, there are 5 blue marbles left out of the remaining 12 marbles. Thus, the probability of drawing the second blue marble is 5/12.
Similarly, after drawing the first and second blue marbles, there are 4 blue marbles left out of the remaining 11 marbles. Therefore, the probability of drawing the third blue marble is 4/11.
To find the probability of all three events occurring together (i.e., drawing three blue marbles in succession), we multiply the individual probabilities:
P(3 blue marbles) = (6/13) * (5/12) * (4/11) ≈ 0.062 (rounded to the nearest 1000th)
Therefore, the probability, to the nearest 1000th, of drawing all three blue marbles from the bag is approximately 0.062 or 6.2%.

do plants require light? how can you tell?
do plants require carbon dioxide? how can you tell?
do plants require chlorophyll? how can you tell?
Answers
Answer:
Yes, plants require light to carry out the process of photosynthesis, which is the process by which they convert light energy into chemical energy in the form of glucose. Plants use glucose as a source of energy to carry out their life processes.
We can tell that plants require light by observing their growth and development in the presence and absence of light. In the absence of light, plants grow slowly, become pale or yellowish, and may eventually die. On the other hand, in the presence of light, plants grow vigorously, develop green color due to the presence of chlorophyll, and produce flowers, fruits, and seeds.
Yes, plants require carbon dioxide to carry out the process of photosynthesis. During photosynthesis, plants take in carbon dioxide from the atmosphere and use it to synthesize glucose.
We can tell that plants require carbon dioxide by observing their growth and development in the presence and absence of carbon dioxide. In the absence of carbon dioxide, plants grow slowly and may eventually die. On the other hand, in the presence of carbon dioxide, plants grow vigorously and produce more biomass.
Most plants require chlorophyll to carry out the process of photosynthesis. Chlorophyll is a green pigment found in the chloroplasts of plant cells that absorbs light energy and converts it into chemical energy.
We can tell that plants require chlorophyll by observing the color of the plant. Plants that have chlorophyll appear green in color, while plants that lack chlorophyll, such as some parasitic or saprophytic plants, appear yellow or white. Additionally, plants that lack chlorophyll are not capable of carrying out photosynthesis and must obtain their nutrients from other sources.
___ cross-fertilized pea plants that breed true for different forms of a trait, and discovered that the traits of the offspring often appear in ____ patterns.
Answers
Gregor Mendel cross-fertilized pea plants that breed true for different forms of a trait and discovered that the traits of the offspring often appear in predictable patterns.
Gregor Mendel conducted his experiments by selectively breeding pea plants that exhibited contrasting traits such as tall vs. short, smooth vs. wrinkled seeds, yellow vs. green seeds, etc. He then observed the offspring of these crosses and recorded their traits. Through his experiments, Mendel developed the principles of heredity and established the laws of inheritance.
His experiments revealed that the inheritance of traits is determined by genes that are passed down from parents to offspring in a predictable manner. The patterns of inheritance that Mendel observed included dominant and recessive traits, segregation of alleles during gamete formation, and independent assortment of genes.
Mendel's work laid the foundation for modern genetics and his principles are still studied and used today to understand genetic disorders and improve crop production.

The biggest harm to human health from arsenic comes from contaminated water used for drinking, food preparation, and irrigation of food crops.
It cause cancer and skin sores when consumed over an extended period of time. Diabetes and cardiovascular disease have also been linked to it. Exposure during pregnancy and in the early years of life has been associated to impaired cognitive development and an increase in the mortality of young adults.The most crucial measure in the affected communities is to provide a safe water supply in order to stop future arsenic exposure.Replace supplies with high levels of arsenic, such as groundwater, with sources with low levels that are also safe for microorganisms, like rainwater and treated surface water.Install centralized or household methods for removing arsenic, and make sure the extracted arsenic is disposed of properly. Technologies for removing arsenic include membrane processes, oxidation, coagulation-precipitation, absorption, and ion exchange. The key to successful interventions is community involvement and education. Avoiding drinking arsenic-contaminated water is the greatest strategy to prevent arsenic poisoning. Instead of attempting to remove arsenic from water for community water supplies, it would be feasible and more cost-effective to transfer to a source of water that is lower in arsenic.Learn more about Arsenic here:

explain how meiosis results in the transmission of chromosomes from one generation to the next (ist-1.f).
Answers
Meiosis is a specialized cell division process that allows the transmission of chromosomes from one generation to the next. During meiosis, a parent cell divides into four daughter cells that contain half the number of chromosomes as the parent cell.
Meiosis includes two stages of cell division: meiosis I and meiosis II.In meiosis I, the process of recombination occurs. Recombination occurs when homologous chromosomes cross over one another and exchange genetic information. The end result is that each chromosome becomes a unique combination of maternal and paternal genetic material. During metaphase I, the homologous chromosomes align on the equator of the cell and then separate from one another. Each daughter cell contains a single set of chromosomes.In meiosis II, the daughter cells from meiosis I divide again to produce four haploid gametes. The haploid gametes can then combine during fertilization to form a diploid zygote that contains a complete set of chromosomes. In this way, meiosis enables the transmission of chromosomes from one generation to the next. The transmission of chromosomes from one generation to the next is possible due to the process of meiosis.
