that accurately describe the shape of the graph as it relates to photosynthesis.
Rate of photosynthesis
Carbon dioxide
concentration
Carbon dioxide is not needed for the Calvin cycle, so the graph levels off after a certain point
The rate of photosynthesis increases as carbon dioxide levels increase.
In the photosynthesis graph, the rate of photosynthesis increases as carbon dioxide levels rise.
What is photosynthesis ?Photosynthesis is a process that plants and other organisms use to convert light energy into chemical energy that can then be released to fuel the organism's activities via cellular respiration. Photosynthesis is the process by which plants convert sunlight, water, and carbon dioxide into oxygen and sugar energy. Photosynthesis is the conversion of light energy by phototrophs into chemical energy, which is then used to power cellular activities. Sugars, which are formed from water and carbon dioxide, are used to store chemical energy. Photosynthesis occurs within the chloroplasts found in the mesophyll of the leaves.

because alcohol binds to neurons that normally receive the neurotransmitter gaba, it is not surprising that alcohol: a. is a stimulant. b. relaxes people. c. makes people feel sad. d. makes people throw up.
It is not surprising that alcohol relaxes people. Thus, the correct option for this question is B. This is because it binds to neurons that normally receive the neurotransmitter GABA.
What are Neurotransmitters?Neurotransmitters may be characterized as the types of chemical substances that are released by the transmission of nerve impulses through the synapse. These chemical substances are present within the synaptic cleft.
Under the influence of these chemical substances, the post-synaptic surface becomes depolarised resulting in a nerve impulse in the post-synaptic neuron. The same action is influenced by the alcohol that relaxes people through the liberation of neurotransmitters known as GABA.
Therefore, it is not surprising that alcohol relaxes people. Thus, the correct option for this question is B.

does The replication of DNA occur during anaphase?
To answer this question we need to remember a little of the cell cycle and the cell division process. When cell division starts (Prophase) the DNA condensates and forms chromosomes, at this point DNA, has to be already duplicated because when acquires a condensed form it can't be replicated or transcribed. Therefore replication occurs before, this is during the S phase (synthesis) of the cell cycle, previous to any phase of mitosis and meiosis.
Answer:
No, the replication of DNA does not occur during anaphase. DNA replication occurs during the synthetic phase (S phase) of the Interphase.
Prior to the industrial revolution, what was the previous highest level of co2 concentration in the atmosphere over the prior 400,000 years?.
For nearly 6,000 years of human civilisation, CO2 levels were continuously around 280 ppm before the Industrial Revolution.Since then, it is predicted that humans have produced 1.5 trillion tons of CO2 pollution, the most of which will keep the atmosphere heated for thousands of years.
What was the highest concentration of carbon dioxide in the last 400000 years before the Industrial Revolution?
We know that atmospheric carbon dioxide never went beyond 300 ppm during the ice age cycles of the past million years based on air bubbles trapped in mile-thick ice cores and other paleoclimate evidence.The atmospheric carbon dioxide level was at or below 280 ppm before the Industrial Revolution began in the middle of the eighteenth century.According to NOAA scientists, the amount of carbon dioxide in the atmosphere peaked for 2022 in May at 421 parts per million, pushing the atmosphere even further into regions unseen seen in millions of years. The Big Island of Hawaii's average carbon dioxide concentration, as measured by NOAA, was 420.99 parts per million (ppm), up 1.8 ppm from 2021.The independent record-keeping scientists at Scripps determined a monthly average of 420.78 ppmNOAA Administrator Rick Spinrad, Ph.D., stated that "the science is clear: humans are changing our climate in ways that our economy and our infrastructure must adapt to.""The effects of climate change are all around us and are evident every day.We need to take immediate, significant action to create a more climate-ready nation, as evidenced by the steady increase in carbon dioxide observed at Mauna Loa. Burning fossil fuels for electricity production and transportation, making cement, destroying forests, farming, and many other activities all contribute to CO2 pollution.The planet's atmosphere warms steadily as a result of the presence of CO2 and other greenhouse gases, which trap heat that would otherwise radiate from the surface and escape into space. This warming of the atmosphere triggers a variety of weather changes, such as periods of extreme heat, drought, and wildfire activity, as well as heavier precipitation, flooding, and tropical cyclone activity.Greater sea surface temperatures, rising sea levels, and increased carbon uptake are all effects of greenhouse gas pollution on the world's seas. These effects make sea water more acidic, promote ocean deoxygenation, and make it more challenging for some marine creatures to thrive. During the Cambrian period, around 500 million years ago, CO 2 concentrations in the atmosphere ranged from as high as 4,000 parts per million (ppm, on a molar basis) to as low as 180 ppm during the Quaternary glacial, which lasted for the past two million years.To learn more about carbon dioxide refer

(20 points)
Answer:
Horses
Humans
Mushrooms
Explanation:
Air, rocks, and water may have cells in them but they are not made of cells in and of themselves.
Bacteria is prokaryotic meaning it is a single cell so it is technically not "made of cells".
Horses, humans, and mushrooms are all made of cells.

The tendency to respond to a conditioned stimulus that is similar, but not identical, to the original conditioned stimulus is called _____.
The tendency to respond to a conditioned stimulus that is similar, but not identical, to the original conditioned stimulus is called discrimination.
A stimulus is a "detectable change (physical or chemical) in an organism's environment that induces some functional activity," according to the definition given . For instance, sunlight serves as a stimulus for plants and bodies, encouraging them to grow or move in its direction. High temperatures are another example of a stimulus since they cause our bodies to start sweating and cool down as a result.
Researchers who study human behaviour frequently use the phrase stimulus (or its plural stimuli). The activities, behaviours, or procedures that cause the human mind to react are known as stimuli in psychology. Visual, aural, physical, or a combination of these may be used as the stimuli. The use of stimuli in the management of achluophobia is one instance (fear of the dark).

In glycolysis, a glucose molecule is split into two molecules of ______, and energy is harvested as atp and nadh.
In glycolysis, a glucose molecule is split into two molecules of pyruvate and energy is harvested as ATP and NADH.
The process of glycolysis is the first stage of cellular respiration. Cellular respiration is the process through which glucose and oxygen react to produce energy in the form of ATP as well as NADH for the cells to function.
During the process of glycolysis, the glucose molecule is broken down. Energy is released by this breaking down of glucose. The glucose breaks into two pyruvate molecules.
The process of glycolysis occurs in the cytosol of a cell and it is a complex process with a series of steps.
