The diagram shows a reflex arc. Name parts P and Q shown on the diagram above.
Please help.
Answers
Answer:
P - synapse
Q - Relay neuron
Explanation:
A synapse, easy to remember as a neural junction, is the site where the transmission of electric impulses occurs. This occurs between two neurons or between a neuron and a gland or muscle cell. So in this scenario when we poke the finger it fires an electric nerve impulse that gets to the P spot that is a synapse and gets transmitted to the relay neuron. A relay neuron is there to receive the signal from one neuron and then transfer it to another interneuron resulting in the signal being received by a motor neuron so that we can react to the stimulus.

Consciousness can best be described as __(blank)__.
a) Internal chemical systems that are regulated by a circadian rhythm
b) an ability to sleep and have lucid dreams
c) a lack of awareness of things going on inside or outside of yourself
d) an awareness of things going on inside or outside of yourself
Answers
Consciousness can best be described as an awareness of things going on inside or outside of yourself, hence option D is correct.
How consciousness is regulated?Wakefulness/arousal and awareness are frequently used as the two components that make up consciousness.
It appears that proper arousal levels and subsequently wakefulness, which is required for consciousness, depend on well-synchronized phases of awake and sleep.
Circadian rhythms are changes in the body, brain, and behavior that occur on a 24-hour cycle. Most living things, including animals, plants, and bacteria, are impacted by these natural processes, which predominantly react to light and darkness.
Therefore, the 24-hour cycle of normal physical, emotional, and behavioral changes that the body experiences.

Explanation:
Lymph vessels pick up any fluid that has escaped the blood vessels and return it to the heart. Lymph nodes remove any foreign material from the lymph (bacteria, viruses, tumors) and contain lymphocytes (WBC!!!)
Each and every fluid that had already exited the blood arteries is collected by lymphatic vessels as well as returned towards the heart. Lymph nodules filter out foreign particles from either the lymph as well as house lymphocytes.

Answers
Answer:
3) CO2 + water
4) producers
5) oxygen
Explanation:
Autotrophs are producers which use sunlight, water and carbon dioxide to make their own food. This occurs via the process of photosynthesis in green plants, algae ,phytoplankton and cyanobacteria. These occupy essential places in the food web, and provide the energy used by hetertrophs or consumers.
6 CO2 + 6 H2O + light → C6H12O6 + 6 O2
Carbon Dioxide + Water + Light Glucose + Oxygen
Consumers carry out respiration to obtain the energy stored in carbohydrates produced by plants.
C6H12O6+ 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP
glucose+ oxygen → carbon dioxide+ water+ energy

Stand and let your hands hang next to your sides for a few minutes. Then, look at the backs of your hands. Do you see any bumps on the surface on top of your veins? What might those be, and what are their function?
Answers
When you stand and let your hands hang next to your sides for a few minutes, the bumps you see on your veins are the valves that help move blood to the larger veins.
What we know about vein valves.There are valves located throughout the veins in our bodies. Most of these are located in points where smaller venules fuse with the larger veins.
Their function is to prevent blood from flowing back into the smaller veins, thus helping with the normal blood flow of the body.
Given that the veins in our bodies are littered with small valves to help the blood return to the heart correctly, we can confirm that these are the small bumps that we can see when letting our hands down for a few mins, as they fill with the blood they try not to let flow back into the smaller veins.

Molecules that make up living things and contain carbon are called __________ molecules.
Answers
Molecules that make up living things and contain carbon are called organic molecules.
Organic molecules are those that derive their three-dimensional configurations primarily from their carbon skeletons.
Organic molecules are essential for the birth, development and functioning of all cells that make up living organisms.
About organic molecules:
All organic molecules contain carbon and practically always hydrogen, it is also frequent that they have oxygen or nitrogen.These chemical elements enable multiple and covalent bonds to be established, allow carbon atoms to develop three-dimensional skeletons, and give rise to multiple functional groups. Proteins, vitamins, carbohydrates, lipids, and nucleic acids are organic biomolecules, which are synthesized by living organisms.Therefore, we can conclude that molecules that make up living things and contain carbon are called organic molecules, which a living being needs to develop normally.

Nutrition is a common topic in the media, whether it's a new diet plan or a new "superfood" on the market to benefit
our health. Some of these products are scientifically sound, while others aren't. How do we tell the difference?
PLEASE HURRY
Answers
Answer:
To find out whether a product is scientifically sound, check the FDA standards for the product. Another option is to ask a medical expert, such as a doctor or a nutrition scientist, whether the product is scientifically sound.
As a scientist employed by the FDA, you've been asked to sit on a panel to evaluate a pharmaceutical company's application for approval of a new weight loss drug called Fat Away. The company has submitted a report summarizing the results of their animal and human testing. In the report, it was noted that Fat Away works by affecting the electron transport chain. It decreases the synthesis of ATP by making the mitochondrial membrane permeable to H+, which allows H+ to leak from the intermembrane space to the mitochondrial matrix. This effect leads to weight loss.How would you explain the decreased synthesis of ATP?
Answers
Answer:
The right response is "body temperature".
Explanation:
Whilst also growing the basal leakage of protons, this same drug Fat blocks the development of ATP. The whole change throughout the electrochemical gradient including its proton, therefore, induces the release of a possible form of radiation, rather than being transferred to ATP. Through thermoregulatory autophagy, outlet temperature throughout the individual contributes to loss, associated with elevated body temperature. Elevated body temperature would have the additional effect of removing fat.GUYS HELP FAST THE SAM ONE

so basically carrying capacity is "the amount of organisms a specific environment can support", so if the environment is increased, most likely, more space and food will be available, which means the environment can hold more organisms, causing the carrying capacity to increase
Explanation:
what I just said lol
Answer:
Increasing the habitat size will increase the carrying capacity. Carrying capacity is the maximum amount of organisms a habitat and its resources can carry. So if the habitat expands and more resources become available, the population would expand. As you can see for the first 15 years, when it was the little land, there was only about () rabbits, but as the land grew throughout the years, the rabbit population grew. 15-30 years with moderate land had around () rabbits, and the ample land in years 30-45 had around () rabbits, a little over two times the amount the little land had.

Running for a long period of time, such as during a marathon, can result in muscle fatigue. Which process is important to a runner at the end of a marathon?
A. lactic acid fermentation to produce ATP without oxygen
B. Alchoholic fermentation to release carbon dioxide
C. The Krebs cycle to produce NADH and FADH2
D. The electron transport chain to produce ATP
Answers
The process that is important to a runner at the end of a marathon is lactic acid fermentation to produce ATP without oxygen (Option A).
Cellular respiration refers to the reactions by which aerobic cells normally produce energy in the form of ATP by using energy stored in the chemical bonds of foods and oxygen.Muscle cells can produce ATP by both cellular respiration (aerobic conditions) and acid lactic fermentation (anaerobic conditions).Acid lactic fermentation is energetically much less efficient than cellular respiration, but ATP production in cellular respiration is much slower than in fermentation, thereby muscle cells use this pathway (fermentation) when they cannot get oxygen fast enough to meet their energy requirement.In conclusion, the process that is important to a runner at the end of a marathon is lactic acid fermentation to produce ATP without oxygen (Option A).
