Why is it important for your brain to control many functions automatically?
Answer:
The brain controls what you think and feel, how you learn and remember, and the way you move and talk. But it also controls things you're less aware of — like the beating of your heart and the digestion of your food.
Think of the brain as a central computer that controls all the body's functions. The rest of the nervous system is like a network that relays messages back and forth from the brain to different parts of the body. It does this via the spinal cord, which runs from the brain down through the back. It contains threadlike nerves that branch out to every organ and body part.
Explanation:
If you brain does not, or is unable to perform multiple tasks automatically, you could have trouble breathing on your own, your heart could have problems, even your thought process, movement, and digestion could malfunction. Which could cause a multitude of complications.

2.) State the relationship between photosynthesis and cellular respiration.
Answer:
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

Marine biologists are studying stickleback fish populations. There are two distinct variations in the sticklebacks based on phenotypes. They are found with the three spines more commonly in marine ecosystems while they are more commonly found without the three spines in freshwater ecosystems. This has been observed in many marine and freshwater ecosystems across the globe. What explains the variation seen in the image here across different aquatic ecosystems?
Answer:
Presence of predators.
Explanation:
Presence and absence of predators is the main cause of the presence of spines on stickleback fish populations because these spines helps in the protection against predators. The stickleback fish populations that lives in marine ecosystem have spines because there are many predators are present while on the other hand, stickleback fish populations of freshwater ecosystems have no spines due to no predator so they acquire the adaptation of having no spines.
In this exercise we have to explain the variations of the aquatic system, so we have to:
In this case, as long as a large increase in a specific population of fish takes place, we know that the predators of this system are needed.
What factors interfere in an ecosystem?They are:
Biotic factors: producing beings (plants and algae), consuming beings (herbivores and carnivores) and decomposing beings (fungi and bacteria). Abiotic factors: water, light (light energy), heat (thermal energy) and nutrients (chemical substances).See more about ecosystem at brainly.com/question/1673533

An organism has control over inherited traits.
la cromatina esta formada por adn asociado a
Answer:
La cromatina es una sustancia dentro de un cromosoma que consiste en ADN y proteínas. El ADN lleva las instrucciones genéticas de la célula. Las principales proteínas de la cromatina son las histonas, que ayudan a empaquetar el ADN de una forma compacta que cabe en el núcleo celular. Los cambios en la estructura de la cromatina se asocian con la replicación del ADN y la expresión génica.
Explanation:
(b) Identify the dependent variable in the experiments. Identify a control group missing from the second experiment. Justify the need for this control group in the second experiment.
Hello. You have not submitted the experiments to which this question refers, which makes it impossible for it to be answered. However, I will try to help you in the best possible way.
A dependent variable is one that is influenced by an element, in order to present a result, that is, it is a variable that does not establish itself, being dependent on another variable to establish itself. An example of a dependent variable can be seen in an experiment that seeks to determine the differences in growth rates of bean plants that were fertilized with different organic fertilizers. As you can see, this is an experiment where the different organic fertilizers influence differences in the growth rate of bean plants. Thus, the growth of these plants depends on the fertilizer, this growth being the variable dependent on the experiment.
A control group, in turn, is an element of the experiment that does not receive the element that is being tested in the same experiment. The control group is important, because it allows the researcher to see the results of a system where the tested element does not exist, thus being able to determine the real differences that the tested element is capable of causing. Using the same example presented in the paragraph above, we can see that the different organic fertilizers are the elements tested in the experiment. These fertilizers will be applied to the plants, however it is important that at least one of these plants does not receive any fertilizer, so that the difference between a system with fertilizer and a system without fertilizer can be evaluated. This plant that received no fertilizer is the control group.
positive impacts humans have on water
Answer:
Positive Human Interaction When people build dams channeling off large bodies of water, the water builds up along the edge of the lake, pond, or stream creating very fertile soil from the constant watering and these areas on the outside of lakes and ponds are used by humans for growing and farming crops.

What is fracking fluids?In order to enhance the amount of hydrocarbons that may be extracted, drilling operations use fracking fluid (also known as frac fluid). The fluid stops the well from corroding. Among other things, it prevents blockages, bacteria from growing, and lubricates the extraction process.
In summary, the chemical composition varies from well to well and is complicated. Depending on the exposure amount, several of these substances can be dangerous to human health.
According to estimates from the oil and gas sector, chemical additives only make up about 1%.
Therefore, It destroys animal habitats and causes topsoil to erode- deforestation 2) pollutes groundwater with dangerous chemicals- injecting fracking fluids into the ground 3) harms aquatic creatures and vegetation- oil spills during transport on a ship.

7. (True Story) In Denmark, a husband and wife who had been unsuccessfully trying to have a
baby went to a fertility clinic. Sperm and eggs were collected from father and mother, and
combined in a petri dish, creating several "test-tube babies". These babies were implanted in the
mother and 9 months later she ſlelivered twins, one with lightly pigmented skin and one with
darkly pigmented skin. Because this seemed strange, a DNA test was conducted and it was
found that both children were related to the mother, but only the light skinned child was related to
the father. How can this be explained? (Hint, there was no infidelity)
Answer:a
a possible explanation for this occurrence is that a test tube or dropper was accidentally used repeatedly without being sterilized, causing sample cross-contamination. DNA in this test case did not confirm that the father of the second child was another client of the fertility clinic who had never met the mother...therefore this is a possibility.

Explanation:
What is the role of complementary base pairing in the replication of DNA?
A It reduces the number of errors in the process of DNA replication.
B It introduces more hydrogen bonds between the nucleotides.
C It ensures that the replicated DNA is an exact copy of the parent DNA.
D It allows the replicated DNA to have a different nucleotide arrangement
Answer:
c. it ensures that the replicated DNA is an exact copy of the parent DNA
Explanation:
This means that each of the two strands in double-stranded DNA acts as a template to produce two new strands. Replication relies on complementary base pairing, that is the principle explained by Chargaff's rules: adenine (A) always bonds with thymine (T) and cytosine (C) always bonds with guanine (G).
