why was it impossible to know about bacteria 5,000
years ago
Answer:
Im assuming because microscopes hadnt been invented. Also the idea of communicable diseases wasnt around so people assumed it was things like god that caused illness
Answer:
A true understanding of the physiology of these bacteria and their roles in ecology, host health, and natural product production requires their cultivation in the laboratory. Recent advances in growing these species include coculture with other bacteria, recreating the environment in the laboratory, and combining these approaches with microcultivation technology to increase throughput and access rare species. These studies are unraveling the molecular mechanisms of unculturability and are identifying growth factors that promote the growth of previously unculturable organisms. This minireview summarizes the recent discoveries in this area and discusses the potential future of the field.

Messages are carried from the eyes to the brain by Question 5 options: nerves muscle light blood vessels.
Answer: Messages are carried from the eyes to the brain by nerves.
(specifically optic nerves)
Explanation:
When we see something, our eyes send messages to our brain through the optic nerves. Each nerve contains around a million long 'wires', called axons, which carry information from ganglion cells in the retina to relevant parts of the brain.
I got it from Goog|e, I hope it helps.
Messages are carried from the eyes to the brain by NERVES. These fibers send sensory messages between the body and brain.
The nerves are groups of fibers that receive and send sensory messages between the body and brain.
The cells that form nerves are called neurons, which use electrical and/or chemical (neurotransmitter) signals to transmit sensory information.
The optic nerve is a specialized nerve that transmits different types of visual sensory information (i.e., brightness, color, perception, contrast, etc).

First image shows a stationary organism whereas the second image indicates predator.
The first picture represents a leaf structure which is a part of plant and we know that plant is a stationary organism means it can't move from one place to another so that's why it is called a stationary organism.
While on the other hand, the second picture represents predator due to the presence of sharp teeth which helps the predators in catching and tearing of prey so we can conclude that first image shows a stationary organism whereas the second image indicates predator.

Explain the importance of scientific names.
Answer:
Every recognized species on earth (at least in theory) is given a two-part scientific name. This system is called "binomial nomenclature." These names are important because they allow people throughout the world to communicate unambiguously about animal species.
Researchers continued to record the deer population for many years after the coyote reduction. After a few years of growth, the deer population stopped changing much and stayed consistent. What is the term that best describes the continued stability of the population in this ecosystem?
Exponential growth
Carrying capacity
Overshoot
Limiting factor
Carrying capacity is a constant that equals population size at the equilibrium point. The term that best describes the continued stability of the population is option B, carrying capacity.
---------------------------------
Populations that exhibit the logistic growth model depend on density.
Natality and mortality depend on the population size, meaning that there is no independence between population growth and population density.
When a population grows in a limited space, density rises gradually and eventually affects the multiplication rate.
The population per capita growth rate decreases as population size increases.
The population reaches a maximum point delimited by available resources, such as food or space. This point is known as the carrying capacity, K.
K is a constant that equals population size at the equilibrium point, in which the natality and the mortality rate get equal to each other.
Assuming that population size is N, when
N<K, the population can still grow. N approximates to K, the population´s growth speed decreases. N=K the population reaches equilibrium, N>K, the population must decrease in size because there are not enough resources to maintain that size.The sigmoid curve represents the logistic growth model.
The carrying capacity might be affected by different factors, known as limiting factors, which might be a result of the population density (for example, competition) or might be density-independent.
Dense-independent factors might be human impact or natural disasters (fires, volcanic eruption, flooding).
In the exposed example we have a small population of deer that could grow and increase in size because of the absence of its predator.
This deer population exhibited continuous growth until it reached a certain point in which it remained stable.
This point is the carrying capacity.
At this point N = K ⇒ the deer population stoped increasing its size because it reached the environmental maximal capacity.

the enzyme dicer chops dsrna molecules into small pieces of
The enzyme dicer chops dsRNA molecules into small pieces of miRNA and siRNA. The correct option is B.
What is Dicer?
Dicer is an enzyme involved in RNA interference (RNAi), a cellular process that regulates gene expression.
Its primary role is to cleave double-stranded RNA (dsRNA) molecules into smaller fragments.
These fragments are typically around 21-25 nucleotides in length and serve as the building blocks for two types of small RNA molecules: microRNA (miRNA) and small interfering RNA (siRNA).
miRNAs are endogenous small RNA molecules that play a crucial role in post-transcriptional gene regulation. siRNAs are also small RNA molecules but are primarily involved in the defense against viral infections and the silencing of transposable elements.Thus, the correct option is B.

Hormones exert an effect only on a gland or organ that has a ________ where that specific hormone can bind.
Hormones excite, inhibit, or regulate the activity of other organs when they exert their effect on a target cell where that specific hormone can bind.
A hormone is the substance secreted by certain glands that promotes, blocks or regulates the activity of the organs.
Target cells are cells that possess specific receptors for hormones on their surface.The recognition of a hormone by its target cell lies in the presence at the cellular level of glycoproteins, called receptors, which bind specifically to the hormone, with high affinity and in a reversible way.Receptors present some differences related to the type of hormone or neurotransmitter to which they bind, with their location in the cell and with the way of transferring information after their union with these molecules.Therefore, we can conclude that hormones are produced by certain glands, circulate through the blood and reach other cells called target cells, exerting a regulatory effect on them.

What does an alcoholic beverage contain that is a central nervous system depressant? 
Answer:
interferes with release of neural transmitter GABA
Explanation:
Alcohol is a central nervous system depressant, meaning it slows down brain functioning and neural activity. Alcohol does this by enhancing the effects of the neural transmitter GABA
depressants essentially "look" like the neural transmitter and so they go in and block the plasce in the brain between synapses, so when the body tries to release GABA, it appears as if it is already filled in, but in reality it is the alcohol that has filled it. once they start buidling up, they block enough that it impairs brain activity
Answer:
GABA
Explanation:
gamma-aminobutyric acid (GABA)

An inventor claims to have invented an artificial kidney for patients that need a kidney
transplant. Which of the following would be a reason that the scientific community might
reject this claim?
A. Previous investigations were unable to obtain the same results.
B. The inventor failed to present observations with data.
C. Investigations were performed in an unknown laboratory.
D. The device failed to follow law of conservation of mass
All of the given options could potentially be reasons why the scientific community might reject the inventor's claim, but the option that specifically relates to the principles of science is option D: the device failed to follow the law of conservation of mass.
What is an artificial kidney?In the case of an artificial kidney, the device is supposed to filter out waste products from the blood, which is then supposed to be removed from the system in a measurable form, such as through urine or dialysis fluid. If the device fails to remove the waste products from the blood, or if it makes them disappear without a measurable output, it would suggest that the device is not functioning as claimed and may not be effective in treating patients who need a kidney transplant. Therefore, the scientific community would likely reject the inventor's claim until there is evidence that the device follows the fundamental principles of science, such as the law of conservation of mass
Hence, the option that specifically relates to the principles of science is option D: the device failed to follow the law of conservation of mass.

Describe the path of a phosphorous atom through four parts of the phosphorous cycle. Be sure to explain the processes involved in the transfers. Note when a form of phosphorous is available to plants. (Will mark brainliest)
Answer: One of the ways the path of a phosphorous atom starts is in a rock containing phosphate. The rock weathers, so that a phosphate ion enters the soil. A plant takes up the phosphate ion and incorporates it into a DNA molecule in a pollen grain. The grain falls back to the ground and decomposes, converting the atom back into phosphate through mineralization. The phosphate ion then leaches into the groundwater, leaving the soil.
Explanation: Plato/ Edmentum
Phosphorus moves in a cycle through rocks, water, soil and sediments, and organisms. Over time, rain and weathering cause rocks to release phosphate ions and other minerals.
This inorganic phosphate is then distributed in soils and water. Plants take up inorganic phosphate from the soil.
How does phosphorus enter the phosphorus cycle?
Phosphorus enters the atmosphere from volcanic aerosols. As this aerosol precipitates on earth, it enters terrestrial food webs. Some of the phosphorus from terrestrial food webs dissolves in streams and lakes, and the remainder enters the soil. Another source of phosphorus is fertilizers.
