What are tissues composed of?
Tissues are cells organized and associated, accomplishing different functions in the organism.
There are four types of tissues: epithelial, muscular, connective, and nervous.
All of them are composed of the same components that might vary according to the tissue and its functions.
CellsCells are the main component of tissues. Their shape, size, organization, and closeness vary from tissue to tissue.
Extracellular matrixThe extracellular matrix is the space between cells. It varies in size, state, and composition depending on the tissue.
It contains proteins, water, salts, and other macromolecules. This composition also varies.
Among their many different functions, we can mention hydration, mechanical pressure resistance, reproduction and cell differentiation, motility, substances diffusion, communication between cells, and damaged tissue repairing, among others.

Answer:

Explanation:
hope it is helpful
Answer:
Explanation:
: There's only one stable, long-lasting biosphere that we know of. It's the Earth. It shouldn't surprise you that human attempts to create sealed systems don't generally fare very well. The International Space Station, despite efforts to recycle everything possible (including converting urine to drinkable water--do you still want to be an astronaut?) to reduce costs, couldn't sustain life for long without a steady supply of provisions from, and garbage hauling back to, Earth. You know they try hard because, if all goes as planned, it costs about $10,000 to put a pound of payload (supplies) into Earth orbit. The BioSphere 2 project in Southern Arizona was an interesting and costly effort, but the original studies weren't very scientific and it proved quite difficult to keep just a handful of humans alive for a relatively short period of time. You can buy tiny sealed marine ecosystems enclosed in glass. They are beautiful curiosities, but the one I bought for my wife lasted less than a year before crashing. Among the crazier justifications for space exploration is that when (note the assumption of inevitability) we ruin the Earth, we will need new places to live (and, presumably, ruin). Unless or until we can do a lot better at building self-contained ecosystems, it would be a far better use of human effort to focus on preserving the only one we've got. Not only that but, if we make the Earth uninhabitable, I'm not sure we deserve to live somewhere else. But the challenge itself is interesting, and the scientific questions you can ask in the process of understanding, building, and trying to maintain such a system are valid. We're going to give it a try. Good luck! There's a Nobel Prize in it.
LeeAnn wants to organize her data from researching the effect of hours of sunlight on plant growth to see if there is a trend in the data. Which would be the best way for LeeAnn to display her data for analysis so she can make predictions about the amount of light needed for maximum growth?
in a line graph
in a data table
in a bar graph
in a pie graph
The best way for LeeAnn to display her data for analysis so she can make predictions about the amount of light needed for maximum growth will be a line graph.
When comparing how numerous items change over time in relation to one another or tracking smaller changes over longer periods of time, line graphs (also known as line charts) work well. The crucial term "over time" is your cue to think about creating a line graph for your data whenever you hear it. Because they are straightforward, simple to grasp, and efficient, line graphs are often used and effective charts. Hence LeeAnn can display her data using a line graph because plant growth is a small change and has to be recorded for a longer period of time.learn more about line graph here:

The common health-associated infection seen in an outpatient setting, called mrsa, is caused by which type of bacteria?.
Methicillin-resistant-staphylococcus-aureus (MRSA) infection is caused by the bacteria called staphylococcus aureus, which leads to skin infections in mild form and respiratory diseases in severe form.
Hospital-Acquired MRSA – is associated with infections that are caused due to exposure to hospital or nursing home environments.The infection can be caught through direct contact or contaminated hands. Sometimes touching used surgical instruments or infected bedsheets can also pass on the infection leading to severe pneumonia or blood infections. Hence, people hospitalized for longer durations, live in nursing homes, or visit hospitals regularly without protection are prone to get a staph infection.Hospital acquired MRSA often causes severe symptoms compared to community-acquired MRSA due to prolonged exposure to bacteria.learn more about MRSA here: https://brainly.com/question/8190489

How does water move from the biosphere to the atmosphere in the water cycle
Answer:
The water cycle depicts the ongoing circulation of water inside the Earth and atmosphere. It is a complicated structure with several functions. Water vapor evaporates from liquid water, compresses to create clouds, and falls back to earth as rain and snow.
Explanation:
The water cycle is a cyclical process in which water circulates between the earth's atmosphere, seas, and surface via precipitation, drainage in lakes and rivers, and return to the earth's atmosphere by absorption and evaporation. Throughout respiration, organisms exhale carbon dioxide and water vapor, which evaporates back into the atmosphere.

The water quality in the environment.
The air quality in the environment.
The air quality in the environment.
All of the above can affect photosynthesis.
Abiotic factors such as temperature, water quality, air quality, soil quality, and sunlight efficiency affect the rate of photosynthesis. Thus, the correct option is D, i.e. All of the above can affect photosynthesis.
What is Photosynthesis?Photosynthesis may be defined as a process through which green plants synthesized their own food (glucose) via carbon dioxide and water in the presence of sunlight.
The rate of photosynthesis primarily depends on the numerous abiotic factors which are present in a particular environment.
For example, Desert plants accomplish photosynthesis by the CAM pathway, which requires less water as compared to rainforest plants.
The maximum rate of photosynthesis occurs in the region of photosynthetically active radiation (PAR), which belongs to the wavelength of 400nm-700nm.

Question 5: How would you describe the effect of a 1°C increase of temperature on the biodiversity of the habitat in terms of number of populations and number of individuals in the populations? Use evidence from your graph and table to support your answer.
1°C increase of temperature can effect the biodiversity of the habitat in terms of number of populations and number of individuals in the population, it can either increase or decrease the population growth.
1°C increase in temperature on biodiversity can increase or decrease the population growth.
Population growth or change in number of individuals in the population of some organisms increases or decreases with the increase in temperature. The population of certain species such as Nassuar grouperand, Queen angelfish increases with the increase in temperature while some species such as sponges and algae decreased in population with the increases in temperature. This is because some species need high temperature to grow, so even a 1°C increase in temperature increases the population while some species need low temperature to grow, so high temperature kills them and population is decreased.

A population of mice thrive when grain and seed resources are plentiful. When food runs out, they compete with
one another for food and no longer produce offspring. This is an example of
O biotic potential
O group behavior
O individual behavior
O interspecific competition
individual behavior
Explanation:
if the mice are competing with each other that means that it's every man for himself.
The given example suggests the individual behavior of the mice because they change their behavior according to conditions.
How a population of mice affects the resources?In nature, organisms search for resources first, and if this availability is fulfilled, they reproduce themselves and increase the number of offsprings, but when the availability of resources are depleted they compete with each other.
The individual behavior of the mice in the population is defined as some mice fighting for the same resources and others mating with each other.
In the given question interspecific competition is not a right choice because it is the competition between the organism of two different species for the same resources.
