Answer:
moving across both the plasma membrane and the outer membrane
Explanation:
Gram-negative bacteria are bacteria that have a plasma membrane, a thin peptidoglycan layer, and an outer membrane (the space between the plasma membrane and the outer membrane is known as periplasm). Moreover, Gram-positive bacteria exhibit neither outer membrane nor periplasmic space and are surrounded by thick layers of peptidoglycan. Gram-negative bacteria have developed different protein secretion systems (types I–VI and type VIII) in order to secrete proteins into the extracellular space. For such purpose, the XcpQ protein (which is an outer membrane protein from the secretin family) participates in different transport processes in Gram-negative bacteria.

Why is it that we use the two-name binomial nomenclature invented by Carl Linneaus still to this day?
A. Because mountain lions and pumas are actually very different animals.
B. Because the system is widely accepted and used all over the world universally.
C. Because everybody knows how to speak Latin and Greek.
D. Because Carl Linneaus was just that important.
Answer:
B. Because the system is widely accepted and used all over the world universally.
Explanation:
In contrast to earlier names that were made up of diagnostic phrases, binomial names (or “trivial” names, as Linnaeus himself called them) conferred no bias about the quality or value of plant species named. Rather, they served as labels by which a species could be universally addressed.
Answer:
B. Because the system is widely accepted and used all over the world universally.
Explanation:
We use the two-name binomial nomenclature invented by Carl Linneaus still to this day because, the system is widely accepted and used all over the world universally.

Earth scientists have concluded that the methods of harnessing energy that have been used over the past two centuries, such as the burning of fossil fuels, are causing climates around the world to change more quickly and suddenly than ever before in human history. Evidence includes increased air temperatures, rising sea levels, and the shrinking of glaciers in Greenland, Alaska, and other regions of Earth. The most complex level of organizational hierarchy that climate change could potentially affect is Earth’s
biosphere.

The most complex level of organizational hierarchy that climate change could potentially affect is Earth's biosphere.
What is biosphere?
The biosphere refers to the global ecological system that encompasses all living organisms and their interactions with the physical environment. It includes various interconnected ecosystems, such as forests, oceans, grasslands, and deserts, along with the diverse array of species and their habitats.
Climate change, with its wide-ranging impacts on temperature, precipitation patterns, and other environmental factors, can disrupt ecosystems and alter the distribution and abundance of species within the biosphere. These changes can have cascading effects on communities of organisms, populations of species, and the overall functioning of ecosystems. Therefore, the biosphere represents the highest level of organization that climate change can potentially impact.

Why did Gregor Mendel use peas in his experiments?
Peas grow very slowly.
Pea reproduction cannot be controlled.
Peas normally produce very few offspring.
Peas have characteristics that have two forms.
Answer: Peas have characteristics that have two forms
Explanation: He chose peas because they had been used for similar studies, are easy to grow and can be sown each year. Pea flowers contain both male and female parts, called stamen and stigma, and usually self-pollinate. Self-pollination happens before the flowers open, so progeny are produced from a single plant.
Peas having characteristics that have two forms is the reason they were
used by Gregor Mendel
Who was Gregor Mendel?He was a biologist and is regarded s the father of modern genetics. He
performed various experiments using pea plants.
The reason why the pea plants was used by him was as result of it having
characterisitics in two forms such as smooth and wrinkled etc.

1. Why should we care that the panthera tigris is going extinct? Explain how humans might be affected by the loss of the panthera tigris.
Answer: I believe tigers, also known as "Panthera tigris" are important to humans because they balance the ecosystem. When creatures go extinct they leave behind a scar that affects the ecosystem that is around them. Since Tigers are secondary consumers they control natural prey populations. The connection to the food web is very important and essential to keep this food web stable. Once something goes extinct it will cause the food web to shift and some primary producers will go out of control.
Explanation: Not sure if this helped at all this is just what I know about the food web. Panthera Tigris are secondry consumers so they control the primary producer population. This is just basic food web and ecosystem thinking. This is how they impact humans if they go extinct.

How does mining impact the enviorment
Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes.
Answer:
Mine exploration, construction, operation, and maintenance may result in land-use change, and may have associated negative impacts on environments, including deforestation, erosion, contamination and alteration of soil profiles, contamination of local streams and wetlands, and an increase in noise level, dust

If this helped you, I'd appreciate Brainliest! <3 TYwhere does osmosis take place
Answer:
In Gastrointestinal system:
When we eat food or drink water, it travels from our mouth, down our oesophagus and into our stomach. In the stomach, the food is broken into tiny pieces that are mixed with stomach liquids. This mush of food and stomach liquids is called chyme. The chyme travels into the small intestine. This is where osmosis takes place.
In our Kidneys:
Our kidneys keep blood and tissue fluid (internal environment) 'clean' by removing urea, excess water and other wastes and excreting them. This controls the amounts of dissolved substances in blood and tissue fluid, a process called osmoregulation. If tissue fluid becomes too concentrated, cells will lose water by osmosis and become dehydrated and if it becomes too dilute, cells will take in excess water by osmosis.

Answer: You Palpatine, I'd still have you.
Explanation:
The Pearson Correlation Coefficient is a tool used in understanding the behavior of gene expression. A positive ratio means a gene is induced in cancer cells and is transcribed at a higher rate. A negative ratio means a gene is suppressed in cancer cells or is transcribed less frequently than in normal cells. What form of gene expression do you think would lead to a correlation coefficient of one
Answer:
the gene is being expressed at an equal rate in both cell types
Explanation:
In statistics, the Pearson correlation is a linear measure of the association between two continuous variables. The Pearson's Correlation Coefficient may exhibit values between -1 and +1. A value equal to 1 shows a perfect correlation, indicating that when one variable increases the second variable also increases (when this value is +1) or decreases (when this value is -1). Moreover, when the Correlation Coefficient is equal to 0 it means that there is no correlation.
