Answer: When a long-term environmental change occurs, certain individuals in a population will be better adapted for the new environment than others. These individuals will be more likely to survive and pass on their traits to their offspring. Over many generations, these favorable adaptations build up in a population. This may lead to specification, which is the development of a new species.

Conservationistis strive to preserve or improve biodiversity in ecosystems, which includes monitoring populations of organisms to detect changes. Name two challenges that scientists may encounter when they’re monitoring populations of organisms in the wild.
Answer:
Conservationists are responsible to preserve or improve the biodiversity in ecosystem. Many wildlife sanctuaries are made to protect the biodiversity. There are several ways by which conservationists accomplish their aim such as monitoring populations of organisms to detect changes and promoting importnce of wildlife.
Two main challenges conservationists will face while monitoring population of organisms in wild are:
weather conditions may not support the monitoring equipments or clothing.Wildlife animals are dangerous and can cause harm.Hence, conservationists face the above challenges while dealing with wild.
Answer:
One challenge is cost. To effectively monitor populations in the wild, scientists need special equipment such as cameras, computers, and GPS monitoring equipment. Another challenge is accuracy. It’s impossible to count every single organism in an ecosystem, so scientists often work with estimates.

Materials such as minerals, soil, fuels, and clean water are called
O natural resources
bio-elements
O habitats
O non of the above
Answer: natural resources
Explanation:
If, after adding those channels, you were to wait long enough for the system to equilibrate (i.e., reach a stable state in which the number and type of molecule in each compartment no longer changes much over time), about how many peptide molecules would you expect to find on the left side of the cell and how many on the right? How about the water molecules? Explain your reasoning.
Answer:
1 We can infer that when permeable channels are added to the peptides and a cell is incorporated in water, the concentration of peptides and water will change, generating an equilibrium causing an equivalence of equal intracellular and extracellular concentration
2. If there is no alteration and the environment is in equilibrium, we can say that there will be an equal concentration of petids and water in the intracellular and extracellular space. If we have 40 peptides on the left side, the right side will move looking for a balance and that both environments are the same, becoming 60 for each of the spaces
Although your question has some missing details a general answer is provided above
After adding the channels to a system to achieve equilibrium the number of peptide molecules on both sides of the cell have to be equal.
A difference in the peptide molecules on either side of the cell will lead to a diffusion gradient and this will lead to diffusion of peptide molecules from the side with higher concentration of peptide molecules to the side with lower concentration of peptide molecules ( this means that the system is not at a stable state ). while
A difference in the concentration of the water molecules will lead to an osmotic gradient ( this means the system is not at a stable state ).
Hence we can conclude that for the system to reach a stable state the number of peptide molecules and the water molecules on both sides of the cell should be equal.

You prepare an agar plate by spread plating & place an antibiotic disk in the middle of the plate. After incubating for a day at 37 degrees C, there are no bacteria on the plate. Which of the following is NOT a reasonable interpretation of what might have happened?
O The bacteria in the culture tube were already dead when you made the plate
O The medium used was defective and provided no nutrition for the bacteria
O The bacteria grew all over the plate but were then killed by the antibiotic
O The spreading tool was too hot when spreading the bacteria
Answer:
A.The bacteria in the culture tube were already dead when you made the plate
Explanation:
Antibiotics are the chemical substance used to kill or stop the growth of bacteria and some other microorganism.
Antibiotics are added to agar plate during experiment for the selection of only those bacteria with resistance to that antibiotic.
There can be several interpretation for the absence of bacteria such as:
The bacteria grows on the nutrients in the medium but due to defective medium they were unable to grow and die.It may also happen bacteria might have grown in all over the plate but due to the action of antibiotic, all the bacteria got killed.Tool used for spreading might kill bacteria as it was hot and bacteria may not be able to tolerate the excessive heat and die.Hence, the only not reasonable interpretation is bacteria in the culture tube were already dead when you made the plate.
So, the correct option is A.
Which of the following explains one of the ways plants and animals depend on each other?
A
Animals make minerals, which plants take in through their roots and pass up to their stems.
B
Animals release water vapor when they breathe, which plants take in through their leaves.
C
Animals make their own food, which plants take in through their roots and pass to their leaves.
D
Animals release carbon dioxide when they breathe, which plants take in to help make food.
Answer:
Animals release carbon dioxide when they breathe which plants take in to help make food
Animals release carbon dioxide when they breathe which plants take in to help make food. So the correct option is D.
Why do animals and plants depend on each other?
All species present on earth depend on each other for performing basic life processes. Humans are not able to survive beyond a particular range of temperature and pressure. For all the species to survive, a healthy environment is required.
Plants and animals are dependent on each other. This is because, in ecological systems, no species can survive alone. Animals are dependent on plants. Plants are the primary producers in our ecosystem. They produce food that is consumed by primary consumers and the primary consumers are consumed by secondary consumers.
Plants use carbon dioxide for photosynthesis and it results in the production of oxygen. This is used by animals for the process of respiration.
Plants depend on animals for several reasons. These can be fruit and seed dispersal, pollination, and also for the carbon dioxide that the animals produce. Thus, both plants and animals are interdependent on each other.
Therefore, the correct option is D.

Jaden’s mass is 50 kilograms. His weight on Earth is
Answer:
Weight of the Jaden on earth is 490 N.
Explanation:
Formula
w = mg
Where w is the weight of an object , m is the mass of an object and g is acceleration of gravity .
Gravity on Earth is 9.8 m/s² .
Jaden’s mass is 50 kilograms.
g = 9.8 m /s²
m = 50
Put the values in the formula
Thus
w = 50 × 9.8
= 490 kg m /s²
(As N = kg m/ s²)
= 490 N
Therefore the weight of the Jaden on earth is 490 N.

Based on Kepler's observations about planetary motion, what is the relationship between a planet's orbital velocity and its distance from the sun?
Answer is the greater the distance, the slower the orbital velocity..
I do not understand it. Can someone please explain it to me? Thank you!
Answer:
Explanation:
The closer the planet is to the sun,the faster it moves because the suns gravitational pull is stronger.The answer tells you that the greater the distance,the slower the planet will rotate
Kepler laws of planetary motion can be stated as planets move around the sun in elliptical orbits, the radi joins the planets to sun leaves out equal areas to equal intervals in the equal lengths of time.
The planets that are farther away from the sun have slow velocity and longer paths such as pluto. These factors make it longer for one complete revolution.Thus greater will be the distance the slower will be the velocity of movement such as that of mercury and pluto. As sun gravitational pull will be weaker.Learn more about the Kepler's observations about planetary motion.
