The carrying capacity of an ecosystem will most likely become unbalanced when?
Answer:
In a population at its carrying capacity, there are as many organisms of that species as the habitat can support. ... If resources are being used faster than they are being replenished, then the species has exceeded its carrying capacity. If this occurs, the population will then decrease in size.
Explanation:
When resources are depleted faster than they are replenished, the species has reached its carrying capacity. If this happens, the population will shrink in size.
What is carrying capacity?Carrying capacity is defined as the average population size of a species in a given habitat.
Environmental factors such as adequate food, shelter, water, and mates limit the species population size. If these requirements are not met, the population will decline until the resources recover.
Carrying capacity, or the maximum number of people that an environment can support over time without destroying or degrading it, is determined by three key factors: food availability, water availability, and space.
Carrying capacity is the maximum number, density, or biomass of people that a given area can sustainably support.
This is likely to change over time and is influenced by environmental factors, resources, and the presence of predators, disease agents, and competitors.
Thus, any disturbance in these factors can lead to an unbalanced carrying capacity.

You would need to combine the genes from 2 different populations. Since lowering the diversity of a population with cause there to be no variation. Which means that then the population cannot evolve in different ways such as to changing environmental factors and can face an extreme risk of extinction. I hope this helped!
When observing a specimen under medium power, which adjustment knob should be used to focus the image? Why?
Answer:
The coarse adjustment knob should only be used with the lowest power objective lens. Once it is in focus, you will only need to use the fine focus. Using the coarse focus with higher lenses may result in crashing the lens into the slide.
Explanation:
A tactic used long ago by conquering nations on those they sought to control was to
invade the land and salt the fields. What were they hoping to accomplish by doing
this?
Answer:
I don't know this answer sorry dear
Explanation:
hope other wilp help you soon
The invading nations aimed to devastate the agricultural productivity and food supply of the local population.
Salting the fields was a deliberate act of agricultural sabotage with long-lasting consequences. The process involved spreading large amounts of salt over the farmland, which effectively rendered the soil infertile, inhibiting the growth of crops and making it nearly impossible to cultivate food. This strategy was particularly effective in ancient times when agriculture was the primary means of subsistence.
The devastation caused by salting the fields not only impacted the present generation but also affected future generations as the soil remained barren and required significant efforts to be reclaimed for agricultural use. This tactic was not only meant to suppress immediate resistance but also to instill fear and discourage other potential adversaries from rebelling against the invading nation.

An astronaut leaves Earth's surface and begins orbiting Earth. How will his departure from Earth affect his mass and weight?
A:His mass and weight will remain constant.
B:His mass will increase; his weight will decrease.
C:His mass will decrease; his weight will increase.
D:His mass will remain constant; his weight will decrease.
His departure from Earth will affect his mass and weight by the mass
remaining constant and his weight decreasing.
Gravitational force is present on earth's surface and is responsible for
pulling bodies towards each other. It is also responsible for objects falling to
the ground thereby making them remain there.
Weight is calculated by mass multiplied with gravitational force. The
gravitational force on a body decreases with increase in altitude which is
why mass remains constant and his weight decreases.

Describe a situation in which being able to drink milk would give an individual an advantage with respect to survival and reproduction.
Answer/Explanation:
A family has a farm in which they grow crops and keep cows. During a particularly harsh winter, the crops failed to grow as well as they normally do. This means that their food supply was limited.
However, they also have cows, and cows produce milk. If this family were able to drink milk, they could get some nutrition from the milk. This means they are less likely to succumb to malnutrition and disease, and are more likely to survive and reproduce.

when the hypothalamus detects a temperature of 95F? Is this a negative or positive feedback?
Body temperature is regulated by negative feedback. The stimulus is when the body temperature exceeds 37 degrees Celsius, the sensors are the nerve cells with endings in the skin and brain, the control is the temperature regulatory center in the brain, and the effector is the sweat glands throughout the body.
1)What is a trophic level?
2) explain how energy travels through food web ? your response must include the following terms:
Decomposer,producer, primary, consumer , 10%.
3)why is energy reduced at successive trophic levels?
1. The trophic level is something's position in the food chain/food web.
2. Energy travels through out the food chain because all the animals eat each other and take each other's energy. The decomposers are eaten, the producers are eaten, but the primary consumers get all the energy.
3. The energy decreases because each animal decomposes the energy a little, before getting eaten. By the time the food reaches the top of the web, the energy is barely left.

All cells are physically and chemically similar.
Energy flow occurs within cells.
Answer: All living organisms are made up of one or many cells.

In 1830s, botanist Matthias Schleiden studied the tissues individually and proposed the cell theory for the first time. According to him all the living beings are made up of cells and cell is the basic unit of life.
As according to him in the cell division he was able to observe that the plants are made up of cells. This observation is indicating towards the fact that all living organisms are made up of one or many cells.

Geckos are a type of small lizard that live in tropical areas. Geckos are often eaten by birds, snakes and larger lizards so they need to blend into their surroundings. In one area, scientists had always found brown and green geckos that blended in with the grass and the leaves on the ground. Over time, though they found yellow geckos in the same population. Three students were talking about why there were yellow geckos. Ciena thought that the change came from a mutation in the population. Tibor thought the change came from the environment. Sasha though that Ciena and Tibor were both right. Who do you agree with and why do you think that?
Answer:
Not going to say this is right but, I think that Tibor is correct because if the land has changed more over time then the yellow ones have adapted to the new living conditions while the green one have found ways to live in that environment.
Energy can be measured in calories, 1,000 calories is called a kilocalorie (kcal),
If the producers have 10,000 kcal of energy and 10% is transferred to the primary
consumers, how much energy is transferred?
100 kcal
1,000 kcal
10 kcal
Plz help me which one is it!!!!!
Answer: 1,000kcal
10% of 10,000 is 1,000.
The amount of energy transferred if 10% is transferred to the primary consumers is 1000kcal
Given the following parameters
Amount of kcal the producer have = 10,000kCal
Percentage transferred to the primary consumers = 10% of the amount produced
Get the amount of energy transferred;
[tex]Energy \ transferred = \frac{10}{100} \times 10,000\\ Energy \ transferred =0.1 \times 10,000\\Energy \ transferred =\frac{10,000}{10}\\Energy \ transferred =1000kcal[/tex]
Hence the amount of energy transferred if 10% is transferred to the primary consumers is 1000kcal.
