describe what would happen to a deer population if all the wolves went extinct. what would happen to the deers main food source and other animals that rely on that food source?

Answers

Answer 1

You must go back to the 1930s, when the wolf population in Yellowstone was wiped out, to find the answer to that. Despite Yellowstone elk

Elk populations as a result did very well—possibly too well. Elk exceeded Yellowstone's carrying capacity and remained mostly stationary during the winter, relying primarily on young willow, aspen, and cottonwood plants for food. Beaver struggled because they depend on willows to survive the winter.

Yellowstone elk has healthier willow trees

This led to a situation that was paradoxical. The willow stands along streams were in poor condition in 1968, according to Smith, when the elk population was only about one-third of what it is today. Elk numbers have increased by three times, thus willow stands are strong now. Why? Elk don't have time to actively browse the willow because wolves' predatory pressure keeps them on the go.

the size of a certain insect population is given by p(t), where t is measured in days. at what time will the population equal ?

Answers

It will take approximately 16.05 days for the population to equal 600.

To find the time at which the insect population will equal 600, we can set up the equation P(t) = 600 and solve for t.

The given population equation is P(t) = \(100e^(0.1t).\)

Setting P(t) equal to 600, we have:

600 = \(100e^(0.1t).\)

To solve for t, we can divide both sides of the equation by 100:

6 = \(e^(0.1t).\)

To isolate the exponent, we can take the natural logarithm (ln) of both sides:

ln(6) = 0.1t.

Now, we can solve for t by dividing both sides by 0.1:

t = ln(6) / 0.1.

Using a calculator, we find that t is approximately 16.05 days.

Therefore, it will take approximately 16.05 days for the population to equal 600.

Gastrin, histamine, endorphins, serotonin, cholecystokinin, and somatostatin are hormones or paracrines that are released directly into the lamina propria. Which of the following cell types synthesize and secrete these products?
a) parietal cells
b) enteroendocrine cells
c) mucous neck cells
d) zymogenic cells

Answers

Answer:

The correct answer is option b, that is, enteroendocrine cells.

Explanation:

The specialized cells of the pancreas and the gastrointestinal tract exhibiting endocrine function are termed as enteroendocrine cells. These cells generate gastrointestinal peptides or hormones in response to a distinct kind of stimuli and discharge them into the bloodstream for the systemic effect. These are the most varied endocrine cells found within the body.  

The intestinal enteroendocrine cells produce somatostatin, cholecystokinin, motilin, enteroglucagon, and neurotensin hormones. The G cells present within the intestine produce gastrin. In the gastric glands, the gastric enteroendocrine cells are present, which produce histamine, and others like cholecystokinin, alpha and gamma-endorphin, somatostatin, and others.  

In the islets of Langerhans, the pancreatic enteroendocrine cells are present, which produce hormones like ghrelin, amylin, somatostatin, and pancreatic polypeptide.  

In the light-dependent reactions, where do you see examples of simple diffusion, facilitated diffusion, and active transport? Define the three types of transport briefly

Answers

In the light-dependent reactions of photosynthesis, we can see the examples of simple diffusion, facilitated diffusion, and active transport.

Simple diffusion: The diffusion of water and oxygen gas in and out of the thylakoid membranes and stroma.Facilitated diffusion: The movement of hydrogen ions (protons) from the thylakoid space to the stroma through the ATP synthase complex.Active transport: The active transport of hydrogen ions (protons) from the stroma to the thylakoid space against the concentration gradient, which is powered by the energy stored in ATP.

Brief definitions of the three types of transport:

Simple diffusion: Movement of molecules from an area of high concentration to an area of low concentration until a balance is reached.Facilitated diffusion: Movement of molecules from an area of high concentration to an area of low concentration with the help of a carrier protein.Active transport: Movement of molecules from an area of low concentration to an area of high concentration, powered by energy from metabolic processes such as ATP hydrolysis.

the connection between limiting factors and invasive species

Answers

Answer:

Biology, Ecology, Earth Science, Climatology, Geography

Explanation:

A limiting factor is anything that constrains a population's size and slows or stops it from growing. Some examples of limiting factors are biotic, like food, mates, and competition with other organisms for resources. Others are abiotic, like space, temperature, altitude, and amount of sunlight available in an environment. Limiting factors are usually expressed as a lack of a particular resource. For example, if there are not enough prey animals in a forest to feed a large population of predators, then food becomes a limiting factor. Likewise, if there is not enough space in a pond for a large number of fish, then space becomes a limiting factor. There can be many different limiting factors at work in a single habitat, and the same limiting factors can affect the populations of both plant and animal species. Ultimately, limiting factors determine a habitat's carrying capacity, which is the maximum size of the population it can support

What hormones are released by the ovaries?

Answers

The ovaries release a number of hormones, including estrogen, progesterone, and testosterone. These hormones play important roles in regulating the menstrual cycle, preparing the body for pregnancy, and maintaining overall reproductive health.

The ovaries are two tiny, oval-shaped glands that are situated on either side of the uterus. They create and store your eggs (also known as ovum), as well as the hormones that regulate both pregnancy and your menstrual cycle. One of your ovaries releases an egg during ovulation. You can get pregnant if this egg is fertilized by a sperm. Until you reach menopause, your ovaries will continue to release an egg every menstrual cycle. The fallopian tube, a short, hollow structure, is where the egg starts its journey to the uterus. The amount of progesterone increases as the egg passes through the fallopian tube, aiding in preparing the uterine lining for pregnancy. Estrogen and progesterone are secreted by your ovaries. These hormones are crucial for menstruation and reproductive development. Prior to ovulation, during the first half of your menstrual cycle, estrogen production is at its peak. The second half of your cycle sees an increase in progesterone to prime your uterus for a fertilized egg.

How does a cold ocean current affect the climate along the coast?

A. Cold ocean currents do not affect the climate of the coast; only warm currents affect climate. B. The cold ocean current results in a cooler coastal climate. C. The cold ocean current results in a warmer coastal climate. D. The cold ocean current results in a drier coastal climate

Answers

A colder coastal climate is a result of the cold ocean current.

The climate of coastal locations can be influenced by warm and cold ocean currents, but only when local breezes come in from the sea. Warm currents raise the temperature over land by warming the air above the ocean. Cooler air can be brought across land by cold currents, which can also reduce air temperatures.

In order to balance out the unequal distribution of solar energy reaching Earth's surface, ocean currents govern the global climate. Regional temperatures would be more severe without ocean currents, with extremely hot temperatures near the equator and icy temperatures at the poles, and considerably less of Earth's land would be livable.

Which organism/s from the food web is/ are decomposers? How are they important to us?

Answers

The decomposers in the food web are organisms like fungi and bacteria that break down dead organic matter and return nutrients to the soil. They are important because they help in the decomposition process, which is essential in nutrient cycling and soil formation, and they play an important role in the food web by breaking down dead organic matter into simpler compounds that can be reused by other organisms.

Here is an example of a food web that includes decomposers:

Grass → Grasshopper → Rat → Snake → Hawk

In this food web, the decomposers would be organisms like fungi and bacteria that break down the dead bodies of the grasshopper, rat, snake, and hawk and recycle the nutrients back into the soil. Without decomposers, dead organic matter would accumulate and nutrients would be locked up in dead bodies, making them unavailable to other organisms in the food web. This would have a detrimental effect on the ecosystem as a whole.

Minerals can be classified based on cleavage or fracture. These two properties refer to the way in which a mineral tends to break. Cleavage is an orderly breakage in well-defined planes. It means that the broken piece of mineral will have flat and smooth sides. Fracture is a random breakage. If a mineral breaks with rough, random, uneven surfaces, it is said to have fractured. Because each of your mineral samples have already been broken from another, larger piece of a mineral, you should be able to tell if it has cleavage or fractures by looking at its sides. Of your 10 minerals, identify three that experienced cleavage. a cube-shaped gray mineral with smooth faces and sharp edges,a rust-colored mineral with a rough, uneven surface

Answers

The cube-shaped gray mineral with smooth faces and sharp edges likely experienced cleavage.

Cleavage is characterized by orderly breakage in well-defined planes, resulting in flat and smooth sides on the broken piece of a mineral. The cube-shaped gray mineral described with smooth faces and sharp edges fits this description. The smooth faces and sharp edges suggest that the mineral broke along specific planes, indicating cleavage.

On the other hand, the rust-colored mineral with a rough, uneven surface is more likely to have experienced fracture. Fracture refers to random breakage, resulting in rough, random, and uneven surfaces on the broken piece of a mineral.

It's important to note that visual inspection alone may not always provide definitive information about the cleavage or fracture of a mineral.
