A density-dependent factor is one where the effect of the factor on the size of the population depends upon the original density or size of the population. A disease is a good example of a density-dependent factor. If a population is dense and the individuals live close together, then each individual will have a higher probability of catching the disease than if the individuals had been living farther apart. Not only will a greater number of individuals be affected, but, more importantly, a greater proportion of the population will be affected if they are living close together. For example, bird populations are often regulated more by this type of regulation.

Excretion is the process of removing metabolic waste products from the body, such as urea through the kidneys. Egestion, on the other hand, is the removal of undigested food materials from the digestive tract, typically in the form of feces.

Groundwater is another name for subterranean water held in cracks and pore spaces of the earth.

Barbara spent years of research and after a very careful study of many generation. In 1944 McClintock recognized Jumping of DNA, which refer to unstable of DNA to move around between the chromosomes. But for many years her theory was disregarded.

In 1983, the theory of jumping DNA or which is known today "Transposable" was confirmed. In 1983 McClintock was awarded The Nobel Prize in Genetics for the discovery of genetic transposition.

Histones are the main proteins associated with DNA in the cell, forming chromatin structure. Other proteins, such as transcription factors, polymerases, and repair enzymes, also interact with DNA to regulate its functions and processes.

Organisms are living things, such as plants, animals, fungi, and bacteria, that have the ability to grow, reproduce, respond to stimuli, and maintain homeostasis. They can be unicellular or multicellular and are the building blocks of ecosystems.

The answer to that it is a consumer or a carnivore.This animal has to be at least a secondary consumer, but can also be a tertiary consumer, etc... or a scavenger.

Cork is a lightweight, buoyant material obtained from the bark of the cork oak tree. It is composed of a cellular structure that is filled with air, giving it its unique properties such as elasticity and impermeability to liquids and gases. Cork is commonly used in various applications, including wine bottle stoppers, flooring, and insulation.

Most mammals, such as dogs and cats, are believed to be colorblind and see the world mainly in shades of gray. However, some research suggests that certain animals, like monkeys and apes, have the ability to see some colors.

The tissue derived from mesoderm that lines the coelom of annelids and forms walls is called mesothelium.

No, lancelets do not have a backbone. They are small, fish-like marine invertebrates that belong to the subphylum Cephalochordata and possess a notochord instead of a true backbone.

The lungs of a fetal pig do not contain air because a developing fetus receives oxygen and nutrients from the mother's bloodstream through the placenta, not from breathing air. Therefore, there is no need for the lungs to be inflated with air until birth when the piglet starts breathing independently.

No, human females cannot sync up their menstrual cycles with female animals. Menstrual synchronization, also known as the McClintock effect, is a controversial theory that has not been scientifically proven in humans.

yes they have very good eyesight and can see up to 500 ft away

The viral reproductive cycle you are describing is called the lysogenic cycle. In this cycle, the viral DNA integrates into the host cell's chromosome, remaining dormant until it is triggered to enter the lytic cycle.

An internal nare in a frog is a passage in the oral cavity that connects the mouth to the nostrils. It plays a role in respiration by allowing the frog to breathe while keeping its mouth closed, such as when submerged in water.

Sediments produced by plants and animals in the sea are called biogenic sediments. These sediments are composed of organic remains, such as shells, corals, and skeletal debris, which accumulate on the seafloor over time.

A bird's circulatory system is efficient because it allows for rapid oxygen delivery to muscles and organs, crucial for their high metabolic rate needed for flight. Birds also have a four-chambered heart that separates oxygen-rich and oxygen-poor blood, optimizing oxygen distribution throughout the body. This system helps birds maintain high levels of energy and endurance during flight.

Sometimes mites can kill hermit crabs it depends if the mites are all over the cage and on the hermit crabs. if there are only like 3 it should not harm them as much. mites are tiny white bugs they can also be black. mites will harm the hermit crab if there are tons.

just clean your tank if you mites.

If you could see where the nest was then yes. If it hasn't been more than a day you should put the chick back inside of the nest. Leave the chick alone for at least two hours, but no more than three, being somewhat close by so you would be able to see if the parent(s) returned.

If there is no sign of the parent(s) then the chick will probably not be able to survive on his/her own. Raising the chick yourself would be difficult. For the well being of him/her, I strongly urge you to look in your local phone book for the nearest wildlife rehabilitation center and take them there.

Beetles can be found in a variety of habitats including forests, grasslands, wetlands, and deserts. They are highly adaptable and can thrive in a range of environments as long as there is food and suitable shelter available. Some beetles are specialized to specific habitats such as dung beetles in fields or water beetles in ponds.

The ductus arteriosus closes off after birth due to the increase in oxygen levels in the blood, which causes the smooth muscle in the ductus arteriosus to contract and constrict the vessel. This closure is essential to redirect blood flow away from the lungs, which are now functional after birth, and help establish the pulmonary circulation.

The inner wall of the stomach of the fetal pig is lined with gastric mucosa, which contains gastric pits leading to gastric glands. These gastric glands secrete enzymes and mucus that aid in digestion. The lining also has rugae, which are folds that allow for expansion of the stomach.
