Steve Irwin's mother, Lyn Irwin, passed away from natural causes in 2000. Steve Irwin's mother died in a car accident in 2000.

Most mammals have estrous cycles while humans have menstrual cycles because when the uterine lining breaks down in humans, it needs to escape the body while in other mammals it is absorbed back into the body instead of flowing out of the body as menses.

Most mammals feel a great desire to have sex whenever they are fertile or when they are in the presence of a fertile male. But for humans, we could have the desire to have sex in any part of the month. Female humans tend to feel an even greater desire for sex during their period.

you group them by their size habitats and where they come from

In an energy storage molecule like adenosine triphosphate (ATP), the energy is stored in the bonds between the phosphate groups. When these bonds are broken, energy is released for cellular processes.

Snails need to keep moist to prevent dehydration. Their bodies are primarily composed of water, and they rely on a thin layer of mucus to retain moisture and stay hydrated. If snails dry out, it can lead to serious health problems and even death.

Yeast is part of the fungus kingdom.

Pretty much all plant organisms can produce their own food. However, organisms like mushrooms are often confused for plants, but they CANNOT make their own food.

Mushrooms are fungus, meaning that they have to get their food from other dead or decaying organisms. This makes them different from both plants and animals because they don't eat food, but they don't make it for themselves either. They absorb it through their roots.

Yes, drinking herbicide can be fatal as it is toxic to humans. Herbicides contain chemicals that can cause damage to the digestive system, central nervous system, and other organs in the body. Ingesting a large amount of herbicide can lead to severe poisoning and potentially death.

No, not all living things vomit. Vomiting is a physiological response that some animals have evolved to expel harmful substances from their stomachs. Organisms like plants and certain simple organisms do not have the ability to vomit.

Animals have several characteristics that set them apart from other living things. Animals are eukaryotic and are multicellularwhich separates them from bacteria and most protists. They are heterotrophic,generally digesting food in an internal chamber, which separates them from plants and algae.They are also distinguished from plants, algae, and fungi by lacking rigid cell walls. All animals are motile, if only at certain life stages. In most animals, embryos pass through a blastula stage, which is a characteristic exclusive to animals.

Brain corals are radial symmetrical, meaning they have multiple planes of symmetry that pass through a central axis. This symmetry allows them to grow in a circular or dome-like shape, with their feeding tentacles extending outwards in all directions.

Yes, plant cells contain ribosomes. Ribosomes are responsible for protein synthesis in a cell, which is essential for various cellular functions, including growth and repair. Plant cells, like all eukaryotic cells, have ribosomes in their cytoplasm and on their endoplasmic reticulum.

Hermit crabs are omnivores and can eat a variety of foods including fruits, vegetables, nuts, seeds, and small bits of meat or fish. It's important to provide a balanced diet that includes calcium-rich foods for their shell health. Commercial hermit crab food is also available and can be supplemented with fresh foods for a well-rounded diet.

You could use a stereo microscope, also known as a dissecting microscope, to observe organisms found in pond water. This type of microscope provides a three-dimensional view of larger specimens at lower magnifications.

If a prime mover produces flexion, its antagonist will be the muscle responsible for producing extension at the same joint. They work in opposition to each other to create movement and stabilize the joint.

Epithelial cells would be best suited as a covering of an organ due to their protective function and ability to form tight barriers. They can be simple (one layer) or stratified (multiple layers) depending on the organ and its needs. Epithelial cells make up the outer layer of skin, the lining of blood vessels, and many other protective coverings in the body.

Yes, dogs are capable of hearing high frequency sounds that are beyond the range of human hearing. Their ears are sensitive to frequencies up to 65,000 Hz, compared to humans who can typically hear up to 20,000 Hz.

Butterflies help the environment by pollinating flowers as they feed on nectar, aiding in the reproduction of many plant species. They also serve as a food source for other animals, contributing to the overall biodiversity of an ecosystem. Additionally, their presence can indicate the health of an ecosystem, as they are sensitive to changes in habitat and climate.

The human eye is an organ because it is a specialized structure made up of different tissues working together to perform a specific function, which is to detect light and convert it into electrical signals that can be interpreted by the brain. Additionally, the eye has a well-defined structure with distinct components such as the cornea, iris, lens, retina, and optic nerve, all of which play crucial roles in the visual process.

Father Junipero Serra established a mission at San Diego in 1769.

Bacteria reproduce through binary fission, a form of asexual reproduction

Foie gras has a rich, buttery flavor with a delicate, melt-in-your-mouth texture. It is often described as being savory, with a subtle sweetness and a hint of earthiness.
