hope this is what you were looking for!:)
A food chain refers to the order of events in an ecosystem, where one living organism eats another organism, and later that organism is consumed by another larger organism. The flow of nutrients and energy from one organism to another at different trophic levels forms a food
What is food chain ?The wild food chain outlines who consumes whom. From single-celled algae to enormous blue whales, all living things depend on food to thrive. Energy and nutrients may travel through the ecosystem along any number of food chains. For instance, grass makes its own sustenance out of sunshine. Eats grass is a rabbit.
A network of food chains that are connected to one another is referred to as a food web. A food chain has a specific order in which each component is consumed by the others. A component of the food web are the producers, consumers, and decomposers of different food chains.

which safety practice is required for children under 7 years of age while underway on the open deck of any vessel?
When children under 7 years of age are underway on the open deck of any vessel, it is typically required for them to wear a United States Coast Guard (USCG) approved personal flotation device (PFD).
This safety practice is crucial to ensure the safety and well-being of young children while on board a vessel. In addition to wearing a PFD, other safety practices for children on board a vessel include close adult supervision, educating children about basic boating safety rules, and teaching them how to behave responsibly and calmly while on the water.
The USCG regulations require that children under 13 years of age wear a properly fitted PFD while the vessel is underway on the open deck. However, specific age requirements and regulations may vary depending on the jurisdiction and local laws. It is important to familiarize yourself with the specific regulations and requirements of the area where you are boating or operating a vessel.
The PFD or life jacket should be appropriate for the child's size and weight, and it should be in good condition, properly fastened, and worn at all times while on the open deck. It is also recommended to ensure that the PFD is approved by a recognized authority and suitable for the intended water activities and conditions.

what type of ecosystem will be harmed by flushing chemicals down the drain
Answer:
Oxygen Depletion
Explanation:
In addition to the eutrophication of water bodies, wastewater effluents also contribute to another process of deoxygenation. The biological (bacterial) breakdown of organic solids in the effluent also consumes dissolved oxygen – the biological oxygen demand (BOD). In addition, the degradation of chemicals in the effluent removes oxygen from the water through chemical reactions – the chemical oxygen demand (COD).
As was previously mentioned, the loss of dissolved oxygen in the water can result in serious immediate, short-term, or long-term consequences to aquatic life. Fish survival is particularly affected by low oxygen levels. Decreased disease resistance, reduced growth, altered swimming behaviour, feeding, migration, and reproduction, increased threat of predation, and even rapid death are some of the effects of low dissolved oxygen concentrations.
Low oxygen levels can also alter the kinds of species present in the ecosystem. With a change in food supply, some populations of species decrease, while others increase. Fish such as whitefish, walleye, and pike may disappear, while bottom-feeding fish such as carp may increase in number.

and Golgi apparatus.
3. What is the main difference between rough endoplasmic reticulum and smooth endoplasmic reticulum?
4. Describe the three types of vesicles.
Answer: 1 Lysosomes and peroxisomes, Microtubules, Endoplasmic reticulum, Mitochondria
2 The role of the nucleus of a eukaryotic cell is to control the cell. Because it contains most of the cell's DNA, which is encoded with genetic instructions, the nucleus controls which proteins the cell makes.
3 The rough endoplasmic reticulum has ribosomes on its surface. This is what give the RER a "rough" appearance. The smooth endoplasmic reticulum (SER) does not contain ribosomes. The Smooth ER looks more like tubes. The SER helps in the storage of proteins and lipids.
4 Secretory vesicles contain materials that are to be excreted from the cell, such as wastes or hormones.
Transport vesicles move molecules within the cells.
Vacuoles are vesicles that contain mostly water.

urinary flow in men can be compromised by enlargement or growth of what gland? a. prostate b. adrenals c. kidneys d. pancreas e. spleen
The urinary flow in men can be compromised by enlargement or growth of the prostate gland (option a).
The prostate gland is a small gland located below the bladder and surrounds the urethra, the tube that carries urine from the bladder out of the body. As men age, the prostate gland can undergo a non-cancerous condition known as benign prostatic hyperplasia (BPH).
In BPH, the prostate gland gradually enlarges, putting pressure on the urethra and obstructing the normal flow of urine. This can lead to symptoms such as difficulty starting urination, weak urine flow, frequent urination (especially at night), and a feeling of incomplete bladder emptying.
