Calculate how much DDT you would consume if you ate 3 kg of squid (calamari).
Answer:
66 000 mg or 66g
Explanation:
If a person consumes 3 kg of squid, the amount of DDT consumed cannot be confirmed because the amount and concentration of DDT vary; for example, if the squid is caught in an area where DDT is widely used, the squid contains more DDT.
What effect does DDT have on animals?DDT is commonly used in pest control, but it is eventually replaced by other chemicals due to its numerous environmental side effects, which include the thinning of eggshells in birds, accumulation in the fatty tissues, disruption of the endocrine system of animals, etc., and being highly toxic to animals and birds, etc.
Hence, if a person consumes 3 kg of squid, the amount of DDT consumed cannot be confirmed because the amount and concentration of DDT vary; for example, if the squid is caught in an area where DDT is widely used, the squid contains more DDT.

Salt water is an abundant resource but unusable for irrigation and drinking. As demands on freshwater sources increase, the use of desalination processes to remove salt from ocean water is increasing. A concern of desalinating water is the large amounts of recovered salts that are returned to the ocean. Which of the following describes the most likely impact of desalination on the surrounding ocean environment?
Options are not provided in the question. The complete question is as following:
Salt water is an abundant resource but unusable for irrigation and drinking. As demands on freshwater sources increase, the use of desalination processes to remove salt from ocean water is increasing. A concern of desalinating water is the large amounts of recovered salts that are returned to the ocean. Which of the following describes the most likely impact of desalination on the surrounding ocean environment?
A. Methane gas would pollute the ocean environment as shoreline organisms begin to die and decay.
B. Alteration in ocean salt levels would cause loss of species and unbalanced populations in marine food webs.
C. Nonrenewable resources in the ocean environment would become depleted and upset the ecosystem's balance.
D. Increased levels of salts and minerals in the ocean would result in overpopulation of marine bivalves due to strengthened shells.
Answer:
B.
Explanation:
Desalination is done to fulfill the requirement of freshwater from ocean water and then the recovered salts are returned to the ocean, which affects the ocean environment. It majorly impacts the loss of species and unbalanced populations in marine food webs due to continuous alteration in ocean salt levels.
All the animals are dependent on the habitat or external abiotic factor for their survival and any change in the habitat or abiotic condition such as temperature, pressure and salinity causes change in their existence. The marine animals depend on ocean water for their survival, some of the activities that depend on salinity of water are egg fertilization and incubation, early embryogenesis, yolk sac resorption, larval growth and swimbladder inflation.
If salinity of ocean increases, all the activities of marine organism will disturbed which will result into loss of marine species and further lead to unbalance the populations in marine food webs
So, change in salinity (abiotic factor) will definitely affect the marine organism.
Hence, the correct option is B.

Why do you think naming the lynx might be advantageous for its survival? (please help)
Answer:
Lynx are wild animals, which act as predators in regulating the populations of their prey.
Lynx are dangerous for humans but humans are more dangerous for them because they are hunted for their skin.
Naming the lynx will be advantageous for its survival because it will give them a unique identity and will increase care for them. Naming the animal create a different bond between human and animals which changes the way humans regard animals.
So, naming the lynx might decrease the hunting of lynx and will increase its chnaces to survive.

State lab review packet answers diffusion through a membrane -beaks of finches - making connections - relationships and bio diversity
Answer:
Diffusion can happen with or without a membrane. It always takes place down a concentration gradient, which means the substance will diffuse from an area of higher concentration to an area of lower concentration.
Biodiversity is critical to maintaining the balance of the ecosystem. Without a diverse collection of organisms, the species in the environment cannot thrive and are at a risk of extinction in extreme cases.

Why do carnivorous plants eat insects?
Answer:
Meat-eating, or carnivorous, plants can trap and digest insects and other small animals. They do this to obtain the vital nitrogen that they need to grow. Most plants absorb enough nitrogen from nitrates in the soil. Carnivorous plants live in bogs, where nitrates are in short supply, so they need to obtain their nitrogen by digesting prey instead. Carnivorous plants have developed unique ways to catch insects, such as fluid-filled PITCHERS and spring-loaded traps.

What is the connection between the rising concentration of SO2 And NO2x , And The Acid Rain Pollution Alert?
Answer:
Acid rain refers to the rain which acidic in nature having a form of precipitation and elevated levels of hydrogen ions (low pH). The normal pH of rain is around 5.6
Rising concentration of Sulfur dioxide (SO2) and nitrogen oxides (NOx) in atmosphere is one of the cause of acid rain. Sulfur dioxide (SO2) and nitrogen oxides (NOx) are released by vehicles, fossil-fuel power plants and oil refineries.
When a sulfur dioxide and nitrogen oxides released in air they mix with oxygen, water and other chemicals in the air and form sulfuric and nitric acids. sulfuric and nitric acids mix with precipitation and its pH level is about 5.2 or below.
Hence, rising concentration of SO2 And NO2x is one of the biggest reason of acid which damages agriculture, buildings and wildlife et-cetra.
