What are some negative impacts of having this life cycle that might have contributed to a decline in the dragonfly population?
Answers
Answer:
Dragonflies are important for our environment.
Explanation:
Dragon flies belongs to the ancient family of insects. They are found on every parts of the world and have been from around 300 millions years ago. There are more than 5000 different species of them found in different parts of the world. Conserving dragonflies is important as they considered as a valuable environmental indicators.
Dragon flies are found in the areas where water is available and near grasslands. Their life cycle is an example of an incomplete metamorphosis. The dragon flies lays their eggs near the water or in the water. Dragon flies spends most of the life time as a nymph in the water where they turn into an adult and leave the water. The dragon flies rely on the aquatic ecosystems all through their life. Thus dragonflies are an important indicators of the environment and water quality.
Most of the life cycle of the dragon flies depend on the availability of water and its quality. Polluting water and destroying their habitat will result in the decline of the population of the dragon flies.

Identify, analyze, and relate the internal (Earth) and external (astronomical) conditions that contribute to global climate change. Include ultraviolet rays, ozone layer, CO2 in the atmosphere etc PLZZZZZZ HELP
Answers
Answer:
Carbondioxide gas is responsible for global warming and climate change.
Explanation:
The climate change mostly occur due to increase in the concentration of carbondioxide gas in the atmosphere. The CFCs gases causes depletion of ozone layer in the atmosphere which is responsible for prevention of ultraviolet rays coming to the earth. The burning of fossil fuels in the vehicles and industries produces huge amount of carbondioxide gas that is released in the atmosphere that allows the sunlight to the earth but block its way after reflection which remain suspended in the lower surface causes increase in temperature which leads to global warming.

v-FLIPs are viral proteins that were first identified as modulators of apoptosis; they contain two death effector domains, which are also found in some initiator caspases such as procaspase-8. These v-FLIP proteins can be recruited to the DISC through the binding of the death effector domain to similar domains in the adaptor proteins but are otherwise catalytically inactive. What do you think is the effect of v-FLIP expression in the host cell?A. It promotes apoptosis mainly via the extrinsic pathway.B. It inhibits the extrinsic pathway of apoptosis.C. It activates only the mitochondrial pathway of apoptosis.D. It inhibits the intrinsic pathway of apoptosis.E. It enhances the caspase cascades in both the intrinsic and extrinsic pathways.
Answers
Answer:
B. It inhibits the extrinsic pathway of apoptosis
Explanation:
Apoptosis is a cellular pathway that leads to programmed cell death. Viral FLICE-inhibitory proteins (FLIPs) bind to the adaptor proteins and block the interaction between the DISC complex with the caspase-8 protease enzyme, which triggers apoptotic cell death. In consequence, cells become resistant to Fas-mediated apoptosis, a pathway initiated by the FADD protein which is known to recruit caspase-8.
What are the three types of forests age and structure?
Answers

Tropical rain forests grow around the equator in South America, Africa, and Southeast Asia, The temperature is stable year-round, around 27°C (60° Fahrenheit). As you can tell from the name, it rains a lot in these forests. Most tropical forests receive at least 200 cm (80 inches) of rain in a year. Tropical forests generally have a rainy and dry season. Temperate forests occur in the next latitude ring, in North America, northeastern Asia, and Europe, temperature ranges from -30 to 30°C (-22 to 86 F) and the forests receive 75-150 cm (30-60 in) of precipitation per year,

Answers
Answer:
Life on Earth began more than 3 billion years ago, evolving from the most basic of microbes into a dazzling array of complexity over time. But how did the first organisms on the only known home to life in the universe develop from the primordial soup? One theory involved a "shocking" start. Another idea is utterly chilling. And one theory is out of this world! Inside you'll learn just how mysterious this all is, as we reveal the different scientific theories on the origins of life on Earth.Electric sparks can generate amino acids and sugars from an atmosphere loaded with water, methane, ammonia and hydrogen, as was shown in the famous Miller-Urey experiment reported in 1953, suggesting that lightning might have helped create the key building blocks of life on Earth in its early days. Over millions of years, larger and more complex molecules could form. Although research since then has revealed the early atmosphere of Earth was actually hydrogen-poor, scientists have suggested that volcanic clouds in the early atmosphere might have held methane, ammonia and hydrogen and been filled with lightning as well. The first molecules of life might have met on clay, according to an idea elaborated by organic chemist Alexander Graham Cairns-Smith at the University of Glasgow in Scotland. These surfaces might not only have concentrated these organic compounds together, but also helped organize them into patterns much like our genes do now. The main role of DNA is to store information on how other molecules should be arranged. Genetic sequences in DNA are essentially instructions on how amino acids should be arranged in proteins. Cairns-Smith suggests that mineral crystals in clay could have arranged organic molecules into organized patterns. After a while, organic molecules took over this job and organized themselves.
