Cactus plants, which grow in deserts, have a thick waxy coating that helps prevent water loss. The plants' sharp
spines provide protection from predators. Which of the following statements best explains why cactus plants
evolved to have these traits?
Answer:
C
Explanation:
Survival of the fittest shows that plants/animals with traits better suited for survival in their environments usually pass those traits to their offspring to help them survive.
Cactus plant with these traits were better able then other cactus plant to survive and pass these traits on to their offspring.
How do cacti adapt to the desert?Stems that can store water. Widespread or very deep root systems that can collect water from a large area or from very deep underground.
Why are cactus found in desert region?Cactus is found in dry and hot areas where rainfall is minimal and the land is arid. Their leaves are evolved into thorns to prevent transpiration and they can store water inside them.

The bacteria in a colony are unable to perform conjugation. How would this hurt the bacterial colony's chance for survival?
A. The bacteria would lose all their RNA.
B. The colony could not produce bacteriophages.
C. The colony would have less genetic variation
D. The bacteria in the colony could not reproduce.
The colony would have less genetic variation. The Bacteria in the colony would be too genetically similar
The bacteria living in a colony is aunable to perform the conjugation as they have less chances of survivial due to the colony is less genetically divere. Thus the option C is correct.
What is conjugation ?This is a process wherein organism of the same species like the bacteria, exchange the nuclear mating materials during a temporary union and are capable of transferring one consent form from one organism to another. Thus the lack of genetic variation will lead to fewer chances of species survival.

Explanation:
Why do dead zones lack the oxygen fish and other aquatic animals need to survive?
Answer:
Because most organisms need oxygen to live, few organisms can survive in hypoxic conditions. That is why these areas are called dead zones. Dead zones occur because of a process called eutrophication, which happens when a body of water gets too many nutrients, such as phosphorus and nitrogen.

C4 plants are the organisms which save water by turning carbon dioxide into a special carbon compound before carrying out photosynthesis. Thus, the correct option is B.
What are C4 plants?A C4 plant is a plant which utilizes the C4 carbon fixation pathway for carbon dioxide fixation. C₄ carbon fixation pathway or the Hatch-slack pathway is one of the three known photosynthetic processes of carbon fixation in higher plants. C4 plants are characterized by the following features such as going through the C4 carbon fixation pathway. This pathway takes place when the carbon dioxide gas is first bound to the phosphoenolpyruvate molecule in the mesophyll cells. Then, the process proceeds to the Calvin Cycle in plants.
C4 plants have a special type of leaf anatomy which is known as Kranz anatomy. These plants can tolerate high temperatures, they show a response to high intensities of light, they also lack a process called photorespiration and have greater productivity of biomass than C3 plants and CAM plants.
Therefore, the correct option is B.

Would extraterrestrial life on other Earth-like planets look similar to organisms found here on Earth?
Answer: I don't think they would since all the planets we know have completely different conditions than ours.
Explanation:
Depends on the biosphere of the other planet, any living thing on another planet would adapt to that planets resources, atmosphere, and climate. SO if that planet was almost identical to ours then maybe? We still have to factor in speed of evolution and whether or not they are put through the same events or big changes that earth life has been put through. I hope this helps!

Winter wheat is planted in the early autumn, grows over the winter when the weather
is colder, and is harvested in the spring. As the temperature drops, the composition of
the cell membrane of winter wheat changes. Unsaturated fatty acids replace saturated
fatty acids in the phospholipids of the membrane. Why is this a suitable adaptation?
Answer: It is the cell membrane will change and unsaturated fatty acids replace saturated.
Explanation:
Because unsaturated fatty acids have a kink, substituting unsaturated fatty acids for saturated fatty acids in the cell membrane of winter wheat is a suitable adaptation for the increased fluidity present in Option A.
What are unsaturated fatty acids?Cell membranes are composed of a lipid bilayer, which is made up of two layers of phospholipid molecules and consists of lipids such as saturated and unsaturated fatty acids that differ in their chemical structure, Saturated fatty acids have no double bonds between the carbon atoms in their hydrocarbon chains, while unsaturated fatty acids have one or more double bonds that provide fluidity to the plasma membrane.
Hence, substituting unsaturated fatty acids for saturated fatty acids in the cell membrane of winter wheat is a suitable adaptation for the increased fluidity present in Option A.

scientist have been measuring increasing levels of greenhouse gases in Earth's atmosphere. How do increasing levels affect the atmosphere?
Well, we have a book to write on this topic but imma explain it briefly plus simply.
Global warming emphasizes the environment with rising temperatures, water shortages, increased fire threats, droughts, weeds and pest attacks, severe storm damage and salt attacks, to name just a few.(In simple words)Now, we'd go briefly and discuss some common affects briefly :
Hotter days - The climate is getting more and more warmer and year 2015 was the hottest year ever record throughout the history. The Earth's temperature had already warmed by 1°C which is really dangerous. Rising sea levels - Rising sea levels due to climate change is the biggest problem causing natural calamities. Increased ocean temperatures are melting glaciers and ice caps all over the world. Melted ice increases the volume of water in our oceans. Warmer temperatures also result in the expansion of the water's mass, which causes sea levels to rise, threatening islands and coastal cities.More frequent and intense extreme weather - Extreme weather events like bushfires, cyclones, droughts and floods are becoming more common and more aggressive as a result of global warming.Hope it helps <3

Explain what is ecological conservation and conservation of the environment. What can you do to conserve the environment? Why do you think it is important to conserve the environment.
WILL NAME BRAINLIST!
Answer:
Conservation ecology is the branch of ecology and evolutionary biology that deals with the preservation and management of biodiversity and natural resources. Its goal is to find ways to conserve species, habitats, landscapes, and ecosystems as quickly, as efficiently, and as economically as possible.
-These are some examples of how we can conserve the environment:
Recycle your rubbish and participate in or help organize recycling campaigns.
Avoid littering and participate in or help organize litter clean-ups (here you can link to a website for volunteering or starting your own beach clean-up).
Use less plastic by, for example, carrying a reusable water bottle, saying no to disposable straws and cutlery, avoiding plastic toys, and bringing your own shopping bags (for further ideas on a plastic-free life take a look here).
Swap toys, movies, and books instead of buying new ones.
Donate, recycle, and repair electronic devices (see how here).
Use less water when brushing teeth, taking a shower, or washing the dishes.
Use less electricity by turning off lights and electronic devices when not in use, using energy-saving light bulbs, and hanging clothes to dry.
Use public transport, share a journey with friends (e.g., car-sharing), cycle, or walk when possible.
Use less paper by not printing unnecessary things and reading e-books.
Turn down the air conditioning when it is hot and use fans if you are still hot-they use much less power.
Turn down the heat when it is cold and use sweaters, blankets, and socks to keep warm.
Do not waste food and try to buy food that is grown locally and in season.
