3. A few years ago the population of male blue moon butterflies on the island of
Samoa declined. One hypothesis for the decline of the male butterflies is that a
parasite infected the cells of female butterflies. The parasite was passed to
offspring through the females' eggs and killed the male butterfly embryos. At
one point during the decline, nearly all the butterflies in the population were
females, but after five years the number of males in the population increased
significantly.
Blue Moon Butterfly.
Which explantion most likely accounts for the increase in the number of male butterflies in the five years after the initial parasite problem. Please anwser this

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!
What will happen if the DNA is not replicated?
O Mitosis will likely not occur.
Cytokinesis will occur before
mitosis.
O Mitosis will decrease the size of the cell.
O The number of chromosomes will reduce by half during mitosis.
Answer:
The cells within living organisms have the ability to grow and reproduce through the production of new cells. In order to ensure that an exact copy of the DNA is assigned to the new cells, a process called mitosis takes place. When a new cell is needed, the DNA is copied and allocated equally to new cells; then the cell splits in half. While mitosis is a precise system for distributing DNA, it is very complex and includes many cell components that must work in concert. When any one of these intricate steps fails, the results can be adverse for the cell and the whole organism.
During mitosis, a cell divides into two identical cells referred to as daughter cells. In order for both cells to be fully functional and to be able to mature, they each need a complete set of DNA. To prevent the mutations and errors in the DNA, the process has to be extremely accurate. Usually the error rate for copying DNA is around 1-3 errors for every billion base pairs. To get this extremely exact method of copying, there are many checks that happen within the process. The DNA helix unwinds and the strands separate to allow the enzymes used in replication to do their work. If the DNA strand is found to be broken or damaged, the entire process stops until it is repaired.
This process has to occur before mitosis because once mitosis starts, the cell is already preparing to divide. Soon after it begins, microtubules are forming in order to separate the newly replicated chromosomes. The DNA replication process not only has to be completed before this point, but the DNA has to be wound back up and the two copies of the same chromosome (now connected at a point in the chromosome) have to get in position so that they can be pulled apart, each destined for its new cell.

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.

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.

What is an obligate anaerobe? How do obligate anaerobe like Bacteria C get energy?
Answer:
What is an obligate anaerobe?: An organism, such as a bacterium, that can live only in the absence of oxygen.
How do obligate anaerobe like Bacteria C get energy?: Obligate anaerobes metabolise energy by anaerobic respiration or fermentation. In aerobic respiration, the pyruvate generated from glycolysis is converted to acetyl-CoA. This is then broken down via the TCA cycle and electron transport chain.

Explanation:
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
1. What organisms save water by turning carbon dioxide into a special carbon compound before carrying out photosynthesis? O photosynthetic plants O Ce plants CAM plants O photosynthetic bacteria
Answer:
I'm pretty sure its Ce plants
Explanation:
tell me if i'm wrong
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.

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.

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.
