Answer:
A. Spores
B. Meiosis
C. Spores grow by mitosis into gametophyte
D. Haploid (n)
E. Gametes (sperm and egg)
F. Mitosis
Explanation:
Alternation of generations is a system of life cycle exhibited by certain organisms such as algae, plants etc where they alternate between a haploid phase/generation and diploid phase/generation. In this life cycle, the SPOROPHYTE is the diploid (2n) multicellular body that forms haploid SPORES via meiotic division. These spores, however, grow into another multicellular body via mitosis called GAMETOPHYTE.
The GAMETOPHYTE refers to the haploid (n) body that produces the haploid gametes (sperm and egg) by undergoing mitosis. The haploid gametes produced unites in a process called FERTILIZATION to yield a diploid ZYGOTE that eventually mitotically grows into the SPOROPHYTE. Note that, the cycle repeats.

Answer:
A is correct
Explanation:
Story #1
Once upon a time, there lived a population of mountain people whose members all had wings but different
types-either bat wings or bird wings. 40% of the population had bat wings and 60% of the population had bird
wings. One day, a storm hit that lasted for several weeks. Those with bat wings were able to fly around and
find food because their wings were water resistant, while those with bird wings were not able to get food
because their feathers were not water resistant and got soaked through. Many of the bird-winged people starved
and did not survive, so their alleles decreased in the gene pool, lowering the frequency of the bird wings in
future generations. Over many generations, the environment had more and more long periods of rain and the
genetic makeup of the population shifted to 10% with bird wings and 90% with bat wings.
What is the trait being described?
What are the variations that exist in this population?
3. How did the event lead to the change in allele frequency?
Alleles?
4. What type of evolutionary mechanism did this story show?
5. Was there an adaptation in this story? If so, identify it.
6. Did the change make the population more or less similar to other populations?
7. Would this increase or decrease reproductive isolation?
Increase or decrease speciation?
8. Did the new population change for the better, worse, or have no effect? Why?
Answers
Answer:
The trait being described is the ability to fly in rainy season.
Explanation:
The trait being described is the ability to fly in rainy season. The people with bat wings and people with bird wings are present in the population. The event lead to the change in allele frequency because the population of people with bird wings die due to starvation. Yes, the bat wings were adapted to that environment so they are able to survive. The change make the population less similar to other populations because population of people with bat wings increases as compared to other population. Yes, the new population change for the better of the ecosystem because the population is able to controls the population of other species in the ecosystem.

The most common adaptation is the presence of lightweight internal packing cells, aerenchyma, but floating leaves and finely dissected leaves are also common. Aquatic plants can only grow in water or in soil that is frequently saturated with water. They are therefore a common component of wetlands.

What are some of the WORST things about coal fuel?
help me please help me
Answers
Answer:
Explanation:
The burning of fossil fuels releases greenhouse gases into the atmosphere, increasing levels of CO2 and other gasses, trapping heat, and contributing to global climate change. Coal combustion releases the greenhouse gases carbon dioxide (CO2) and nitrous oxide (N2O) during combustion. The major disadvantage of coal is its negative impact on the environment. Coal-burning energy plants are a major source of air pollution and greenhouse gas emissions. In addition to carbon monoxide and heavy metals like mercury, the use of coal releases sulfur dioxide, a harmful substance linked to acid rain.
Answer:
Air pollution
Can impact health of citizens like asthma, breathing difficulties, etc.
Can lead to death if not treated or fixed.
Releases greenhouse gases into the atmosphere.
Contributes to global climate change.

Which of the following is typical of aerobic respiration?
decreases a plant’s weight
contains two stages, glycolysis and fermentation
produces methane as a byproduct
produces little energy
Answers
Answer:
decreases a plant’s weight
Explanation:
Aerobic respiration is a process of respiration in which oxygen is required and the byproducts of aerobic respiration are carbon dioxide, water and energy.
Plants undergo aerobic respiration and it is a catabolic process in which complex compounds in plants turns into simpler compounds. This process reduces the dry weight of the plants.
Glycolysis is the first step in both aerobic and anaerobic respiration so it is not a typical aerobic respiration.
Hence, the correct answer is "decreases a plant’s weight".

Answers
The first stage of human decomposition is called autolysis, or self-digestion, and begins immediately after death. As soon as blood circulation and respiration stop, the body has no way of getting oxygen or removing wastes. Excess carbon dioxide causes an acidic environment, causing membranes in cells to rupture. The membranes release enzymes that begin eating the cells from the inside out.
Rigor mortis causes muscle stiffening. Small blisters filled with nutrient-rich fluid begin appearing on internal organs and the skin’s surface. The body will appear to have a sheen due to ruptured blisters, and the skin’s top layer will begin to loosen.
Stage Two: Bloat
Leaked enzymes from the first stage begin producing many gases. The sulfur-containing compounds that the bacteria release also cause skin discoloration. Due to the gases, the human body can double in size. In addition, insect activity can be present.
The microorganisms and bacteria produce extremely unpleasant odors called putrefaction. These odors often alert others that a person has died, and can linger long after a body has been removed.
Stage Three: Active Decay
Fluids released through orifices indicate the beginning of active decay. Organs, muscles, and skin become liquefied. When all of the body’s soft tissue decomposes, hair, bones, cartilage, and other byproducts of decay remain. The cadaver loses the most mass during this stage.
Stage Four: Skeletonization
Because the skeleton has a decomposition rate based on the loss of organic (collagen) and inorganic components, there is no set timeframe when skeletonization occurs.
What type of evolutionary mechanism did this story show?
Answers
Allele frequencies in a population may change due to four fundamental forces of evolution: Natural Selection, Genetic Drift, Mutations and Gene Flow. Mutations are the ultimate source of new alleles in a gene pool. Two of the most relevant mechanisms of evolutionary change are: Natural Selection and Genetic Drift.
This story showed an example of convergent evolution. Convergent evolution is the process whereby organisms that are not closely related independently evolve similar traits as a result of having to adapt to similar environments or ecological niches.
What is in the story ?In this story, the two species of birds, the crows and the jays, evolved to look similar as a result of living in the same environment and competing for the same resources.
The two species evolved to look similar in order to blend in with their environment, making it difficult for predators to distinguish them from one another. This allowed them to survive and thrive in the same environment.
Therefore, This example of convergent evolution is a perfect example of how species can evolve to look similar in order to survive in the same environment. It also shows how competition for resources can drive species to evolve similar traits in order to survive.

Some fungi and insects benefit each other; the fungi protect the insects from predators and the insects spread spores for the fungi. This is an example of a mutualistic relationship.
What is a Mutualistic relationship?A mutualistic relationship may be defined as a +,+ type of interaction in which both species benefit from the existence of each other. Example includes lichens, mycorrhizae association, coral reefs, etc.
In the question, the Fungi protect the insects from predators and benefit the insects to get survivability, while in return insects spread spores for the fungi and assist them in their reproduction process.
Therefore, both insects and fungi undergo a mutualistic type of relationship through which both species benefit from the existence of each other.
