What is the evolution of sex?
Answer:
Sex evolved as an extremely efficient mechanism for producing variation, and this had the major advantage of enabling organisms to adapt to changing environments. Sex did, however, come with a cost. In reproducing asexually, no time nor energy needs to be expended in choosing a mate.

List 3 methods of fossilization and describe the process of each
Answer:
preservation of original remains- when the original remain is still in the rock/dirt, typically shells and bones.
permineralization- when the pores of plant materials, bones, and shells are impregnated by mineral matter from the ground, lakes, or oceans
molds and casts- casts preserve a three-dimensional impression of remains buried in sediment, the mineralized impression of the organism left in the sediment is called a mold.
replacement- form when water dissolves away dead tissue and leaves minerals in its place.
compression- a fossil preserved in sedimentary rock that has undergone physical compression
petrifaction- when the organic plant or animal material is replaced with minerals and eventually hardens into rock

what Helps to maintain the plasma membranes fluidity?
Answer:
If unsaturated fatty acids are compressed, the “kinks” in their tails push adjacent phospholipid molecules away, which helps maintain fluidity in the membrane. The ratio of saturated and unsaturated fatty acids determines the fluidity in the membrane at cold temperatures.

Which type of offspring is most likely the result of asexual reproduction?
A. Offspring that inherit genes from both parents
B. Offspring that inherit only beneficial genes
C. Offspring that are genetically different from each other
D. Offspring that are genetically identical to each other
Answer:
The answer is C
Explanation:
Asexual reproduction occurs in prokaryotic microorganisms (bacteria) and in some eukaryotic single-celled and multi-celled organisms. Asexual reproduction produces offspring that are genetically identical to the parent because the offspring are all clones of the original parent.
The type of offspring that is most likely the result of asexual reproduction is the offspring that are genetically identical to each other, which is in Option D, as here the offspring are genetically identical to each other and to their parents too.
What is the significance of identical offspring in reproduction?Asexual reproduction is a process that results in offspring that are exact copies of the parent organism, as there is no involvement of the sex cells or the gametes, and without genetic recombination, identical offspring are produced. Some of the unicellular and lower-level organisms show this asexual reproduction.
Hence, the type of offspring that is most likely the result of asexual reproduction is the offspring that are genetically identical to each other, which is in Option D, as here the offspring are genetically identical to each other and to their parents too.

the role spindle during mitosis
This shows the stages in growth and division in a cell.
Answer:
A growing and dividing cell goes through a series of stages called the cell cycle. The first stages of the cell cycle involve cell growth, then synthesis of DNA. The single strand of DNA that makes up each chromosome produces an exact copy of itself. The cell undergoes a type of cell division called mitosis.
How is water consumption a problem when it comes to farming animals?
The ____ surface area exposed the ____ the weathering occurs.
A. Less, faster
B. More, slower
C. More, faster
D. Less, no change in rate
The more surface area exposed the faster the weathering occurs. Thus, the correct option is B.
What is Weathering?Weathering is the process of breaking down or dissolving of rocks and other mineral particles on the Earth's surface. Once a rock has been broken down into smaller pieces, a process known as erosion occurs which results into transport of the bits of rock and minerals away from each other. Water, acids, salt, plants, animals, and change in the temperature all are agents of weathering and erosion of particles.
Mineral weathering rates are directly proportional to the surface area of the minerals which are exposed to weathering. For example, if the rock is broken down into small pieces, it may undergo chemical weathering more readily than that of large pieces. This is because smaller pieces have more surface area for water and gases to react with the rock than the larger pieces of rocks.
Therefore, the correct option is B.

1) what is the relationship between the fundamental niche and the realized niche of a species?
PLEASE HELP
The total collection of circumstances that allow an animal (population, species) to live fundamental niche. Realized niche refers to the circumstances that a particular animal really uses.
What connection exists between a species' basic niche and its realised niche?Given its adaptations, the species' possible mode of life is known as the Fundamental Niche. The realised niche can only be the same size as or lower than the basic niche since it results from a species' adaptations as well as from competition with other species.
How do a species' innate niche and its actual niche differ from one another and what keeps them from being the same?When more creatures move in, there is competition for food and mates, or when predators begin to hunt in the area, the fundamental niche becomes smaller.

Write a paragraph explaining how energy flows through an ecosystem.
Be sure to use the following terms:
Energy Pyramid Sun
Trophic Level Producer,
Primary Consumer Decomposer
Secondary Consumer Tertiary Consumer.
Answer:
The living organisms of an ecosystem are related through food chains, which gives rise to trophic levels in an ecosystem. There is a flow of energy from one trophic level to the other in a food chain. Producers bring energy from the sun into the community. Primary consumers eat the producers, which makes them herbivores in most communities. Secondary consumers eat the primary consumers, which makes them carnivores. Tertiary consumers eat the secondary consumers. A final link in the food chain are decomposers, which break down the organic matter of the tertiary consumers (or whichever consumer is at the top of the chain) and release nutrients into the soil. Thus, there is flow of energy from Sun ------> Producer ------> Herbivore -------> Carnivore ------> Decomposers.
How energy flows through an ecosystem is summarized below.
Energy flows through an ecosystem in the following order:
Sun ----> Producer ---> Primary consumer ---> Secondary consumer ---> Tertiary consumer ---> Decomposer.
Some of the energy from the sun is fixed by the producer through a process known as photosynthesis. The producers are usually green plants and photosynthetic bacteria.Primary consumers feed directly on the producers.Secondary consumers feed on the primary consumers.Tertiary consumers feed on the secondary consumers.The decomposers feed on the remains of the tertiary consumers.As the energy flows from producer to the different consumers, and to the decomposer, only about 10% of the energy available in each trophic level move to the next with the rest being lost to heat.
Hence, an energy pyramid is created as we move from the lower trophic level to higher trophic levels.

2) The diagram below represents a change in guard cells that open and close pores in a plant. Guard cell Open pore Closed pore This change directly helps to A) regulate water loss B absorb minerals C) increase heterotrophic nutrition D) reduce seed production
Answer:
A) regulate water loss
Explanation:
Guard cells refer to the cells enclosing each stomata. They assist in monitoring the rate of transpiration by closing and opening the stomata. The guard cells possess the tendency to monitor the closing and opening of stomata by changing shape. The shape of the guard cells modifies on the basis of the concentration of potassium ions and water found in the cells themselves.
The stomatal pores get closed when carbon dioxide is no longer needed for the process of photosynthesis. The guard cells swell when movement of water takes place inside these pores, and thus, the opening of stomatal pores occurs, and as water moves out, the guard cell closes. Thus, guard cells play an essential role in regulating water loss.

Answer:
Overabundant deer can spell trouble for people, including frequent car collisions and the spread of zoonotic diseases. But deer can also disrupt wildlife communities -- such as forest songbirds -- by eating away their habitat. In a new study, researchers show that areas in the eastern US with high deer numbers tend to have fewer birds that need forest shrubs.
