Answer:
Fertilization would result in a zygote with twice as many chromosomes as the parents.
Explanation:
Meiosis creates four haploid cells from a diploid parent cell. These haploid cells are the sex cells - sperm cells and egg cells.
Since these cells are haploid (containing 23 chromosomes, half the amount of chromosomes as the parent diploid cells), when they fuse during fertilization, they form a diploid zygote containing 46 chromosomes.
Answer:
B) Fertilization would result in a zygote with half as many chromosomes as the parents.

What structures could you see under high power that you could not see under low power?
Answer:
The field of view is widest on the lowest power objective. When you switch to a higher power, the field of view is closes in. You will see more of an object on low power.

Northern Arizona University › lessons
Microscope Notes
The depth of focus is greatest on the lowest power objective. Each time you switch to a higher power, the depth of focus is reduced. Therefore a smaller part of the specimen is in focus at higher power.
The amount of light transmitted to your eye is greatest at the low power. When you switch to a higher power, light (and therefore resolving power, or the ability to distinguish two nearby objects as separate) is reduced. Compensate with the light control (sometimes called the iris diaphragm

Which of the following is not a reason that nonnative species are reared outside their native ecosystems?
a. They are commercially important.
b. They are used to replace native species.
C. They are used for restocking programs.
d. None of the above
Answer:
D
Explanation:
All of the given reasons are reasons that nonnative species are reared outside their native ecosystems. The correct option is D.
What are nonnative species?Non-native species are animals, plants, and other organisms that do not develop natively in a region but are instead introduced through intentional or unintentional human activity.
Non-native species, unlike invasive species, do not necessarily threaten or threaten the existence of other species within the ecosystem.
Native plants and animals may go extinct as a result of invasive species, which can also decrease biodiversity, compete with native species for scarce resources, and disrupt habitats.
Ecosystems along the coast and in the Great Lakes may be severely disrupted, with significant negative economic effects.
They are employed in restocking efforts, to replace native species, and for commercial purposes.
Thus, the correct option is D.

Why is the cycling of elements and nutrients important
Answer:
Nutrient cycles allows the transformation of matter to different specific forms that enables the utilisation of that element in different organisms. ... Therefore, nutrient cycles enable the provision of elements to organisms in forms that are usable to them. Transfer of elements from one location to another.
Explanation:
It is required for the conversion of nutrients from one form to another so that they can be used by various organisms.
What is recycling of elements?The transport and transformation of chemicals within and between ecosystems is known as element cycling, and it is a major focus area for ecosystem scientists.
Any of the natural pathways through which essential elements of living matter circulate is referred to as a biogeochemical cycle.
The term biogeochemical is an abbreviation for considering the biological, geological, and chemical aspects of each cycle.
A natural process in which elements in various forms are continuously cycled between different compartments of the environment.
Plants play an important role in several key processes that occur in the Earth's interacting systems, including the hydrosphere, atmosphere, and biosphere.
The water cycle, the nitrogen cycle, and the carbon cycle are all examples of cycles.
Thus, the cycling of elements and nutrients seems to be essentially important.

Trees
Question: What role do trees play in the forest?
1. Form hypothesis: Where do you think trees get the nutrients they need to grow?
2. Predict: Based on your hypothesis, how will the tree population change if ALL other organisms (deer,
bears, and mushrooms) are removed from the forest?
3. Analyze: Remove ALL organisms except trees. Click Advance year a few times and select the DATA
tab. Was your prediction correct? Explain what you found.
4. Draw conclusions: Substances that contain carbon and are produced by living things are called
organic. Examples of organic materials are sugar, blood, protein, and fat. Other materials, like water.
Answer:
Form hypothesis: Where do you think trees get the nutrients they need to grow?
I think the trees get the nutrients from the soil and sunlight
Predict: Based on your hypothesis, how will the tree population change if ALL other organisms (deer, bears, and mushrooms) are removed from the forest?
I think they will increase dramatically because there is nothing affecting them badly.
Analyze: Remove ALL organisms except trees. Click Advance year a few times and select the DATA tab. Was your prediction correct? Explain what you found.
Yes my hypothesis was correct without the other organisms affecting the trees growth the tree population increased.
Draw conclusions: Substances that contain carbon and are produced by living things are called organic. Examples of organic materials are sugar, blood, protein, and fat. Other materials, like water, carbon dioxide, oxygen, and ammonia, are called inorganic.Some living things, called producers, can produce the organic materials they need (like food) from inorganic matter. All other organisms are consumers; they consume organic matter since they cannot make it themselves.
Do your results show you that trees are producers or consumers? Explain.
Trees are producers because they make it by using the sun's light.
Analyze: Click the FOREST tab. Click the plus (+) button for mushrooms several times. Click Advance year a few times. Select the DATA tab. How did adding mushrooms affect trees?
adding the mushrooms didn’t affect the trees.
Extend: The mushrooms thrived without hurting trees. How could this happen? Try for two possible explanations. Write your ideas in the space below.
The mushrooms are decomposers; they thrive off of dead things including the trees so they do not harm the trees at all.
Explanation:
The trees in the forest controls the flow of water on the land.
When heavy rainfall occurs the trees help in trapping the water in the soil which reduces the chances of flood. These trees also provide habitat as well as food for living organisms that lives in the forests.
The trees get the nutrients they need to grow from the soil with the help of their roots. Decomposers present in the soil feed on dead bodies which turn into nitrogenous substances that is used by the trees for making amino acids.
The tree population increases if all other organisms such deer, bears, and mushrooms are removed from the forest because these organisms feed on the trees so increase occur in the tree population.

In pea plants, the allele for round seeds is dominant to the allele for wrinkled seeds. If a plant that is heterozygous for seed type is crossed with one that has only homzygous wrinkled seeds, what percent of their offspring would you expect to have wrinkled seeds?
Answer:
50%
Explanation:
According to this question involving a gene coding for seed shape in pea plant, the allele for round seeds (R) is dominant to the allele for wrinkled seeds (r). This means that a heterozygous pea plant (Rr) will have a round seed shape.
If a plant that is heterozygous for seed type (Rr) is crossed with one that has only homzygous wrinkled seeds (rr), the following gametes will be produced by each parent plant:
Rr - R and r
rr - r and r
Using these gametes in a punnet square (see attached image), the following proportions of offsprings will be produced:
Rr, Rr, rr and rr
Rr = round seed offsprings
rr = wrinkled seed offsprings
Since 1 out of 2 offsprings has wrinkled seeds, 1/2 × 100 = 50% is the percentage of offsprings expected to have wrinkled seeds.

How are elements in the same period in the periodic table alike?
A. They have the same atomic number.
B. They have the same number of electron shells.
C. They have similar chemical properties.
D. They have the same atomic mass.
Answer:
C
Explanation:
The elements in the same period in the periodic table alike and they have similar chemical properties. Thus, option C is correct.
What is Groups and Periods in Periodic Table ?In periodic table there are 18 vertical column which is called groups which are arranged from left to right in the periodic table. In periodic table there are 7 horizontal rows which is called periods.
Elements in the same family or group have a similar chemical properties because they have the same number of valence electrons. In group one all the alkali metals have one valence electrons in the outermost shell.
Thus from the above conclusion we can say that Elements in the same family have a similar chemical properties because they have the same number of valence electrons this statement is true about elements on a periodic table in the same group.
Therefore, The elements in the same period in the periodic table alike and they have similar chemical properties. Thus, option C is correct.

Why is it more likely that a sea cave becomes a sea arch before becoming a sea stack?
Answer:
Based on my research, I'd say it becomes a Sea arch before becoming a Sea stack due to the breaking waves erode, or wear away, the rock at sea level bit by bit, forming arches. Softer rock falls away more quickly than harder rock.
Explanation:
A sea stack is a pillar of rock that is cut off from the headland or cliff. When the waves erode the base of the sea arch, they widen it. Eventually, the roof is unable to support itself and it collapses, the former tip of the headland cut off as a sea stack.
