A woman has an extra X chromosome. Explain how this happened using what you have learned in this lesson. Describe the error in gamete formation, identify the stage of meiosis where the error could occur, and explain the consequences of the error in meiosis
Answer:
can occur during meiosis I or meiosis II, in meiosis I homologous chromosomes fail to separate or in meiosis II the sister chromatids fail to separate
Explanation:
Answer:
Meiosis is the formation of gametes
One error in meiosis is nondisjunction.
Nondisjunction results in an abnormal number of chromosomes.
Nondisjunction in meiosis I result in 50% of gametes with an extra chromosome.

How do different processes of the
rock cycle change a rock? Which
processes will form an igneous,
sedimentary, and metamorphic
rock?
Answer:
Igneous rocks are formed from cooled magma, magma is formed from melted metamorphic rock, metamorphic rock is formed from either heated igneous rock or heated and pressurized sedimentary rock, sedimentary rock is formed from sediments throught compaction and cemenetaion and sediments are formed from weathered and eroded igneous or metarmorphic rocks
Explanation:
For more info look up rock cycles and hit images for a simple format
Answer:
Volcanic activity- Igneous, such as granite, basalt, or obsidian
Heat and pressure of already formed rock- Metamorphic, such as slate or marble
Layers of sediment, sand, and silt under pressure- Sedimentary- such as shale, limestone, or sandstone
Explanation:
It takes thousands to millions of years for these to form (except maybe for igneous rocks, because the magma or lava just has to cool).
Those were parts of the rock cycle that changes the rocks.

2. A stomach cell-would be an example of a starting cell in this
process.
Answer:
mitosis
Explanation:
A stomach-cell would be an example of mitosis.
What do you mean by mitosis?Mitosis is a part of the cell cycle in which replicated chromosomes are separated into two new nuclei. Cell division by mitosis gives rise to genetically identical cells in which the total number of chromosomes is maintained.
Mitosis is a way of making more cells that are genetically the same as the parent cell. It plays an important part in the development of embryos, and it is important for the growth and development of our bodies as well.
These phases are prophase, prometaphase, metaphase, anaphase, and telophase.

A vase is sitting on a table.
What, if any, forces are acting on the vase? (If there are forces acting on the vase, include what direction they are acting.)
Answer:
Gravity is one force
Explanation:
Gravity in which holds the vase down onto a surface could be an acting force to keep it from tipping or floating from the table. The gravitational pull in an idle vase on a table would be naturally. Going. Downward.
What molecule does plants use to absorb energy
Answer:
The chlorophyll molecule.
Explanation:
This is an important part of the photosynthesis process -- it can absorb energy from incoming light. This molecule absorbs all light except green light -- they primarily absorb red, blue, or yellow light. That's why a plant looks green to our eyes, because the color not absorbed by the plant is reflected to us.
why does the number of yeast cells decrease during fermentation??
Answer:Dough can still rise in cooler environments, but much more slowly. Amount of yeast; the more yeast the faster the fermentation. Too much can add an undesirable yeasty flavor.

How do the steps of mitosis help cells divide?
Answer:
Mitosis is the process in which the cell divides.

Describe how these three types of soil differ in terms of particle size, water-holding capacity, and
surface area for nutrient absorption by roots.
Answer:
Soils with smaller particles (silt and clay) have a larger surface area than those with larger sand particles, and a large surface area allows a soil to hold more water. In other words, a soil with a high percentage of silt and clay particles, which describes fine soil, has a higher water-holding capacity.

In pea plants, purple flowers (F) are dominant over white flowers?
If two pea plants with genotypes of Ff and ff reproduced, what percentage of the offspring would be predicted to have white flowers?
A. 100%
B. 0%
C. 75%
D. 50%
E. 25%
Pink snapdragon flowers are a result of incomplete dominance. What genotype would the pink snpdragons have?
A. Ff
B. FF
C. ff
Answer:
1. If two pea plants with genotypes of Ff and ff are reproduced, the prediction of the percentage of the offspring that will have white flowers is 50% (option D).
2. Because pink snapdragon flowers are the result of incomplete dominance, the genotype that pink snapdragons would have is Ff (option A).
Explanation:
1. Knowing that in pea plants purple flowers (F) are dominant over white flowers (f), crossing a heterozygous purple-flowered pea plant and a flowering pea plant can produce a likely offspring of 50% white-flowered plants.
The cross can be represented by a Punnett square:
Ff X ff
Alleles F f
f Ff ff
f Ff ff
In the offspring can then be observed:
Purple-flowered pea plants, heterozygous (Ff) 50%. White-flowered pea plants (ff) 50% (ff) 50% (ff) 50% (ff)According to this, the prediction for an Ff X ff cross in pea plants is a 50% probability of white-flowered offspring.
2. In incomplete dominance it can be observed that heterozygous individuals show a mixture of the traits of both parents, without the predominance of one allele over the other being evident. In this case, pure dominant individuals are different from heterozygotes.
A snapdragon plant can have red and white flowers. As this is an incomplete dominance, the pink color of the flowers is a mixture of the phenotypes of red-flowered and white-flowered plants.

Which of the following is not a negative consequence of using pesticides
A) can be harmful to other beneficial plants and insects
B) promotes resustance over time
C) leads to pollution
D) leads to better crop yield
Answer:
Something that is not a negative consequence of using pesticides is that it leads to better crop yield.
Explanation:
Pesticides are chemicals that are specially designed to protect the plants from pests, mostly from insects. Their usage has been constantly increasing around the globe, and they are the most used where there is commercial agriculture. Pesticides, unfortunately, lead to a lot of problems, mainly pollution and loss of biodiversity.
Something that is a positive from the usage of pesticides though is the fact that it leads to better crop yield. By protecting the plants from pests, the plants can grow without any problem, not spending energy for fighting the damage of the pests, and generally not being damaged. All of this leads to higher production of crops and better crop yields in general, and that is very useful in a world where there is more and more demand for food.
Answer:
d leads to better crop yield.
