How did the Industrial Revolution contribute to global climate change?
A. It led to an increased use of alternative fuels other than fossil fuels.
B. It led to an increased use of coal, oil, and other fossil fuels.
C. It led to the release of chemicals that destroyed the ozone layer.
D. It led to the development of nonrenewable sources of energy. (I think it's B. Please correct me if I'm wrong.)
Answer: You're right its b.
Explanation:
Human activity has rapidly increased the emission of greenhouse gases to the atmosphere. Since the start of the Industrial Revolution, in about 1750, human activities such as burning fossil fuels, including coal and oil, have increased greenhouse gas concentrations in our atmosphere.

A. John thinks that a special juice will increase the productivity of workers. He creates two groups of 50 workers each and assigns each group the same task (in this case, they're supposed to staple a set of papers). Group A is given the special juice to drink while they work. Group B is not given the special juice. After an hour, John counts how many stacks of papers each group has made. Group A made 1,587 stacks, Group B made 2,113 stacks.
B. Candy notices that her shower is covered in a strange green slime. Her friend Belinda tells her that coconut juice will get rid of the green slime. Candy decides to check this out by spraying half of the shower with coconut juice. She sprays the other half of the shower with water. After 3 days of "treatment" there is no change in the appearance of the green slime on either side of the shower.
C. Elisa is working on a science project. Her task is to answer the question: "Does Grow Long (which is a commercial hair product) affect the speed of hair growth?" Her family is willing to volunteer for the experiment.
Answer:

Answer:
Picture B,
Explanation:
where nuclear membranes form around each set of chromosomes resulting in two nuclei.
The correct option is B. Picture B, where nuclear membranes form around each set of chromosomes resulting in two nuclei.
What is telophase?The last phase of cell division is known as telophase. The nuclear envelopes reform around the fresh nuclei in either half of the dividing cell during telophase.
The nucleus' ribosome-producing regions, or nucleolus, are back. The major components of the spindle apparatus begin to depolymerize as soon as the cell has finished transporting the chromosomes.
The chromosomes dissociate from their tightly bonded structure and return to free chromatin as telophase nears completion. Telophase is terminated by cytokinesis, a process that divides the cell into two new cells.
Therefore, The correct option is B. Picture B, where nuclear membranes form around each set of chromosomes resulting in two nuclei.

Seed Germination Investigation
The students are to investigate the process of seed germination during their summer
vacation.
They will select different types of seeds, such as beans, peas, or sunflower seeds.
Encourage students to set up a germination experiment by placing the seeds in
different conditions, such as light vs. dark, or wet vs. dry. Moreover, they need to
pot the same seed in more than one pots.
They should observe and document the changes that occur over time, including the
emergence of roots and shoots.
Answer:
Okay...In this case I suggest you use corn seed or beans seed
Explanation:
It should take about 6 weeks to see the Germination, until then continue watering it and giving it sunlight
The seed germination investigation during the students' summer vacation involves selecting various seeds (e.g., beans, peas, sunflower) and setting up an experiment. They will place the seeds in different conditions, like light vs. dark or wet vs. dry, and pot the same seed in multiple pots. Throughout the investigation, the students are expected to carefully observe and document the changes that take place over time, including the growth of roots and shoots. This hands-on approach allows them to gain practical knowledge of seed germination and develop essential scientific skills in observation, data collection, and documentation.

Answer: 4
Explanation:
1. A genetic mutation causes a disease when the the DNA encodes is altered
such that it no longer functions properly.
2 Errors during __ _ can cause genetic problems with the resulting germ cells.
3. Down syndrome is caused by three copies of chromosome 21, also known as
21.
4. A silent mutation is a change in the DNA that does not change the encoded
and has no phenotypic effect.
Answer:
protein
meiosis
trisomy
amino acid or stop codon
Diagnosing genetic conditions can be difficult because, although scientists have identified genes related to specific diseases, often not enough is known about the disease to determine the exact role of a given gene in the disease. In other cases, perhaps no mutation exists on a known gene for a condition, but a mutation occurs on a related gene that also gives rise to the condition. The human genome is vast, with about 24,000 genes. Scientists do not yet understand the roles and interactions of all these genes in human health and disease.
Meiosis is the process by which germ cells—egg cells in females and sperm cells in males—develop. Meiosis causes germ cells to obtain only half the chromosomes of the person. If the chromosomes fail to separate properly and are shuffled improperly into the chromosomes, an egg cell or sperm cell can have either too few or too many chromosomes. Trisomy 21, or Down syndrome, is a developmental disorder in which three copies of chromosome 21 are passed down from the person's mother and father. The word "trisomy" means that there are three copies of chromosome 21, indicating that one of the germ cells did not undergo meiosis properly. This condition affects about 5,000 babies born each year.
In a silent mutation, one nucleotide base in a protein-coding region gets swapped out for another base. However, the resulting three-nucleotide sequence, or codon, encodes for the same amino acid.
Explanation:
Penn Foster :)
Protein, meiosis, trisomy, amino acid, or stop codon leads to genetic changes.
What is a genetic mutation?Meiosis is the process by which male and female germ cells—egg and sperm cells, respectively—develop. Germ cells only get half of the person's chromosomes during meiosis.
An egg cell or sperm cell may have either too few or too many chromosomes if the chromosomes fail to split correctly and are shuffled wrongly into the chromosomes.
Down syndrome, also known as trisomy 21, is a developmental disease when three copies of chromosome 21 are inherited from the mother and father. When chromosome 21 is found in three copies, this suggests that one of the germ cells did not go through meiosis properly.
Therefore mutation leads to trisomy, change in meiosis, and silent mutation is due to amino acid.

Answer:
H - 16
C - 4
O - 4
Explanation:
The reaction is
2CO + 4H2 = x CH4O
This means x=2 because the number of atoms have to be balanced. There are 8 Hydrogens on one side, meaning 16 in all. There are 2 Carbons on one side, meaning 4 in all. Lastly, there are also 2 Oxygens on one side, meaning there are 4 in all.
Atoms in the reaction are H- 8 atoms, C-2 atoms, and O- 2 atoms.
During the reaction, 2 molecules of methanol are produced.
We can write the equation as
CO+ 2 H2 ⇒ CH3OH
(Methanol)
For 1 molecule of CO and 2 molecules of H2 we get 1 molecule of CH3OH.
Hence, for 2 molecules of CO and 4 molecules of H2 we get 2 molecules of CH3OH(methanol).
From the reaction, we can easily calculate that 8 H atoms, 2 C atoms and 2 O atoms are getting reacted.
