Answer:
D. The glass.
Explanation:
Sound travels fastest through solids. This is because molecules in a solid medium are much closer together than those in a liquid or gas, allowing sound waves to travel more quickly through it.

A scientist is treating rice plants with a chemical that causes mutations. What is the possible benefit of this treatment? A. clones B. transgenic plants C. increased genetic variation D. increased hybridization
Answer:
Explanation:
Its either B or C, look closely at the question and at the answers, you can narrow it down from then.
A scientist is treating rice plants with a chemical that causes mutations. The possible benefit of this treatment is transgenic plants. Hence, the correct option is B.
What is mutation?A mutation is a change in the DNA sequence that makes up a gene. It can result from errors in DNA replication or exposure to mutagenic agents such as chemicals or radiation, or from spontaneous changes.
Transgenic plants are the plants that have been genetically modified to express specific traits or traits that are not found in the original species. This is done by introducing foreign DNA or chemicals that change the plant's genome. This process is called genetic engineering.
Transgenic plants have become an important tool in agriculture and biotechnology, providing new opportunities for food production, environmental protection and economic growth. Hence, the correct option is B.

7.) DURING THE FIRST ERA, THE __________ ORGANISMS EVER ON EARTH WERE
ERA, THE FIRST LIVING
Answer:
The first living organism on Earth are Bacteria in the first era.
Explanation:
Bacteria are the first organism to leave be on Earth. They came into existence about 3.5 billion years in the first era in the waters of small oceans. Then there were anaerobic hetetrophic bacteria because the atmosphere was free of oxygen before. Cyanobacteria then became the first autotrophic organisms and first photosynthesizer that release oxygen to the atmosphere after photosynthesis.
Explain how bacteria can be both harmful and helpful.
The species of bacteria that colonize our respiratory and digestive systems help set up checks and balances in the immune system. White blood cells police the body, looking for infections, but they also limit the amount of bacteria that grow there. Likewise, bacteria keep white blood cells from using too much force. Bacteria also help out by doing things cells are ill-equipped to do. For instance, bacteria break down carbohydrates (sugars) and toxins, and they help us absorb the fatty acids which cells need to grow. Bacteria help protect the cells in your intestines from invading pathogens and also promote repair of damaged tissue. Most importantly, by having good bacteria in your body, bad bacteria don’t get a chance to grow and cause disease.
Some species of bacteria in your body can result in diseases, such as cancer, diabetes, cardiovascular disease, and obesity. Usually, these diseases happen only when the normal microbiome is disrupted, but that can occur even from antibiotics. Antibiotics kill bacteria, and some of those will be good bacteria that we need to protect our health. When that happens, the bad bacteria that normally are kept in check have room to grow, creating an environment ripe for disease.
Bad bacteria can exist at low levels in your body without causing harm or can grow too much and wreak havoc. Staphylococcus aureus can cause something as simple as a pimple or as serious as pneumonia or toxic shock syndrome. P. gingivalis can cause gum disease, and was recently linked to pancreatic cancer (read our article find out more). Similarly, when not suppressed by good bacteria, Klebsiella pneumonia can cause colitis, and subsequently lead to colorectal cancer.
In addition to allowing disease-causing bacteria to flourish, the elimination of good bacteria throws the immune system out of whack. The result can be simple allergies or very debilitating autoimmune diseases. Without the right balance of bacteria, your body might suffer from constant inflammation.
Inflammation is the body’s alarm system, which calls white blood cells to heal a wound or to get rid of infection. Chronic inflammation, however, can make the body more susceptible to autoimmune diseases and cancer, such as causing inflammatory bowel disease which if uncontrolled can cause colon cancer.

It is advantageous for a predator to prey exclusively on a single prey species.
Answer:
Assuming this is a true/false question, the answer would be false.
If a predator only preyed on one species, it would be at a disadvantage if the prey it feeds on gets wiped out in that region.
Therefore, your answer is False.
