When a substance changes from a gas into a liquid due to a change in temperature, melting occurs, which is a physical change.


When a substance changes from a solid into a liquid due to an increase in temperature, it is a physical change.


When a substance changes from a gas into a liquid due to a decrease in temperature, the substance cools down and condenses, which is a phase change.


When a substance changes from a liquid into a gas due to a decrease in temperature, the substance evaporates and cools down, which is a phase change.

Answer:

As DNA replication continues and the replication bubble expands, the parental double helix is unwound and separated into its two component strands. This unwinding and separating of the DNA require three different types of proteins: helicase, topoisomerase, and single-strand binding proteins.

d. mitochondria --> Where respiration reactions happen

Answer:

Explanation:

The Sun's magnetic field goes through a cycle, called the solar cycle. Every 11 years or so, the Sun's magnetic field completely flips. This means that the Sun's north and south poles switch places. Then it takes about another 11 years for the Sun's north and south poles to flip back again.

The best way to get the exact preach tree is through Asexual reproduction.

Asexual reproduction is the only method of reproduction in which the exact copies of genes in the parents are transferred to the offspring.  If  cross pollinations( Sexual reproduction') with the a peaches plants from a different parents plants takes place, genetic variation at meiosis will not permit the inheritance of the exact copies of genes for diseases resistance.

Therefore, it is ideal in this scenario to by pass crossing over and recombination at meiosis, in order get the exact copes of genes for disease resistance through mitosis in the offspring, asexual preproduction is used.

The method that would produce peaches of exactly the same characteristics would be cloning or vegetative propagation.

Cloning the peaches that are more resistant to disease will result in the production of peaches with exactly the same morphological and genetic attributes.

The same result would be obtained by propagating the desired peaches asexually using relevant means.

Answer:

- ​Cancer isn't a single disease. The term cancer encompasses more than 200 diseases all characterized by the uncontrolled proliferation of cells.

- Cancer cells also fail to undergo programmed cell death, or apoptosis, under conditions when normal cells would (e.g., due to DNA damage). In addition, emerging research shows that cancer cells may undergo metabolic changes that support increased cell growth and division 5start superscript, 5, end superscript.

Genetic Changes and Cancer

Genes carry the instructions to make proteins, which do much of the work in our cells. Certain gene changes can cause cells to evade normal growth controls and become cancer. For example, some cancer-causing gene changes increase production of a protein that makes cells grow.

- People who have certain jobs such as; painting, construction, pesticide and petroleum workers have an increased risk of cancer. Many studies have shown that exposure to asbestos, benzene, benzidine, cadmium, nickel, arsenic, radon and vinyl chloride in the workplace can cause cancer.

- Metastatic cancer causes most cancer deaths, but exactly why it is so difficult to treat is not precisely understood. Metastatic tumors often acquire additional genetic changes from those in the primary tumors that spawned them, and these genetic characteristics may cause them to resist standard treatments.

- Treating cancer is further complicated due to the lifestyle and attitude of patients, the different physiology of people and the rate their bodies will metabolise drugs, the blood supply to the tumour affecting the drug getting into the tumour, the tumour physiology and the fact that the tumour can continue to change.

- The stage of a cancer describes the size of a tumour and how far it has spread from where it originated. The grade describes the appearance of the cancerous cells.

- Cancer treatment options include:

Surgery. The goal of surgery is to remove the cancer or as much of the cancer as possible.

   Chemotherapy. Chemotherapy uses drugs to kill cancer cells.

   Radiation therapy. ...

   Bone marrow transplant. ...

   Immunotherapy. ...

   Hormone therapy. ...

MY INTRODUCTION ARE ANSWERS TO ALL YOUR QUESTIONS (your question is too long)

Answer:

20 centimeters apart.

Explanation:

Tanya planted seedlings in her garden over the weekend.  The instructions that came with the seedlings stated that they need to be planted 0.2 meters apart.  Tanya has a measuring tape that has values in centimeters.  As we know 1 meter = 100 centimeters . Therefore, 0.2 meter = 0.2 × 100 = 20 centimeters. So Tanya need to be planted 20 centimeters apart.

Explanation:

those gases dissolve with water vapor in the air to form H2SO4 and HNO3

When it rains, these acids dissolve into rainwater and makes the pH of the rainwwater decreases

Viral infections cause similar symptoms as bacterial infections. Antibiotics treat bacterial infections but do not treat viral infections. Some antiviral medicines are used to treat viral infections.

The misuse of antibiotics to treat a viral infection contributes to antibiotic resistance.

Antibiotics kill bacteria without damaging the body’s cells. They do so by interfering with how bacteria live and reproduce. Normal body cells work in different ways, so they’re not affected.

While antibiotics are effective in treating bacterial infections, they can also damage the immune system when used incorrectly or too frequently. Therefore, the doctor should prescribe antibiotics only when needed and sparingly.

Answer:

Smaller single-celled organisms have a high surface area to volume ratio, which allows them to rely on oxygen and material diffusing into the cell (and wastes diffusing out) in order to survive. The higher the surface area to volume ratio they have, the more effective this process can be.

Answer:

THIS ARE MONOCOT PLANTS EXAMPLES:

Legumes (pea, beans, lentils, peanuts) daisies, mint, lettuce, tomato and oak are examples of dicots. Grains, (wheat, corn, rice, millet) lilies, daffodils, sugarcane, banana, palm, ginger, onions, bamboo, sugar, cone, palm tree, banana tree, and grass are examples of plants that are monocots

THIS ARE DICOTS PLANTS EXAMPLES:

Common examples of dicots include fruits like grapes and apples, trees like chestnut and oak, vegetables like soybean and carrot, and flowers like rose and hollyhock. Dicots differ from monocots (having just one cotyledon) in the seed, vascular structure, flowering, and leaf arrangement.

A change in the gene's DNA sequence can lead to a change in the protein's amino acid sequence.

The sequence of a protein is determined by the DNA of the gene that encodes that protein (or that encodes a portion of the protein, for multi-subunit proteins).

A change in the gene's DNA sequence can lead to a change in the protein's amino acid sequence.

Even changing just one amino acid in the protein sequence can affect the protein's overall structure and function. For example, a single amino acid change is associated with sickle cell anemia, an inherited disease that affects red blood cells.
