What is is called when a doctor removes both an ovarian cyst and the affected ovary?

The appropriate word to fill into the blank would be accessory.

In the Fall of the year, leaves appear red, orange, yellow, and brown because the chlorophyll decreases in the leaves and allows the accessory pigments to reflect mostly colors other than green.

The core pigment in leaves that makes them appear green is chlorophyll. The pigment is primarily responsible for absorbing light energy to drive the photosynthetic process in plants.

Some other pigments, also known as accessory pigments such as carotenoids, anthocyanins, xanthophylls, etc., help out chlorophyll in some ways but have colours that are different from green.

Thus, the appearance of other colours such as orange, yellow, brown, etc., on leaves is due to a decrease in chlorophyll and the reflection of the colours of the accessory pigments.

In the gel electrophoresis lab, you determined the genotype of three different DNA samples.

Gel electrophoresis is a process that allows you to separate fragments of DNA based on size. You place different size fragments of DNA into a gel, then apply current to the buffer surrounding the gel, the DNA will travel through the gel but move at different speeds based on the different fragment sizes. Larger fragments of DNA will move slower than smaller fragment sizes.

Let consider two different alleles:

The bigger allele happens to contain a restriction site that is allowed to be cleaved by a restriction enzyme while the smaller allele has a mutation in the restriction site that means that it will not be recognized and cleaved by that same restriction enzyme.

Let us remember that the person will have two copies of this gene and can be:

An individual with h0m0zyg0us AA only have versions of the gene that will be cut by the restriction enzymes, each allele producing a small fragment of DNA and a medium-size fragment of DNA

An individual with the genotype aa only has the version of the gene that does not have the restriction site and therefore does not get cut by the restriction enzyme. The DNA sample from this individual will have a single larger fragment of DNA.

When you isolate DNA from heterozygous Aa, half of the DNA isolated has the allele with the restriction site that gets cut into two fragments while the other half will have the allele that does not have the restriction site and remains whole when a restriction enzyme is added.

Therefore, we can conclude that in the gel electrophoresis lab, you determined the genotype of three different DNA samples.

Explanation:

A red onion cell placed in a saline solution will lose water when water moves from the cell to the surrounding hypertonic medium via osmosis, causing the cell to shrivel up.

The passage of solvent molecules from a lower concentration solution to a higher concentration solution across a semipermeable membrane. It is a passive process that occurs without the use of any energy.

Solvent molecule transfer proceeds from low to high concentration regions until the concentrations on both sides of the membrane are equal.

Thus, we can conclude that when a red onion cell is placed in salt water.

As we can see in the diagram the onion cell shrink which means it is placed in salt water which is a hypertonic solution.

An environmental factor such as storms and extreme heat or cold that affects population regardless of their density are known as density- independent factors.

Density- independent factors are type of limitation factors that affects the population size in specific environment regardless of the density of that population.

Explanation:

Arteries typically carry oxygenated blood, which is bright red in colour. The exception is the pulmonary artery which carries deoxygenated blood from the heart to the lungs.

Answer:

Venules carry deoxygenated blood. All blood in humans is bright red when oxygenated, but, a darker red when deoxygenated. Deoxygenated blood is darker due to the difference in shape of the red blood cell when oxygen binds to haemoglobin in the blood cell (oxygenated) versus does not bind to it (deoxygenated).

Explanation:

Conditions necessary for germination are :

Temperature/Warmth

Oxygen/Air

Water/Moisture

Answer:

The oxygen molecule enters the human body from the mouth or nose and reaches the phraynx and then the larynx, trachea and the bronchus. It then enters the lungs which then the red blood cells takes the oxygen from the blood and carries it to the muscle in the arm.

The pathway of an oxygen molecule from the air outside your body to a muscle cell in your arm involves several sequential steps, including inhalation, gas exchange in the lungs, transportation through the bloodstream, and diffusion into muscle cells.

During inhalation, you breathe in air through your nose or mouth. The air travels through your respiratory system, passing through the trachea (windpipe) and into the bronchi, which branch into smaller tubes called bronchioles. Eventually, the inhaled air reaches the alveoli, tiny air sacs located at the end of the bronchioles in the lungs.

In the alveoli, oxygen molecules diffuse across the thin walls of the air sacs and into the surrounding capillaries. Oxygen diffuses from an area of higher partial pressure (in the alveoli) to an area of lower partial pressure (in the capillaries). Hemoglobin, a protein within red blood cells, binds to the oxygen molecules in the capillaries, forming oxyhemoglobin.

Answer:

The citric acid or Krebs cycle processes in the matrix of mitochondria produce a molecule called NADH. NADH is then converted to adenosine triphosphate by enzymes buried in the mitochondrial inner membrane (ATP). Energy is stored in the form of chemical bonds in ATP.

Explanation:

Oxidative phosphorylation produces the majority of the ATP produced by aerobic cellular respiration. By pumping protons across a membrane, the energy released by the O2 is utilized to create a chemiosmotic potential. This potential is subsequently used to activate ATP synthase, which converts ADP and phosphate groups into ATP.

Mitochondria (plural: mitochondrion) are membrane-bound cell organelles that provide the majority of the chemical energy required to fuel the cell's metabolic activities. Adenosine triphosphate is a tiny molecule that stores chemical energy created by mitochondria (ATP).

The energy currency of the cell is ATP, or adenosine triphosphate. It retains the energy created during cellular respiration when glucose is oxidized. Energy is stored in the form of high-energy phosphate bonds, which are broken to release energy. Energy is released when ATP is broken down into ADP and Pi.

Paleontologists can determine the age of fossils using methods like radiometric dating and categorize them to determine the evolutionary relationships between organisms

The preserved remnants or traces of extinct animals, plants, and other organisms are known as fossils. Because they demonstrate that earlier life on Earth was distinct from the life observed today, fossils are crucial pieces of evidence for evolution.

According to the idea of evolution, modern life forms have evolved from more ancient ones.

The original theory suggested that this occurred slowly and gradually, but fossil evidence suggests that the process occasionally went wrong and engaged in some very bizarre experiments.

Answer:DNA is double stranded and cannot fit through the nuclear membrane; RNA is single stranded.

Explanation:

DNA is double stranded and cannot fit through the nuclear membrane; RNA is single stranded.  DNA could get damaged because of the osmotic nature of cytoplasm. Therefore, option (C) is correct to mitigate he damage.

The proteins are produced by cells by the transcription and translation of certain genes from their DNA into molecules of messenger RNA (mRNA), chains of amino acids, and finally fully functioning proteins.

The DNA would need to go to the cytoplasm in order to directly make proteins. Because of the osmotic properties of cytoplasm, DNA may become damaged during the translocation process. The cellular machinery does not directly make proteins from DNA in order to reduce the harm.
