Answer:

An important term in genetics that was not used by Mendel was the word "gene", a particle of the chromosome responsible for the traits of a living being. The molecule discovered by Oswald Avery - related to genes and inheritance - was DNA, a discovery he made in 1944.

Explanation:

Despite being considered the father of genetics and providing important information about the inheritance of traits, Mendel did not go so far as to use the term "gene," which is where the alleles responsible for those traits reside. The term "gene" was first used by another botanist, Wilhelm Johanssen, who in 1909 proposed the use of the word gene as the name of the particle responsible for inheritance.

In 1944, the Canadian physician Oswald Avery, faced with the mistaken belief that genes were found in proteins, proposed an experiment where he discovered that the molecule responsible for heredity was deoxyribonucleic acid, or DNA.

Answer:

B.Strong hydrogen bonds

Explanation:

The deoxyribonucleic acid (DNA) molecule consists of two chains or strands of nucleotides that are held together in a double helix by hydrogen bonds between the bases of the nucleotides.

Answer:

Explanation:

Datos disponibles:

Podríamos establecer que M es el alelo dominante, mientras que m es el alelo recesivo.

A partir de la información brindada, podríamos suponer que:

Opción 1:

La miopia es un caracter expresado por un gen dominante. Si este fuera el caso, entonces al menos uno de los padres debería tener miopia para poder heredarle al hijo el alelo dominante para expresar el caracter. Si este fuera el caso, los posibles genotipos de los padres serían:

Parental)  Mm   x   mm (al menos uno de los padres con miopia)

F1) 1/2 Mm (Hijo miope)

    1/2 mm (Hijo con visión normal)

Pero en este caso, los dos padres tienen visión normal, entonces si el gen dominante expresa la miopia, los genotipos de los padres serian homocigotas recesivos, mm. Si ambos padres son homocigotas recesivos, no podrían heredarle a ningun hijo el alelo de la miopia. En este caso, la cruza sería:

Parental) mm    x    mm

F1) 100% mm (todos los hijos con visión normal)

Sin embargo, para el ejemplo planteado, los dos padres tienen visión normal, uno de los hijos tiene visión normal y el otro tiene miopia, lo que nos conduce a la segunda opción.

Opción 2:

La miopia es un caracter heredado por un gen recesivo, m. Mientras que la visión normal es heredada por un gen dominante, M. Entonces, si este fuera el caso, para que ambos padres con visión normal, tengan un hijo homocigota recesivo para el caracter, entonces ambos padres deberian ser heterocigotos. Su hijo miope heredaría un alelo recesivo de cada padre y expresaría el defecto. El genotipo de las personas con miopía sería entonces homocigota recesivo. Esta cruza sería de la siguiente manera:

Parental) Mm    x    Mm  (Ambos padres heterocigotas)

Gametos) M   m     M     m

Cuadro de Punnet)

                M             m

     M       MM         Mm

     m       Mm         mm

F1) 3/4 o 75% de probabilidad de tener un hijo con visión normal

    1/4 o 25% de probabilidades de tener un hijo miope.

Entonces, podemos concluir que:

Answer:

diffusion

Explanation:

it puts it out and reduces it

Answer:

Explanation: This process is called mitosis. However, parental gametes – the sperm and egg cells – are unique from all other cells in that they reproduce through a process called meiosis.  The purpose of meiosis is to shuffle genetic information and cut the cellular chromosome number in half, from 46 chromosomes to 23 chromosomes.  In this way, when an egg and sperm cell combine during fertilization, the resulting embryo will inherit the appropriate amount of unique genetic information from each parent.tion:

Climate - long cold winters, with annual temperatures mostly below freezing.

Soil - the soil is covered in ice throughout the year.

Plants - hundreds of species of moss, algae and lichen survive the harsh conditions of the Polar biome.

Gene expression has been defined as the process where the genes produce proteins and RNA. They determine the traits in offspring as various types of proteins pass from parent to offspring.

Gene expressions are said to be the expression of the genome products in the cell that undergoes the process of transcription and translation to produce the RNA and protein structures that are responsible for providing the phenotype and genotype.

The genes code for the RNA and protein that regulates the amount and type of proteins to be expressed in the offspring that are passed from a parent through reproduction methods. They are hereditary patterns that vary in some amount to make two individuals different from each other.

Therefore, gene expression plays an important role in determining the trait in offspring.

Chromatin

Explanation:

Chromatin means "chroma" in Greek. It can be found in eukaryotic cells with non-dividing nucleus. They make up the chromosomes of cells during cell division. The fibers of chromatin consists of DNA (deoxyribonucleic acid) and proteins (histones and non-histones).

It is said that chromatins got their name owing to their bright colors when mixed with dye. This was found by scientists who inspected it under a microscope.

Vision problems. Heart attack. Stroke.

Explanation:

Answer:

Many things.

Explanation:

Blood pressure is a needed thing in a body. It gets blood to your organs and everywhere that needs it. If it didn't work, many things could happen.

Too high BP(hypertension):

If your blood pressure is too high, it can cause ruptured vessels, heart attacks, strokes, heart failure, which is where the heart enlarges too much to continue pumping blood at the adequate pressure/speed, kidney disease/failure, which would be from damage to the arteries around the kidneys, vision loss due to damage to the vessels in the eyes, angina, which is chest pain due to narrowed vessels in the chest, some forms of which may cause heart attacks.

Too low BP(hypotension):

If you're experiencing hypotension, there are many things commonly associated with it. These are dizziness, fainting, nausea, blurred/fading vision, lack of focus, and fatigue. If hypotension becomes extreme, it can cause someone to go into shock, which is life threatening and can and will cause death.

Answer:

Simply put your hand out and block them and put them back in the corner in a sit position. make sure that you let your dog know that not moving is what gets them. The reward gradually increase the distance and time as we did in the corner until they can stay for 10 seconds at 10 feet away.

Also, with a leash, when teaching your dog to stay, say "stay" and pull the leash back to when the dog is sitting. This gives the dog an understanding of what to do and how to do it. Repeat this a few times. Then the dog will learn to sit and stay before the leash stops. Then they will have learned the "Stay" command.

Answer:

Positive reinforcement is one of the best ways to train a dog. This may be treats, such as a biscuit, or affection, like a belly rub. There's also giving them a new toy, or taking them on a walk even. Most trainers have these tools called clickers. They get a dog's attention and keep it, refocusing them if they wander off mentally.

Not all trainers train their dogs to stay the same way. More popular ones may give the command "Sit!", which sometimes isn't very effective. I personally trained my dogs with a type of sign language. One finger up for "sit", and two for "stay". Full hand is "down" or "wait". As I said, many different ways of training.

If a dog does not respond to positive reinforcement, there is negative reinforcement, but it is seriously frowned upon. This could be a water bottle or receiving no treats. Some people take this too far, however.

The best way to train a dog to stay is to be patient with them, use positive reinforcement, and to understand. They're a dog, they're bound to be distracted, just like a child. To refocus them, snap your fingers or whistle, and if need be, call their name. Don't expect them to learn it all in one day: all dogs have different personalities and learning capabilities. One dog may pick it up quick, while it may take another month to learn, just like humans.

You also have to take into consideration age and history of the dog. These are two very important factors in training, as if a dog is used to being spoiled rotten, positive reinforcement most likely won't help. If the dog is a young puppy, they're going to want to learn and explore instead.
