D) human activity
Answer:
human activities ......Ruby has observed that plants in her garden vary in height. She wants to investigate whether a plant species (species A) grows faster than the other garden species (species B, C, and D). Select the statement that describes Ruby gathering enough evidence to support a scientific explanation concerning plant growth rates
Answer:
This question lacks options, the options are:
A) Ruby measures the heights of several species A, B, C, and D plants for a week under different conditions and finds a journal article that describes the growth rate of species A.
B) Ruby measures the height of a species A plant for a week and finds an anonymous gardening blog that describes the growth rate of species A.
C) Ruby measures the heights of several species A, B, C, and D plants for a week under the same conditions.
D) Ruby measures the heights of several species A, B, C, and D plants for a week under the same conditions and finds journal articles that describe the growth rates of each species.
The answer is D
Explanation:
According to this question, Ruby wants to investigate whether a plant species A in her garden grows faster than other plant species (B, C and D) due to the varying height she observed in them. To do this, Ruby will need to conduct a scientific investigation by measuring the height of all the plant species she is trying to compare (A, B, C, D).
However, she must do the measurements under the same conditions i.e. controlled in order not to influence the result. In order to make a scientific explanation concerning the plant growth rates, Ruby should find journal articles that describe the growth rates of each species and make comparison with her experimental/measured height values.

Answer:
Motor neurons are activated and the muscles of your arm contract, moving your hand away from the sharp object. This occurs in a fraction of a second — before the signal has been relayed on to the brain — so you will have pulled your arm away before even becoming conscious of the pain.
This is called a motor reflex.

La miopia es un caracter bastante comun en la especie humana. Un matrimonio en el que ambos conyugues poseen vision normal, tienen dos hijos, uni con una vision normal y el otro con miopia. Teniendi en cuenta el fenotipo de todos los miembros de la familia ¿quenpodrias deducir del gen que controla la miopia? ¿ que genotipo podrias asignsr a cada individuo?
Answer:
El gen que controla la miopia es dialelico, autosómicoEl alelo dominante M expresa visión normal, El alelo recesivo m expresa miopia, Los padres con visión normal serían heterocigotas, Mm.Tendrían un hijo con visión normal homocigota dominante MM o Heterocigota Mm Tendrían otro hijo homocigota recesivo con miopia, mm.Explanation:
Datos disponibles:
Ambos padres poseen visión normalUno de los hijos tiene visión normalEl otro hijo tiene miopiaPodríamos 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:
El gen que controla la miopia es dialelico, autosómicoEl alelo dominante M expresa visión normal, El alelo recesivo m expresa miopia, Los padres con visión normal serían heterocigotas, Mm.Tendrían un hijo con visión normal homocigota dominante MM o Heterocigota Mm Tendrían otro hijo homocigota recesivo con miopia, mm.If a strand of DNA has 20% C, what percent will be G?

Mr. Rojas, a biology teacher, asks his class to evaluate two examples of changes to a pond ecosystem. The table summarizes the examples. Example 1 Example 2 Original pond community algae, cattails, a variety of fishes, ducks, raccoons algae, cattails, a variety of fishes, ducks, raccoons Change to the ecosystem increase in nitrogen and phosphorus content of the water, due to agricultural runoff decrease in the duck population, due to hunting by humans Result after one year an algal bloom that covers the surface of the pond, followed by a decrease in all animal populations Little or no effect; duck population returns to previous levels after one year Based on the results shown in the table, Mr. Rojas's class can evaluate which property of the pond ecosystem?
Answer: the resilience of the pond ecosystem to different types of changes
Explanation:
The property of the of the pond ecosystem that Rojas's class can evaluate is ;
The Resilience of the ecosystem ( pond )
Given the various changes faced by the pond ecosystem and the response to the varying changes the property that the students should most likely study/evaluate is the Resilience level of the pond ecosystem to the changes.
Resilience is the ability of a substance or system to respond/recover positively from negative changes or disturbances faced by the system just like the pond ecosystem
In conclusion The property of the of the pond ecosystem that Rojas's class can evaluate is ; The Resilience of the ecosystem ( pond ).

Meiosis is a process of Cell division in which the number of chromosomes per cell is cut in __________ and homologous chromosomes in a ___________ cell are separated. Meiosis involves two distinct stages: meiosis I and ___________. One diploid (full # of chromosomes) cell becomes ____haploid (half # of chromosomes) daughter cells.
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:

Why don't we all look the same if all humans have the same number of chromosomes
that contain the same genes?
Answer:
A small number of genes are slightly different in everyone which results in everyone looking different from one another. Each person has two copies of each gene, one from your mother and father which makes you look somewhat alike. Their are alleles that have small differences in them which are different from someone elses DNA bases which make you look different.

How do you train your dog to stay? Include details and be specific
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.
Hope this Helps!
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.
