Verdadero o falso mediante el genotipo podemos determinar si existen dominancia en una característica
Answer:
Verdadero
Explanation:
Sabemos que los caracteres dependen de los genes. Y los genes pueden presentarse en forma de alelos dominantes, o alelos recesivos. La expresión de los alelos recesivos son enmascarados o escondidos por el alelo dominante. Es decir, que si ambos alelos se encuentran juntos en un heterocigota, solo el alelo dominante se expresará.
Entonces el alelo dominante expresa la característica que resulta dominante, mientras que el alelo recesivo expresa la característica recesiva.
Genotipo:
Homocigota dominante ----> Expresa caracter dominante (Solo el alelo dominante esta presente)Heterocigota -------------------> Expresa el caracter dominante (Ambos alelos estan presentes, pero el dominante es quien se expresa)Homocigota recesivo --------> Expresa el caracter recesivo (solo alelos recesivos estan presentes)Por ejemplo, si tenemos dos fenotipos rojo y amarillo, y sabemos que el color esta codificado por un gen dialelico llamado M. También supongamos que no sabemos qué alelo expresa qué color. Teniendo solo estos datos, no podemos decir si el rojo es el color dominante o si el amarillo lo es.
Sin embargo, si tenemos los siguientes genotipos acompañando esta información:
MM--> AmarilloMm--> Amarillomm --> RojoRecién ahora podemos deducir que el caracter dominante es el amarillo.

What is it called when one organism imitates the features or behavior of another?
Answer:
Mimicry
Explanation:
Mimicry is an evolved similarity ( in traits and behaviors ) , often between two organisms
An example of mimicry is the resemblance between coral snakes and kingsnakes. A kingsnake is a harmless snake whereas a coral snake is a fairly venomous snake. A kingsnake looks similar to a coral snake ( mimics its features) leading to kingsnake predators often intimidated by the kingsnakes appearance, because like stated before coral snakes are venomous and kingsnakes mimic their features.
Answer:
Mimicry is the similarity of one organism (the mimic) to another (the model) that enhances the mimic's fitness through its effect on the behavior of a third party, the operator.
Explanation:
a close and long-term biological interaction between two different biological organisms, be it mutualistic, commensalistic, or parasitic.

A. Lack of decomposers
B. A balanced water table
C. Variety of organisms
D. A narrow temperature range
Answer:A
Explanation:
A variety of organisms contributes most to promoting sustainability in an ecosystem. Hence, option C is correct.
What is an ecosystem?An ecosystem is a region where a bubble of life is created by plants, animals, and other organisms interacting with the weather, environment, and other factors. Abiotic variables, or nonliving components, coexist with biotic components in ecosystems.
Based on their overall environments, ecosystems can be divided into three basic categories: freshwater, marine, and terrestrial. Individual ecosystem types based on the environmental habitat and creatures present can be found within these three categories.
A variety of organisms contributes most to promoting sustainability in an ecosystem. Hence, option C is correct.

Explanation:
Cell division is not only for generating copy of DNA . Why ?
Answer:
sorry don't know sorry
Explanation:
ok
Answer: During every cell division, a cell must duplicate its chromosomal DNA through a process called DNA replication. The duplicated DNA is then segregated into two "daughter" cells that inherit the same genetic information. ... Healthy cells can perform DNA replication with almost absolute accuracy most of the time.

Structure of plant cell
Answer:
A cell wall, a broad central vacuole, and plastids such as chloroplasts are all present in plant cells. The cell wall is a dense layer that covers the cell and provides structural support and protection. It is located outside the cell membrane. The turgor pressure against the cell wall is maintained by the central vacuole.

What type of weather does a H pressure system bring to an area? *
O wet and cloudy
O Dry and cloudy
O clear skies and sunny
O Hot and Sunny
✧･ﾟ: *✧･ﾟ:* *:･ﾟ✧*:･ﾟ✧
✅ Clear skies and Sunny.Explanation: ❗ Cold air is denser and thicker than warm air, so it usually sinks as warm air increases. Cold air sinks which causes a transient accumulation of water near the earth's area and thus an area with a high pressure in regions where winds meet at high altitude. With an increase in altitude air pressure reduces, so high pressure is in fact a relative concept. Weather forecasters commonly use this to signify high pressure relative to normal atmospheric pressures at that level.

Explain what would happen to a person if they eat/drink something that their body does not have an Enzyme for?
Answer:
People with lactose intolerance may have a variety of symptoms. It all depends on how much dairy or how many milk-containing foods the person eats and how little lactase the body produces.
Usually within 30 minutes to 2 hours after eating, someone with lactose intolerance will experience nausea, stomach cramps, bloating, gas, and diarrhea. This can be unpleasant, not to mention embarrassing if you're at school or out with friends.
Because many people may think they're lactose intolerant when they really aren't, it helps to see a doctor who can diagnose the condition correctly and advise you on ways to manage it.

What is karotyping and how is it used in science / medical field??
Answer:
Karotyping is a chromosomal analysis. It can be used to look for diseases caused by irregularities in the chromosomes, such as Down syndrome.
Explanation:
Karotyping is a chromosomal analysis of the chromosomal constitution of the nucleus of a cell, which is equal to the complete chromosomal makeup of a person. The chromosomes of each species have a certain structure both in size, shape and their own band when they are stained in the laboratory. This allows them to be identified as well as to know if all the genetic information is in the correct order. In addition to numerical abnormalities in chromosomes, structural alterations mean that certain chromosomal regions can be duplicated or even absent. This gain or loss of genetic material has highly varied consequences depending on the genes involved. Another type of structural alterations are translocations and inversions. The karyotype can be studied in search of diseases caused by irregularities in the chromosomes, such as Down syndrome. It also helps to identify problems that a baby conceived through assisted reproduction may have when it is born, by extracting the karyotype that is found in the amniotic fluid of the embryo.
