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.

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.
The diagram below represents an energy pyramid constructed from data collected from an
aquatic ecosystem. Which statement best describes this ecosystem?
A.The ecosystem is most likely unstable.
B.The herbivore populations will continue to increase in size for many years.
C.Long-term stability of this ecosystem will continue.
D.The producer organisms outnumber the consumer organisms.
Energy pyramids are the models that show the flow of energy from the primary to the next level. From the energy pyramid, it can be said that long-term stability will be continued. Thus, option C is correct.
What are energy pyramids?Energy pyramids are the representation of the energy levels and the primary producers and other consumers. The producers are the base of the pyramid followed by the primary consumers.
In an aquatic ecosystem, the algae are the primary producers that provide energy to plankton and act as primary consumers. These are get eaten by small fishes and large fishes. The number of consumers gets decreased as one rises to the upper level.
Therefore, option C. an aquatic ecosystem will have stability.

Explanation:
The three things that are not displayed by food chain and food web but showed by ecological pyramid are;
Energy flowing through different ecosystems.
Amount of organisms.
Amount of energy that is being passed down.
An ecological pyramid can be regarded as graphical representation that display relationship between different organisms in an ecosystem.The trophic levels in this ecological pyramid contains amount of organisms as well as mass which is biomass and the amount of energy that can be found in each level.Therefore, it shows the energy flowing through different ecosystems.

Thinking about the process of meiosis, how do you think it is possible for gametes to end up with too many or too few chromosomes?
Through the process of meiosis, it is possible for gametes to end up with too many or too few if they fail to separate properly.
What is Meiosis?Meiosis is defined as the specialized type of cell division of germ cells in sexually-reproducing organisms that produces gametes such as sperm or egg cells. This involves two rounds of division which eventually result in four cells with only one copy of each chromosome.
This is called reduction division because the number of chromosomes in the daughter cells becomes half that of the parent cell. For example, a human cell has 46 chromosomes, but the egg and sperm cells produced as a result of meiosis have 23 chromosomes.
If chromosomes split unequally, an egg or sperm may end up with too many or too few chromosomes; when one of these participates in fertilization, the embryo may end up with too many or too few chromosomes.
Thus, through the process of meiosis, it is possible for gametes to end up with too many or too few if they fail to separate properly.

a prey population consists of individuals with a variety of running speeds. The adaption that allows some of these animals to run fast would be an example of natural selection if it helps them
Answer:
Yes.
Explanation:
Yes, the adaption that allows some of these animals to run fast will be cause of natural selection because this fast running helps them to survive and save itself from predators. The organisms adapt certain features and characteristics in order to survive in that harsh environment that leads to natural selection. Natural selection occurs by selecting the best suited organism that can survive in that specific environment so this fast speed allows the organism to survive in their environment.

4. Which of the following is NOT true of the digestive system? a. The stomach contains acids to break down food b. Digestion begins with enzymes in the stomach c. The large intestine absorbs water from the digestion of nutrients d. The small intestine does most of the absorption of nutrients
Answer:
B. Digestion begins with enzymes in the stomach
Explanation:
The digestive process starts in your mouth when you chew. Your salivary glands make saliva, a digestive juice, which moistens food so it moves more easily through your esophagus into your stomach. Saliva also has an enzyme that begins to break down starches in your food.

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.

The Punnett square for a sex-linked trait is shown. The recessive trait is carried only by the X chromosome. Xr is the recessive allele. Based on the Punnett square, which statement is true?
Xr X
X XrX XX
Y XrY XY
A.
Female offspring have a 50 percent chance of expressing the recessive trait.
B.
Both male offspring will express the recessive trait.
C.
Both female offspring will express the recessive trait.
D.
There’s a 50 percent chance the male offspring will express the recessive trait.
Answer:
D. There's a 50% chance the male will express the recessive trait
Explanation:
Because X is dominant over Xr, a female could not express it in this punnett square because she will have the extra X chromosome. While males do not have the extra X so if they receive the Xr they will have nothing to "cover" them.

explain the circulation of blood
Explanation:
blood comes into the right atruim from the body
Answer:
The circulation of blood is where basically the blood comes or goes into the right atrium from the body, this then moves into the right ventricle and is then pushed into what is called the pulmonary arteries in the lungs of a human. Once it has picked up oxygen, the blood will then travel back to the heart through the pulmonary veins, but this time it will go into the left atrium, so to the left ventricle and including out to the human body's tissues through the aorta.
