How did the polar bears get their white fur?A.Bears have various alleles for fur color ranging from dark to light. Those bears with the lighter fur had a better chance of survival in the biome, so they lived and reproduced passing on their light colored gene to their offspring. As generations passed, white fur became more common.B.As a polar bear grows up, its fur gradually gets lighter, so by the time they are a teenager, they have fully white fur and are then best suited to survive in their environment.C.Polar Bears migrated from the Pacific Northwest up to the Tundra and Arctic because they knew that they would have a better chance of surviving in this cold region.

Un objeto posee una energía cinética de 300J, este mismo se ubica a 4m de altura y su masa corresponde a 10Kg. ¿Cuál es su energía mecánica?
Answers
Answer: 692 J
Explanation:
La energía mecánica es la energía que se utiliza para realizar un trabajo determinado y se calcula con la suma de la energía cinética y la energía potencial de un objeto. En otras palabras, describe la energía de un objeto debido a su movimiento, posición, o ambos.
La energía cinética es el trabajo necesario para acelerar un cuerpo desde el reposo hasta su velocidad final. Entonces, es la energía que posee un cuerpo debido a su movimiento. Cuando gana energía durante la aceleración, el cuerpo mantiene la energía cinética a menos que su velocidad cambie, y el cuerpo realiza la misma cantidad de trabajo al desacelerar desde su velocidad actual hasta un estado de reposo. Por otro lado, la energía potencial es la energía que posee un objeto debido a su posición con respecto a otros objetos. Los tipos más comunes de energía potencial incluyen a la energía potencial gravitacional de un objeto que depende de su distancia al centro de masa de otro objeto (La Tierra), la energía potencial elástica de un muelle o resorte extendido y la energía potencial eléctrica de una carga en un campo eléctrico.
La unidad de energía en el Sistema Internacional de Unidades (SI) es el julio, que tiene el símbolo J.
La energía mecánica se calcula de la siguiente manera (tener en cuenta que la aceleración de la gravedad es un dato tabulado de 9,8m/s^2):
Energía mecánica = Energía cinética + Energía potencial
Energía mecánica = (1/2 * masa * velocidad^2) + (masa * gravedad * altura)
Energía mecánica = 300 J + (10kg * 9,8m/s^2 * 4m)
Energía mecánica = 300 J + 392 J = 692 J
How and why do plants need to be able to respond to their environment?
Answers
Like all organisms, plants detect and respond to stimuli in their environment. Unlike animals, plants can't run, fly, or swim toward food or away from danger. They are usually rooted to the soil. Instead, a plant's primary means of response is to change how it is growing. hope it helps have a great day and I hope you pass:)
Which process is absent in animal cells?
A.(making proteins)
B.(chemical reactions)
C.(respiration)
D.(photosynthesis)
Answers
D. Photosynthesis
Animal cells do not use photosynthesis
The process that is absent from animal cells is photosynthesis. The correct option is D.
What are animal cells?
Animal cells are present in animals, and they are of two types, prokaryotic and eukaryotic cells. These cells are different from plant cells as they do not contain a cell wall.
Plants are autotrophic organisms that do the process of photosynthesis to perform the chemical reaction to make food. As animal cells are heterotrophic, they do not perform photosynthesis, and they do not contain chloroplast, but chloroplast is present in plant cells.
All other processes like making protein, chemical reactions, and respiration. These processes are performed by both animals and plant cells. These are necessary for both plants and animals.
Thus, the correct option is D. photosynthesis.

Which of the following best describes a form of genetic drift in which the animal population is depleted, thereby reducing the population's genetic diversity?
A. bottleneck effect
B. disruptive selection
C. founder effect
D. gene flow
Answers
D because it’s the populations genetic diversity
The bottle neck effect best describes a form of genetic drift in which a population of animals becomes smaller, thereby reducing the genetic diversity of the population. So, the correct option is A.
What is the Bottleneck effect?
The bottleneck effect occurs when population numbers are dramatically reduced as a result of natural disasters such as earthquakes, floods, and other natural disasters. The new population is composed of organisms that were able to survive the catastrophe whose allele frequency will be radically different from the original allele frequency.
The bottle neck effect best describes a form of genetic drift in which a population of animals becomes smaller, thereby reducing the genetic diversity of the population.
Therefore, the correct option is A.

What is the positive aspect of GMO
Answers
The pros of GMO crops are that they may contain more nutrients, are grown with fewer pesticides, and are usually cheaper than their non-GMO counterparts. The cons of GMO foods are that they may cause allergic reactions because of their altered DNA and they may increase antibiotic resistance.
Today, those who directly see the most benefits from GMOs are farmers and agricultural companies. ... GMOs are also used to produce many medicines and vaccines that help treat or prevent diseases. Before GMOs, many common medicines had to be extracted from blood donors, animal parts, or even cadavers.

Explanation:
There are multiple positive aspects of GMO, but it has many drawbacks as well. Genetically modified foods can become more resistant to disease, pests, and even natural disasters(floods, drought, etc.)
