Answers
Answer:
Digestion, excretion and transportation of substances.
Explanation:
Chemical reactions such as breakdown of food, cleaning of blood and absorption of nutrients and digestion are the activities that our body done with the use of energy. Digestion of food needs energy for the breakdown of food with the help of several enzymes. Transportation of waste materials and other substances also needs energy. Our cells absorb nutrients with the help of energy molecules through active transport.

The tiny fruit fly is a superstar of genetics research. Thousands of experiments have explored how flies inherit traits. Wing shape, body color, eye color, and head shape are a few traits under investigation. Fruit flies make good study subjects because they are inexpensive, take little space, and breed quickly. In addition, humans and fruit flies share 75% of their disease genes. By studying fruit-fly genetics, we can learn about human illness.
Short-winged fruit flies studied in the lab cannot fly because they have an allele that causes them to grow tiny wings (w). Normal fruit flies, known as “wild-types”, have fully functional wings (W). The wild-type wing is the dominant allele.
If you cross one short-winged fly (ww) with a wild-type fly (WW), what is the probability of getting a short-winged offspring in the F1 generation?
Explain your reasoning.
Answers
Answer:
The probability of getting a short-winged offspring in the F1 generation is 0. .Explanation: When you cross a WW parent with a ww parent, all the offspring will get one W and one w allele from their parents. They will have the genotype Ww. To have short-winged offspring, the genotype must be ww. The dominant wild-type allele (W) will make all offspring that will have functional wings

Barrera que delimita a la celula y que contiene sus organelos y los productos generados dentro de la misma , a traves de ella entran nutrientes y expulsan desechos
Answers
Answer:
Membrana celular
Explanation:
La membrana plasmática o membrana celular, presente en todas la céluas, la protege y encierra a distintas organelas, que al estar aisladas deñexterior, funcionan como una unidad difereciada. Aun asi, cada célula mantiene comunicación con otras células a partir de esta membrana. Esta estructura, a parte, permite el paso de sustancias desde y hacia el iterior celular. Moleculas necesarias para el adecuado funcionamiento de la celula ingresan a la misma, mientras que otras destinadas a exportación, desechos, mentenimiento del equilibrio, etc, salen al espacio intercelular. Las membranas biológicas estan formadas por una bicapa lipídica. los lípidos se posicionan de manera tal que las cabezas hidrofilicas apuntan hacia el exterio e interior celular, mientras que las colas hidrofóbicas se disponen hacia el interior de la bicapa. Las membranas celulares son fluidas, es decir que las moleculas que la componen tienen la capacidad de moverse.
Dentro de la célula, e incluidas en el citoplasma, hay varias organelas que también se encuentran delimitadas por membrana, tales como nucleo, reticulo endoplasmático, aparato de golgi, mitocondrias, cloroplastos, vacuolas y vesiculas. El contenido de estas organelas se encuentra aislado del citoplasma gracias a la contención de la membra.
Which of the following statements is not an example of evolution that has resulted from human activity? Group of answer choices Some insect species are now resistant to pesticides. Many strains of bacteria are now resistant to some commonly used antibiotics. Like certain other crops, domesticated strawberries are larger than wild strawberries. Because of hunting, organisms such as bears and wolves are fewer in number.
Answers
Answer:
The correct answer is - Because of hunting, organisms such as bears and wolves are fewer in number.
Explanation:
Evolution is the change in the characteristics or traits of the species that are developed over several generations by the process called natural selection. Natural selection is the process of transferring the genes or traits that help in the survival of organisms.
Among the given statements all the are the example of the evolution that is resulted from human activity except the extinction or fewer the bears and wolves due to hunting. Other examples are showing evolution as they developed characteristics over generations.

What do you think selectively permeable means?
A. The membrane lets nothing in or out.
B. The membrane lets certain substances move across it freely, while others must move through a “gate”.
C. The membrane lets everything in and out.
Answers
Answer:
B. The membrane lets certain substances move across it freely, while others must move through a “gate”.
Explanation:
Selective permeability is a property of cellular membranes that only allows certain molecules to enter or exit the cell. This is important for the cell to maintain its internal order irrespective of the changes to the environment. For example, water, ions, glucose and carbon dioxide may need to be imported or exported from the cell depending on its metabolic activity. Similarly, signaling molecules may need to enter the cell and proteins may need to be released into the extracellular matrix. The presence of a selectively permeable membrane allows the cell to exercise control over the quantum, timing and rate of movement of these molecules.
B. The membrane lets certain substances move across it freely, while others must move through a “gate”.
