Answer:
If the parents were both carriers.
Explanation:
Since cystic fibrosis is a recessive genetic disorder, two of the same alleles must be present in order to show, so.. for example, the genotype would be cc. The parents without the disorder must've been carriers, and their genotype would be Cc.
If you do a punnet square, Cc x Cc = 25% cc, 50% Cc, and 25% CC.

How and why do plants need to be able to respond to their environment?
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:)
1. Compact, complex animals have internal exchange surfaces that are extensively branched or folded, providing a large _____________.
2. In the _____________, nutrients are absorbed across the many fingerlike projections of the lining of the intestine.
3. In the _____________, oxygen and carbon dioxide are exchanged across the epithelial linings of sacs at the tips of tiny air tubes.
4. In the _____________, wastes are removed from the blood across the epithelial linings of excretory tubes.
5. The _____________ transports materials between the exchange surfaces of other organ systems and body cells.
6. Body cells are bathed in _______________, and exchange between body cells and the blood takes place through this fluid.
Answer:
1.) Surface area
2.) Digestive system
3.) Respiratory system
4.) Urinary system
5.) Circulatory system
6.) Interstitial fluid
Explanation:
In higher complex animals, such as the vertebrates, the internal exchange surfaces are modified in such a way to facilitate the transfer of materials from cell to cell in the body. As animal size increases, diffusion distances increase and the ratio of surface area to volume drops. Larger organisms have had to evolve specialized systems that are made up of structures that provides a large surface area for internal exchange of materials. Examples of these systems include:
--> DIGESTIVE SYSTEM: The fingerlike projections of the lining of the intestine provide a large surface area for the absorption of nutrients.
--> RESPIRATORY SYSTEM: This ends with a sac called the alveolar sac. The anatomical arrangement of capillaries and alveoli produces a very large surface area that is available for gas exchange.
--> URINARY SYSTEM: wastes are easily removed from the blood across the epithelial linings of excretory tubes.
--> CIRCULATORY SYSTEM: transports materials between the exchange surfaces of other organ systems and body cells. An example is seen in the relationship between the alveoli and the capillaries surrounding it.
For any exchange of materials to occur between cells the fluid known as the INTERSTITIAL FLUID which fills the intercellular spaces allows dissolved materials to be exchanged between body cells and the blood
Which process is absent in animal cells?
A.(making proteins)
B.(chemical reactions)
C.(respiration)
D.(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.

How is a person exposed to toxins? Explain each. (There are three ways to be exposed to toxic substances.
Answer:
Three ways to be exposed to toxic substances:
1. Inhalation - Inhalation is when we are breathing something into our lungs. For example, a firefighter may ingest toxic gasses and chemicals when entering a burning house.
2. Ingestion - Ingestion is when we are taking something by mouth. If someone eats a piece of cheese that is expired, they will most likely get food poisoning.
3. Skin contact - Skin contact is when a substance is in direct contact with our skin. For example, if someone spills an acidic substance on their arm during science class, this is considered a toxin and they may get a painful chemical burn.

Why isn't medical and chemical waste placed in landfills ? A. It would contaminate the land and water with dangerous poisons B. It would cause the landfills to fill up too quickly C. It would prevent refuse from breaking down over time D. It would contribute to global climate change
Answer:
A. It would contaminate the land and water with dangerous poisons
Explanation:
Putting medical and chemical waste into landfills has extremely dangerous consequences to the environment and public health.
If they were put into landfills, these toxic wastes would leech into the soil and groundwater below them.
These toxins can accumulate over time, and harm plants and animals.
Humans may also absorb these toxic chemicals.
So, the correct answer is A. It would contaminate the land and water with dangerous poisons
Answer:
A
Explanation:
The water and land will become contaminated which will harm or endanger all the living organisms and us humans around it. Because they use the water and land source.

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?
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
