Answer:
Each apron costs $ 12.75, and to make a profit of $ 1.75 they should be sold for $ 14.50.
Explanation:
Since the fifth grade craft club is making aprons to sell, and each apron take 1.25 yards of fabric that costs $ 3 per yard and 4.5 yards of trim that costs $ 2 per yard, to determine what does it cost the club to make one apron, and, if the club wants to make $ 1.75 profit on each apron, how much should they charge per apron, the following calculations must be performed:
1 apron = 1.25 yards of fabric at $ 3 per yard and 4.5 yards of trim at $ 2 per yard
1.25 x 3 + 4.5 x 2 = X
3.75 + 9 = X
12.75 = X
12.75 + 1.75 = 14.50
Therefore, each apron costs $ 12.75, and to make a profit of $ 1.75 they should be sold for $ 14.50.
differentiate between centosome and chromosome
Explanation:
Centrosomes is a clear space of cytoplasm located close to the nucleus. Whereas the chromosome is a highly coiled stricture contained in the nucleus.
Centrosome has usually one present per cell. Chromosomes can have one or more.
Centrosome consists of two rod-like strictures made of the protein tubulin. Chromosomes consist of DNA coiled around the histone protein core.
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.

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.

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
What is the main way that fossil fuel use impacts the environment?
A) invasive species
B) water use
C) global climate change
D) soil degradation
Answer:
C. Global Climate Change
Explanation:
When fossil fuels are burned, they release carbon dioxide and other greenhouse gases, which in turn trap heat in our atmosphere, making them the primary contributors to global warming and climate change.
Global climate change is the main way that fossil fuel use impacts the environment. Therefore, option (C) is correct.
Why fossil fuels impact environment?Fossil fuels such as coal, oil, and natural gas are formed over millions of years from the remains of dead plants and animals. When these fuels are burned to produce energy, they release large amounts of carbon dioxide and other greenhouse gases into the atmosphere.
These gases trap heat from the sun and cause the Earth's temperature to rise, leading to climate change and other environmental impacts. In addition to greenhouse gas emissions, fossil fuel extraction, transportation, and processing can also have other negative impacts on the environment, including air and water pollution, habitat destruction, and oil spills.
Fossil fuel use also contributes to the depletion of finite resources and the loss of biodiversity. As a result, there has been increasing emphasis on transitioning to renewable energy sources to mitigate the negative impacts of fossil fuels on the environment.

How is DNA condensed in order to fit inside cells?
Explanation:
DNA is tightly packed up to fit in the nucleus of every cell. As shown in the animation, a DNA molecule wraps around histone proteins to form tight loops called nucleosomes. These nucleosomes coil and stack together to form fibers called chromatin.
compare the mechanism of gaseous exchange between an insect and a mammal
Explanation:
Insects have water at the ends of their tracheoles for oxgen to dissolve in to diffuse. ...

Explanation:
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

how does the structure of the leaf allow it fulfil the requirements for gas exchange surface?
(pls don't put it in a file or pls no link) :)
Explanation:
The structure of the leaf is adapted for gas exchange. The cells in the spongy mesophyll (lower layer) are loosely packed, and covered by a thin film of water. There are tiny pores, called stomata , in the surface of the leaf. Most of these are in the lower epidermis, away from the brightest sunlight.
The stomata control gas exchange in the leaf. Each stoma can be open or closed, depending on how turgid its guard cells are.
In the light, the guard cells absorb water by osmosis, become turgid and the stoma opens.
In the dark, the guard cells lose water, become flaccid and the stoma closes.
Diffusion of carbon dioxide, oxygen and water vapour into (or out of) the leaf is greatest when the stomata are open.
