Answer:
La respuesta correcta es "el átomo esta compuesto por electrones de carga negativa embebidos dentro de un protón positivo, tal como un pudín de pasas".
Explanation:
El modelo atómico de Thomson, también conocido como el modelo de pudín de pasas, describe el átomo como un elemento compuesto por electrones de carga negativa embebidos dentro de una nube de carga positiva, tal como un pudín de pasas. Thomson fue el científico que descubrió los electrones en 1904, año en el que no se tenía mucha información aún de la interacción de las partículas subatómicas. En el modelo atómico de Thomson los electrones estaban distribuidos uniformemente, flotando alrededor de una nube de carga positiva.

Answer:
because a lot of the energy has been lost to its surroundings
Explanation:
Assume Deb eats three 150-gram bags of potato chips each day. Use the USDA food database to calculate Deb’s calorie consumption and the number of grams of protein, carbohydrates (by difference), and the total fat that she eats. You may use any brand of potato chips in the database, but state the brand in your answer.
Answer:
Let’s consider that she eats Herr’s Baked Ripple Cut Potato Chips. If she ate a total of 450 grams of these potato chips every day, she will consume about 1,930 calories, 32.13 grams of total fat, 32.13 grams of protein, and 353.36 grams of carbohydrates.

In roses, red flowers and long stems are dominant traits. A rose plant that is homozygous for both red flowers and long stems is
crossed with a rose plant that is heterozygous for red flowers and homozygous for short stems. What percentage of the offspring
will exhibit red, long-stemmed flowers?
25 percent
O 50 percent
O 75 percent
O 100 percent
Answer:
This is late but the answer is 100%
Explanation:
I got a 100 on the test
The percentage of the offspring that will exhibit red, long-stemmed flowers is 100 percent; that is the last option as all of the offspring will show dominant traits, which are red, long-stemmed.
What is genetic crossing?In the context of genetics, traits are characteristics that are passed down from parents to offspring through their genetic material (DNA). These traits are determined by genes, which are segments of DNA that contain the instructions for the development of a particular characteristic. Here, the gene for flower color in roses has two alleles: R (red) and r (white). The R allele is dominant, and the r allele is recessive. Similarly, the gene for stem length has two alleles: L (long) and l (short). The L allele is dominant, the l allele is recessive, and from the cross, all will be dominant.
Hence, the percentage of the offspring that will exhibit red, long-stemmed flowers is 100 percent; that is the last option.

What is a good property of an indicator?
Answer:
Acid base indicators are weak and acids and bases, which are used to signify the end point of neutralization reaction. The type of indicator used for a neutralization reaction depends on the strength of the acid and the base, that are involved in the reaction. A good acid base indicator must have a good pH range and it must be able to produce specific and identifiable color in specific acid base medium.
or
Two good properties of an indicator are as follows-
1) It should be specific- It means that the changes, which are measured by the indicator should be expressed in precise terms so that appropriate assessment could be made.
2) It should be time bound- This means that the measurable changes should arrive withing a particular time limit.
Example of indicator- Litmus is an acid base indicator that turns acidic solutions red and basic solutions into blue color.

The cause of humanity's increased water consumption is an increased population. What is the effect?
Option are not provided in the question. The complete question is as following:
The cause of humanity's increased water consumption is an increased population. What is the effect?
A. less potable water, a growing threat to biodiversity
B. more potable water, a growing threat to biodiversity
C. less potable water, a decreased threat to biodiversity
D. more potable water, a decreased threat to biodiversity
Answer:
A. less potable water, a growing threat to biodiversity
Explanation:
The increasing population of human causes increase in water consumption that leads to reduction in portable water, which is a growing threat to biodiversity .
Portable water or freshwater is used for drinking by humans beings along with that it provide habitat to many diverse marine wildlife and they are important to local ecosystems as they provide sources of income and food to humans and other wildlife.
Freshwater or portable water play very important role to control flood and erosion.
So, decrease in portable water result into decrease in biodiversity.
Hence, the correct option is A. less potable water, a growing threat to biodiversity .

4 cells of the body
Answer:
cells of the body
Explanation:
Respiration happens in the cells of plants, animals and humans, mainly inside mitochondria, which are located in a cell’s cytoplasm, energy released during respiration is used by plants to make amino acids, and by animals and humans to contract their muscles to let them move. Don't confuse respiration with breathing. Respiration releases energy, while breathing

The gluten-free diet was originally intended for people with celiac disease, but it’s now become a new fad diet for the general population. Many people state that gluten-free diets are beneficial for people who aren’t sensitive to gluten, while others suggest that there’s no benefit. Use credible resources to evaluate the argument yourself. Do you think there’s sufficient scientific evidence to support the use of a gluten-free diet in people who aren’t sensitive to gluten? Provide evidence that supports your argument.
Answer:
The gluten free diet is helpful for the people that are sensitive to food with gluten it which occurs due to the celiac disease. It was originally meant for the such people but it becomes a new fad. However, there is no compelling evidence to support that gluten free diet helps in health improvements n non sensitive people.
In other hand there are majority of doctors are against the use of gluten free diet is not good for various body organs like heart. A study concluded that there are lower risk of heart disease in people take more gluten. Doctors and various study suggests that people with no celiac disease should not avoid gluten.
Answer:
There’s no benefit to a gluten-free diet for people who aren’t sensitive to gluten. Many websites state benefits of a gluten-free diet. These benefits range from weight loss to improved heart health. None of these sites backed up their claims with scientific research. More credible sites consistently state that there’s no scientific research to back up these claims.

A student observed a dying plant in the corner of their science classroom. They learned the process of Photosynthesis and Cellular Respiration already in class. The students were trying to remember the correct chemical equation for the process. In order for the plant to be successfully creating its own food which chemical equation did the student write correctly?
Answer:
The general chemical equation for photosynthesis is
6CO2 +6 H20 → C6H1206 + 602,
Where CO2 is carbon dioxide, H20 is water, C6H12O6 is glucose, and O2 as oxygen a byproduct.
the process begins with the splitting of water molecules-Photolysis.
2H20 +2 NADP + 8 Photons → NADPH + 2H+2 O. Photons is sunlight that splits the water molecules.
Cellular respiration is the reverse of the process which is the
C6H1206 +6 O2 → 6H20 +6 CO2 +ATPs.
ATPs is the chief product, while C02 is the byproduct.

why is waters high specific heat good for living things
Answer and Explanation:
Water's high specific heat means that the temperature of the water takes a long time to change. Living things that live near bodies of water experience temperatures different than inland, which is typically advantageous. During the summer, water remains cooler than the air for a period of time, and in the winter, the water remains warmer than the air for a period of time. In turn, the air in the areas with a body of water is typically increased or decreased a few degrees in temperature depending on the season. In the winter, this also produces what is called the "lake effect", in which snow is produced during cooler atmospheric conditions when a cold air mass moves across long expanses of warmer lake water.
