7. Chemical
8. Chemical

Any physical change just changes the shape/form of an object (like cutting wood or blow drying hair). These are pretty reversible and they don’t change the chemical structure.
Chemical changes change the actual properties of the object, so like burning bread and acid rain!

D) Finches that eat plants all have very large beaks. 14. Based on the information in the chart, which statement is correct

Answers

Answer:

D) Finches that eat plants all have very large beaks.

Explanation:

Finches that eat plants have very large beaks because plants are big in size which can only be eaten with large beak. Those finches that lives in the environment having nuts and seeds having large beaks due to the big size of seeds and plant parts so that's why we can say that finches who feeds on plants parts have larger beaks as compared to those finches who feeds on insects.

1. List and describe the five kingdoms of life.
Who developed this system?
What is the basis for the divisions?
Why is it important to the study of biology?

Answers

Answer:

1. animal kingdom: a basic group of natural objects that includes all living and extinct animals compare mineral kingdom, plant kingdom. 2.plant kingdom: Mosses, ferns, conifers, and flowering plants are all members of the plant kingdom. The plant kingdom contains mostly photosynthetic organisms; a few parasitic forms have lost the ability to photosynthesize. The process of photosynthesis uses chlorophyll, which is located in organelles called chloroplasts. 3. Fungi kingdom: Fungi are eukaryotic organisms that include microorganisms such as yeasts, moulds and mushrooms. These organisms are classified under kingdom fungi. The organisms found in Kingdom fungi contain a cell wall and are omnipresent. They are classified as heterotrophs among the living organisms. 4. protist kingdom: The protist kingdom is a classification that includes a diverse group of eukaryotic organisms. Typically, protists reproduce asexually via mitosis and range from unicellular to multicellular organisms. 5. monera kingdom:

Explanation:

2.Carl Linnaeus Carl Linnaeus (1707–1778) laid the foundations for modern biological nomenclature, now regulated by the Nomenclature Codes, in 1735. He distinguished two kingdoms of living things: Regnum Animale ('animal kingdom') and Regnum Vegetabile ('vegetable kingdom', for plants).

3. The largest category in this system is called kingdom, and has five subdivisions: Animalia, Plantae, Fungi, Monera and Protista. All known organisms fall into one of these large categories.

4. The living organisms are divided into five different kingdoms – Protista, Fungi, Plantae, Animalia, and Monera on the basis of their characteristics such as cell structure, mode of nutrition, mode of reproduction and body organization.

What are some key elements when discussing the rotation and revolution of the Moon and Earth?

Answers

Answer:

rotation is on its axis while revolution is around the sun

Some key elements when discussing the rotation and revolution of the moon and earth are the axes of rotation of the earth and moon, distance, time periods, and effects on the tides.

What is the significance of the moon and the earth?

The moon and the earth have important relationships, such as the fact that the moon's and earth's rotation and revolution have a significant impact on tides and regulate the rise and fall of ocean water levels through gravitational pull. The distance between the Earth and the Moon also plays an important role in the rotation and revolution of both celestial bodies and regulates the climate.

Hence, some key elements when discussing the rotation and revolution of the moon and earth are the axes of rotation of the earth and moon, distance, time periods, and effects on the tides.

I'm doing the fresh fruit vs canned fruit experiment and if I prepared the fruit a different way would it effect the gelatin

Answers

Answer:

How the gelatin is prepared can affect the result.

Explanation:

To perform this experiment efficiently, you need to prepare the jelly made from fresh fruit and the jelly made from canned fruit equally. That's because if you modify the ways of preparing the gelatins, they will show many differences and you won't be able to tell if this difference was caused only by the nature of the fruits, or by the way of preparation. Therefore, the way the gelatins were prepared can modify the experiment result and leave it imprecise and unreliable.

Choose the correct ending to this sentence below and explain why? Many drugs are competitive inhibitors of specific enzymes. In such cases........
A. the amount of drug needed to achieve the same effect is increased as the substrate concentration increases.
B. the amount of drug needed to achieve the same effect is increased as the substrate concentration decreases.
C. substrate must be bound to the enzyme before the drug can bind.
D. the enzymes have to be allosterically regulated.

Answers

Answer: A. the amount of drug needed to achieve the same effect is increased as the substrate concentration increases

Explanation:

Competitive inhibition is when identical molecules to the substrate molecules gets bonded to the active site which then hinders the binding of the actual substrate. An example of competitive inhibitor is penicillin, since it blocks an enzymes active site which us used in the construction of the bacteria cell.

Then, the correct statement will be:

"Many drugs are competitive inhibitors of specific enzymes. In such cases, then the amount of drug that'll be needed to achieve the same effect is increased when the substrate concentration increases".

Therefore, the correct option is A.

What are the products of photosynthesis? (Select all that apply)
A. Oxygen

B. Water

C. Carbon Dioxide

D. Glucose (sugar)

Answers

Answer:

A. Oxygen

D. Glucose (sugar)

Explanation:

Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are products and ATP is energy that is transformed from the process.

The products of photosynthesis are oxygen and glucose along with some quantity of water. Thus, the correct options for this question are A, B, and D.

What is Photosynthesis?

Photosynthesis may be defined as a type of process through which green plants and some photosynthetic algae synthesize their own food in the form of glucose with the help of carbon dioxide and water in the presence of sunlight.

The complete reaction of photosynthesis is as follows:

[tex]6CO_2+12H_2O[/tex] → [tex]C_6H_1_2O_6+6O_2+6H_2O[/tex].

With the help of the above reaction, it is better understood that water is both a reactant and a product. While Glucose is the ultimate or crucial product of photosynthesis along with oxygen.

Therefore, the products of photosynthesis are oxygen and glucose along with some quantity of water. Thus, the correct options for this question are A, B, and D.

Que sucedería con la especie humana si debido a una futura mutación genética sus células no pudieran realizar los procesos de mitosis y meiosis

Answers

Answer:

la vida no podría continuar sin los procesos de división celular  

Explanation:

La mitosis es el proceso de división celular mediante el cual se producen dos células idénticas a partir de una sola célula. Durante la mitosis la célula crece y duplica la cantidad de ADN, con lo cual exactamente el mismo contenido de información genética es trasmitido a las sucesivas células que el proceso de mitosis va a dar origen. Por otra parte, la meiosis es un proceso celular en el cual se producen dos divisiones nucleares y citoplasmáticas (meiosis I y meiosis II) las cuales son precedidas por una fase de replicación del ADN. En la especie humana, la mitosis da lugar a células diploides (2n) con dos set completos de cromosomas homólogos, mientras que la meiosis da lugar a cuatro células haploides (n) llamadas gametos (el gameto masculino es el espermatozoide y el gameto femenino es el óvulo) las cuales contienen la mitad del número cromosómico al de la célula de origen. En organismos eucariotas pluricelulares tales como la especie humana, la función de la mitosis es producir más células somáticas (soma: cuerpo) con idéntico material genético, mientras que la función de la meiosis es producir células aptas para el proceso de reproducción, es decir, células con la mitad del material genético que se fusionarán para generar una célula diploide o zigoto a partir del cual y mediante sucesivas mitosis se desarrollará un organismo adulto.
