Saliva, produced by glands in the mouth, plays an important role in the digestion of food. Saliva contains a chemical, called amylase, that breaks down starch in the food we eat. A scientist conducts an experiment to investigate at which temperatures amylase works the best. He hypothesizes that the reaction will occur fastest if the amylase reaction is conducted near the normal human body temperature of 37ºC (degrees Celsius). In order to test his hypothesis, the scientist measures the reaction rate, which is how fast the amylase breaks down the starch at six different temperatures. The reaction rate is rated on a scale of 0 to 10, with 0 meaning no reaction and 10 meaning the fastest reaction. The results are recorded in the data table.

AMYLASE REACTION RATE BY TEMPERATURE

20 4
40 10
60 8
80 2
100 0
Based on the data, should the scientist accept or reject his hypothesis?
A He should reject the hypothesis because amylase reacts at all temperatures.
B He should accept the hypothesis because amylase reacts only at body temperature.
C He should reject the hypothesis because amylase reacts faster above body temperature.
D He should accept the hypothesis because amylase reacts fastest near normal human body temperature and slower above and below normal human body temperature.

Answers

Answer 1

Based on the data, he should accept the hypothesis because amylase reacts fastest near normal human body temperature and slower above and below normal human body temperature.

The correct option is C.

What is the rate of a reaction?

The rate of a reaction is the rate at which reactant molecules are used up or the rate at which products are formed.

In the body, the molecules that speed up the rate of the reaction occurring in the body are called enzymes.

Enzymes are mostly proteins and thus, are easily denatured by heat.

Enzymes function best at temperatures close to the body temperature of  37ºC (degrees Celsius).

An example of an enzyme is amylase found in saliva.

Amylase is responsible for the digestion of starchy foods.

Based on the results of the experiment conducted by the scientist, it can be concluded that his hypothesis is correct.

Explain the role of aquaporins in the rapid movement of water through some cells

Answers

Answer:

In the early 1990s, aquaporins were discovered, and it was found that they can selectively control water movement into and out of cells. One of the critical functions of aquaporins is that while they allow the passage of water they prevent the passage of ions.

Con ayuda de un microscopio se observa una bacteria en el agua transcurridas (2) se miran muchas bacterias . Que ocurrio alli ,que tpo de reproducccion sucedio meiosis o mitosis

Answers

Answer:

Ninguna de las dos. No ocurre ni mitosis ni meiosis.

Probablemente haya ocurrido fisión binaria/bipartición.

Explanation:

En este caso estamos hablando de bacterias, organismos unicelulares procariotas. Estos tienen una forma de reproducción asexual denominado fisión binaria. Los eucariotas por su parte pasan por periodos de división celular implicada en el crecimiento denominado mitosis, y división celular implicada en reproducción sexual, denominada meiosis.

La fisión binaria, también conocida como bipartición, si bien muy parecida a la mitosis en algunos aspectos, es la forma de reproducción de las bacterias.

Ambas, mitosis y fisión binaria, implican un duplicado de material genético. El ADN se duplica y una copia va a cada célula hija. Lo mismo sucede con el resto del contenido celular. Finalmente ocurre citocinesis. Sin embargo, a diferencia de la bipartición, la mitosis requiere de mecanismos mucho mas complejos de duplicación celular e involucra también a la cariocinesis, ausente en bacterias.

La fisión binaria ocurre muy rápidamente, en un breve período de tiempo puede hallarse una diferencia considerable en la cantidad de células presentes en un sustrato, producto de esta división. Es por esto que el crecimiento que exhiben las bacterias como población, sigue un modelo exponencial.

Imagine a population of moths. White moths are easier for birds to see and eat. Black moths blend into their surroundings, so they are less visible to birds than white moths. As a result, black moths are more likely to survive and reproduce, enabling the gene for black coloration to be passed on to the next generation. This increases the frequency of genes for black coloration in the population. Which evolutionary process does this scenario describe

Answers

Answer:

The correct answer is - natural selection.

Explanation:

Natural selection is a process of adapting according to the environmental change in order to survive and reproduce and increase their number. It is represented by Darwin for the first time. Natural selection leads to evolution.

In this case, White moths adapt according to the environment by increasing the population of black moths in order to blend with the surrounding and as the result, black moths are more likely to produce and survive and passed this trait to the next generation.

What do you need to create a chemical bond?

Answers

A chemical bond is a force of attraction between atoms or ions. Bonds form when atoms share or transfer valence electrons. Valence electrons are the electrons in the outer energy level of an atom that may be involved in chemical interactions.

Answer:

A strong chemical bond is formed from the transfer or sharing of electrons between atomic centers and relies on the electrostatic attraction between the protons in nuclei and the electrons in the orbitals. The types of strong bond differ due to the difference in electronegativity of the constituent elements.
