C. Temperature and pH can affect how enzymes work.
Answer:
A) A tentative statement used to guide a scientific investigation is called scientific hypothesis.
As hypothesis is a proposed details of a phenomena, it can guide us in one way or another to carry out the scientific investigation.
B) Makes prediction about future events is scientific hypothesis.
Scientific hypothesis bases on the observation made predicts about future events, which could be either true or false.
C) Can be tested many independent researches is a scientific theory.
A scientific theory is developed when it has been passed through many researches and had gained acceptance too.
D) Both Scientific theory and hypothesis are based on the observations of the natural phenomena.
Firstly, an observation is made based on natural phenomena, which leads to questions, then research or study is carried out to answer these questions leading to the formation of a hypothesis which upon successful testing forms a theory.
E) Scientific theory is a well-established highly reliable explanation.
It a highly sustained explanation based on facts of nature, that are confirmed via a lot of experiments.

Ears
¿Qué es el oído y qué hace?
El oído consta de tres partes diferentes, que funcionan conjuntamente para captar sonidos y transmitírselos al cerebro: el oído externo, el oído medio y el oído interno.
El oído externo
El oído externo está formado por el pabellón auditivo (también conocido como "pabellón auricular" o "pabellón de la oreja") y el conducto auditivo. Los pabellones auditivos son las partes visibles que tenemos a ambos lados de la cabeza y están compuestos por cartílago duro cubierto de piel. La principal función del pabellón auditivo consiste en captar sonidos y conducirlos hacia el conducto auditivo, que conecta con el oído medio. Las glándulas de la piel que recubren el interior del conducto auditivo fabrican cera o cerumen, que protege este conducto, eliminado la suciedad y ayudando a prevenir posibles infecciones.
El oído medio
El oído medio es una cavidad llena de aire que transforma las ondas sonoras en vibraciones y las transmite al oído interno. El oído medio está separado del externo por el tímpano (o membrana timpánica), una fina lámina de tejido que va de lado a lado del conducto auditivo y que está fuertemente tensada sobre él. Los sonidos golpean el tímpano, haciendo que se mueva.

Answer:
A substance that removes carbon dioxide gas
Explanation:
Options-
A. A substance that removes carbon dioxide gas
B. A plant to produce oxygen
C. A glucose reserve
D. A valve to release excess water
Solution -
It is given that the rate at which oxygen is consumed and the rate at which carbon dioxide is produced is same. Therefore, if we somehow are able to measure the volume of carbon dioxide, we can interpolate the rate of consumption of oxygen from it.
Hence, A substance that removes carbon dioxide gas is essential to provide accurate volumetric measurements of oxygen gas consumption
Option A is correct
