How come one type of matter can be converted to a totally different one?
wariber [46]

Answer:

Explanation:

En física, la materia es todo aquello que se extiende en cierta región del espacio-tiempo, que posee energía y está sujeto a cambios en el tiempo y a interacciones con aparatos de medida. Se considera que es lo que forma la parte sensible de los objetos perceptibles o detectables por medios físicos.

Etimológicamente, proviene del latín materia, que significa «sustancia de la que están hechas las cosas» y que también alude a la «madera dura del interior de un árbol»;1​ la palabra está relacionada con māter («origen, fuente, madre»)2​ y se corresponde con el griego hyle3​ (de hylos: «bosque, madera, leña, material»)4​5​ que es un concepto aristotélico de la teoría filosófica del hilemorfismo.6​

El uso moderno del término va más allá de la noción clásica de sustancia, y los físicos denominan materia a cualquier entidad cuya presencia en una cierta región del espacio-tiempo conlleva que el tensor energía-impulso para dicha región es diferente de cero.

According to the theory of endosymbiosis How did cells acquirenhow did cells acquire chloroplast
stira [4]

According to endosymbiotic theory, the chloroplast evolved as a result of engulfment and assimilation of a Cyanobacteria by an eukaryotic cell.

Explanation:

  • Endosymbiotic theory supports the view that ceratain organelles of the eukaryotic cell evolved as a result of engulfment of single celled organism.
  • Evidences  that support this theory is the presence of organellar DNA.
  • It is assumed that Mitochondria evolved as a result of engulfment and assimilation of an aerobic prokaryote while Chloroplast evolved due to engulfment and assimilation of a photosythetic prokaryote by an Eukaryote.
  • After the engulfment ,these organisms however escaped the phagocytosis and began to benefit the eukaryotic Host.
  • Soon it lost many of its Genes to the eukaryotic nucleus and became dependent on the Host.
  • Thus a symbiotic association was established between the prokaryote and the host.Giving rise to cell organelles.

A population of 1,000 healthy, at risk people is monitored for one year starting on January 1st, and the development of cases of
masha68 [24]

Answer:

\mathbf{cummulative \ incidence = \dfrac{60}{1000}}

Explanation:

We recognize that total occurrence equals new cases of disease over time divided by the number of people at risk at the onset.

Mathematically:

\mathbf{cummulative \ incidence = \dfrac{New \ cases \ of \ disease \ occurrence}{Number  \ of \ population \ at \ risk \ at \ onset}}

Given that:

Number of the population at risk = 1000 individuals

New cases during Jan 1 - Dec 31 = 60 because;

At 20 occurred on June 30 & 40 on Sept. 30) & no new cases were identified after that:

∴

\mathbf{cummulative \ incidence = \dfrac{60}{1000}}

Each of the following statements concerning hair is true except
Levart [38]

Answer: A. scalp hairs grow constantly throughout life.

Explanation:

Hair is a squamous keratinized epithelium which is consist of multi-layered flat cells.  Hair are made up of protein called "keratin".

The statement "scalp hairs grow constantly throughout life" is false because at a particular age or due to several factors scalp hairs stop growing.

Scalp hair growth rate depends on three main factors including sex (female hair grows faster than male), age (hair growth slows with age), and ethnicity (Asian hair grows slower than Caucasian hair).

Scalp hair growth stops because of  follicle devitalization when the hair length become two or three feet.

Hence, the correct answer is A. "scalp hairs grow constantly throughout life".
