Answer:

The dry-out material contains spores of anthrax-causing bacteria

Explanation:

<em>Anthrax is a disease caused by a bacteria known as Bacillus anthracis. Susceptible animals get infected by anthrax when the spore of the bacteria gets into their bodies, become activated, multiply and produce toxins.</em>

The spore serves primarily as a propagating structure and also as an agent for transmitting infections. It can be transmitted by air, water, food or any other means. Bacterial spores usually have the capability to tolerate harsh environmental conditions and only become inactivated when conditions are favourable.

The dry granular powdery material constituent of the letters received by the U.S. senators must have been spores of <em>Bacillus anthrasis</em>

What period(s) show the most rapid increase in adipose tissue?
Sergio [31]

Answer:

a and b

Explanation:

The growth of adipose tissue in newborns is directly linked to the fact that they do not have proper body temperature control, so fat acts as a thermal insulator in order to maintain a constant temperature, also, breast milk density can also influence baby fat gain.

For the first six months the baby still has a lot of fluid retention and so it may give the impression that he is getting fatter, but after the first six months until the end of the first year, the baby tends to lose this fluid, decreasing on average 10% of body weight.

<u>Girls</u> in adolescence and pre-adolescence have a tendency to gain weight due to the enormous hormonal load they receive at puberty, as well as other factors such as poor diet.

The same does not happen as often in <u>boys</u> because a good part tends to have a "leap" growth in puberty, favoring weight loss. The process of fattening in teenage boys is more associated with sedentary practices and consumption of junk food.

Multicellular plants have levels of organization. What characteristics of cells makes this possible?
Nataly [62]

Answer:

The characteristics of cells to divide and convert into specialized cells makes it possible for the different levels of organizations to occur. Specialized cells perform specialized functions which are necessary for the body of each organism. The working of these specialized cells allows the formation of the specialized tissues and the levels of organizations continue. Hence, we can consider the ability of the cells to multiply and divide into specialized cells as the basic characteristic due to which levels of organization occur.
