nexus9112 [7]

The question is incomplete as it does not have the options which are:

resistant

semisynthetic

synthetic

natural

Answer:

Semisynthetic

Explanation:

Antibiotics are the microbial compounds which are obtained from the micro-organisms which are found effective against the bacteria as they act by inhibiting the activity of the bacteria which ultimately kills the bacteria.

These antibiotics can also be distinguished based on their synthesis: natural, semi-synthetic and synthetic antibiotics.

The semi-synthetic antibiotics are the antibiotics which are obtained from the microbes but are modified artificially by making chemical changes to increase the effectiveness of the antibiotic and making the antibiotic as broad-spectrum bacteria.

Since the properties of the antibiotics provided in the question are similar to the semi-synthetic antibiotics, therefore, is considered semi-synthetic bacteria.

Thus, Semisynthetic  is correct.

The most basic universal indicators of human development are ______________. select all that apply.
Gnoma [55]
<span>The most basic universal indicators of human development are life expectancy, literacy, and standard of living. Only health would not be considered as part of these indicators, because it doesn't say anything about human development. Life expectancy refers to the length of someone's life. Literacy is the state of being literate, meaning knowing how to read and write. Standard of living is self-explanatory - whether you live good and have money or the opposite.</span>

In 1918, the Russian Tsar Nicholas II was deposed, and he and his family were reportedly executed and buried in a shallow grave.
Arte-miy333 [17]

Answer:

This can be evaluated with DNA test- by comparing the mitochondrial DNA (mtDNA)of the Tsar family with the woman-Anastasia. <u>Maternal DNA is inherited uninterrupted from generation to generation </u>

Explanation:

The living consort of Queen of Elizabeth ,Prince Philip, <u>is a grand nephew of Tsar Nicholas 11.</u> They  shared the same maternal ancestry.

Therefore, his   mitochondrial   must be maternal, and compatible with that of the Tsar Nicholar. Male children always inherit maternal mitochondria (mtDNA)and  passed from generations to generation.

T<u>he blood samples of prince Philip can be  taken, to extract the mtDNA,and matched  with the sample  of mtDNA obtained from the exhumed bodies of the Tsars,</u><u> </u>to reaffirmed the compatibility of the ancestry .  

If sample of the compatible mtDNA,  from price Phillip was compared with the mtDNA of the woman who claimed to be Anastasia, her claim can be validated.

Matched sample  shows she was the daughter, while negative result proves otherwise.

Do you think there is a relationship between heart rate and blood flow?
zaharov [31]

Yes, there is a relationship between heart rate and blood flow.

<u>Explanation:</u>

The relation ship between the heart rate and blood flow is that with the increase in heart rate, the flow of the blood also increases but the increase in the flow of the blood is not as fast as the rate of beating of heart increases in comparsion.

Even though the heart is beating more times in a minute, healthy blood vessels get larger amount of blood to flow in an easier way when heart beat gets faster.
