Describe two potential biological risks of large scale cultivation and use of such genetically modified plants
expeople1 [14]
Risk of large scale production:
1. With an increase in production, there can become managerial problems. Workers can become lax, making of decisions become difficult and communication between workers become hard.
2. A large scale operation, needs technical tools like machines. Finance to buy machines can become a problem and hamper growth.

Risk of Genetically modified plants
1. They can become contaminants. The cross pollinated plants and seeds can travel, and contaminate the gene pool. Thereby, threatening future generations of plants.
2. They can produce side effects. Engineered plants, can lead to development of new toxins, carcinogens and deficiencies of nutrition.

When heart muscles cells are deprived of oxygen, the heart still pumps. what must the heart cells be able to do? transform lacta
katrin2010 [14]
The heart cells must be able to continue aerobic metabolism when skeletal muscle cannot. Aerobic metabolism is a part of cellular respiration and involves body cells making energy through glycolysis, the citric acid cycle, and the electron transport/oxidative. It is done in the heart at a rate below 85% of maximum heart rate and does not use vigorous muscle contraction. fatty acids , ketone bodies and carbohydrates are the primary substrates of the heart metabolized to generate ATP. The metabolic demands of the heart are the largest than any other organ in the body, and normal cardiac metabolism is required to fuel contractile function and viability.

The evolution of similar forms in different lineages when exposed to the same selective pressures is.
luda_lava [24]

The evolution of similar forms in different lineages when exposed to the same selective pressures is<u> convergent evolution. </u>

<u></u>

Convergent or divergent evolution are related to the involved groups, the environments, the selective pressures, and the way in which organisms deal with them to achieve a better adaptation increasing their fitness.

<h3>What is convergent evolution?</h3>

Convergent evolution is the emergence of phenotypical similarities in different groups independently from each other.

Convergent evolution occurs when two or more taxonomic groups share the same traits or characteristics even when they do not share a common ancestor.

Usually, this is a pattern observed in groups that are exposed to the same or similar environmental pressures. The development of these similar phenotypes is related to higher fitness and competitive ability.

The evolution of similar forms in different lineages when exposed to the same selective pressures is <u>convergent evolution. </u>

Which detail from the excerpt develops the idea that scholars faced many challenges in deciphering the meaning of the
Ratling [72]

Read the excerpt from The Riddle of the Rosetta Stone, by James Cross Giblin.

Another, more complete copy of the same decree that appeared on the Stone was found on a slab at Philae in 1848. Fuller translations of the hieroglyphic text soon followed. A Latin version came out in 1851, a French one in 1867, and an English one in 1871. But many of the hieroglyphs on this slab were missing also, so only a few words and phrases could be added to what was already known from the Rosetta Stone.

Which detail from the excerpt develops the idea that scholars faced many challenges in deciphering the meaning of the decree on the Rosetta Stone?

Answer:

many of the hieroglyphs on this slab were missing

Explanation:

The detail from the excerpt that develops the idea that scholars faced many challenges in deciphering the meaning of the decree on the Rosetta Stone is "many of the hieroglyphs on this slab were missing."

From the available excerpt, it was written that despite many translations of the original text, including the fuller version, the French translation, the Latin version, and the English version, "many of the hieroglyphs on this slab were missing also, so only a few words and phrases could be added to what was already known from the Rosetta Stone."
