Explain what genetic engineering is, and give real life examples (more than 1) of humans introducing a gene from one creature/plant into another creature/plant. Why did humans do this? Was it successful? Help me please this is due in around 3 hours
Answers
Answer:
Genetic Engineering also known as genetic modification are techniques used to transfer genes from the cells of a donor organism to those of a recipient.
One example is the formation of golden rice. 3 types of genes are added. Two come from daffodils and one from a bacterium, together forming beta-carotene, the chemical which give carrots their colour hence the name 'golden rice'. This is an advantage in LEDCs as beta-carotene is converted to vitamin A, which could save the eyesight of millions of children.
Another example are bananas. The genes that produce antigens to a certain disease are taken and transferred to bananas. The antigens contained in the banana will stimulate an immune response. This has successfully prevented diseases, and it will not be necessary to get needles stuck in you. This can be a very efficient method of preventing diseases in countries that has bananas as their main source of calories.
What combinations (four for each) can you make with this genetic code? YyRR x YYRr
Answers
Answer:
YyRR - YR, YR, yR, yR
YYRr - YR, Yr, YR, Yr
Explanation:
According to this question, the following genotypes of organisms are given; YyRR and YYRr. In order for sexual reproduction to occur, these genotypes must undergo meiotic division to produce gametes. Based on the law of independent assortment, alleles of each gene separates into gametes irrespective of independently of one another.
The combination of alleles in each gamete occurs in such a way that only one allele of each gene is present in each gamete. Based on this, the following parental genotype have the following four (4) gametic combinations:
YyRR - YR, YR, yR, yR
YYRr - YR, Yr, YR, Yr

The bushes have alleles for blue and red berries. Bushes with both red and blue alleles make purple berries.
If the birds only like to eat blue berries, what is the selective pressure the birds are putting on the bushes?
For more plants to have red
berries.
For more plants to have purple
berries.
For more plants to have blue
berries.
Submit
Answers
Answer:For more plants to have blue berries
Explanation:
If the birds only like to eat blue berries in an environment with blue and red berries, the birds are putting selection pressure for more plants to have red berries.
Selection pressures are factors that act to boost or limit the organism's capacity to thrive in an environment. It could be biotic or abiotic.
The availability of purple berries in the environment is dependent on the mixing of both blue and red berry alleles.If birds keep picking on the blue berries, it means fewer blue berries would be available to mix with red berries in order to produce purple berries.Hence, fewer blue and purple berries would be available in the environment with time leaving only red berries to thrive.In other words, the continuous picking on blue berries by birds will only increase the availability of red berries with time.

Scientists collected samples of each group of flies. They placed some of the flies, together, in flasks with both apples and hawthorn
fruit. Other flasks contained either apple-eating flies or hawthorne-eating flies. Only the flies in the single fruit flasks mated and
produced offspring. To confirm their results, the scientists isolated flies from each group and put one of each into a flask with food.
Eventually the flies died
without mating. What conclusions apply to this situation? All BUT ONE could apply.
A)One fly species became two species via natural selection.
B)By eating different fruits, the flies changed genetically.
C)Over time, each group evolved different traits that aided in their survival.
D)Living in the ground and emerging a different times was a kind of

¿Por qué consideras importante la medición de propiedades y/o fenómenos en las ciencias experimentales?
Answers
Answer:
una medición debe ser precisa y objetiva ya que sólo de este modo es posible reproducir el diseño experimental en condiciones controladas
Explanation:
Las ciencias experimentales son aquellas que realizan estudios en condiciones controladas (experimentos) con el objetivo de comprender el mundo natural que nos rodea. La medición juega un papel crucial en las ciencias experimentales ya que sólo una medición precisa y objetiva permite reproducir los resultados obtenidos en diferentes experimentos. De este modo, el proceso de cuantificar magnitudes está directamente asociado a la confiabilidad de los datos obtenidos en un experimento y consecuentemente también a la confiabilidad de las conclusiones derivadas de la aplicación del método científico experimental.

What food item will provide c in the least mass? What is that mass?
What food item will provide a minimum of 1 mole of both sodium and potassium with the least mass? What is that mass?
Answers
Answer:
Can of soup and pop Tarts.
Explanation:
Can of soup will provide 1 mole of sodium whereas pop Tart provides potassium in the least mass because the concentration of sodium and potassium in can of soup is higher than other food items. The can of soup has 300 mg of sodium and pop Tart has 0.5 g of potassium while on the other hand, honey nut, frosted flakes, Oreos and pop Tarts has 0.14 g, 0.12 g, 0.3 g, and 0.35 g of potassium respectively and can of soup, honey nut, frosted flakes and Oreos has 190 mg, 150 mg, 80 mg, and 180 mg of potassium respectively which is lower than pop Tart so we can say that less amount of pop tart provides more potassium. 9579 of soup and 7505 of pop Tart are the masses required for I mole sodium and potassium.
