In the diagram below, Strands I and II represent complementary sections of DNA. The sequence of Strand I is shown. What is the sequence of Strand II?
Strand I CTAC Strand II ????
AGCA
CTAC
TCGT
GATG
STRAND 1 AND 2 ARE THE DIAGRAM!!!!
Answer:
GATG, TCGT, ACGA, CATC
Explanation: C goes with G, and A goes with T but in a RNA then the T swaps with a U
The sequence displayed by Strand II would be:
A). GATG
RNA is denoted as the RiboNucleic Acid that exemplifies a molecule/atom which has similar characteristics as of the DNA. However, in RNA, the letter 'T' is replaced with "U" and vice versa. In the given diagram, Strand I shows "CTAC" and thus, Strand II will show "GATG."Thus, option A is the correct answer.Learn more about "Sequence" here:

What happens if there is a mutation in the DNA? What are the effects of a mutation?
Answer:
When a gene mutation occurs, the nucleotides are in the wrong order which means the coded instructions are wrong and faulty proteins are made or control switches are changed. The body can't function as it should. Mutations can be inherited from one or both parents. They are present in the egg and/ or sperm cells.

Explanation:
The ecological efficiency at each trophic level of a particular ecosystem is 20%. If the green plants of the ecosystem capture 100 units of energy, about ____ units of energy will be available to support herbivores and about ____ units of energy will be available to support carnivores
Answer:
1. 20 units
2. 4 units
Explanation:
In an ecosystem, energy is transferred from one organism occupying a trophic level to another as they feed on one another. The amount of energy that is being transferred as the chain progresses is called ECOLOGICAL EFFICIENCY. According to this question, the ecological efficiency at each trophic level of the ecosystem is 20%. This means that about 20% of energy units will be transferred to the next trophic level.
If the green plants of the ecosystem capture 100 units of energy, the amount of energy that will be available to support herbivores (plant eaters) is: 20% × 100units i.e. 20/100 × 100 = 20 units.
Also, the amount of energy that will be available to support carnivores subsequently will be 20% of 20 units i.e. 20/100 × 20 = 4 units.

how can we determine the probability that an organisms expressed version of a trait will be passed on to it's offspring?
Answer:
Punnet square
Explanation:
I am pretty sure this is it
By using Punnett square we can determine the probability that an organism's expressed version of a trait will be passed on to its offspring.
What is Punnett square?Reginald. C Punnett invented the Punnett square, a square shape diagram used to forecast the genotype and phenotype of offspring from a breeding experiment by crossing the genes of the parents.
The diagram's number of Punnett squares is determined by the number of attributes employed. After creating the boxes, one parent's gene is placed on top and the other parent's gene is placed on the left side.
In the event of a monohybrid cross, just one letter with a single characteristic crosses one box, whereas two letters with two separate traits cross one box.
The number of alternative genotypes of offspring is obtained by crossing the characteristic.
Thus, the Punnett square helps in determining the probability that a trait will be passed on to its offspring.

¿Que pasa cuando ingerimos algunas sustancias adictivas? A: Afectan nuestro sistema circulatorio B: Afectan nuestro sistema respiratorio C: Afectan principalmente a nuestro sistema nervioso central
Answer:
C: Afectan principalmente a nuestro sistema nervioso central
Explanation:
Al ingerir sustancias adictivas, el principal afectado o influenciado es el sistema nervioso. Aunque existen diversas formas de acción de las sustancias adictivas, en general, éstas actúan afectando el pasaje dopaminérgico.
La dopamina es un neurotransmisor liberado por el sistema nervioso central que causa sensación de placer. Es conocido como la "hormona del placer" y esta relacionado con la evolución de las adicciones. Las diversas sustancias adictivas alteran el funcionamiento normal del sistema nervioso, provocando un exceso de liberación de dopamina. Esta excesiva sensación de placer al consumir sustancias adictivas es lo que nos lleva a seguir consumiendo, para repetir la experiencia placentera, generando adicción. Al hacerlo, los mecanismos de recompensa del cerebro se ven afectados, siendo la causa del elevado nivel de dopamina en el organismo. Este aumento anormal del neurotransmisor provoca una respuesta de parte del organismo que radica en disminuir la cantidad de receptores dopaminérgicos. Al hacerlo, la persona adictas sienten menos placer y mas necesidad de consumir sustancias, para alcanzar el mismo efecto de euforia o uno incluso superior.

How does the length of interphase compare to the length of cell division?
Answer:
Usually, cells will take between 5 and 6 hours to complete S phase. G2 is shorter, lasting only 3 to 4 hours in most cells. In sum, then, interphase generally takes between 18 and 20 hours. Mitosis, during which the cell makes preparations for and completes cell division only takes about 2 hours.

3. Spiral galaxies revolve around a single point and gas spinning arms of stars extending from the center
4. Star 4 will stay on the main sequence for the longest time.
Explanation:
A galaxy is a system of gases, dust, and billions of stars and their solar systems, and dark matter which are bound together by gravity. Types of galaxies based on structure are elliptical, spiral, irregular and barred spiral.
Spiral galaxies have a spiral shape consisting of a central bulge, a halo, a disk, and spiral arms. At the center of revolution of the galaxy is the bulge which contains older stars. The disk contains gas, dust and younger stars which extend as spiral arms. The halo is found around the bulge and contains old cluster of stars. Ab example of a spiral galaxy is our Milky Way galaxy.
4. The mass of a star is related to its luminosity as well as its position on the main sequence. High solar mass stars have high luminosity and therefore spend the least time on the main sequence whereas low solar mass stars have low luminosity and spend the most time on the main sequence.
Therefore, Star 4 having the lowest solar mass will spend the most time on the main sequence.
