Answer:
DNA is the recipe for how to build your body's proteins and mRNA is an index card it copies the DNA but doesn't have to stay in the nucleus. (1st option)
Explanation:
DNA carries genetic instructions for developing, growing and reproducing all known organisms and many viruses. mRNA, on the other hand, collects the DNA's instruction to the cells' protein-making part.

What happens when two haploid
gametes are combined during
fertilization?
A. The cell doubles in size.
B. The diploid number is restored to the zygote.
C. The cell immediately fuses to any cell any the
vicinity
Answers
Answer:
Option B is the correct one
Explanation:
Fertilization between the haploid gametes forms a diploid zygote. ... Haploid (1n) spores germinate and undergo mitosis to produce a multicellular gametophyte (1n). Specialized cells of the gametophyte undergo mitosis to produce sperm and egg cells (1n), which combine in fertilization to make a zygote (2n)

Answers
Answer:
The correct answer is ''post-zygotic barrier to reproduction''
Explanation:
Biological barriers prevent the exchange of genes between two or more populations, a postzygotic reproductive barrier reduces the survival or reproduction of hybrid offspring. In hybrid non-viability there is low survival of the hybrid, especially during embryonic stages. On the other hand, the sterility of the hybrid occurs when the fertilized egg develops into a healthy but sterile adult. Segregation of aneuploid gametes during meiosis, different gene associations occur on the chromosomes of the parents.

Explique de qué manera la deriva continental ha influido en la distribución de especies vegetales y animales en el mundo.
Answers
Answer:
la deriva continental ha notablemente influido en la distribución actual de las especies. Este fenómeno se puede observar en grupos de organismos similares que se encuentran en diferentes continentes, lo cual concuerda con la idea de que la separación entre dichos continentes se produjo más tardíamente en el tiempo
Explanation:
La teoría de la deriva continental plantea que durante el final del Paleozoico y el principio del Mesozoico (hace aproximadamente hace 225 millones de años) las masas continentales actuales se encontraban unidas formando una gran masa de tierra o supercontinente conocido como 'Pangea'. Esta teoría se basa en evidencia de diversa fuentes incluyendo pruebas geográficas (coincidencias en las costas de algunos continentes), paleontológicas (mismos fósiles en diferentes continentes), geológicas y tectónicas (por ej., la presencia de cadenas montañosas que se separaron hace millones de años), y paleoclimáticas (evidencia de climas similares durante el pasado en continentes diferentes). La deriva contiental afectó la distribución actual de especies de plantas y animales. Por ejemplo, la fauna en Europa es semejante a la observada en Norteamérica porque estos continentes se separaron más tardíamente en el tiempo que otros contientes/masas de tierra del hemisferio sur, y dichas semejanzas se encuentran reflejadas en organismos evolutivamente más relacionados (menor tiempo de divergencia evolutiva).

Which of the following conclusions is most likely true if a region experiences unusually low daily temperatures for the season?
the seasonal total of GDD units will be lower than average
the accumulated GDD units still needed to ripen a crop will fall
the average daily value of the GDD will rise
the Tbase value for a particular crop will rise
Answers
Answer: D
Explanation: Because if it is going to be cold out every day, the plants aren't gonna grow. So that means the crop rarity will go up, and people would take advantage, and sell them for more of a value.

Answers
Answer:
Explanation:
Taxol will be effective because it stops the uncontrollable cell division of cancerous cells. It makes it very difficult for cells form mitotic spindles and hence will make it very hard for the DNA to be divided. This will then stop division and causes it to die.

This situation is an example of 'ecosystems are ALTERED through the activities of humans' (Option 2).
Human activities (i.e., anthropogenic activities) represent the main factor capable of affecting the homeostasis of the ecosystems.Some human activities that negatively alter a natural ecosystem include deforestation for different purposes (e.g., urbanization, agriculture, etc), the introduction of non-native invasive species, pollution, etc.These activities may trigger serious problems to the environment such as soil erosion, climate change, undrinkable water, etc.In conclusion, this situation is an example of 'ecosystems are ALTERED through the activities of humans'.

What happens to waste before it is passed out of the body???

Answer:
It goes through a series of "Events" I'll talk you through them lol.
Explanation:
See, when you eat something it goes down the esophagus and into the stomach, then to your small and large intestine. While it slowly travels through your intestines, your body is slowly taking the nutrients from that piece of food, which makes the food turn into a different color, since all the nutrients is taken out of the food, then the body no longer needs that food. Then it disposes from the body!

If a microscope has a 40´ objective lens in place and a 15´ ocular lens, the total magnification of the microscope system under these conditions is
Answers
Answer:
600`
Explanation:
The total magnification of a microscope is obtained by multiplying the magnifying power of the ocular lens and that of the objective lens.
Mathematically.
Total magnification = ocular magnification x objective magnification
In this case, ocular magnification = 40`, objective magnification = 15`
Total magnification of the microscope system = 40 x 15
= 600`
Hence, the microscope system under these conditions would be 600`.
