A skin cell of a red fox has 34 chromosomes. You look at the cell under a microscope and see that it has 34 chromosomes and one nucleus. Several hours later, you look at the same cell a second time and see that it has double the amount of DNA and one nucleus. A little while later, you see the cell for a third time and notice that it has 68 chromosomes and two nuclei. What stage of the cell cycle was this cell in when you viewed it at each time point
Answer:
See the answer below
Explanation:
At the first look, the cell was in G1 phase of the cell cycle. At the second look, the cell was in the G2 phase of the cell cycle, and at the third look, the cell was in Telophase.
At the G1 phase of the cell cycle, the cell mainly experiences growth and development. Nothing much happens except that the cell increases in volume.
At the G2 phase of the cell cycle, synthesis of DNA has taken place during the S phase and the amount of DNA present in a cell is doubled at this stage.
At the telophase stage of the cell division in the cell cycle, chromosomes have completed their migration to the poles and each pole appears like a nucleus with their individual chromosomes under the microscope. The cytoplasm is yet to divide at this stage, hence, everything still appears as a single cell.

how do each of the following factors affect the productivity in this process of photosynthesis ? 1)Temperature 2) Water 3) carbondioxide
Answer:
without the right amount of temperature and water photosynthesis won't take place and without the presence of carbon dioxide...there is nothing like photosynthesis
Explanation:
1) Temperature- Above 28°C of temperature photosynthesis will not take place faster as necessary. At this temperature, the enzymes responsible for photosynthesis will not work efficient as needed . 2)Water and 3)Carbon Dioxide-Water and carbon dioxide are the reactants in Photosynthesis which means they are taken in to produce energy. Six molecules of water and six molecules of carbon dioxide are needed to break apart glucose and produce energy.

Cómo explicarías tu que el soporte vegetal es más importante que los animales en un ecosistema?
Answer:
Las plantas son productores primarios, mientras que los animales son consumidores
Explanation:
La cadena alimenticia está conformada por niveles tróficos donde la energía fluye desde los niveles basales representados por la base de la pirámide, hasta los niveles superiores (pico de la pirámide). De este modo, los organismos representan diferentes eslabones de acuerdo a su posición en la cadena alimenticia. En el primer nivel se encuentran los productores primarios como lo son, por ejemplo, las plantas y algas de ambientes terrestres y acuáticos, respectivamente, siguiendo por los consumidores primarios (por ejemplo, especies hervívoras), continuando sucesivamente por los consumidores secundarios, terciarios y cuaternarios (especies carnívoras), los cuales se encuentran en posiciones cada vez más altas de la pirámide. No obstante, es importante indicar que existen ocasiones donde los consumidores superiores (ya sea secundarios, terciarios y cuaternarios) se alimentan de especies situadas por debajo de diferentes niveles no consecutivos e incluso también de especies pertenecientes al mismo nivel trófico, con lo cual encajando en más de una categoría y dificultando su clasificación en la cadena.

Which of the following statements is true? Bacteria and protozoa are examples of unicellular organisms. Individual cells do not need to maintain homeostasis. Most multicellular organisms reproduce through mitosis. Two identical daughter cells are created from sexual reproduction.
Answer:
Bacteria and protozoa are examples of unicellular organisms.
Explanation:
Bacteria are prokaryotic organisms in which the genetic material is not enclosed in a membrane. Bacteria are one of the oldest groups on Earth. Bacteria may inhabit diverse environments such as the deep ocean, soils, acidic hot surfaces, radioactive materials, etc. On the other hand, protozoa (also known as protozoan) are unicellular, heterotrophic, eukaryotic microorganisms, whose genetic material is enclosed within a nucleus that has a membrane. This group was originally considered to be animals because they have animal-like features including, for example, motility and predation.
The statement "Bacteria and protozoa are examples of unicellular organisms" is true. Bacteria and protozoa are both single-celled organisms.
What are the false statements?The statement "Individual cells do not need to maintain homeostasis" is false. Homeostasis is the ability of cells to regulate their internal environment to maintain a stable condition necessary for proper functioning.
The statement "Most multicellular organisms reproduce through mitosis" is false. Most multicellular organisms reproduce through a process called meiosis, which involves the formation of specialized cells called gametes.
The statement "Two identical daughter cells are created from sexual reproduction" is false. Sexual reproduction involves the fusion of two gametes, resulting in the formation of a genetically diverse offspring.

How do the leaves help trees survive in their respective biomes? A. The temperate leaves are broad and flat to maximize sunlight absorption, while the taiga leaves are long and thin to minimize sunlight absorption. B. The temperate leaves are thin to minimize absorption of sunlight, while the taiga leaves are specialized to store water during the dry season. C. The temperate leaves shed water during the wet season, while the taiga leaves can enter long periods of dormancy during colder weather. D. The temperate leaves grow in the spring and shed in the cold, while the taiga leaves are dark and wax-coated to prevent the tree from freezing.
Answer:
The correct answer is option D.
Explanation:
The temperate leaves grow in temperate forests found in America, Europe, and Asia. This biome comprise of trees have evergreen conifers with needle like leaves. Such leaves can endure wide change of temperature and light. Some vegetation of temperate biome are conifers such as Pine, Hemlock and other. The trees shed their leaves with the beginning of fall and new leaves are delivered in late-winter to protect from the cold.
On other hand, Taiga forest is the biggest biome on the planet. This biome contain conifers with long, slender waxy needles like leaves. These waxy leaves provide security against freezing temperature and from dying drying out. In contrast to temperate they don't sheds their leaves in winter and keep their needles throughout the entire year.
Thus, the correct answer is option D.
