Hope this helped and pls mark me brainliest
The statement that says "Chromosomes are strands of DNA, tightly wrapped up, that are located in the nucleus" is correct regarding chromosomes.
Chromosomes are the highly organized structures inside biological cells, made up of DNA and other proteins, and where most of an individual's genetic information resides.
Chromosomes have a double structure, composed of two structures parallel to each other and joined by a centromere, called chromatids.
In eukaryotic cells (with a defined nucleus), the chromosomes are elongated and found in the nucleus, while in prokaryotic cells, such as bacteria, these appear as circular rings closed in the nucleoid.
The chromosome allows the DNA information to be conserved and evenly distributed.
Therefore, we can conclude that chromosomes are condensed strands or rings of DNA and are located in the nucleus of cells when they are not dividing.

DNA polymerase checks the DNA for errors and there are no complementary base pairs in DNA (Options B and C). It helps to prevent errors during DNA replication.
What is DNA replication?DNA replication refers to the cellular process aimed at generating two identical molecules of DNA during cell division.
DNA replication is a fundamental mechanism to sure the perpetuity of genetic material (i.e., the inheritance of genetic material).
During DNA replication, most DNA polymerases check the DNA for errors, repairing errors in a mechanism known as DNA proofreading.

The optical microscope is regularly used to identify bacteria and viruses. In 1918 the Spanish Flu infected almost one third of the world and was thought to be caused by bacteria. However, a virulent virus was the cause of the Spanish Flu. From what we have learned throughout this lab on microscopy, why weren't scientists able to identify the Spanish Flu with a microscope?
Answers
Answer:
In 1918, one of the deadliest pandemics in history took place, known as the Spanish flu. The flu infected almost 500 million individuals globally, that is, about 33 percent of the world's population. Due to the Spanish flu, the death of about 20 to 50 million people took place.
The general symptoms of the first wave of Spanish flu were fever, chills, and fatigue. However, during the second wave, the people started to die within hours after the development of the signs, due to the development of a fluid taking place within the lungs resulting in suffocation.
At the time of the Spanish flu pandemic, not much was known regarding the composition of the virus. The scientists at that time were not able to make a difference between a bacteria and a virus. This made it tough for scientists to determine the Spanish flu with the help of a microscope.

° label the molten material found at point B. ______
Answers
Answer:
ANSWER:
Explanation:
A magma
B lava
The material labelled in the molten material which is found at point A is magma and the one labelled in the molten material found at point B is lava.
What is the difference between magma and lava?Magma is the molten or semi-molten natural material from which all the igneous rocks are formed on the Earth. Magma is found beneath the surface of the Earth, and the evidence of magmatism has also been discovered on the other terrestrial planets and some of the natural satellites as well. Besides the molten rock, magma may also contain some suspended crystals and gas bubbles in it.
Lava is the molten or partially molten rock which has been expelled out from the interior of a terrestrial planet such as the Earth. Lava may be erupted at a volcano or through a fracture in the Earth's crust, on land or under the water, usually at the temperature ranges from 800 to 1,200°C. The volcanic rock resulting from the subsequent cooling of the material is also often called lava.

Four o'clock plants can have green leaves, white leaves, or variegated leaves (leaves with areas of white and areas of green). The white regions of the leaves lack functioning chloroplasts. The transmission of leaf color in four o'clock plants demonstrates organelle inheritance. In this problem, you will explore this inheritance pattern. Which of the following crosses between four o'clock plants could produce progeny plants with green leaves?
1. G variegated (female) x variegated (male)
2. G green (female) x white (male)
3. G white (female) x green (male)
4. G white (female) x variegated (male)
5. Gvariegated (female) x white (male)
Answers
Answer:
2. G green (female) x white (male)
Explanation:
The cross that could produce progeny plants with green leaves would be the cross between a green female and a white male.
Since the transmission of leaf color in the plant demonstrates organelle inheritance, the female controls which leaf color is inherited by the progeny. Organelles are generally located in the cytoplasm which is largely contributed by the female egg during fertilization. Hence, organelle inheritance are controlled by the female and that is why they are often referred to as maternal inheritance.
Therefore, a cross involving a green female and a white male would largely yield green progeny provided that the trait inheritance follows an organelle inheritance.

With respect to mammalian cell culture, which of the following statements is true? During the establishment of a cell line, senescence is the last stage of the cell's life. Rodent cells cultures undergo spontaneous transformation with similar frequency to human cell cultures. Media used for cell growth contain proteases and a divalent cation chelator to help cells adhere to the surface. Embryonic cell lines do not undergo senescence nor do they have a finite life span.
Answers
Answer:
Media used for cell growth contain proteases and a divalent cation chelator to help cells adhere to the surface.
Explanation:
Mammalian cell structure is the process where animals cells are grow in vitro in a flask or dish. The methods, equipments, reagents and supplies use in this type of culture prevent contamination and maintain cell culture purity. Protein enzymes like Serine protease breaks the cellular matrics interaction between the cells. In cell culture, the focal adhesions that are anchoring the cell to the culture dish is cut away. Most trypsin solutions for cell culture also contain EDTA which acts as a chelator for calcium. When calcium is remove from a solution, cadehrin that hold cells to each other break down and cells become separated from each other.

Light energy, above the arrow
Chlorophyll,to the left of the arrow
Enzymes, to the left of the arrow
ATP, above the arrow
Answers
Answer:
The question is incomplete. The remaining fragment that completes the question is: "What more must be added to the chemical equation to accurately represent photosynthesis? "
The answer is Light energy, above the arrow
Explanation:
Photosynthesis is a metabolic reaction unique to autotrophic organisms like plants, algae etc. It is the process whereby these organisms produce their food (glucose) using light energy from the sun.
Photosynthesis cannot occur without light, as the name implies: Photo- meaning light. The sun is the source of this light energy, which photosynthetic organisms like plants capture using a green pigment called CHLOROPHYLL.
Photosynthesis is a reaction with a general equation:
6CO2 + 6H2O ---light energy-----> C6H12O6 + 6O2
However, the energy needed to perform this reaction comes from light provided by the sun. Hence, Naval needs to put LIGHT above the arrow in her equation in order to accurately represent photosynthesis.
This nutrient is cycled between living things and the soil. Plants absorb this nutrient from the soil and turn it into organic compounds through assimilation. Animals eats the plants and pass the nutrient through the food chain from one organism to another. When the animal dies, it decomposes and returns the nutrient back to the soil. The nutrient can also enter the soil through weathering and erosion.
