If each of these food chains start with 10,000 grams of phytoplankton, how much reaches the highest trophic level in each food chain
Energy is transferred from one trophic level in a food chain to another. However, not all the energy available at a trophic level is transferred to the next.
Only about 10% of the energy in the lower trophic level gets to the immediate higher trophic level and the rest is lost as metabolic heat.
Thus, if a food chain starts with 10,000 grams of phytoplankton, the quantity that will get to the highest trophic level would depend on the number of intermediate trophic levels in between the lowest and the highest.
For every step the energy is transferred up the trophic level in the food chain, 90% of it is lost.

mention 2 references for Baltimore classification of viruses
Answer:
Baltimore classification is a system used to classify viruses based on their manner of messenger RNA (mRNA) synthesis. By organizing viruses based on their manner of mRNA production, it is possible to study viruses that behave similarly as a distinct group.
Answer:
Baltimore classification is a system used to classify viruses based on their manner of messenger RNA (mRNA) synthesis. By organizing viruses based on their manner of mRNA production, it is possible to study viruses that behave similarly as a distinct group. Seven Baltimore groups are described that take into consideration whether the viral genome is made of deoxyribonucleic acid (DNA) or ribonucleic acid (RNA), whether the genome is single- or double-stranded, and whether the sense of a single-stranded RNA genome is positive or negative.

Which is NOT
involved with an
inflammatory
response?
A. fever - increased temperature
B. slowed blood flow
C. white blood cells move to the area of infection
D. inflammation in area
Out of the given answers B. slowed blood flow is not involved with an inflammatory response.
During an inflammatory response, several physiological changes occur in the body to combat infection or injury. Let's briefly discuss the other options to understand their involvement in the inflammatory response:
A. Fever - increased temperature: Fever is a common feature of an inflammatory response. It is caused by the release of certain chemicals called pyrogens that act on the hypothalamus in the brain, raising the body's temperature. The increased temperature helps to enhance the immune response and inhibit the growth of certain pathogens.
C. White blood cells move to the area of infection: Inflammation triggers the recruitment of white blood cells, such as neutrophils and macrophages, to the site of infection or injury. These immune cells play a crucial role in identifying and eliminating pathogens, as well as removing damaged tissue and promoting tissue repair.
D. Inflammation in the area: Inflammation is a hallmark of the inflammatory response. It involves localized redness, swelling, heat, and pain at the site of infection or injury. Inflammation helps to isolate the area, prevent the spread of infection, and promote healing.
B. Slowed blood flow: Slowed blood flow is not a characteristic of the inflammatory response. On the contrary, inflammation often leads to increased blood flow in the affected area, resulting in redness and heat. The increased blood flow facilitates the delivery of immune cells, oxygen, and nutrients to the site, aiding in the immune response and tissue repair.
In conclusion, slowed blood flow is not involved in the inflammatory response, while the other options (fever, white blood cell recruitment, and inflammation) are key components of the inflammatory process. Therefore, the correct answer is B.

Explain what happens in each stage of mitosis.
no links
Answer:
Stage #1 Prophase: Chromatin fibers become coiled into chromosomes, with each chromosome having two chromatids joined at a centromere.
The mitotic spindle, composed of microtubules and proteins, forms in the cytoplasm.
The two pairs of centrioles (formed from the replication of one pair in Interphase) move away from one another toward opposite ends of the cell due to the lengthening of the microtubules that form between them.
Polar fibers, which are microtubules that make up the spindle fibers, reach from each cell pole to the cell's equator.
Kinetochores, which are specialized regions in the centromeres of chromosomes, attach to a type of microtubule called kinetochore fibers.
The kinetochore fibers "interact" with the spindle polar fibers connecting the kinetochores to the polar fibers.
The chromosomes begin to migrate toward the cell center.
Stage #2 Metaphase: The nuclear membrane disappears completely.
Polar fibers (microtubules that make up the spindle fibers) continue to extend from the poles to the center of the cell.
Chromosomes move randomly until they attach (at their kinetochores) to polar fibers from both sides of their centromeres.
Chromosomes align at the metaphase plate at right angles to the spindle poles.
Chromosomes are held at the metaphase plate by the equal forces of the polar fibers pushing on the centromeres of the chromosomes.
Stage #3: Anaphase: The paired centromeres in each distinct chromosome begin to move apart.
Once the paired sister chromatids separate from one another, each is considered a "full" chromosome. They are referred to as daughter chromosomes.
Through the spindle apparatus, the daughter chromosomes move to the poles at opposite ends of the cell.
The daughter chromosomes migrate centromere first and the kinetochore fibers become shorter as the chromosomes near a pole.
In preparation for telophase, the two cell poles also move further apart during the course of anaphase. At the end of anaphase, each pole contains a complete compilation of chromosomes.
Stage #4 Telophase: The polar fibers continue to lengthen.
Nuclei begin to form at opposite poles.
The nuclear envelopes of these nuclei form from remnant pieces of the parent cell's nuclear envelope and from pieces of the endomembrane system.
Nucleoli also reappear.
Chromatin fibers of chromosomes uncoil.
After these changes, telophase/mitosis is largely complete. The genetic contents of one cell have been divided equally into two.
Stage #5 Cytokinesis: Cytokinesis is the division of the cell's cytoplasm. It begins prior to the end of mitosis in anaphase and completes shortly after telophase/mitosis. At the end of cytokinesis, two genetically identical daughter cells are produced. These are diploid cells, with each cell containing a full complement of chromosomes.
Cells produced through mitosis are different from those produced through meiosis. In meiosis, four daughter cells are produced. These cells are haploid cells, containing one-half the number of chromosomes as the original cell. Sex cells undergo meiosis. When sex cells unite during fertilization, these haploid cells become a diploid cell.

which of the following statements best describes nucleic acids?
Answer:
Large nitrogen-containing polymers found mainly in cell nuclei
Explanation:
The statement that best describes nucleic acids is that they are large nitrogen-containing polymers found mainly in cell nuclei, which is present in Option A. Nucleic acid includes both the DNA and the RNA, and in eukaryotes, these are found in the nucleus.
What is nucleic acid?The nucleic acid consists of DNA and RNA, which are made up of nucleotides, each of which is composed of a sugar, either deoxyribose sugar (DNA) or ribose sugar (RNA), phosphate, and a nitrogen base. In humans and other eukaryotes, DNA and RNA are present in the nucleus. In the human cell, the DNA is double helical, with hydrogen bonds connecting the strands.
While RNA is a single chain, the majority of it does not form a double helix. Nucleic acids carry out the gene expression present in the cell.

between the left & right
sides of a heart?
Answer:
See explanation section for answer:
Explanation:
The left side of the heart contains the left atrium which allows oxygen rich blood to flow through the mitral valve and into the left ventricle. Whereas the right side of the heart contains the right atrium which allows the blood with poor oxygen levels to enter the right ventricle through the tricuspid valve.
Also, the left ventricle is larger than the right ventricle because the left ventricle is responsible for pumping the fresh oxygen rich blood throughout the body.
