How does the body maintain blood sugar levels? your own words
Answer:
When the body does not convert enough glucose, blood sugar levels remain high. Insulin helps the cells absorb glucose, reducing blood sugar and providing the cells with glucose for energy. When blood sugar levels are too low, the pancreas releases glucagon.

Which pair of structures would provide a positive identification of an animal cell under a microscope?
flagellum, lysosome
nucleus, mitochondrion
ribosome, cell wall
chromatin, chloroplast
flagellum, lysosome: Both of these are found in animal cells, but the real difference is flagellum is ONLY found in animal cells
nucleus, mitochondrion: Both of these are found in Animal cells X
ribosome, cell wall: Cell wall is only in plants X
chromatin, chloroplast: Chloroplast is only found in plant cells X
Explanation:
Firstly cell wall and chloroplasts can only be found in plant cells and will not appear in an animal cell.
Flagellum usually appears in many bacteria (microorganism) and only a few animal cells. Most animal cells do not have flagellum.
However animal cells do have a nucleus which contains important genetic material such as DNA and mitochondrion which creates energy for the cell to use for metabolism inside the cell. (Even though most eukaryote cells have these 2 organelles)
Between the 1st and 2nd options, none of them is exactly correct. But nucleus and mitochondria are more widely found in various types of cells (plants, etc.)
I would choose the 1st option as the best answer here because it is more detailed.

8. What is one similarity between human skeletal muscles and some bacteria?
A. Both carry out autotrophic nutrition when food becomes scarce in the environment,
B. Both produce lactic acid when oxygen is not available for respiration.
C. Both reproduce asexually, using binary fission and regeneration.
D. Both lack a nuclear membrane surrounding the chromosomes.
Answer: B
Explanation:
Human skeletal muscles and some bacteria both produce lactic acid when oxygen is not available for respiration, which is similar. The best choice is B.
What are skeletal muscles?Skeletal muscles enable humans to move and perform daily activities. They are essential to breathing mechanics and help preserve balance and posture. They also protect the vital organs of the body.
Skeletal muscle fibers can be found in muscles that are attached to bones. They are consciously regulated and have a striated appearance.
Lack of oxygen causes both skeletal muscle and bacteria to produce lactic acid through respiration.
Since both produce lactic acid when oxygen isn't available for respiration, option B is the proper response.

Cathy's favorite salad dressing is a liquid with particles of salt, pepper, and garlic. When comparing a spoonful of salad dressing to a cell, what would the liquid be equivalent to? What would the particles be equivalent to?
Answer:
Liquid equivalent to "cytoplasm" and the particles equivalent to "organelles".
Explanation:
While comparing a liquid salad dressing to a cell, the liquid will be equivalent to "cytoplasm" because cytoplasm is a thick solution present in each cell that made up of water, salts, and proteins.
The particles would be equivalent to "organelles" because as particles float in liquid salad adding flavours to the salad likewise organelles are present in a cell floating in the cytoplasm that performs a specific function.
Hence, the correct answer is " liquid will be equivalent to "cytoplasm" and the particles will be equal to "organelles".
What happened? A corpse is discovered in an enclosed room, there are no open windows, yet blowfly larva (stage 2) are found on the body. What does this tell you about the corpse?
Answer:
The corpse was deposited into the room from somewhere else
Explanation:
The larva could not have spontaneously emerged from the corpse if the blowfly had not somehow perched and laid its egg on it. Since there are no open windows, and perhaps, other openings to the room; the only plausible explanation for the emergence of the blowfly larva would be that the corpse was deposited into the room from somewhere else. From the initial location, the blowfly had perched and laid its egg on the body and the eggs only hatched while in the enclosed room.
The corpse changed into deposited into the room from someplace else as the larva couldn't have spontaneously emerged from the corpse if the blowfly had now no longer in some way perched and laid its egg on it.
Since there aren't any open windows, and perhaps, different openings to the room; the best potential cause of the emergence of the blowfly larva might be that the corpse changed into deposited into the room from someplace else. From the preliminary location, the blowfly had perched and laid its egg at the frame and the eggs best hatched even as withinside the enclosed room.
What are larvae?Larvae are the caterpillars and worms that has some kind of grubs and maggots. It usually lives inside the mud.

It is advantageous for a predator to prey exclusively on a single prey species.
Answer:
Assuming this is a true/false question, the answer would be false.
If a predator only preyed on one species, it would be at a disadvantage if the prey it feeds on gets wiped out in that region.
Therefore, your answer is False.
Pls answer its due soon!!!
Explanation:
Meiosis makes genetic variety possible. It makes sperm & egg cells called gametes. Each gamete has 23 chromosomes. To make a diploid cell two gametes (sperm & cell) come together.
During prophase 1 the chromosomes pair up with their homologous pairs so they can transfer their genetic information and exchange it between each other. It makes recombinant chromosomes that influence the genetic diversity between the same people.
Now they are in metaphase 1, the chromosomes are in pairs in the middle of the cell. In anaphase 1, the chromosomes are pulled away by the spindle fibers. Then in telophase 1, there are two formed nuclei. Cytokinesis 1 then splits the cytoplasm.
Now they are in meiosis 2. During prophase 2, there are chromosomes and the spindles are starting to form again without crossing over like in prophase 1. In metaphase 2, chromosomes are going to line up in the middle in both cells unlike during metaphase 1 where the chromosomes were only in pairs. In anaphase 2, only the chromatids are being pulled away by the spindle fibers. Next in telophase 2 the nuclei reform and the 2 cells are each going to divide into 4 cells. Finally, cytokinesis completely splits the cytoplasm.
Keeping in mind that each sex only produces one type of gamete cell (sperm or eggs), and of the independent assortment and crossing over of chromosomes, the end result will be diversity.
What are the locations and end products for the processes of transcription and
translation?
The cytoplasm is the site of translation, the next process that converts a gene into a protein. In order to “read” the sequence of mRNA nucleotides, the ribosome, a specialized complex, interacts with the messenger RNA.
What is role of gene expression in an organism?It serves as both a volume control that raises or lowers the level of proteins produced, and an on/off switch to regulate when proteins are created.
Because a particular protein can only be made when its gene is turned on, gene expression is significant.
But the process of turning a gene into a protein involves numerous steps, and one of these phases—the production of proteins—is essential for the gene expression pathway that can be altered in cancer.
Therefore, transcription occur at nucleus and translation take place in cytoplasm.

How many different ways can the 23 homologous pairs in a human germ cell arrange themselves during Metaphase I?
Answer:
eight million
Explanation:
Eight million different ways can the 23 homologous pairs in a human germ cell.
What is Homologous pairs?One of a pair of chromosomes with the same gene sequence, locations, chromosomal length, and centromere placement is referred to as a homologous chromosome. One paternal and one maternal chromosome make up a homologous pair.
A somatic cell of a human has a total of 46 chromosomes in its nucleus. The father inherits half of them (22 autosomes Plus X or Y chromosome), while the mother inherits the other half (22 autosomes + X chromosome).
A female typically has 23 homologous chromosomes, compared to a male's 22. This is due to the fact that men' X and Y sex chromosomes are not identical. During meiosis, homologous chromosomal pairing is crucial.
Therefore, Eight million different ways can the 23 homologous pairs in a human germ cell.
