Where in your body do you think cell division is occurring?
Answer:
Everywhere except in gonad cellsExplanation:
Cell division by mitosis occurs in all human body cells except the gonads (sex cells). During mitosis, the DNA is exactly copied and a new daughter cell created with the same number of chromosomes as the parent cell, ie 46. In the sex cells, meiosis occurs where the DNA is halved and the daughter cell has only 23 chromosomes.

and no membrane bound organelles, as mitochondria and chloroplasts,
then it is classified as *
A.Eukaryote
B.Prokaryote
C.Endosymbiosis
D.both a and b
Answer:
B. Prokaryote
Explanation:
Because it does not have a well defined nucleus and bound organelles
Answer:
B
Explanation:
A prokaryotic cell is a simple, single-celled (unicellular) organism that lacks a nucleus, or any other membrane-bound organelle.In prokaryotes, the DNA (chromosome) is in contact with the cellular cytoplasm and is not in a housed membrane-bound nucleus. ... Throughout the course of evolution, organelles such as mitochondria and chloroplasts (a form of plastid) may have arisen from engulfed prokaryotes.

State TWO reasons why enzymes are referred to as 'biological catalysts'.
Answer:
Like all other catalysts, enzymes are characterized by two fundamental properties. First, they increase the rate of chemical reactions without themselves being consumed or permanently altered by the reaction. Second, they increase reaction rates without altering the chemical equilibrium between reactants and products.

what is Soil erosion..?
Explanation: Soil erosion is a gradual process that occurs when the impact of water or wind detaches and removes soil particles, causing the soil to deteriorate. ... The impact of soil erosion on water quality becomes significant, particularly as soil surface runoff. Sediment production and soil erosion are closely related.
what is the approximate percentage of total fixed nitrogen attributed to human activities?
Of the annual global total of fixed nitrogen, human activities account for roughly 45%.
Nitrogen fixation is the global amount of nitrogen that gets assimilated by any living organism into another organic compound. The organic compound can be ammonia or nitrogen ions.
Of the total global annual nitrogen fixation, humans account for a great amount. The current estimation is that humans cause 45% of the nitrogen fixation annually. The leading causes of this high rate are the burning of fossil fuels and increased agricultural fertilizer use.

how does oxygen have a direct effect on sea urchins
Answer:
When the oxygen level is low in a Purple Sea Urchin, muscles associated with Aristotle's Lantern pump fluid through its body (through the canals). Carbon dioxide (waste/not good stuff) is released through the anus. The Purple Sea Urchin obtains oxygen through diffusion only (the diffusion of oxygen into the organism).
Explanation:
Brainliest please
Sea urchins breathe through their feet tubes because of nonavailability of lungs and gills in them. When the oxygen level is low at that time, the sea urchins pump fluids through their anus.
How are sea urchins able to survive sea ?Sea urchins are able to survive in sea because of the tiny hair called spines present on their body as water currents are created because of the hair and waste gets washed away with the water currents created.
When the carbon dioxide level gets increased in the sea at that time the skeletal structures of the marine animals are also affected.
The shells made up of calcium also gets affected because of the increasing acidity in the water. Carbon dioxide not so good is released through the anus and this totally affects the normal regulation of the creature.

what is the last structure of the air passageway in your lungs
Answer:
Bronchioles
Explanation:
You inhale through your nose and the air is filtered. It goes down the pharynx. It goes through the larynx. A "door" called the epiglottis opens during breathing. Then it enters the trachea. (windpipe) It goes through the bronchus. The tertiary bronchi branch into fine tubules called bronchioles, the last passageways for air. Air ends its pathway in the ________. (I bet you can guess because you're so smart!) They're surrounded by capillaries that connect the pulmonary arteries and veins. This enables the transfer of oxygen and carbon dioxide.

Which of the following statements are FALSE? A. Meiosis separates homologous chromosomes in a diploid cell to produce haploid daughter cells containing one copy of each type of chromosome. B. During prophase I, homologous chromosomes pair up and exchange DNA. C. During meiosis II, paired homologous chromosomes move up to the equator of the cell. D. During anaphase I, homologous chromosomes separate. E. In meiosis II, the sister chromatids of each chromosome separate. F. In meiosis I, ploidy is reduced. G. In meiosis II, ploidy is reduced. H. During anaphase I, sister chromatids separate.
The statements about meiosis that are false include the following:
C. During meiosis II, paired homologous chromosomes move up to the equator of the cell.
G. In meiosis II, ploidy is reduced.
H. During anaphase I, sister chromatids separate.
Meiosis can be defined as a type of cell division or duplication that occurs in all body cells found in living organisms, through which a single cell divides twice to produce four (4) haploid cells (gamete).
During cell division, deoxyribonucleic acid (DNA) must be replicated before meiosis can take place in any body cell found in living organisms.
Generally, the phases or steps that occur during meiosis include:
Prophase I.Metaphase I.Anaphase I.Telophase I.Prophase II.Metaphase II.Anaphase II.Telophase II.Furthermore, the statements about meiosis that are false include the following:
1. During meiosis II, paired homologous chromosomes move up to the equator of the cell.
The movement of paired homologous chromosomes to the equator of the cell takes place during prophase II.2. In meiosis II, ploidy is reduced.
Actually, it is meiosis I that reduces ploidy.3. During anaphase I, sister chromatids separate.
Sister chromatids are separated during anaphase II.Read more: https://brainly.com/question/12103012
21. Three different processes are occurring in the drawing below. Name each process and describe it.
The three different processes that are occurring in the above drawing are:
1. Process A: Diffusion.
2. Process B: Facilitated diffusion.
3. Process C: Active transport.
Cell transport refers to the movement of ions, molecules, or substances across the cell membrane, either into or out of the cells of a living organism.
From the above diagram, the three (3) different processes that are occurring are:
1. Process A: Diffusion.
Diffusion refers to the movement of gas molecules from a region of high concentration (top) to a region of lower concentration (bottom) until an equilibrium is attained or reached.2. Process B: Facilitated diffusion.
Facilitated diffusion refers to the movement of substances or gas molecules across a cell membrane from a region of high concentration (top) to a region of lower concentration (bottom), especially through the help of transport protein.3. Process C: Active transport.
Active transport involves the movement of substances across the cell membrane from a region of lower concentration to a region of higher concentration, against a concentration gradient and in the presence of oxygen.Read more: https://brainly.com/question/18646362
which of the following is a true statement about glycolysis?
A. electrons and hydrogens get transferred to NAD+, making NADH
B. Electrons and hydrogens get removed from glucose when it gets oxidized
C. ATP gets made when a phosphate is transferred to ADP
D. ALL OF THE ABOVE
All the options are true statements regarding the glycolysis and its mode of
operation.
Glycolysis involves the breakdown of glucose in order to release energy.
This produces pyruvate, two hydrogen ions , two molecules of water and
the free energy is used to produce ATP
In glycolysis, electrons and hydrogens get removed from glucose when it
gets oxidized and then they get transferred to NAD+, making NADH.
The ATP is generated by the transfer of a phosphate to the ADP to form ATP
which is a source of energy.
