Answer:
Earthworms need oxygen just like humans, but they don't have lungs like we do. They have a special skin that allows them to “breathe” oxygen right through it. ... This means the amount of oxygen inside the earthworm will always be less (lower concentration) than the area outside of the earthworm (higher concentration).

what is the function of mitrochondria
Answer: Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
Explanation:
Answer: The mitochondrionis a double membrane-bound organelle found in most eukaryotic organisms. Some cells in some multicellular organisms lack mitochondria (for example, mature mammalian red blood cells). A number of unicellular organisms, such as microsporidia, parabasalids, and diplomonads, have reduced or transformed their mitochondria into other structures.

What size molecules can pass through a cell membrane by a process called passive transport?
Answer:
diffusion and osmosis
Explanation:
lipid_ soluble substance
through lipid baleyer
through protein channel
Transported proteins carry small substances like water, amino acids, and charged ions. One to fifteen angstroms is the range in molecule size that can pass through the membrane. The easier it is for a molecule to move across the cell membrane, the smaller it is.
What is cell membrane ?All cells have a cell membrane, also known as a plasma membrane, which separates the interior of the cell from the external environment. A semipermeable lipid bilayer makes up the cell membrane. The movement of materials into and out of the cell is controlled by the cell membrane.
Small molecules or ions can traverse the cell membrane passively without the cell providing any energy. The three basic types of passive transport are osmosis, assisted diffusion, and diffusion.
Gases like oxygen and carbon dioxide, as well as small hydrophobic compounds, quickly traverse membranes. Water and ethanol are examples of small polar molecules that can move across membranes, though more slowly.
Thus, The easier it is for a molecule to move across the cell membrane, the smaller it is.

In the seventeenth century, Francesco Redi performed experiments using raw meat placed in jars.
• Half of the jars were covered, and half were left open,
• Redi noticed that the meat in the sealed jars did not have maggots, but the meat in the open jars did have maggots.
Redi concluded that only flies could make more flies,
.
Which part of the cell theory corresponds to Redi's findings?
Answer: B
Explanation:
''New cells come from the existing cells'' is a part of the cell theory which corresponds to Redi's findings.
Experiment performed by Francesco RediFrancesco Redi conducted an experiment in which he showed that living organisms come from other living organisms. This worked combine with the work of other later scientists, helped to develop the third part of the cell theory which is cells come from other living cells.

Answer:
Look down!!! ;)
Explanation:
In a human karyotype, autosomes or “body chromosomes” (all of the non–sex chromosomes) are generally organized in approximate order of size from largest (chromosome 1) to smallest (chromosome 22). However, chromosome 21 is actually shorter than chromosome 22.

What is one way during the G0 phase that a mistake during the cell cycle could result in problens for the G0 phase?
The G0 phase (G sub zero) or the zero of G is a period of the cell in which it remains in a vegetative state.This phase is related to the "Post-Mitotic" state because they are in a non-dividing phase outside of the cell cycle.
Which muscle cells are often considered as G0 phase cells?Poly-nucleated muscle cells that do not undergo cytokinesis are often considered G0 phase cells.The G0 phase is seen as a distinct and quiet stage that occurs outside the cell cycle.
Mitosis is the procedure with the aid of which a mobile replicates its chromosomes after which segregates them, producing two identical nuclei in training for mobile division. Mitosis is generally followed by way of same department of the mobile's content material into daughter cells that have identical genomes.
The two phases of cell cycle are interphase in which DNA replication occurs, 3 stages of interphase are: G1 phase, S phase and G2 phase and mitotic in which division occurs phase. Mitosis occurs after the completion of DNA replication and doubling of chromosome number and cell contents and after mitosis, two daughter cells are produced of equal number of chromosomes.
Therefore, The G0 phase (G sub zero) or the zero of G is a period of the cell in which it remains in a vegetative state.This phase is related to the "Post-Mitotic" state because they are in a non-dividing phase outside of the cell cycle.

Why does DNA need to make a transcript of itself and what is this transcript called?
Answer:
DNA needs to be transcribed itself as a mechanism for the multiplication of its molecules, and this transcription process is called DNA replication.
Explanation:
DNA replication is a mechanism that allows it, from one molecule, to obtain two molecules identical to the original. In other words, it transcribes the information from one of its strands to a new strand.
The process of DNA replication is semi-conservative, because each new molecule is formed by an original strand and a new strand, which contributes to maintaining the integrity of the genetic information.
As a requirement of the cell division process, as mitosis, DNA must replicate so that each daughter cell has the same genetic information as the original cell. This is why replication of this nucleic acid occurs.

Why are the rocks on the bottom folded but the top ones are not? What could’ve caused this?
Answer: The basic answer could be because of the tectonics plates.
Explanation: Because when two forces act towards each other from opposite sides, rock layers are bent into folds.
Typically, sedimentary rocks are arranged in layers, one on top of the other, the oldest items are listed last, followed by the youngest, this is the concept of "superposition.
Why are rocks folded?Erosion has removed the top layers of the rocks, resulting in the formation of valleys and hills, the top layer might be penetrated with sufficient power. The plates might shift due to erosion, and plate movement.
Many of the stratified rocks, however, are no longer horizontal, we know that sedimentary rocks that are not horizontal either were created in unique ways.
Therefore, more frequently, were shifted from their horizontal position by subsequent processes, such as tilting during episodes of mountain construction, thanks to the Law of Original Horizontality.

Which best describes the relationship between DNA, genes, and chromosomes?
DNA are segments of genes that form tight coils called chromosomes.
Genes are segments of DNA that form tight coils called chromosomes.
Chromosomes are segments of DNA that form tight coils called genes.
Genes are segments of chromosomes that form tight coils called DNA.
Answer:
genes are segments of chromosomes that form tight coils called dna
The statement that best describes the relationship between DNA, genes, and chromosomes is as follows:
Genes are segments of chromosomes that form tight coils called DNA.Thus, the correct option is D.
What is Chromosome?A Chromosome may be defined as a thin thread-like structure that appears during the process of cell division. Such types of thread-like structures are significantly present in the nucleus of the cell.
Chromosomes are made up of DNA, RNA, histones, and some non-histone proteins. Chromosomes were first discovered by E. Strausburger in 1875.
Genes are small stretches that significantly considered the segments of chromosomes. Together they form a tightly coiled structure remarkably known as DNA. Genes carry nucleotide sequences that can produce functional enzymes or proteins.
All such parts carry genetic information with respect to the existence of organisms on the basis of morphology and function.
Therefore, the correct option for this question is D.
