TRUE/FALSE. different cell types develop in a multicellular organism because each cell has its own unique set of genes.
FALSE. When cells divide, genetic material is transferred to the daughter cells. Through the process of cell division, new cells are created from existing ones. Cells are the basic unit of life.
RNA and protein molecules are synthesized and accumulated by various cell types in multicellular organisms, which causes these cell types to develop differences from one another. They typically carry out this activity without changing the DNA's sequence.
An old set of frog experimentation provides proof that the genome is preserved during cell differentiation. A fully differentiated frog cell's nucleus can direct the recipient egg to develop a typical tadpole when it is injected into a frog egg that has had its nucleus removed (Figure). The differentiated donor cell cannot have lost any significant DNA sequences because the tadpole contains a full range of differentiated cells that derived their DNA sequences from the nucleus of the original donor cell. In experiments using different plants, a similar conclusion was drawn. Here, differentiated plant tissue fragments are placed in culture before being separated into individual cells.

Which of the following describes a common feature of F-actin, microtubules and intermediate filaments? a) filaments are all made of up monomeric subunits b) filaments provide tracks for molecular motors c) filament assembly depends on ATP hydrolysis d) filament assembly depends on GTP hydrolysis e) filaments are all polar structures
Option b is Correct. The fact that filaments serve as tracks for molecular motors is what the next sentence refers to as a characteristic of intermediate filaments, microtubules, and F-actin.
Similar to actin filaments, microtubules are dynamic structures that can quickly expand and contract by the addition or subtraction of tubulin proteins. Microtubules exhibit directionality, which means they have two structurally distinct ends, making them similar to actin filaments in this regard.
For mobility and stability, this structure serves as a skeleton and muscle at the same time. The cytoskeleton's long fibers are polymers of subunits. The cytoskeleton is made up primarily of intermediate filaments, microfilaments, and microtubules. Actin filaments and microtubules are constructed of compact and globular actin subunits, whereas intermediate filaments are composed of smaller, elongated, and fibrous subunits.

after mitosis, _____ is the phase where a cleavage furrow forms along the center of the cell and eventually causes the cell to split.
After mitosis, Cytokinesis is the phase where a cleavage furrow forms along the center of the cell and eventually causes the cell to split.
The physical process of cell division known as cytokinesis separates a parental cell's cytoplasm into two daughter cells. It happens simultaneously with the two nuclear division processes known as meiosis and mitosis that take place in animal cells. Two distinct nuclei are produced during mitosis and each of the two meiotic divisions within a single cell.
In order to divide the cell in half and make sure that each daughter cell has one nucleus, cytokinesis must be performed. Cytokinesis begins at the anaphase phase of nuclear division and lasts all the way through telophase.

Female algae eaters may grow bigger and produce larger and more numerous broods.
The larger size of the female algae eaters is a conspicuous trait, and since predators hunt by sight, they will be able to quickly recognize the fishes. A crucial part of repopulating the decimated population of preyed animals is played by larger female fish that have better broods.
As it is said that populations of fish that eat algae are threatened by predation, populations of large broods will only increase if predators are able to release large fish. This demonstrates that these would be less likely to be found among the population of algae eaters.

using tay-sachs disease as an example (as in your textbook), explain how a heterozygous individual can appear normal at the organismal level, exhibit an intermediate phenotype at the biochemical level, and exhibit both phenotypes at the molecular level
Tay-Sachs disease is a rare inherited disorder that results from a deficiency in an enzyme called hexosaminidase A (Hex A). This enzyme is responsible for breaking down a type of fat called GM2 ganglioside
which builds up in cells of the nervous system leading to their damage and death.
At the organismal level, heterozygous individuals (carriers) are considered normal as they have one functional copy of the gene encoding for Hex A and are able to produce enough of the enzyme to prevent the accumulation of GM2 ganglioside.
At the biochemical level, carriers may exhibit an intermediate phenotype as they produce reduced levels of Hex A compared to normal individuals. This can result in a moderate accumulation of GM2 ganglioside, but not enough to cause significant damage to the nervous system.
At the molecular level, carriers have both normal and mutant alleles ofthe Hex A gene. Analysis of the molecular phenotype would reveal the presence of both normal and mutant forms of the enzyme, explaining the intermediate phenotype seen at the biochemical level.
It is important to note that carriers do not show any symptoms of

Extracellular calcium (Ca2+) influx through voltage-dependent L-type Ca2+ channels initiates the calcium transient in response to sarcolemmal depolarization; this calcium influx causes the release of stored Ca2+ from the sarcoplasmic reticulum (SR) via Ca2+ release channels (ryanodine receptor 2, RyR2).
The ryanodine receptors (RyRs) in the SR cardiac activate and release calcium, stimulating contraction, when the action potential invades T-tubules and opens the L-type calcium channels. The sarcoplasmic reticulum supplies the majority of the calcium required for contraction, and this calcium is released by a mechanism called calcium-induced calcium release.
