TRUE OR FALSE: A coiled structure of DNA and protein that forms in the cell nucleus during cell division is called a chromosome
Answer:
TRUE!!!
Explanation:
In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
hope this helps! :D
A chromosome is a coiled DNA and protein structure that develops in the cell nucleus during cell division.
Thus, chromosomes are important for transporting and passing genetic information from one generation to the next. They house an organism's genetic material. When cells divide, they become visible under a microscope and take the form of compressed formations. Every species has a certain number of chromosomes.
Chromosomes are essential for cell division because they make sure that genetic material is accurately distributed to daughter cells. For effective cell function and heredity, they must have a compact and well-organized structure made of DNA securely coiled around histone proteins.

explain in your own words : Are mutations good or bad for a population
Answer:
Mutational effects can be beneficial, harmful, or neutral, depending on their context or location. Most non-neutral mutations are deleterious. In general, the more base pairs that are affected by a mutation, the larger the effect of the mutation, and the larger the mutation's probability of being deleterious.The California current is an ocean current that moves cold water from the north along the west coast of the United States.

Which structures can be found on a protist but not on a fungus?
Answer:
See the answer below
Explanation:
First, there is a need to know that protists are unicellular, animal-like living organisms while fungi are unicellular/multicellular, achlorophyllous, and heterotrophic decomposing organisms.
A typical protist may have a plant-like cell wall or just an animal-like cell membrane without a cell wall. This is unlike fungi whose structure includes a rigid, chitin-containing cell wall.
Most protists also have locomotive structures that enable them to be motile. For example, the amoeba has pseudopodia, the paramecium has cilia, while the euglena has flagella. Fungi generally are immotile, that is, they do not have any locomotive structure that enables them to move.
Some protists have two vacuoles - contractile and food vacuoles - which assist them in essential functions such as osmoregulation and nutrition. Unicellular fungi such as yeasts only have a single vacuole.
Some protists such as the euglena have chloroplast which enables them to photosynthesize in addition to other forms of nutrition. Fungi generally, however, are achlorophyllous. They lack chloroplast/chlorophyll in any form.

main stages of the cell cycle
Answer: The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage). The stages G1, S, and G2 make up interphase, which accounts for the span between cell divisions.

Which definition best describes an acid?
Answer:
A substance in a solution that releases and captures hydrogen ions, keeping the pH the same
Explanation:
A substance that may release a proton or hydrogen ion (H +) is referred to as an acid.
What is acid?Hydrogen ions and chloride ions are created when hydrogen chloride, which is suspended in water, ionizes. A particle or ion that may produce a hydron (proton or hydrogen ion H+ is known as an acid.
Any hydrogen-containing material that has the ability to donate a proton (hydrogen ion) to another chemical is considered an acid. A base is a molecule or ion that can take up an acid's hydrogen ion.
Typically, sour tastes help to identify acidic chemicals. capable of forming a covalent connection with an electron pair on (a Lewis acid). Proton donors, also known as Brnsted acids, make up the first level of acids.
Therefore, that may release a proton or hydrogen ion (H +) is referred to as an acid.

Which of the following statements is correct?
Your eyes look different than your liver, because the cells that make up these
organs have different genes.
o As cells and tissues differentiate, they lose the genes they do not need.
O All cells have the same genes, but different genes are active in different cells.
Cells do not have DNA.
Answer:
The statement that is correct is that all cells have the same genes, but different genes are active in different cells.
Explanation:
Differentiation or specialization is a function that cells possess and is what allows them to have different types of cells and tissues.
Cell differentiation depends on genetic regulation, a mechanism that determines the specific genes that are expressed in a cell or tissue type.
All cells contain the same DNA, which is organized into chromosomes and contain the genes that determine specific characteristics. There is cell differentiation because some genes can be expressed and others are suppressed, all due to genetic regulation.
The other choices are wrong because:
The eyes look different from the liver, because they have the same genes, but only some are expressed. Differentiated cells and tissues do not lose their genes. All cells have DNA.An organism is struggling to get enough food for it to survive. How would this affect the cell cycle and cell division?
