Every organism requires a set of instructions that specifies its traits. This information is carried with the cells of the organism. Which set of statements BEST describes hereditary information in eukaryotic cells? Group of answer choices
Answer:
This question lacks options, the options are;
A. Genes are made up of chromosomes and both are found in the cell’s cytoplasm.
B. Chromosomes are made up of genes and both are found in the cell’s cytoplasm.
C. Genes are made up of chromosomes and both are found in the cell’s nucleus.
D. Chromosomes are made up of genes and both are found in the cell’s nucleus.
The correct answer is D.
Explanation:
As rightly stated in this question, every living organism requires a set of instructions that specifies its traits. These set of instructions are embedded in a unit called GENE. Genes hold information needed for the survival of a cell in an organism.
These genes are located on a structure called DNA, which are folded or packaged into another structure called CHROMOSOMES. Each chromosome, hence, contains genes that are the unit of inheritance of a cell. In eukaryotic organisms, the gene is found on a chromosome, which is located in the NUCLEUS of the cell.

Answer:
Desert ecosystems are located in regions that receive an annual rainfall less than 25. They occupy about 17 percent of all the land on our planet. Due to the extremely high temperature, low water availability and intense sunlight, fauna and flora are scarce and poorly developed. The vegetation is mainly shrubs, bushes, few grasses and rare trees. The stems and leaves of the plants are modified in order to conserve water as much as possible. The best known desert ones are the succulents such as the spiny leaved cacti. The animal organisms include insects, birds, camels, reptiles all of which are adapted to the desert (xeric) conditions.

The Forest Ecosystems
They are the ecosystems in which an abundance of flora, or plants, is seen so they have a big number of organisms which live in relatively small space. Therefore, in forest ecosystems the density of living organisms is quite high. A small change in this ecosystem could affect the whole balance, effectively bringing down the whole ecosystem. You could see a fantastic diversity in the fauna of the ecosystems, too.

Proteins make genes. True or False? Why?
Answer:
False
Explanation:
Because Genes make protein
But the genes in your DNA don't make protein directly. Instead, special proteins called enzymes read and copy (or "transcribe") the DNA code. The segment of DNA to be transcribed gets "unzipped" by an enzyme, which uses the DNA as a template to build a single-stranded molecule of RNA. Like DNA, RNA is a long strand of nucleotides.
This transcribed RNA is called messenger RNA, or mRNA for short, because it leaves the nucleus and travels out into the cytoplasm of the cell. There, protein factories called ribosomes translate the mRNA code and use it to make the protein specified in the DNA recipe.
If all this sounds confusing, just remember: DNA is used to make RNA, then RNA is used to make proteins-and proteins run the show.
The Cell's Secret Code
Some genes act as instructions to make molecules called proteins.
Answer:
False.
Explanation:
Since genes make protein
But proteins are not directly formed by the genes in your DNA. Instead, the DNA code is read and copied (or transcribed) by special proteins called enzymes. An enzyme that uses DNA as a template in order to build a single-stranded RNA molecule "disconnects" the DNA segment being transcribed. RNA is an extensive nucleotide beam, like DNA.
The messenger RNA, or mRNA, is for short transcribed, as it leaves the nucleus and moves into the cell's cytoplasm. The mRNA code is translated in protein plants named ribosomes and used to produce the protein specified in the DNA recipe.
If everything sounds confusing, just remember: RNA is made using DNA, and the proteins are being used as a show by RNA.
The Secret Code of Cell
Certain genes are used to make protein molecules.
a sodium atom that has lost an electron comes near a chlorine atom that has gained an electron
Answer:
When a sodium atom that has lost an electron comes near a chlorine atom that has gained an electron, an ionic bond is formed.
Explanation:
The bonds which are produced between a metal ion and a non-metal ion are termed as ionic bonds. Sodium is metal while chlorine is a non-metallic element, ionic bonds are formed in between them.
Sodium has one electron in its outer most shell whereas a chlorine atom has seven electrons in its outermost shell. To become stable, sodium donates its electron to the chlorine atom and hence ionic bond is formed between them.

Question 2 is option 2. It is the only one that makes sense and it says sediment sin it.
Explanation:
ecosystem contain both blank and blank parts
Explanation:
Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts.
Every ecosystem contains both biotic and abiotic components, such as the biotic component, which contains the living forms such as the animal and the plant, and the non-living components, which are called the abiotic component.
What role does the ecosystem play on Earth?There are numerous ecosystems on Earth, each with its own set of functions and living forms, but these are essential for human survival as they support a wide variety of plant and animal species, thus maintaining the biodiversity of the earth. By absorbing and storing carbon, forests, oceans, and wetlands help to regulate the earth's climate by managing the carbon cycle and regulating the climate.
Hence, every ecosystem contains both biotic and abiotic components, such as the biotic component, which contains the living forms such as the animal and the plant, and the non-living components, which are called the abiotic component.

1. Which weather station model above would most likely have snow? ___________
2. Which weather station model above would most likely have rain? ____________
3. Which weather station above has the highest air pressure? ____________
4. Which weather station model above has the highest wind speed?_________
Answer:
1. Station B
Station B has one of the lowest temperatures of 32°F(top left) which is a temperature that snow can form at. It also has full cloud cover which is something that station C does not have and as clouds are needed for snow, station B is most likely to have snow.
2. Station A
Station A has the highest dew point at 75 (bottom left) which means that it has the highest humidity and so is the most likely to have rain. That along with a full cloud cover (shaded circle), means there are clouds for rain to fall from.
3. Station B
Has the highest pressure at 998.
4. Station C
Wind speed is measured by the lines protruding from the circle and for this simplistic model, the more lines it has, the faster the wind is going. Station C therefore has the fastest wind speed.

Cutting down trees in a forest alters the habitat of the organisms living in the forest. The given statement is true.
What is habitat?
Habitat is known as the place where the animals lives and survive the place is known as the habitat. Cutting down the trees is known as the deforestation. The term migration has been defined as when the birds, animals, or human beings leaves the native place and move towards a new place due to weather or other physical condition is known as migration. Generally, when it is too much cold the birds of that particular area migrated to the place where they found suitable temperature for their survival.
The stage of dormancy is the stage when seed gets closed and not able to germinate as it closes its outer wall. The term hibernation is defined as the particular time period in which the organism hybernate himself for a period of time when the weather or the outer environment is not safe, or fit for his survival.Generally, when it is too much cold the birds of that particular area migrated to the place where they found suitable temperature for their survival.
