3. Compound to makes up all masses
4. Elements cannot be broken down into another substance
Answers
Answer:
Common examples include carbon, sulfur, oxygen, iron, copper, aluminium. Elements are represented by symbols. Compounds are substances made from atoms of different elements joined by chemical bonds. They can only be separated by a chemical reaction.
Explanation:
Substances can be categorised as either elements or compounds. Both of these are made up of atoms, the only difference is an element is made of one type of atom whereas compounds are made of two or more different types of atoms.
Answer:
4) Elements cannot be broken down into another substance
Explanation:
Compounds are made up of multiple elements (different or same element). Whereas, elements are made up of single type of atoms. Water is a compound which can be broken down into Hydrogen and oxygen using chemical reactions whereas, you cannot break elements down into another substance.

In horses, the allele for a bay coat (brown with black mane, tail, and legs) and the allele for a cream coat can combine to make a
buckskin coat. The allele c is used for bay: CC is used for cream. Buckskin horses have one bay and one cream allele. The
genotype cc makes a buckskin coat, as neither allele is dominant. Cross a bay stallion (father) with a buckskin mare (mother).
How many offspring will have the same phenotypes as the mother.
Please help me
Answers
Answer:
100%
Explanation:
By crossing a bay stallion with a buckskin mare, 100% of offspring will have the same phenotypes as the mother (i.e., buckskin mare).
An allele is a gene variant, diploid organisms (like horses) inherit two alleles for a given gene locus, one allele from the mother and another from the father.In complete dominance, the dominant allele completely masks the expression of the recessive allele in heterozygous individuals.In codominance, both alleles are expressed in order to produce a given phenotype.In conclusion, by crossing a bay stallion with a buckskin mare, 100% of offspring will have the same phenotypes as the mother (i.e., buckskin mare).

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.

Which type of growth can occur only when a population has unlimited resources?
limited
logistic
exponential
negative
Answers
Answer:
c. on edge
Explanation:
When resources are unlimited, populations exhibit exponential growth, resulting in a J-shaped curve. The correct answer is c) exponential.
What is the exponential growth curve?Exponential growth curves and logarithmic growth curves are the two different forms of growth curves. In an exponential growth curve, the slope increases steadily over time. A logarithmic growth curve has a steeply increasing slope that gradually flattens out over time.
The exponential growth curve, which has a J-shape, shows a period of time where the results develop rapidly and steadily. It is the reverse of gradual progress. This curve initially climbs gradually before accelerating, which represents multiplied growth.
With exponential growth, a population's growth rate per capita (per person) remains constant regardless of population size, causing the population to expand exponentially as it grows larger. In nature, populations may expand exponentially for a while, but ultimately, their growth will be constrained by the availability of resources.
Exponential expansion happens when resources are unrestricted. Due to the favorable conditions, there are a lot more births as a result of the food excess.
Therefore, the correct answer is c).

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
Answers
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.

Proteins make genes. True or False? Why?
Answers
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.

In a moth population, 47 are brown, 15 are yellow, and 34 are black. What is the approximate probability of a moth being black?
A. 2%
B. 49%
C. 16%
D. 35%
Answers
Answer:
D
Explanation:
34/96= 35%
The mathematical rule of three can be used to take probabilities. In the exposed example, the approximate probability of a moth being black is 35% (Option D).
------------------------
Available data:
47 moths are brown15 moths are yellow34 moths are blackThe total number of individuals in this population equals the addition of brown, yellow, and black individuals.
This total number of individuals equals 100% of the population.
So to get the probability of a moth being black, we can just perform a rule of three.
To do it, we need to get the percentage of black individuals in the current population.
96 moths ------------------------- 100% population
34 black moths ----------------- X= (34 x 100) / 96
=35.41 ≅ 35% of the population
The approximate probability of a moth being black is 35%.
