Answer:
Chromosomes are the structures found in the nucleus of a cell. They are made from DNA, containing hereditary information in the form of genes that control how an organism will look and behave.
Chromosomes come in homologous pairs (one from each parent) that each contain thousands of genes, determining traits expressed in the offspring.
Explanation:
Chromosomes are the structures found in the nucleus of a cell. They are made from DNA, containing hereditary information in the form of genes that control how an organism will look and behave. - this is true. Prior to cell division, DNA molecules are organized into large structures called chromosomes. Specific regions of a DNA molecule are called genes. These dictate specific proteins which control our traits.
Genes contain thousands of chromosomes that carry specific information about building proteins for a particular trait. - this is false - genes are segments of DNA that control specific traits by dictating the structure and functions of proteins. Chromosomes contain thousands of genes
Chromosomes are small sections of DNA that contain specific information about a trait to build proteins that people inherit. The thousands of different chromosomes passed from the parents allow for humans to look uniquely different. - this is false - chromosomes are large structures, genes are the relatively small sections of DNA. Humans have 23 pairs of chromosomes, not thousands.
Chromosomes come in homologous pairs (one from each parent) that each contain thousands of genes, determining traits expressed in the offspring. - this is true. In diploid organisms, like humans, have two copies of each chromosome. These chromosomes contain slightly different versions of genes, which make us unique.

Explain the process of DNA Replication in details
When will DNA replication occur?
(They don’t have to be too long just long kinda lol)
Answer:
DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. ... Once the DNA in a cell is replicated, the cell can divide into two cells, each of which has an identical copy of the original DNA.
In the eukaryotic cell cycle, chromosome duplication occurs during "S phase" (the phase of DNA synthesis) and chromosome segregation occurs during "M phase" (the mitosis phase).
Explanation:
The daughter cells that are produced in meiosis are genetically identical? 
True or false
Answer:
True
Explanation:
I hope this helps
Answer: True
Explanation: Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. In contrast, meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell.

atoms?
molecules?
cells?
Answer:
presence of cells
Explanation:
All living things are composed of cells. A cell can be defined as a complex biological arrangement that has all the structures and materials required for life. Cells carry out specialized functions such as, for example, metabolic functions to convert nutrients from food into energy (ATP), and reproduce by mitosis and/or meiosis. Thus, the cell is known to be the basic unit of life.

Over years of selective breeding, French bulldogs have developed extremely short snouts and flat faces. These traits, although attractive to the dog owners, can make it difficult for the dogs to breathe.Which of the following processes led to the presence of these traits?
(Choice A)
A
Artificial selection
(Choice B)
B
Natural selection
(Choice C)
C
Environmental selection
(Choice D)
D
Sexual selection
Answer:
Artificial selection
Explanation:
Choice A, artificial selection, led to the presence of these traits in French bulldogs.
What is Artificial selection?Artificial selection, also known as selective breeding, is the process of breeding organisms with desirable traits in order to produce offspring with those traits. In the case of French bulldogs, humans selectively bred dogs with shorter snouts and flatter faces in order to create a breed that was aesthetically pleasing. However, these traits also led to health problems such as difficulty breathing.
Natural selection, on the other hand, is the process by which organisms with advantageous traits are more likely to survive and reproduce, leading to the evolution of those traits in a population.
Environmental selection refers to the process by which the environment favors certain traits over others. Sexual selection is a type of natural selection that occurs when individuals with certain traits are more likely to attract mates and reproduce.
In the case of French bulldogs, these traits were not naturally selected for based on survival advantages, nor were they the result of environmental or sexual selection. Rather, they were artificially selected for by humans, leading to unintended consequences for the dogs' health.

Both mixtures and compounds are made of two or more different substances mixed together. So
which of the following is an accurate statement about the difference between the two?
a- generally speaking compounds are easier to separate than mixtures
b- compounds are mixed physically but not chemically
c- a mixture is two or more substances mixed physically but not chemically
d- mixtures are pure substances while compounds are not
Answer:
c- a mixture is two or more substances mixed physically but not chemically
Explanation:
In chemistry, a mixture and a compound is made up of two or more different substances that combines together, however, the difference between the two is in the way the combination occurs. Compounds are pure substances formed as a result of the chemical combination of two or more elements. The atoms of the elements in a compound are chemically bonded together in such a way that they cannot be separated.
On the other hand, mixtures are substances composed of two or more substances of different properties that are combined physically i.e. there is no chemical bonding between them, hence, components of a mixture can easily be separated using physical methods like boiling, melting, etc dependent on the individual properties of the components.
Give an example of a natural resource
Answer:
Any natural substance that humans use can be considered a natural resource. Oil, coal, natural gas, metals, stone and sand are natural resources. Other natural resources are air, sunlight, soil and water. Animals, birds, fish and plants are natural resources as well.

The chemistry café cook has a loaf which had 33 slices and a package of cheese that has 15 slices. he is making sandwiches that have 2 pieces of both breed and cheese. how many sandwiches can he make?
Answer:
Explanation:
so
2 breads + 2 cheeses ⇒ 1 sandwich
if we use two slices of bread each time how many sandwich can we make with 33 slices
33/2 =16.5 sandwiches
if we use two pieces of cheese in each sandwiches how many sandwiches can we make with 15 slices ?
15/2 =7.5 sandwiches
the cheese her will run out first and we would have excess bread
so we would only be able to make 7.5 sandwiches without running out of ant ingredient :)
From the calculations, we can see that the producer can make about 12 sandwiches.
Bread and cheeseIn the question, we are told that there are;
a loaf which had 33 slicesa package of cheese that has 15 slicesWe also know from the question that he is making sandwiches that have 2 pieces of both breed and cheese.
Hence; total number of bread and chese = 33 + 15. Each bread must contain two pieces of each of the bread and chees making a total of four pieces. He can therefore make; 33 + 15/4 = 12 sandwiches.

Explain in your own words the "lemur experiment."
this is from the pbs-nova-the great math mystery worksheet pls help
Answer:
The answer is below
Explanation:
Lemur Experiments in Mathematics shows that there are animals who also possess the human sense of understanding numbers.
The Lemur experiment proved that lemur can distinguish numbers even when there is no language or graphical representation. This is synonymous in comparison with humans' ability to relate amounts without the typical counting.
Hence, it was concluded that the ability to comprehend numbers can serve as a means of observing the scientific relationship between humans, mathematics, science, and engineering.
The mass of the earth is 81 times the mass of the moon. Using Newton's Law of Gravity what would the affect of gravitation be if the mass of the moon were doubled and the distance was also doubled?
Group of answer choices
4 times the gravitational attraction
twice the gravitational attraction
1/4 the gravitational attraction
Half the gravitational attraction
Answer:
it would be half the the gravitational attraction(D) because the distance Has doubled.
If the mass of the moon were doubled and the distance between them is also doubled, then it will have half the gravitational attraction. The correct option is D.
What is gravitational force?The gravitational force is basically a force that attracts any two mass-bearing objects. The gravitational force is called attractive because it always tries to pull masses together rather than pushing them apart.
According to Newton's law of gravitation, the force of gravitation is inversely proportional to the square of the distance between the bodies. Thus, doubling the distance reduces the force of gravitation by 1/4.
If one of the objects' mass is doubled, the force of gravity between them is also doubled. If one of the objects' mass is tripled, so is the force of gravity between them. If the mass of both objects is doubled, the gravitational force between them is quadrupled, and so on.
Now, here, the mass is being doubled which is making the gravitational attraction doubled. But distance is also increasing by two.
So in this case, the gravitational attraction will get 1/4, so the net attraction will be half.
