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.

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.

In the question, we are told that there are;

We 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.

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.

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.

Answer:

Artificial selection

Explanation:

Choice A, artificial selection, led to the presence of these traits in French bulldogs.

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.

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.
