Help me past due Write down what you think will happen to the density of water if you add salt or sugar.

Biology
1 answer:
Gennadij [26K]2 years ago
6 0

Answer:

If I add sugar or salt, the water's density will increase.

Explanation:

Density is the relation between mass and volume. We can represent it with the formula δ= m/v. Where δ stans for density, m for mass,  v for volume.

If we add salt or sugar, we increase the mass, but the volume is the same. As a result, the density will increase.

We can use numbers to understand it better.

Suppose that before adding salt or sugar, the mass is 1 g and the volume is 1 l

δ= 1g/l1t

δ= 1 g/lt

Now, if we add sugar or salt, the mass increases. Suppose that we have 2g of mass and the volume is the same, 1l.

δ= 2g/1lt

δ= 2g/lt

We can see that the density increased when the mass increased.

Which statement describes Redi's experiment, which helped disprove spontaneous generation?
Lelu [443]

Answer:

He examined covered and uncovered meat to determine that maggots came from eggs.

Explanation:

Prior to Redi's experiment and other supporting experiments, it was formerly believed that life could emanate from non-living things, for example, the generation of maggots from rotting meat.

In 1668, a scientist called Francesco Redi disproved the idea of spontaneous generation. He did this when he experimented that the maggots from meats are only as a result of eggs laid by flies when they perched on the meat.

He placed the meat in two jars; an uncovered jar and another in a covered jar with a cloth, after several days, the uncovered jar had maggots on the meat, while the covered jar had no maggot on the meat, but on the cloth. With this experiment, he was able to demonstrate that the maggot arose from the eggs of the flies, not the meat itself which is nonliving and hence, disproved the idea of spontaneous generation.

Jason has five equally massed lead fishing weights, each weighing 250 grams. What is the total mass of the five lead fishing wei
algol [13]

Answer:

1250 g=1.25 Kg

Explanation:

We are given that Jason has five fishes of equally massed lead fish weights.

Weigh of each fish =250 grams

We have to find the value of total mass of the five lead fishing weights

Total number of fishes=5

In order to find the total mass we will use unitary method

Total mass is obtained by multiplying the total number of fishes with weight of one fish

Total mass=5\times 250

Total mass of five fishes=1250 g

1 kg =1000g

Then 1250 g=\frac{1250}{1000}=1.25 Kg

Hence, total mass of five lead fishing weights=1250 g=1.25 Kg
