A graduated cylinder containing 40 mL of water has a total mass of 60 g. A solid object carefully lowered into the graduated cylinder. The level of the water rises to 70 mL. The total mass of the cylinder, water and object is now 95 g what is the mass? volume? and density

Answers

Answer 1

Answer:

The correct answer is -

A) 35 g

B)30 mL

C)1.66666666666667g/ml3

Explanation:

Given:

mass of graduated cylinder containing 40 mL = 60 g

volume of water = 40 ml

increase in the level of water = 70 ml

increase in mass = 95

Solution:

A) mass of object -

increased mass - initial mass

90 - 60 = 35 g

B) volume of object

increased volume - initial volume

70 - 40 = 30 mL

C)  density d=m/v

d=35/30

d=1.66666666666667

Answers

Answer:

Asexual reproduction.

Explanation:

The generation of genetically identical offspring from a single parent, without the fusion of sperm and egg, is called asexual reproduction. Asexual reproduction occurs when there is only one parent from which organism is produced. Budding, binary fission and fragmentation are the different types of asexual reproduction that involves only one parent and no fusion of sperm and egg cells.

The models below represent nuclear reactions. The atoms on the left of the equal sign are present before the reaction, and the atoms on the right of the equal sign are produced after the reaction. Model 1: Atom 1 + Atom 2 = Atom 3 + energy Model 2: Atom 4 = Atom 5 + Atom 6 + energy Which of these statements is most likely correct about the two models? Both models show reactions which produce energy in the sun. Both models show reactions which use up energy in the sun. Model 1 shows reactions in the nuclear power plants and Model 2 shows reactions in the sun. Model 1 shows reactions in the sun and Model 2 shows reactions in a nuclear power plant.

Answers

Answer:There are two kind of nuclear ractions: fusion and fission reactions.

Both release a huge amount of energy in different ways.

Fusion reactions are nuclear reations in which two smaller (lighter) atoms combine into a larger (heavier) atom, with the respective release of energy.

That is what model 1 shows:

Model 1: Atom 1 + Atom 2 = Atom 3 + energy

That is the process that happens and is responsible for the huge amount of heat produced in and released by the Sun.

In the Sun two atoms of hydrogen fuse into a larger atom of helium.

That is represented by the nuclear reaction:

Any organism that lacks internal membranes, which prevents the formation of a distinct nucleus and other organelles, is referred to as a prokaryote (also written procaryote). The most well-known prokaryotic species are bacteria. Prokaryotes are different from eukaryotes because they don't have internal walls.

Separate prokaryotic kingdoms with purportedly distinct evolutionary histories are called bacteria or eubacteria and archaebacteria or archaea.

An ecological footprint A) is a means of determining increases in populations that lived in the past. B) is a means of understanding resource availability and usage. C) measures dispersion and adaptability. D) will estimate population movements.

Answers

Answer: An ecological footprint is a means of understanding resource availability and usage. The correct option is B.

Explanation:

The ecological footprint is a method which is used to measure the rate as which humans use natural resources in their environment and generate waste from them compared with how fast nature can absorb these wastes and generate the used resources again. The productive areas which are measured through this means are:

--> cropland,

--> grazing land,

--> fishing grounds,

--> built-up land,

--> forest area, and carbon demand on land.

The importance of ecological footprint to the environment should no the over emphasizes. When properly observed, different environmental pollution would be dealt with. Generally, there would be:

--> decreased desertification,

--> decreased global warming

--> availability of fresh unpolluted air and

--> decreased carbon emissions.

Area = length * width

A = 4m * 3m

A = 12 m^2

(Area is measured in square units)

Answer:

D. 12 m2

Explanation:

To do this problem, you need to find the area. To find the area of a rectangle, you multiply length x width. In this scenario:

4 x 3 = 12.

So, we know that the first two options are incorrect. Next, we have to look at the unit of measurement that we are needed to imply. In this case, we are using meters, which we need to square. Therefore, the answer is 12 m2.

Do different patterns of electrical signals have unique

Answers

Answer:

Plants use electric fields to communicate with bees, scientists have learned.

Bumblebees are able to find and decipher weak electric signals emitted by flowers, according to the study.

Tests revealed that bees can distinguish between different floral fields, as if they were petal colours. The electric signals may also let the insects know if another bee has recently visited a flower.

Explanation:

How bees detect the fields is unknown, but the researchers suspect the electrostatic force might make their hair bristle. A similar hair-raising effect is seen when placing one's head close to an old-style TV screen.

Flowers were already known to use bright colours, patterns and enticing scents to attract pollinators.
