Then, what is the question????

In 1665, Robert Hooke, a scientist published Micrographia, a book full of illustrations and descriptions of organisms observed under the recently invented microscope, hence Hooke's discovery of the cell was successful with the invention of the microscope.

A microscope is defined as a laboratory instrument used to examine objects that are too small to be seen by the uncovered eye. Microscopy is the science of examining small objects and structures using a microscope. The word microscopic means invisible to the eye unless aided by a microscope.

Without the microscope, we would not know about the existence of cells or how plants breathe or how rocks change over time. Cell theory was discovered by Robert Hooke in 1665 with the help of a microscope.

Thus, in 1665, Robert Hooke, a scientist published Micrographia, a book full of illustrations and descriptions of organisms observed under the recently invented microscope, hence Hooke's discovery of the cell was successful with the invention of the microscope.

Answer:

Deletion mutation

Explanation:

A deletion mutation can remove a single nucleotide, or entire sequences of nucleotides

A cell can be described as the structural and functional unit of life. It can also be described as the building material of all living organisms.

Without the cell, most living organisms will not be able to function. An organelle will not be able to survive that long within its life span without the presence of cells. It will just withe and die off.

Lots of scientists have proved in various ways the existence of cells, this is because they have been able to create microscopes that can see these tiny cells. This is evidence that proves the existence of cells.

Answer:

True

Explanation:

Sea anemones are one of the numerous predating animals found in the marine environment. They have cylindrical bodies whose bases are usually found attached to substrates and are therefore described as being sessile. However, a few species of sea anemones are known to be free swimmers.

Generally, sessile organisms are those that live their life attached to a substrate and, therefore, are not able to freely move about.

Answer:

True

Explanation:

This is because sea anemone polyp is permanently attached to the beneath of the base where it stay by it base called pedal foot. It sometimes glide around in order to prevent itself from predation and it uses it's tentacle to catch moving food particles around it and consume it. It belong to the group cnidaria.

Answer:

The early Earth was very different from our Earth today.

Explanation:

Earth's first atmosphere had lots of water vapor but had almost no oxygen. Later, frequent volcanic eruptions put several different gases into the air (Figure 12.13). These gases created a new type of atmosphere for Earth.

Answer:

The atmosphere we enjoy today is radically different from the atmosphere that formed with the Earth billions of years ago. ... As the Earth cooled enough to form a solid crust (4.4 billion years ago), it was covered with active volcanos. These volcanos spewed out gasses, like water vapor, carbon dioxide and ammonia.

How has the Earth's atmosphere changed over time?

Water vapor, carbon dioxide, methane, ammonia, and other gases similar to the ones produced by volcanoes today were expelled. Over a vast amount of time, millions of years, the earth gradually cooled. ... From these clouds, the oceans formed and the oceans absorbed a lot of the carbon dioxide in the atmosphere.

Explanation:

This is because the black hybrid would be 50% one breed and 50% another breed. Then the white purebred is 100% one specific breed. So by mating, all of those breeds that the parents have all reduce by 1/2 for the offspring.

Answer:

It depends on the salt concentration inside the cell.

Explanation:

The movement of water through a semi-permeable membrane with different salt concentrations depends on the amount of water and salt concentration in the cell. If the cell has more salt concentration so no more salt moves inside the cell but moves outside the cell while on the other hand, if the cell has low amount of salt than the outer environment then the salt moves inside the cell until its concentration are equal.

Answer:

Crossing two chickens heterozygous for the trait feather color, when brown feathers are dominant over red feathers, will produce offspring with brown and red feathers in a brown:red phenotypic ratio of 3:1.

Explanation:

Knowing that in chickens brown feathers are the expression of the dominant allele (B) and the recessive allele is red (b), crossing two heterozygous individuals (Bb) will result in offspring that are likely to have brown or red feathers.

The cross can be represented by a Punnett Square:

Bb X Bb cross

alleles     B    b

B             BB Bb  

b             Bb bb

Where the result is:

Genotypes:  

Phenotypes:

In this case, the probability of having brown or red feathers is 3:1.

Answer:

weathering

erosion

Explanation:

Weathering can be explained as the

breaking down of rocks as well as minerals or dissolving it on the surface of the earth. After the rock has been broken down then the bits of the rock can be transported away in a process known as " Erosion". The agents of

weathering and erosion could be water, salt, animal as well as plants.

It should be noted that the parts of sedimentary rocks formation that include the breakdown is weathering while the parts of sedimentary rocks formation that include carrying away of existing rock is erosion.

Answer:

The apple reflects red light and absorbs all other visible wavelengths

Explanation:

The apple is only reflecting the color red and is absorbing the other colors of light (wavelengths)

The correct explanation why an apple looks red is that the apple reflects red light and absorbs all the other visible wavelengths. Thus, the correct option is A.

Light absorption is the process in which the light ray is absorbed by the matter and converted into a form of energy. In an atom, the electrons vibrate at a specific frequency, then this is called as the natural frequency.

Reflection is a phenomenon of light. When a ray of light approaches a smooth polished surface such as metal and the light ray bounces back, it is called the reflection of light. The incident light ray which land on the surface is reflected off from the surface. The light ray that bounces back is called the reflected ray.

Therefore, the correct option is A.

Answer:

Those organisms survive and maintain its population who are chosen by natural selection.

Explanation:

This statement means that when the population experiences a new set of environmental conditions, two things are happened i. e. the population either adjusts through natural selection or becomes extinct. The fossil of dinosaur indicates that extinction occur due to changed in the environment. If the population made changes in itself and adapt the environment then the organism survive otherwise extinction occur.
