Answer:

The DNA of an amphibian, such as a frog, is different from the DNA in a human because a frog's DNA contains a different number and sequence of nitrogenous bases (option A).

Explanation:

DNA is the molecule that contains all the genetic information of the different species of living beings, being a molecule that is present in all of them.

Although the DNA of all living beings has the same basic structure —four nitrogenous bases, a deoxyribose and a phosphate group— what makes the differences between species is the length of the DNA molecule and the different sequences of nitrogenous bases present in the molecule. It is for this reason that frog DNA is different from human DNA.

The other options are not correct because:

B. There are no differences in the phosphate groups from one species to another.

C. All DNA molecules contain guanine and adenine.

D. Hydrogen bonds between nitrogenous bases depend on the amount of paired bases, but are not related to differences in DNA between species.

grandymaker [24]

Answer:

The correct answer is c) are plant cells.

Explanation:

The cells cannot be animal cells, because they have not wall (this kind of cells has only plasma membrane). In addition, eukaryotic cells have membrane-bound organelles (which are surrounded by a phospholipids membrane, such as endoplasmatic reticulum, Golgi apparatus, lysosomes, etc.), whereas prokaryotic cells lack them. Since plant cells are eukaryotic and bacterial cells are prokaryotic, the cells you are looking are plant cells.

You select seeds from the largest, tastiest watermelons from your garden every year and use them to grow the next year's fruit.

Step2247 [10]

There would be less variability in the genes of the watermelon plants and is denoted as option A.

<h3>What is Variability?</h3>

This is defined as the difference between organisms which is caused by genetic or environmental factors.

Using the seeds from the largest, tastiest watermelons will reduce variability over time because these characteristics will become dominant.

A scientist wants to know if adults prefer watching movies in a theater or in their home. He interviews 500 people leaving a loc

JulijaS [17]

Answer:

The scientist's conclusion is most likely unreliable because he just interviewed people watching movies in the theatre. He should have interviewed an equal number of people from the theatre and from home to get reliable results. According to the scientific method for designing an experiment, the experiment or survey conducted by scientists is not correct. Hence, the scientist's conclusion is wrong because his method of experimentation was wrong.

How to explainn volume to a 10 year od

marusya05 [52]

Show them a glass of water.
tell them that the water is obviously in 3d because its not flat. Because this water takes up space in this glass it has a volume 

Say anything that's 3d has a volume, even a 3d movie possibly. I know SPY KIDS 3 came out and some of the characters or things would jump off the screen. Since they aren't flat like a normal tv they have a volume
