Which pair of nitrogenous bases will form a bond in a DNA molecule?
Answer:
Adenine and Thymine
Explanation:
Answer:
Adenine Thymine
Explanation:
Adenine, thymine, cytosine and guanine are ___________________ instructions to cells.
DNA is essentially a storage molecule. It contains all of the instructions a cell needs to sustain itself. These instructions are found within genes, which are sections of DNA made up of specific sequences of nucleotides. In order to be implemented, the instructions contained within genes must be expressed, or copied into a form that can be used by cells to produce the proteins needed to support life.
The instructions stored within DNA are read and processed by a cell in two steps: transcription and translation. Each of these steps is a separate biochemical process involving multiple molecules. During transcription, a portion of the cell's DNA serves as a template for creation of an RNA molecule. (RNA, or ribonucleic acid, is chemically similar to DNA, except for three main differences described later on in this concept page.) In some cases, the newly created RNA molecule is itself a finished product, and it serves an important function within the cell. In other cases, the RNA molecule carries messages from the DNA to other parts of the cell for processing. Most often, this information is used to manufacture proteins. The specific type of RNA that carries the information stored in DNA to other areas of the cell is called messenger RNA, or mRNA.
How does transcription proceed?
Transcription begins when an enzyme called RNA polymerase attaches to the DNA template strand and begins assembling a new chain of nucleotides to produce a complementary RNA strand. There are multiple types of types of RNA. In eukaryotes, there are multiple types of RNA polymerase which make the various types of RNA. In prokaryotes, a single RNA polymerase makes all types of RNA. Generally speaking, polymerases are large enzymes that work together with a number of other specialized cell proteins. These cell proteins, called transcription factors, help determine which DNA sequences should be transcribed and precisely when the transcription process should occur.
A couple just brought home their new baby from the hospital. They begin to suspect that the hospital switched babies, and the baby they brought home is not theirs. They check the hospital records, and findthat the man’s blood type is B, the woman’s blood type is AB, and the baby’s blood type is O. Explainwhy the parents are or are not justified in theirconcern about this babyRequired to answer. Single line text.
Answer:
Explanation:
the baby is not theirs because the father has a blood type of OB so he can give an O or a B and the mother has a blood type AB so she can give either an A or a B so their child could either be of blood type A or B or AB but not O

Please i need a correct and accurate answer. ++ giving brainliest
Answer:
Explanation:
The immune system is there to develop a strong answer for infections and diseases that can occur in the body. The system is comprised also of gastrointestinal immune cells. These cells secrete lymphocytes that are there to attack whatever is attacking our body. The gut immune cells and the microflora located inside it are responsible for preventing the growth of other microbes that are bad for us in the gut and to fight ingested pathogens that we can get on our food.

What is the role of sensory organs in the body?
Sensory organs are organs of the body that access those sensory capabilities and help us become conscious and respond to our surroundings. There are two types of receptors depending on the sensory organ: general receptors and special receptors. General receptors are present in the skin and muscles.
Hope this helped :)
Sense organs play a major part in a diversity of functions and assist in feeling our surroundings.
These are an essential portion of our cores that allow us to smell the terrain around us. Sensation organs and their receptors detect multitudinous stimulants that are also communicated to the intellect.
A network of jitters and sense organs is companies with clarifying data in reaction to a special bodily miracle. This is the route that decides our commerce and replies to the terrain.
We've five direct sensitive organs and the sense organs titles are cognizance, Eyes, Ears, Nose, Tongue, and Skin. These definitive five sensitive organs support sensing sound, glare, aroma, flavor, and hold, independently.

Why is taxonomy important? Taxonomy allows scientists to analyze DNA and RNA sequences. Taxonomy allows a better understanding of relationships among species. Taxonomy allows the manipulation of genes for medical purposes. Taxonomy allows scientists to use both common names and domains of life.
Answer:
Taxonomy allows a better understanding of relationships among species.
Explanation:
Taxonomy is important because it allows a better understanding of relationships among species. Thus, the correct option is B.
What is Taxonomy?Taxonomy may be defined as the process of classification of living organisms on the basis of their characteristics.
Carolus Linnaeus, a Swedish botanical taxonomist is known as the father of taxonomy. He was the one who formulate a classical system for defining living plants and animals on the basis of their defining characteristics.
Therefore, taxonomy is important because it allows a better understanding of relationships among species. Thus, the correct option is B.

How does interphase prepare cells for mitosis?
Answer:
Growth of cell and replication of DNA
Explanation:
[tex] \large{ \underline{ \bf{Interphase}}}[/tex]
It is a long, non-dividing, growing phase of the cell cycle, where the cell prepares itself for division.It represents the most active stage of the cell cycle where both cell growth and DNA replication occur in an orderly manner.It is the period of intense growth and synthesis in which a cell stocks all the biomolecules required during cell division.It is called the resting phase because there is no apparent activity related to cell division rather, it deals with the changes that occur in a cell and the nucleus, before it enters into cell division.Please help!

The theory of how the first cell came to be are based on two assumptions. What are those two assumptions?
Answer:
1. All living things are made up of cells.
2. Cells are the basic building blocks of life.
3. All cells come from preexisting cells created through the process of cell division.
As science evolved, three more components were added to the theory. Some biology classes don’t require you to know these parts of the cell theory because they weren’t part of the original definition, but it’s still useful to be aware of them:
4. Energy flow occurs within cells.
5. Hereditary information is passed from cell to cell.
6. All cells have the same basic chemical composition.
So what does the cell theory actually mean? Let’s break it down. The first part of the cell theory states that all living things are made up of cells. Anything that’s alive, from bacteria to plants to humans, is composed of cells. And what are cells? The literal definition is a cell is a group of organelles surrounded by a thin membrane.
The cell theory definition states that cells are the building blocks of life. Cells both make up all living things and run the processes needed for life. Your hair, skin, organs, etc. are all made up of cells. In fact, each person is estimated to be made up of nearly 40 trillion cells! Each part of a cell has a different function, and your cells are responsible for taking in nutrients, turning nutrients into energy, removing waste, and more. Basically, everything your body does, it does because cells are directing the action!
The third part of the cell theory definition states that all cells come from preexisting cells. This means that cells don’t just appear out of thin air (known as “spontaneous generation”). New cells are always made from current cells. This means that all current life on the planet is descended from the very first cells, which first made an appearance on Earth roughly 3.5 billion years ago. Cells have been replicating themselves continuously ever since.
And what does the newer part of the cell theory state? Part four refers to the fact that, in all living cells, energy is continuously transformed from one type to another. Examples of these processes include photosynthesis (where plant cells convert light energy into chemical energy) and cellular respiration (where both plant and animal cells convert glucose into energy). Part five refers to DNA and the fact it is passed from parent cell to child cell. Finally, part six of the cell theory tells us that all cells are made up of the same chemicals: water, inorganic ions, and organic molecules.
Explanation:
Label the effect depicted in the picture below. How does
the picture connect to the definition?
(Amoeba sisters, video recap, genetic drift. Question number 2.)
Answer:
Bottle-necking effect.
Explanation:
Like in the picture below the bottlenecking effect works the same way in nature. When we shake the bottle some kinds of candies may fall out and some may not. This doesn't represent the whole bottle. Some type may not even fall out because the bottle wasn't wide enough for it to fall out. This can happen in nature too. In a forest fire where some animals survive they didn't survive because they were adapted to fire. They just weren't in the part of the forest that was on fire. So with the new allele frequency in the new population, this is a bottleneck effect.
