Answer:
Uracil
Explanation:
In RNA Adenine pairs with Uracil
In DNA Adenine pairs with Thymine
Thymine dos not exist in RNA
Hope this helps ^^
Adenine in DNA pairs with uracil in RNA. Therefore option “D” is correct.
What is nucleotide base pairing?There are five types of the nucleotide bases adenine, cytosine, guanine, thymidine, and uracil. These divide into two classes of nucleotides pyrimidine and purine nucleotide bases. Pyrimidines are uracil, thymine, and cytosine whereas adenine and guanine are purines.
DNA consists of adenine, cytosine, guanine, and thymidine. In RNA, adenine, cytosine, and guanine are present but thymine is replaced by uracil.
Pyrimidine always binds with the purines through hydrogen bonding. Adenine binds with thymine. Cytosine binds with guanine. But when adenine pairs with uracil in RNA.
Nucleotide base pairing is important for the stability of the DNA.

Nida draws a diagram with insects, birds, and mice. She shows the mice eating grass; hawks, snakes, and toads eating the insects; and foxes, hawks, and snakes eating the birds and mice. The snakes are also eating the toads.
Which best describes the diagram?
Answer:
This question lacks options, the options are as follows:
A. pyramid
B. food chain
C. food web
D. trophic level
Answer is C (food web)
Explanation:
Food web is simply referred to as the interconnection of numerous food chains in an ecosystem. A food web shows the numerous ways in which organisms eat one another in order to obtain energy.
According to this question, Nida draws a diagram with insects, birds, and mice. She shows the mice eating grass; hawks, snakes, and toads eating the insects; and foxes, hawks, and snakes eating the birds and mice. The snakes are also eating the toads. This diagram depicts all the possible predators and preys. It shows a complex pattern of food chains, hence, it is a FOOD WEB.

Answer:
Bacteria grows very fast.
Explanation:
There are 1,000,000 bacteria living in a 5 centimeter square means that each centimeter square has 200,000 of bacteria. This figure shows that the bacteria grows rapidly and having very large population in a very little space due to its smaller size. It grows in colonial form and have a very short life cycle. It reproduce through asexual reproduction which is binary fission in which one bacterial cell divides into two cells.

What are two characteristics of DNA?
O Double bonded with hydrogen
O Organic and saturated
O Helix and double stranded
Phosphate and nitrogenous
Explanation:
DNA has three types of chemical component: phosphate, a sugar called deoxyribose, and four nitrogenous bases—adenine, guanine, cytosine, and thymine. Two of the bases, adenine and guanine, have a double-ring structure characteristic of a type of chemical called a purine.
c. Provide one possible explanation for the change in bird numbers and beak characteristics.
Answer:
Evolution
Explanation:
If there is an environmental stressor, then animals will evolve to overcome it.
Birds may begin producing more or fewer offspring depending on how much food is available. If there is more food available, birds will have more offspring. If there is less food available, birds will produce fewer offspring.
Beak characteristics change depending on food options, mating rituals, or environment. A bird will need a narrow beak for most bugs, but it will need a wider and stronger beak for nuts and seeds. A bird's beak may also be used to help interact with its environment. For example, a woodpecker has a strong narrow beak to help it break into tree bark to eat.

Characteristics demonstrate that sea anemones are animals and not plants are;
The cells do not contain a membrane-bound nucleus; that is, they are prokaryotic.The organism consists of cells that perform chemosynthesis.What are sea anemones?. They are soft-bodied, sedentary colourful flower-like animals. They are attached to the sea bed with the help of a fleshy foot.
.Thus, the move of sea anemones is restricted. They are good predators and catch prey with their tentacles. Sea anemones possess features of animals thus, cell wall is absent in their cells

What is a nucleotide? What is an amino acid? What is a simple sugar (glucose)? What do these three share in common?
Answer: The three mentioned substances (nucleotide, amino acid and glucose) are the BASIC UNITS of its various biological macromolecules.
Explanation:
NUCLEOTIDE is defined as the BASIC UNIT or the building block of nucleic acid such as Deoxyribonucleic (DNA) and Ribonucleic (RNA). It contains a sugar molecule, a phosphate group and a nitrogen containing base. They have a variety of functions which include:
--> they are the building blocks of substance that control hereditary characteristics.
--> energy carriers,
--> components of enzyme cofactors, and
--> chemical messengers.
AMINO ACID: This is defined as the BASIC UNIT that makes up the biological macromolecule known as PROTEIN which helps in the growth and repair of worn out tissues of the body.
It is made up of basic amino group, an acidic carboxyl group, and a unique organic side chain.
GLUCOSE: This is also the BASIC UNIT of the biological macromolecule called carbohydrates. They are also called simple sugars which are the body's preferred source of energy in the form of carbohydrates.
