Answer:

Thymine

Explanation:

Nucleic acids (DNA and RNA) are formed by the union of nucleotides, each of which in turn consists of phosphate, pentose and nitrogenous base.

Nitrogenous bases are classified as purine and pyrimidine as follows:

Purine bases: Adenine (A) and Guanine (G)
Pyrimidine bases: Cytosine (C), Thymine (T) and Uracilla (U)

In both DNA and RNA, the Guanine nitrogen base (G) binds exclusively to cytosine (C). The difference occurs in relation to the other bases: whereas in DNA adenine (A) binds only to thymine (T), in RNA adenine (A) will always be linked to the nitrogenous base Uracila (U).

adenine can form two hydrogen bonds with thymine. adenine-thymine and guanine-cytosine in DNA, and adenine-uracil and guanine-cytosine in RNA.

bonufazy [111]

Answer:

The correct answer is - they are both systems that are performing similar functions.

Explanation:

In the given question there are two different entities that do a similar kind of work or perform similar functions, however, the systems are different as one system involves the manpower of a worker whereas the other system involves the high power of a bulldozer.

The work is similar but the amount of the work varies as manual work done by a worker is less in comparison to the bulldozer.

in reaction a, each sodium atom gives one electron to a chlorine atom. in reaction b, an isotope of oxygen decays to form an iso

vekshin1

The answer is b.reaction b releases more energy than reaction a releases.

The reaction a is an example of a chemical reaction while the reaction b is an example of a nuclear reaction.
Some main differences between the chemical and nuclear reactions are:
- The nuclear reaction releases more energy per gram.
- The nuclear reaction takes place in the nucleus of the atom, while in chemical reactions include electrons.
- In the nuclear reaction, part of the mass is converted into energy, which violates the law of conservation of mass.

Therefore, the nuclear reaction (reaction b) will release more energy than the chemical reaction (reaction a).

The single-celled organism with a nucleus can be categorized into FUNGI OR PROTIST

Living organisms has been classified into six kingdoms namely: Animalia, Plantae, Fungi, Protista, Monera and Archaebacteria.

Among these kingdoms, kingdoms Animalia, Plantae, Fungi, and Protista are all EUKARYOTIC. This means that they possess a true nucleus in their cells.

However, characteristically, among the eukaryotic kingdoms we have, only kingdoms FUNGI and PROTISA contain members that are single-celled.

Hence, a single-celled organism with a nucleus can be categorized into FUNGI OR PROTIST

Can somebody give me the answer for these...

labwork [276]

Answer:

1. Life cycle of a cell starts from

G1 phase - S phase (synthesise phase) - G2 phase - mitosis.

2. By mitosis bcoz it restore nucleo cytoplasmic ratio means ploidy of cell remain same.

3. Bcoz of transformation of normal cells into cancerous cells by Carcinogens present in tobacco.,drugs .etc

4 mitosis occurs in plants animals

Binary fission occurs in bacteria and other single celled organism.

Both give rise to two daughter cells.

5.sex cells (n) are produced by meiosis from gamete mother cells(2n).

6.in meiosis ploidy of cell become half

Means diploid cell form haploid cells

And 4 haploid daughters cells are formed.

In mitosis, ploidy of cell remain same

Means haploid form haploid and diploid form diploid.

1 cell form 2 daughter cells.

Hope this helps you.. Frnd ❤️

What are the two ways that eubacteria can reproduce?

tresset_1 [31]

The two ways through which Eubacteria can reproduce are as follows:

Binary fission and Conjugation.

Thus, the correct option for this question is C.

<h3>What is Eubacteria?</h3>

Eubacteria may be defined as a prokaryotic microorganism that primarily consists of a single cell that lacks a nucleus and contains DNA in a single circular chromosome. It also lacks other membrane-bound cell organelles.

During the process of binary fission, Eubacteria divide into two separate daughter cells through mitosis. While during the process of conjugation, two Eubacteria cells of the same or different species connect using the pili and exchange their genetic material.

Conjugation is partially considered a type of sexual mode.

Therefore, binary fission and conjugation are the two methods through which eubacteria can reproduce. Thus, the correct option for this question is C.
