A segment of DNA is represented in the illustration.
Answer:
DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code
Explanation:
As a sequence of nucleotides it is the information for a specific protein carried on the DNA molecule. The correct option is A.
What is nucleotide sequence?The most fundamental understanding of a gene or genome is its nucleotide sequence.
Without having this information, no understanding of how genes function or how evolution works would be complete. It is the blueprint that carries the instructions for developing an organism.
The four nucleotides that make up DNA are adenine (A), thymine (T), guanine (G), and cytosine (C) (C).
The two DNA strands are connected by base pairs, which are formed when the nucleotides (A with T and G with C) bind to one another.
It is the data for a particular protein contained on the DNA molecule as a sequence of nucleotides.
Thus, the correct option is A.

How do cells, tissues, organs, and organ systems work
together in a multicellular organism?
Answer:
Key points. Humans—and other complex multicellular organisms—have systems of organs that work together, carrying out processes that keep us alive. ... Cells make up tissues, tissues make up organs, and organs make up organ systems. The function of an organ system depends on the integrated activity of its organs.

Donald is trying to get through a door but his friend Goofy is blocking the way using 15 N of force. Donald finally pushes on the door with 20 N and gets through knocking Goofy out of the way. Solve for net force.
Answer:
5 N
Explanation:
Goofy is blocking the way with 15 N force and Donald was only able to knock Goofy off using a 20 N force. The net force would be the difference between the applied force of Donald and that of Goofy.
Hence,
20 N - 15 N = 5 N
The net force is, therefore, 5 N.

Answer:
4 genetically different haploid cells
Explanation:
meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell.
4 genetically different haploid cells.
What is Meiosis?
In sexually reproducing organisms, meiosis is a kind of cell division that results in a reduction in the number of chromosomes in gametes (the sex cells, or egg and sperm). Body (or somatic) cells in humans are diploid, meaning they have two sets of chromosomes (one from each parent).
The egg and sperm that combine during fertilization must be haploid, or having only one pair of chromosomes, in order to sustain this state. Each diploid cell divides twice during meiosis to produce four haploid daughter cells, which are the gametes.
Nearly every human cell contains 46 chromosomes, 23 of which come from one of our parents and 23 highly similar chromosomes from the other parent.
Therefore, 4 genetically different haploid cells.

What is one way people have negatively affected land resources?
A) Habitat restoration
B) Urbanization
C) Terrace farming
D) Reforestation
Answer:
b
Explanation:
Urbanization is one way people have negatively affected land resources. Therefore, the correct option is B.
What is Urbanization?The process of urbanization occurs when the percentage of a country's population living in urban areas increases. This is a result of rural-urban migration, which occurs when people move from rural to urban areas in search of better job prospects, social services, and living standards. Urbanization has both beneficial and harmful effects on the environment and society.
On the plus side, urbanization can promote economic growth, better infrastructure, and greater access to social services, including healthcare, education, and social assistance. Additionally, it helps reduce stress on rural communities, which may experience issues of resource scarcity, resource overabundance, and environmental degradation.
Therefore, the correct option is B.
