a typical human chromosome contains about how many nucleotides in its dna?
Answer:
50 million nucleotide pairs
The typical human chromosome contains 50 million nucleotide pairs
in its DNA.
What is DNA?Deoxyribonucleic acid (DNA) is a polymer composed of two polynucleotide chains that coil around each other to form a double helix carrying genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses. DNA and ribonucleic acid (RNA) are nucleic acids. Alongside proteins, lipids and complex carbohydrates (polysaccharides), nucleic acids are one of the four major types of macro molecules that are essential for all known forms of life.
Hence, The typical human chromosome contains 50 million nucleotide pairs.

Which scenario best describes natural selection?
a species of flower develops a gene that results in a more attractive nectar causing more pollinators to be attracted
wheat plants are selected for their ability to produce the most wheat germ
a bacteria exposed to radiation acquires a mutation
a hurricane occurs and kills 70% of the members of a rodent species
Answer: A species of flower develops a gene that results in a more attractive nectar causing more pollinators to be attracted
Explanation: I think it’s that one and sorry if I’m wrong but to me the other choices don’t seem to fit as a hurricane kills 70% isn’t helping any organisms adapted and the other two choices no organisms is adapted but the first, the flowers have to adapt as they develop a new gene and it also affects pollinators
What is the difference in the structure of the cell walls of gram-positive and grarn-negative
bacteria?
Answer:
The major difference between Gram-positive and Gram-negative peptidoglycan involves the thickness of the layers surrounding the plasma membrane. Whereas Gram-negative peptidoglycan is only a few nanometers thick, representing one to a few layers, Gram-positive peptidoglycan is 30–100 nm thick and contains many layers.

An example of a communicable disease is
A - cancer.
B - chronic respiratory disease.
C- diabetes.
D -giardiasis.
Answer:
D giardiasis is the correct answer :)
An example of a communicable disease is giardiasis, which is in option D. Giardiasis is an example of a communicable disease. It is caused by a microscopic parasite called Giardia lamblia.
This disease affects the digestive system, causing symptoms such as diarrhea, abdominal cramps, bloating, and nausea. It is typically transmitted through the ingestion of contaminated food or water that has been contaminated with the parasite. Chronic respiratory disease includes conditions such as asthma, chronic obstructive pulmonary disease (COPD), and bronchitis, which are usually caused by long-term exposure to irritants or genetics and are not directly communicable.

Which of the following is a disadvantage of genetic engineering?
May cause negative side effects
Cannot create new organisms
Reduces the nutrition value of food
Increases the scarcity of food in the world
Answer:
may cause negative side effects
Explanation:
Answer:
May cause negative side effects.
Explanation:
I took the test
Genetic Engineering is used to put genes from one organisms into another. The new organism can reproduce. And while it may seem like it's the answer the nutrition value and scarcity of food is in no way impacted. It's not like cloning. Where more are being created in large amounts with similar diets. They can be cross-pollinated with organisms with different diets. So the only obvious answer would be the negative side effects.

21. Three different processes are occurring in the drawing below. Name each process and describe it.
The three different processes that are occurring in the above drawing are:
1. Process A: Diffusion.
2. Process B: Facilitated diffusion.
3. Process C: Active transport.
Cell transport refers to the movement of ions, molecules, or substances across the cell membrane, either into or out of the cells of a living organism.
From the above diagram, the three (3) different processes that are occurring are:
1. Process A: Diffusion.
Diffusion refers to the movement of gas molecules from a region of high concentration (top) to a region of lower concentration (bottom) until an equilibrium is attained or reached.2. Process B: Facilitated diffusion.
Facilitated diffusion refers to the movement of substances or gas molecules across a cell membrane from a region of high concentration (top) to a region of lower concentration (bottom), especially through the help of transport protein.3. Process C: Active transport.
Active transport involves the movement of substances across the cell membrane from a region of lower concentration to a region of higher concentration, against a concentration gradient and in the presence of oxygen.Read more: https://brainly.com/question/18646362
