Answer:
Option (1).
Explanation:
DNA (deoxyribo nucleic acid ) is the genetic material present in all the organisms except some viruses. DNA structure follows the Chargaff's rule.
Accoprding to Chargaff's rule, the ratio of purines to pyrimidines in a DNA molecule is equal to 1. The amount of guanine is nearly equal to the amount of cytosine whereas the amount of thymine is nearly equal to the amount of adenine.
Thus, the correct answer is option (1).
B) only animal cells.
C) only plant cells
Answer:
A) all eukaryotic cells
Answer:
I think A) all eukaryotic cells.
Explanation:
b. 9 billion people.
c. 10 billion people.
d. Humans do not have a carrying capacity
Answer:
Transduction
Explanation:
Among the three types of gene transfer in bacteria, transduction does not require physical contact between the two bacteria cell. Viruses that infect bacteria accidentally move pieces of chromosomal DNA from one bacterium to another. These viruses that infects bacteria are called bacteriophages.
Simply put, transduction is a process of genetic recombination in bacteria which involves the incorporation of the genes of a host cell (bacterium) into the genome of a viral cell (bacteriophage) and then conveyed to another host cell when the bacteriophage infects it. The process of transduction is of two types; generalized and specific depending on whether any gene or specific gene is transduced respectively.
The aim of these viruses when they infect bacteria cell is to harness the ability of bacteria to replicate, transcribe and translate their genetic material and use it to procreate into many virons or complete their viral particle.
B.Living organisms create order by using energy from the sun.
C.Living organisms create order locally, but the energy transformations generate waste heat that increases the entropy of the universe.
Answer:
C.Living organisms create order locally, but the energy transformations generate waste heat that increases the entropy of the universe.
Explanation:
Entropy is a concept of thermodynamics that measures the disorder of particles in a physical system. Living organisms create some disorder through reactions that generate waste heat so that through heat-shaped energy, organelles capable of generating macromolecules, organelles, cells, tissues, and higher-order complex structures are ordered.
b. contains a KDEL sequence near its C-terminus.
c. has a membrane-spanning domain length equals the
d. thickness of the cis-Golgi membrane.
e. was imported directly into the cis-Golgi posttranslationally.
f. has a mannose-6-phosphate tag.
Answer:
C. has a membrane-spanning domain length equals the thickness of the cis-Golgi membrane.
Explanation:
Secretory pathway is the pathway that transport proteins to the cell surface membrane. For this, the membrane proteins are labeled radioactively and move through the various organelles to carry the proteins to the surface membrane.
After six hours, all the radioactivity is concentrated in the cis-Golgi apparatus this means that The protein carries membrane-spanning domain which widens or make the cis-Golgi menbrane thick.
Hence, the correct answer is "C".
B. A student makes a mistake when measuring volume.
C. The hypothesis was unrelated to the research question.
D. Temperature readings are made late in the day, when everyone is tired and eager to go home.
