This is the sequence of protein synthesis and transport of secreted proteins: the first step is rough ER, the vesicle from ER, golgi appartus, the vesicle from golgi, and then finally it goes out of the plasma membrane.
How do the proteins go out of the cell?
The protein is synthesized on the rough ER surface and then enters the ER lumen. The vesicle exits the ER and travels to the golgi apparatus, which contains the protein, where it undergoes further modification. From the golgi, the modified protein goes out of the cell through the vesicle.
Hence, the sequence is rough ER-vesicles from ER- Golgi apparatus, vesicles from Golgi apparatus- and plasma membrane.

Contralateral means that the crossed extensor reflex takes place on the side of the body that is opposite from the stimulus. Afferent nerve fiber branches travel from the stimulated side of the body to the opposite side of the spinal cord to cause this reflex.
A scientist is attempting to provide support for the hypothesis that RNA was the first genetic material. Which of the following would be a workable alternate hypothesis?
(A) RNA, like DNA, is a carrier of genetic information and contains the nitrogen bases adenine, guanine, and cytosine.
(B) RNA can be observed to self-replicate without the assistance of proteins, while DNA always requires protein-based enzymes to replicate.
(C) RNA exists in both single-stranded and double-stranded configurations; however, it is less stable compared with DNA.
(D) Transfer RNA and ribosomal RNA are products of transcription, but they are not translated as is mRNA.
Answers
RNA can be observed to self-replicate without the assistance of proteins, while DNA always requires protein-based enzymes to replicate. Thus, option B is correct.
What is RNA?RNA has a nucleic acid that has a single-stranded structure. RNA is also a genetic material. It helps in coding, decoding, and gene expression. RNA was the first genetic material and RNA can be replicated by itself. It has evolved all the methods that are necessary to store genetic information.
Thus, the hypothesis (B) RNA can be observed to self-replicate without the assistance of proteins, while DNA always requires protein-based enzymes to replicate is the correct option.
Therefore, RNA can be observed to self-replicate without the assistance of proteins, while DNA always requires protein-based enzymes to replicate. Thus, option B is correct.

Which of the following statements is true regarding the absorptive and postabsorptive states? Check all that apply The absorptive state only lasts for approximately 30 minutes after a meal. During the absorptive state nutrients may be used immediately to meet energy demands. Glycogenolysis is most likely utilized to meet energy demands during the postabsorptive state, Blood glucose drops dramatically during the absorptive state. Gluconeogenesis most likely occurs at least 4 hours after the last meal.
Answers
The statements that are true regarding absorptive and post-absorptive are -
option (2): During the absorptive state nutrients may be used immediately to meet energy demands
option (3): Glycogenolysis is most likely utilized to meet energy demands during the post-absorptive state
option (5): Gluconeogenesis most likely occurs at least 4 hours after the last meal.
What is absorptive and post-absorptive state?Absorptive stage = fed state and post absorptive stage = fasting state.
The absorptive state is the time when ingested nutrients enter the circulation and part of these nutrients meet the body's energy needs while the rest is stored. The post-absorptive stage is the time when the GI system is depleted of nutrients and the body must rely on stored energy.
Option 2: Nutrients can be utilized directly to fulfill energy demands during the absorptive period.
Explanation: Taking a glucose solution while exercising provides athletes with instant energy. As glucose begins to be absorbed from the mouth.
Option 3: Glycogenolysis is most likely used to supply energy requirements during the post-absorption period.
Explanation: During the post-absorptive phase, the liver glycogen begins to break down and create glucose for the body's energy source.
Option 5: Gluconeogenesis happens at least four hours after the last meal.
Explanation: Our bodies require extra energy after around four hours of absorption. The gluconeogenesis process then begins.
Whereas,
Option 1: The absorptive condition lasts 4 hours, not 30 minutes.
Option 4: Blood glucose levels rise sharply during the absorptive period and do not fall.

Answers
A person with different numbers of copies of the same repeat at the same locus on both homologs is said to be heterozygous for the gene variant.
What is a heterozygous gene variant?A heterozygous gene variant is any gene that contains two different alleles for the same locus, in opposite when it contains the same allele which is known as a homozygous individual.
A gene variant is a given allele for a particular locus, which is well known to have a different nucleotide combination in the specific fragment of the DNA molecule that is known to contain the instruction to create all types of proteins observed in an individual.
Therefore, with this data, we can see that the heterozygous gene variant is based on the different alleles for the same gene which is encoded by different nucleotide sequences in such sequence.

Which statements are observations that Darwin made on his voyage?
(Select all that apply.)
Answers
One theory is that evolution takes place. In other words, organisms undergo gradual change. As offspring from ancient common ancestors diverged, life on Earth has transformed.
What is Voyage in Darwin?The second hypothesis proposes that natural selection drives evolution. Natural selection is the process through which living creatures that possess advantageous qualities have more offspring than those that do not. As a result, over time, the characteristics of living things change.
Most people in Darwin's day thought that all species were formed simultaneously and then stayed unchanging. Additionally, they thought Earth was only 6,000 years old. Darwin's theories so transformed biology.
Darwin embarked on a scientific journey in 1831 when he was only 22 years old on board the HMS Beagle. He served as the expedition's naturalist. Wherever the expedition went ashore, it was his duty as a naturalist to examine and gather samples of plants, animals, rocks, and fossils.
