which sequence accurately describes the path traveled by a new protein from when it first starts to be translated to its release from the cell?
Answers
The sequential pathway of a protein from it first starts to be translated to its release from the cell is cytosol > ER > Golgi > vesicle > plasma membrane > external environment. These proteins are synthesized in the ribosomes.
The exported proteins are synthesized (i.e., translated) in the ribosomes of the cytosol that bound to the endoplasmic reticulum in order to enter into the endomembrane system.
Subsequently, extracellular proteins undergo processing in the Golgi apparatus, which is connected to the rough RE by transport vesicles.
Finally, these proteins pass through transport vesicles in order to be exported from the cell by endocytosis.

A reflex in which a contralateral extensor muscle is contracted is called a?
Answers
The reflex you are referring to is known as the crossed extensor reflex. It is a protective mechanism exhibited by the body in response to a potentially harmful stimulus.
When this reflex is triggered, the flexor muscles on one side of the body contract, withdrawing the limb from the stimulus. Simultaneously, the extensor muscles on the opposite side of the body contract, providing support and stability to maintain balance. This reflex allows for the body to respond swiftly and effectively to external threats, ensuring the preservation of equilibrium and preventing potential injuries. The crossed extensor reflex is an important component of the complex network of reflex actions in the human body.

Which set of conditions would most likely cause a change in gene frequency in a population that reproduces sexually
Answers
Small population size is most likely to result in changes in allele frequencies in a population. So, the correct option is (B).
The relative frequency of an allele (gene variant) at a specific locus in a population, expressed as a fraction or percentage, is known as allele frequency or gene frequency. It is the proportion of all chromosomes in the population that carry that allele divided by the entire population or sample size. Microevolution is the change in allele frequencies that happens within a population over time.
Given the given facts:
A specific location on a chromosome and a specific allele at that siteA population of N people with ploidy n, which means that each person has n copies of each chromosome in their somatic cells (e.g. two chromosomes in the cells of diploid species)In the population, the allele is found on I chromosomes.Learn more about gene frequency to visit this link

The scapula and humerus serve as the proximal attachments for the muscles that flex and extend the elbow
What are Elbow Bones?
The ulna is much larger proximally than the radius (Fig. 6.1), but distally the radius is much larger than the ulna (see Fig. 7.1 in p. 170). The scapula and humerus serve as the proximal attachments for the muscles that flex and extend the elbow. The ulna and radius serve as the distal attachments for the same muscles. The scapula, humerus and ulna serve as proximal attachments for the muscles that pronate and supinate the radioulnar joints. The distal attachments of the radioulnar joint muscles are located on the radius.

The world's atmosphere can hold more moisture as it warms. As a result, the overall number of heavy storms has likely increased since midcentury due to global warming. True or false?
Answers
Answer:
True.
Explanation:
Yes, the number of heavy storms has increased due to global warming because of the holding power of moisture by the atmosphere due to higher temperature. When the air is warmed, the air can hold more water at that temperature so due to more holding power of moisture by the air the number of storms increases. One NASA study supports that global warming is causing the increase in number of extreme storms especially in the tropical ocean.

The cranial nerve responsible for movement of the medial rectus, superior rectus, inferior rectus and inferior oblique eye muscles is the ________ nerve. group of answer choices hypoglossal
Answers
The cranial nerve responsible for the movement of the medial rectus, superior rectus, inferior rectus, and inferior oblique eye muscles is the oculomotor nerve (cranial nerve III). The correct answer is option C.
The oculomotor nerve (cranial nerve III) is one of the twelve cranial nerves that originate in the brainstem. It is responsible for the control of most of the movements of the eye, including constriction of the pupil, focusing the lens of the eye, and the coordinated movement of several extraocular muscles that control eye movement.
The oculomotor nerve emerges from the midbrain and travels through the cavernous sinus, a large venous sinus in the skull, before entering the orbit through the superior orbital fissure. In the orbit, the nerve branches into several smaller nerves that innervate the muscles of the eye.
Damage to the oculomotor nerve can result in a number of different symptoms, depending on which portion of the nerve is affected. These can include drooping eyelids (ptosis), double vision (diplopia), and difficulty moving the eye in certain directions. In some cases, damage to the oculomotor nerve can be a sign of a more serious underlying condition, such as a brain tumor or an aneurysm.

Answers
Answer:
Explanation:
Antibiotic resistance is when the bacteria develop resistance to antibiotics. Antibiotic resistance will affect human populations is no action is taken by our Agricultural system because bacteria itself develop antibiotics resistance and these causes infections on humans and animals. The infections caused by antibiotics resistance bacteria are difficult to treat than those that are not caused by it. These the result in higher cost of medical treatment and treatment of animals, prolonged hospital admission and these can also lead to increased mortality or increase rate of death of Agricultural animals. When there is high mortality of Agricultural products due to this, there won't be enough consumption of these by humans and also there can be passage of these infections to human which can result to mortality.

The Rock Cycle is Earth's great recycling process where igneous, metamorphic, and sedimentary rocks can all be derived from and form one another.Older rocks are destroyed by weathering processes and the remains are recycled into new rocks. This cycle from old rocks to new rocks is called the rock cycle. The interaction between the tectonic and the hydrologic systems causes constant recycling of the materials of the Earth's crust.
if planet y orbits the sun bur does not rotate on its axis at all how long would a daybbe on planet y
Answers
If Planet Y does not rotate on its axis at all, then one day-night cycle on the planet would take as long as one full orbit around the Sun.
This is because the definition of a day is the time it takes for one complete rotation on its axis, and if Planet Y does not rotate on its axis, it does not have a day.
Assuming that Planet Y's orbit around the Sun is circular and has a period of one Earth year (365.25 Earth days), then one day on Planet Y would also be 365.25 Earth days long. Therefore, a year on Planet Y would also be 365.25 Earth days long, and the planet would have one day and one night each year.
What is an orbit?
An orbit is the path that an object takes as it moves around another object due to the influence of gravity. In astronomy, the most common example of an orbit is the path that a planet takes as it revolves around a star. Orbits are governed by the laws of motion, particularly Kepler's laws of planetary motion, which describe how the gravitational force between two objects affects their motion.

A transcription factor should have at least two DNA binding domains and one activation domain in order to become functionally active
Answers
It is false that A transcription factor should have at least two DNA binding domains and one activation domain in order to become functionally active.
What is transcription factor?
A transcription factor is a protein that, by binding to a particular DNA sequence, regulates the pace at which genetic information is transferred from DNA to messenger RNA. Proteins called transcription factors help turn certain genes "on" or "off" by attaching to surrounding DNA. A gene's transcription is increased by transcription factors that serve as activators. Repressors lessen transcription.
Therefore, transcription factor just need to have a DNA to help bind domains.

Does the relationship between BMI and body fat exist?However, because it does not directly measure body fat, BMI is not a precise measurement.
