Answer:
The correct answer is: They remain in the cytosol.
Explanation:
Eukaryotic proteins are made through a process called Translation, which always starts at the cytosol (except for the proteins that are made in the mitochondria).
While Translation is taking place, the peptide that is being synthesized is checked for molecular tags that will lead to a re-routing to another destination: proteins that have an amino sequence called 'signal peptide' will be sent to the endoplasmic reticulum for its translation to continue - the proteins that go this route are meant to be part of the endomembrane system, after that they can be bounded to the ER, the Golgi apparatus or the lysosomes.
Unlike the proteins mentioned before, there are proteins that will have no signal peptide - this means that they are meant to finish Translation in the cytosol. Some of these proteins will acquire a signal tag that will lead them to the nucleus or the mitochondria, for example, but if they don't they will stay permanently in the cytosol to perform their tasks in that place.

NEED HELP ASAP!
The Doppler Effect talks about the frequency of sound and light as the source and person move. So, When light waves are emitted by a moving source, scientists can measure = the Doppler effect.
Cosmic microwave background radiation has the word "cosmic" in it, so you can assume it has to do with space automatically. There is radiation in space too, so I'm pretty sure that The extremely low temperature of outer space can be explained as = cosmic microwave background radiation.
Particle accelerators are these big machines that usually smash protons/electrons together, so Scientists smash together tiny bits of matter using = particle accelerators.
And now, by process of elimination and because the Big Bang Theory talks about the creation of Earth, we know that Scientists extrapolate backwards in time to derive = the Big Bang Theory.

Leukemia
A type of cancer which affects the production and function of blood cells. This causes swollen lymph nodes, recurrent nosebleeds, tiredness, frequent infections, weight loss, bleeding, and bone pain. Leukemia symptoms vary, depending on the type of leukemia. Common signs and symptoms of leukemia include:
Swollen lymph nodes especially in the neck and armpits
Experience pain in bones
Night sweats - excessive sweating, especially at Night
Weakness and fatigue
Rapid weight loss
Red spots on the skin
Bleeding and bruising easily
Fever or chills
Frequent infections
Causes
The exact cause is not known. Hereditary and environmental factors may play a role in developing the disease.
The risk factors include:
Mutations in the DNA are frequently a major cause.
Sometimes chromosome translocation can also promote activation of oncogenes (the cancer inducing genes) and this can lead to disease progression.
Exposure to certain chemicals and radiation can also induce cancer.
ii) Explain briefly how these features contribute to the efficiency of photosynthesis?
Answer:
here's your answer
Explanation:
the estimated maximum energy efficiency of photosynthesis is the energy stored per mole of oxygen evolved, 117/450, or 26 percent.
Consequently, plants can at best absorb only about 34 percent of the incident sunlight. The actual percentage of solar energy stored by plants is much less than the maximum energy efficiency of photosynthesis. An agricultural crop in which the biomass (total dry weight) stores as much as 1 percent of total solar energy received on an annual areawide basis is exceptional, although a few cases of higher yields (perhaps as much as 3.5 percent in sugarcane) have been reported. There are several reasons for this difference between the predicted maximum efficiency of photosynthesis and the actual energy stored in biomass. First, more than half of the incident sunlight is composed of wavelengths too long to be absorbed, and some of the remainder is reflected or lost to the leaves

Discuss the sensory neurons for vision. What are the two
types of sensory neurons for vision? Where are they located?
What are their functions in the eye? What path does visual
input take AFTER reaching the sensory neurons (be specific,
outlining the entire path to the destination point of the brain)?
Answer:
Olfactory sensory neurons (OSN).
Explanation:
Olfactory sensory neurons (OSN) are the sensory neurons that is responsible for vision. Photoreceptors and olfactory sensory neurons (OSN) are the two types of sensory neurons for vision. Both olfactory sensory neurons (OSN) and photoreceptors is responsible for the receiving of photons and enable us to see things. The right half of the visual field will travel in the left optic tract, while on the other hand, the stimuli from the left half of the visual field will pass through the right optic tract.
Answer: The two types of sensory neurones are the CONES and RODS. Their functions are better outlined below
Explanation:
The CONES and RODS are the sensory neurones ( photoreceptors) of the eye which are located in the retina.
The RODS: They are extremely sensitive and can detect light of very low intensity. They also perceive light in black and white. They, therefore, play an important role in dim light.
The CONES: They function in bright light and are responsible for colour vision.
The path visual input take AFTER reaching the sensory neurons is as follows:
--> the rods and cones are stimulated
--> A pattern of electrical impulses is sent to the brain through the optic nerve which interprets it, drawing on past experience.
The brain tells us that the object is upright and gives us it's real size and distance from the eye. We, therefore, see the object as it actually is, and not as the image formed on the retina.

Normal diploid somatic cells of the mosquito Culex pipiens contain six chromosomes. The G1 nucleus of a mosquito cell contains 3.0 x 10^-12 grams of DNA. How much nuclear DNA would be expected in metaphase I of meiosis?
a. 6.0 x 10^-12 g.
b. 1.5 x 10^-12 g.
c. 12 x 10^-12 g.
d. 3.0 x 10^-12 g.
e. 0.75 x 10^-12 g.
Answer:
a. 6.0 x 10^-12 g.
Explanation:
The interphase is the previous step before the cell divission occurs. The interphase is formed of the G1, S, and G2 stages.
• During the G1 stage, it occurs a high intense biochemical activity. The cell duplicates its size, and the organelles and other molecules and cytoplasmatic structures duplicate too. Some structures, such as microtubules and actin filaments, are synthesized from zero. The endoplasmic reticulum increases in size and produces a membrane for the Golgi apparatus and vacuoles, lysosomes, and vesicles. During this stage, the pair of centrioles separate, and each centriole duplicates. Mitochondria and chloroplasts also replicate.
• During the S stage occurs the DNI replication process. It also occurs the synthesis of histones and other associated proteins. This is the only stage where the DNI molecule is replicated.
• G2 stage is the final one before the cellular division. Here begins the slow process of DNI condensation. Duplication of centrioles completes. Structures such as spindle fibers are assembled.
Through the process of Meiosis, a diploid germ cell (2n) divides and originates four daughter cells with a haploid chromosome number (n). Each daughter cell has half of the chromosomes of the original one. Meiosis is completed in two phases. During the first phase, and after replication, occurs the chromosome´s reduction division. During the second phase, the cell suffers a new, not reductive division.
1. In the first phase, Meiosis I:
Prophase I: Chromosomes condensate and became visible. Occurs crossing-over between homologous chromosomes. Crossin-over makes the daughter cells to be genetically different from the original one. Metaphase I: The pairs of homologous chromosomes randomly align in the equatorial plane. Anaphase I: occurs the independent separation of homologous chromosomes that migrate to opposite poles of the cell. This separation generates different chromosomal combinations in the daughter cells. Telophase I: Each of the homologous pairs chromosomes is already in the corresponding poles, and the nuclear membrane forms again in each pole.2. In the second phase, Meiosis II:
Prophase II: Chromosomes condensate again and become visible. Metaphase II: Chromosomes join the spindle apparatus and migrate to the equatorial plane, where they randomly line up. Sister chromatids are holden together until they reach the Anaphase. Anaphase II: Centromeres divide, chromatids get separated, and each of them goes forward an opposite cellular pole. Telophase II: Once in the poles, the chromosomes became lax again, and cytokinesis occurs.In the exposed example, DNI in the G1 nucleus of a mosquito cell still has not suffered replication (3.0 x 10^-12 grams). The replication process occurs during the S stage, which follows the G1 stage. After the S stage, the cell has 6.0 x 10^-12 g of DNI.
During meiosis, the reduction in chromosomes number occurs in anaphase where homologous chromosomes migrate to different poles. But during metaphase I, the cell still has 6.0 x 10^-12 g of DNI.
Two of the five types of taste buds are activated by directly hypopolarizing the taste buds; i.e. do not involve a second-messenger pathway. The tastes that activate these receptors are:
Answer: salty and sour
Explanation:
