The correct answer is: They are released into the cytosol.
A a sequence consisting of 5-30 hydrophobic amino acids on the N-terminus, which is called signal peptide or signal sequence is responsible for directing the transport of the synthesized protein. Proteins that contain such sequence are destined for secretion form the cell (vesicular), for the plasma membrane, the lumen or membrane of either the (ER), Golgi or endosomes. So, when the protein lack the sequence, it is released in the cytosol.
This is a membrane-bound organelle in eukaryotic cells that is the production and transportation of proteins.
The answer is: endoplasmic reticulum.
This organelle is composed of membrane-enclosed structures that look like tube or sacs known as cisternae. Its roles are role in the production, processing, and transport of proteins and lipids. There are two forms of endoplasmic reticulum (ER):
•Rough ER-covered with ribosomes which are the side of protein synthesis
•Smooth ER-involved in synthesis of lipids and steroids
From ER, newly formed proteins are transported to lysosomes, Golgi apparatus, plasma membrane…
Which statements describe transform boundaries? Check all that apply. (There is more than one correct answer.) Rift valleys are formed.
Mountains are created.
Faults form in the lithosphere.
Plates move toward each other.
Plates slide in opposite directions.
The correct answers are:
- Faults form in the lithosphere;
- Plates slide in opposite directions;
The transform plate boundaries are plate boundaries where the two or more plates are sliding past each other, moving in opposite directions. Because of the sliding, a lot of pressure is created on the plate boundary, so the earthquakes are a common occurrence. Also, something that is a characteristic of this type of plate boundary are the faults, to be more specific, transform faults. The transform faults are parallel to the plate boundary, and it can be a single one, or multiple faults parallel to one another. Their depth also can vary, from few meters to several tens of meters, or even more.

A) bivalves is the answer
The lowest temperature possible in nature is
the lowest possible temperature in nature is absolute zero, which defines 0 degrees Kelvin (-273.15 degrees C. or -459.67 degrees F.) If by 'nature' you mean ANYWHERE outside a laboratory, intergalactic space would probably offer the lowest temperatures in the known Universe.
hope this helps :)
The duodenal ampulla receives secretions from the

Which of the following types of fungi are typically unicellular, lack heterokaryotic cells, and occasionally produce rhizoids? Select all correct choices. basidiomycetes
chytrids are saphrotrophs, and have chitin cell walls and a posterior whiplash flagellum. They reproduce with zoospores that are capable of active movement through aqueous phases. For most members of chytrid group, asexual reproduction occurs through the release of these zoospores derived through mitosis. In some groups of chytrids, sexual reproduction is achieved through the fusion of isogametes. Chytrids are coenocytic with no distinction between individual cells. The filaments are long and tubular with a cytoplasm lining and large vacuole in the center. These single-celled organisms have branching hyphae with rhizoids.
Oxygen is the final electron acceptor for cellular respiration. What is the final electron acceptor in the light reactions of photosynthesis?
Photosynthetic electron transport chain in plant cells is used for extracting sunlight energy via redox reactions through the process of photosynthesis. This process occurs in chloroplast (thylakoid membrane), where light energy is transformed into chemical energy, that leads to the conversion of water to oxygen and NADP+ (final acceptor) to NADPH with transfer of H+ ions across chloroplast membranes. Formed H+ gradient is used for the ATP synthesis.

Blood returning from the lungs enters theA. Left atriumB. Left ventricleC. Right atriumD. Right ventricleE. Aorta

Which of the following structures in females is analogous in function to the vas deferens in males? A. urethra
The answer is B) oviduct
Which of the following surrounds the individual muscle cell? a) perimysium
Muscle cell also called myocyte, mmusce fiber is enveloped with thin connective tissue layer of collagen and reticular fibers which is called endomysium. Muscle fibers are organized in bundles called fascicles which are covered with the perimysium (middle layer of connective tissue).
Epymysium is irregular connective tissue that covers the whole muscle.
True or false? Axon diameter and degree of myelination determine nerve impulse conduction velocity.
The myelin sheath covers many axons in central nervous system (CNS) ( by oligodendrocytes) and in the peripheral nervous system (PNS) (by Schwann cells). Their function is to insulate axons and to increase the speed at which information travels from one nerve cell to another.
Nerve conduction velocity is specific to each individual and depend largely onboth an axon's diameter and the level to which that axon is myelinated.
Which of the following statements correctly describes how Mendel accounted for the observation that traits had disappeared in the F1 generation and then reappeared in the F2 generation? A) Traits can be dominant or recessive, and the recessive traits were "hidden" by the dominant ones in the F1.
B) New mutations were frequently generated in the F2 progeny, causing traits that had been lost in the F1 to reappear in the F2.
C) Members of the F1 generation had only one allele for each trait, but members of the F2 had two alleles for each trait.
D) The mechanism controlling the appearance of traits was different between the F1 and the F2 plants.
A) Traits can be dominant or recessive, and the recessive traits were "hidden" by the dominant ones in the F1.
Mendel discovered the fundamental theory of heredity: that inheritance involves the passing of genes (he called it discrete units of inheritance), from parents to offspring. Those genes are with two alleles in the genotype, one inherited from the father and other inherited from the mother.
When he cross-bred pure-bred parent (always produced offspring identical to the parent) plants dominant traits were always seen in the offspring, while recessive traits were hidden until the first-generation (F1) hybrid plants were left to self-pollinate. Mendel also noticed that in second-generation (F2) of the offspring 3:1 was ratio of dominant to recessive traits.
At what point in the light-capturing reactions is the electromagnetic energy of light converted into chemical energy? Where does this occur?
The conversion of light energy to chemical energy first occurs when electrons are transferred from excited photopigments to an electron carrier in a photosystem (pigments together with proteins organized into complexes and located in the thylakoid membranes of chloroplasts).
The light-dependent reactions is one of the two successive phases that occur during photosynthesis (other is light-independent reactions). The light-dependent reactions use sunlight energy (electromagnetic radiation) to make the energy storage molecule ATP and the reduced electron carrier NADPH. In the light-independent reactions (also called Calvin cycle), CO2 is absorbed and fixed in order to build three-carbon sugars (glyceraldehyde-3-phosphate) and this process is fueled by, ATP and NADPH from the light reactions.

cecum; transverse colon; sigmoid colon; rectum
Large intestine is the last part of the alimentary canal (digestive tract) and it is the place where water is absorbed and remaining waste material stored and ready to be pull out. The large intestine can be divided into f five sections:

•the transverse colon,
•the descending colon,
•the sigmoid colon,
