The urine volume decreased when the solute gradient in the interstitial
space was increased.
The solute gradient in the interstitial space being increased means more
absorption of compounds into the bloodstream and vice versa. When this
occurs, the constituent of urine decreases.
The decrease in the urine components brings about a decrease in its
volume also due to increased absorption taking place.

Explanation:
The muscle weakness of myasthenia gravis results from loss of acetylcholine receptors in the end-plate membrane. the motor neuron action potential being too small to shock the muscle fibers. insufficient acetylcholine release from presynaptic vesicles. excessive acetylcholinesterase that destroys the neurotransmitter. All of the answers probably contribute to the muscle weakness.
Answer:
The correct answer is ''loss of acetylcholine receptors in the end-plate membrane.''
Explanation:
Myasthenia gravis represents a human autoimmune disease. The neuromuscular junction abnormalities that occur in this disease are due to antibody-mediated processes. A reduction in the number of functional acetylcholine receptors on the postsynaptic membrane was established to contribute to the physiological abnormalities of myasthenia gravis. The reduction in receptors is due to immunological alterations directed against the acetylcholine receptor. Normally, when acetylcholine binds to its receptor, it opens allowing the rapid entry of cations, especially sodium. With this, the depolarization of the postsynaptic region of the muscle fiber occurs. Although acetylcholine is normally released in myasthenia gravis, it is not capable of causing an action potential in the muscle sufficient to initiate or weaken contraction. In patients with myasthenia gravis, failure to activate muscles is responsible for myasthenic fatigue. Most patients have elevated serum titers of antireceptor antibodies, which in turn accelerate receptor degradation.
The consensus is that the coelacanths and lungfishes (Sarcopterygii) represent an evolutionary link between ray-finned fishes and tetrapods. What is the major feature in the Sarcopterygii that supports this hypothesis?
Answer:
Choana, paired fins with a fleshy base over a bony skeleton, persisting notochord, 2 dorsal fins and nares.
Explanation:
Sarcopterygii also known as lobe-finned fishes which usually possess a choana, paired fins with a fleshy base over a bony skeleton, persisting notochord, 2 dorsal fins and nares are present internally. The lungfishes are considered the closest living relatives of tetrapods because of the presence of some common features. The African lungfish has epithelial crypts located at the base of the lamellae of the olfactory epithelium that express markers of the vomeronasal receptors in tetrapods.

Single Strand Binding Proteins are responsible for:
A. keeping the strands separated during replication.
B. unwinding and separating the DNA strands.
C. adding the new bases.
D. linking the short sections of the lagging side.
Reset Selection
Answer:
A. keeping the strands separated during replication
Explanation:
Prior to the process of DNA replication, the double-stranded DNA must first be separated into single strands by an enzyme called DNA helicase. This is done so that each DNA strand can serve as template for the synthesis of another.
After the unwinding and separation, the single strands still need to be kept apart during the synthesis of new nucleotides by DNA polymerase. This role of keeping the strands separated during replication is carried out by SINGLE STRAND BINDING PROTEINS.

Todos los miembros de dicha familia tienen simpatía por las mismas ideas políticas
Answer:
¿todos los miembros de dicha familia tienen simpatia por las mismas ideas políticas? En las últimas elecciones presidenciales, ¿todos los miembros de dicha familia votaron por el mismo partido?¿Puedes preguntarles cómo votaban los integrantes de esa familia hace veinte años, y hace cincuenta años? ¿Qué ha cambiado? Escribe en tu cuaderno tus averiguaciones
Explanation:
Mi familia tiene diferentes ideales políticos y por eso votaron por diferentes partidos, antes el proceso era manual
En las elecciones actuales les he preguntado a los miembros de mi familia y no todos votaron por el mismo partido político unos creen en uno de los partidos políticos y otros creen en otros. Por lo tanto no todos simpatizan con las mismas ideas políticas
Anteriormente se votaba por medio de un papel escrito, entonces el proceso es mucho más lento y menos automatizado que con maquinas
No, cada familiar tiene una idea política distinta.
-no votaron por el mismo partido político pues siempre algunos presidentes hacen promesas y no las cumplen.
-las votaciones siempre las han realizado por numero de DUI, en institutos o en las calles frente a las alcaldías, tenían que buscar el numero de urna en la cual estaban asignados.
-el cambio a sido la tecnología y el voto residencial, pues con la tecnología se ha hecho mas fácil el cuento de los votos y el voto residencial a permitido que se les facilite asistir al centro de votación.

The compound 2,4-dinitrophenol (DNP) is a lipid soluble compound that has been used as a weight loss agent. It functions this way by causing the inner mitochondrial membrane to become leaky with respect to protons. Which result might be expected if cells treated with DNP were examined in detail
Answer:
ATP production would be slower in these cells than in untreated cells
Explanation:
Oxidative phosphorylation is the third stage of cellular respiration, which occurs in the mitochondria of animal and plant cells. Oxidative phosphorylation represents the most efficient pathway to generate energy in animal cells by the production of Adenosine triphosphate (ATP) as a consequence of the transfer of electrons from nicotinamide adenine dinucleotide (reduced form) (NADH) or flavin adenine dinucleotide (reduced form) (FADH2) to molecular oxygen (O2) through a sequential series of electron carriers. The 2,4-Dinitrophenol (DNP) poison is an uncoupler of oxidative phosphorylation that carries protons across the mitochondrial membrane, thereby leading to a rapid consumption of energy without the production of ATP. This mitochondrial uncoupler (DNP) has been used as a dieting drug during the 30's decade (1930), but was rapidly banned due to its side effects, which include, among others, tachycardia, hyperthermia, tachypnea, and metabolic acidosis.
A scientist wishes to create bacterial colonies on an agar plate for observation of growth. Unfortunately, directly adding bacteria from the original culture results in too many bacterial colonies to count. In order to create a solution of proper bacterial concentration for observation, the scientist performs a three-step 1:100 serial dilution of the original bacterial culture. What is the dilution factor of the final solution
Answer:
10⁶
Explanation:
A 1:100 serial dilution is a dilution in which the concentration decreases 100 fold (i.e., in each dilution the concentration of the culture must be multiplied by 10⁻²). The question above indicates that a three-step 1:100 dilution was applied, which means >> 10⁻² x 10⁻² x 10⁻² = 10⁻⁶. Moreover, the dilution factor can be calculated by dividing the volume of the diluted solution by the volume of the concentrated solution. The dilution factor is the inverse of dilution, thereby in this case this value is equal to 10⁶ (dilution = 10⁻⁶ >> dilution factor = 10⁶).

describe the role of enzymes in seeds germination
Answer:
Enzymes such as amylase ,protease and lipase are liable for solubilizing spare food materials in form of starch, protein and lipids correspondingly
in seed and deliver energy and other fundamentals food materials to germinating embryo.
The seed proteins are catalyzed by protease enzyme and break it into amino acid and peptides that a e transferred to growing embryo.
The amino acids obtained from metabolism of the proteins are further used in biosynthesis of enzymes,hormones,proteins, pyrimidines and Purine bases.
The starch is catalyzed by enzyme amylase that provides the food materials for growth and development of embryo . Similarly lipase are enzymes that are responsible for metabolism of the triacylglycerols into glycerols and fatty acids.This is also the source of energy for growing embryo

You are running a genetics experiment. Which of the following will help you obtain the copies of the gene you need?
A. Ribosome
B. Mesosome
C. Plasmid
D. Nucleus
Answer:
D
Explanation:
i think this is the answer because the nucleus contains threads of DNA called chromosomes.which can help in a genetic experiment.
I hope this helps
In the given context, Nucleus would help in obtaining the copies of the gene.
The nucleus controls and regulates the activities of the cell and carries the genes, structures that contain the hereditary information.
What is Nucleus?In cell biology, the nucleus is a membrane-bound organelle found in eukaryotic cells.
The nucleus was discovered by Robert Brown in 1831.
Nuclear DNA is a multiple long linear molecules in a complex with a large variety of proteins, such as histones, to form chromosomes. The genes within these chromosomes are structured in such a way to promote cell function.
The nucleus maintains the integrity of genes and controls the activities of the cell by regulating gene expression and thus control the center of the cell.
The main function of the cell nucleus is to control gene expression and mediate the replication of DNA during the cell cycle.
Nucleus houses an organism’s genetic code, which determines the amino acid sequence of proteins critical for day-to-day function, it primarily serves as the information center of the cell has been found that replication happens in a localized way in the cell nucleus.
What is Ribosomes?A ribosome is a complex molecular machine found inside the living cells that produce proteins from amino acids during protein synthesis or translation. The process of protein synthesis is a primary function, which is performed by all living cells.
Ribosomes are specialized cell organelles and are found in both prokaryotic and eukaryotic cells. Every living cell requires ribosomes for the production of proteins.
This cell organelle also functions by binding to a messenger ribonucleic acid (mRNA) and decoding the information carried by the nucleotide sequence of the mRNA.
They transfer RNAs (tRNAs) comprising amino acids and enter into the ribosome at the acceptor site. Once it gets bound up, it adds amino acid to the growing protein chain on tRNA.
What is Mesosome?Mesosome is formed by an extension of the plasma membrane into the cell wall. These extensions are usually in the form of vesicles, tubules, and lamellae.
The main use of mesosomes are:
- Synthesis of a cell wall.
- DNA replication.
- Distribution of daughter cells, respiration, secretions, etc.
What is Plastid?Plastids are double-membrane organelles which are found in the cells of plants and algae.
Plastids are responsible for manufacturing and storing of food. These often contain pigments used in photosynthesis and different types of pigments that can change the color of the cell.
Different types of plastids with their specialized functions are:
- Chloroplasts
- Chromoplasts
- Gerontoplasts
- Leucoplasts
