Which organ is responsible for dehydration and compaction of indigestible materials?

Biology
1 answer:
My name is Ann [436]3 years ago
3 0

Answer:

Large intestine

Explanation:

After the completion of digestion process in the small intestine, the indigestible residual materials are passed to the large intestine.

The large intestine serves three primary functions -

  1. Absorption of water and electrolytes
  2. Production and absorption of vitamins
  3. Formation and propelling of feces accomplishing their removal through the rectum.

When water gets absorbed, the indigestible materials get dehydrated and during feces formation they are compacted and then eliminated through the rectum.

In the heart, the valves are located between atria and ventricles and between ventricles and arteries (option D).

<h3>What are valves in the heart?</h3>

Valves are membranous partitions which permit the passage of the contents of a vessel or cavity in one direction, but stop or control the flow in the opposite direction.

Valves in the heart enforce a one-way blood flow through the heart and separate atria from ventricles, and ventricles from the large arteries that leave them.

The four valves in the heart and their location is as follows:

  1. tricuspid valve: located between the right atrium and the right ventricle
  2. pulmonary valve: located between the right ventricle and the pulmonary artery
  3. mitral valve: located between the left atrium and the left ventricle
  4. aortic valve: located between the left ventricle and the aorta.

The valves between the atria and ventricles are called atrioventricular valves or cuspid valves while those at the bases of the large vessels leaving the ventricles are called semilunar valves.

Therefore, it can be said that the valves of the heart are located between atria and ventricles and between ventricles and arteries.

IrinaK [193]

Answer:

(a) E-cadherin growth suppressor genetic factor are significantly active space of analysis in growth and tumorigenesis. The calcium reliant connections between E-cadherin particles are essential for the creation and conservation of supporter connections in parts of animal tissue cell-cell interaction.

CAMs admire the cadherin glycoproteins ordinarily perform because the adhesive that grips cells along and performance as necessary intermediaries of cell to cell connections. E-cadherins, on the superficial of all animal tissue cells, are joined to the simple protein bodily structure complete connections with catenin’s within the protoplasm

(b) scleroprotein synthesis is exclusive assumed its closing gathering phase. justify this declaration. The last part originates from the establishment of precise amino acids admire Glycine, aminoalkanoic acid and Hydroxproline. scleroprotein additionally has 2 unusual spinoff amino acids that don't seem to be straight introduced throughout translation.

Collagen consists of three handcuffs. The manacles are looped along to create a multiple helix. the method of scleroprotein synthesis happens principally within the cells of fibroblasts that are specialised cells with the most perform of manufacturing collagen and stroma. scleroprotein mixture happens each intracellularly and extracellularly.

 

c. Laminin could be a substance of integrin’s receptors. it's AN RGD theme that dilemmas to RGD compulsory sphere on receptor. So as to investigate whether or not the somatic cell composition is because of compulsory of laminin to integrin’s, ab initio it's to be verified, that integrin’s are profusely articulated on the somatic cell semipermeable membrane. This may be achieved mistreatment technique examination via antibodies or by template RNA appearance by RT-PCR.

The appearance of those integrin’s may be inhibited mistreatment RNAi by siRNA method. The siRNA can destroy the template RNA for the integrin because it contains a balancing arrangement to the mRNA. The damage of template RNA can source decreased macromolecule appearance. The cells will then be coated on the 3 glazed plates makeshift, laminin. If the cells provide spherical cells, formerly the somatic cell composition are going to be because of integrin-laminin collaboration. The cells may be gathered and testes for somatic cell indicators that designated distinction to neuronal composition. If no diversity indicators are specificed in laminin covered plates with distorted cells as likened to the management cells that rapid integrin’s, then it's laminin integrin communication that's chargeable for the somatic cell composition see, simple protein thread designs can even be deliberate on top of things and distorted cells produce on laminin covered plates by technique.

Another technique which will be utilized is to pelt the philosophy plate with changed laminin macromolecule that absences the RGD themes. The somatic cell cell appearances will then be plated and refined on the management laminin and changed laminin missing RFD themes. If the somatic cell composition isn't ascertained, then it may be over that laminin-integrin connections are concerned in growth of the somatic cell composition.

(d) Glycosaminoglycans (GAGs) are necessary electronic warfare parts, as a result of they're extremely charged polymers that powerfully dilemma aquatic and ions, making state in electronic warfare areas, and since they dilemma and confiscate physiologically necessary proteins.

Proteoglycans facilitate control trails that management vegetative cell fate, and so represent a wonderful tool to control these trails. Although their position, there's a scarcity of knowledge linking glycosaminoglycan construction inside proteoglycans with vegetative cell variation.

Which of the following situations does diffusion not help, in our bodies?A. Oxygen entering the bloodstream.B. Food entering the
lubasha [3.4K]

Answer:

Glucose entering the intestines from the villus.This is by active transport.The latter is defined as the movement of molecules and  solutes from the region of lower concentration to the region of higher concentration against the concentration gradient.

Explanation:

All the above options depends on the diffusion gradients from one  higher region to another.e.g oxygen passing from high concentration from outside to lower concentration in blood stream,like wise Co2 from higher concentration from inside to outside,with passive diffusion lipids and water enter the small intestine(note amino acid and glucose,and fructose are different).

Active transport( through sodium dependent transporter) transports glucose to the intestine  from the villus.This is movements against concentration gradient because,glucose molecule are concentrated in intestine,and needed by the cells, in the body.Therefore they must be transported as a fast rate inn the blood .

However the absorption by the villi is very slow,therefore active transport is needed to move these against the concentration gradient into the intestine.And finally the blood.

If this were to be moved by  passive diffusion,the high concentration in the intestine will force this back into the villi

Therefore extra energy is needed by active transport for the glucose molecules to enter the intestine from the villus.
