The individual organisms that frame a population are additional or less equally spaced, spread every which way with no predictable pattern, or clustered in teams. These are called the uniform, random, and clumped dispersion patterns. Uniform refers to the evenly distributed population, random means random spacing and clumped shows the distribution in clusters.
Food supply and resources are directly proportional to a particular distribution pattern. Random distribution occurs when several pollen grains of some flowers were carried by wind or bees. These flowers will then bloom where they were scattered.
hope this um ... helps hehe ........
Answer:
Anterior end
Explanation:
You have a pretty good shot at guessing this, because the earthworm has very little going on at the posterior end except the anus. And you probably saw this in lab, too.
I've attached a picture of the earthworm anatomy. Worms can't smell in the strictest sense, but they can use their receptors as kind of a combo smell-taste thing, and those are located in the anterior end.
Answer:
of diffusion
Explanation:
Molecules move down a concentration gradient without the need to use energy. This means they move from a high concentration to a low concentration. This occurs across a semi-permeable membrane, like the cell membrane, by simple diffusion.
The commence is off base with regards to the enthusiasm for creating fake blood. The intrigue is on the grounds that the timeframe of realistic usability of put away blood is extremely constrained. The other intrigue is concerning transfusion responses related with red platelet antigens that can bring about lethal responses and cause delays in finding good blood that hazard understanding lives. At present the rate of securing HIV disease through blood transfusions has been computed to associate with one case for every a million or two million transfusions. That viewpoint has been tackled with respect to testing however alternate issues still remain and they persuade the proceeded with look for simulated blood. Other developing infections like Zika and other obscure infections additionally makes a requirement for such research.
Answer:
A 22 to 25 amino acid sequence present in the central section of the protein, which gives rise to an alpha helix in the membrane is known as the stop-transfer anchor sequence. The sequence plays an essential function in targeting the protein towards the plasma membrane. On the other hand, it also ceases targeting of the protein towards the endoplasmic reticulum, which was started by the signal peptide.
Thus, the process of translation of the remaining of the protein occurs within the cytosol due to the tethering of the transmembrane domain. In the stop-transfer anchor sequence, the hydrophobic amino acids present are isoleucine and valine. After mutation, these amino acids get converted into arginine and lysine, thus, hydrophilic amino acids replace hydrophobic amino acids in the sequence.
Due to this, the transmembrane domain cannot be targeted towards an integral part of the plasma membrane by the short transfer anchor sequence, and therefore, now the translocation of the protein will take place towards the endoplasmic reticulum as initiated by the signal peptide at the beginning.
