I believe the correct response is A. The population of secondary consumers would decrease, as now these organisms can't obtain energy through the food they consume which is the primary consumers as there is none and thus the population in higher tropic level dependent on them would decrease. This is the secondary consumer.
Answer: the answer is option A. 5 → 1 → 6 → 3 → 2 → 4
Explanation: the events that describe progress of a protein that will be secreted from cell are as follows; Protein synthesis begins in the cytosol, SRP binds to the growing polypeptide chain and to the ribosome, Translation pauses, SRP binds to its receptor, Translation resumes and finally - The signal sequence is cleaved. All these formed the sequence 5 → 1 → 6 → 3 → 2 → 4
<span>Anton van Leeuwenhoek learned to grind lenses ( 1668) and develop simple microscopes.
</span>
Leeuwenhoek heated the middle of a small soda glass rod , over a flame. On pulling apart the two ends, the glass rod elongated into thin whiskers .
Heating the end of this whisker resulted in a tiny high quality glass sphere. These glass spheres then became the lens of his microscope, with the smallest sphere providing the greatest magnification.
Leeuwenhoek's designs were very basic. The body of the microscope was a single lens mounted in a tiny hole on a brass plate. The specimen was then mounted on a sharp point that sticks up in front of the lens. It's position and focus could be adjusted by turning the two screws.
The entire instrument was about 3 to 4 inches long and had to be held up close to the eye, requiring good lighting and great patience to use.
C. they are always heritable. b. they are inly heritable in gametes
Answer:
Natural selection will favor red deer that produce a dozen or more offspring that survive for at least a year.
Explanation:
Natural selection results in adaptation, which means the increase of the aptitude phenotype. Aptitude is the contribution of each genotype to the next generation.
Natural selection is the result between the individual phenotype and the environment that determines the destiny of genes. It is the differential capability of individuals to leave offspring.
Aptitude (or fitness) is the phenotype that results in the survival, fertility, and capability of having a mate. It is a way of measuring the individual ability to leave fertile offspring. Aptitude must be significant to the natural selection act in its favor.
Natural selection, eventually, will favor red deer that produce a dozen or more offspring that survive for at least a year. These animals have more chances of leaving fertile descendants that will be able to grow, develop, survive, and reproduce. They have a higher aptitude than those individuals that only have four fawns during their lifetimes. These animals have fewer probabilities of leaving survival descendants able to reproduce.
