Answer:
A. the two genes on chromosome 1 are more than 50 mu apart.
Explanation:
Two or more genes present on the same chromosomes are the linked genes. Linked genes do not assort independently and do not exhibit crossing over. Therefore, the linkage of genes results in deviations from Mendel's law of independent assortment. However, if the linked genes are present far from each other on the same chromosome, they may exhibit crossing over.
The greater the distance between the linked genes, the higher are the chances of crossing over. Crossing over of linked genes would result in some of the progeny to have the new gene combinations as it occurs during an independent assortment of two genes. Therefore, Mendel observed an independent assortment of two genes present together on chromosome 1 since they were present far apart from each other (more than 50 mu apart).
Answer: Add a different diet and maybe add an animal. If you put a bigger water bowl than the cage will become humid. If you change things about the terrain, its a desert so watering more plants and planting trees will make the ground more fertile to other plants. If you continue to take care of the plants until they are able to grow and reproduce. After enough time, where used to be a desert there will be a forest.
Answer:
Basophils of the blood help to get defensive leukocytes to the site quickly by releasing an anticoagulant called ___heparin_______ and a vasodilator called _____histamine_____
Explanation:
Basophils are a type of white blood cell containing specific granules that release histamine (vasodilator) and heparin (a substance with anticoagulant action) and azurophilic granules that contain lysosomes. They are important in allergic and anaphylactic processes.
The concentration of salt in water affects the rate of osmosis because it will determine how much water should be transported or excreted or to be taken in. The cellular process is keen to the salt concentration of its system thus making sure to maintain balance between the salt concentration the right amount of water must also be in its area of release for any expected occurences.
Osmosis then is the movement of water particles from which has water and from which has not and to provide it with the sufficient H2O.
