andre [41]2 years ago

Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption. They also contain lots of mitochondria , which release energy from glucose during respiration in order to provide the energy needed for active transport.

mylen [45]

The correct answer is: Individuals that produce chemical compounds are better protected from herbivores and are able to produce more young than individuals that do not produce the compounds.

Natural selection acts on variations-differences in phenotype that exist among individuals. If a certain trait contribute more to survival and reproduction (individuals with that variant survive more than individuals with other variant), natural selection will favor that trait. In this case, production of chemical compounds is favored over non-producing trait.

Describe the changes that a broken bone undergoes as it is healing.
Alex_Xolod [135]
<span>When a bone breaks your body immediately begins working to heal it. Within the first hours of a fracture a blood clot forms around the break and special cells call phagocytes begin cleaning germs from the bone fragments. Then, a soft callus composed of collagen is created around the break. Next, a hard callus forms as osteoblast cells work to create new bone to aid in the reconstruction process. After all is said and done the bone is remodeled by cells called osteoclasts. The bone will be completely rebuilt in 3-9 years.</span>

Rom4ik [11]

Male cones grow near the<u> lower region</u> of the plant, while female cones are located near the<u> top of the tree.</u>

Sexual Reproduction in Gymnosperms :

The lifecycle of a gymnosperm is also characterized by the alternation of generations, just as the lifecycle of an angiosperm. In conifers, such as pines, the sporophyte is the part of the plant that is green and leafy, and the gametophytes, in both male and female, are found in the cones. Female cones are distinguishable from male cones by their bigger size and their location closer to the crown of the tree. Male cones, on the other hand, are significantly smaller and can be found closer to the base of the tree. Because the pollen is dispersed and carried by the wind, it is impossible for a gymnosperm to self-pollinate due to the configuration of the plant.
