If two homozygous plants with contrasting traits are crossed, the expected genotypes for the offspring will be heterozygous. The dominant trait would be expressed, but they'd be carriers for the recessive trait.

svetlana [45]

Answer:

Apply the principle of parsimony

Explanation:

A cladogram is used to show or illustrate hypothetical speciation and relationships between species. They are commonly used to classify animals.

The principle of parsimony argues that the simplest of competing explanations is most likely to be correct.  

In order to construct a cladogram that best reflects the evolutionary relationship of a group of species. Application of the principle of parsimony  will help in deciding which tree is most likely to have occurred based on the fewest character state changes.

Homeostatic regulation usually involves a(n) ________ that detects a particular stimulus, and a(n) ________ that responds to the
geniusboy [140]

Answer:

c) receptor; control center; effector.

Explanation:

Homeostasis maintains the internal body conditions almost constant. It includes specific cells that sense any deviations of internal or external conditions from the normal range. These cells are called receptors. The sensory information from the receptors is delivered to the control center. The central nervous system mainly serves as a control system wherein sensory information from the receptors is processed. The control center commands muscles and/or glands to perform desired responses to restore the homeostasis. Here, muscles and glands serve as effectors.

For example, thermoreceptors sense the rise of body temperature and the brain (control center) commands sweat glands (effectors) to produce sweat.

3. What adaptation of land plants helps it to control gas exchange with the atmosphere?
Alecsey [184]
3) C. Stomata, as I explained in my previous answer.

4) B. Nonvascular, low-hanging plants living in moist environs don't have to fight gravity nearly as much as tall ones do. So they needn't highly developed vessels to transport to their tips

5) B. Gravity, see above. The higher trees/plants grew, the further their apical structures were from ground water sources, so the lignin-supported, strong vascular tissue (phloem) allows the transport of water against gravity, using a capillary method (benefiting from the adhesive effect of water molecules).
