Answer:
True
Explanation:
Reproduction is one of the essential characteristics of all living beings. However, if they reproduce to their full capability, the number of offspring would be higher than the available resource. Due to this reason there is always shortage of resources and hence competition arises among the species.
The fit species survive among all the competing species while the remaining weak species die. As Darwin also said that species have the ability to reproduce uncontrollably therefore, competition among the species for survival is a mode of population regulation
Hence, the given statement is true
Answer:
The answer to your question is: C
Explanation:
A.) Plants digest sugars to make energy. This option is incorrect, the process in which plants digest sugars to make energy is called cellular respiration.
B.) Plants use oxygen and glucose to make carbon dioxide. This option is incorrect, photosynthesis doesn't make carbon dioxide, it use it to make sugar.
C.) Plants use sunlight and carbon dioxide to make sugars. This option is correct, photosynthesis is a process that use carbon dioxide to make sugars.
D.) Plants use sunlight to make chlorophyll and chloroplasts. This option is incorrect, plants use sunlight in the photosynthesis process to make sugars, not to make chlorophyll and chloroplasts.
The answer is D. Food Threshold is the amount of food capable on feeding the organisms.
Membrane proteins can be classified into two broad categories—integral (intrinsic) and peripheral (extrinsic)—based on the nature of the membrane-protein interactions (see Figure 3-32). Most biomembranes contain both types of membrane proteins.
