Answer:
C) The increased ability of an individual plant (above baseline) to withstand further drought after it has received a heat shock, which causes the expression of specific proteins that enable more efficient use of water
Explanation:
In biology, adaptations refer to the characteristics of organisms that allow them to survive and reproduce better in their environment than if they did not possess them. Many of these adaptations are very easy to recognize, such as bird beaks that are highly specific to the food they eat, for example. It is now accepted by science that only natural selection can consistently produce adaptations, although it is important to note that it is not the only evolutionary mechanism. Natural selection, whose idea is mainly attributed to Charles Darwin, acts directly on the phenotypic characteristics of individuals in a population, favoring those who are most likely to survive and reproduce in a given environment over those who are less adapted.
Based on this, we can conclude that adaptation is a biological process that occurs without human manipulation. Thus, we can conclude that among the options given in the above question, the letter C does not represent an example of adaptation. This is because the letter C, shows a plant that showed characteristics favorable to its survival in an inhospitable environment, after human intervention, which, through a thermal shock, caused the expression of specific proteins for that characteristic.
Answer:
Constant variables
Explanation:
Elaina's investigation lacked the critical ingredient of constant variables which are important components of every scientific investigation. In every research, there are 3 important variables, namely:
1. Dependent variables: the actual variable to be measured during the course of investigations and whose values are dependent on another variable (independent variable) supplied by the investigators.
2. Independent variable: one of the variables that are supplied by investigators whose values are often manipulated to see the kind of changes it will cause to the dependent variable.
3. Constant variables: other variables that are neither independent nor dependent but constant for all the various experimental groups in investigations.
Glands are classified as ENDOCRINE or EXOCRINE depending on their route of secretion. ENDOCRINE GLANDS secrete their products, called hormones, directly into the blood. ... Their products are NOT released into the blood. Exocrine glands are classified on the basis of the number of cells making up the glands.
Answer:
Bacteria reproduce by binary fission. In this process the bacterium, which is a single cell, divides into two identical daughter cells. Binary fission begins when the DNA of the bacterium divides into two (replicates).
Explanation:
Answer:
Research has shown that sea otters are doing their part by indirectly reducing the carbon dioxide (CO2) concentration in the atmosphere. It starts with vast areas of kelp forests that, through photosynthesis, absorb atmospheric CO2 and release oxygen into the air.
