Answer:
Convection only occurs in liquids and gases. For example: Air and ocean
Answer:
Option D, TT
Explanation:
As per the given situation, the cross on tall plant will give only tall offspring.
Let us take the cases one by one
a) Tt or tt
Here genotype "tt" does not represent a tall pea plant and hence, this option is incorrect
b) Tt
This genotype will produce heterogyzous tall pea plant but when the cross will be done between two pea plants having genotype "Tt" , 50% of the offsprings will have "tt" genotype, thus they will not be tall. Hence this option is incorrect
c) tt
This genotype represent short pea plant, hence this option is incorrect
d) TT
This genotype represent homozygous tall pea plant and when a cross is carried out between two homozygous tall pea plants, all the offspring plant will be tall with genotype "TT". Hence, this option is correct.
Answer;
Evolutionary psychologists; behavioral psychologists
Evolutionary psychologists look at the genetic tendencies that we share as a species, whereas behavioral psychologists explore human genetic differences.
Explanation;
-Evolutionary psychology is a theoretical approach to psychology that attempts to explain useful mental and psychological traits such as memory, perception, or language,as the functional products of natural selection. Evolutionary psychology is focused on how evolution has shaped the mind and behavior.
-Behaviorism is concerned with how environmental factors affect observable behavior. The behaviorist approach proposes two main processes whereby people learn from their environment: namely classical conditioning and operand conditioning.
Bromothymol blue solution is an indicator that changes color in the presence of a weak acid or base. So release of carbon dioxide into water which turns into a weak acid. Therefore the cellular respiration is the driving the color change. ... both the release of gas and cellular respiration.
Answer:
Protists are unicellular eukaryotes which show both plant and animal characters and these are considered as a bridge between plants and animals.
Explanation:
Protists are single-celled life forms and are eukaryotic organisms. Some of the protists like euglena shows both plant and animal characteristics. Protists are important in the following aspects -
- These are a good source of food for many animals. For example phytoplankton is the major source of food for whales. Zooplanktons also serve a good source of food for many aquatic organisms. These organisms often serve as the foundation of the food chain.
- By doing photosynthesis they also used to be beneficial in the balance of ecosystem.
- Some protists are also used as biofuel.
- They often show symbiotic relations with other organisms.
