Answer: Affiliative behavior
Explanation:
Affiliative behavior is the behavior in which social interaction is seen between two animals through cohesion, meeting, hugging, involvement with each other, playful acts etc. They try to display emotional and social bond between them.
According to the question, chimpanzees displaying embracing behavior , ticking and little wresting shows that they have social and emotional link with each other.
Thus, they have affiliative behavior rather than aggressive and anger-based behavior.
Answer:
In stem cell transplants, stem cells replace cells damaged by chemotherapy or disease or serve as a way for the donor's immune system to fight some types of cancer and blood-related diseases, such as leukemia, lymphoma, neuroblastoma and multiple myeloma. These transplants use adult stem cells or umbilical cord blood.Explanation:
Answer: b. They are composed of molecules that contain carbon-carbon bonds.
c. They undergo chemical reactions to use energy they acquire from the environment.
Living things includes all the organisms that display features which make them distinct from non-living organisms. The living organisms have an organized structure, they are composed of cells, they require energy to survive or sustain existence, they are able to reproduce and they exhibit ability to grow.
They are composed of molecules that contain carbon-carbon bonds: Carbon is the main component present in all living things. They make up the organic biomass of these living organisms.
They undergo chemical reactions to use energy they acquire from the environment: The plants traps sunlight energy and converts it into food and lastly into chemical energy in the form of ATP. This ATP is used as a energy reservoir for metabolic processes occurring in the plants. Therefore, energy is generated after chemical reactions.
Answer:
24%
Explanation:
The given genetic trait is homozygous recessive and the frequency of homozygous recessive genotypes in the population is 2%.
Therefore, frequency of homozygous recessive genotypes (q2) = 2% = 0.02
Frequency of homozygous recessive allele (q) = square root of 0.02 = 0.141
Since p+q =1 (here, p = frequency of dominant allele).
So, p= 1-q = 1-0.141 = 0.859
The frequency of heterozygous carrier genotypes in the population = 2pq = 2 x 0.141 x 0.859 = 0.24 or 24%
