Answer:
<em>True: </em><u>b) Tissue is a group of specialized cells that work together for a common function and form organs.</u>
Explanation:
Cells are the smallest units of life, they may be either unicellular or multicellular. Unicellular organs have a single cell capable of carrying out all of the functions necessary for its survival. Multicellular organisms are more complex, and require the work of multiple different cell types.
Their cells become differentiated- where they undergo certain processes to become specialized, and gain maturity. Groups of specialized cell types form tissue; these each have varying functions over time. Organs consist of two or more tissue types that are specifically organized to carry out a function.
Answer:
the chicks and mouse would be losely conected because they have more of the same gentic material and fish and humans would havwe the same since they kind act like the same because The recent advances in developmental biology described have established the central importance of a small number of highly conserved signal transduction pathways that mediate cell interactions crucial for animal physiology, reproduction, and development. It seems likely that many developmental toxicants might affect development by acting on those pathways. Application of the methods that have been so successful in elucidating them should now allow scientists to investigate that possibility and to determine the mechanisms by which developmental toxicants act. This chapter reviews the experimental approaches primarily responsible for the recent advances in knowledge about animal development and discusses how those approaches might be applied to developmental toxicology. Chapter 8 discusses how those approaches might lead to improved qualitative and quantitative risk assessment.
The corresponding sequence in the RNA transcript is 5'-UACGACUG-3' . One of the differences between DNA and RNA is the fact that the RNA contains the base uracil instead of thyamine. The base pairing occurs between A and T, and G and C. DNA undergoes the process of transcription in the nucleus to generate RNA, which then undergoes translation (for mRNA) in the cytoplasm to yield proteins.
Answer:
( please like and hope it helps)
A) Elephas-2 has 13 sequence differences from the reference animal, and this is the greatest number of animals in the table.
B) From left to right, the order at the tips of the cladogram is: Dugong , Elephas , Loxodonta , Mammathus.
(Loxodonta and Mammuthus can also be reversed)
C) The molecular data, such as that for are widely conserved protein such as cytochrome b , show conserved similarities between organisms such as to dugongs and proboscideans and can be used to support the existence of this relationship.
D) The animals that are related ones had a common assister with certain genetic characteristics. Adaptation to different habitats leads to diversification of morphology but does not change evolutionary relationships.
