Homeostasis is an example of which of the following characteristics of life? a. organization b. metabolism c. responsiveness d. growth Define the role of the endocrine system in homeostasis using two examples. Describe how the cardiovascular system effectively works with all other body systems to ...
To gain insight into the molecular and genetic mechanisms underlying the sexual component of nervous system development, we asked how sexual identity, neuronal identity, and developmental stage intersect to drive gene expression in a model organism. We addressed this question using the nematodeCaenorhabdi...
elegans offers a unique opportunity to track how sex-specific characteristics emerge during neuronal development. C. elegans is an androdioecious nematode, with hermaphrodites (XX) and males (XO). Males are rare (0.01%) in the standard lab strain, and no obvious morphological or molecular ...
First, I investigate whether developmental noise is part of the explanation of the physical characteristics of individual organisms (i.e., the phenotypic outcome of development). Then, I try to assess whether or not heterogeneity due to stochastic events in development can be explained by a ...
radiata’s CI in SC I + III2 exhibited non-canonical characteristics in terms of its large-scale structure, its catalytic loops and its behaviour in the standard A/D assay. Discussion Here we present the cryoEM structure of active SC I + III2 purified from V. radiata mitochondria...
We believe that by investigating the patterns of expression variation across species and tissues specifically for each gene, we can provide a more meaningful answer to the question of whether the biology of an organism can be extrapolated to another. Indeed, the behavior of genes whose expression ...
What is an enzyme reaction? What are the characteristics of enzymes? (a) What are enzymes? (b) What are they for? Name and describe any two sources of saliva and salivary amylase for food digestion. Which of the following works at a pH of 2? A. Amylase. b. Pepsin. c. Lipase. d...
and 3 × 2n-1C for the endoreduplicated endosperm derived from triploid progenitor cells). Polysomaty is particularly common in higher plants [2]; for some species, such asA. thaliana, it is encountered throughout the mature tissues of the organism [3], while in others it is restricted to...
The freshwater planarianSchmidtea mediterranea, an important model organism for studies of regeneration22,23, exists as asexual and sexual reproductive strains. The sexual strain is distributed mostly in Tunisia and on the islands of Sardinia, Corsica and Sicily1. The sexual strain is a simultaneous ...
