Hi There!
Why is chemistry important in the study of biology?
Biology overlaps with chemistry in studying the structure and functions of activities at the molecular level. The principles of chemistry are useful in cell biology because all living cells consist of chemicals and various chemical processes take place in many living organisms!Biological organisms have chemical compositions. Carbon is found in all living organisms.
In a cell, protein synthesis is the primaryfunction of (1) ribosomes (3) chloroplasts (2) mitochondria (4) vacuoles
Answers
The correct answer is 1. Ribosomes. Ribosomes translate the codes andsynthesize proteins. Chloroplasts are connected to photosynthesis inplants because they contain chlorophyll, while mitochondria is thepowerhouse of the cell. Vacuoles are something like storage houses fornutrients and waste in a plant for excess food, as well as protectingthe plant from waste.
Where in an embryo are the instructions located for how to build organs
Answers
All the instructions are encoded in the DNA within the nucleus. We don't fully understand how the zygote, with the same genetic material as our adult cells, instructs the newly developing embryo to form tissues and organs, but it is all in the DNA.
It's cell differentiation signals produced by nucleus of cells. In an embryo, there are unspecialized pluripotent embryonic stem cells that rely on cell signals to differentiate into organs, even before the embryo is formed, in the blastocyst stage, there are 2 layers of cells, the inner cell mass is destined to form internal organs, and the outer ball of cells forms skin cells, intestines etc
What is homeostasis?
Answers
The ability for an organism to be able to regulate its own body temperature from the outside world.
Homeostasis is the tendency of a living organism to maintain its body temperature according to conditions or environment.
Choose the correct answer. -lactose is Glcα1-4Glc -maltose is Glcα1-4Glc -sucrose is Glcα1-2Glc -cellobiose is Galβ1-4Glc
Answers
The answer is lactose is Glcα1-4Glc.
Lactose is a disaccharide sugar derived from galactose (Glca) and glucose (Glc) which form a β-1-4 glycosidic linkage (Glca1-4Glc).
All living organisms are made from different combinations of only ___________ amino acids. 15 20 25 30 double helix bi-helix twisted strand triple helix
Answers
All living organisms are made of only 20 different aminoacids- this is the correct answer! This means that the genetic code only codes for those 20 aminoacids (for example Glutamine and Lysine). The 20 aminoacids that can form proteins are also called Proteinogenic amino acids.
yep its b have a nice day :)
