Answer:
in sexual reproduction we get genes from both our parents and we have a combination of them...that leads to genetic diversity...more diversity means more chances to survive different environment conditions.... in asexual reproduction.. offsprings are identical.if environment conditions are rough...all of them won't stand a chance...and also....in sexual reproduction genetic variation can lead to evolutionary advancements
Enzymes are regulated by more than the binding of small molecules. A second method that is used all the time by eucaryotic cells to regulate a protein's function is the covalent addition of a phosphate group to one of its amino acid side chains. These phosphorylation events can affect the protein in two important ways.
Answer:
The correct answer is -Sponges lack true tissue but have morevariation in cell type than animas in oter phylum.
Explanation:
Sponges are belong under phylum porifera which have diverse form encrusting sheets to volcano shaped mounds.
The tubes that contain in their body are differ in size from millimeter upto one meter.
The poriferans contain canal system and with help of this, they pump water which enters through a specialed pores called ostia that flows through canal called spongocoel and finally the water exits from their body through oscula.
The sponges show complex organization as their body contain single tube with 2 cell layer thick.
Ascon,leucon,sycons are the level of complexity.
The purpose of a quick body response is from your brain. Your brain has a nervous system that can tell you to do things that you should.
In this case, Pulling your hand away from a hot stove could be dangerous, so you nervous system quickly reacts to take your hand away from the stove.
Answer:
The structure labeled X in the diagram is a membrane protein.
Explanation:
Membrane proteins are integral parts of the cell membrane that enable the transfer of ions like sodium, potassium and chlorine and small molecules like glucose through the lipid bilayer. They differ from other types of cell proteins by their structure. As you can see on the diagram, hey form channels that enable specific ions or molecules to pass to the other side of the membrane.
