Answer:
Middle adulthood, or middle age, is the time of life between ages 40 and 65. During this time, people experience many physical changes that signal that the person is aging, including gray hair and hair loss, wrinkles and age spots, vision and hearing loss, and weight gain, commonly called the middle age spread
Explanation:
I believe the answer is Research.
Answer:
a. Multiple gene duplication events have led to the production of a paralogous multigene family.
Explanation:
A globin gene family consists of several clusters of related genes formed by duplication of an ancestral gene. The different variants of venom proteins coded by closely related genes can reply this ancestral gene, forming this way a globin gene family in Cone snails.
The standard plate count (SPC) method involves diluting 1.0m of bacterial culture into a series of water blanks, and then taking a sample from the water blanks to add to empty petri plates which will be filled with melted agar.
The standard plate count is a method used in microbiology, which is used to gain an insight to estimate the density of bacterial population which is present in a bacterial culture broth. This is done by plating a small concentration of the culture in a petri-dish and then counting the colonies which form in the petri-plate. This method is used mostly in the food industry, to find the density of mesophilic bacteria in food. This method is extremely essential to determine the primary source of the bacterial contaminant.

A baker has created a new strain of yeast which contains no cytochrome c gene and no cytochrome c protein. this will affect what the yeast strain can do to obtain energy. what will this yeast strain do more of compared to a normal strain
Will this new strain of yeast obtain more or less free energy from glucose in its growing medium?
Answer: Less because cytochrome c is key to the electron transport chain.
Explanation:
The Cytochrome c is an essential component of the electron transport chain. Without this there will be no oxidation and reduction of iron atom will take place which could convert the ferrous ions to ferric ions. Thus the entire process of electron transport chain and energy production in the form of ATP will be compromised. So, there will be no production of energy in the anaerobic fermentation by yeast.
