The structure and function of the lactase enzyme remain unchanged during the course of the reaction. After the bond is broken, the lactase enzyme is free to catalyze more reactions with other lactose molecules.

A decrease in GFR will cause __________.
lara [203]
<h2>GFR </h2>

Explanation:

A decrease in GFR will cause lower Na and Cl ion concentration in the distal tubule

  • GFR stands for Glomerular Filtration Rate
  • The rate at which kidneys filter blood is called the glomerular filtration rate
  • The main driving force for the filtering process, or outward pressure is the blood pressure as it enters the glomerulus which is counteracted to some extent by inward pressure due to the hydrostatic pressure of the fluid within the urinary space, and the pressure generated by the proteins left in the capillaries that tend to pull water back into the circulatory system (colloidal osmotic pressure)
  • The net filtration pressure is the outward pressure minus the inward pressure

Answer:

chewing gum

Explanation:

when chewing gum you'll likely think back to the last time you had gum. The trick is to study while chewing gum and, when you chew another piece of gum, you'll remember back to when you had it earlier along with the information that you remembered as you were chewing the gum.

Ralph has type B blood and his wife Rachel has type A blood. They are very shocked to hear that their baby has type O blood, and
Cerrena [4.2K]

Answer:

1. The parents genotypes could have been BO and AO

2. wire-hair

Explanation:

There are four possible blood types which are type A, B, AB, O. blood group is the classification of blood based on the presence or the absence of inherited antigenic substances on the surface of the red blood cells. They have hereditary basis and also rely on a series of alternative genes sometimes used in solving dispute of parental heritage. With the four possible blood groups, there are six possible genotypes and these are:

Blood type               possible genotypes

Type A                         AA, AO

Type B                         BB, BO

Type AB                           AB

Type O                              OO

Thus, for parents with blood type B and A to give birth to a child with blood type O, it means their genotype could have been both BO and AO  for them to be able to produce a child with OO. a cross between these two could give rise to OO.

Question 2

Wire hair is dominant (S) to smooth (s), thus wire hair could be in the homozygous (SS) and heterozygous form (Ss) and the smooth hair can only be expressed in the homozygous recessive form (ss).

thus, in a cross between homozygous wire haired and smooth haired, we will have:

homozygous wire haired            homozygous smooth haired

P gen              SS                x               ss

F1 gen.                                Ss

phenotype:                     wire haired
