Which best explains enzyme specificity?
O An enzyme is able to react with many different substrates
O An enzyme works best at certain pH
O An enzyme works best at a certain temperature
O An enzyme is only able to react with one substrate
The correct placement of side-chain functional groups that interact with the charged groups of the new substrate is necessary to change an enzyme's selectivity. In order for the functional groups to be positioned correctly, this necessitates sequence alterations that not only add the new functional groups but also modify the structure of the protein backbone. We present a computational design approach for the targeted modification of loops close to the active site to introduce unique enzyme-substrate interactions. The approach can restore native loop lengths and, frequently, native loop conformations, according to benchmark studies on 8 native protein-ligand complexes. Next, we redesign a crucial loop in human guanine deaminase using the technique to ensure that an important side-chain contact is made with the substrate ammelide.

all chemical processes which take place in living cells ??
Biochemical reactions are chemical processes that occur within living organisms.
Chemical processes known as "biochemical reactions" happen within the cells of living beings. The study of biochemistry shows that understanding both chemistry and biology is necessary to comprehend how cells function in living things at the level of the organism. Metabolism is the collective term for all biological processes that occur within an organism. Both exothermic and endothermic reactions are a part of it.
Catabolic reactions are exothermic processes that occur within living things. These processes disassemble molecules into smaller parts while also releasing energy. The breakdown of glucose is an illustration of a catabolic reaction, which releases the energy required by cells for their vital functions. Anabolic reactions are endothermic processes that occur within living things. These processes combine tiny molecules into larger ones.
A biochemical reaction is the transformation of 1 molecule to a one-of-a-kind molecule inside a mobile. Biochemical reactions are mediated through enzymes, which might be biological catalysts which could alter the rate and specificity of chemical reactions internal cells.
Photosynthesis, gluconeogenesis (synthesis of glucose from non-carbohydrate resources, specifically used by the brain), protein biosynthesis, fatty acid synthesis, glycolysis, Krebs cycle, urea cycle, glycogenolysis are some common examples of biochemical reactions.

A) explosive with a pyroclastic flow B) non-explosive with a pyroclastic flow C) explosive with pyroclastic and lava flows D) non-explosive with a lava flow
PLEASE HELP GIVING BRAINLIEST TO FIRST CORRECT ANSWER
A cinder cone volcano easily erodes because it is made of ash and other volcanic debris. This indicates that its eruption is primarily explosive with a pyroclastic flow.
Volcanoes with cinder cones are the most basic. They are made of lava chunks and blobs that were ejected from a single vent.
A single vent is surrounded by a conical formation of ash, tephra, and solidified lava called a cinder cone. After being ejected into the air from the vent, volcanic debris breaks apart and falls to the ground, forming the cone. As the ash and lava cool and solidify, they form a cone around the vent.
The height of a cinder cone can range from 10 to hundreds of meters, and its summit frequently features a bowl-shaped crater. They differ from spatter cones, which are made of agglomerated volcanic bombs, in that they are made of loose pyroclastic material (cinder or scoria) and hence eruption is primarily explosive with a pyroclastic flow.

Ionic bonds, also known as electrovalent bonds, are a type of linkage created in a chemical molecule by the electrostatic attraction of ions with opposing charges. When the valence (outermost) electrons of one atom are permanently transferred to another atom, a bond of this kind is created. If an atom gains electrons, it becomes a negatively charged ion (cation), while if it loses them, it becomes a positively charged ion (cation) (anion). Following is a quick discussion on ionic bonds. Ionic or electrovalent compounds are produced via ionic bonding, and the compounds generated between nonmetals and alkali and alkaline-earth metals serve as the best examples of this type of compound.

A. 0.4 kg B. 4 kg C. 40 kg D. 400 kg
GRESA method stands for given, required, equation, solution and answer.
We are required to solve the question according to the GRESA method. However, the question has multiple sub questions and hence we will solve each one of them separately.
Question 1:
Given:
Net force of 200N
initial velocity is 0 m/s
final velocity is 40 m/s
time is given to be 10 s
Required:
We are required to find the mass of the cart.
Equation:
By using Newton's second law of motion,
F= m x (v-u)/t
Solution:
By putting all the values, we get:
200N = m x ( 40 -0 ) / 10
m = 200 /4 = 50kg
Answer:
The weight of the cart is 50kg.
Hence option (c) 50kg is correct
QUESTION 2:
Given:
mass of ball = 0.4 kg
force of hitting = 16N
Required:
We are required to find the acceleration of the ball after hitting
Equation:
Using Newton's law of motion,
F = m x a
Solution:
By putting all the values, we get:
16 = 0.4 x a
a =16/0.4 = 40 m/s^2
Answer:
Hence option (B) 40 m/s^2 is the correct answer
QUESTION 3:
Given:
mass of papaya =3.5kg
acceleration of papaya = 2.2 m/s^2
Required:
We are required to find the net force applied
Equation:
Using Newton's law of motion,
F = m x a
Solution:
By putting all the values we get:
F = 3.5 x 2.2
=7.7 N
Answer:
The external force applied is 7.7 N to the left
Question 4:
Given:
net force = 300N
acceleration = 0.750 m/s^2
Required:
We are required to find the mass of the crate
Equation:
By using Newton's second law of motion,
F= m x a
Solution:
By putting all the values, we get:
300 = m x 0.750
m = 300/0.750
= 400kg
Answer:
Hence the weight of crate is 400kg

What is the percent probability that the first child of this couple will have Huntington's disease?
probability: %
What is the percent probability that four of the seven children will have Huntington's disease?
probability: %
1. The percent probability that the first child of the couple will have Huntington's disease is 50%
2. The percent probability that four of the seven children will have Huntington's disease is 6.25%
Genetical probabilitiesThe disease is autosomal dominant. Only one dominant allele is needed for the disease to be manifested.
The husband is Hh and the wife is hh.

the arrows in the diagram stands for forces in earth,s crust pulling apart the two slabs of rock. this force is called
a.) tension
b.) elavation
c.) compression
d.) shearing
Answer:
I'm pretty sure it is c or a
Forces in earths crust pulling apart the two slabs of rock, this force is called Tension. Therefore, option (A) is correct.
Earth's crust tension pulls rock apart. At divergent plate borders, tectonic plates move apart. Faults form when tensional forces strain and thin rocks when plates separate. These faults can create rift valleys, mid-ocean ridges, and other geologic features.
Seafloor spreading and continental rifting are driven by tension. As plates separate, magma from the mantle rises to build new crust. New crust is formed at mid-ocean ridges. Tensional forces can also cause continental rifting and ocean development. Tension forms Earth's crust and moves tectonic plates. Therefore, option (A) is correct
