What is the function of Taq polymerase?
to add nucleotides to a DNA primer
to break the hydrogen bonds of DNA strands
to make more repeats of the STR sequence
to separate the sugars and phosphates in DNA
Answer:
to add nucleotides to a DNA primer
Explanation:
The Polymerase Chain Reaction (PCR) is a technique widely used in molecular biology in order to amplify small segments of DNA (100 to 1000 bases). PCR uses a thermostable DNA Taq polymerase that adds nucleotides to the DNA template at the position specified by short single-stranded DNA primers that bind to this template by complementary base pairing during the annealing phase of the PCR cycle. Subsequently, the DNA polymerase adds deoxynucleotide triphosphates (dNTPs) to the opposite DNA strand, this phase of the PCR cycle is known as the elongation phase. Finally, the resulting double-stranded DNA fragment is separated by heat during the denaturation step and this 3-step PCR cycle is repeated many times to amplify the target DNA region.

how is your heart like a water bottle that has to be squeezed for the water to come out
Answer:
The water bottle sign or configuration refers to the shape of the cardiac silhouette on erect frontal chest x-rays in patients who have a very large pericardial effusion. Typically the effusion has accumulated over many weeks to months (e.g. in patients with malignancy) and the pericardium has gradually stretched.
The heart is the pumping organ of the body it pumps the blood to the various parts of the body. The heart is made up of cardiac muscle and has 4 chambers, these chambers are as follows:-
AuricleVentricleAll these chambers of the heart receive the blood from the various part of the body and it pumps out the blood to the other parts.
The heart contracts and relax rhythmically to pump the blood from the heart, as we squeezed the fully filled water bottle, the water comes out.
In the same way, the heart works too, in which blood comes out from the heart when it contracts.

When a molecule other than substrate binds to the active site of an enzyme and
slows its activity
Definition
Answer:
Competitive inhibition
Explanation:
Competitive inhibition is a type of enzyme inhibition where one molecule inhibits the effect of another molecule (called the substrate) by competing with it for binding at the active site of the target enzyme, thereby preventing the substrate from binding. The active site refers to the specific region of an enzyme that binds with a particular substrate. This mechanism is well-known in pharmaceutics, where specific drugs are designed to show structural resemblance to a particular substrate, preventing its normal function.
Look at the reaction below.
H2SO4(aq) + Ca(OH)2(aq).
→ CaSO4(aq) + 2H2O(1)
Which substance is the base in the reaction?
2H20 (1)
H2SO4 (aq)
CaSO4 (aq)
Ca(OH)2 (aq)
Answer:
Ca(OH)2 (aq)
Explanation:
The balanced neutralization reaction i.e. a reaction between an acid and a base, in this question is given as follows:
H2SO4(aq) + Ca(OH)2(aq) → CaSO4(aq) + 2H2O(l)
According to Arrhenius in his definition of acid and base, a base is a substance that dissociates into hydroxide ions (OH-) when in an aqueous solution. In other words, a base increases the concentration of hydroxide ions when dissolved.
In this reaction, Ca(OH)2 releases the OH- (hydroxide ion) that combines with the hydrogen ion (H+) released by the acid, H2SO4, to form water (H2O). Hence, Ca(OH)2 (aq) is the BASE.
Answer:
Ca(OH)2 (aq)

Explanation:
Which makes a bigger difference: a 100 kg increase in the mass or a 100 meter/sec rise in velocity?
An increase in mass of 100 kg. No, it is not true that an object moves faster quickly the less mass it has, as your example demonstrates very clearly. Another illustration: a snail moves more slowly than a rocket but weighs much less. Thus option A is correct.
What mass makes a bigger difference compare to velocity?The heavier (denser) object will fall quicker if two identically sized but made of different materials objects are present. This is because both objects will experience the same drag and buoyancy forces, but the heavier object will experience a stronger gravitational pull.
The less an object accelerates when a certain force is applied, the more mass it has. For instance, the acceleration is halved for a given force when the mass of an object is twice.
Therefore, a 100 kg increase in the mass. No, as your example clearly shows, it is not true that an object travels more quickly the less mass it possesses. Another example: a snail travels slower than a rocket but is considerably lighter.

D. kingdom, order, phylum, family, class, genus, species
Answer:
option b is the correct answer
The correct order is kingdom, phylum, class, order, family, genus, species (C).
This sequence represents the classic Linnaean hierarchical classification system for animals, starting from the largest and most inclusive category (kingdom) to the smallest and least inclusive category (species). Here is a breakdown of each rank:
Kingdom: The highest and broadest taxonomic rank. Animals belong to the kingdom Animalia.
Phylum: The rank below kingdom. It groups animals based on certain characteristics or body plans.
Class: The rank below phylum. It further divides animals based on shared characteristics.
Order: The rank below class. It classifies animals based on similarities in anatomy and behavior.
Family: The rank below order. It groups animals based on common ancestry and shared traits.
Genus: The rank below family. It includes closely related species that share common characteristics.
Species: The lowest and most specific taxonomic rank. It represents a group of organisms that can interbreed and produce fertile offspring.

_________________________________[tex] \huge \red{Answer}[/tex]
the carrying away of the top fighter layer of soil by agents like wind and water is called soil erosion.
the top layer of the land has to be prevented from being eroded by natural force like strong winds or rain water this is done by planting more trees and making burns on the farm to prevent flow of soil during the rainy season.
how to prevent soil from Soil Erosion -:
afforestation - the best way to reduce our prevent soil erosion is by planting tree in large number the roots of tree hold the soil together plant also act as barrier for fast moving by they slow down the speed of wind.
construction of dam - it control flood.
terrace farming-: it is an effective way to minimise soil erosion in hilly area it is done by making step on hill slopes this reduce the speed of flowing water down The hills has reducing soil erosion.
Maggots can be used to help predict PMI for a body discovered
hidden among the tall weeds of field
twenty years after death
buried in a deep wet grave
on an ice flow off the Alaskan coast
Answer:
The answer is A, hidden among the tall weeds of field.
Explanation:
Maggots can no longer grow on a body that died 20 years ago. It would have dried out, making it a bad habitat.
It can't be buried in a deep, wet grave, because it would be hard for flies or maggots to get that deep into the soil, so they're going to look for easier options.
If a body was found on an ice flow off the Alaskan coast, it is far too cold for flies to lay eggs on the body.
This leaves "hidden among the tall weeds of a field," which doesn't say that the body has dried out, it's probably not too cold, and it's easy accessible to the flies that need to lay eggs.

Why does deforestation cause global temperatures to rise?
Select one:
Trees release oxygen into the atmosphere. Too much oxygen in the
atmosphere causes global warming.
Trees release nitrogen into the atmosphere. Too much nitrogen in the
atmosphere causes global warming.
Trees remove water vapor from the atmosphere. Water vapor is a greenhouse
gas that causes global warming.
Trees remove carbon dioxide from the atmosphere. Carbon dioxide is a
greenhouse gas that causes global warming.
Answer:
Trees remove carbon dioxide from the atmosphere. Carbon dioxide is a greenhouse gas that causes global warming.
Explanation:
Trees take in carbon dioxide and release oxygen. Deforestation gets rid of trees, so carbon dioxide is no longer being absorbed. Since carbon dioxide is a greenhouse gas, meaning that it traps heat in the Earth's atmosphere, too much of it causes global temperatures to rise.
