The correct pairing of DNA bases A. T with A, and C with G. Thus, option "A" is correct.
How, explain your answer briefly?It can be explained with the help of complementary base pairing.
In DNA, thymine (T) always forms a base pair with adenine (A) and cytosine (C) always base pairs with guanine (G) .
There are two hydrogen bonds present in between A and T and three hydrogen bonds in between G and C.
Thus, option "A" is correct.

In a quadrat that is 0.5m along each side, you count 3 daisy
plants and 25 grass plants. The whole lawn you are sampling
is 5m long and 4m wide. Calculate the number of daisy plants
and grass plants in the whole lawn. Show your working
clearly.
Answer:
Interdependence is a key concept in ecology. Whilst this can be taught theoretically, some practical fieldwork greatly enhances pupils’ understanding. Almost certainly the fieldwork would entail looking at plant abundance and distribution and, of course, some work with quadrats!
A quadrat is a simple device for marking out a small area. For young children at primary school the quadrat is often a convenient way of focusing a pupil’s attention on a particular small area. At secondary level, pupils should understand how quadrats can be used to sample a larger area. By recording information from a number of quadrats placed within a larger study area, they can obtain a representative sample of the whole area, which may be too big to describe in full.
This article describes how quadrats can be used to help pupils at lower secondary level estimate the relative abundance of plant species. All the information given here refers to frame quadrats. (Point quadrats can be tedious and difficult for pupils to use and are probably best avoided at this level.
which of the following is an enzyme required by the process of rephosphory,to create ATP? A) AD Pase B)AT Pase C)Polymerase D)AT synthase ?
ATPase is the enzyme which is required to create ATP and is denoted as option B.
What is ATPase?This type of enzyme is found in the mitochondrion and catalyzes the formation of ATP which provides energy to cells.
The ATP which is referred to as adenosine triphosphate is formed from the molecules known as ADP and inorganic phosphate which are present in the body cells. This ensures that the daily energy needs of the body are met.

The mitochondrial DNA sequence that is shared by two species has a steady mutation rate. Scientists determine the sequences of these two species to be as follows
Species A: CAGGCCATTATG
Species B: CCAGCCTATAGG
Based on this information, which of the following best explains the difference in the DNA sequence between the two species?
A) Species A and B probably share the most recent ancestor because they only differ by three mutations.
B) Species A and B have fewer differences between DNA sequences means that fewer mutations occurred.
C) Species A and B probably have distinct ancestors because they have many differences in mutations.
D) Species A and B are closely related because they differ by five mutations in their DNA sequence.
It is expected that Species A and B have distinct ancestors because they have many differences in mutations (Option C).
What is the mutation rate?The mutation rate makes reference to the number of mutations that appeared in a given nucleotide sequence in a given period of time.
In this case, sequences from Species A and B have 5 mutations and aligned sequences have only 12 nucleotides, which is a considerably high mutation rate to share a common origin.
Nonetheless, information about divergence times might be helpful to determine the origin of these sequences.
In conclusion, nucleotide sequences of Species A and B exhibit many mutations and therefore they do not have the same evolutionary origin (Option C).

what is the difference between an epithelial cell and a cardiomyocyte
The heart is the main pumping organ of the body. The human heart is divided into four chambers two atria and two ventricles. The human heart consists of three layers- epicardium, myocardium, and endocardium.
The middle layer of the heart (myocardium) consists of cardiomyocytes or muscle cells. These cells receive nerve stimulation from the atrioventricular nodes and sinoatrial nodes.
What are Epithelial cells?Epithelial cells form a layer structure which covers most of the surfaces of the body. These cells perform a variety of functions and exhibit different shapes, size and arrangement which makes up different tissues. For example columnar tissues (column-like cells), cuboidal tissues (cube-like cells) and others.

untrained individuals (I just need 3 adaptations listed). Please and thank you for your help in advance
Greater force of contraction, volume of blood ejected, and cardiac output result in aerobically trained individuals with greater stroke volume compared to untrained individuals
What increases stroke volume?A greater force of contraction consequently increases the volume of blood ejected with each systole (Systolic Volume). Increasing the stroke volume also increases, as a consequence, the cardiac output (CO = VS x HR).
With this information, we can conclude that greater force of contraction, volume of blood ejected, and cardiac output result in aerobically trained individuals with greater stroke volume compared to untrained individuals
