If you are to conduct a DNA analysis using a blood sample which of the blood components will you use
Options :-1.) Red Blood Cells
2.) White Blood Cells
3.) Plasma

Answer:-Option 2.) White Blood Cells
Explanation:- Red Blood Cell(RBC) , Plasma , Platelets lack DNA White Blood Cell (WBC ) only have DNA RBC lack nucleus to make space for O2 as the work is to carry O2 with help of hemoglobin Platelets are the cell fragments of the large cells they help in clotting so too lack nucleusPlasma is the fluid part of the blood. so it contain water in its most part and too lack DNA bez plasma don't contain any cells WBC are the only cells which have well defined nucleus with DNA in above mentioned optionsFor which of the following reasons does a 3-column organizer help you retain

The genetic recombination occurs in meiosis during the stage of Prophase I.
What do you mean by Genetic recombination?
Genetic recombination may be defined as the conditions when the molecules of the DNA exchange their genetic material with each other.
This process of genetic recombination also known as crossing over, which is responsible for the genetic diversity among individuals.
Genetic recombination occurs when homologous chromosomes are arranged in pairs and interchange the segments of the DNA.

Thoroughly analyze the alguments made in the article regarding potential
evolutionary links between the australopithecines and the ancestors of
the genus Homo. What evidence is provided by the author to conclude
that the later paranthropoids were not direct ancestors of modern
humans? Is this evidence sufficient to support his claim? Why or why not?
Extinct species of hominins known as Australopithecus may have been the ancestors of modern humans (Homo sapiens). The first fossils, which were found in South Africa, are referred to as Australopithecus.
After almost a century of findings, the first species to be called Australopithecus was given that name in 1925, and today, paleoanthropologists may access a sizable collection of fossilized hominin remains from Africa. High-quality fossils of early human species are still very hard to find despite decades of research, making it even more important for scientists to continue finding them in order to better understand the biology and variety of Australopithecus. The Great Rift Valley in eastern Africa, the limestone caves of South Africa, the sedimentary deposits of the Chad Basin, and the Djurab Desert are the only places on earth where geological circumstances are favorable for the preservation and excavation of hominid fossils (an arid region in central Chad).Learn more about the Australopithecus with the help of the given link:

Study the cladogram. Which two organisms have dry skin? gorilla and shark shark and lizard lizard and tiger tiger and lamprey.
Answer:
It's C.
Explanation:
I chose B but I got it wrong. Since lizards obviously have dry skin, the other option with lizards is C. And you can also see in the cladogram that above "dry skin" is lizards and tigers.
So it's C.
The relationship between the two organisms is represented by a cladogram. Here, dry skin is seen in lizard and tiger. Thus, option c is correct.
What is a cladogram?Cladogram is based on the evolutionary relationship between the organisms and how closely they are related to each other. It is expressed in the form of branching diagram.
In cladograms, the morphological features are included. However, advanced cladograms can be constructed using DNA or RNA sequencing.
Cladograms are useful tools for studying evolution as they are represented through simple diagram. The advantage of using cladogram is that it includes only the pure characters. No derived characters are taken into account.
Thus, cladograms are important in determining the evolutionary relations amongst the taxonomic groups.

How many chromatids and
strands of DNA?
Answer:Neuronal cells in G2 phase demonstrate tetraploid (4N) DNA content or, more precisely, possess a nucleus with 46 replicated chromosomes.
Explanation:In the G1 phase, there are 12 chromosomes. In the S-phase of the cell cycle, the amount of DNA gets doubled. There is doubling of the chromatids but the chromosomes number remains same. The number of chromosomes in the G2 phase will be same as 12 chromosomes and the number of chromatids will be 24.
Which best describes the movement through the nephron?
A. Blood is passed into the nephron and removed through the urethra.
B. All materials that exit the blood into the nephron are removed in the urine.
C. Some of the materials that exit the blood can be returned to the blood.
D. High quantities of sugars and water are excreted in the urine.
Some of the materials that exit the blood can be returned to the blood is the best description of the movement through the nephron. Therefore, the correct statement is option C.
What is the nephron?The nephron is the functional unit of the kidney that is responsible for filtration of blood, regulation of the balance of fluids and electrolytes, and removing waste products from the body.
It is filtered by the glomerulus as blood flows through the nephron, and the filtrate then passes through the renal tubules, where substances such as glucose are reabsorbed back into the bloodstream.
The process is important for maintaining the homeostasis of the body, such as regulating blood pressure and the remaining waste products are excreted out of the body in the form of urine through the ureters and urethra.
Therefore, the materials that exit the blood can be returned to the blood is the best description of the movement through the nephron.
