Answer:
In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure. DNA and histone proteins are packaged into structures called chromosomes.

When Gregor Mendel crossed true-breeding tall plants with true-breeding short plants What type of inheritance is it?
Answer:
Complete dominance
Explanation:
Gregor Mendel (1822 - 1884) was regarded as the "FATHER OF GENETICS" due to his immense contribution to discovering the principles that govern inheritance in organisms. In one of his several experiments, he performed a cross between true-breeding tall plants (TT) and true-breeding short plants (tt).
From this cross, Mendel found out that the F1 generation were all tall. He self-crossed the F1 generation and obtained F2 offsprings in a ratio 3 tall: 1 short. This shows that the tall phenotype allele (T) is dominant over the short phenotype/allele (t), which was being masked in the F1 generation i.e. Tt. This inheritance pattern is called COMPLETE DOMINANCE.

Un fluido es todo cuerpo que tiene la propiedad de fluir, y carece de rigidez y elasticidad, y en consecuencia cede inmediatamente a cualquier fuerza tendente a alterar su forma y adoptando así la forma del recipiente que lo contiene. Los fluidos pueden ser líquidos o gases según la diferente intensidad de las fuerzas de cohesión existentes entre sus moléculas. Seleccione una: Verdadero Falso
Answer:
True.
Explanation:
Yes, fluids can be liquids or gases depending on the different intensity of the cohesion forces that exists between their molecules because these cohesive forces allows the molecules to attach to one another that leads to their state of matter. Cohesion forces such as hydrogen bonding and van der Waals forces are responsible for the bulk property of liquids that resisting separation from one another so due to these bonding, the molecules attach to one another on the basis of strong bonding between molecules.

What genes direct the
development or body plan of
organisms?
A. hox genes
B. beta genes
C. triage genes
Answer:
a. hox genes.
Explanation:
HOX genes have the following functions:
HOX genes are the homeobox subset.They specify the areas of the embryo's body plan along the animal head-tail axis.They are encoding Hox proteins that specify the position characteristics and ensure that the right structures form at the right position in the body.They regulate high-level executive genes, such as transcription factors and intracellular signaling molecules, which adhere, number, form, and growth to cells.The vertebrates are highly preserved.
The clusters and other genes occur uninterrupted.
Evolutionary, the heterogeneous regulatory areas between the genes most previously present are larger and more preserved than those present at the other ends of the clusters.
The characteristical feature is that these are homeodomain proteins with a highly preserved area of DNA binding encoded with homeobox gens.

Case Ico-delete Highlights
A 42-year-old woman presents for an evaluation of back pain. She states that she has a history of recurrent UTIs; she notes that on occasion her urine appears red. Upon physical examination, she demonstrates CVA tenderness. Her vital signs include blood pressure of 145/90 mm Hg, respiratory rate of 16 breaths/min, and heart rate of 72 bpm. Urinalysis shows leukocyte esterase 1+, protein trace, and blood 3+. The microscopic examination reveals 5-10 WBCs/hpf and 20-30 RBCs/hpf. An abdominal ultrasound demonstrates multiple, bilateral fluid collections within the kidneys.
Question
What, if any, is the most likely underlying renal pathology?
Answer:
The correct answer would be - polycystic kidney disease.
Explanation:
The given clinical picture or information suggests that it is most probably an infection that takes place in one or both the kidneys and leads to the setting of polycystic kidney disease.
The given symptoms such as abdominal or flank pain, recurrent UTIs, blood in the urine, and hypertension are characteristic symptoms of polycystic kidney disease. Cystic lesions found on abdominal ultrasound are a confirmation of the disorder.
The key disease of this polycystic disorder is Goodpasture syndrome which shows symptoms of both glomerulonephritis and pulmonary hemorrhages, and medullary sponge kidney disorder.

how does blood works?
Answer:
Blood is a mixture of two components: cells and plasma. The heart pumps blood through the arteries, capillaries and veins to provide oxygen and nutrients to every cell of the body. The blood also carries away waste products.
The adult human body contains approximately 5 liters (5.3 quarts) of blood; it makes up 7 to 8 percent of a person's body weight. Approximately 2.75 to 3 liters of blood is plasma and the rest is the cellular portion.
Plasma is the liquid portion of the blood. Blood cells like red blood cells float in the plasma. Also dissolved in plasma are electrolytes, nutrients and vitamins (absorbed from the intestines or produced by the body), hormones, clotting factors, and proteins such as albumin and immunoglobulins (antibodies to fight infection). Plasma distributes the substances it contains as it circulates throughout the body.

This fly has 14 chromosomes in its cells.7 maternal chromosomes and 7 paternal chromosomes.Assume you are a microscopist viewing this fly cells that are undergoing meiosis. Conclude the number of chromosomes/chromatids at the end of meiosis 1 as well at the end of meiosis 2. please answer!!!!!
Answer:
23 pairs in meiosis 1 and 23 numbers in meiosis 2.
Explanation:
There are diploid number of chromosomes means double number of chromosomes at the end of meiosis 1 while on the other hand, at the end of meiosis 2, there are haploid number of chromosome means half number of chromosomes in each daughter cell. In humans meiosis 1, there are 23 pairs of chromosomes that is diploid in nature but in the end of meiosis 2, there are only 23 chromosomes in each daughter cell which is haploid in nature.

when people suffer from chicken box they shed skin when the Pox dries it is recommended by the daughters that the skin shade by the patient should be burnt away and not be directly test why do you think this precaution is mandatory
Answer:
because the precaution is skin shade by the patient should be burned away and not be directly test
Answer:
People suffering from chickenpox should not be in sunlight because the skin is more susceptible to heatstroke. The virus stays for a long time in the body, even after the symptoms are gone. Hence, it is recommended to burn it.

If both maize and teosinte are grown in the wild, which species is more likely to proliferate? Why?
Answer:
he maize is more likely to proliferate because of the human effect.
Explanation:
If both maize and teosinte are grown in the wild, teosinte is more likely to proliferate. This is because teosinte has certain adaptations that make it better suited to the wild environment.
What are maize and teosinte?Maize and teosinte are both members of the grass family, but they differ in several important ways. Maize, also known as corn, is a domesticated crop that has been selectively bred over thousands of years to produce larger, more desirable ears for human consumption. Maize has a much larger ear size than teosinte, and its kernels are also larger and more closely packed together.
Hence, if both maize and teosinte are grown in the wild, teosinte is more likely to proliferate. This is because teosinte has certain adaptations that make it better suited to the wild environment.
