What is the diploid number of dog chromosomes?
The number of chromosomes does not correlate with the apparent complexity of an animal or a plant: in humans, for example, the diploid number is 2n = 46 (that is, 23 pairs), compared with 2n = 78, or 39 pairs, in the dog and 2n = 36 (18) in the common earthworm.
How many chromosomes are in a dog?s haploid cells?
There are 39 chromosomes in their haploid cells.
What is the chromosome number of dog?
Chromosomes are found in pairs within the cell. Each cell contains two separate copies of each gene (alleles). While a human has 46 chromosomes (23 pairs), a cat has 38 chromosomes (19 pairs) and a dog has 78 chromosomes (39 pairs).
How many chromosomes do dogs have after mitosis?
Each dog?s gamete is produced from a process of meiosis and carries 39 chromosomes.
How many chromosomes do dogs have in a sperm cell?
There are 39 chromosomes in a dog sperm cell and 39 chromosomes in a dog egg cell. When combined they have a total of 78 chromosomes.
What does each chromosome mean in dogs?
Each chromosome in a dog contains codes for hundreds to thousands of genes. Each gene has a specific code that?s passed from parent to offspring. Genes determine how your dog will develop everything from fur color and personality traits to his breed and inherited diseases your dog may be prone to.
How many chromosomes are in a daughter cell in a dog?
2. 72 chromosomes. As stated above, the daughter cells are identical to the parent cells and have the same amount of chromosomes.
What does haploid mean in terms of chromosomes?
Sexually reproducing organisms are diploid (having two sets of chromosomes, one from each parent). In humans, only their egg and sperm cells are haploid. Haploid refers to a cell or an organism that has only a single set of chromosomes. This is to be contrasted with diploid.
What are the chromosome numbers of all animals?
Chromosome Number of various Animals Animal Chromosome number 1. African wild dog (Lycaon pictus) 78 2. American badger (Taxidea taxus) 32 3. American marten (Martes americana ) 38 4. American Mink (Neovison vison) 30
What?s the chromosome number of an African wild dog?
1. African wild dog (Lycaon pictus) 78. 2. American badger (Taxidea taxus) 32. 3. American marten (Martes americana )
How many diploid chromosomes are there in the human body?
The diploid chromosome number is 2n = 14 with four pair of long acrocentric chromosomes ranging from 14.4 ?m to 17.9 ?m and three pair of short sub metacentric chromosomes ranging from 4.6 ?m to 5.4 ?m.
What is the direction of magnetic field at the centre of a coil carrying current in a anticlockwise direction?
When the current flows through the solenoid in the anticlockwise direction, then the magnetic lines of force inside or center of the coil will be along the axis outwards according to right hand thumb rule.
What is the direction of the magnetic field at the centre of the coil if the current in the coil is reversed then what will be the direction of the magnetic field at the centre of the coil?
When the current is reversed, the direction of the magnetic field through the centre of the coil and around the wires is reversed. The magnetic field is strongest inside the coil. This is because the effects of both sides of the vertical part of the wires add up at the centre.
What happens when the current through the coil is reversed?
The magnetic field generated is always perpendicular to the direction of the current and parallel to the solenoid. Hence if we reverse the current the direction of magnetic field also reverses.
How do you calculate the area of a coil?
The area of a circle is and r is half of the diameter. r = d/2 implies r^2 = d^2/4 ?
Where is the strongest magnetic field in a coil?
The strongest external magnetic fields are near the poles. A magnetic north pole will attract the south pole of another magnet, and repel a north pole.
What happens to magnetic field when current is increased?
The small magnetic fields caused by the current in each turn of the coil add together to make a stronger overall magnetic field. The strength of the magnetic field around a solenoid can be increased by: increasing the number of turns on the coil. increasing the current.
What is the purpose of current coil and pressure coil in wattmeter?
While the pressure coil is connected in parallel with the load. Moreover, the current coil measures the current while the pressure coil measures the voltage. Both the coils are used in a wattmeter scale and to measure current or voltage in tension transmission lines.
How do you calculate the weight of a coil?
The coefficient 1000000 is used to compensate the dimensions of Volume (mm^3) and Density (kg/dm^3). The following graph is an interesting tool, showing the weight per millimeter of width of a steel coil with ID 508mm. For example, the same steel coil with OD = 1600mm, ID = 508mm, W = 250mm has a weight of 3500 kg.
What is the formula for inductance of a coil?
The formula is: The micro henrys of inductance in a coil = (N^2)(D^2)/(18D + 40L) where ?N? equals the number of rings in the coil, ?D? equals the diameter of the coil and ?L? equals the length of the coil.
Where is the magnetic field at the center of a coil?
Outside the coil or solenoid, that is, at the ends and beyond the magnetic field is small and appears to diverge. When the current flows through the solenoid in the anticlockwise direction, then the magnetic lines of force inside or center of the coil will be along the axis outwards according to right hand thumb rule.
How is the magnetic field produced in a circular wire?
It means that when the current flows in a circular wire (coil), the magnetic field produced has straight lines of force near the centre of the coil, as shown in figure. The parallel lines are in a plane perpendicular to the plane of the coil.
Which is the direction of the magnetic field?
The direction of the current is by convention the direction in which positive charges move. The direction of the magnetic field is in the direction the fingers of your right hand would curl, if you wrapped them around the wire with your thumb in the direction of the current. Magnetic field of a loop.
Where is the magnetic field located in a solenoid?
Perpendicular to the axis of coil inwards. Perpendicular to the axis of coil outwards. Along the axis of coil inwards. Along the axis of coil outwards. Along the axis of coil outwards. A solenoid is a long coil of wire wrapped in many turns. The magnetic field within a solenoid depends upon the current and density of turns.
