Answer:
Axis - B
Rotation - E
Revolution - D
Latitude - A
Gravity - C
Explanation:
The axis is the line that a body spins on. The axis will line up with the north and south poles. For Earth, the axis is tilted, which is why seasons exist.
The definition of rotation is "the action of rotating around an axis or center." So, rotation is the spinning of a body on its axis. On Earth, one rotation is equal to one day.
Revolutions are when a body spins around another. For Earth, one revolution around the sun is one year
Latitudes are invisible lines that separate the world into degrees from North to South. They are also called parallels.
Gravity is the force that keeps things together. Large masses have gravity that attract other masses.
Answer:
16/64 = 1/4
Explanation:
This is a typical trihybrid cross involving three genes T, P and Y. A plant with genotype TTPpYy is crossed with a plant recessive for all traits (ttppyy).
According to Mendel's law of independent assortment, each allele for each gene will get sorted into the following 8 gametes with only 4 different: TPY, TPy, TpY, Tpy, TPY, TPy, TpY and Tpy.
The recessive parent, ttppyy will produce tpy, tpy, tpy, tpy, tpy, tpy, tpy and tpy.
Hence, using a punnet square, 64 offsprings will be produced with only 16 of them heterozygous dominant for the three traits with genotype (TtPpYy). Hence, proportion is 16/64 equivalent to 1/4.
Answer:
true
Explanation:
DNA synthesis is performed by the enzyme DNA polymerase. However, DNA polymerase requires the presence of a free 3' OH on the existing DNA or RNA segment. The enzyme primase forms small RNA segments that serve as primers. Primers are formed by using the DNA template strands and have free 3' OH ends. DNA polymerase extends the primers by adding deoxyribonucleotides according to the sequence of the DNA template strand. Therefore, DNA polymerases are the enzymes of primer elongation.
In alimentary canal, food get digested by the action of many enzymes secreted by various glands including Liver, Pancreas and salivary glands....
Answer:
The gastrovascular cavity is a structure found in primitive animal phyla. It is responsible for both the digestion of food and the transport of nutrients throughout the body. The cavity has only one opening to the environment. Food goes in and waste comes out that same opening, making it a two-way digestive tract
