Answer:
The correct answer is: homologous chromosomes.
Explanation:
Diploid species like us humans have two sets of the same 23 chromosomes: 1 set of chromosomes is inherited from our mother, the other set we inherit from our father, making up a total of 46 chromosomes in every somatic cell (sexual cells have only one set of chromosomes - they're haploid).
<u>Two chromosomes are </u><u>homologous</u><u> when they belong to the same pair and have the same genetic information, although they can have a few variations</u>. These variations from one homologous chromosome to the other are called<em> alleles</em> and represent the different phenotypic variables that can result from the same gene. If these alleles are different from one another, only one of them will express itself (there are a few exceptions, like blood type) as the organism will be heterozygous for this trait; if the alleles are the same, the individual will be homozygous for the trait.
This is the basis for Mendelian inheritance.
Answer:
Temperature
water
glucose or sugar
Explanation:
Temperature is required as without it metabolic reactions in the body would be impossible.
Water is a medium for most metabolic reactions. This is why cytoplasm is 70% water.
Glucose levels need to be maintained as the glucose present is to be used as energy by being broken down.
<span>Step1; Like all strong winds and storms, tornadoes begin when the sun heats the surface of the land. As the warm, less heavy air begins to rise, it meets the colder, heavier air above it creating a strong circular wind. A wind shear is when two winds at different levels and speeds above the ground blow together in a location. </span>
<span><span>Step 2: </span>The faster moving air begins to spin and roll over the slower wind. As it rolls on, it gathers pace and grow in size.</span>
<span>
Step 3: At this stage, it is an invisible, horizontal wind spinning and rolling like a cylinder. As the winds continue to build up, stronger and more powerful warm air forces the spinning winds vertically upward, causing an updraft.
<span>Step 4: </span>With more warm air rising, the spinning air encounters more updraft. The winds spin faster, vertically upwards, and gains more momentum.</span>
<span>Step 5: At this stage, the spinning winds, creates a vortex and the wind has enough energy to fuel itself.
Step 6: The tornado is fully formed now and moving in the direction of the thunderstorm winds. When the pointed part of the tornado touched the ground from the cloud, it is often referred to as </span>'touch down'<span>
</span>
