Definition:
Having two different alleles of a particular gene or genes.
(an Allele is a variant form of a gene.)
Simplification:
If the organism has one copy of two different alleles, it is heterozygous.
Eg: T and t
<em> </em><em> </em><em> </em><em> </em><em> </em><em>(</em><em>T</em><em> </em><em>for </em><em>tall</em><em> </em><em>and</em><em> </em><em>t</em><em> </em><em>for</em><em> </em><em>short</em><em>)</em>
Example:
<u><em>Pea</em><em> </em><em>Plants</em></u>
Pea plants can have red flowers and either be homozygous dominant (red-red), or heterozygous (red-white). If they have white flowers, then they are homozygous recessive (white-white). Carriers are always heterozygous.
The condition known as endocervicitis is an aggravation of the bodily fluid film coating of the cervix. A condition in which patches of endometrial tissue get away from the uterus and wind up joined to alternate structures in the pelvic cavity.
In a few ladies endocervicitis is asymptomatic, now and again the accompanying manifestations might be available:
1-irregular seeping from the vagina;
2-constant dark or white release from the vagina;
3-vaginal agony;
4-torment amid intercourse;
5-feeling offensive distress in the little pelvis;
Much of the water vapor and carbon dioxide in earth’s atmosphere is found in the troposphere.
Answer:
spatial summation
Explanation:
There are two types of neuron summation:
- temporal-multiple repeated signals (target neuron receives a single form one neuron that is repeated)
- spatial-multiple simultaneous signals from multiple synapses (target neuron receives few different inputs).
Since the signals might be excitatory (produce depolarization of the postsynaptic cell) or inhibitory (produce hyperpolarization) of the postsynaptic cell, their total sum might or might not trigger an action potential on neuron.
C) matter is changed into various forms but the total quantity remains unchanged.
