Answer:
Through natural selection, those organisms which have better adaptations to survive in an environment are able to live and pass on their alleles to their offsprings. Hence, any trait which is beneficial to an organism will be favoured by natural selection.
As tissue pockets is a trait which is required by the shrimps, hence with the passage of time shrimp population having tissue pockets will increase and will be favoured by nature.
So here we have two heterozygous organisms that will mate. You can put them into a Punnet square, just to be sure of your answers and to find all possible genotypes :
R r
R RR Rr
r Rr rr
So you have RR, Rr and rr as your possible genotypes.
The correct answer is the homeostasis.
A plant may close and open its stomata to prevent excess water loss and maintain homeostasis.
Homeostasis is termed as the tendency of organisms to maintain and automatic regulation of their internal environment to be in a stable condition.
We say that the plant is in stable condition when the fluid balance and body temperature are being kept in to a pre-set limits which include calcium ions, potassium, sodium and PH of extracellular fluid.
The natural resistance which changes the optimal condition brings about homeostasis.
The right matches are :
A. bryophyte ==> 3.
B. pteridophyte ==> 2.
C. gymnosperm ==> 1.
D. angiosperm ==> 4.
These four types of plants are cormophytes.
Bryophyte is a terrestrial plant belonging to the family Bryophyta, which does not have a real vascular system.
Gymnosperms are the first order of didynamy containing phanerogamous plants whose eggs are not enclosed in closed carpels.
Angiosperms are plants whose seeds are enclosed in a closed ovary.
Pteridophytes produce neither flowers nor seeds but are vascular plants.
Answer:
Unlike most nonmammalian animals, scorpions are viviparous, giving birth to live young instead of laying eggs. Once fertilized, the eggs are retained in the female's body, where the embryos are nourished in utero for periods varying from several months to a year.
