Answer;
Alleles are passed from the parents’ sex chromosomes to the sex chromosomes in the offspring.
Explanation;
-Sex linked traits are traits that are carried by the sex chromosomes and inherited together.
-Gene exists in alternative forms called alleles and each allele for a trait is inherited from each parent.
-Sex traits, like the other traits, are passed from parents to off spring through the process of sexual reproduction.
Some molecular studies point to amphibians descending from the lung fish, the Diponi.
Under the class Amphibia, amphibians are tetra-pod, cold blooded vertebrates without having scales. Protein is produced by the special skin of Amphibians.
Lung fish belong to the subclass of Diponi, these are living air breathing species.
<span>Selective breeding in the process of choosing the best characteristics of organisms through many generations to improve the variety or breed of the organsism:
TRUE, SELECTIVE BREEDING IS AN ARTIFICIAL PROCESS THAT BREEDERS CAN APPLY TO PLANTS AND ANIMALS TO ENHANCE PARTICULAR TRAITS, SUCH AS SIZE.
</span>
Humankind has domesticated animals over thousands of years for the sole purpose of companionship.<span>
FALSE. WHILST DOGS AND CATS HAVE BEEN BRED PARTLY FOR COMPANIONSHIP, DOMESTICATION OF ANIMALS HAS BEEN ESSENTIAL FOR SURVIVAL THROUGH ENHANCING FOOD PRODUCTION AND TRANSPORT. KEY EXAMPLES INCLUDE COWS AND HORSES.
</span>
The remains of wild dogs were found among the prehistoric bones of our ancestors who lived thousands of years ago.
TRUE. DOGS WERE DOMESTICATED OVER 4000 YEARS AGO ORIGINALLY FROM WOLVES.
<span>Cats are the most domesticated animals in the world.true or false
</span>TRUE. THIS ONLY APPLIES TO SMALL HOUSE CATS AND NOT THE WIDER CAT FAMILY
<span>Animals like leopards,wolves,tigers,bears, and skunks could never be tamed enough to live with people.
FALSE. THIS QUESTION IS CONTROVERSIAL HOWEVER GIVEN ENOUGH GENERATIONS IT IS LIKELY THAT ANY ANIMAL CAN BE DOMESTICATED. MODERN DOGS ARE DERIVED FROM WILD WOLVES.
</span><span>Tamed wild animals that have even been born in captivity and never been in the wild,are considered domestic. True or false
FALSE. DOMESTICATION COMES THROUGH MULTIPLE GENERATIONS
</span><span>Selective breeding is the only method to change life forms characteristics. True or false
FALSE. SELECTIVE BREEDING IS AN ARTIFICIAL FORM OF EVOLUTION. EVOLUTION THROUGH NATURAL SELECTION IS OCCURRING CONSTANTLY IN NATURE AND IS THE PRIMARY MECHANISM DRIVING CHANGES TO LIFE FORMS/CHARACTERISTICS.</span>
Answer:
It is (x+y)t miles from the school to Bob's home
Explanation:
Assuming the distance from Bob's home to school is d miles and the time taken is t hours
Distance covered when he had flat tire = d/2, time taken = t/2, rate = x miles/hour
Rate = d/t
x = (d/2)/(t/2)
d = xt miles from Bob's home to halfway the school
distance from halfway the school to the school = d/2, time taken = t/2, rate = y miles/hour
rate = d/t
y = (d/2)/(t/2)
d = yt miles
Total distance from school to Bob's home = xt + yt = (x + y)t miles
