Answer:
RrYy (F1 generation)
Explanation:
This is a typical dihybrid cross involving two genes in the pea plant; one coding for seed colour and the other for seed shape.
According to Mendel's law of dominance, an allele is capable of masking another allele in a gene, the allele that masks or is expressed is called the DOMINANT allele while the allele being masked is called RECESSIVE allele.
Homozygosity of a gene refers to it having the same type of alleles while heterozygosity refers to having different alleles.
In this example, allele for Round (R) and Yellow (Y) pea is dominant over the allele for Wrinkled (r) and green pea respectively.
Homozygous round green pea (RRyy) crossed with Homozygous wrinkled yellow (rrYY) will give rise to a heterozygous round yellow (RrYy) F1 offsprings.
Answer:
Epimysium
Explanation:
The muscle fibers of a skeletal muscle are surrounded by three layers of connective tissues to form a muscle. The three layers of connective tissues are –
a) Endomysium – It is the inner most layer of connective tissue that surrounds all the muscle fiber
b) Perimysium – This layer lies above the endomysium and forms a fascicle
c) Epimysium – This is the outermost layer of the connective tissue surrounding the skeletal muscle. Epimysium form a complete muscle by encircling the fascicle
Your best bet is most likely going to be B
A Chromosome holds part or all of the genetic material of an organism. It also includes packaging proteins which, aided by chaperone proteins, bind to and condense the DNA molecule to prevent it from becoming an unmanageable tangle.
So yes your best bet is B.

Macaws (parrots), monkeys, capybaras, and grasshoppers, frogs, iguanas and vampire bats.
