Aleksandr [31]

Answer:

Explanation:

Given:

Traits

T (tall, dominant) and t (short)

R (round, dominant) and r (wrinkle)

Crossing parents

hetero-zygous. tall wrinkled (Ttrr)

phenotype tall is given hetero-zygous., so Tt

phenotype wrinkled is recessive, so must be homo-zygous rr

Foiled genotypes (Tr, tr, each with 50%)

short hetero-zygous. round (ttRr)

phenotype short is recessive, so homo-zygous rr

phenotype round is given heteroz. so Rr

Foiled genotypes (tR, tr, each with 50%)

The renal corpuscle consists of a capillary bed called the ____________ and a capsule of epithelial cells.

pychu [463]

The renal corpuscle consists of a capillary bed called the glomerulus and a capsule of epithelial cells. The renal corpuscle is composed of two structures, the glomerulus and the Bowman's capsule. The glomerulus is a small tuft of capillaries containing two cell types. It is also characterized as a cluster of capillaries around the end of a kidney tubule, where waste products are filtered from the blood. Other surfaces that separate body cavities from the outside environment are lined by simple squamous, columnar, or pseudostratified epithelial cells.The gastrointestinal tract, the insides of the lungs, and the reproductive and urinary tracts where other epithelial cells line up make up the exocrine and endocrine glands.

What does the number of electrons on the outer energy level of an atom tell you

adell [148]

Well, first off it tells you the number of valence electrons (because that’s what those are valence electrons) it also tells you how that atom is going to bond with other atoms (whether it will tend to loose or gain electrons when in chemical bonds). It also can show how reactive an element is (if it has eight or in some cases two then it won’t react because that outer shell is full)...basically it tells you the chemical properties of that atom
