Heterozygous means two alleles are different. In this case, it means one is dominant (P) and the other one is recessive (p).
So genotype of both parents are Pp.
The problem can be solved quickly with a Punnett square:
P p
P PP Pp
p Pp pp
So genotype/phenotype
25% PP polka-dot tail
50% Pp polka-dot tail
25% pp solid-coloured tail
So for genotypes:
PP 25%
Pp 50%
pp 25%
For phenotypes:
75% polka-dot tail
25% solid-coloured tail
Nucleus - regulates all cell activity, and also holds the DNA
Smooth endoplasmic reticulum - lipid and carbohydrate synthesis.
Rough er - produces and modifies proteins
Located next to the nucleus
Golgi apparatus - <span>modify, sort, and package macromolecules for cell secretion </span>
Ribosome - <span> assembles the twenty specific amino acid molecules to form the particular protein molecule</span>
Mitochondria - converts energy into compounds that are easier for the cell to use
Chloroplast -<span> captures the energy from sunlight and converts it into food that contains chemical energy in a process called photosynthesis</span>
Lysosomes - breaks down, recycles macromolecules (lipids, carbohydrates, and proteins)
Perioxisome - where hydrogen peroxide and other harmful molecules are broken down by enzymes
Plasma membrane - controls the kinds and amounts of substances moving into and out of the cell; helps maintain cytoplasmic volume and composition
Cytoskeleton - structurally supports, impacts shape and moves cell and its componants
Centrioles - two perpendicular cylinders that form mitotic spindle fibers and microtubules for cilia and flagella, helps organize cell division
Cytoplasm - holds all organelles in place
Vacuole - stores water, salts, protein, and carbohydrates
Vesicles - <span>contains substances that recently entered the cell. Stores and transports newly synthesized molecules.</span>
Cell wall - supports and protects the cell, rigid barrier
Answer:
cell
Explanation:
The cell is the basic structural and functional unit of life. Cells are independent, single-celled organisms that take in nutrients, excrete wastes, detect and respond to their environment, move, breathe, grow, and reproduce.
A. TRUE
These are grouped as the term "gonadotropins" because they affect the gonads.
<span>A: The efforts of one good worker can often motivate others to reach their potential through a process called modeling.</span>
