You did not provide an image for me, but I can explain.
Homozygous, with the root homo, means same. Therefore, a guinea pig parent with homozygous traits would have the traits being the same - either both recessive or both dominant, ie TT, tt.
Heterozygous on the other hand means different, therefore the traits would be one dominant and one recessive - for example, Tt.
If for the punnet square it has different traits (Combo RB for red and black or combo RW red white for like fur color) than heterozygous would be any that isn’t like TT or tt or any other letters used.
Hope this helps!
        
             
        
        
        
Answer:
Fertilized human egg becomes a solid ball of cells known as morula which then differentiate into blastocyst to fully grown human baby.
Explanation:
1.	As the zygote is formed it starts to divide and multiply while moving toward the uterus to form a blastocyst within five days.  
2.	The blastocyst attaches to the wall of the uterus by implanting itself to the uterine lining
3.	Within the 15 days of conception, placenta and umbilical cord starts developing to bring in nutrients and eliminate waste
4.	The embryo differentiates into three layers- a) the endoderm, b) the mesoderm, and c) the ectoderm. These three layer form different parts of the body  
5.	By end of 4 weeks, embryo develops distinct head, tail and heart
6.	By end of 10th week, limbs, eyes, brain regions, and vertebrae form
7.	Around week 36 labors begins.  
 
        
             
        
        
        
Answer:
The gene, or sequence of DNA, ultimately determines the unique sequence of amino acids in each peptide chain. A change in nucleotide sequence of the gene's coding region may lead to a different amino acid being added to the growing polypeptide chain, causing a change in protein structure and therefore function.
 
        
             
        
        
        
B. False
Totally incorrect. Some pathogens and microorganisms that is blood-borne can transfer itself from one individual to another by blood and fluid contact. This is a much stronger affinity for the pathogen to spread from the host to the person transferred to.
