Conception- This is when the egg and the sperm unite at conception, it is the fertilization and starts at the woman’s fallopian and the fertilized egg , First Trimester
- First four weeks of the conception-, Second Trimester- This is 3 months after conception and this is where the baby can be felt kicking and can hear,Third Trimester- 28 weeks after conception and is having breathing movements and the women would be adding some body fat. If I am wrong please let me know
The answer is Rr and rr.
We know:
r - recessive allele
R - dominant allele
RR - dominant homozygote with red eyes
Rr - heterozygote with red eyes (since one dominant allele R can mask recessive allele r)
rr - recessive homozygote with sepia eyes
Heterozygote Rr can give to the offspring either dominant allele R or recessive allele r. Recessive homozygote rr can give to the offspring only recessive allele r (take a look at the uploaded image of Punnett square).
After crossing the parents:
Parents: Rr x rr
Offspring: Rr rr Rr rr
So:
2 out of 4 offspring will be with heterozygous with red eyes Rr: 2/4 = 0.5 = 50%
2 out of 4 offspring will be with homozygous with sepia eyes rr: 2/4 = 0.5 = 50%
It's definitely not A. since the toxins would kill butterflies. B. doesn't seem relevant. C. doesn't make sense because the toxins in the pollen are to protect the corn not to make new strains. So, the answer would be D. The carbon dioxide level would increase in the area. Hope this helps!
Answer:
Después de la fecundación, la célula recién formada llamada cigoto lleva a cabo divisiones sucesivas hasta desarrollar un nuevo individuo. Estas divisiones se llevan a cabo mediante el proceso llamado<u> segmentación.</u>
Explanation:
Luego de que se produce la fecundación del óvulo y se forma el cigoto, los 3 a 4 días que le siguen abarca un proceso llamado <u>segmentación</u>. En este proceso se producen <u>sucesivas divisiones celulares</u> dando blastómeros, los cuales son células que forman el embrión y a las estructuras que este necesita para desarrollarse. La segmentación es un proceso que ocurre en las trompas de falopio mientras el cigoto se desplaza hacia el útero donde se implantará.
Answer:
Explanation:
ADP (Adenosine diphosphate) is a starting material in respiration. Through the process of respiration a 3rd phosphate is added to the compound to make it ATP (Adenosine Triphosphate). This extra phosphate in the end product is what allows the cell to use the compound for energy.
NAD and NADH are used in the electron transport chain but not going to be the energy molecule
