Answer:
The question lacks options and the incomplete punnet square; the incomplete punnet square has been added as an attachment while these are the options:
A) All red flowers
B) All pink flowers
C) 1 red : 3 pink flowers
D) 3 red : 1 pink flowers
The answer is D
Explanation:
According to the question, the genotype of a plant that produces red flower phenotype is about to be determined. For this flower colour gene, two alleles are involved in which the red color (R) allele is dominant over the pink color (r) allele I.e. the R allele will mask the expression of r allele in a heterozygous state.
The red-flowered plant with unknown genotype was crossed with a heterozygous red-flowered plant (Rr). Since a red flowered plant can either be Rr (heterozygous) or RR (homozygous), we use the Rr plant in the punnet square. The unknown genotype, assuming it has a Rr genotype, will produce RR, Rr, Rr and rr offsprings when crossed with another heterozygote (Rr).
These offsprings show a 3 red : 1 pink phenotypic ratio, making option D a valid prediction.
R r
R RR Rr
r Rr rr
Monocot :) is the answer, good luck!!
Answer:
circulatory and respiratory
Explanation:
The body system of Birds possesses a higher arrangement of organs to perform a particular function. The organs form a system which includes the organs and associated structures.
When the biologist observed the shortage of the dissolved oxygen and increase in the level of dissolved carbon dioxide, this could be the result of the failure of the circulatory system which supplies these gases on the body and the associated respiratory system which helps in the exchange of these gases with the atmosphere.
Thus, circulatory and respiratory is the correct answer.
oxygen flow is low and his lungs do not have a lot of capacity
The answer is pronuclei. A pronuclei is the state of the
nucleus of either the sperm or the ovum after the sperm has entered the ovum
but the two nuclei have not yet fused. When the sperm enters the ovum, the membrane
of the sperm pronuclei dissolves hence leaving no barrier for the two genetic
materials to combine.
