Answer:
sporopollenin
While the exine is composed of sporopollenin, a complex and highly resistant biopolymer containing fatty acids, phenylpropanoids, phenolics and carotenoids, the intine is largely composed of pectin and cellulose.
Explanation:
Answer:
In an experiment, the researcher needs to have a control group with an experimental group where both groups are identical in every way except that the controlled group does not gets the experimental treatment.
Sometimes, it is not possible to do a test or the experiment utilizing a controlled trial (due to ethical reasons or no practical method available). All things considered, a researcher may test a theory by making predictions about outcomes or patterns that ought to be found in nature if the hypothesis is right.
Mmmm yes mmmm yes 7% i believe so
Answer:
Mitosis, Meiosis, and both are written below
Explanation:
Mitosis: produces more somatic (body) cells, purpose is for healing and growing, the daughter cells are exact replicas
- This is because mitosis occurs in body cells and is used for growth, so all the daughter cells are the same.
Meiosis: results in sex cells (gametes), results in eggs and sperm, purpose is for creating new individuals (eventually), each daughter cell is different, has 2 separate division stages
- This is because meiosis occurs in gametes and is used in reproduction.
Both: Chromosomes need to replicate before the whole process begins, a form of reproduction
- This is because both are reproducing (they are dividing) and DNA must be replicated so each daughter cell has it.
Answer:
We know that the color of jellyfish is controlled by codominance inheritance pattern and yellow Y and blue B are two alleles and in case of heterozygous the goober or green color occurs then,
If Yellow jellyfish is crossed with goober, that is, YY X YB.
the punnett square will be -
Y Y
Y YY YY
B YB YB
The possible genotype of offspring will be YY, and YB and therefore, the possible phenotype of offspring will be Yellow, and Green. The Percentage of yellow offspring will be 50% as two out of four are dominant for Y allele and two heterozygous conditions that is 50 % and as there are two copies B alleles are not present so zero percent of blue color.
