Answer
Most of these techniques, including microarray analysis and reverse transcription polymerase chain reaction (RT-PCR), work by measuring mRNA levels. However, researchers can also analyze gene expression by directly measuring protein levels with a technique known as a Western blot.
Answer;
Seedless plant.
The fossil of a plant reveals that it produced spores that were used for reproduction. It was a seedless plant.
Explanation;
-Seedless vascular plants are plants such as fern and horsetails, liverworts, mosses; which contain vascular tissues, but do not produce flowers or seed.
-These plants reproduce using haploid , unicellular spores instead of seeds.
-These plants have life cycles with two distinct stages; one in which spores are produced and one in which sex cells are produced.
When selecting a vitamin-mineral supplement, one should be careful to choose one that has nutrient levels that are less or equal to the RDA, but not exceeding it. The supplement is designed to provide a variety of nutrients that are also found in food. They are often called multivitamins and come in form of chewable tablets, pills, liquids and powders.
If a given moth population is at Hardy-Weinberg Equilibrium, we can conclude that the changes in the allele frequency of the population over time is constant. This means that in the absence of evolutionary influences, allele or genotype frequencies remain constant from one generation to the next or so on.
1- chloroplasts is eukaryotes cell
2- chloroplasts
3- Chloroplasts are organelles found in plant cells and eukaryotic algae that conduct photosynthesis. Chloroplasts absorb sunlight and use it in conjunction with water and carbon dioxide gas to produce food for the plant.
4- 100 chloroplasts are in a plants cell
5- a Cell that don’t have chloroplasts can’t perform photosynthetic example mushroom don’t have chloroplasts they can’t make their own food they can only store their food.
6- the eye because Chloroplast captures the energy from the sunlight to produce food and energy. This is only found in plant cells. The equivalent in the human body is the eye because it absorbs energy.
