Answer:
The correct answer is - contains many genes for transcription factors that are present in cnidarians and bilaterian animals.
Explanation:
Placozoans are the simplest known metazoan organism known on earth and found in warm water and all over the globe. Placozoans are very small approximately 2 to 3 mm.
These are basal forms of marine free-living multicellular organisms. In the molecular studies, it is found that they have similar genes that are present in cnidarians and bilaterian animals for transcription factors.
Answer:
B. urbanization
Explanation:
In urbanizing stage, death rate quickly declined because of the improvements in agricultural aspect which goes down to food supplies, health care delivery, medicine improvements, and even the investments in sanitation and infrastructure which contributes to the increasing life expectancy of the people and lesser diseases which cause deaths. Though birth rates remain almost the same, but young population continues to grow because of the low death rate.
The answer is D. Chromosomes contain genes, and genes are made of DNA
Answer:
See below
Explanation:
Protists fall into the category of eukaryotes. They are diverse in nature and typically are found to be single celled organisms containing very organized structures.They are classified based on what is their source of nutrition.
<u>Autotrophic</u> - capable of photosynthesis to produce their own food, so an environment where sunlight, CO2 and water is available.
<u>Heterotrophic</u> - feed on other organisms
, an environment where prey is plenty and very limited or no access to sunlight.
<u>Mixotrophic</u> - a combination of the above two, an environment with all of the aforementioned factors present.
