Protists and Supergroups

Diatoms – SAR - Stramenopila

Foraminiferans – SAR - Rhizaria

Plasmodial slime molds - Unikonta - Amoebazoans

Trichomonas vaginalis - Excavata - Parabasalids

Giardia intestinalis - Excavata - Diplomonads

Dinoflagellates - SAR - Alveolata

Green algae - Archaeplastida- Chlorophytes

Brown algae - SAR-Stramenopila

Explanation:

Protists are the simplest eukaryotes. Due to their vast diversity of species, they are broadly divided into four supergroups or the clades. They are the Archaeplastida, Excavata, SAR clade, and Unikonta.

Archaeplastida: Interrelated with DNA sequence, cell structure, and endosymbiotic relationships. Divided into red algae, chlorophytes, charophyceans, and the plants. Eg, red algae, green algae, plants.

Excavata: Protists with cytoskeletal features like excavated grooves. This clade includes diplomonads, parabasalids, euglenozoans. Eg., Trichomonas and Giardia species

SAR: Protists interrelated with their DNA sequences and endosymbiotic relationships. Further divided into alveolata, stramenopila, and rhizaria. Eg., diatoms, dinoflagellates

Unikonta: Protists with flagella like structures, pseudopodia, genes fused together. Divided into amoebozoans and opisthokonts. These include slime molds, fungi, entamoebas, animals etc.

Harrizon [31]

(The question of who gets to benefit from these technologies), things like cas9 and rDNA will change everything. another most likely answer would be (The question of the long-term effects on consumers and the targeted species) BUT we know that it would be catastrophic if we used things like cas9 to change the evolutionary scale than to USE IT AS A CURE.

What are two main types of posttranscriptional modifications that take place in the mRNA of eukaryotes?The excision of the intro

Angelina_Jolie [31]

The correct answer is: The addition of a 7-mG cap at the 5' end of the transcript and the addition of a poly-A sequence at the 3' end of the message

These posttranscriptional processes are called:

• 5’ capping - It protects the mRNA from 5' degradation by exonucleases. Cap is also involved in ribosomal binding.

• Polyadenilation or addition of poly(A) tail – It also protects mRNA from degradation of 3’exonucleases. A long poly(A) tail can also increase translation.

Which of these is the study of interactions among organisms and their environment including its living and nonliving parts?

MakcuM [25]

Ecology is the study of interactions among organisms and their environment including its living and nonliving parts.

Answer: A. Ecology

Explanation:

Ecology is the investigation of how living beings associate with each other and with their physical condition. The conveyance and bounty of living beings on Earth is moulded by both biotic, living-life form related, and abiotic, nonliving or physical, factors.

Ecology is learned at numerous levels, including creature, populace, network, biological system, and biosphere. Water accessibility is a case of an abiotic, or nonliving, factor that can influence dispersion of creatures.

Accessibility of supplements given by different life forms is a case of a biotic, living-creature related, factor that can impact appropriation.

What are three disadvantages of making and using plastic?

AURORKA [14]

Plastic has many disadvantages, including environmental, choking and chemical hazards. Not only is plastic non-biodegradable, meaning it will not break down in landfills even after hundreds of years, it can also clog waterways and contaminate wildlife habitats. Plastic poses a danger to animals if they ingest it or become entangled. Additionally, chemicals are used to both produce and recycle plastic, a practice that poses environmental hazards as well. Recently under public scrutiny, a chemical called BPA is believed to cause hormonal problems in both males and females, especially those who are prepubescent. Lastly, young children may suffocate or choke on plastic.
