Answer:

How does CO₂ relate to whales?

Whales take in CO₂ during their lives and thereby reduce the amount of it in the waters.

What is the effect of this on the different organisms living in the water?

Rising CO₂ levels make the water more acidic, which harms animals who need a certain pH to survive. It also limits coral reef growth.

Answer:

Tofu and soy oil come from soy bean plants that are grown on farms. Many farmers grow soy beans as cash crops that they can send to places such as tofu processing plants. Soybean plants are legumes. Legumes have bacteria on nodules which are on the roots of the plant. The bacteria on the nodules takes nitrogen from the air and fixes it into the soil, so that other plants that require nitrogen can use it as well.

This nitrogen cycle that was breifly discussed above is used in what farmers call a crop rotation. Farmers use soybeans and other legumes in roatations with grass crops such as corn or wheat. Grass crops are unable to take their own nitrogen from the air so they either need the nitrogen in the soil that the legumes provide for them in a crop rotation or they need a chemical fertilizer containing nitrogen. Many farmers choose to use both. Most farmers use a two or four year rotation on their fields. In a two year rotation a farmer will alternate a year of a legume such as soybeans and a year of a grass crop such as corn. In a four year rotation a farmer will alternate back and forth between legumes and grass crops just as in a two year rotation, but instead he will use four differnt crops. For example, a farmer may plant a rotation of soybeans, corn, alfalfa (a legume), then wheat (a grass).

Can you identify the supergroups to which these protists belong?

uranmaximum [27]

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.

Transcribe T-A-C-C-G-T ot DNA into mRNA

romanna [79]

The answer will be A-U-G-G-A
Transcription is the process by which DNA molecule is used as a primer to generate and mRNA, catalyzed by the enzyme RNA polymerase. The process takes place in the nucleus, after which the mRNA is taken to the cytoplasm for translation. One of the differences between RNA and DNA is the base thyamine and base Uracil, RNA contains base Uracil instead of thyamine.
