Blue-green algae affect freshwater, and it has a direct correlation to agricultural and urban runoff.
The heavy rains last spring most likely caused Lake Okeechobee to discharge water containing blue-green algae into rivers and canals. The bright green sludge oozed onto docks, dams and rivers and through tributaries into the ocean.
Blue-green algae (cyanobacteria) are a group of prokaryotic, autotrophic microorganisms that contain the photosynthetic pigments (chlorophyll and phycocyanin), Therefore, the DNA shows bacteria
Bacteria is the correct answer
Answer: Cellular organization.
Reproduction.
Metabolism.
Homeostasis.
Heredity.
Response to stimuli.
Growth and development.
Adaptation through evolution.
A new antibiotic is produced that inhibits the synthesis of acetyl-CoA and the electron transport chain in bacteria that normally require oxygen. For each glucose molecule that is metabolized, how many fewer ATP molecules will be produced?
38
4
36
34
2
Answer:
36
Explanation:
Glycolysis of cellular respiration produces only two molecules of ATP per glucose molecule. Kreb's cycle also forms 2 ATP molecules per glucose by substrate-level phosphorylation. However, oxidation of NADH and FADH2 by electron transport chain produces as many as 34 ATP molecules (almost 3 ATP per NADH and 2 ATP per FADH2). This obtains a total of 38 ATP molecules per glucose by the complete pathway of aerobic cellular respiration.
In presence of an antibiotic that inhibits Kreb's cycle and ETC of cellular respiration, a cell would produce only 2 ATP molecules (by glycolysis) per glucose. Therefore, it would obtain 38-2= 36 lesser ATP molecules.
Answer:
I. The nuclear membrane breaks up.
II. Sister chromatids condense.
III. Sister chromatids align on the metaphase plate.
IV. The cleavage furrow forms.
V. Sister chromatids separate.
Explanation:
Mitosis is divided into 5 stages:
- Prophase
- Metaphase
- Anaphase
- Telophase
- Cytokinesis
The prophase stage is marked by two main events
- <em>Dissolution or breakage of nuclear membrane</em>
- <em>Condensation of genetic materials</em>
Metaphase is marked by
- <em>Alignment of chromosomes (made up of two sister chromatids) on the metaphase plate</em>
- <em>Attachment of spindles to aligned chromosomes at the centromere</em>
Anaphase is marked by
- <em>Initiation of cleavage furrow formation</em>
- <em>Shortening of spindle fibers results in the separation of sister chromatids</em>
- <em>Sister chromatids begin migrating to opposite poles</em>
Telophase
- <em>Chromatids completes their migration to the poles</em>
Cytokinesis
- <em>Nuclear membrane reforms</em>
- <em>Sister chromatids decondense</em>
- <em>Cytoplasm divides</em>
Answer: The amino acid 6 will form the hydrogen bond with the backbone of amino acid 2
Explanation:
- The alpha helix is the common motif of protein secondary structure in which amino acids wind up to form a right hand-helix.
- In α-helix hydrogen bond form between carbonyl group of one amino acid and N-H group of four amino acid down the chain (that would be the 5th amino acid).
- These patterns of hydrogen bonding would make the helical patterns of polypeptide, each turn containing 3.6 amino acids.
