Answer:
A. Nature exists as a resource that should be preserved for future generations.
Explanation:
Deep ecology movement is an idea that all living organisms on the earth have right to live with their basic moral values. All organisms must be respected irrespective of their size, shape or other physical features. Natural resources are scarce and so they should not be wasted and must be saved for future generations.
earth science: fossils question pls help
Answer:
Layers A and B show cratures that would most likely be found in the ocean (they have fins, etc.) then the next layer has no animals and after that the animals beofre are no longer seen. This must mean that the creatures went exticnt due to an envoirmental issues, in this case its a volcanic explosion (as seen in the key in the corner were the shaded area is indicated as volacanic ash). In layer D, we see a plant, this shows us that the envoirment is now land. After that is another layer of volcanic ash and then F. were we see the previous plants and animlas with the inclusion of 'bird'. I think this means that the envoirment has more greenier wether from the nutrients rich soil (due to the volcanic ash) or another factor.

Identify one major greenhouse gas that contributes to global warming.
Answer:
Indeed, carbon dioxide, a byproduct of fossil fuel combustion, is the principal greenhouse gas contributing to global warming. However, other greenhouse gases including methane, nitrous oxide, and a number of industrial-process gases also are important contributors to climate change.

What are the necessary conditions for autotrophic nutrition and what are its byproduct ?
➜ The conditions necessary for autotrophic nutrition are sunlight, chlorophyll, carbon dioxide (CO2) and water (H2O).
The byproducts of autotrophic nutrition are water and oxygen.
Answer:
Carbon dioxide, water, chlorophyll pigment, and sunlight are the necessary conditions required for autotrophic nutrition. Carbohydrates (food) and O2 are the by-products of photosynthesis.

Heparin, a highly negatively charged glycosaminoglycan, is used clinically as an anticoagulant. It acts by binding several plasma proteins, including antithrombin III, an inhibitor of blood clotting. The 1:1 binding of heparin to antithrombin III seems to cause a conformational change in the protein that greatly increases its ability to inhibit clotting. What amino acid residues of antithrombin III are likely to interact with heparin
Answer:
Positively charged amino acids
Explanation:
Heparin is an acid polysaccharide that has a strong negative charge due to the sulfate groups on its glucosamine residues. This negative charge confers to heparin anticoagulant activity. The negatively charged groups in the heparin molecule can interact with positively charged (basic) residues, such as arginine (Arg) and lysine (Lys) of plasma proteins. For example, it has been shown that lysine amino acid residues of antithrombin III may be involved in the binding with heparin.
PLEASE HELP!!! I WILL GIVE BRAINLIESTA dichotomous key is a helpful identification and classification tool. Scientist also use genetics (DNA) to classify organisms? Now that we know a little more about dichotomous keys, which is a more accurate way to classify organisms? Explain.
Answer:
DNA contains specific physical characteristics unique to the person to which the DNA belongs. This information helps classify organisms, by type. All sorts of traits are used to classify organisms, but DNA is the best way.

Which natural resources did early humans need for basic survival?
A. Early humans needed tools made from rocks.
B. Early humans needed material to make boats with sails to get from place to place.
C. Early humans needed water, plants and animals for food.
D. Early humans needed fresh water and clean air.
Answer:
i think C. Early humans needed water, plants and animals for food.
Explanation:
Water, plants and animals are the basic needs for survival other then tools made out of rocks, even though A could be the right answer too.
What causes the expression of a recessive trait?
A) two dominant factors
B) one dominant and one recessive factor
C) two recessive factors
D) one dominant gene
Answer:
C two recessive since it gives a high chance of a recessive trait
Explanation:
Answer: C. Two recessive factors
Explanation: Good luck! :D
Let's use red hair for example - r
And we'll say that brown hair is dominant - R
You won't get red hair from RxR, the gene isn't in the punnet square. (Not A.)
Rxr would be always be Brown hair and they carry the red hair gene. (Not B.)
The dominant gene is the opposite of the recessive trait. (Not C.)

What is believed to be the main cause of most mass extinctions throughout geological history?
Answer:
was caused by global warming that left ocean animals unable to breathe. The largest extinction in Earth's history marked the end of the Permian period, some 252 million years ago
Explanation:
True/False: The law of conservation of energy applies to the cycle of photosynthesis and cellular respiration.
Answer:
True,Every chemical reaction obeys the law of conservation of mass.
Phage are viruses that must infect bacteria to reproduce. Viral genomes do not contain all the genes needed to produce all proteins necessary for DNA replication, RNA transcription, and protein translation; instead the viruses force bacterial proteins and enzymes to express phage genes instead of bacterial genes.
Phage are very adaptable, and their behavior depends on whether conditions are favorable or unfavorable for making more phage.
When bacteria are plentiful (favorable conditions), viral DNA within the bacteria remains separate from the bacterial chromosome, and the virus forces the bacteria to make more virus. When the amount of virus becomes too much for the cell to hold, the membrane ruptures, and viruses are released to infect surrounding bacteria. This is known as the lytic cycle.
When bacteria are scarce (unfavorable conditions), the viral DNA within the bacteria becomes integrated into the bacterial chromosome. The bacteria survive and are still able to reproduce; viral DNA is transmitted to daughter cells when the bacteria reproduces. This is known as the lysogenic cycle.
As you just read, phage depend on bacteria to reproduce. Phage can be maintained by infecting a culture of bacteria with a strain of phage, and then plating the bacteria on an agar plate to grow.
Suppose that you isolate two mutant strains of phage - one strain cannot enter the lytic cycle and the other strain cannot enter the lysogenic cycle. You also grow wild-type phage as a control. You see three different phenotypes:
A plate with no missing bacteria- the lawn of bacteria is intact
A plate with spots/circles (called plaques) where there are absolutely no bacteria in the circles
A plate with spots/circles (called plaques) where there are some bacteria in the center of the circles.
Based on what you know about what happens in each cycle, match the plating results with the identity of the strain.
Drag each plate into the correct category.
Answer:
A plate with no missing bacteria- the lawn of bacteria is intact----strain with lysogenic cycle.
A plate with spots/circles (called plaques) where there are absolutely no bacteria in the circles---- lytic cycle
A plate with spots/circles (called plaques) where there are some bacteria in the center of the circles----- wild type phage.
Explanation:
The strain which cannot enter the lytic cycle having no missing bacteria on the plate because the virus remains inside the bacterial cell while on the other hand, the other strain that cannot enter the lysogenic cycle having no bacteria on the circle due to infection of virus spreads throughout the cells and no bacterial cell remains uninfected. One plate having some bacteria and some space having no bacteria due to virus of wild type that shows both cycles.
