where photosynthesis takes place
Iron rich deposits that formed about 2 billion years ago have red layers. Layers formed before then were not red. The red layers formed when oxygen made during photosynthesis reacted with iron molecules in the ocean. The oxidized iron formed layers of sedimentary rock
. Which BEST summarizes this phenomenon?
A. The lithosphere changed the atmosphere. B. The hydrosphere change the atmosphere.
C. The atmosphere change the biosphere.
D. The biosphere change the lithosphere
Answer:
D. The biosphere change the lithosphere
Explanation:
The red formed due to oxygen which is produced by plants in the process of photosynthesis. This oxygen then reacted with iron atom and formed oxidized iron layers of sedimentary rock. So here plants are responsible for the formation of these layers and we considered plants as part of biosphere so we can say that biosphere is responsible for the change of lithosphere.
Answer:
D. The biosphere change the lithosphere

It increases the temperature of the reaction.
Explanation:
Enzymes increase the speed of the chemical reaction. The reaction usually gets faster when the temperature is high. As a result, I think that this is the best choice of all.
Explain why the passenger pigeon,which was once the most abundant bird in north America,disappeared completely.
Answer with Explanation:
The "passenger pigeon" used to be North America's most popular bird. Their population even reached 3 billion (or even more). They always traveled together. Their decline in number was noted in the 19th century. People became interested in hunting them for food because they were relatively cheap and tasty . They were also a great source of protein. It was easy to hunt them down although they could fly very fast because their flocks were huge in number. Some people killed them because they didn't want the birds ruining their crops. Their nesting grounds were also disturbed, which ultimately drove them away from the forests. People were overkilling them, and this sped up with the advancement of technology. The number of pigeons killed outnumbered the newborn pigeons, and after decades of hunting them down, their number dwindled with the last one passing away in 1914.

How many triple codons would you need to make the 6 chain protein?
Answer:
Some amino acids are encoded by more than one codon, inasmuch as there are 64 possible base triplets and only 20 amino acids. In fact, 61 of the 64 possible triplets specify particular amino acids and 3 triplets (called stop codons) designate the termination of translation.
How might the fennec fox's population suddenly Increase? How might this affect the ecosystem?
Answer:
If rabbits population (prey of fennec foxes) suddenly increase as well. The other prey of the fennec foxes would shrink in population because there would be more fennec foxes to eat them. This would at some point even out and the ecosystem would go back to normal.

how sexual reproduction plays its role in avoiding genetic monotomy
Answer:
Abstract
The relative contributions of sexual and asexual reproduction to the genetic structure of populations can be difficult to determine for fungi that use a mixture of both types of propagation. Nuclear RFLPs and DNA fingerprints were used to make indirect and direct measures of departures from random mating in a population of the plant pathogenic fungus Mycosphaerella graminicola during the course of an epidemic cycle. DNA fingerprints resolved 617 different genotypes among 673 isolates sampled from a single field over a 3-month period. Only 7% of the isolates represented asexual clones that were found more than once in the sample. The most common clone was found four times. Genotypic diversity averaged 85% of its maximum possible value during the course of the epidemic. Analyses of multilocus structure showed that allelic distributions among RFLP loci were independent. Pairwise comparisons between individual RFLP loci showed that the majority of alleles at these loci were in gametic equilibrium. Though this fungus has the capacity for a significant level of asexual reproduction, each analysis suggested that M. graminicola populations maintain a genetic structure more consistent with random-mating over the course of an epidemic cycle.

What are the 3 common characteristics of planets? Describe one of the characteristics of one of the planets in our solar system
Answer:
The solar system is host to two broad categories of planets. The four closest to the sun — Mercury, Venus, Earth and Mars — are the terrestrial planets. They have rocky surfaces enclosed by relatively shallow atmospheres. The gas and ice giants — Jupiter, Saturn, Uranus and Neptune — are outliers. They are much larger than the terrestrial planets, but their cores are small and icy. Most of their size is formed by a combination of gases that become denser and hotter as you get closer to the core. Scientists count eight planets overall. Pluto was reclassified as a dwarf planet in 2006.

mitochondria.
.
Most ATP is produced during glycolysis and the
Krebs cycle.
d The Krebs cycle occurs directly after glycolysis.
Answer: a. Glucose is broken down to pyruvate.
b. Respiration requiring oxygen occurs in the mitochondria.
Explanation:
Cellular respiration can be defined as the process in which oxidation of food occurs in the mitochondria and energy is released as ATP. The glucose which is six carbon molecule is most common substrate for oxidation and it is converted into pyruvate which is a three carbon molecule. This is occurs in aerobic cellular respiration. During cellular respiration 30+ ATP molecules are produced which is comparatively more than glycolysis and Kreb's cycle.

megakaryocytes are huge cells found in red bone marrow that extend long tendrils into blood sinusoids. The flow of blood breaks off small portions of those tendrils creating the formed element known as
Answer:
Platelet
Explanation:
In 1906 James Homer Wright established that platelets, seen as hyaline bodies or vacuoles, are formed in the cytoplasm of megakaryocytes in the bone marrow, which then disintegrate and pass as platelets into the circulation. Megakaryocytes are cells of the myeloid lineage. They originate platelets (or thrombocytes) by cleaving parts of their enormous cytoplasm directly into a sinusoid vessel. The function of platelets is to form thrombi to prevent blood loss in small blood vessel ruptures.
When you exercise or sunbathe, you sweat. that sweat eventually evaporates. Why does this occur
Answer:
The sweat leaves your skin through tiny holes called pores. When the sweat hits the air, the air makes it evaporate (this means it turns from a liquid to a vapor). As the sweat evaporates off your skin, you cool down.

Why does the body produce more urine on a cold day rather than a hot day if the same amount of
water is consumed?
Explanation:
During summer when the surrounding temperature is high, we lose water in the form of sweat, direct evaporation considerably. Hence kidneys retain water for maintaining fluidity of the blood and less urine is formed.
But during winter, the surrounding temperature will be very low. There will not be any sweating, no evaporation losses. Moreover to keep the body temperature constant, the blood capillaries in the skin get constricted and the blood pressure is increased. The result is that our body gets warmed up. In order to maintain the blood pressure normal, the excess water along with the wastes is excreted mostly in the form of urine. This is the reason for more urine out put and frequent urination under very cool conditions and in winter.
