Al examinar la aleta de un pez primitivo, los científicos encontraron similitudes entre su estructura ósea y la de los reptiles, las aves y los mamíferos modernos. ¿Que tipos de evidencias describe este caso?
Answer:
evidencia de un antepasado común entre grupos de vertebrados (gnatóstomos)
Explanation:
En el estudio comparativo arriba descripto, se encontraron semejanzas que provienen de un antepasados común. Este tipo de evidencia se conoce como homología, es decir, semejanza entre diferentes grupos de organismos causada por un mismo origen evolutivo. Los gnatóstomos (vertebrados con mandíbula) conforman un grupo de organismos el cual incluye peces óseos, peces cartilaginosos, anfibios, reptiles, aves y mamíferos. En este caso, las extremidades del grupo de los gnatóstomos (las cuales tienen como origen común la aleta de un pez primitivo) son similares porque son estructuras homólogas.
A student outlined the following steps of the lytic cycle of bacteriophage infection of bacterial cells:
1. Virus lands on host cell.
2. Virus injects the capsid containing its DNA into the cell.
3. Viral DNA is used by bacteria to make vinis parts.
4. New viruses are assembled in the bacterial cell.
In what phase of meiosis is DNA replicated?
Answer:
During prophase I, the chromosomes condense and become visible inside the nucleus. Because each chromosome was duplicated during the S phase that occurred just before prophase I, each now consists of two sister chromatids joined at the centromere.

Athletes train at high altitude, thereby increasing the number of red blood cells, to improve their
performance. How might an increase in the number of red blood cells improve an athletes
performance?
Answer:
Preparing at moderate height may improve ocean level execution in perseverance competitors. This was noted after the 1968 Olympics in Mexico City (7600 feet) when a few competitors found an improvement in their presentation after re-visitation of ocean level. Be that as it may, different competitors didn't see any distinction in execution. Studies have indicated improved high-impact power in sprinters who prepared at 6,000 feet for 10 days at that point performed at low elevation. Lower oxygen levels at elevation invigorate EPO prompting expanded red platelets or hematocrit. This viably permits more oxygen to be conveyed to the tissues. Basically, this is blood doping the regular way.
Late examinations do propose profits by 'preparing low' and 'dozing high'. This incorporates hypoxic tents that numerous competitors are presently utilizing. These tents have a generator that extricates oxygen from the air, establishing a moderate height climate. Competitors at that point rest/relax in them for a few hours per day. This invigorates erythropoietin, subsequently expanding the hematocrit (red platelet tally). Without a doubt the 'live high, train low' idea may permit the best blend. One examination separated 39 contenders into three preparing gatherings; living and preparing adrift level, living at height and preparing adrift level, living at elevation and preparing at height. The two gatherings who inhabited height had expanded red platelets and VO2max, however just the gathering who lived high and prepared adrift level had improved race times. One clarification for this is that the live high, train low gathering can prepare more diligently and better use their blood's oxygen conveying limit. As a result of expanded red cell creation, all competitors preparing as well as resting at elevation should ensure they have proper iron stores and nourishment. This is particularly valid for ladies, as they will in general have lower iron stores because of occasional loss of blood through monthly cycle.

90% H2O 10% Solute The solution is: hypertonic / hypotonic / isotonic Water will: not move / move into the cell / move out of the cell
Answer:
Hypotonic / moves into the cell.
Explanation:
Hope you have a nice evening.
The solution is hypotonic. Water will move into the cell.
What is hypotonic solution?A hypotonic solution is one where the concentration of solutes outside the cell is lower than the concentration inside the cell. In this case, the solution is composed of 90% water and 10% solute, which is a lower concentration of solutes than inside the cell.
As a result, water will move into the cell in order to balance the concentration of solutes and maintain homeostasis. This can cause the cell to swell and may even lead to lysis if the cell is unable to handle the increased volume.

why is endosymbiotic theory not a law in science?
Answer:
Many scientists were skeptical of the endosymbiotic hypothesis because it didn't seem to fit into the theory of evolution as it was understood then. Between 1900 and 1950, biologists made many key discoveries in the field of genetics by focusing on small, random changes in DNA — mutations — that occur when a cell reproduces.
Explanation:
How have plants evolved?
Give at least 5 examples.
Answer:
Over time, plants had to evolve from living in water to living on land. In early plants, a waxy layer called a cuticle evolved to help seal water in the plant and prevent water loss. ... To allow the plant to retain water and exchange gases, small pores (holes) in the leaves called stomata also evolved (Figure below)
Explanation:
1 DNA evidence suggests that the first eukaryotes (green plants) evolved from prokaryotes (through endosymbiotic events) between 2500 and 1000 million years ago. ... Cyanobacteria have a close evolutionary relationship with eukaryotes. They have the same photosynthetic pigments as the chloroplasts of algae and land plants.
2Plants adapt their growth, including key steps in their life cycle such as germination and flowering, to take advantage of environmental conditions. ... All land plants evolved from an aquatic ancestor, and it was after colonisation of the land that the gibberellin mechanism evolved.
3 700 million years ago
The researchers found that land plants had evolved on Earth by about 700 million years ago and land fungi by about 1,300 million years ago — much earlier than previous estimates of around 480 million years ago, which were based on the earliest fossils of those organisms.
4 The earliest trees were tree ferns, horsetails and lycophytes, which grew in forests in the Carboniferous period. The first tree may have been Wattieza, fossils of which have been found in New York State in 2007 dating back to the Middle Devonian (about 385 million years ago).
5 Plants adapt to their environment from necessity. Plants may also adapt by growing lower and closer to the ground to shield themselves from wind and cold. Desert environments may have some of the following adaptations, these help the plant to conserve food, energy and water and still be able to reproduce effectively.
