Mammals really spread and diversified during the Cenozoic era. So, the correct option is D.
What was Cenozoic era?The Cenozoic Era is defined as the third of the major eras in Earth's history that began about 66 million years ago and extends to the present. This epoch was the interval of time during which the continents assumed their modern configurations and geographic positions during which the Earth's flora and fauna evolved towards the present.
The Cenozoic Era is called the "Age of the Mammals", while the typical landscapes of North America began to develop during the Cenozoic. Birds and mammals rose to prominence after the extinction of giant reptiles.
Thus, Mammals really spread and diversified during the Cenozoic era. So, the correct option is D.

The human hands and feet have similar types and numbers of bones. However, hands and feet are very different in their appearance. What physical differences do you notice between the hands and feet? How might these differences relate to differences in the function of these body parts? Would you expect other primates to have hands and feet differently like this? Why or why not?
Answer:
Hands have a larger range of dexterity compared to feet. Longer tendins and stronger grip strength, they are made for more intrucite tasks such as making and using tools. Feet have a larger surface area, made for holding large amount of weight, shorter bones and tendins allow for easy acceleration and no extra flesh to get in the way. Other more primitive species will not have the feet we have due to evolution. They simply do not have the evolved sense of brain pwer hians haev in order to make tools. So they have more need for speed, grip exc. in feet to escape pradators and live day to day. Where on the other hand humans do not.
Explanation:
The metatarsals that can be found in the foot are larger than the metacarpal bones that are in the hands.
It should also be noted that the phalanges of the hand are larger than that of the foot. The way that the metacarpal of the thumb is built is vital for mobility and movement.
Primates have hands and feet that are different from that of humans because they use their hands and feet for grasping. They also have strong clavicles and flexible shoulder joints. This enables them to climb and grasp things firmly.

1. You have set up a cell-free transcription system in a test tube. By mixing DNA, RNA polymerase, sigma factors, ribonucleotides and other essential substances you are able to make mRNAs identical to those made under a variety of conditions in the cells from which these components were isolated. What would happen if you were able to remove the sigma factor first added to the tube and replace it with another sigma factor
Answer:
Different messenger RNAs (mRNAs) would have been produced
Explanation:
Sigma factors are protein subunits that form bacterial RNA polymerases and they are responsible to initiate RNA synthesis. The number of sigma factors is variable between different bacterial species. For example, Escherichia coli contains seven sigma factors, while Bacillus subtilis has at least 17 sigma factors, which control the transcription of different genes. These factors determine the specificity of the RNA polymerase to the target gene promoter regions and then control transcription initiation.

What is the relationship between a zebra and a lion
Answer:
The Zebra's The Lion's Dinner
Explanation:
I don't really need to explain this much I don't think. The Zebra's the prey, and the Lion is the hunter. Thanks! Have a good day!
Answer:
the relationship between a zebra and a lion would be prey(zebra) and predator(lion).
Explanation:
the zebra is the prey because it is an herbivore and does not hunt other animals. the lion is the predator because it is an carnivore meaning it hunts other animals(usually weaker than said predator).
What characteristics do you think could be used to classify different kinds of single-celled organisms? Write your ideas here
Answer: flagellum, a plasma membrane and organelles.
Explanation: In that sense, it can be difficult to find traits that they all share. Still, Project Oceanography at the University of San Francisco indicates that single-celled organisms have a number of common characteristics, including the presence of flagellum, a plasma membrane and organelles.
Flagellum, a plasma membrane and organelles classify different kinds of single celled organism and prokaryotic organism.
What are the different features of prokaryotic cell ?Prokaryotic cell are single celled organism, do not have membrane bound organelles and its size varies from 0.2 μm – 2.0 μm.
Here the Cell wall is present but True Nucleus is absent, the cell wall is mainly involve in photosynthesis and provide protection to cell, the ribosomes are Smaller in size having 70s type and spherical in shape.
Circular DNA is present as genetic material in prokaryotes, Mitochondria is absent in prokaryotes, the reproduction usually occur by binary fission and some times it occurs through conjugation.

A. Write two sentences explaining how carbon returns from the air to the ground.
Answer:
In the atmosphere, carbon is attached to oxygen in a gas which is called carbon dioxide and through the the process of photosynthesis, it is pulled from the air to produce food made from carbon for plant growth. And through food chains, the animals that eat plants get that carbon and so do the animals that eat those animals.
When an animal dies, their bodies as well as wood and leaves decaying brings the carbon into the ground.

Con ayuda de un microscopio se observa una bacteria en el agua transcurridas (2) se miran muchas bacterias . Que ocurrio alli ,que tpo de reproducccion sucedio meiosis o mitosis
Answer:
Ninguna de las dos. No ocurre ni mitosis ni meiosis.
Probablemente haya ocurrido fisión binaria/bipartición.
Explanation:
En este caso estamos hablando de bacterias, organismos unicelulares procariotas. Estos tienen una forma de reproducción asexual denominado fisión binaria. Los eucariotas por su parte pasan por periodos de división celular implicada en el crecimiento denominado mitosis, y división celular implicada en reproducción sexual, denominada meiosis.
La fisión binaria, también conocida como bipartición, si bien muy parecida a la mitosis en algunos aspectos, es la forma de reproducción de las bacterias.
Ambas, mitosis y fisión binaria, implican un duplicado de material genético. El ADN se duplica y una copia va a cada célula hija. Lo mismo sucede con el resto del contenido celular. Finalmente ocurre citocinesis. Sin embargo, a diferencia de la bipartición, la mitosis requiere de mecanismos mucho mas complejos de duplicación celular e involucra también a la cariocinesis, ausente en bacterias.
La fisión binaria ocurre muy rápidamente, en un breve período de tiempo puede hallarse una diferencia considerable en la cantidad de células presentes en un sustrato, producto de esta división. Es por esto que el crecimiento que exhiben las bacterias como población, sigue un modelo exponencial.

i am sorry if it is wrong
The trampling of plants by animals is not an example of a biotic factor, while animals and plants are examples of biotic factors. Hence, it is false.
What are biotic factors?A living thing that alters its surroundings is referred to as a biotic factor. Examples of organisms found in a freshwater habitat include algae, fish, amphibians, and aquatic plants. A particular ecosystem is the result of the interaction of biotic and abiotic components.
A living entity that influences another organism in its ecosystem is referred to as a biotic factor. Examples include the plants and animals the organism eats as food and the animals it consumes.
The trampling of plants by animals is not a biotic factor while living organisms and plants are biotic factors. Hence, it is false.
