Higher atmospheric pressure and stronger greenhouse effect leads to the presence of water on the surface of Mars planet.

Mars must have had higher atmospheric pressure as well as stronger greenhouse effect than Mars today which is responsible for the presence of water in liquid form on its surface but when the disturbance or change occurs in the atmospheric pressure as well as greenhouse effect of the Mars planet.

The water that was present on the surface vaporized and removed from the planet so we can conclude that higher atmospheric pressure and stronger greenhouse effect leads to the presence of water on the surface of Mars planet.

Most deer mouse populations inhabit regions with dark soils. These deer mice have dark brown fur. Populations of deer mice found
mixas84 [53]

Answer:

Tan fur helps the mice protect themselves from predators

Explanation:

The entrenchment of this phenotype in the population is powered by natural selection pressures. The mice with fur color that enable them to camouflage with their environment are predated less than mice with other fur colors. These tan mice are therefore more likely to survive and pass their genes to the next generation. Through successive generations, the allelic frequency for the tan fur color increases until it is the dominant allele in the population.

En las clases de ciencias estan hablando de varios movimientos que presentan las plantas debido a estimulos de ambiente, Pedro p
marin [14]

Answer:

En resultados

Explanation:

El experimento se basa en analizar el movimiento de la planta en respuesta a la luz solar, desde distintas posiciones:

  • planta parada
  • planta semiacostada
  • planta acostada

Durante su experimento, Pedro debe ir registrando los movimientos que observa en las distintas plantas a medida que recibe la luz del sol. El registro de dichos movimientos ante el estímulo forma parte de los resultados.

- Objetivo o propósito del trabajo: analizar la influencia de la luz solar como estimulo para generar un movimiento en plantas desde distintas posiciones.

- Procedimiento: Ubicación de plantas en distintas posiciones y bajo las mismas condiciones ambientales. Exposición de todas las plantas a la misma cantidad de radiación solar. Observación del movimiento durante un periodo de tiempo determinado.

- Resultados: Registro del movimiento de cada planta en cada posición durante el periodo de tiempo que fueron expuestas a radiación. En esta instancia de vuelca en tablas o gráficos, o se describe qué fué lo que se observó durante el experimento. Cuál fue la respuesta de cada una de las plantas.

- Conclusión: Relación entre lo esperado y lo observado. Comparación con otros trabajos similares.

Calculate the number of neutrons in an atom of an element that has a mass number of 98 and an atomic number of 42
olya-2409 [2.1K]
There are 56 neutrons. To find them, you just have to subtract the atomic number with the atomic mass. If you dont know, the atomic number is the number of protons (and electrons) in an atom. The atomic mass is the number of both the protons and neutrons. Of you subtract the atomic number, you get protons.

9) Identify the FALSE statement regarding sensory receptor cells. A) A graded potential is referred to as a receptor potential.
rjkz [21]

Answer:

<u> C) Each type of sensory receptor responds only to the stimulus that defines the receptor</u>

<u></u>

Explanation:

Neurons,  specialized cells within the nervous system. These help with coordinated movement ad communication within the body through the transmission of electrical signals.

Sensory receptors are highly specialized neurons. These are able to detect various chemical and physical stimuli, and are classified by their ability to detect certain stimuli such as:

  • photoreceptors
  • mechanoreceptors
  • chemoreceptors
  • thermoreceptors

Sensory receptors respond to certain intensities of stimuli, instead of one specific stimulus. e.g. Mechanoreceptors within the skin can respond to pressure changes due to touch, but may also detect sound due to specific vibrations.

Cloned DNA can be store for use in vectors in a ________.
tankabanditka [31]
Plasmid. A plasmid is a small circular DNA presents in bacterial cells. It is used as a cloning vector for DNA. The cloned DNA and the plasmid are treated with a restrriction enzyme. The enzyme will make cleaveges in the same portions of the two DNA. The plasmid is then allowed to be replicated inside the bacterial cell.
