¿por que la toria de lamarck sobre el alargamiento del cuello de las jirafas por el esfuerzo continuado no pasara a sus descendientes? Porfa es ciencia y ambiente estoy en el peru

Answers

Answer 1

Respuesta: Los caracteres adquiridos no se transmiten genéticamente porque no modifican el ADN de los organismos

Explicación:

Jean-Baptiste Lamarck al igual que Charles Darwin, propuso una teoría sobre la evolución que explicaba cambios en los organismos a través del tiempo. La teoría de Lamarck se enfocaba en condiciones en el ambiente que propiciaban cambios en los organismos. Un ejemplo de esto son las jirafas, que de acurdo a Lamarck tenían cuellos largos debido al esfuerzo continuado para comer hojas de árboles altos. Esto significa que la característica de cuello largo era adquirido por las jirafas durante su vida y según Lamarck se transmitiría a sus descendientes.

Sin embargo, se ha comprobado que los caracteres adquiridos no modifican el ADN de los organismos, por ejemplo las cirugías estéticas no cambian el ADN de una persona y por esta razón no son transmitidos a sus descendientes. Por el contrario, en las poblaciones de organismos ciertas características prevalencen en el tiempo debido a la selección natural. Esto significa que el cuello de las jirafas es el resultado que el cuello largo sea una característica beneficiosa que ha prevalecido debido a la selección natural y no de características adquiridas que son transmitidas a descendientes.

1) To point the lens of a camera up or down is called:
A) Arc
B)Dolly
C)Pan
D)tilt

Answers

Answer:

D)

Explanation:

Tilting is a cinematographic technique in which the camera stays in a fixed position but rotates up/down in a vertical plane.[1] Tilting the camera results in a motion similar to someone raising or lowering their head to look up or down. It is distinguished from panning in which the camera is horizontally pivoted left or right. Pan and tilt can be used simultaneously.[2] In some situations the lens itself may be tilted with respect to the fixed camera body in order to generate greater depth of focus. [3][4]

The camera's tilt will change the position of the horizon, changing the amount of sky or ground that is seen.[5] Tilt downward is usually required for a high-angle shot and bird's-eye view while a tilt upward is for a low-angle shot and worm's-eye view. The vertical offset between subjects can reflect differences in power, with superior being above.

You want to complete conversion tracking setup on your business website with Google Ads. You've already implemented a global sitewide tag. Your next step is to create event tags, which must be placed in the correct section of your web pages to properly function. Where's the event tag implemented on a web page?

Answers

Answer:

The answer is "Between the website tags immediately after the global site tag".

Explanation:

The event tag is used to log clicks as well as perceptions for adverts, not creative things, or to define the inventive data, It may insert more parameters.  

These Tags are code binder clips, that are added to the site and then sent to respondents to obtain and send data. In this users could use tags to monitor scrolls, track suitable formulation, gather feedback, start generating heat maps, display advertising, to your website for all kinds of applications. The API also sends event details to Google Ads, show & Video 360, Campaign Manager, Search Anzeigen 360, and google docs that use the international site tag in the JS tag.

Communication network requires certain components such as sender, receive,data protocol and medium

telecommunications the message such as text , audio , video through electronic media in the from of electronic signals

The direction of communication from sender to receiver and vice versa

[tex] \huge \bold \blue{AnSweR}[/tex]

Communication is the act of giving, receiving, and sharing information -- in other words, talking or writing, and listening or reading. Good communicators listen carefully, speak or write clearly, and respect different opinions.

The transmission of information, as words, sounds, or images, usually over great distances, in the form of electromagnetic signals, as by telegraph, telephone, radio, or television.

The transmission model of communication describes communication as a one-way, linear process in which a sender encodes a message and transmits it through a channel to a receiver who decodes it.

Complete the body of the format_name function. This function receives the first_name and last_name parameters and then returns a properly formatted string. Specifically: If both the last_name and the first_name parameters are supplied, the function should return like so:

Answers

Answer:

Here is the Python program:

def format_name(first_name, last_name):  #function definition of format_name that takes first_name and last_name as parameters

   if first_name != '' and last_name != '':  #checks if first_name and last_name both are not equal to " "

       return ("Name: " + last_name + ", " + first_name)  #returns first name and last_name in format: "Name: last_name, first_name"

   elif first_name != '' or last_name != '':  #checks if either of the first_name or last_name is not equal to " "

       return ("Name: " + last_name + first_name)  #returns first name and last_name in format: "Name: last_name" or "Name: first_name"

   else:  #if both names are blank

       return ''  #return ""

 

Explanation:

The working of the above function can be checked by using the following statements:

print(format_name("Ernest", "Hemingway"))  

print(format_name("Voltaire", ""))  

print(format_name("", "Madonna"))  

print(format_name("", ""))

The program has a function format_name which takes two strings i.e. the first_name and last_name as parameters and returns the formatted string.

The first if condition checks if both the first_name and last_name are blank. For example if first_name = "Ernest" and last_name= "Hemingway" this means both the first_name and last_name are not blank or empty. So If this condition evaluates to true then the following statement is returned:

return ("Name: " + last_name + ", " + first_name)

This returns the last_name string first followed by a comma in between and then first_name string in the last. For the above example the string is printed in the following format:

Name: Hemingway, Ernest    

The elif condition checks if either of the first_name or last_name is blank. For example if first_name = "Voltaire" and last_name= "" this means last_name is blank or empty. So if this condition evaluates to true then the following statement is returned:

return ("Name: " + last_name + first_name)  

This returns the last_name string. For the above example the string is printed in the following format:

Name: Voltaire          

IF none of the above condition is true and both the first_name and last_name are blank then the following statement is returned

return ''  

This will just print and blank space in output.

The program and its output is attached.
