Multicellular fungi share some key traits, including their body structures, growth patterns, and methods for absorbing nutrients. however, although their feeding methods may be similar, fungal species differ markedly in their sources of nutrients, which include both living and dead organisms. as a result, fungi play a variety of roles in ecological communities.

Answers

Explanation:

The structure of multicellular fungi is formed by filaments called hyphae, and the set of hyphae is called mycelium. Hyphae are made up of the substance chitin.

They can be of two types: vegetative or reproductive. In vegetative multicellular fungi, hyphae are found inside the substrate to remove the food.

And in the case of reproductive multicellular fungi, there is the formation of spores, which will form the fruiting body for reproduction.

The track star runs 100m at a rate of 10.4m/s. How long did it take to run 100m?

Answers

Answer:

Time, t = 9.62 secs.

Explanation:

Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.

Mathematically, speed is given by the equation;

[tex]Speed = \frac{distance}{time}[/tex] ....equation 1

Making time the subject formula;

[tex]Time = \frac{distance}{speed}[/tex] .....equation 2

Given the following data;

Distance = 100m

Speed = 10.4m/s

Substituting into equation 2;

[tex]Time = \frac{100}{10.4}[/tex]

Time, t = 9.62 secs.

In his experiments, MacDougall placed a dying person on a scale and measured their weight immediately prior to and following death.

Projectile Assignment Create an HTML form that will accept four fields: pet name, pet ID, pet weight, and birthdate. Name this file petInfo.html. There should be a submit and reset button on your html form. Your input fields for your form should be inside of a table. The submit button should send the data to a php file named updateInfo.php. The updateInfo.php file should check the data submitted by the html file for proper formatting. While it is allowable that you may check input on the client side (either HTML or Javascript), you MUST check for valid input on the server using PHP. ***IMPORTANT*** Your POST variables in your HTML file must be labeled as follows. I have written an automated script to run tests on your code, and it depends on the POST variables being labeled correctly within the HTML Form. 1) "pet_name" 2) "pet_id" 3) "pet_weight" 4) "birth_date" The following rules must be enforced by your PHP script about the input. No field is allowed to be blank. Maximum length of pet name is 20 characters. Pet ID must be 4 lowercase letters followed by 3 numbers. Example: abcd123 Max length of pet weight is 7 characters. Max of two digits after decimal point. Must be a positive value. Range: 0.00 9999.99. The name should be only made up of alphabetical characters. (no numbers or symbols). Birthdate should be in the format 1/1/2002. Examples of valid input: 01/01/2002, 12/1/1999, 12/25/2015. Do not allow: 12/25/02 (The whole year should appear in the input).If all the fields are valid, your PHP script should save the data into a file named petInfo.txt which should have the following format, and be sorted by "pet_name". Put each record on its own line. To simplify things, you can assume that Names are unique - i.e. you can use the name as a key for your associative array. (I won't use two of the same name when I test your code). PetName, PetID, PetWeight, PetBirthDate\n Once the new data has been received, you should also display ALL data that has been entered into the text file from your PHP script into an HTML table. The table should be sorted by last name just like the text file. After successfully displaying your table, create a link back to the petInfo.html page.
