Why is the intensity of a pulse different at different sites?

Answers

Answer:

Because pulse wave velocity decreases as arterial diameter decreases, a slight difference in local vasculature can cause inter-site differences not only in pulse transit time but also in its variations.

What happens to air pressure as the altitude increases?
O It gets lower
o It gets higher
0 It stays the same

Answers

Answer:

Pressure with Height: pressure decreases with increasing altitude. The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation. At higher elevations, there are fewer air molecules above a given surface than a similar surface at lower levels.

Explanation:

As altitude rises, air pressure drops.

how are algae cells different from other cells

Answers

Answer:

In the case of the algae, each individual cell is responsible for absorbing its own water. This makes the algae nonvascular compared to the highly vascular plant species. In this connection, algae also lack several key structures that are normally present in ordinary plants like the leaves, roots and stem.

Algae are a group of aquatic organisms with autotrophic metabolism that are made up of eukaryotic cells and we can find unicellular or multicellular individuals.

Some characteristics of algae cells are:

• Cellular organization is eukaryotic (with the exception of blue-green algae), that is, they have a nucleus delimited by a double membrane, mitochondria, chloroplasts, endoplasmic reticulum, Golgi complex and lysosomes.

By definition, this type of cell is one that has a nucleus in which genetic material is stored. Compared to prokaryotic cells, eukaryotes have a large genome.

• The cell wall is made up mainly of cellulose and glycoproteins.

• In the algae cells we can find different reserve substances produced by metabolism.

The reserve substances are mainly starch, although we also find chrysolaminarin, laminarin, mannitol and paramilion in the different groups.

These substances form granules that are dispersed in the cell cytoplasm, in chloroplasts or in pyrenoids.

• They have structures of locomotion called flagella.

In different groups of algae, these organs vary in both number and shape, however, they typically present two flagella or multiples of two.

Therefore, we can conclude that algae are unicellular or multicellular photosynthetic organisms endowed with nucleus, cell wall, flagella and reserve substances.

Answers

Answer:

A. stores genetic info and helps make proteins.

Explanation:

Nucleic acids are DNA and RNA.

The statement that best describes the function of nucleic acid is stored genetic information and helps to make proteins. The correct option is A.

What is nucleic acid?

Nucleic acid is a macromolecule. Nucleic acid is made up of nucleotides. The composition of nucleotides is a 5-carbon sugar, a phosphate group, and a nitrogenous base.

Nucleic acid is the main component of the genetic material of the living organism. They are DNA and RNA. DNA is the main genetic material of animals and plants, and RNA is found in some bacteria and some plants.

DNA and RNA store the genetic information of the organism. As this, nucleic acid also contains genetic material. This genetic information is used in synthesizing proteins.

Thus, the correct option is A. Stores genetic information and helps to make proteins.

Explain 3 ways of checking soil depletion​

Answers

You can check soil depletion by:

1. Contour ploughing

Ploughing along contours on a slope prevents soil from being washed away by rains and or by surface run-offs. Contours act like bunds. Terraces are leveled into step-like small fields with even slopes. Doing this is common in Asian countries.

2. Terrace Farming

On hilly slopes, terraces act as bunds and prevent the soil from being washed away by running water. This is practiced in Asia and the USA.

3. Strip Cropping

In this system, crops are grown by alternate strips of land in order to check the effect of the winds.

Explanation:

in both sides, pressure is the alwyays the same whatever the area is..

First we calculate the pressure at piston A:

P= F÷a

given that,

#F= 20N

#a=1m^2

P= 20÷1

P= 20 Pa.

At piston B:

pressure is the same = 20Pa

Area= 4m^2

P=F/a

F= P×a

F= 20 × 4

F= 80N

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.
