A population of 2000 seals produces 950 young in one year. In the same period of time, 150 seals die. If 50 seals leave the popu

lation, and 30 seals join the population, what is the overall population change of this seal population?

The total population change of this seal population is 780.

<h3 /><h3>What is Population change?</h3>

Population change refers to the difference in size of a population over a

given period of time which is usually one year.

Population size = 2,000

Offspring= 950

Death = 150

Immigration= 30

Emigration= 50

Population change+ Offspring + Immigration - Death - Emigration

2000+ 950+ 30 - 150 - 50 = 2,780

Population change= Final population- Initial population

                               =2780 - 2000

                               =780

Simple epithelia have more layers for protection, whereas stratified epithelia allow materials to move across them and are less
xeze [42]

Answer: False.

Explanation:

Epithelial tissue is found in the linings of many structures throughout the body. There are two kinds of epithelial tissue: simple and stratified. And they  perform different functions and are structured differently.

The simple epithelium consists of one single layer of cells. In this way, all cells are in direct contact with the basement membrane and are separated from the connective tissue. The main function of this epithelium is <u>absorption and filtration.</u>

The stratified epithelium is composed of many layers of cells that are stacked together. In this way, this epithelium has the function of <u>protecting against physical and chemical damage.</u>

An acidic solution of pH 5 has<br> TIMES as many hydrogen ions (H+) as does a solution of pH 6.
Artyom0805 [142]

The difference in concentration of hydrogen Ions between pH5 and pH6 is - x 10.

The pH scale is a scale or measure to find the strength of acidity or the basic nature of a solution or substance. pH 1 is acidic and pH 14 is the most basic on the scale.

  • The concentration of hydrogen ions is inversely related to its pH
  • More hydrogen ions present, the lower the pH
  • The fewer hydrogen ions, the higher the pH We know,

pH = -log(H+) then,    

=> 5 = -log (H+)

=> H+ = 10^{-5} (for pH = 5)    

=> pH = -log(H+)  

=> 6 = -log (H+)  

=> H+ = 10^{-6}  (for pH = 6)  

Thus, The substance with the lower pH (5) has 10 times as many hydrogen ions per volume of water.

Marissa is testing a hypothesis through experimentation. She believes that immersing ocean coral in carbonic acid will slow the
motikmotik

Answer:

The answer choices to this question are:

A) She releases cement particles into a random number of the coral samples.

B) She uses three different types of coral to establish her dependent variables.

C) She treats the coral samples identically with varying levels of carbonic acid.

D) She obtains her coral samples from coral reefs surrounding different continents.

Best Answer is:

A) She releases cement particles into a random number of the coral samples.

Theory:

It has been researched that ocean acidification caused by carbon dioxide emissions causes a decrement in the coral reef growth and this will keep slowing down unless steep and rapid reductions in greenhouse gas emissions are made. And the Coral reefs offered economic opportunities would advantage the surrounding communities from fishing and tourism.

i did this question so thats why i know the answer choices

hope this helpsss
