Answer:

The Viking tubing is meant to be the cell membrane. Glucose manages to move out of the bag and into the surrounding water but starch does not. Not all substances can pass through the cell membrane; some molecules, like starch are too large. The cell membrane is called selectively permeable because of this.

lions [1.4K]

Answer:

(i) Yeast- Kingdom Fungi

(ii) Penicillium- Kingdom Fungi

(iii) Rhizobium- Kingdom Eubacteria

(iv) Mushroom- Kingdom Fungi

(v) Amoeba- Kingdom Protista

(vi) fish- Kingdom Animalia

Explanation:

Living organisms were classified into a large group called KINGDOM, which represent the largest and most generic grouping consisting of organisms that share a few similarities. The kingdoms that living organisms were classified into are as follows: Plantae, Animalia, Fungi, Protista, Eubacteria, Archaebacteria, etc.

Based on the question, the mentioned organisms are classified into the following kingdoms:

(I) Yeast: Yeast is a unicellular microbe classified under the Kingdom Fungi due to possession of chitin in its cell wall and other similar features with members of kingdom Fungi.

ii) Penicillium- Penicillium is a genus classified under the Kingdom Fungi.

(iii) Rhizobium- Rhizobium is a genus of prokaryotic organism (lack membrane-bound nucleus and organnelles) classified under the Kingdom Eubacteria.

(iv) Mushroom- Mushrooms are saprophytic (heterotrophic) species of organisms classified under the Kingdom Fungi.

(v) Amoeba- Amoeba is a genus of unicellular eukaryotes classified under the Kingdom Protista.

(vi) fish- Fishes are organisms classified under the Kingdom Animalia

A performer, seated on a trapeze, is swinging back and forth with a period of 8.90 s. If she stands up, thus raising the center

iren2701 [21]

Answer:

8.800s

Explanation:

When the performer swings, she oscillates in SHM about Lo of the string with time period To = 8.90s.

First, determine the original length Lo, where for a SHM the time period is related to length and the gravitational acceleration by the equation

T = 2π×√(Lo/g)..... (1)

Let's make Lo the subject of the formulae

Lo = gTo^2/4π^2 ..... (2)

Let's put our values into equation (2) to get Lo

Lo = gTo^2/4π^2

= (9.8m/s^2)(8.90s)^2

------------------------------

4π^2

= 19.663m

Second instant, when she rise by 44.0cm, so the length Lo will be reduced by 44.0cm and the final length will be

L = Lo - (0.44m)

= 19.663m - 0.44m

= 19.223m

Now let use the value of L into equation (1) to get the period T after raising

T = 2π×√(L/g)

= 2π×√(19.223m/9.8m/s^2)

= 8.800s
