This procedure for measuring cell size has certain limitations . List three such limitations

marusya05 [52]

The limitations of cell size are:

1) Surface area to volume ratio

2) Nucleo cytoplasmic ratio

3) Fragility of cell membrane

What are the cause of limitations on cell size?

The need for a surface area of sufficient area to allow the cells function→.

→If the surface area of cell increase volume increase to the cube of the linear increase.

→ Nuclie contains information needed for protein synthesis . Some cells reduce this limitation to increase the no. Of nucleus called multinucleated.

Examples are muscle cells.

In the figure below, ΔMNO≅ΔPQR.What is the measure of ∠P? Show your work and explain your reasoning.

Juliette [100K]

Answer:

$\huge\boxed{\sf P = 79.5\°}$

Explanation:

<u>Given that:</u>

ΔMNO ≅ ΔPQR

That means

M ↔ P

N ↔ Q

O ↔ R

So,

∠P ≅ ∠M

Given that P = 3x + 20.4 and M = 5x - 19

3x + 20.4 = 5x - 19

Add 19 to both sides

3x + 20.4 + 19 = 5x

3x + 39.4 = 5x

Subtract 3x to both sides

39.4 = 5x - 3x

39.4 = 2x

2x = 39.4

Divide both sides by 2

x = 19.7

<u>Given that:</u>

P = 3x + 20.4

P = 3(19.7) + 20.4 (x = 19.7)

P = 59.1 + 20.4

P = 79.5°

$\rule[225]{225}{2}$

How does the basic structure of a steroid differ from other macromolecules such as carbohydrates?

oksian1 [2.3K]

The basic structure of a steroid differ from other macromolecules such as carbohydrates by having a four ring structure whereas a carbohydrate do not have. A steroid is a group of organic substances which has four rings that are arranged in a certain configuration. Examples are testosterone, estradiol and lipid cholesterol. It will always have seventeen carbon atoms in its structure. Carbohydrates, on the other hand, are a group of organic substances that consist carbon, hydrogen and oxygen atoms typically in a 2:1 ratio of the hydrogen and oxygen atoms. So, it would have an empirical formula of Cx(H2O)y.
