<h2>Answer:</h2>

<u>Eucariotic cells contain DNA</u>
<u>All cells except reproductive cells contain chromosomes</u>

<h2>Explanation:</h2>

1) Eukaryotic cells are cells which contain a nucleus and organelles, and are packed up by a plasma membrane. Examples of organisms that have eukaryotic cells are protozoa, fungi, plants and animals. All of these types of cells contain DNA.Genes are composed of DNA, and it is predicted that there are over 3 billion basepairs in the human genome.

2) All the human cells have 23 pairs of chromosomes which are 22 pairs of autosomes and one pair of sex chromosomes, which means a total of 46 per cell. The only human cells that do not contain pairs of chromosomes are reproductive cells, or gametes. These cells just one copy of each chromosome.

<h3>How can a leader emphasise the principles of their vision?</h3>

Additionally, the appropriate terminology must be used while articulating a vision. A leader need to employ energising and exciting language and imagery (Sashkin, 2004; Zaccaro & Banks, 2001). A vision needs to be described in words that are reassuring, inspiring, and positive while yet undervaluing it.

The attitude, beliefs, and behaviours of the vision must be modelled by leaders. Values are concepts, opinions, and conduct that people deem to be desirable.

The vision of a leader is always complete.

Analogous structures include wings in birds and insects homo-logous structures are DNA sequences due to a common origin, and a vestigial structure can be the human appendix.

<h3>What are analogous structures?</h3>

Analogous structures are traits that have the same function but they originated in different lineages.

Conversely, homo-logous structures have the same common origin but they may play different functions.

In conclusion, wings in different taxonomic groups may represent analogous structures, DNA sequences are homo-logous structures when they have the same ansestor and the human appendix is a vestigial structure.

You are testing a new sugar replacement that you think is indigestible (and potentially useful in diet products). You feed 1 gra

enyata [817]

Answer: The % digestibility of the sugar alternative is 10.

Explanation:

First we have to know how many grams of the sugar replacement were in the total rat feces. We know 22,5% of the feces were the sugar replacement, so we use cross multiplication for that:

If 20 grams is 100% of the feces, then

x grams / 22.5% = 20grams / 100%

xgrams = (22.5 . 20grams) / 100% = 4.5grams

If each rat ingested 1gram of the sugar replacement, all five rats ate a total of 5grams.

Now we have to check how much of this sugar replacement was digested. If the rats ate 5grams and 4.5grams were present in their feces

5grams - 4.5grams = 0.5grams

This means they digested 0.5grams.

We use cross multiplication again to find out which percentage of the initial sugar replacement this represents.

If 5grams is 100% of the ingested sugar replacement, then

x% / 0.5grams = 100% / 5grams

x% = (0.5grams . 100%) / 5grams = 10%
