Answer:
In plants, dead cells are not excreted, rather, they form key structural elements which support and protect living tissue as the organism grows. Two examples of useful functions are the formation of (1.) xylem vessels and (2.)sclerenchyma.
Explanation:
- Xylem vessel: mature xylem vessel is made up of dead cells called <em>vessel elements</em> aligned end-to-end; here, the ends are dissolved and the protoplasm is absent. These form long, continuous tubes that facilitate the unobstructed flow of water and minerals to other areas within plants.
- Sclerenchyma are comprised of dead cells which have secondary walls reinforced with lignin. In plants, they provide key structural support and greater mechanical strength to prevent damage or tears within the plant tissue.
The answer is 1 the slugs with chloroplast no longer need to carry out reputation.
The genotype of the mother must be heterozygous.
<h3>Punnet' square</h3>
In order to obtain a probability of 25% red-eyed males from the offspring, the mother must be heterozygous for the trait. The father can be of any genotype.
Thus, the likely genotype combination that will result in 25% red-eyed males are:
x 
- and
When you cross the first one above, the genotype of the offspring would be 
.
The second cross will give offspring with the genotypes 
Both crosses give a 25% chance of producing re-eye males.

Given what we know, we can confirm that if a population of animals has a short gestational period and travel in large groups, this will result in increased mating leading to higher birth rates and an increase in individuals.
<h3>How is the gestational period related to birth rates?</h3>
- The gestational period refers to the time it takes an organism to fully develop a newborn.
- This means that a pregnant female of this animal group will not take very long to give birth.
- This also implies a short recovery period.
- This results in the females being able to breed more often and thus will increase birth rates.
Therefore, given that the females in the group will carry the fetus for very short amounts of time due to the short gestational periods, they will become available to breed more often and thus will result in higher birth rates and increased population size.

Answer: This is an example of organizational heirarchy.
Explanation: These biological structures are designed in a way that the whole system consist of different parts serving its own unique purpose, making up a full functional system. It goes from; atoms, molecules,cells, tissues and organs which makes up a system. Digestive system for example is composed of atoms, molecules,cells, tissues and organs that helps to digest amd convert food into energy(ATP).
