Answer:
Explanation: Guard cells in the plants prevent water loss from it in cases of soil dryness or high temperature by closing themselves. If this does not happen, water will keep leaving the plant by the process of transpiration in these harsh conditions and the plant will not have the important medium for the homeostasis process to continue.
Answer:After witnessing plant and animal cells under a microscope, scientists Schwann and Schleiden made the conclusion that all living organisms are composed of cells. This discovery was significant because it laid the foundation for the cell theory, which states that cells are the basic units of life.
Schwann, a zoologist, observed animal tissues and noted that they were composed of individual cells. Schleiden, a botanist, made a similar observation while studying plant tissues. Both scientists realized that cells were the fundamental building blocks of living organisms.
This conclusion was supported by several examples. For instance, when examining plant cells, Schwann and Schleiden noticed that they had a cell wall and a distinct nucleus. Similarly, animal cells lacked a cell wall but had a nucleus and other cellular components. These observations led them to propose that all living organisms are made up of cells, regardless of whether they are plants or animals.
The discovery of the cell as the basic unit of life revolutionized biology and had a profound impact on our understanding of living organisms. It provided a unifying principle for the study of life and opened the door to further research and discoveries in the field of cell biology.

Answer:
theories, models, and laws
Explanation:
B) decreases the chance that an offspring will receive a dominant allele.
c) increases the genetic variability of the offspring.
D) decreases the genetic variability of the offspring.
Answer: The correct answer is c) increases the genetic variability of the offspring.
According to Mendel's law of segregation, during the process of gamete formation, alleles ( alternative forms of gene) are separated into different gametes ( reproductive cells of the organism). In other words, every gamete consists of one allele. It is also called law of purity of gametes.
Due to this segregation, only single allele is passed from each parent to their offsprings. Thus, in different offsprings, the chances of genetic variability is increased as there is a likelihood that different offsprings will receive different alleles.
Thus, C) is the right answer.
Mendel's Law of Segregation describes the process of alleles separation during meiosis, which results in genetic variability in the progeny. This segregation contributes to a greater genetic diversity, enhancing survival and adaptability in different environments.
According to Mendel's Law of Segregation, during the process of meiosis, a parent organism's alleles separate to form gametes. With each parent's separate alleles moving into different gametes, only one allele will pass from each parent onto an offspring.
Among the options provided, the correct consequence of this process is that it c) increases the genetic variability of the offspring. This happens because the shuffling and separation of alleles ensure a mix of hereditary information in gametes. This mix of parental alleles in the offspring enhances genetic diversity within a population, thereby increasing its ability to adapt and survive in varying environmental conditions.
