The life cycle of plants involves into two parts, first is the diploid phase and the second would be the haploid phase. Therefore, the answer would be letter A. Palm trees are known to be perennial plants and usually grows in the environment that are warm and more humid.
Answer:
False
Explanation:
This statement is false because knowledge is more like a way of getting at the truth.
A justified and true belief is necessary and sufficient for knowledge. In philosophy, the study of knowledge is called epistemology, and according to Plato and traditional definition, knowledge is "justified true belief."
ANSWER: Biological biodiversity refers to all the different kinds of life that are obtainable in a particular ecosystem, this include all the plants and animal populations that are found in a particular geographical area.
Biodiversity supports healthy ecosystem because it enhances the productivity and the survival of the ecosystem. For instance, in a situation where there are large number of different plant population in an ecosystem, such population will present variability in genetic make up. If a negative event occur in the ecosystem, it will be possible for some plants to survive. But, in a situation where it is only one type of plant that is obtainable in the ecosystem, it will be quite easy to wipe all of them out at once. For instance, a disease outbreak can easily destroy all the plants.
Explanation:
During the process of prophase I, the nuclear envelope containing chromosomes has only partly broken down homologous chromosomes are joined together by proteins and a complex or pairing call synapsis- corresponding genes on sister chromatids are aligned precisely.
The syanapsis allows for crossing over which is the exchange of segments of chromosome, between non-sister homologous or similar chromatids crossing over happens at chiasmata, the point where non-sister chromosomes are joined.
Further Explanation:
All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. In meiosis, the number of chromosomes (2n) is halved to 23 chromosomes (haploid number)through meiotic divisions, producing 4 haploid (n) germ cells or gametes (sperm or eggs), each containing half the number of chromosomes as its parent cell.
In Meiosis I
- homologs pair off into bivalents
- At crossing over: the exchange of segments of chromosome, between non-sister homologous or similar chromatids crossing over happens at chiasmata, the point where non-sister chromosomes are joined in prophase I forming bivalents; tetrads are formed.
- Spindle fibers from centrioles join sister chromatids together at their centromeres in metaphase I, pulling them to the equator of the cell;
- then, in anaphase I, while joined, they are pulled to opposite sides of the cell; the cell body splits and the nuclear envelope reforms in telophase I
In Meiosis II...
- Later, in prophase II, the nuclear envelope disintegrates and mitotic spindle fibers are formed
- independent assortment occurs. in metaphase II of meiosis: spindle fibers attach to centromeres, chromatids align independently at the equator. Genes segregate independently into new combinations as sister chromatids are pulled apart by their centromeres in anaphase II
- in telophase II the cells' nuclei and membrane are then formed with each containing the haploid number (n)
- Following the formation of gametes in the last stage, randomized fertilization occurs in sexual reproduction sperm cells fertilize an ovum to form a zygote. This occurs randomly by chance, to result in a complete set of chromosomes 2n, that is a novel combination of half each parent's number of chromosomes
