Answer:
This question lacks options, options are: A) A visible nuclear envelope B) Separated sister chromatids at each pole of the cell C) Tetrads lined up at the center of the cell D) A synaptonemal complex E) A cleavage furrow. The correct answer is C.
Explanation:
During Metaphase I, the chromosomes line up at the midpoint or equator between the poles of the cell and are found at their thickest and shortest structure, that is, the tetrads line up at the equator of the cell. They are identified as two double longitudinal sister chromatids. In animals and plants, the chromatids are connected (at their centromeres) to the fusiform apparatus, which has formed between the two centrioles located at the poles of the cell. In many plants, the centrioles are absent. However, the spindle is still present and the plant chromosomes are attached similarly to the microtubule fibers of the spindle.

What is the distinction between mitosis and meiosis?Mitosis outcomes in two nuclei might be equal to the authentic nucleus. Meiosis, on the other hand, outcomes in 4 nuclei, every having half of the variety of chromosomes of the original cell. In animals, meiosis handiest happens within the cells that deliver rise to the sex cells (gametes), i.e., the egg and the sperm.
Mitosis includes the division of frame cells, even as meiosis entails the division of sex cells. The department of a cellular takes place as soon as in mitosis however twice in meiosis. two daughter cells are produced after mitosis and cytoplasmic department, at the same time as 4 daughter cells are produced after meiosis.
Mitosis includes one degree whereas meiosis consists of ranges. Mitosis produces diploid cells (forty-six chromosomes) whereas meiosis produces haploid cells (23 chromosomes). Mitosis produces two same daughter cells whereas meiosis produces four genetically exclusive daughter cells.

4) What is a zygote? How does the zygote form the organism?
A zygote is a fertilized egg cell resulting from the fusion of a sperm cell and an egg cell during sexual reproduction. It marks the beginning of a new organism's life.
After fertilization, the zygote undergoes a series of cell divisions called mitosis, where it divides into multiple cells, forming a structure known as a blastocyst.
The blastocyst then undergoes implantation in the uterus, where it develops into an embryo. As the embryo continues to grow and differentiate, it forms the various tissues, organs, and systems of the developing organism.
The zygote serves as the initial building block and contains all the genetic information necessary for the organism's development.

During which part of meiosis (meiosis I or meiosis II) do the two alleles of a gene separate? During which phase does the separation occur? (Assume no recombination.)
Answer:
meiosis 1, anaphase
Explanation:
Meiosis is a type of cell division that consists of two rounds of cell division known as Meiosis I and Meiosis II, and one round of DNA replication, thereby the resulting cells (gametes) contain half of the genetic material found in somatic (body) cells. Both Meiosis I and Meiosis II can be divided into the following phases: Prophase, Metaphase, Anaphase, Telophase and Cytokinesis. Alleles of a gene separate during the anaphase of Meiosis I (i.e., Anaphase I), because homologous chromosome pairs separate during this phase of the cell cycle.
Answer:
During the ANAPHASE of MEIOSIS I, IF there is no recombination, the two alleles of a gene separate
Explanation:
Meiosis is a process by which, from a diploid germ cell (2n), four daughter cells with a haploid chromosome number (n) are produced. Each daughter cell has half of the chromosomes of the original one. There are two phases in meiosis: the first one in which occurs a chromosome´s reduction division, and the second one where the cell suffers a new division, but this one is not a reductive one.
If there is no recombination or crossing-over between a locus and the centromere, during anaphase of meiosis I, occurs the separation of the alleles. One of the alleles migrate to one pole and the other migrates to the other pole .But if it occurs crossing-over, the allele separation occurs in the anaphase of meiosis II, when chromatids separate.Which of the following statements is true regarding individual III-5? Select all that apply. Select all that apply. Individual III-5 is male. Individual III-5 is female. Individual III-5 is affected by the genetic condition. Individual III-5 is not affected by the genetic condition. Individual III-5 is the proband.
Answer:
III-5 is male.
Individual III-5 is affected by the genetic condition.
Individual III-5 is the proband.
Explanation:
In human pedigrees, males are represented by squares while females are represented by circles. Individuals affected by the focus trait in human pedigrees are usually shaded, those that are carriers are half-shaded, while those that are not affected at all are not shaded in any form.
Thus, from the pedigree (see the attached image), III-5 individual is a male and affected by the genetic condition in focus.
Also, III-5 individual is a proband, because a proband is an individual that is first affected by a genetic trait in a family.

An example of a(n) is the brain, spinal cord, and nerves working together.
Answer:
system
Explanation:
An example of an organ system is the brain, spinal cord, and nerves working together.
A system is a level of organization in living organisms in which body organs work together to perform similar functions. The organ system represents the highest level of body organization as opposed to organ, tissue, and cell level of organization.
The cell is the smallest unit of organization of the body of living organisms. At the tissue level, cells aggregate together to perform similar functions while at the organ level, similar tissues come together to perform somewhat similar roles in the body of organisms.
The brain, spinal cord, and nerves each represent an organ. When these work together in the body of organisms, the level of organization is described as organ systems or simply systems.

Both the endocrine and nervous systems are major regulating systems of the body; However, the nervous system has been compared to an airmail delivery systtem and the endocrine system to the pony express. Briefly explain this comparison.
Answer:
The correct answer is -the nervous system is rapid whereas the endocrine is slow and effective on distant target organs.
Explanation:
Both the nervous system and endocrine system are essential and major regulating or controlling systems in an organism. The nervous system ae compared to airmail as it uses nerve stimulus to bring rapid control whereas the endocrine is like pony express as it acts much more slowly.
The nervous system is fast and rapid and required electrochemical stimulus or impulses whereas the endocrine system produces hormones and releases them to the blood which then travels to the target organ and binds to it.

4. Eukaryotes: Opisthokonts: Animals: Protostomes: Ecdysozoa: Arthropods
Explanation:
Taxonomy is the study of different organisms, their classification into categories according to their morphological and molecular characteristics and their evolutionary relationships, and assigning to each them a binomial name.
The eukarya domain is composed of all the unicellular or pluricellular organisms that have eukaryotic cells that characterize by having a well-defined nucleus surrounded by a complex biological membrane. They also present organelles delimitated by membranes. These organisms reproduce asexually and sexually. Animalia Kingdom: Includes different phyla closely relates. The embryonary development of bilateral coelom animals makes a place for the division of two groups: protostomes and deuterostomes. Among protostomes might be mentioned the flatworms, annelids, mollusks, and arthropods. Protostomes show spiral initial segmentation, and the mouth develops as a first opening near the blastopore. Ecdysozoan Superphylum: Their bodies are covered by a cuticle that provides protection. They have a complete digestive system. They might reproduce sexually and asexually.Phylum Arthropoda: Invertebrates characterized for having an exoskeleton, a segmented body, and articulated appendixes. A very diverse group with many different characteristics.True or False: Chromosomes can be seen with the naked eye.
the answer is false Because it is so thin, DNA cannot be seen by the naked eye unless its strands are released from the nuclei of the cells and allowed to clump together.

Using the Gizmo, create four energy paths to explain how the toaster could get its energy.
Answer and Explanation:
Energy is well-defined as the capacity to do work. Heat is the kind of energy. It is transmitted from the high-temperature object to the low-temperature object. When electricity runs over a wire, energy is transferred from one end of the wire towards another end. Electricity flow in the wire by electrons. When electricity flows, the electrons collide with one another and give off heat due to collision. Less collision of electrons produce less heat, and more collision of electrons produce more heat. When the toaster wire plugged into the electricity supply, electric energy began to flow through the wire—the electric current run over a series of filaments. The filaments are thin and connected. When electric energy flows through the filaments, they glow red hot and transfer the bread. The filaments are present on both sides of the toaster. So the bread cook from both sides at a similar time.
