The statement embryonic stage is the first phase of the prenatal stage, lasting only two weeks after conception is false.
What do you mean by Embryonic stage?An embryonic stage may be defined as the period after implantation, during which all of the major organs and structures within the growing mammal are formed.
The first two weeks after conception are known as the germinal stage, not the embryonic stage. The third through the eighth week is known as the embryonic period, and the time from the ninth week until birth is known as the fetal period.
Therefore, the statement embryonic stage is the first phase of the prenatal stage, lasting only two weeks after conception is false.

When does a zygote become an embryo?
once the embryo forms a heart, lungs, and brain
a few minutes after the male and female gamete fuse
once the zygote enters a safe environment either inside or outside of their mother
once the zygote starts dividing by mitosis and cell differentiation occurs
Answer:
Explanation:
The transformation of a zygote into an embryo adheres both to nature and to nurture: not only genetics but also environment determines the outcome. This idea has assumed many forms. A territory in the early sea urchin blastula contains clones of founder cells, and each clone contributes exclusively to one territory (Cameron & Davidson, 1991). Both the lineage of a founder cell, i.e. its nature, and the position of a founder cell, which determines how it is nurtured, contribute to its fate. Fertilisation, the topic of the first Forum, fixes the genes; interblastomere communication, the topic here, regulates gene expression. Blastomeres communicate like any other cell – via ligand-receptor interactions and through gap junctions. Saxe and DeHaan review these mechanisms. The definition of ligands and receptors becomes broadened in this context, and cell adhesions as well as gap junctions enter into the story. In spite of these entanglements, it appears that nature uses the same sorts of mechanisms to get cells to specialise that she uses to keep them talking. Thus, neurons and glial cells signal to one another via glutamate receptors and gap junctions (Nedergaard, 1994). Likewise, we expect neurotransmitters (and neurotransmitter transporters) to help signal differentiation. The biophysicist may ask whether electrical properties also play a role, but that we reserve for another Forum. If gap junctions figure in development as fusion pores that pass small molecules and electrical signals between blastomeres, another parallel suggests itself. Brian Dale asked in the first Forum: How does a spermatozoon activate an oocyte? This question, which concerns gamete communication, has produced two schools of thought and remains controversial (Shilling et al., 1994). Do sperm activate oocytes via contact-mediated mechanisms or through fusionmediated mechanisms? Or do both mechanisms occur, as they appear to in development?

Why is nuclear fusion currently not feasible as a source of electrical energy?
Answer:
Fusion is generally impossible because the strongly repellent electrostatic forces between the positively charged nuclei prevent them from colliding and fusing. One of the key reasons we haven't been able to realize the promise of fusion is because its energy requirements are outrageously large. High-energy neutrons are produced during fusion reactions, although they are not radioactive in and of themselves. They do, however, have such a strong influence on the reactor's walls.

How does the haploid form of ulva switch to its diploid form?.
The haploid form of Ulva switches to the diploid form when gametophytes produce cells that undergo mitosis to produce gametes that fuse to form a zygote. Therefore, option D is correct.
What are gametophytes?The sexual stage in the alternation of plant generations and some algae is called a gametophyte. This stage results in gametes that go through generational alternation. It produces the zygote from which sporophytes develop and is a haploid phase.
The gametophyte stage of life is the predominant one in bryophytes. The male and female gametes are produced by the gametophyte's antheridia and archegonia, respectively. Gametangia are all of these structures put together.
Thus, the haploid form of Ulva switches to the diploid form when gametophytes produce cells that undergo mitosis to produce gametes that fuse to form a zygote. Therefore, option D is correct.

Hemophilia is an X-linked recessive genetic disorder. A baby girl is found to have inherited the trait from her parents. What are the phenotypes of the parents?
X-linked genes are inherited. The affected girl's father is hemophilic (X-Y), and the mother might be either hemophilic (X-X-) or carrier normal (X+X-).
What are the X-linked genes?
These are the genes located in the X séx chromosome and not in the somatic ones.
Traits coded by these genes are inherited. This is, X-linked genes are transmitted from parents to children through generations.
According to this, X-linked genetic disorder will be inherited as well.
Men have a high probability of being affected since they only have one copy of the X chromosome. In women, the effect of the mutation might be musk in heter0zyg0us state.Hemophilia is a X-linked recessive genetic disorder.
Let us represent the recessive allele with the symbol -, and the dominant allele with the symbol +.
X- is the chromosome carrying the recessive allele X+ is the chromosome carrying the dominant alleleFor the affection to be expressed, the person must be either,
X-X- ⇒ woman/girlX-Y ⇒ man/boyIf the baby girl is found to have inherited the trait from her parents, then her genotype is X-X-. She must have received one X- chromosomes from each parent.
Her father provided the X chromosome, so he must be hemophilic (X-Y)Her mother provided the other X chromosome, but she can be either a carrier (heter0zyg0us, X+X-) or hemophilic (h0m0zyg0us recessive, X-X-).Options,
Cross 1) affected father x carrier mother
