Answer:
True
Explanation:
Oogenesis includes the formation of one egg cell from a single oocyte or egg mother cell. The diploid primary oocytes in the ovaries enter into the first meiotic division and form a haploid secondary oocyte and a haploid first polar body. After fertilization, the secondary oocytes complete the meiosis-II and forms one large ovum and a second polar body. The ovum formed by meiosis-II is much larger than the second polar body due to the unequal distribution of cytoplasm during meiosis-II. This imparts enough amount of cytoplasm in the zygote to support the mitosis without any cell growth.
Answer: start seeds as early as mid-January
1 to 1 1/2 inches of water each week
Use as much sunlight as you possibly can
Mulch and prune them
explanation:
Gas exchange occurs in the alveoli of the lungs and each is made from a single layer of flat cells, Many alveoli in the lungs, so a large surface area for exchangement of C02 and O2. They are surrounded by a network of capillaries and oxygen diffuses out of them via the alveolar epithelium to the hemoglobin.

Most of the marine animals have a stream lined body, which means, they have a sharp and pointed at the front. The pointed front of the organism allow to cut the resistance of the water. In case, the body is not pointed at the front and it is blunt, the water current and flow would resist the movement of the organism further. So, for the locomotion purpose, it is important to have a streamlined body. Further smooth and hair less body also decrease the resistance during the movement in the water.
<h2>Maternal effect</h2>
Explanation:
In maternal effect the phenotype of the progeny is decided by the genotype of the mother
- The female partner is one step ahead to her male partner
- The ovum transcribes some of its nuclear genes prior to fertilization and these genes are responsible for the development of embryo that is why these genes are called maternal effect genes
- This effect is observed in Drosophila
In the given question both male and female have brown eyes with Nn genotype,phenotype of the offspring will be decided by the genotype of mother(Nn) hence despite of having recessive genotype(nn) all the offsprings will show brown eyes
