<h2>Ovulation </h2>
Explanation:
In women, luteinizing hormone carries out different roles in the two halves of the menstrual cycle
- In week one to two of the cycle, luteinizing hormone is required to stimulate the ovarian follicles in the ovary to produce the female sex hormone, oestradiol
- Around day 14 of the cycle, a surge in luteinizing hormone levels causes the ovarian follicle to tear and release a mature oocyte (egg) from the ovary, a process called ovulation
- For the remainder of the cycle (weeks three to four), the remnants of the ovarian follicle forms a corpus luteum
- Luteinizing hormone stimulates the corpus luteum to produce progesterone, which is required to support the early stages of pregnancy, if fertilization occurs
I think it’s true because they contain a code with a specific protein that function s in one or more types of cells
Genotype refers to the complete genetic make-up and can also be referred to as the alleles an organism carries on a particular gene.
John's genotype with unattached being dominant is Aa.
- Using A to represent the alleles
- Since his mother has attached earlobes, her condition can only be inherited in the recessive condition (aa).
- So for John to have an unattached earlobe, his father has to be either AA or Aa.
- Therefore John's genotype would be Aa

<h2>c.is the correct option</h2>
Explanation:
Fungi might assist in seed germination by providing the embryos with some of the organic nutrients the fungi have absorbed
- Fungi is an eukaryote which digests food externally and absorbs nutrients directly through its cell walls
- Fungi absorb nutrients through following three ways:
- By decomposing dead organic matter: obtains its nutrients from non-living organic matter, usually dead and decaying plant or animal matter, by absorbing soluble organic compounds
- By feeding on living hosts:fungi live in or on other organisms and get their nutrients from their host
- Living mutualistically with other organisms: mutualistic fungi live harmlessly with other living organisms;fungal component absorb water and minerals and provide them to algal component which uses them to make food
In dark,moist environment nutrient availability is less hence fungi helps in providing orchid seeds the nutrients which it has absorbed
