the follicular phase, granulosa cells secrete estrogen, which stimulates
secretion of gonadotropin-releasing hormone (GnRH), which then increases
production of luteinizing hormone (LH).
The
follicular phase is the phase of the menstrual cycle, during which follicles in
the ovary mature and it ends with ovulation.
Whelp, it is definitely not D.
I would say B.
there was no Paleogene period.
Lac genes are most effectively expressed in presence of Lactose and its analogs when glucose is absent.
Explanation:
A unit of prokaryotic gene expression and regulation,which includes structural genes and regulatory sequences recognized by regulatory gene product is called operon.
<em>Lac </em>structural genes are a part of<em> Lac</em> operon. The <em>Lac </em>operon consists of three, structural genes,an operator and a promoter.The product of Lac operon is involved in the conversion of disaccharide lactose into glucose and Galactose.
Lactose and its analogs are inducers of<em> Lac </em>operon. So, the structural genes are best expressed in presence of Lactose. Glucose and galactose are repressors of lac gene so the genes are repressed in presence of glucose.
Convert carbon dioxide gas to oxygen gas.
produce the food the plant needs to grow.
However, some folks have missed the purpose of photosynthesis. It's not oxygen production. The primary function of photosynthesis is to convert solar energy into chemical energy and then store that chemical energy for future use. For the most part, the planet's living systems are powered by this process
Answer:
many alveoli are present in the lungs with a shape that further increases surface area. Thin walls - alveolar walls are one cell thick providing gases with a short diffusion distance. Moist walls - gases dissolve in the moisture helping them to pass across the gas exchange surface.
