What type of wave do ocean waves represent

Biology
2 answers:
sasho [114]3 years ago
6 0

The waves that are present in deep ocean are longitudinal waves and the waves on the surface are referred to as surface waves in which particles undergo circular motion. The surface waves are neither transverse nor longitudinal. The shallow water waves include the tidal waves which are formed by the gravitational attraction of the sun and the moon and blowing winds while seismic waves are caused due to the earthquakes inside the ocean. The internal waves are formed when there is a disturbance between two water masses having different density.

A researcher is curious if Bt resistant bollworms are susceptible to an insecticide called DDT. Bollworms susceptible to Bt have
Shalnov [3]

Answer:

The correct answer is - 3/16 or 18.75% portion will be resistant to both Bt and DDT.

Explanation:

It is given that bollworms that are susceptible to Bt are represented by either RR or Rr and resistance one are shown by rr genotype and bollworms that are resistant to DDT are represent TT or Tt genotype and susceptible to DDT have tt genotype.

Cross: RR tt with rr TT

Gametes: Rt and rT

F1 cross:

    RT

rT  RrTt ( susceptible Bt and resistant DDT)

F1 Cross with F1

Gametes: RT, Rt, rT and rt

cross:

             RT      Rt        rT         rt

RT       RRTT   RRTt   RrTT    RrTt

Rt        RRTt    RRtt    RrTt      RrTt

rT       RrTT    RrTt     rrTt       rrTt

rt       RrTt      Rrtt     rrTt      rrtt

The bold genotypes are the three out of 16 that are resistant to both DDT and Bt.

Rank each of the following events of the ovarian cycle in chronological order using #1 to identify the earliest event. 61 Rank t
denis23 [38]

Answer:

1. The follicular phase begins

2. FSH stimulates the maturation of follicles  

3. Estradiol increases the dominant follicle's sensitivity to the gonadotropins

4. FSH secretion diminishes and non-dominant follicles degenerate.

5. A surge in LH stimulates the primary oocyte in the dominant follicle to complete meiosis

6. The secondary oocyte is formed and the dominant follicle ruptures (ovulation).

7. The follicle collapses and bleeds and becomes the corpus luteum.

8. The corpus luteum secretes progesterone helping to prepare the uterus for a possible fertilization

Explanation:

Ovocites production in all vertebrates is cyclic. It involves hormones interaction and changes in follicular cells and uterine walls. The hypothalamus is in charge of this cycle, and the hormones involved are the estrogens and progesterone, hypophysis hormones FSH and LH, and the hormone that releases gonadotrophins GnRH. In reduced concentrations, estrogens act by negative feedback inhibiting the production of FSH, GnRH, and LH. In high concentrations, by positive feedback, estrogens stimulate the GnRH secretion and enhancing the synthesis of FSH and LH hormones. Under the high concentration of progesterone, the secretion of all these hormones is inhibited.    

At the beginning of the menstrual cycle, the hormonal levels are low. After a few days, oocytes and follicles start to maturate under the influence of the gonadotrophic hormones FSH and LH. As the follicle increases in size, it secretes estrogen that stimulates the endometrium´s regeneration to make the fertilized ovule implantation possible. The rapid increase in estrogens level in the middle of the cycle provokes an increase in LH release, which also stimulates the oocyte release (ovulation) that goes to the uterus. Under the stimulation of the LH, the follicle cells increase in size and produce the luteal body. Cells of this last one increase in size and secrete progesterone and estrogen. The high levels of these two hormones inhibit the secretion of  GnRH and thus the secretion of FSH and LH.      

If there is not fertilized and implanted egg, the luteal body is reabsorbed and the production of the ovarian hormones decreases. Under low hormones concentration, the endometrium loses part of its wall by eliminating as the menstrual fluid. When the ovarian hormones decrease, hypophysial gonadotrophic hormones increase again followed by the development of a new follicle and the increase in estrogen levels when the cycle starts all over again.
