Answer:

C) all chinchilla

Explanation:

As we know that dominance of alleles for the coat color in rabbits goes like this:

                                          C+ > Cch > Ch > C.

  • The allele for full colour or agouti is  designated as C+.
  • Allele for mutant coat color  silvery- gray coat-chinchilla is Cch.
  • Allele for “Himalayan” coat is called ‘Ch
  • Albino rabbits have whole white coat and allele for this is c

If we cross homozygous chinchilla with homozygous chinchilla the cross will look like this:

P1:                                            chinchilla x chinchilla

P1:                                             Cch Cch    X   Cch Cch

F1:                                          Cch Cch       :       Cch Cch

Since all offspring have Cch Cchgenotype that is foe chinchilla phenotype  it means that all the offspring will have chinchilla phenotype that makes option C correct.

Hope it help

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.

Chiasma form during meiosis I but not during mitosis. <br> a. True <br> b. False
Goryan [66]

Answer:

True

Explanation:

Chiasma is the site of crossing over. It is an X-shaped site that appears in a tetrad (bivalent) chromosome during the diplotene stage of prophase I of meiosis I. Crossing over refers to the exchange of segments of chromatids and occurs between homologous chromosomes only. Crossing over is the event of prophase I of meiosis I and produce new gene combinations.

The homologous chromosomes are separated from each other but remain attached at chiasmata. The dissolution of chiasmata occurs by the end of prophase I and separates the homologous chromosomes completely from each other. Crossing over does not occur in mitosis. Since mitosis does not include crossing over, chiasmata are also not formed in mitosis.

Lab report on mass and motiom golf ball, rubber ball, plastic ball
Tasya [4]

Answer:

Mass and density in the increasing order among the mentioned balls are as follows: golf>rubber>plastic whereas Motion of rubber ball is higher than of golf and plastic ball due to elasticity of the rubber.

Moment of inertia of the ball is dependent on the mass and velocity of the balls which in turn will determine the motion of the balls. Elasticity property of the rubber ball will help to provide opposite force and can enhance the motion of the rubber ball as compared to golf or plastic balls.
