Networks of blood vessels in bats' wings serve only to disperse heat generated in flight. This heat is generated only because bats flap their wings. Thus paleontologists' recent discovery that the winged dinosaur Sandactylus had similar networks of blood vessels in the skin of its wings provides evidence for the hypothesis that Sandactylus flew by flapping its wings, not just by gliding.The argument in the passage relies on which of the following assumptions?(A) Sandactylus would not have had networks of blood vessels in the skin of its wings if these networks were of no use to Sandactylus.(B) All creatures that fly by flapping their wings have networks of blood vessels in the skin of their wings.(C) Winged dinosaurs that flapped their wings in flight would have been able to fly more effectively than winged dinosaurs that could only glide.(D) If Sandactylus flew by flapping its wings, then paleontologists would certainly be able to find some evidence that it did so.(E) Heat generated by Sandactylus in flapping its wings in flight could not have been dispersed by anything other than the blood vessels in its wings.

When we see chiasmata under a microscope, that lets us know which of the following has occurred? A) asexual reproduction
B) meiosis II
C) anaphase II
D) prophase I
E) separation of homologs

Answers

When we see chiasmata under a microscope, that lets us know that prophase I has occurred. During this phase of meiosis, the nuclear envelope breaks up and disappears, and so does nucleolus. The chromosomes become visible at this point.

Which of the following checkpoints determines if DNA replication was successful? a. G2
b. G1
c. M

Answers

Checkpoints that determines if DNA replication was successful is a. G2. There are two checkpoints in the cell cycle. The G1 checkpoint is right before the S phase and if something is wrong, phase will not occur. The G2 checkpoint is right before the M phase (mitosis). It is DNA damage checkpoint and it determines if DNA replication was successful.

__5__Prostate gland adds a fluid that protects the sperm.

__6__Muscles at the base of the bladder contract, forcing semen through the urethra.

__7__Semen is ejaculated into the vagina.

__8__Sperm migrate through cervix and into uterus.

__9__Sperm encounter oocyte in oviduct (fallopian tube).

__10_Acrosome releases enzymes that break down outer layer of egg’s membrane.

__11_Cell membrane changes electrical characteristics, causing cortical reaction.

__12_Male and female chromosomes congregate, restoring the diploid (2n) number.

Fertilization is the process by which gametes of the male and female fuse with each other to form a zygote. In humans, it takes place inside the female body.

The events can be categorized as:

Pre-fertilization events: Sperm (or semen) in male and egg in the female is produced in testes (in males) and ovary (if females) respectively. Accessory glands such as seminal vesicle, bulbourethral, and prostate glands help in the formation of sperm in males.

Coitus: During this semen from a male is ejaculated into the vagina of a female with the help of erectile penis.

The semen then passes through the cervix to reach the uterus.

Fertilization: Four events take place to cause successful fertilization; sperm preparation (capacitation followed by acrosomal reaction), binding, a fusion of plasma membranes of sperm and egg, cortical reaction and activation of the egg.

Post-fertilization events: The zygote undergoes cleavage process to mature into an embryo.
