Answer:
The correct answer is - a positive feedback loop
Explanation:
Oxytocin is a peptide hormone that is released during labor in women which contracts the uterus and n increase of the oxytocin causes more release of oxytocin hormone to increase the contraction more strongly.
Oxytocin shows a positive feedback loop as its release leads to more of the oxytocin release by stimulates its more release. Most of the hormones show negative feedback release.

Hemophilia is a sex-linked, recessive trait. Which of the following describes the probability of hemophilia in the offspring of a man who does not have hemophilia and a woman whose father is a hemophiliac?
Group of answer choices
Each of their sons will have hemophilia
None of their daughters will have hemophilia
Their sons have a 25% chance of having hemophilia
There is a 50% chance that their daughters will have hemophilia
None of the daughters from the union will have hemophilia.
Inheritance pattern of hemophiliaThe woman would be a carrier since she must have inherited the allele from her father. Thus, her genotype will be [tex]X^HX^h[/tex] assuming the H (h) represents the allele.
The genotype of the father will be [tex]X^HY[/tex]
Crossing the two: [tex]X^HX^h[/tex] x [tex]X^HY[/tex]
[tex]X^HX^H[/tex] [tex]X^HY[/tex] [tex]X^HX^h[/tex] [tex]X^hY[/tex]
Thus, none of their daughters will have hemophilia.

2)It didn't explain how continents fit together.
3)It didn't have a mechanism for how drift occurred.
4)It wasn't supported by fossil evidence.
Answer:
It didn’t have a mechanism for how drift occurred.
Explanation:
He couldn't explain the mechanism behind the movement of the Earth's continents.
Wegener's theory of continental drift was almost completely discarded because it didn't have a mechanism for how drift occurred (Option 3).
What is continental drift?The theory of continental drift was proposed by Alfred Wegener to explain the current position of the continents.
According to this theory (continental drift), continents once formed a super landmass called Pangea.In conclusion, Wegener's theory of continental drift was almost completely discarded because it didn't have a mechanism for how drift occurred (Option 3).

Describe the sun’s role in the sustainability of the Earth’s environment.
Without the sun, most/all life would cease to exist, especially once depending on light energy from the sun like plants, forming the bases of life.
Explanation:
Plant (producers) use light energy to photosynthesis, producing the energy or food other herbivores (plus, our primary&secondary consumers) dependant upon, to survive; then, they get preyed upon (by our tertiary consumers) - structuring the food chain as we all know of. Hence, sustaining life/ living organisms on earth, for generations to come.
Thus, all life on earth as we know it, basically, won't exist. Abiotic factors are the one's to live a happy ever after. There are non-living, once that don't undergo cellular respiration like us humans, e.g., rocks don't respire.
Anyways the sun is a star, one day (millions to billions years onwards) it's predicted to engulf our earth, when transitioning to become a red giant. So, it might not sustain earth forever.
Don't panic, you won't live to experience this! How fantastic does this sounds?

Look at the diagram. Seed 1 dispersed by the ______. Which one word completes the sentence
Seed 1 dispersed by the wind and water.
Why are seeds dispersed?Dispersal of seeds is very important for the survival of plant species. If plants grow too closely together, they have to compete for light, water and nutrients from the soil. Seed dispersal allows plants to spread out from a wide area and avoid competing with one another for the same resources.
Wind, water, gravity, ballistic (where the seeds are ejected by forceful and often explosive mechanisms) and animals are the main ways seeds are dispersed.
Drop and roll – the casing of the fruits from trees, such as horse chestnut, split when they land on the ground. On impact the fruit then rolls away from the tree.
