The primary mode of reproduction that separates flowering plants from non-flowering plants. While non-flowering plants need on dispersion to continue their life cycle, flowering plants depend on pollination for reproduction.
What is flowering plants and non-flowering plants?Seeds that are protected by a flower or fruit are used by flowering plants to reproduce.
Conifers, ferns, and mosses are examples of non-flowering plants. Conifers produce seeds in cones to reproduce. Spores are used in fern and moss reproduction.
The reproductive organs of plants, called flowers, transport both male and female gametes.
These flowers bear fruits once fertilised. Non-flowering plants are ones that reproduce by spores but don't produce flowers.
Plants differ in appearance, but they always share three characteristics: they are multicellular; they can produce their own food; and they are green.
Thus, these are some similarities between the major stages in the life cycles of flowering plants and non-flowering, seed-bearing plants.

During childbirth, a hormone produced by the pituitary gland causes muscles of the mother's uterus (or womb) to contract. The more contractions there are, the more hormone is produced.
Which best explains why this occurs?
A. Positive feedback is used to build more contractions.
B. Positive feedback is used to lessen the effects of the contractions.
C. Negative feedback is used to build more contractions.
D. Negative feedback is used to lessen the effects of the contractions.
Answer:
Positive feedback is used to build more contractions.
Explanation:
Positive feedback mechanism in humans is also observed during childbirth which is induced by the pressing of the ovarian wall by the baby.
The pressing sensation is passed to the brain via different nerves, and in response, the brain stimulates the pituitary to produce oxytocin.
Oxytocin is responsible for the contractions of the uterine muscles which cause the movement of the fetus towards the cervix, further increasing the stimulus.
The positive feedback loop continues until the baby is born.

What are the phenotypic ratios of a white-eyed female is crossed with a red-eyed male
Answer:
We need to cross a white eyed female (XwXw) and red eyed male (XRY).
The cross can be shown as:
Xw Xw
XR XRXw (female, red eyed) XRXw (female, red eyed)
Y XwY (male, white eyed) XwY (male, white eyed)
Thus, in the offspring we will have the following phenotype:
Males: White eyed.
Females: Red eyed.

Natural selection is the process of small genetic variation in organisms leading to the gradual development of a species.
What is natural selection?"It is the process whereby organisms better adapted to their environment tend to survive and produce more offspring."It depends on the environment and genetic variation.Genetic variation is the changes in the genome.This will result in offspring with different characteristics that their parent species.As time passes this will lead to the development of new species.Hence, the correct answer is: variation.

Macroinvertebrates are organisms that are large (macro) enough to be seen with the naked eye and lack a backbone (invertebrate). They inhabit all types of running waters, from fastflowing mountain streams to slowmoving muddy rivers.
Answer:
I think it's C. it's sexual reproduction because the sperm and egg is comming from two different salamanders, not the same one. Since the egg and sperm are from different salamanders then there will be genetic variation in the offspring because the DNA from two different salamanders are present in the offspring.
