The question is incomplete and the whole question is-
Interbreeding two different species of lovebirds produces offspring unable to build a nest after they mature because they lack the innate knowledge needed to carry the nesting materials. The hybrid offspring do not reproduce, and this limits genetic mixing of the two species. This is an example of:
Answer:
The correct answer is- Hybrid infertility
Explanation:
When members of two different species reproduce and produce offspring, then these offsprings are called hybrid. If the hybrid offsprings are not able to produce viable gamete and do not able to reproduce then this is called hybrid infertility. One of the famous examples is mule produce by breeding between donkey and horse.
So here interbreeding of two species of lovebirds produces offspring that do not reproduce and lack innate knowledge needed to build the nest which limits the genetic mixing between the species due to hybrid infertility.
Answer:
Female cones contain eggs and produce seeds.
Explanation:
Strobiles, also known as cones, are structures commonly confused with flowers, but should not be so named. Found mainly in gymnosperms, strobiles are responsible for the formation of gametes.
Female cones are larger and more complex than male cones. They have egg scales, spiraling around the strobile axis, and these cones produce seeds. At the time of reproduction, the scales of this cone are well separated, ensuring that pollen grains reach the eggs, germinate and produce the pollen tube, which is responsible for bringing the male gamete to the female. It is these strobiles that will house the seed after fertilization.
Answer:
<em>The correct option is A) the carrying capacity of a population</em>
Explanation:
Spatial distribution can be described as how spread out a particular population is. Spatial distribution has three types: uniform distribution, clumped distribution or random distribution. When organisms of a population follow a pattern and are uniformly spread in an ecosystem, it is referred as uniform distribution. When organism of a species exist in specific parts of an ecosystem then they form clumped distribution. In random distribution, organisms of a population exist without any pattern.
Light excites the electrons in chlorophyll a molecules of photosystem 1. As these electrons move to another primary electron receptor, electrons from photosystem 2 replace them.
Therefore the answer is FROM PHOTOSYSTEM 2.
