Answer:
Ectoderm
Explanation:
Of the three primary germ layers in the very early embryo, the ectoderm is the one that gives place to the epidermis (epidermic skin cells).
The mesoderm will develop into muscle and bone, while endoderm turns into the lungs, stomach and other organs.
The total population change of this seal population is 780.
<h3 /><h3>What is Population change?</h3>
Population change refers to the difference in size of a population over a
given period of time which is usually one year.
Population size = 2,000
Offspring= 950
Death = 150
Immigration= 30
Emigration= 50
Population change+ Offspring + Immigration - Death - Emigration
2000+ 950+ 30 - 150 - 50 = 2,780
Population change= Final population- Initial population
=2780 - 2000
=780

Explanation: Diets high in red meat, dark leafy vegetables, dried fruits and nuts, iron-fortified cereals, or bread can help treat or prevent iron deficiency.
Complete answer:
You will find the table that provides data about the two species in the attached files.
Answer:
Because in the table provided you can see that, even when both species can use the same resources, certain vegetable species are eaten only by buffalo and not by cattle, while some other plants are eaten by cattle and not by buffalo.
Explanation:
The realized niche refers to the restricted conditions in which a species can live and survive as a result of environmental physic characteristics and the <u>interaction with other species</u>.
The competitive exclusion principle establishes that two or more species that share the same niche requirements and are in biological competition for the same resources, won´t be able to coexist indefinitely in the same space if the other ecological factors are constant. When the superior competitor occupies entirely the inferior competitor´s fundamental niche, the superior species has advantages over the other species and monopolizes all the resources. At this point, the inferior species is displaced and must adapt to use other resources changing its behavior, or must migrate to another area where it can get access to its needs, or get extinct.
Resources partitioning refers to one dominant species monopolizing the resources, and the other inferior species use other resources -partially or completely-, migrate or get extinguished. A way in which species can divide resources is by living in different habitat areas. These species might eat the same food, and can roost in different places within the habitat. This resource partitioning and differentiation in the function of their physical location allows both species to coexist more effectively.
In the exposed example, cattle and buffalo share the same fundamental niche, meaning that both of them can consume the same vegetable species, although in some cases, cattle eat certain species that buffalo does not, and vice-versa. Probably it occurred <u>resource partitioning</u> between these species, reflected in the fact that buffalo feeds on some species, while cattle feed on some other species.
Answer:
Biofuels have been around longer than cars have, but cheap gasoline and diesel have long kept them on the fringe. Spikes in oil prices, and now global efforts to stave off the worst effects of climate change, have lent new urgency to the search for clean, renewable fuels.
Our road travel, flights, and shipping account for nearly a quarter of the world's greenhouse gas emissions, and transportation today remains heavily dependent on fossil fuels. The idea behind biofuel is to replace traditional fuels with those made from plant material or other feedstocks that are renewable.
But the concept of using farmland to produce fuel instead of food comes with its own challenges, and solutions that rely on waste or other feedstocks haven't yet been able to compete on price and scale with conventional fuels. Global biofuel output needs to triple by 2030 in order to meet the International Energy Agency's targets for sustainable growth.
