Answer:

Embryological evidence

Explanation:

Deuterostomes is a group that includes echinoderms, hemichordates, and chordates. Although these animals exhibit a wide variety of body plans, they share a mouth secondarily formed during embryo development, which it is believed to be an evolutionarily derived character present between a common ancestor and all its descendants (i.e., a synapomorphy). This oral cavity is formed by the invagination of the ectoderm layer opposite to the blastopore of the gastrula.

For each of the following, circle the word that does not belong belong with the rest and then in ONE complete sentence, explain
Vika [28.1K]

Answer: the words that doesn't belong include:

1.) Power

2.) Deforestation

Explanation:

1.) Coal, Oil, Solar and Natural Gas are considered to be sources of energy while POWER is not considered among the rest this is because it's energy in action and not a source of energy.

Coal, oil and natural gas are known as fossil fuels which are the most common sources of energy in industries and homes. These fossil fuels are destroyed by use, that is, they cannot be recovered. Alternative sources of energy is the solar which is gotten from the sun energy. Although not considered a very efficient energy producer, there are already discovered schemes that would provide us with an inexhaustible supply of energy which would also not cause any pollution problems.

2.) Biodegradable, Recycling and Sustainability are means by which pollution is being avoided in the environment. While DEFORESTATION is a process that can cause pollution of an environment, therefore it doesn't fit into the rest of other words.

Biodegradable materials can be broken down by microorganism. Examples include human and animal excreta. Recycling is the reprocessing of waste materials in order to be re-used. This reduces the amount of waste that are sent to incinerators. While sustainability is the maintenance of the ecosystem to remain diverse and productive over time. This could be seen in the preferred use of renewable energy over non renewable energy. But deforestation is the massive cutting down of trees which can cause soil erosion and climate changes leading to the pollution of the environment.

pashok25 [27]

Most dietary <u>fats </u>are too large to be assimilated and absorbed into the capillaries but they are otherwise absorbed into the lacteals.

<h3>What are dietary fats?</h3>

Dietary fat is necessary for good health. It offers you strength and aids in the absorption of vitamins by your body. Dietary fat has about twice as much energy per gram as carbs and protein.

In the villi ( an organ in the small intestine) is located the lacteal which is a lymphatic capillary that absorbs and assimilates dietary fats. 

Most nutrients are also absorbed through the blood capillaries, but as for dietary fats and fat-soluble vitamins, they are absorbed by the lacteals.
