Answer:
Epithelial tissue
Explanation:
Functions of epithelial cells include secretion, selective absorption, protection, transcellular transport, and sensing. Epithelial layers contain no blood vessels, so they must receive nourishment via and diffusion of substances from the underlying connective tissue, through the basement membrane.
<span>The third option is correct, seed coat, stored food, embryo. The coat is what protects the inner parts from outside infuences, while the food is the nutrients that the seed uses when growing and developing. The embryo will eventually become the new plant that grows out of the seed. Seeds usually fall from things like pinecones on the ground near the original tree, which is why coniferous forests are usually very dense.</span>
<u>Answer:</u>
<em>Climate change positively affects organisms by </em><em><u>providing them new habitat.
</u></em>
<u>Explanation:</u>
Climate change induces <em>changes in various parameters of an ecosystem </em>like temperature, precipitation, soil properties etc. habitats may undergo changes that make it unsuitable for native organisms to live in.
But this <em>new conditions</em> may be favourable for some other kind of organisms to thrive and flourish.
<em>For example, </em>when temperature of a lake increases due to climate change warm water aquatic organisms find a new habitat in the lake. But this threatens the life of <em>native cold water organisms of the lake. </em>
Thus climate change doesn’t bring any benefits to living world without harming one or the other <em>group of organisms.

Answer:
Nile crocodile
Explanation:
The Egyptian plover is a small bird with a very unusual friend in the animal kingdom. This bird actually has a symbiotic relationship with the Nile crocodile. It may seem very odd relationship, but it is one that works excellently for both sides. The crocodiles have sharp set of teeth, but they have spaces between them and can not move their jaws sideways. Because of this, very often there's meat stuck between the teeth of the crocodiles, and this is when the Egyptian plover comes on the scene. This little bird actually gets into the open mouth of the crocodiles, picking up the pieces of meat that have stuck between their teeth, and then continuing with its mission. The crocodiles do not try to eat this bird, but instead they stand still while it does its job. The relationship is beneficial for both sides, as the crocodiles have their own personal ''dentist'', while the plover gets free food.
