The antelope and duck have two very different movement mechanics.

The antelope moves by running across the grasslands, and the duck moves by swimming in the pond or walking on the ground.

The antelope and duck have two very different movement mechanics. The antelope moves by running across the grasslands, and the duck moves by swimming in the pond or walking on the ground.

Ecological interactions are the partnerships in between the species in which the organism benefits while the other does not. All the creatures in an environment has been linked in some manner. Originally, populations of the various species interact in the complicated web of the interactions.

The relationships between the species in communities are the crucial in natural selection because they would influence the evolution of the interacting species.

These particular interactions would have the positive, negative, as well as the neutral impact on the capacity of either species to live the life and to perform the process of reproduction, or the "fitness."

Therefore, The antelope moves by running across the grasslands, and the duck moves by swimming in the pond or walking on the ground.

The gradual change in plant communities of a sand dune ecosystem is an example of ecological succesion and can result in greater species diversity.

Ecological succession refers to the gradual changes that occurs in a habitat such that with time new species replace previous species or new species take over an envrionment that had no living organisms initially until a stable community of organisms is established.

There are two types of ecological succession;

Succession results in greater species diversity.

An example of succession is when species of organisms begin to live one previously care area such as in sand dunes.

Answer:

Prokaryotes - smaller, usually bacteria, unicellular, NO membranes

Eukaryotes - HAS membranes, complex organelles, plant/animal cells

Explanation:

Hope this helps!

Eukaryotes has been known as the creatures which are made up of the cells with membrane-bound organelles and the nucleus that contains DNA in the manner of chromosomes. Thus, option B is correct.

Prokaryotes and eukaryotes are the two classes into which all living things may be divided based on the basic makeup of their cells. Prokaryotes - smaller, usually bacteria, unicellular, NO membranes and Eukaryotes has the membranes, and the complex organelles, plant or animal cells.

Prokaryotes are the creatures that consisting of the cells that don't have the cell nuclei or any organelles that are enclosed in the membranes. It follows that prokaryotes' DNA is not contained within a nucleus.

Eukaryotic organisms can have several cells or only one cell. Eukaryotes make up all animal life. Protists, fungi, and plants are examples of additional eukaryotes.

Therefore, Prokaryotes do not have a nucleus, eukaryotes have a nucleus.

If glucose begin to increase after a meal, glucagon levels must decrease while insulin levels must increase in order to maintain metabolic homeostasis.

Homeostasis is the process by which a stable internal environment is maintained irrespective of the changes in external conditions.

The regulation of sugar level in the blood is one of the homeostatic responses. Insulin and glucagon are two hormones used to perform this task of blood sugar regulation.

Therefore, if glucose begin to increase after a meal, glucagon levels must decrease while insulin levels must increase in order to maintain metabolic homeostasis.

In general, excess amounts of water-soluble vitamins are excreted via the urine.

Water-soluble vitamins are generally excreted through the urine. Water-soluble vitamins can easily combine with the urine and be excreted out of the body. Hence, they need to be taken on a regular basis.

Vitamins are necessary for the body as they play an important role in enzyme activity. Fat-soluble vitamins, such as vitamins A, D, E, and K, are present, and water-soluble vitamins, such as the vitamin B complex and vitamin C, are also present. Fat-soluble vitamins can be stored in body fat and used, but water-soluble vitamins can be lost through urine.

Water-soluble vitamins can be gotten from fruits such as oranges, etc. To avoid vitamin deficiency, they should be taken on a regular basis as they are lost. Vitamin C is important for collagen function. Fat-soluble vitamins can be gotten from plants and animals.
