During exercise, muscle cells release the protein ________ which can cause brite/beige adipocyte formation:
shepuryov [24]

Answer: Option "D".

Explanation: During exercise muscle cells release irisin protein is being released causing Beige adipocyte formation.

the secretion of Irisin leads to the improvement in muscle activity, bone mineral density, increasing the formation of brown like Beige adipocytes in the tissue.

Adipocytes are divided into two tissues namely white and brown. white tissues generally expand during excessive nutrition and brown adipocytes have mitochondria and burn the energy during exercises resulting into the break down of ATP  molecules increasing the body heat.  

Therefore, during exercise heat generated due to the formation of brown adipocyte tissue which are formed due to the release of irisin protein.

When cells communicate by the signaling process, one cell produces a _________________BLANK that must be received by the _______
velikii [3]

Answer:

1. Signaling molecule

2. Signaling receptors

Explanation:

Hormones, growth factors, neurotransmitters, etc. serve the function of signaling molecules for cells. These molecules are released by one cell and bind to the receptors present on/in the target cells to elicit the desired response. Thereby, the signaling molecules serve in cell-cell communication.

For example, insulin hormone synthesized and released from beta cells of pancreas binds to its cell surface receptors present on the surfaces of liver cells and muscle cells to stimulate the uptake of the glucose from the blood.  

Likewise, neurotransmitters released from the presynaptic neuron bind to receptors present on the membrane of postsynaptic neuron and serve to carry the nerve impulse to the postsynaptic neuron.

What is the key adaption of angiosperms that allowed these plants to dominate the landscape?
maria [59]

The  key adaption of angiosperms that allowed these plants to dominate the landscaper is flowers

<h3>What is the most important adaptation of angiosperms?</h3>

Angiosperms initially appeared in the late Cretaceous Period, between 125 and 100 million years ago.

Flowers and fruit were developed by angiosperms to draw pollinators and protect their seeds, respectively.

Flowers come in a variety of shapes, sizes, and scents that are all designed to entice pollinators.

An egg that has been fertilised grows into a seed that is protected by a fleshy fruit.

Throughout the Mesozoic period, numerous contemporary insect groups developed alongside angiosperms, including insect pollinators that supported angiosperm growth; in many cases, flowers and their pollinators coevolved.
