Answer: 1. a. logistics model of growth

2. a. environmental conditions

3. b. all limiting factors

4. b. water availability

Explanation:

1. a. logistic model of growth will show the increase in population of a species in accordance with the carrying capacity exponentially but when the population will experience the scarcity of resources it will decline considerably.

Carrying capacity is the total number of members of the population of a species that an ecosystem can sustain by providing resources.

2. b. All environmental conditions which favor the survival of the living beings will contribute to the carrying capacity for example food, water, shelter, and other resources.

3. b. Limiting factor is the one which limit the chances of survival and growth of a particular species in an ecosystem. For example, scarcity of food, here food is the limiting factor.

4. d.  A density dependent limiting factor is the one which affects the population of the species based upon the density. The water availability is a density dependent limiting factor because the more the density or abundance of a population more will be the scarcity of water as it will be required by all organisms. So, the species population may experience decline due scarcity of water.

When a neuron responds to a particular neurotransmitter by opening gated ion channels
Volgvan

The given question is incomplete. The complete question is:

Question:  When a neuron responds to a particular neurotransmitter by opening gated ion channels, the neurotransmitter is serving as which part of the signal pathway?

A) relay molecule

B) transducer

C) signal molecule

D) response molecule

Answer:

C) signal molecule

Explanation:

Signaling cells produce specific chemicals or compounds called signaling molecules. These signaling molecules arrive at their target cells and bind to the cell surface or intracellular receptors. Binding of the signaling molecules to their receptors present on the target cells is followed by signal transduction and production of desired response by the target cells.  

Neurotransmitters serve as signal molecules that bind to the receptors present on the membranes of the postsynaptic neurons to bring about changes in the membrane potential. Their binding may trigger the opening of the gated ion channels resulting in a change in the membrane potential followed by generation of inhibitory or excitatory responses.

All animals in phylum chordata share which of the following features?
Klio2033 [76]

Answer:

All animals in the phylum Chordata share some key features that appear at some stage during their development 1) notochord 2) dorsal hollow nerve cord 3) pharyngeal slits

Explanation:

Phylum chordata is probably the most notable phylum.The most distinguishing character that all animals belonging to this phylum have is the presence of notochord. Phylum Chordata is again divided into three subphyla. They are:

Urochordata

Cephalaochordata

Vertebrata

Chordates show following features, at different stages in their life. They are:

Notochord: It is a longitudinal rod that is made of cartilage and runs between the nerve cord and the digestive tract. Its main function is to support the nerve cord. In Vertebrate animals, the vertebral column replaces the notochord.

Dorsal Nerve Cord : This is a bundle of nerve fibres which connects the brain to the muscles and other organs.

Pharyngeal slits: They are the openings which connect the mouth and the throat. These openings allow the entry of water through the mouth, without entering the digestive system.
