Answer:
If the receptor sites for the neurotransmitter are blocked, the neurotransmitter is not able to act on that receptor. Most of the time, the neurotransmitter will then be taken back up by the neuron that released it, in a process known as "reuptake".

What inference can be made from the phylogenetic tree?
Choose 1 answer:
Species A was probably much larger than any of the other organisms.
B
Species G is extinct.
С
Species F and G are more closely related than species B and E.
Species C is the most recent common ancestor of species B and D.
Inference from phylogenic tree is:
Species A was probably much larger than any of the other organisms.
What is phylogenic tree?
A phylogenetic tree, also known as a phylogeny, is a diagram that depicts the lines of evolutionary descent of different species, organisms, or genes from a common ancestor.
What can phylogenetic trees tell us?
A phylogenetic tree can help trace a species back through evolutionary history, down the branches of the tree, and locate their common ancestry along the way.

2. Why can't sea stars live in terrestrial environments?
Due to lack of certain features, sea stars can't live in land environment.
Why can't sea stars live in terrestrial environments?Sea stars can not live in terrestrial environments because of the body structure which is fit for water not land environment. Every organism has special features that allows it to live and survive in that specific environment.
So we can conclude that due to lack of certain features, sea stars can't live in land environment.

How Jackrabbit controls his body temperature through his capillaries?
a. Design a meal that uses four different types of plant foods, two different types
of animal foods, and one food that relies on fungi, algae, or bacteria. How does
the management of natural resources determine whether your meal will be
available? (1 point)
b. If our forest supplies are used up faster than they are replenished, what
products could be missing or hard to get in our society? (1 point)
c. There are many materials humans use that are produced from plant or animal
material. List at least three examples in each box. One square is provided for you.
(1.5 points)
Answer: Humans are dependent on animal and plant based products for survival.
Explanation:
a. Pizza: My meal is pizza which contains the plant and animal based foods. Plant foods include vegetables like tomato, capsicum, corn, and onion. The two animal based foods used in this will be chicken meat and swine meat. The pizza dough requires yeast to attain a desire puff, yeast here is a fungal strain. The resources required for preparation of pizza are easily available as they are replenishable renewable natural resources. These are available in farm, food market, and butcher shops easily. The plant based foods will grow with the help of seeds and animal based food will be available by breeding in farms.
b. The forest reserves are rich source of renewable natural resources like wood, plant based food, medicines, and other products. If forest reserves are not replenished then the need of these products will increase due to scarcity.
c. Plant: Clothes, furniture, medicines, food, and others.
Animal: Clothes (jute, silk), tools from animal horns, decorative item from elephant ivory

As the nutritional energy passes through the food chain, energy......
O a) is gained
b) decreases
c) remains constant
d) increases, then decreases
Answer:
B. Decreases
Explanation:
In an ideal food chain, nutritional energy from producers (plants) are transfered to other animals at different levels on the food chain. As nutritional level is being passed from one level to another, most of the nutritional energy is lost in the process. Therefore, energy decreases as the nutritional energy passes through the food chain.

Model the reflection of a light wave.
1.
Choose a material that will reflect light.
2.
Create a diagram that represents a light wave being reflected.
3. Label your diagram "Light Wave Reflected."
4. Below the diagram, write a brief description of the interaction between the wave and the
material. Be sure to discuss the angle of incidence, the angle of reflection and the normal.
Also explain how the amplitude and frequency of the wave are affected.
When waves of light (and other electromagnetic radiation) come into contact with a surface or other boundary that does not absorb the radiation's energy, the waves bounce off the surface and back into space.
What is Light wave?The simplest instance of visible light reflection is a smooth pool of water's surface, where incident light is orderedly reflected to provide a clear image of the landscape around the pool.
When you throw a rock into a pool, it disturbs the water and causes waves, which prevent reflection by spreading the light rays in all directions.
The incoming light wave is referred to as an incident wave, and the wave that is bounced away from the surface is termed the reflected wave. Visible white light that is directed onto the surface of a mirror at an angle (incident) is reflected back into space by the mirror surface at another angle (reflected) that is equal to the incident angle, as presented for the action of a beam of light from a flashlight on a smooth.
Therefore, When waves of light (and other electromagnetic radiation) come into contact with a surface or other boundary that does not absorb the radiation's energy, the waves bounce off the surface and back into space.

Most successful parasites, such as a cat flea, weaken their host but do not kill it. Why is killing its host usually disadvantageous for a parasite?
Question 4 options:
Relatives of the host would then attack the parasites.
Lysosomes from the host would then attack the parasite.
If a parasite kills its host, it will then have to find a new host in order to survive.
Parasitism is a relationship where both organisms benefit; killing the host is not beneficial to the host.
Answer:
The correct answer is - If a parasite kills its host, it will then have to find a new host in order to survive.
Explanation:
Parasites are organisms that depend on other organisms for their food and energy in order to survive. The organism that they depend on is called their host. In this only parasites get benefitted while hosts are harmed.
Although parasites harm their hosts, parasites tend to not kill the host as its best for them so they do not have to find another host and again establish control on the host's body and body functions, for their survival.

(2)
Coll
19)what is an underground stem
Answer:
Explanation:
This is because ferns are vascular plants i.e they have vascular tissues which are xylem and phloems which help to conduct water and nutrients while mosses are non vascular plants.
2. Ferns sporophytes are differentiated into true leaves, stems and true roots while mosses lack true roots, stems and leaves.
Underground stems are modified part of plants that are derived from stem tissues which grow under the ground. Underground stems grow beneath the soil. Examples include Rhizomes, ginger, tubers e t.c.
