Transmembrane proteins allow large particles to pass through the membrane. (a) True
(b) False

Answers

Answer: True

Explanation:

A trans membrane protein is a type of integral membrane protein that is found on the whole cell membrane.

A trans membrane protein function as the gateway and allows the movement of specific molecules or substance across the membrane.

The larger molecules which cannot travel across membrane is transported with the help of trans membrane proteins.

hence, the given statement is true.

In humans, one function of the skin is to prevent water loss. Skin releases water or holds in water when necessary.Which two structures in plants have a similar function to skin?

> roots and chloroplasts

> phloem and roots

> cuticle and stomata

> stomata and phloem

Answers

Cuticle and stomata in plants have a similar function to skin.

What are the functions of cuticles?

The cuticle is well known for its functions as a diffusion barrier limiting water and solute transport across the apoplast and for its protection of the plant against chemical and mechanical damage, as well as pest and pathogen attack.

In some higher plants, the cuticle is a water-impervious protective layer covering the epidermal cells of leaves and other parts and limiting water loss. It consists of cutin, a waxy, water-repellent substance allied to suberin, which is found in the cell walls of corky tissue.

The cuticle itself comprises three layers: the cuticular layer; cuticle proper; and epicuticular waxes. The cuticular layer is the innermost layer, which overlays the primary wall and consists of cellulose and other polysaccharides along with cutin and wax.

Which process occurs when bacteria converts nitrogen gas to a usable form?decomposition
condensation
fixation
transpiration

Answers

A biological process which occurs when bacteria converts nitrogen gas (N₂) into a usable form for living organism is called: C. fixation.

What is fixation?

Fixation can be defined as a biological process which occurs when nitrogen gas (N₂) is converted by the bacteria found within the soil, into a usable form for living organism.

This ultimately implies that, a bacteria provide the essential nutrients for living organism such as green plants by converting nitrogen gas (N₂) into a usable form.

The information in neural transmission which always travels in one direction in the neuron first goes through the ____________.

Answers

Answer: Sensory neuron

The information in neural transmission which always travels in one direction in the neuron first goes through the sensory neuron

Explanation:

The sensory neuron transmits impulses from the sensory cell or receptor towards the central nervous system (spinal cord and brain). From there they are relayed to the intermediate neuron, before being transferred to the motor neuron that brings about a response.

See the chart below

Sensory neuron ----> Intermediate neuron ----> Motor neuron

Final answer:

In neural transmission, information first goes through the dendrite of a neuron, converting chemical signals into electrical impulses. These impulses then travel to the axon and finally, the axon terminals. The unidirectional flow of these signals ensure clear and constant transmission of messages.

Explanation:

The information in neural transmission that always travels in one direction in the neuron first goes through the dendrite. The dendrites are specialized to receive chemical signals from the synaptic cleft which are then converted into electrical signals.

From there, the electrical impulses (or action potentials) flow through the neuron, to the axon and finally to the axon terminals, where the signal is ready to be transmitted to the next neuron via neurotransmitters.

This unidirectional flow of information ensures that messages are transmitted in a clear and consistent manner throughout the neural network.
