The process by which molecules such as glucose are moved into cells along their concentration gradient with the help of membrane-bound carrier proteins is called The process by which molecules such as glucose are moved into cells along their concentration gradient with the help of membrane-bound carrier proteins is called

Answers

Answer 1

Answer:

Facilitated diffusion

Explanation

Generally when molecules undergo passive diffusion along their concentration gradient,and aided by the cell membrane which provide hydrophillic areas for the molecules to pass through,this is called  facilitate the diffusion.The membrane would be impermeable to these molecules without the proteins,

It is a special transport mechanism for large molecular substances like glucose and Amino acids and ions  e.g Na+ and K+.Therefore facilitated mean to aid,thus the membrane proteins aids or help molecules to pass through.

Channel protein and carrier proteins are the two type of protein involved in the transport.They are specific for each molecules,and would only allow the passage of one molecule or ion through.

Energy is not needed for this to occur place the molecules of glucose are moving along the concentration gradient.

Specifically channel proteins are fixed in shape,some are gated.They are water filled pores Carrier proteins are flexible and adjust their shape to the two media for transport.Thus if the concentration of substances to be transported i s higher on on side A of the cell membrane proteins,the carrier protein will be open to  that side to convey the molecules across.

The amount of molecules transported depend on the amount of the  carries and channel protein available.

3. placer

Answers

Answer:

Aluminium  - Open Pit (or Open Cut Mining)

Tin  - Placer Mining

Copper - Underground Mining

Explanation:

Open Pit Mining: Another name for open pit mining is open-cast or open cut mining. In simple terms, this involves removing topsoil or earth in order to expose and access the minerals beneath them. This type of mining is usually applied when the mineral deposit is close to the earths surface.

A typical feature of open-pit mines is that they leave very wide open pits though the actions of excavators.

Besides Aluminium, other types of minerals which can be mined using this method are: Bitumen, Clay, Coquina etc

Placer Mining

Placer deposits (that is minerals that have been concentrated on a location by weathering are usually accessed by the use of water. This method is mostly connected with the retrieval of minerals within water bodies. Water is used to dig up, and collect heavy minerals from such deposits.

Underground Minning

The entrance into underground mines can be horizontal or vertical.

An underground mine is simply a mine that is beneath the surface of the earth.

Cheers

The extraction of the minerals and the resources from below the earth's surface is mining. Aluminium is extracted by open pit, tin by pacer and copper by underground mining.

What are the types of mining?

Open-pit or Open Cut Mining is the method of Aluminum extraction. The method involves the removal of the topsoil to access the minerals found in the earth layers. This can be done to extract the minerals that are not found too deep in the layers.

In open-pit, open and wide pits are dugged to extract the minerals with the help of the excavators. It can also be used for the extraction of Coquina and clay.

Placer mining is the method that is based on mineral deposition and the process of weathering is used for the removal or the extraction of the minerals from the water bodies in which they got deposited.

Underground mining is the technique of mining that is done for the extraction of minerals by the underground vertical or horizontal portals or openings in the earth.

Therefore, Aluminium will be extracted by option 2. open pit, Tin by option 3. placer and copper by option 1. underground mining.

Sue has Parkinson's disease. She takes medication that increases the level of dopamine in her brain.

What is Parkinson's disease?

It is a neurodegenerative disorder characterized by a loss of dopamine-producing cells in the brain, particularly in an area called the substantia nigra.

Dopamine is a neurotransmitter that plays a crucial role in coordinating movement and regulating various brain functions.

In Parkinson's disease, dopamine deficiency leads to impaired communication between brain cells, resulting in the motor symptoms associated with the condition, such as tremors, stiffness, and difficulty with movement and coordination.

To address this dopamine deficiency, medications known as dopamine agonists or levodopa are commonly prescribed.

These medications work by increasing the levels of dopamine in the brain, compensating for the deficit caused by the disease.

Thus, Sue takes medications that increase the level of Dopamine.

d. Stimulate Function of other T-cells and B-cells
e. Take in and process antigens binding them to MHC protein
f. Attack cells infected by viruses

Answers

Answer:

a. Make antibodies

Explanation:

B-cells is one of the two types of lymphocytes or white blood cells produced in the marrow of the bone (the other being T-cells). B-cells are a part of adaptive or acquired immunity in our body i.e. a learned defense after a pathogen might have penetrated.

B-cells help combat foreign Invaders that make way into the body by producing ANTIBODIES, which are specific to a particular pathogen. Note that, the B-cells learnt to combat based on a previous infection of such pathogen. In response to an antigen, the B-cells produce the plasma cells, which in turn produce the antibodies.

Answers

Answer:

The correct answer is "Orthologs are homologs found in the same species".

Explanation:

Orthologs, or orthologous genes, are defined as genes found in different species that evolved from a common ancestry. Therefore, It is false to affirm that orthologs are homologs found in the same species. Orthologous genes have the same function and often share common nucleotide sequences, however, they must be found in different species to be considered orthologs.

Which is one event that may lead to Primary succession? clear-cutting climate change volcanic eruption introduced species

Answers

Answer:

(c)volcanic eruption

Explanation:

An event that may lead to primary succession is volcanic eruption.

Primary succession happens when pioneer organisms colonize an area that holds no life before. It usually happens when a new land is formed or when a bare rock becomes exposed to life.

When volcanic eruption happens, new rocks are formed from the molten magma and these rocks provide a surface that can be colonized by pioneer species such as lichen.

From there, the successional process continues with time until a stable community is formed, all other things being equal.

Myoglobin transfers oxygen obtained from hemoglobin to mitochondrial proteins involved in the catabolism of metabolic fuels to produce energy for the muscle cell. Using what you have learned in this chapter about myoglobin and hemoglobin, what can you conclude about the structures of these mitochondrial proteins

Answers

Answer:

Both are heteroproteins with a globular structure.

Explanation:

Both proteins are very similar, myoglobin is usually relatively small in size compared to hemoglobin.

Both proteins are considered heterogeneous because they are globular, because of their globular shape and the order of union between their amino acids.

The center of these proteins is iron, which is why they are capable of transporting gases such as oxygen, carbon dioxide (CO) and NO.

The structures that make them up are known as heme groups, these heme groups can also be found in meats of animal origin, it is as well as inside the erythrocyte, there is hemoglobin, which contains the heme group with a divalent iron capable of be oxidized to transport this oxygen in the form of oxide, towards the myoglobin that will receive it in the muscular tissue, and consequently oxygenate the muscular tissues as well as other tissues during locomotion or physical action.

which one of the following processes does not occur to excess neurotransmitters in the synapse

Answers

This question is incomplete because the options are not given; here is the complete question:

Which one of the following processes does not occur to excess neurotransmitters in the synapse?

A. Break down or digested into inactive fragments.

B. Collection by scavenger vesicles left over from the neurotransmitter release.

C. Drifting away from the synapse via diffusion.

D. Reuptake within the pre-synaptic neuron.

The answer to this question is B. Collection by scavenger vesicles left over from the neurotransmitter release.

Explanation:

The word synapse refers to the neurological structure that allows the transmission of signals or information between neurons. This process occurs through neurotransmitters, which are the molecules or substances with the messages.

Moreover, in this process, there can be in some cases excess. In this situation, the body reacts to this excess by degrading or breaking down the extra neurotransmitters, eliminating it through diffusion, or even reabsorbing it (reuptake). In this context, all are processes that occur due to excess neurotransmitters except collection by scavenger vesicles because in most cases neurotransmitters are simply absorbed or eliminated but there are not specialized scavenger vesicles that collect them.
