Answer:
DNA unzips between base pairs.
Explanation:
This is the first step of protein synthesis.
The first step of protein synthesis is attachment of mRNA to ribosomes. Option A is correct.
Protein synthesis:
It is known as translation. In this mRNA is translated in to the sequence of amino acids which ultimately form protein.
First mRNA attach to ribosome,tRNA bring amino acid to ribosomes and attach to mRNA.Amino acids bond together via peptide bond.Therefore, the first step of protein synthesis is attachment of mRNA to ribosomes.

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.

what is the differences between boiling and autoclaving
Explanation: Water baths reach a maximum boiling point of 100°C (212°F). Autoclaves ideally operate at higher temperatures of 120°C (284°F) and can go as high as 133°C (273 °F) Boiling in a water bath can take an hour or longer for effective sterilization to be achieved.

Drag each resource to its mining type. Answers may be used more than once. (2 points)
aluminum
tin
copper
Choices are
1. underground
2. open pit
3. placer
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.

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
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.

hypothesized that chloroplasts are what help plants
make food. After many more observations of all types of
plants and animals, scientists are convinced today that
chloroplasts make food for plants.

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

Which statement is false?Orthologs are homologs found in the same species.The function of a protein is a result of its amino acid sequence.Protein structure is commonly described at four levels.It is possible to change the amino acid sequence of a protein and have no effect on its functio
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.

B-cells do which of the following things?
a. Make antibodies
b. Inhibit Function of other T-cells and B-cells
c. Stay in circulation to speed up response to an antigen the next time
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
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.
