- They provide instructions for the processes in the cell.
-They store the energy required by the rest of the membrane to perform its functions.
Answer:
They selectively allow certain particles into and out of the cell
Explanation:
Proteins in the cell membrane allow some particles to enter and exit the cell. This type of passive transport is called facilitated diffusion.
Why don’t animals need cells with walls
Answer:
Animal cells do not have cell walls because they do not need them. Cell walls, which are found in plant cells, maintain cell shape, almost as if each cell has its own exoskeleton. This rigidity allows plants to stand upright without the need for bones .

What can impact the severity of weather disturbances along a weather front?
Answer:
Human activity is causing rapid changes to our global climate that are contributing to extreme weather conditions. When fossil fuels are burned for electricity, heat, and transportation, carbon dioxide, a greenhouse gas that traps solar radiation, is released into our atmosphere.
Explanation:
Climate change influences severe weather by causing longer droughts and higher temperatures in some regions and more intense deluges in others, say climate experts. Among the most vulnerable are communities in exposed mo Extreme weather events can lead to substantial impacts, including loss of life, damages to buildings, agricultural production and natural capital, as well as longer term economic effects.untain and coastal regions.

For humans, linoleic acid is one of the essential fatty acids we must consume. It is plentiful in vegetable oils, and we use it to form compounds involved in immune responses. When it is decomposed through a process called b-oxidation, it produces effectively 27 NADH, 9 FADH2 and 9 ATP in the Krebs cycle, along with 9 FADH2 and 9 NADH as part of the decomposition.
Required:
How many ATP should this produce?
Answer:
18 ATP.
Explanation:
Total 18 ATP are produced because 9 FADH2 are converted into 9 ATP molecules and the earlier 9 ATP molecules are already present in the first b-oxidation process. The first Krebs cycle produces 27 NADH, 9 FADH2 and 9 ATP while on the other hand, the second Krebs cycle produces 9 ATP molecules from 9 FADH2 so total it produces 18 ATP molecules.
Cells that are metabolically active and use a lot of energy: include red blood cells. include white adipose (fat storage) cells. are found in the dermal layer, just under the skin. are densely packed with numerous mitochondria. generally are not found in the human body.
Answer:
are densely packed with numerous mitochondria.
Explanation:
Mitochondria are considered as the energetic centers of the eukaryotic cells. These organelles (mitochondria) produce energy in the form of Adenosine Triphosphate (ATP) through the mechanism of cellular respiration, i.e., mitochondria are the organelles where aerobic phases of cellular respiration occur. In presence of oxygen, mitochondria convert chemical energy obtained from foods to ATP, which is the energy coin that cells use to carry out all their metabolic processes (e.g., reproduction, growth, development, etc). Thus, cells with high metabolic requirements need to have many mitochondria in order to produce more ATP.

You have purified the receptor for a hormone by affinity chromatography. During gel filtration chromatography under native conditions the receptor elutes between pyruvate decarboxylase (250 kDa) and glutamine synthetase (620 kDa). During SDS-PAGE, in the absence of reducing agents, the receptor migrates as a single band of approximately 230 kDa. When SDS-PAGE is carried out in the presence of 2-mercaptoethanol the receptor migrates as two bands of approximately 95 and 135 kDa. Explain this result.
Answer:
the hormone receptor is a heterotetramer composed of two subunits with 95 kDa and two subunits with 135 kDa
Explanation:
In this case, the heterotetramer is composed of two heterodimers, each composed of two subunits that held together by disulfide bonds. These heterodimers bind together through hydrophobic interactions in order to form a tetramer. The Sodium Dodecyl Sulfate (SDS) is a denaturing detergent that dissociates both heterodimers by interfering with hydrophobic interactions that hold heterodimers together. It is for that reason that only a single band of 230 kDa is observed (135 kDa + 95 kDa = 230 kDa). Moreover, 2-Mercaptoethanol breaks disulfide bonds, thereby separating the two subunits in the heterodimer. In consequence, after the use of this chemical compound (2-Mercaptoethanol), two different bands with 135 kDa and 95 kDa can be observed.

What is the relationship between the places where malaria is common and where the sickle cell allele is commonly found?
Answer:
At a global scale, the sickle cell gene is most commonly found in areas with historically high levels of malaria, adding geographical support to the hypothesis that the gene, while potentially deadly, avoids disappearing through natural selection by providing protection against malaria.Nov 2, 2010

Aquifer is the process of seeping of water under the ground.
Answer:
The process of seeping of water into the ground is called infiltration. The groundwater thus gets recharged by this process. At places the groundwater is stored between layers of hard rock below the water table. This is known as an aquifer.
Answer:
Explanation:
An aquifer is an underground layer of water-bearing permeable rock, rock fractures or unconsolidated materials (gravel, sand, or silt). Groundwater can be extracted using a water well. The study of water flow in aquifers and the characterization of aquifers is called hydrogeology.

true or false the typical X shaped chromosomes is the result of DNA replication
Answer:
True
Explanation:
Truly, the typical X shaped chromosomes is the result of DNA replication. When the DNA has replicated, it then condenses and coil into the X-shaped of the chromosome. This then implies that replicated chromosomes take the X-shaped structures seen under a microscope.
When this replication occurs, the chromosome is made of two structures that are identical. They are known as the sister chromatids. These chromatids are actually joined at the centromere.

species.
0-Organism
A
Organism-B
Answer: Click or tap here to enter text.
Answer:
The new modification in Organism B is the tail.
Explanation:
This might indicate that the organism has to sprint in order to catch prey or to get away from predators. The organism is most likely not a prey, since it has sharp teeth, making it a carnivore. The tail helps in stabilizing the animal while running. The animal might have new threats that have developed over the years (like humans).

The Six Kingdoms: Plants, Animals, Protists, Fungi, Archaebacteria, Eubacteria. How are organisms placed into their kingdoms?
Answer:
Organisms are placed into their Kingdoms based on their type of cells, their ability to make food, and the number of cells in their bodies.
Explanation: Hope this helps :)
The kingdom is the taxonomical classification. The six kingdoms are divided and differentiated based on the cell type, cell shape, structure, and similarities.
What is the kingdom?The kingdom is the first level of the taxonomical classification that contains a large number of species and further classifies the organisms based on their similarities and differences. It includes plants, animals, protists, fungi, archaebacteria, and eubacteria.
The species are classified based on the cell structure and their shape that makes them different from each other like the prokaryotes and the eukaryotes. Further, they are classified based on the cell number like single or multi-celled structures.
Then they are differentiated further based on the other characteristics like the cell organelles, cell function, and activities, mode of nutrition, reproduction, and the organization of the body.
Therefore, the kingdom classifies the organisms based on similarities and differences.

Mutation is a natural process that changes a DNA sequence. Most DNA changes Faul in a large areas of the genome that sits between genes, and usually they have no effect. When variation occur within jeans, there is more often a consequence, but even then mutations only really cause death or disease. Mutations also generates new variations that can give an individual A survival advantage.
Answer:
The correct answer is -
1) point mutation
2) deletion
3) inversion
4) frameshift mutation.
Explanation:
Point mutation or substitution mutation is a genetic mutation that takes place when there is a change in a single base nucleotide, it can be replaced with other nucleotides from a DNA or RNA sequence of an organism's genome.
Deletion is a genetic mutation that occurs when there is a loss of a segment of a chromosome. If the particular segment is responsible for an important protein or gene the offspring have to be with one copy only therefore, it is considered a bad mutation.
When there is a reversal of the segment of a chromosome occurs a change takes place in genetic material which is known as the inversion type of genetic mutation.
If any of the above mutations take place including deletion, inversion, replacement or insertion in one or more nucleotides to make a change in the amino acid sequence from the site of mutation forward is frameshift mutation.
