The cell membrane consists of ONE layer of phospholipids.
A. True
B. False
Answer: Hi there I think That I can help You!!!
The cell membrane contains a phospholipid bilayer, but the terms are not interchangeable. Part of the cell membrane is a phospholipid bilayer, made of two layers of phospholipid molecules. However, the cell membrane also contains other macromolecules like membrane proteins, and carbohydrates.
Explanation: So the correct answer is TRUE! don't forget to ate 5 stars and give brainlist!
The statement "the cell membrane consists of one layer of phospholipids" is absolutely false.
What is a Cell membrane?A Cell membrane may be defined as a type of biological membrane that significantly separates the interior components of the cells from the external environment. It also provides protection to the cell as well as other cell organelles.
A cell membrane is made up of a phospholipid bilayer. This illustrates that the two layers of phospholipid molecules are utilized in order to make an effective cell membrane.
It acts as selectively permeable in nature. The head or polar region of phospholipid is hydrophilic while the non-polar tail is hydrophobic in nature.
Therefore, the statement "the cell membrane consists of one layer of phospholipids" is absolutely false.

A fruit fly of genotype B R/b r is testcrossed with b r/b r. In 84 percent of the meioses, there are no chiasmata between the linked genes; in 16 percent of the meioses, there is one chiasma between the genes. What proportion of the progeny will be B r/b r
Answer:
4 percent (4%)
Explanation:
A single crossover occurs between two (non-sister) chromatids belonging to homologous chromosomes. In this case, 16 percent of the meioses have a single crossover, thereby it will produce 8 percent of the chromosomes with the original (parental) combination in the progeny and the remaining 8 percent should be recombinants. From this result, it is reasonable to conclude that half of these recombinants should be 'Br' (and the other remaining 4 percent should be recombinants 'bR'), and therefore the answer is 4 percent (4%).

precipitation
A. The roots of trees
B. Trees at high elevations
C. Birds that migrate seasonally
D. Plants that grow in lakes or rivers
Answer:
B) Trees at high elevations
Explanation:
The atmospheric conditions and precipitation toxicity is most likely to affect trees at high elevations more so than the other answers.
The tree leaves, which are the main key to the tree's photosynthesis, absorb the oxygen and Co2 from the air, which are converted into nutrients. Without proper nutrients, the trees may die out.

One way to think about the importance of biodiversity is simply to think in terms of natural capital: the roles that genes, species, ecosystems, and ecological processes play in supporting human society and a healthy biosphere. What are benefits provided by biodiversity?
Answer and Explanation:
Biodiversity composes of different species living in a certain restricted area. It is the variability of living beings in a natural environment, involving all the species on the planet and their genetic material. This variety includes all plants, animals, fungus, and microorganisms living in a certain place, their genetic variability, and the ecosystems these species form.
Ecosystems include all the biotic, physical, and chemical components of nature, continuously interacting and depending on each other. The ecosystem is composed of living and non-living things that interact and depend on each other. These are the biotic and abiotic factors.
Biodiversity, in equilibrium with abiotic factors, provides ecosystem services, which are important for the maintenance of all forms of life, including human beings.
Ecosystem services
When talking about ecosystem services, we are referring to the benefits that ecosystems provide us. There are four types of ecosystem services:
Provision or supply:These are the products obtained by nature to be used or consumed, directly or with previous processing. Among them, we might mention food, clear freshwater, fertile soils, geotic materials, raw materials (that can be used for clothing, construction), renewable fuels, biochemical compounds, pharmacological/medicinal resources, among others.
Regulation:Refers to ecological processes that improve life. Among others, we might mention climate regulation, CO² absorption, water purification, air purification, erosion control, natural disaster avoidance such as flooding, soil fertility maintenance, waste recycling, pests/plagues control, etc.
Cultural:Refers to not the material benefits. Ecosystems provide a recreational place or area to spend time and learn. They provide a spiritual/religious space, are a source of inspiration. Ecosystems are cultural patrimony and the source of scientific knowledge.

g In transcription, the 3'-hydroxyl group of the growing RNA strand: Group of answer choices NONE OF THESE binds to the 5' ribose. attacks the outermost phosphorous group of the incoming nucleotide. ALL OF THESE attacks the 5' hydrogen of the incoming nucleotide. interacts with a positively charged metal ion in the active site.
Answer:
attacks the outermost phosphorous group of the incoming nucleotide.
Explanation:
Transcription is the biological process where RNA is formed. As you may already know, RNA is an extremely important nucleic acid for genetic processes and the production of proteins. The transcription has three steps that are called start, elongation and end. In the elongation phase, the RNA strand is growing, at this time, RNA polymerase, which is the enzyme responsible for RNA elaboration, places the nucleotides, in the RNA strand, in the 5' - 3' direction. This enzyme causes the hydroxyl, which makes up the nucleotide at the 3' end of the forming RNA, to attack the phosphorus present in the incoming ribonucleotide.
* Identify the organelle that makes energy for the cell
O Nucibus
O Mitochondria
O Golgi Apparatus
O Cell Membrane
Answer:
O Mitochondria
Explanation:
Answer:
b
Explanation:
The mitochondrion (plural mitochondria) is a membrane-bound organelle found in the cytoplasm of eukaryotic cells. It is the power house of the cell
The enzyme dihydrofolate reductase (DHFR) normally resides in the cytosol, and it can be imported into mitochondria by appending a mitochondrial signal sequence. However, when this modified DHFR is incubated with methotrexate, which is a substrate analog that binds tightly to the active site, the modified DHFR is no longer imported. Propose an explanation for this finding.
Required:
a. Consider a transmembrane protein that spans the inner nuclear membrane. Suggest a pathway by which such a protein could reach its destination.
b. Clathrin can assemble with multiple types of adaptors to create coated vesicles. Explain why this multiplicity of adaptors is useful to the cell
Answer:
Within the mitochondria, the import takes place post-translationally. The imported protein must be in an unfolded condition so that it can go through the mitochondria's import machinery. In the existence of methotrexate, the bound DHFR moiety remains in the folded state, and thus, stays on the surface of mitochondria.
It is witnessed that the presequence must be of the length of 55 amino acids to cover both the membranes of mitochondria and must be of about sixty amino acids length to associate with the mhsp70. If the presequence of this methotrexate bound DHFR is of seventy-five amino acids in length, it can associate with mhsp70 within the matrix, to initiate the ATP reliant import within the mitochondria. Due to the presence of various endocytic and intracellular sorting signals, multiple adaptors are essential.

Answer:
convention cells
Explanation:
In the field of fluid dynamics, a convection cell is the phenomenon that occurs when density differences exist within a body of liquid or gas. These density differences result in rising and/or falling currents, which are the key characteristics of a convection cell. When a volume of fluid is heated, it expands and becomes less dense and thus more buoyant than the surrounding fluid. The colder, denser part of the fluid descends to settle below the warmer, less-dense fluid, and this causes the warmer fluid to rise. Such movement is called convection, and the moving body of liquid is referred to as a convection cell. This particular type of convection, where a horizontal layer of fluid is heated from below, is known as Rayleigh–Bénard convection. Convection usually requires a gravitational field, but in microgravity experiments, thermal convection has been observed without gravitational effects.
