Question:
The macromolecules depicted in the image below make up a wall that surrounds the
outside of all cells. What type of macromolecule is pictured below?
a. Triglycerides
b. Nucleic Acids
C. Steroids
d. Phospholipids
Answers
Answer:
A
Explanation:
There was no picture but the cell membrane does surround the cell and it is a phospholipid bilayer made of triglycerides so it is answer choice A
Phospholipids disposed in a lipidic bilayer compose the cell membrane. Their hydrophilic heads are facing the exterior, and hydrophobic tails facing the interior. The answer is d. Phospholipids.
MEMBRANE COMPOSITION
The cell membrane is composed of two lipidic bilayers, cholesterol, proteins, and glucans incrusted in between.
⇒ LipidsPhospholipids are amphipathic molecules.They have hydrophilic heads facing the exterior and the interior of the cells and hydrophobic tails that arrange against each other in the interlayer space.Lipids can easily change places with other lipids by lateral diffusion in the same layer.They can diffuse transversally to the other layer but not as easily as lateral diffusion.There are also other lipidic movements as rotational diffusion that imply the rotation of the molecule.⇒ CholesterolThese molecules are incrusted in the membrane between the hydrophobic tails of lipids.
⇒ ProteinsAmong the proteins, we can find integral proteins and peripheric proteins.

C.
burn all the residue
D.
mix the residue with raw material to produce more sugar
Answers
Matt can convert the residue into bioethanol .
The correct option is B.
Explanation:
The starchy residue of the sugar can be fermented to alcohols as bioethanol to be used as fuel.
The fermentation process is carried out by bacteria Saccharomyces cerevisiae in anaerobic conditions.
In the process of fermentation of starchy residue apart from bioethanol some medical useful compounds and alcholol derivatives were also obtained as by products.
Though used as fuel it has lower energy than gasoline.
Bioethanol is a biodegradable and non-toxic fossil fuel.
The biomass waste of sugar industry is used for making fuel as bioethanol.

Answers
Answer: A, Creation of new jobs and technology
Explanation:
Global warming can be define as the increase in global temperature which occurs due to increase in abundance of greenhouse gases such as carbon monoxide, carbon dioxide, methane and others. These gases are capable of absorbing the heat energy from sunlight. Hence, makes the atmosphere hot.
The industries may be concerned about the global warming as they they have to find out alternative which can lead to decrease the emission of the pollutants into the atmosphere as the industries may emit poisonous gases during production of goods result due to the use of fossil fuels.
The industries have to create new jobs and technology. As employs like scientists and engineers can provide better alternatives for the source of energy instead of the use of fossil fuels.
Final answer:
Legislation on global warming may lead to the (option a) creation of new jobs and technology as industries innovate to comply with environmental regulations, particularly in the field of renewable energy.
Explanation:
Studies have determined that legislation on global warming can have various effects on industry. One of the ways is a (option a) creation of new jobs and technology. For example, as industries seek to reduce their greenhouse gas emissions in line with legislation, this can lead to innovation and the development of new technologies, such as wind power generation and high-efficiency natural gas systems. These advancements, in turn, can contribute to the creation of jobs in new sectors that are dedicated to sustainable practices and renewable energy solutions.

Answers
Transmission modes of diseases include airborne, fomites, food-borne, insect vectors, and blood-borne. These methods span inhalation of pathogens, contact with contaminated objects, ingestion of tainted food, disease spread by insects, and transmission through blood or body fluids.
Explanation:The modes of disease transmission that apply from the options provided include airborne, fomites, food-borne, insect vectors, and blood-borne transmission.
Airborne transmission occurs when pathogens carried in droplets are expelled during coughing or sneezing and then inhaled by others.Fomites are objects or materials likely to carry infection, such as clothes, utensils, and furniture, that can indirectly transfer pathogens.Food-borne transmission happens when pathogens are ingested through contaminated food.Insect vectors transmit diseases by carrying pathogens from one host to another, either through mechanical transfer or as a host themselves.Blood-borne transmission occurs when pathogens are spread through contact with infected blood or bodily fluids.Which processes happen in the kidney?

the law of independent assortment states that two alleles of the same genes will segregate from each other during gamete formation
TRUE OR FALSE
Answers
Answer: False.
Explanation:
This law states that alleles from two or more DIFFERENT genes will get sorted into gametes independently from one another.
The law of Independent assortment does not stated two the two alleles of the same genes will segregate from each other during gamete formation. Thus, the given statement is false.
What is Law of Independent Assortment?
Mendel's law of independent assortment states that the alleles of different genes in an organism gets sorted out into different gametes independently of one another. In other words, it can be described as the allele a gamete receives for one gene in an organism does not influence the allele which is received for another gene in that organism.
Independent assortment is important because it is responsible for the production of new genetic combinations or recombination in the organism along with the event of crossing over during meiosis. Thus, it contributes to genetic diversity among a population.

Sedimentary rocks form when sand, mud, and pebbles create layers on top of each other. The pressure builds as each layer is added and eventually the layers turn into rock. What role does energy play in the formation of sedementary rock
Answers
Answer:
Energy from the Sun creates the cycle of rain and wind that causes erosion to produce sedimentation.
Explanation:
Sedimentary rocks form through the energy-intensive processes of weathering, erosion, compaction, and cementation, where layers of sediments are transformed into rock as they are buried and pressure increases.
Explanation:The formation of sedimentary rocks involves energy primarily in the form of mechanical and chemical weathering, erosion, and the compaction and cementation processes. Weathering breaks down pre-existing rocks, and the particles are transported by energies such as wind and water currents. As these sediments accumulate, the weight of the overlying material increases the pressure, reducing the space between sediment particles (compaction).
The final step includes cementation, where minerals precipitate from the water being squeezed from the pores, acting like glue to bind particles together to form solid rock. These rocks, such as conglomerate, sandstone, and shale, store not only geological history but also natural resources vital to humans such as fossil fuels.

Answers
Answer:
The blood moves through the cells of the body delivering oxygen.
The blood moves through progressively smaller blood vessels.
The blood removes carbon dioxide and other wastes from the cells.
Explanation:
After leaving the heart, blood moves through progressively smaller blood vessels, delivering oxygen to cells and removing wastes, before returning to the heart.
Explanation:After blood leaves the heart through the aorta, it moves through progressively smaller blood vessels called arterioles and then into even smaller vessels called capillaries. As the blood moves through the capillaries, it delivers oxygen to the cells of the body and removes carbon dioxide and other wastes from the cells. This process is known as gas exchange. The blood then continues its journey through larger vessels called venules and veins, eventually returning to the heart.
