What are the main components of cellular membranes
Answers
Answer:
Cell membranes are composed primarily of fatty-acid-based lipids and proteins. Membrane lipids are principally of two types, phospholipids and sterols (generally cholesterol).
Answer: Phospholipid bilayer with proteins embedded throughout.
Explanation:
This is what I was though in bio. The cell membrane is made up of two layers of phospholipids, which are phosphate heads with fatty acid tails. Embedded in between are proteins, and on the outside are carbohydrate chains.

True or False: Sensory nerves contain only long axons.
Answers
Answer:
False
Explanation:
False. Sensory nerves contain both long and short axons.
What are sensory neurons?Sensory nerves contain both long and short axons. Sensory neurons receive information from sensory receptors in the peripheral nervous system, and these neurons can have both long axons that transmit signals from the periphery to the central nervous system, and short axons that relay signals within the peripheral nervous system.
The length and type of axon in a sensory neuron depends on the specific function of the neuron and the location of the sensory receptor it serves.

Which molecule made during photosynthesis is the best source for carbon and hydrogen atoms used for cellular activities?
O carbon dioxide
O oxygen
O sugar
water
Answers
Answer:
carbon dioxide
Explanation:
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.

The only land available near residential areas is a forested wetland that supports a variety of species. What is a political consequence of not using the land for a new hospital?
Emergency care is farther away, risking the health and well-being of a growing community.
Preserving the ecosystem may upset residents in a community with a hospital shortage.
If there are fewer hospitals, it can slow down the number of new medical career opportunities.
It protects the lives of species and prevents a reduction in carbon sequestering by the trees.

A political consequence of not using the land for a new hospital is that preserving the ecosystem may upset residents in a community with a hospital shortage.
A very important consideration when citing infrastructure is the environmental impact of such projects. This is because, infrastructure is built on land at the expense of the ecosystems that survive in such habitat. Building the said hospital is going to have the negative impact of decrease in biodiversity.

Answer:
I believe it is there first answer.
Oil can go through biomagnification in the food chain is an incorrect description of oil and its impact on the environment. So, the correct option is (C).
What is Oil and its effects in the environment?The oil contains many different toxic compounds that can cause serious health problems such as heart damage, stunted growth, immune system effects and even death.
Oil and gas drilling has serious impacts on our wildlands and communities. Operating round-the-clock drilling projects is causing pollution, fueling climate change, disrupting wildlife and damaging public lands that were set aside for the benefit of all people.
Many other environmental impacts include the greenhouse effect, acid rain, poor water quality, groundwater contamination, among others, which may contribute to the loss of biodiversity as well as the destruction of ecosystems.

Height in humans of polygenic traits with a distribution similar to the graph shown each is true concerning the distribution of heights in human populations?
Answers
Answer:
A polygenic trait is one whose phenotype is influenced by more than one gene. Traits that display a continuous distribution, such as height or skin color, are polygenic. The inheritance of polygenic traits does not show the phenotypic ratios characteristic of Mendelian inheritance, though each of the genes contributing to the trait is inherited as described by Gregor Mendel. Many polygenic traits are also influenced by the environment and are called multifactorial.Explanation:

Enhanced Greenhouse effect
Explanation:
took the quiz and got it right
When heat-absorbing gases increase in the atmosphere, it leads to a phenomenon known as the enhanced greenhouse effect. The correct option is b.
What is the greenhouse effect?A process is known as the “greenhouse effect” makes the earth's lower atmosphere a habitable habitat. Some gases, referred to as greenhouse gases, are capturing the infrared radiations that the sun emits throughout this process.
These solar rays are extremely dangerous and if they enter the earth's atmosphere, they could spread dangerous diseases. Nitrous oxide, carbon dioxide, methane, water vapor, and ozone are examples of greenhouse gases.
The greenhouse effect is affected more by other gases, including ozone, carbon dioxide, methane, nitrogen oxide, and water vapor.
Therefore, the correct option is b, enhanced greenhouse effect.

Dr. Jekyll isolated a mutant yeast cell that contained histone resistant to acetylation. What phenotype will be in those cells
Answers
Explanation: I just took the test.
According to the scenario, the mutant phenotype will definitely express a low level of gene expression.
What is meant by Phenotypes?The phenotype may be defined as the expression of genotypes in the form of traits. In a more simple sense, phenotypes may be characterized as the morphology or physiology which comes due to the combination of alleles.
The acetylation of histones leads to epigenetic modification through which the architecture of chromatin and the regulation of gene expression are controlled by chromatin structure. But when the mutant cells are resistant to these histone acetylations, it will eventually lower the gene expression through which normal functions so the gene must be affected.
Therefore, the mutant phenotype will definitely express a low level of gene expression.
