How would a small, uncharged lipid move across the cell membrane?
o through simple diffusion, down the concentration gradient
O through simple diffusion, against the concentration gradient
o through facilitated diffusion, down the concentration gradient
O through facilitated diffusion, against the concentration gradient
Answer:
Through simple diffusion, down the concentration gradient.
Explanation:
The phospholipids of the membrane are amphipathic with hydrophillic heads and hydrophobic tails. Other polar molecules cannot go through this hydrophobic interior. Since small uncharged lipids are non polar and hydrohobic, they are able to go through the membrane without the help of transport proteins. Therefore, the last two options can be ruled out because facilitated diffusion includes the use of a protein. Diffusion involves molecules moving down the concentration gradient so the second option can be ruled out.

1.) How is Albinism a genetic disorder?
Answer:
1. We commonly know that albinism is a type 1 genetic disorder which is inherently derived from a gene mutation on the X chromosome
2. This can and is sometimes inherited by the offspring by a process known as X-linked recessive inheritance.
3. Hence it abnormally mutates the X chromosome which allows it the characteristic of a genetic disorder

46. A sample of human DNA is made up of approximately 30% adenine. Based on
this information, and the base pairing rules, approximately how much cytosine
found in human DNA?
A 70%
B 20%
C 30%
D 10%
Help please
Answer:
its A/F
Explanation:
A sample of human DNA is made up of approximately 30% adenine. The quantity of cytosine found in human DNA will be 20%. The correct option is B.
What is DNA base pairing?DNA base pairing is the pairing or joining of DNA bases to each other with hydrogen bonds. There are four types of bases present in DNA. They are adenine, thymine, cytosine, and guanine.
Adenine pairs with thymine with double hydrogen bonds and cytosine joined with guanine with triple bonds of hydrogen. The pairing between these base pairs is alternated in the sequence of DNA.
According to the base pairing rule. There will be 100% of these bases present together. So if there is 30% adenine, there will be 30% thymine. The total becomes 60%. Now remain is 40%. So there will be 20 % cytosine and 20% guanine.
Thus, the correct option is B 20%.

What are the four possible gametes of an organism has the genotype KkMm?
Answer:
KM, Km, kM, km
Explanation:
Gametes, which are only produced during sexual reproduction, are formed as a result of meiosis. According to Gregor Mendel in his law of Segregation, alleles of a gene will separate into gametes in such a way that only one form of a gene (allele) will be present in each gamete.
In this question involving a dihybrid with genotype: KkMm, the allele combinations of the gametes that will be produced after meiosis are KM, Km, kM, km.
A dominant allele is often covered up or masked by the recessive allele. True or false?
Answer:
Explanation:In a heterozygote, the allele which masks the other is referred to as dominant, while the allele that is masked is referred to as recessive.
Answer:
If the alleles are different, the dominant allele will be expressed, while the effect of the other allele, called recessive, is masked. In the case of a recessive genetic disorder, an individual must inherit two copies of the mutated allele in order for the disease to be present

Which factor is found in a scientific claim? endorsement by famous scientists data collection from only one facility similar results in multiple tests of the claim identical data across all tests of the claim
Answer:
similar results in multiple tests of the claim
Explanation:
e2020 told me so
Similar results in multiple tests of the claim are a factor found in a scientific claim.
What is a scientific claim?The statements made regarding an issue in the field of science are referred to as a scientific claim. Scientific claims are different from any other form of a claim as they are made after a lot of research and are backed by data.
Science is basically a systemically done study of the world around us. People practising in the field of science are called scientists. They collect data, analyze it and based on this analysis they come to conclusions.
Thus a scientific claim is a statement made after coming to the conclusion after analyzing the data.
Even though, a scientific claim is made after thorough research, not every scientific claim is as reliable. The experimentation and analysis can be subject to various errors which can cause a faulty scientific claim.
Therefore, the factor present in a scientific claim would be similar results in multiple tests of the claim.

AsUsing the word "niche” in your answer, explain why this species may have a
higher probability of becoming endangered than a species that eats ten species of plants.
In interspecies competition, two species use the same limited resource. Competition has a negative effect on both of the species (-/- interaction).
A species' niche is basically its ecological role, which is defined by the set of conditions, resources, and interactions it needs (or can make use of).
The competitive exclusion principle says that two species can't coexist if they occupy exactly the same niche (competing for identical resources).
Two species whose niches overlap may evolve by natural selection to have more distinct niches, resulting in resource partitioning.

what is the theory of plate tectonics?
Answer: The theory states that the earth's crust is divided into massive slabs known as tectonic plates.
Explanation:
These plates move on the mantle which is a layer made of magma, which consists of semisolid rocks.The heat from earth's core causes convection currents much like in a beaker full of water.But, here the force developed by the magma is so great that it slowly moves the plates like boats on sea over millions of years.
Although flowers have a common ancestor, they vary quite differently due to the environment and their specific pollinators. This is an example of
Answer:
Divergent evolution.
Explanation:
Divergent evolution can be defined as the process in which more than one group of the same species (from the same ancestors) evolve and possesses (accumulates) various features or traits such as behavior or bodily structures, thus, resulting in the formation of new species of the living organisms.
Although flowers have a common ancestor, they vary quite differently due to the environment and their specific pollinators. This is an example of divergent evolution.
All living things must contain genetic material. Which of the following nonliving things also has this characteristic? A. Fire B. Cell phone C. Virus D. Organic phosphates
Genetic material is the hereditary unit found in the cells of every living organism. Viruses are nonliving things that also have genetic material. Thus, option C is correct.
What are viruses?Viruses are organisms that are living and nonliving as they reproduce when once inside the host cell and have the RNA or the DNA as the genetic material inside their capsids.
The protein shell of the virus includes one of the types of genetic material that infects the host DNA by taking control of the host machine to produce multiple copies.
Therefore, the virus is a non-living with genetic material.

Answer:
They interact by the upper mantle transferring energy by conduction to the core assisting in the softening of the rock layer which leads to radiation.
Explanation:
Convection currents coming from the core and mantel are believed to the main cause of the interaction. As these currents travel up and down the curst and mantle boundary and this creates the plates to move freely forming a conveyor belt. The core of the earth creates this convective current to rise up due to the heat and pressure. The hot molten rocks in the mantle eventually cool and the cycle of rising and sinking takes place.Which part of a lake is most likely to have no photosythesis?
