The negative charge established along a nerve cell membrane is due to (select all that apply) A. movement of Cl- into the cell B. movement of proteins out of the cell C. movement of Na into the cell D. higher permeability of K relative to Na E. intracellular protein anions
The negative charge established along a nerve cell membrane is due to the D.higher permeability of K relative to Na.
Whilst the membrane will become permeable to k+, the k+ ions will freely waft until that membrane potential is reached. In this case, the ok+ ions will float OUT of the mobile, contributing to the mobile's hyperpolarization (from -70mV towards -96mV) within the path of the k+ equilibrium potential.
The bad charge inside the cellular is created via the cellular membrane being greater permeable to potassium ion movement than sodium ion movement. In neurons, potassium ions are maintained at excessive concentrations in the mobile whilst sodium ions are maintained at high concentrations out of doors of the cellular.

Mutation resulting from changes in a single gene is called ______________. gene mutations chromosomal mutations chromosomal aberrations translocation
Mutation resulting from changes in a single gene is called Gene mutation.
A gene variation is an alteration to a gene's DNA sequence that takes place throughout time. Gene variation is regarded to be a more accurate word for this sort of genetic change than gene mutation since changes in DNA do not necessarily result in illness.Gene variations can be acquired from one's parents or develop naturally over time.Inheritable variations are present in almost all of a person's cells throughout their lifetime and are transferred from parent to kid.Non-inherited variations appear at some point in a person's life and are found in just a subset of the body's cells, not all of them. Non-inherited variations are sometimes referred to as somatic variants since they generally arise in somatic cells.So we can conclude that a gene variation is a change in a gene's DNA sequence that occurs over time; it is thought to be a more appropriate term for this type of genetic change than gene mutation because DNA variations do not always cause disease, it also resulting from changes in a single gene.

Phenylketonuria (PKU) is a disease in humans where the function of the enzyme phenylalanine hydroxylase is impaired by mutation of the human PAH gene. Untreated, individuals with PKU can have intellectual disability, behavioral problems, and seizures. However, people who eat a diet low in phenylalanine can lead a normal life. What terms describe PKU as a trait
Pleiotropy refers to the phenomenon of a single gene affecting multiple traits. Phenylketonuria is an example of Pleiotropy.
What is Pleiotropy?The production of diverse effects, especially the production by a single gene of several distinct and seemingly unrelated phenotypic effects known as pleiotropy.
Phenylketonuria, generally known as PKU, is a rare hereditary condition that results in an accumulation of the amino acid phenylalanine in the body. The phenylalanine hydroxylase (PAH) gene is altered in PKU. The enzyme required to degrade phenylalanine is produced in part because of this gene. PKU can be seen to behave as a 'complex' trait.

Many farmers and gardeners compost their plant and animal waste. The living material naturally decays in compost bins, forming a dirt-like substance that’s rich in nutrients. The next season, farmers use this substance as a natural fertilizer for their crops.
A biology student has grown tomato plants for several years. Until now, he used an artificial fertilizer formulated for tomato plants. This fertilizer caused his plants to grow faster and taller than they grew in unfertilized soil. The student wants to know whether using natural compost will cause his tomato plants to grow faster and taller than his artificial fertilizer.
The use of artificial fertilizer has helped the tomato plant to grow faster and taller.
Natural fertilizers such as plant and animal wastes are considered eco-friendly as they are not harmful to the environment. They add nutrients to the soil in a natural way and do not degrade the soil. But, their impact is slow and cannot fulfil all the lacking nutrients. On the other hand, artificial fertilisers are harmful to the environment as they degrade the soilStill, the farmers prefer artificial fertilizers over natural fertilizers. This is because they help the plant to grow faster and taller by fulfilling the requirement of all lacking nutrients.Thus, tomato plants are grown faster and taller due to the use of artificial fertilizers.

Explanation:
which model best shows the movement of water during photosynthesis
Answer:
Soil → Plant
What happens in photosynthesis?
The light is energy. So the plant doesn't convert light to energy, light already is energy. The plant uses the light energy to grow, and to store energy in a different form (like how you eat corn, and gain energy to run and stuff, your body converts the corn to fat so you can use the energy later.)
Now, as for the creation of oxygen, we have to go deeper. In the air there is CO2, which is 2 parts oxygen and one part Carbon. Plants "breathe" it in. From the ground the plants get water, H2O, which is 2 parts Hydrogen and 1 part Oxygen, right? The plant uses the light energy to convert the C02 and H2O into Sugar, C6H1206 (6 Carbons, 12 Hydrogens, 6 Oxygens)
So we see that there must be 12 Hydrogens in the end, but H20+C02 only has 2. That means you need 6 H2O molecules, which fuse with 6 C02 molecules (becuase sugar has 6 carbons as well)
What we get is (6)H2+(6)C+[(6)02+(6)O] which we can algebra into H12+C6+O18. Now we subtract the sugar, which the plant stores (C6H12O6) and we are left with 012, or Twelve Oxygens. Oxygen doesn't like being alone, so we would represent it as 6 oxygen pairs (6)O2. That oxygen gets released back into the air. Boom.

Human skin cells are replaced every 20 days, while human brain cells last 30 to 50
years. Why would brain cells need to last for so long? Why might this be a problem if
we managed to extend human life beyond 100 years?
In this question, there is a misinterpretation of the term "cell lifetime."
The body's structural building blocks are called cells. One of the body's methods for improving performance over time is to extend cell longevity.
Blood and skin cells are examples of "deliberately" disposable cells. This is because the best method for a cell's function is cell turnover. Skin cells are harmed when they are exposed to the abrasive outside environment. A wonderful method for combating the entropy of environmental harm is to slough them off and replace them with fresh ones. Red blood cells are transient "by design" since they lack a nucleus.
The brain's neurons are tuned for a fundamentally different purpose: memory. The brain's objective is to improve throughout time by building up knowledge and memories. These abilities and memories are "stored" as subtle structural adjustments to the way the brain's neuronal connections are organized. In order to maintain that structure as long as possible, the brain must. Since cells are the only thing that exist, the structure of neurons takes the form of their peculiar cell forms, which resemble the complicated tree branches that wind through the brain. If a neuron dies, it also leaves behind its structure and memories. Therefore, neurons should never die in the brain according to ideal design. This has resulted in several safeguards for this structure, including the blood brain barrier that guards against poisoning and the hard shell of the skull. '
Long-term brain health would be an issue if humans could live longer than 100 years. We would need to make investments in preventing this catastrophic mental failure as well as create therapies to keep the brain "fresh" because the brain did not adapt to endure that long (for example, dementia).

How do the basic principles of inheritance which Mendel found in plants differ from those which are found in humans
The inheritance in humans is more complex as compared to the inheritance in plants as described by Mendel.
Mendelian inheritance patterns mostly refer to the inheritance of traits controlled by a single gene with two alleles. In plants, most characteristics are governed by a single gene but in humans, most of the traits are polygenic which means that they are governed by more than one gene.
Also, most of the genes in humans have more than two alleles and hence they do not follow simple Mendelian inheritance patterns.
In humans, the males have only one X chromosome (that contains sex-linked traits) and females have two X chromosomes, this also leads to more complex patterns of dosage compensation and inheritance in humans and they do not follow the basic Mendelian laws as the plants do.
