Answer:
I think that humans would be part of the ecosystem because we produce carbon dioxide for plants, and without carbon dioxide, plants couldn't function. (This is just my opinion on the matter, but if this was a test question, I'd say yes.)
Explanation:
Answer:
Hmmm that's a tough question. In my opinion I believe that they are because they some of us choose to have a role in the ecosystem by helping the Earth become more "green". Maybe think about this, how did we end up here on Earth? (This might go against your science class but we ended up here because God created us all.) I don't know if this helped but I hope that it did. I apologize if it didn't.

Why are feathers "easy to repair"?
Answer: The feathers are easy to repair as the cells of birds help in replacement of damaged and old feathers.
Explanation:
The follicles of the feathers have regenerating cells that help in regrowing the feathers when the feathers are damaged and require to be replaced. The regrowth of feathers is a natural process that happens in all birds. The feathers are replaced by one or two molt seasons per year. In these seasons they shed their feathers and new feathers reappear. The newly growing feathers are stiff, and hard similar to nails.
Club foot is one of the most common congenital skeletal abnormalities, with a world-wide incidence of about 1 in 1000 births. Both genetic and nongenetic factors are thought to be responsible for club foot. C.A. Gurnett et al. identified a family in which club foot was inherited as an autosomal dominant trait with reduced penetrance. They discovered a mutation in the PITXI gene that caused club foot in this family. Through DNA testing, they determined that 11 people in the family carried the PITXI mutation, but only 8 of these people had club foot. What is the penetrance of the PITXI mutation in this family
Answer:
0.727
Explanation:
Penetrance can be defined as a measure of the association between a genotype and phenotype. In medical genetics, the penetrance of a mutation leading to the disease state is the proportion of individuals carrying the mutation and showing disease symptoms associated with such mutation. For example, if a mutation leading to the disease state has a 90% of penetrance, it is expected that 9 of each 10 individuals carrying the mutation will develop the disease, while the remaining 10% will not develop the disease. In this case, 8 of each 11 individuals carrying the PITXI mutation show symptoms compatible with the disease, and therefore the penetrance is 8/11 = 0.727 (73%).
What are the three main categories of forests?
The three categories of forests are separated into temperate, tropical, and boreal.
Answer:
There are three type of forest they include boreal, temperate and tropical forest
Explanation:
Temperate forest is mostly found across the Eurasia and East North America which vary throughout the year mainly because of the of the four main season which are on the latitude. Tropical forest is mainly found near the equator like Central America, Southern Asia and also sub Saharan Africa. Boreal forest is also known as Taiga is known to be the largest biomes land found in North America, Siberia, and Scandinavia.

Answer:
Myelinated axons utilize fewer voltage-gated channels than unmyelinated axons of the same length and diameter.
Myelinated axons are more energy efficient than unmyelinated axons.
Explanation:
Neurons are cells that specialize in transmitting messages to each other using a type of electrical signal. These signals carry information from outside your body to the brain, while others are the instructions for the various organs, glands and muscles to carry out functions.
Neurons receive these signals from other neighboring neurons through their dendrites. The signal then travels to the soma of the neuron, which is the main body of the cell, and finally travels down the axon to the synapse (space between the end of a neuron and another cell). The axon is a neuronal extension through which the electrical signal travels, extending from the soma to other neurons.
There may be layers of myelin, which consist of a layer of fat, covering the axons and where they have the function of acting as insulators to help keep the electrical signal inside the cell, which makes it move faster increasing the speed of transmission of the nerve impulse.
1) Myelinated axons transmit nerve impulses via continuous conduction. FALSE. In the axon, nodes of Ranvier are found at regular intervals along the length of the axon in the myelin sheath that surrounds it. These are small spaces that expose the axon membrane to the extracellular fluid and serve to allow the nerve impulse to travel faster, in a jumping manner and with less chance of error.
2) Myelinated axons transmit nerve impulses in the same manner as unmyelinated axons. FALSE. In an unmyelinated axon, the movement of voltage across the membrane is due to ion flux that is limited by the time it takes for sodium ions to diffuse into the axon. Myelinated axons conduct faster because they are shorter than unmyelinated axons. In the latter, transmission is continuous but slower.
3) Myelinated axons utilize fewer voltage-gated channels than unmyelinated axons of the same length and diameter. TRUE. The action potential conduction jumps from node to node, thereby they need fewer voltage-gated channels. Unmyelinated axons need voltage-gated channels in along the entire axon.
4) Myelinated axons are more energy efficient than unmyelinated axons. TRUE. The rate at which sodium input through one node can depolarize the axon at the next node is related to the current and capacitance across the membrane. Myelinated axons have faster action potential conduction because it jumps from node to node, thereby they use less energy because they don't have to travel the entire length.
5) Myelinated axons would be unaffected by diseases that attack the CNS. FALSE. For example, Multiple sclerosis (MS) is a demyelinating disease of the CNS in which the immune system attacks the myelin sheath or the cells.
The correct statements are:
Myelinated axons transmit nerve impulses via continuous conduction.Myelinated axons utilize fewer voltage-gated channels than unmyelinated axons of the same length and diameter.Myelinated axons are more energy efficient than unmyelinated axons.Myelinated axons are nerve fibers that are protected by a covering called myelin. In both the central nervous system (CNS) and peripheral nervous system (PNS), oligodendrocytes and specialized cells known as Schwann cells work together to generate the myelin sheath. This sheath is composed of several layers of lipids, which are fatty substances that wrap around the axon in segments, leaving small spaces known as nodes of Ranvier.
Therefore, the correct options are A, C and D.

a. F2 generation; h.o.m.o.z.y.g.o.u.s.
b. F1 generation; h.o.m.o.z.y.g.o.u.s.
c. P generation; dominant
d. F1 generation; dominant
(Brainly needs to realize if they let us talk about college biology, that we are going to use words that have h.o.m.o. and that they are genuinely correct scientific terms.
The preferred generation of hybrid offspring is called the P generation and can often be used to determine the dominant gene.
What is P generation and dominant?
Dominant directs to the relationship between two versions of a gene. Then, Individuals receive two versions of each gene, which are called alleles, from each parent. When the alleles of a gene are different, So, one allele will be expressed This is a dominant gene.
When The P generation is the start of Mendel's work on inheritance, or receiving genetic qualities by transmission from parent to offspring. So, Basically that it refers to traits or genes that are passed from a parental generation to its offspring
When P is the parent gene, and also then the offspring goes to the F1 and also then F2, the dominant gene is what gene wins over a recessive. So the correct option is 'C'.

The gecko is a reptile that has the amazing ability to climb smooth surfaces - even glass. Recent discoveries indicate that geckos stick to smooth surfaces via van der Waals interactions between septae on their feet and the smooth surface. When not selling car insurance, geckos climb smooth surfaces.
a. How is this method of stickiness advantageous to the gecko over covalent interactions?
b. Given that van der Waals forces are among the weakest molecular interactions, how can the gecko's feet stick so effectively?
Answer:
a) This method of stickiness is advantageous over covalent interactions because it is weak and easily reversible.
b) The feet are equipped with millions of septae which collectively produce a synergistic effect that produces a powerful adhesive effect.
Explanation:
Geckos have their feet studded with tiny hair-like substances called septae, and these substances interact with the surfaces on which the Gecko climbs using weak van der Waals forces to produce stickiness.
a) The van der Waals interactions for the purpose of climbing is of more advantage over the covalent method of interaction because climbing involves a repetitive action of adhesion to the surface and destruction of such adhesion, and this involves the creation and the breaking of the bonds between the two surfaces easily. van der Waals forces being easily broken helps to achieve effective climbing. If the method of interaction is with a comparatively strong bond, the speed of creation and destruction of such bond is reduced, and the effectiveness of climbing is reduced.
b) Although van der Waals forces are weak forces, each foot of the wall Gecko has millions of septae that each create a van der Waals interaction, and the collective interactions produce a powerful adhesion causing the feet to stick effectively.

b. UATGGCGAAUCG: _________________
c. UGGCGAAUCG:__________________
Answer:
a. the second nucleotide is wrong. It is a U but should be an A. No other nucleotides were effected by this, only the one was effected. This is a Point (Substitution) Mutation.
b. the third nucleotide is wrong. It is a T that was inserted. As you can see, the rest of the nucleotides are right, but since the T was added, it will mess up how the rest of the sequence is read. It will be read UAT GGC GAA... instead of UAG GCG AAU... see how it messed it up? This is an Insertion (Addition) Mutation.
c. the second nucleotide was deleted. This is called a Deletion Mutation. It will mess up the rest of the sequence, similar to how the example above did.
