how does genetic factors influence the growth of trees in a forest?
Hi there. An answer is below!
Explanation:
The genotypes in a plant determines the amount of time it takes to grow. For example, if a plant has genotypes that are young, they will grow quicker. A plant that has older genotypes will grow slower. These genetic factors are what make trees grow quicker or slower than each other.
Part D - The effect of gramicidin on oxidative phosphorylation When the protein gramicidin is integrated into a membrane, an H channel forms and the membrane becomes very permeable to protons (H ions). If gramicidin is added to an actively respiring muscle cell, how would it affect the rates of electron transport, proton pumping, and ATP synthesis in oxidative phosphorylation
Answer:
The correct answer would be -
Remains the same: proton pumping rate, electron transport rate, rate of oxygen uptake.
Decreases or goes to zero: rate of ATP synthesis, size of protein gradient
Explanation:
An H+ channel forms and the membrane becomes very permeable to protons if the protein gramicidin is integrated into a membrane. If gramicidin is added to an actively respiring muscle cell, it will affect the in the following manner:
Remains the same:
proton pumping rate, electron transport rate, rate of oxygen uptake.
Decreases:
rate of ATP synthesis, size of protein gradient
None of these will show an increase due to the addition of gramicidin tlo actively respiring muscle cells.

Answer:
In genetic terms, this kind of change in frequency of alleles in a population over time is known as EVOLUTION. On areas of this farm where pesticides are applied, the presence of the RESISTANCE GENE puts wildtype beetles at a competitive DISADVANTAGE. Yet wildtype beetles breed normally in the refuge area. Because the refuge area directly adjoins the treated field, there will continue to be cross- breeding between wild and resistant beetles in the next generation. For this cross-breeding to be an advantage to the farmer, the resistance gene must be RECESSIVE. and the wildtype gene must be DOMINANT.
Explanation:
Let us analyze each sentence separately.
In genetic terms, this kind of change in frequency of alleles in a population over time is known as EVOLUTION.
Adaptive evolution refers to changes in the organism that lead to the evolution of the species and are adaptive to determine conditions of the environment. Natural selection produces adaptive evolution.
The term resistance refers to an inheritable change in the population sensitivity, reflected through the consecutive failure of the chemical effects, correctly used to reach an effect on the insect population.
In the exposed example, insecticides might produce a genetic modification in the insects, leading them to survive under the effects of the chemical. Insects evolve with the capability of tolerating the poison dose that is usually used to destroy a normal population of plagues.
On areas of this farm where pesticides are applied, the presence of the RESISTANCE GENE puts wild-type beetles at a competitive DISADVANTAGE.
Chemicals act as a selective pressure on areas where pesticides are applied. Some of the insects mutate and develop a resistance gene, becoming capable of surviving the pesticide. Natural selection benefits these mutations. So insects carrying the mutated gene are resistant, while the insects with the wild-type genotype are not. So in the parcel treated with pesticide, wild-type individuals can not survive. They are at a disadvantage concerning the mutated type.
For this cross-breeding to be an advantage to the farmer, the resistance gene must be RECESSIVE. and the wildtype gene must be DOMINANT.
The farmer needs to keep the number of potato beetles low, to protect the crop from the attack of the insects. To keep under control the number of insects, they have to be vulnerable to the chemical. And to be vulnerable to the chemical, insects should carry the wild-type genotype. So to increase the number of susceptible individuals carrying the wild-type gene, it must be dominant over the mutated form, which should be recessive.

If a drug was developed that interfered with the proper functioning of the microtubules found within the axons of neurons, how would you expect this to impact axonal transport processes
Answer and explanation:
If a drug that interfered with the functioning of microtubules found in axons were to be developed, I would expect that axonal transport would be inhibited or at least severely impaired.
Microtubules are proteins made of tubulin that are of key importance in the transport of different proteins, organelles, and synaptic vesicles (among others) to and from the neuron's soma through its axon. Microtubules are part of the cytoskeleton, they rearrange themselves in order to run along the length of the axon so motor proteins like kinesin and dynein can carry diverse structures all through the neuron.
If microtubules were to cease functioning, axonal transport would stop and many processes of great importance for the nervous system, such as neurotransmission, would be hugely affected. This would most likely produce neurological disease.

there is one correct answer
If a force of 6 newtons to the right and a force of 6 newtons to the left are acting upon a ball, the ball will continue with the same velocity.
What is a balanced force?A balanced force occurs when the opposing forces acting on an object is equal.
According to Newton first law of motion, a body will remain at rest until it is acted upon by an external force.
However, a force of 6 newtons to the right and a force of 6 newtons to the left are acting upon a ball, this means that a balanced force is acting on the object, hence, will move at the same velocity.

Suppose a researcher successfully produced a membrane composed of saturated triglycerides rather than from phospholipids. What characteristics would you expect the saturated triglyceride membrane to have
Answer: The options are not given, here are the options from another websites.
a.hydrophilic molecules would easily pass through the membrane.
B. hydrophobic molecules would be attracted to the membrane.
c. the membrane would be fluid at room temperature
d. the saturated triglycerides would not form a bilayer.
The correct options are b and d.
hydrophobic molecules would be attracted to the membrane.
the saturated triglycerides would not form a bilayer.
Explanation:
Triglycerides are substances that are comprises of a higher degree of saturated fatty acid chains in which carbons are connected or linked up by single bonds. Triglycerides are non polar hydrophobic molecules and are therefore attracted by hydrophobic interactions ( that is between water and hydrophobes). Triglycerides helpin maintenance of cell membranes by forming a lipid bilayer.

To obtain energy from starch and glycogen, the body must begin by Group of answer choices converting both starch and glycogen to fatty acids. removing one glucose at a time with a condensation reaction. hydrolyzing both starch and glycogen to glucose. hydrolyzing the starch to glucose and the glycogen to amino acids.
Answer:
Hydrolyzing both starch and glycogen to glucose
Explanation:
Starch and glycogen are both forms of carbohydrates called "polysaccharide" found in the foods we consume. Polysaccharide are polymers that constitutes several monomeric units called monosaccharides. Monosaccharides are the forms in which the body can absorb energy.
Hence, starch and glycogen as polysaccharides must first be hydrolysed (broken down) into a monosaccharide called GLUCOSE in order to obtain energy for the body.

The chemical reaction equation of photosynthesis is shown here:
6CO2 + 6H2O C6H1206
What information is not given in this equation,
It does not show if the reaction is reversible
It does not show the reactants needed for the reaction
It does not show that photosynthesis consists of many separate steps.
It does not show the number of molecules required to produce glucose.
Answer:
It does not show that photosynthesis consists of many separate steps.
Explanation:
Photosynthesis is the metabolic process whereby green plants manufacture their food from inorganic sources in the presence of sunlight as energy source. The chemical equation of the photosynthetic process is given as follows:
6CO2 + 6H2O → C6H1206 + 6O2
The above equation only shows a summary of the photosynthetic process, however, it fails to show that photosynthesis still requires a lot of separate steps to occur. For example, the water molecule undergoes photolysis while the CO2 molecule enters the Calvin cycle. Hence, this equation does not show that photosynthesis consists of many separate steps.

A segment of a DNA molecule has the base sequence ATGAAC. Write a shorthand structure for this segment and for its comp
Answer: The sequence will be 5' ATGAAC 3' and 3' TACTTG 5'.
Explanation:
DNA is a molecule that contains genetic information that codes for protein synthesis in all organisms. This molecule consists of two strands that coil together to form a double helix structure. Each of these chains is formed by nucleotides, which are the monomers of nucleic acids and are formed by the union of a five-carbon sugar (pentose) called deoxyribose, phosphate groups and a nitrogenous base. The nitrogenous bases can be:
Adenine (A) Cytosine (C) Guanine (G) Thymine (T)The two chains are held together by bonds called hydrogen bonds between the bases. Consider that A is only linked to T by two hydrogen bridges, and that C is only linked to G by three hydrogen bridges. This means, both chains are complementary to each other.
The 5' and 3' stand for "five prime" and "three prime", which indicate the carbon numbers on the sugar of DNA. For the classification of the pentoses (which are made of 5 carbones attached to each other), we consider that carbon with the phosphate group is the 5' carbon; and the carbon of with the hydroxyl group, is the 3' carbon. This asymmetry gives a DNA strand a "direction" and causes it to be considered antiparallel, meaning that the nucleotide at the 5' end is first and the nucleotide at the 3' end is last.
Then in this example, the sequence will be 5' ATGAAC 3' and 3' TACTTG 5'.
