PLEASE HELP! WILL GIVE BRAINLIEST! Are traits controlled by dominant alleles more common than traits controlled by recessive alleles? Please explain
Answer:
depends on F1 and F2
Explanation
Dominant traits
Dominant trait is a characteristic that clearly expresses, overwhelms other traits of the same type in a heterozygous genetic combination; is shown mainly in the F1 generation.
Diving traits
Recessive trait is a trait that cannot be expressed because it is overwhelmed by other traits of the same type (with a pair of symmetrical alleles) in a heterozygous genetic combination; recessive has not been shown in F1, but only occurs in F2 generation.

What provides structure for plants
1. Carbonhyrdrates
2. Lipids
3. Nucleic acids
4. Proteins
Answer:
The correct answer is : 1. carbohydrate.
Explanation:
Cellulose is a major substance present in cell walls of the plants which provides support to the structure of plants. As it is most abundant bio polymer in nature are made up of monomers of glucose molecule joined together by bonds in between specific carbon atoms.
The rigidity of the plant is come from this carbohydrate, cellulose. Lipids, proteins are also component of the plant cell and plays various role in the cell for instance lipid acts as barrier and present in plasma membrane of the plant cell and provide insulation too.
Thus, the correct answer is : 1. carbohydrate.

Why don't the spontaneous deleterious mutations that occur in an individual
e.coli cause downward drops in fitness in this population? see section 23.6 ( page 475) ?
Answer:
Please see below
Explanation:
The reason behind this is the phenomenon of natural selection. The deleterious mutations do not provide a survival advantage so they are selected against, which results in these type of mutations to not be passed on - rather, they eventually get eliminated from the population.

How does the distance from this eye chart affect the number of letters visible on a line? What factor of the experiment is the eye chart? Control Group, Control Variable, Independent variable, or Dependent variable
Answer:
This question is asking to identify the variable in the experimental statement.
The eye chart is the CONTROL VARIABLE
Explanation:
An experiment consists of several variables to look out for in order to achieve any significant result. These variables are independent variables, dependent variables and control variables. Although independent and dependent variables are the major experimental variables, but control variables are also important.
A control variable is the variable that remains constant or unchanged throughout the experiment. Any change to the control variable will affect the dependent and independent variables. In this question, the eye chart is the CONTROL VARIABLE because it remains constant or unchanged. The same eye chart is used for the experiment.
N.B: The distance to the eye chart is the independent variable while the number of letters visible on the line is the dependent variable. Hence, changing the eye chart (control variable) will affect the distance and the number of letters visible.
The central nervous system includes all of the following except: brain spinal cord nerves that reach the tissues in limbs cerebellum
Answer:
My answer is the CNS consist of the brain and the spinal cord nerves but not cerebellum.
The nerves that reach the tissues in limbs is not the part of the central nervous system.
• The central nervous system or the CNS mainly is formed of the spinal cord and the brain. However, it generally is considered to exhibit seven fundamental parts, that is, the spinal cord, the pons, the medulla, the midbrain, the cerebellum, the cerebral hemispheres, and the diencephalon.
• The parts of the nervous system apart from the brain and the spinal cord is known as the peripheral nervous system.
• It comprises the spinal nerves, the cranial nerves and their roots and branches, the neuromuscular junctions, and the peripheral nerves.
• The bundles of axons or the nerve fibers transmit information to and from the central nervous system in the peripheral nervous system.
Thus, the nerves that reach the tissues in the limbs is the part of peripheral nervous system not central nervous system.

Explanation:
Mitosis, followed by cytokinesis, results in the formation of two genetically identical daughter cells. This is because:______
a. after replication, the material is compared and corrected to be identical. the chromosomes pair up (synapse) in prophase as a counting mechanism.
b. all the genetic material is duplicated then segregated equally to the daughter cells.
c. daughter cells are initially haploid, but they duplicate their chromosomes to become diploid again.
d. the number of chromosomes needs to be reduced before cytokinesis.
Answer:
b.
Explanation:
The correct answer would be that all the genetic material is duplicated then segregated equally to the daughter cells.
Mitosis has to do with the division of vegetative or non-reproductive cells in the body of organisms. At the interphase stage of each cell cycle prior to mitosis, the genetic materials of the cell are doubled or duplicated.
These genetic materials are then distributed equally to the two daughter cells that are produced at the end of the mitotic process. It thus means that the resulting daughter cells are genetically identical in all ramifications.
The correct option is, therefore b.
Mitosis, followed by cytokinesis, results in the formation of two genetically identical daughter cells because: B. all the genetic material is duplicated then segregated equally to the daughter cells.
Mitosis refers to a type of cell division (duplication) through which a single (1) parent cell produces two (2) genetically identical daughter cells.
In a mitotic division, the two (2) genetically identical daughter cells produced by one (1) parent cell generally have an equal number of chromosomes as their parent cell, this process is referred to as duplication division.
In this context, if a cell divides by mitosis followed by cytokinesis, this would result in the formation of two genetically identical daughter cells because all the genetic material is duplicated and then segregated equally to the daughter cells.

Why do field researchers and laboratory researchers use tools that are similar and tools that are different
Answer:
Please see below
Explanation:
These two types of research, that is, in the laboratory and in the field, are very different from each other for a number of reasons. For one, the study is conducted on a much larger scale when it is done in the field as compared to when it is confined in the lab.
Tools such as PCR (polymerase chain reaction) would be common between the two since there is no substitute for it. However, other tools used that have various other purposes will be different between the lab and the field. For instance, a quadrant will be used to count plants in a field, but none is needed in the lab due to a smaller number of plants being studied.

Si una persona sana que no tiene mutaciones en el cromosoma 4 decide tener hijos con una persona heterocigota (A/a) que padece de la enfermedad de huntington, ¿cuál es la probabilidad de que esta pareja tenga hijos que padescan la enfermedad?
Answer and Explanation:
Cruza: persona sana sin mutaciones con persona portadora
El parental sano aporta alelos normales del gen a la descendencia
El parental portador aporta un alelo normal y un alelo alterado. Tiene el 50% de probabilidad de transmitir la enfermedad a la progenie.
Parental) AA x Aa
Gametas) A A A a
Cuadro de Punnet) A A
A AA AA
a Aa Aa
F1) 2/4 = 1/2 = 50% de la progenie seran individuos sanos AA
2/4 = 1/2 = 50% de la progenie seran individuos portadores Aa
Como uno de los progenitores es portador, cada individuo tiene un 50% de posibilidades heredar el gen alterado.

You are a forester charged with increasing productivity in a South American forest newly planted with pines from Oregon. You believe that the southern forest lacks the fungal diversity needed by the North American pines and that this lack of fungi is affecting the pines' productivity, but you have no evidence to support your ideas. Which of the following would be the best approach to assess the diversity of fungi likely contributing to tree productivity in the Oregon forest?
a. Do direct sequencing on representative soil samples from across the forest.
b. Expose the trees to radiolabeled CO2and then collect the soil samples with the greatest radioactivity and do direct sequencing.
c. Collect all the fruiting structures (mushrooms, morels, etc.) found above ground.
d. Count all the plant species and multiply by six, as David Hawksworth did when determining the ratio of fungal to plant species in England.
Answer:
The correct answer is : option A.
Explanation:
In this case an individual is experiencing low pines productivity. According to him that lack of fungal diversity affects the productivity of pines in southern forests.
To test this hypothesis or idea the best approach among the given option is to run a direct sequencing on soil samples from all across the forest. By sequencing representative soil samples for the will help in assessing the fungal diversity in particular soil sample and on that basis one can find the relation with productivity of pines.

Compare and contrast the functions of each of the following types of flasks: filter, Erlenmeyer, volumetric. (Site 1)
Answer:
Explanation:
1. A filter flask is made up of heavy, transparent glass and suction pump at one side. This kind of flask is used for filtering or distillation of substances and is not the best option for measuring as it is not accurate.
2. An Erlenmeyer flask is a conical flask that is best suitable for titration and for storing chemicals.
3. Volumetric flasks are the best kinds for preparing accurate volumes. They are used for making accurate measurements of solutions.
Answer:
See Below
Explanation:
The filter flask is an Erlenmeyer flask with a side-arm adapter. This arm allows a scientist to remove unwanted impurities from solids, liquids, or gases in a chemistry experiment. Ultimately, it allows the fluid, or filtrate, to pass through, but stops the solid particles in the process. The Erlenmeyer flask is designed with a flat bottom so it can be used to either boil a liquid or allow a liquid to form condensation. This flask allows a laboratory technician to stir or heat a solution without losing any liquid by placing a stopper in the neck. Lastly, volumetric flasks are used for creating solutions. With their long, narrow neck and flat-bottom, these flasks have a number of advantages and disadvantages. Their specific set of measurements provides a scientist great accuracy. A scientist can use this flask to create solutions, when a solute is mixed with a solvent. It can also be used for dilutions, when a liquid is made thinner by adding water or another solvent. However, because the neck of the flask is so narrow, it can be difficult to pour the measured liquid out of the flask if the scientist over-poured the measurement.
