The answer is the letter B. a hypothesis

*A hypothesis is a possible explanation that corresponds to set of observations

During his experiments, Mendel used the pea plant as an object of study. Some of the reasons were that these plants have genetic variability (different color, shape or size), crossing between varieties is easy, and self-pollination can be prevented by removing the anthers of the flowers.

Since Mendel's experiments did involve dominant and recessive alleles for a trait, and flowers can be easily protected from foreign or self-pollinated pollen, the answer is D (a plant that has only 2 alleles for a trait), since the traits that Mendel evaluated as color or shape had two alleles for each trait (color: yellow/green, shape: smooth/rough).

Answer: The properties of soil is giving the nutrients needed for the plant to survive, and help it stay in healthy shape, now the structure must be very important in order for the plant to receive its nutrients in the specific process needed.

Hope that helps.

The properties of soil is giving the nutrients needed for the plant to survive, and help it stay in healthy shape, now the structure must be very important in order for the plant to receive its nutrients.

Color, texture, structure, porosity, density, consistence, aggregate stability, and temperature are among the physical characteristics of soil. These characteristics have an impact on biological activity, nutrient cycling, infiltration, and erosion.

Soil structure is one of the most important soil's physical factors controlling or modulating the flow and retention of water, solutes, gases, and biota in agricultural and natural ecosystems.

The movement of air, water, solutes, and heat through the soil is governed by the physical characteristics of the soil. Depth, temperature, texture, structure, bulk density, and water-holding capacity are the primary physical characteristics of soil.

Correlation is a statistical method used to proof the relationship between two quantitave or categorical variables. It does not establish causality between the variables. All you can conclude from the statement is that "taking vitamin C" and "the decrease of cold symtoms" are somewhat related.

To determine the nature of the relationship you need to do further investigation.

The correct answer is a.

The correct options include C, D, E and F

The diagram doesn't show any external interferences, such as mutations (the populations all have the same types of individuals) or recombination (there's no new types of indivudals or combination of those types). Therefore, D and A are incorrect.

There is a separation of the first population, so only natural selection wouldn't explain the outcome, therefore C is incorrect as well.

The genetic drift occurs when there are random fluctuations in a population. In smaller populations, such as this one, this random fluctuations can lead to an event called Founder event. In this case, an isolated founder population creates descendants that are selected and different due to random drift. Therefore, the correct answer is: B. how genetic drift can affect allele frequency in a population.

Answer:

7) A. $96

8) A. $216

9) C. $86

10) E. $88

Explanation:

7) Clothes = hat (3%) + sneakers (21%)

Hat: $400 * 3%(0.03) = $12

Sneakers: $400 x 21%(0.21) = $84

$12 + $84 = $96!

8) Find snowboard percentage by:

100% - (The all revealed percent)

= 100% - (21%+14%+8%+3%) = 51%

= $400 * 51%(0.51) = $216

9) Video games = 14%

= $400 * 41%(0.41) = $86

10)

Dvds: $400 * 8% = $32

Video games = $86

= $32 + $86

What we see in the image is a genealogy, where a disease or trait is highlighted. Each square and circle represents an individual, and its color represents whether they have the disease (completely black), are carriers (half and half), or are healthy (white).

In this case, both squares and circles can be carriers, so this is not a disease carried in the sex chromosomes, and this also means two copies are needed for the disease to express, so the individual with the disease (black) are homozygous recessive. This means that individual 5 from generation II is NOT homozygous recessive.

Usually, squares represent males and circles represent females, so that means that II-5 would be a female heterozygous.

A)In this case, we are talking of nicotinic and muscarinic receptors, in the first case the nicotinic is called like that because nicotine can activate them, meanwhile the second is not, so in the table type one would be nicotinic meanwhile type two would be muscarinic. So nicotinic receptors are ligand-activated receptors, they possess hetero-oligomers of five subunits each with four transmembrane domains, meanwhile the muscarinic are coupled to a G protein, consist of individual proteins with seven transmembrane domains.

Nicotinic receptors allow the entrance of NA+ ions or the exit of K+, In some other cases allow the pass of Ca+, depolarizing the cell and generating a postsynaptic potential. Meanwhile, the muscarinic receptors mediate the subsequent hyperpolarization (recovery of the neuron after depolarization) and a type of depolarization (slow polarization).

B)Actilcholinesterase hydrolyzes the acetylcholine and that way ends the action of the neurotransmitter released in the synaptic cleft, if this neurotransmitter is not eliminated the ionic channels mediated by the receptors would not open again, as long as the acetylcholine is still detected once depolarization occurred the channel will not open, so muscular contraction cannot happen normally if acetylcholinesterase is inhibited.

Individual 4 in generation II has a genotype of Aa.

This is an example of heterozygous pair. The presence of two different alleles at a particular gene locus. A heterozygous genotype may include one normal allele and one mutated allele or two different mutated alleles.

This is an example of heterozygous pair.

The term “heterozygous” also refers to a pair of alleles. Unlike homozygous, being heterozygous means you have two different alleles. You inherited a different version from each parent. In a heterozygous genotype, the dominant allele overrules the recessive one. Therefore, the dominant trait will be expressed.

Moreover, the presence of two different alleles at a particular gene locus. A heterozygous genotype may include one normal allele and one mutated allele or two different mutated alleles.

Therefore, an organism that has the same two copies of a gene is considered homozygous for that trait, while an organism that has different copies of a gene for a particular trait is considered heterozygous for that trait.

Because sunlight is needed to break down h2o and co2 molecules in to c6h12o6

The organism in the diagram that can be considered a producer is the Grain,

Degraded habitats often have very low diversity often with large populations of organisms that are present because the carrying capacity for native plants, animals, and other species is diminished.

When a habitat is destroyed, the carrying capacity of native plants, animals, and other species is reduced, which causes populations to decrease and occasionally reach the point of extinction. Loss of habitat is arguably the biggest hazard to organisms and biodiversity.

The main cause of biodiversity loss is habitat loss brought on by resource extraction, agricultural conversion, and urbanization. As a result of habitat fragmentation, there are now isolated little areas of land that cannot support species populations in the long term.

While habitat restoration can boost local biodiversity and species populations, habitat loss can split ecosystems and result in the extinction of species.

A hypotonic solution has a lower concentration of solutes than the other solution, in this case, the cytoplasm of the plant cell.

This means that the water will move towards the interior of the cell by osmosis. The plant cell can put the water in vacuoles, the cell will still gain that water, and they become turgid (swell), but they do not burst because of the cell wall.

This means A. It will swell, would be the right answer.

Hypotonic solution refers to the condition where the cell has less concentration compared to the outer environment, that is the cell has low concentration of solutes. Therefore, it will swell in hypotonic solution.

Concentration of a cell is controlled by the plasma membrane of the cell. There are three conditions of the concentration of cell such as - hypertonic, where the concentration of the cell is higher than the surrounding of the cell.

Hypotonic, when the concentration of the cell is lower than the surrounding of the cell.

Lastly, isotonic, where the concentration of the cell is as same as the surrounding.

The concentration of the cell depends on the flow of solute molecules from cell to outside and inside. Therefore, according to the condition in the question the cell will swell in a hypotonic solution.
