Petunia flower color is governed by two alleles, but neither allele is truly dominant over the other. Petunias with the genotype R1 R1 are red-flowered, those that are heterozygous (R1 R2 ) are pink, and those with the R2 R2 genotype are white. This is an example of incomplete dominance. (Note that superscripts are used rather than upper- and lowercase letters to describe the alleles).
a. If a white-flowered plant is crossed with a red-flowered plant, what is the genotypic ratio of the F1?b. What is the phenotypic ratio of the F1?c. If two of the F1 offspring were crossed, what phenotypes would appear in the F2?d. What would be the genotypic ratio in the F2 generation?

The missing part of the question is -

" Is this Primary or Secondary Succession?"

Answer:

The correct answer is - secondary succession.

Explanation:

Recolonization of the plant and animals to habitat after a major disturbance such as flood, lava eruption, wildfire, or human disturbance is characterized as secondary succession.

In this particular case, there is secondary succession occurs, there is man-made disturbance tajes place as logging company clear the spruce trees from a habitat, and after clearing the land the spruce seedlings began to sprout, birds, rabbits recolonize to the area.

Answer:

Measurement (Count) of Cell Numbers:

1. Breed Method:

A known volume of microbial cell suspension (0.01 ml) is spread uniformly over a glass slide covering a specific area (1 sq. cm). The smear is then fixed by heating, stained, examined under oil immersion lens, and the cells are counted.

Customarily, cells in a few microscopic fields are counted because it is not possible to scan the entire area of smear. The counting of total number of cells is determined by calculating the total number of microscopic fields per one square cm. area of the smear.

Answer:

cell mass: The total mass of all the cellular elements in the body which constitute all the metabolically active tissue of the body

Cell number: The sequence of numbers or characters, that when dialed, connects to a particular cellular telephone

Explanation:

Answer:

The correct answer is - the flow of genetic information.

Explanation:

The process includes the flow of genetic information or instructions encoded in DNA used to make or turn to a final product that can be DNA or protein, known as the central dogma.

Mostly central dogma term use for the protein synthesis from the DNA that takes place in the two steps, transcription is the first converts DNA into RNA and the second translation that converts product of the first step that is RNA  into Protein. DNA → RNA → protein.

Thus, the correct answer is - the flow of genetic information.

The central dogma describes the flow of genetic information. The correct option is C.

A key idea in molecular biology known as the core dogma outlines how genetic information moves through cells. It says that RNA is translated into proteins from transcribed DNA.

This idea emphasises how genes are expressed and proteins are made in living things by sequentially transferring genetic information from DNA through RNA to proteins.

The fundamental dogma excludes DNA replication, the reverse transcription of RNA into DNA, and the process of post-translational enzyme modification.

Thus, the correct option is C.

Answer:

to adapt to dryland conditions

Explanation:

The main groups of land plants are vascular plants and they have developed diverse adaptations to survive on land, especially in climatic zones where drought and high temperatures are common. Some of the most important plant adaptations to land ecosystems include, among others, the development of a cuticle to prevent water loss, stomata capable of regulating water evaporation, desiccation-resistant spores coated in sporopollenium polymer, etc. Moreover, in seed plants, which are considered to be the most evolved vascular plants, the endosperm tissue produced inside the seeds is nourished by the parent sporophyte during the first stages of plant development.

Desiccation resistant spores, protective and complex

reproductive organs, and embryos nourished by parental

tissues enable land plants to adapt to dry conditions.

This is the process in which a substance dries up as a result of

loss of moisture.

Answer:

B. Energy is transferred from the cooler air to the warmer ground.

Explanation:

When cooler air particles come into contact with the warmer ground, energy is transferred from the cooler

air to the warmer ground.

Answer: The temperature of air would decrease.

Explanation:

The energy gets transferred from hot object to cold object until the two objects are in thermal equilibrium. When air transfers energy to a cooler object, it means the air it self is cooling down till the air and the object are in thermal equilibrium. Thus, the temperature of air would decrease.

Fats that increases the bad cholesterol in the body are considered worst. Thus, Trans unsaturated fat is the correct answer.

Unsaturated fatty acids have the presence of double bonds. This double bond is either 'cis' or 'trans' in origin.

When the unsaturated compounds are linked through trans bond, they form trans fat.

Trans fat are produced through chemical reaction. This reaction is termed as partial hydrogenation.

Trans fats have shown potential damage to the human body in research studies. Trans fat raises the bad cholesterol level (more lipid, less protein) in the body.

This can lead to several heart disease, liver damage or even atherosclerosis. Such diseases can be life threatening.

Trans fat are found mainly in fried and processed food. The junk food also contains high levels of trans fat.

Therefore, consumption of trans fat should be avoided for health safety.

The option c. A change in the scientific evidence regarding the theory resulted in the change in current scientific theory.

It is a theory that should be explained for the observations for the natural world that should be constructed by using the scientific method.

Also when there is any change in the scientific evidence with respect to the theory so it should have resulted in the change in the current scientific theory.

Subduction happens where tectonic plates crash into each other instead of spreading apart. At subduction zones, the edge of the denser plate subducts, or slides, beneath the less-dense one. The denser lithospheric material then melts back into the Earth's mantle. Seafloor spreading creates new crust.

Answer:

One Joule.

Explanation:

One newton exerted over a distance of one meter equal to one joule.

Joules is the S.I unit used for the measurement of scientific quantities such as work and energy and it was named after the prominent English physicist, James Prescott Joule.

Given the following data;

Force = 1N

Distance = 1N

Therefore, we know these parameters or quantities are directly related to work.

Mathematically, work done is given by the formula;

Work done = force * distance

Where,

Substituting into the equation, we have;

[tex] W = 1 * 1[/tex]

Work done = 1 Joule.
