of a frog and a woman.
Appearance*In most frog species, the female is larger than the male, so frog size relative to a standard can be a good method of gender identification. In some species, the female frog is darker in color than the male, and in others, the male is darker.
Typically, frogs lay eggs. This process usually occurs through external fertilization, where the female releases her eggs from her body into water. Then, the male releases his sperm to fertilize them.In this case, the eggs are fertilized inside the female's body before they are released.How many of the 8 actions mentioned in the May 7, 1933 Fireside Address provided jobs for unemployed people?

When a cross between 2 contrasting parents produces new phenotype, different from
either parents, we can conclude that that there is which of the following?
When a cross between 2 contrasting parents produces a new phenotype, it is known as incomplete dominance. In diploid (2n) organisms, individuals receive one allele or gene variant from each parent.
Heterozygous individuals carry different alleles for the same gene locus.
Incomplete dominance occurs when both alleles are expressed in heterozygous organisms.
The phenotype in cases of incomplete dominance is a mixture of the phenotype observed in both parents.

Temperature-sensitive alleles are an example of conditional alleles; at the permissive temperature, the gene has normal function, whereas at the restrictive temperature, the gene has mutant function. You are studying the E2F pathway and you obtain a temperature-sensitive CDK4 mutant. At the permissive temperature, CDK4 functions normally. At the restrictive temperature, CDK4 is non-functional. Would you expect cells to continue growing or stop dividing when at the restrictive temperature? Explain your answer.
When at the restrictive temperature, we can comfortably expect the cell to stop dividing, whilst continuing to grow
The E2F pathway in a cell is responsible for the transition from the G1 stage of the cell cycle to the S stage. The G1 stage is where a cell grows and expands before the duplication of its DNA.
The S stage stands for synthesis. This is the moment in the cellular cycle in which the DNA of the cell is copied in order to prepare for cellular division.
Therefore, if the transition from G1 to S is blocked by temperature restrictions, we can expect the cell to continue growing, but not divide.

Three plants are grown in the same environmental conditions with equal sunlight, water, and space to grow. One plant grew to have a purple flower while the other two grew white flowers. What is the most likely conclusion that can be made for the change in flower color?(1 point)
Genetic factors caused environmental changes that caused the differences in flower color.
Genetic factors caused the differences in flower color.
Environmental factors caused a genetic mutation that caused the differences in flower color.
Environmental conditions caused the differences in flower color.
Answer:
The second answer choice.
Explanation:
Genetic variation must be the answer as the plants were grown in the same conditions. Therefore, the only source of variability might be genetic variation.
The first choice is not the answer because Genetic factors cannot cause the environment around the plant to change.
The third choice is not the answer because the Environmental factors are the same, and if they were really to cause a mutation, all three plants would mutate.
The fourth is the same reason as the third: if environemnt conditions affected the flower, all three plants would change color since they were all grown in the same environemnt, not just the one we see in the results.
Some significant floricultural species can now produce flowers with attractive and unique bloom hues thanks to recent advancements in genetic alteration techniques. Thus, option B is correct.
What are the genetic factor in developing organism?Flower color is governed by two primary gene families. Genes that code for the protein machinery needed to create pigment molecules are part of one category.
The second group includes genes that result in the production of regulatory proteins. The location, quantity, and kind of machinery that makes up the pigments are determined by regulatory proteins.
Flowers have genes that determine how they look, just like humans. These plants “give birth” to pigments, which result in a rainbow of hues.
The carotenoid substance that gives tomatoes and carrots their color also gives some flowers their yellow, red, or orange hue.
Therefore, Genetic factors caused the differences in flower color.

why do hurricanes weaken when they hit land
Answer: Tropical cyclones usually weaken when they hit land, because they are no longer being "fed" by the energy from the warm ocean waters. However, they often move far inland, dumping many inches of rain and causing lots of wind damage before they die out completely.
