Explanation:
Some flowers show incomplete dominance. If RR = white and R'R' = red, which phenotypic ratio would
be expected in the o spring of two pink flowers?
Answer:
1 red: 2 pink: 1 white
0 red: 4 pink: 0 white would be the phenotypic ratio expected in the o spring of two pink flowers. So, the correct option is (D).
What is Phenotypic ratio?Phenotypic ratio defined as the relative number of offspring expressing a particular trait or combination of traits, which can be determined by performing a test cross and the frequency of the trait or trait combinations being expressed depending on the genotype of the offspring can be identified.
Phenotypic ratio is expressed as the ratio of different phenotypes present in the progeny of a cross where the ratios are numerical comparisons. For example, if one has three mangoes and two oranges, the ratio of mangoes to oranges will be 3:2.
For above given information, if we cross RR which is white with R'R' which is red, we will get 4RR' offspring which are pink in color. then the ratio will be 0 red: 4 pink: 0 white.
Thus, 0 red: 4 pink: 0 white would be the phenotypic ratio expected in the o spring of two pink flowers. So, the correct option is (D).

Pioneer species such as lichen and moss inhabit an area after a major disturbance such as a volcanic eruption. Over time, other species are found in the disturbed area and the number of pioneer species decreases. Why does the number of pioneer species decrease? The amount of available sunlight is reduced. The pioneer species can no longer thrive. ⊝ The area has more soil to support complex plants. The competition increases between organisms. ⊝ The area is more susceptible to the wind. Seeds are captured in the pioneer plants and germinate at a higher rate. ⊝ The temperature is not as extreme as it was following the disturbance. Fewer of the pioneer species reproduce. ⊝ CLEAR ALL ❮ PREVIOUS ... 3 4 5 6 7 8 9 10 11 12
Answer:
The competition increases between organisms.
Explanation:
Primary succession occurs after a disturbance or disaster that leaves open spaces with no living organisms. These new open areas are the case, for instance, of a bare rock exposed due to a retreating glacier, a volcanic activity, or an intense fire. No previous species inhabiting this area are left.
These scenarios allow new species to grow. With time, new species arrive and manage to establish again. The order of the establishment depends on the strategies of each of the species to survive.
First, pioneer species arrive. These are the first inhabitants, mostly lichens or plants with the capability of surviving in such an environment. Only a few pioneers can establish in the open space. Pioneers modify the habitat. They make it more suitable for the posterior establishment of later species, converting rock into fertile soil. As conditions get better, new species arrive like grasses. Grasses and pioneers keep modifying the ground and making it better with time. Competition becomes more frequent between species. The first species are eventually eliminated by competition, while new species keep appearing and competing for resources. Habitat modification keeps on going while new species establish. They produce shadows, alter the temperature, and humidity, fertilizing the soil, competing for resources. Competition becomes more frequent between species. This sequence continues until there is not more facilitation, and the commuting reaches a climax, becoming stable and lasting for hundreds of years until another disturbance occurs.
As a result of the experiment scientists did with Mexican tetras, it seems likely that their first hypothesis about blindness in the tetras is right. Explain how the result of the experiment supports their first hypothesis.
The scientists' first hypothesis is that blindness gives the fish some sort of evolutionary advantage, but not directly.
The experiment was: The scientists transplanted a lens from the eye of a surface tetra embryo into the eye of a cave tetra embryo. The result was striking—the surface tetra lens into the cave tetra caused all of the surrounding tissues to develop into a healthy eye.
A result that supports the hypothesis 'blindness gives the fish some evolutionary advantage, but not directly' may be a higher fitness in close relatives of fish.
What is a hypothesis?An scientific hypothesis is a given explanation to a scientific observation from the real world.
A hypothesis must be verifiable, which means that it can be confirmed or rejected by using the scientific method.
In conclusion, a result that supports the hypothesis 'blindness gives the fish some evolutionary advantage, but not directly' may be a higher fitness in close relatives of fish.

What process occurs when a river velocity increase and why
Answer:
Flood Erosion and Deposition: As flood waters rise, the slope of the stream as it flows to its base level (e.g., the ocean or a lake) increases. Also, as stream depth increases, the hydraulic radius increases thereby making the stream more free flowing. Both of these factors lead to an increase in stream velocity.

A,proteins, organelles, cells, organisms
B,proteins, cells, organelles, organisms
C,cells, organelles, proteins, organisms
D,organelles, cells, proteins, organisms
d
Cells, organelles, proteins, organisms describes the organization within multicellular organisms from least complex to most complex. The correct option is C.
What are multicellular organisms?Multicellular organisms include a mixture of more than one cell, with differentiating groups of cells performing specialized functions.
Early stages of development, cells in humans distinguish towards becoming nerve cells, skin cells, muscle cells, blood cells, as well as other types of cells.
All animals, land plants, and most fungi are multicellular, as are numerous algae, with the exception of slime molds and social amoebae such as the genus Dictyostelium, which are partially unicellular and partially multicellular.
Cells, organelles, proteins, and organisms describe the organization of multicellular organisms in descending order of complexity.
Thus, the correct option is C.

The best explanation for the presence of vestigial pelvis and femurs in some snake and whale species is
Answer:
a common ancestor that used these structures to perform one or more specific functions
Explanation:
A vestigial structure is an organ that has no obvious function in an organism, but it has been used by a past ancestor to perform one or more specific functions. Thus, vestigial structures have been retained in the course of evolution, but they lost their ancestral functions. Vestigial structures/organs can be detrimental for the organism because it is required energy to maintain them and they may suffer diseases (e.g., cancer). Some well-known examples of vestigial organs/structures include, among others, the wings of ostriches and cormorants, the human appendix, etc.

Answer:

Photoperiodism is one example of how a plant responds to changing seasonal conditions. Why is it important for plants to be able to respond to seasonal changes?
Answer:
It is important because plants respond to light depend, logically enough, on the plant's ability to sense light. Phototropism is a directional response that allows plants to grow towards, or in some cases away from, a source of light. Photoperiodism is the regulation of physiology or development in response to day length.
