What are the phenotypic ratios of a white-eyed female is crossed with a red-eyed male

Answers

Answer 1

Answer:

We need to cross a white eyed female (XwXw) and red eyed male (XRY).  

The cross can be shown as:

 Xw Xw

XR XRXw (female, red eyed)  XRXw (female, red eyed)  

Y XwY (male, white eyed)  XwY (male, white eyed)  

Thus, in the offspring we will have the following phenotype:

Males: White eyed.  

Females: Red eyed.

why is it important to understand the relationship amoung organisms in an ecosystem

Answers

Relationships Between Organisms:


Species interact every day. That interaction is a vital part of how organisms develop and change over time. When you study species, it is important to watch the way they interact with their surroundings.
All organisms in an ecosystem are connected in one way or another. In fact, populations of different species generally interact in a complex web of relationships. Relationships between species in communities are important factors in natural selection and help shape the evolution of the interacting species.

The theory of evolution states the change in the traits to adapt and survive the altered conditions. Offsprings, artificial selection, natural selection, diversity and adaptation are the correct blanks.

What is natural and artificial selection?

Animals or the species of the organism breed and reproduce to produce offspring or the progenies that continues the lineage of the specific species.

Artificial selection is the process of choosing the animals that have better characteristics over another and is done by humans. It is done in order to select the genetically variable species.

Charles Darwin gave the theory of evolution based on the mechanism of natural selection that states that nature chooses the fit and animals with better traits and qualities that can adapt to the change and continue to reproduce.

During his voyage of the Galapagos island, Darwin discovered the diversity of the bird and tortoise species of the same kind but with different attributes at different places. The species adapted differently with respect to the environmental conditions for survival.

Therefore, the correct order of the blanks is 4. offsprings, 5. artificial selection, 6. natural selection, 7. diversity and 8. adaptation.

There are three stages of the dragonfly life cycle, the egg, the nymph, and the adult dragonfly. Most of the life cycle of a dragonfly is lived out in the nymph stage

Life as an Aquatic Larva

Incomplete metamorphosis consists of the egg, the larva (nymph) and the adult. After the egg hatches, the free-crawling aquatic larva molts once and then starts hunting voraciously. As the larva grows, it will molt numerous times. Most dragonfly larvae mature to adulthood in one to three years. so maybe *(c.)

divergent plate boundaries can form chains of underwater mountains, called mid-ocean ridges. Explain how the formation of these ridges occurs.
Your answer should include at least two complete sentences.
Be sure to check your grammar and spelling.

Answers

!

Mid-ocean ridges occur along divergent plate boundaries, where new ocean floor is created as the Earth's tectonic plates spread apart. As the plates separate, molten rock rises to the seafloor, producing enormous volcanic eruptions of basalt.

A mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. This uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary.

People claim these rock formations in the Sahara Desert look like a mushroom and a chicken. They were not sculpted by humans. What do you think caused them to be shaped this way?

Answers

mainly because of erosion by the wind, which geographers call abrasion. When the wind blows in some hot deserts it will pick up millions of grains of sand. When the wind hits an outcrop of rock the sand it is carrying is blasted against it. Over time it would form to become that funky mushroom shape.
hope this helped! :))

The process is known as erosion and it leads to the creation of a large number of shales and sizes of structures such as a pedestrian or mushroom-shaped rocks that have a wide top and a narrow base.

The rocks were re-sculpted as per the wind direction and intensity. Due to the action of wind the and is carried and is known as the abrasion process. The grains of sand are used as tools to polish the surface of the rocks.

In January, the temperature in the southern part of Florida dropped below freezing several nights in a row. One fruit grower commented that climate was really bad for the orange crop this year. Why was his comment incorrect?


Climate refers to precipitation instead of temperature so the climate did not change.

Cold weather can sometimes occur even in a warm climate such as southern Florida.

It would have to be cold for many nights in a row to indicate that the climate had changed.

The climate in Florida does not ever change so it is only the weather that can be bad for the crop.

Explanation:

tdlr-  internal environmental factor, genes, hormones

The image shows an example of an external environment affecting her fish's growth. Other conditions that could affect animal growth include internal environment.

What is environment?

An organism's or an ecological community's environment is the collection of physical, chemical, and biological variables that affect it and ultimately decide its form and survival.

Everything in our environment affects us. Whether they are living or not is up to you. It consists of natural forces such as chemical and physical ones.

Environments are where living things exist. They are continually interacting with it and modifying their behavior to fit the circumstances.

Clean air and water, rich land for growing food, as well as energy and material inputs for production, are all provided by good natural surroundings.

The picture demonstrates how an outside environment can effect a fish's growth. Internal environment is another factor that might influence an animal's growth.

Thus, this can be the complete scenario for the gold fish.
