If a red-eye female fly is crossed with a red-eye male fly, could they produce offspring with white eyes? Briefly explain your answer. Your answer must include a Punnett square that proves your answer.

Answers

Answer 1

If the red-eye parents are homozygous, no. But if the red-eye parents are heterozygous, yes.

Monohybrid crossing

We are assuming that the red-eye trait is dominant over the white-eye trait. If two red-eye parents are crossed with one another, whether they could produce white-eye offspring would depend on the zygosity level of the parents.

Assuming that red-eye is R and white-eye is r. If the two parents are homozygous red-eyed, their genotypes would be RR. Crossing the two:

       RR    x     RR

   RR   RR   RR   RR

All the offsprings would be RR and there is a zero chance of producing a white-eye offspring.

Now, assuming that the two parents are heterozygous:

        Rr    x    Rr

     RR   Rr   Rr   rr

Both RR and Rr are red-eyed while rr is white-eyed. The Punnet's square for the cross can be found in the attached image.

In other words, it will only be possible for the two red-eye parents to produce white-eye offspring if they are both heterozygous. Any other genotype will give a zero chance of white-eye offspring.

Compare transitional aquatic ecosystems. Identify two types in the organizer below and describe the environments each type combines. 9th grade Biology

Answers

Answer:

The correct answer is -

wetlands - land and water

estuaries - freshwater  and salt water

Explanation:

There are three types of aquatic ecosystems that are lentic, lotic, and wetlands. Lentic ecosystems include slow-moving or non-moving water systems like pools, lakes, or ponds. The Lotic system on the other hand is aquatic systems with faster-moving water systems like the ocean or river also known as estuaries.

Wetlands are the system that has unique properties of having vegetation adapted according to the condition or situations on the water in saturated soil flood with water seasonally or permanent.

Photosynthesis/CR definition

Answers

Answer:

Photosynthesis is the process in which green plants and some other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

Cellular Respiration is the process through which cells convert sugars into energy. To create ATP and other forms of energy to power cellular reactions, cells require fuel and an electron acceptor which drives the chemical process of turning energy into a useable form.

Students in a science class visited four local ecosystems. The students observed the species present in each ecosystem and recorded their observations in the table.


Based on these observations, which ecosystem is likely to be the least sustainable?

A.Ecosystem 1, because it has the fewest species
B.Ecosystem 2, because it includes both aquatic and terrestrial species
C.Ecosystem 3, because it has few predators
D.Ecosystem 4, because it supports many animals

Answers

the answer is A

this is because in ecosystem 1 there are only predators and no other species are observed. therefore predators have less food to eat thus they will die of hunger or move to another ecosystem

This is because in ecosystem 1 there are only predators and no other species are observed. therefore predators have less food to eat thus they will die of hunger or move to another ecosystem.

What is Ecosystem?

An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life.

Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts. Biotic factors include plants, animals, and other organisms. Abiotic factors include rocks, temperature, and humidity.

Every factor in an ecosystem depends on every other factor, either directly or indirectly. A change in the temperature of an ecosystem will often affect what plants will grow there, for instance.

Therefore, This is because in ecosystem 1 there are only predators and no other species are observed. therefore predators have less food to eat thus they will die of hunger or move to another ecosystem.

The hypoxic zone in the Gulf of Mexico is not unique; at least 200 dead zones exist at estuaries and along seacoasts worldwide. These low-oxygen regions share many of the same causes, and they all have ecological and economic repercussions for ecosystems and people. Fortunately, we can pursue strategies to lessen the number, severity, and impacts of dead zones. The following list includes examples of factors that contribute to the development of dead zones (the cause), the consequences that result from dead zones, and possible solutions. Which of the following are consequences of dead zones?

a. Economic losses for fisher's
b. Death or aquatic organism that cannot escape
c. Policies to promote no-till agriculture
d. Construction of wetlands to absorb nutrients
e. Nutrient runoff from agriculture fertilizers, manure, and urban sources, which leads to rapid algal growth and subsequent bacterial decomposition

Answers

Answer:

Answer:

e. Nutrient runoff from agriculture fertilizers, manure, and urban sources, which leads to rapid algal growth and subsequent bacterial decomposition

Answer:

 Explanation:

Run off from agricultural wastes which contain Nitrogen and Phosphorus are the major sources  causes dead zones.The process where these chemical get washed into the aquatic bodies is called Eutrophication.

These substances leads to algae boosts in the water.The increases population of the algae consumes the available oxygen in the water, therefore making the oxygen concentration drops or no oxygen at all;(Hypoxia)

As the algae population feed on the available resources in the water they exhausted this,and later die.

When the decomposing bacteria used the oxygen in the water to breakdown the dead algae they make use of the available oxygen.This further reduced the oxygen availability and therefore   reduces the oxygen and hence the zone becomes the dead zone, because little or no oxygen is available  for survival of organisms.

This is reversible if the process if europhication or other causes  is eliminated

Grapes growing on a vine are observed to shrink slightly during the day and increase in size at night. This is because:
a. developing fruits, such as grapes, transpire a lot of water to stay cool.
b. photosynthesis to produce sugar occurs in the light, but respiration and, therefore, the growth of new cells occurs mostly in the dark.
c. in leaves, phloem flow to growing sinks only occurs when the stomata are closed, because the transport capacity of the xylem is too small to supply water for both transpiration and phloem flow.
d. during the day, transpiration pulls on the water in the whole plant, causing the grapes to shrink slightly.

Answers

Answer:

b. photosynthesis to produce sugar occurs in the light, but respiration and, therefore, the growth of new cells occurs mostly in the dark.

Explanation:

Photosynthesis is the means by which green plants produce their foods by the use of sunlight, chlorophyll and carbon dioxide.

Explanation:

A wetland is a generic name for habitats located between hard ground and open water. Wetlands include, for example, wet and waterlogged shallow land, shallow lakes and seas, marshes, floodplain forests, and flowing waters.

Wetlands provide a breeding ground for many animal and plant species and can act as a buffer in flood areas and prevent severe and sudden floods. Rainfall, waters entering the catchment area, soil and ground elevation differences in the area, and water evaporation form the hydrological conditions of the wetlands. Wetlands are one of the most valuable and endangered habitats on Earth. Swamps, overgrown lakes, flood-prone areas, shallow bays, water-covered beach areas and mangrove beaches are all endangered habitats.
