If two fruit flies, heterozygous for a gene that codes for eye color , were bred together and had 200 offspring , about how many would have the dominant phenotype

Answers

Answer 1

Answer:

75%

Explanation:

Assuming that eye color follows mendellian inheritance, two heterozygous parents would breed as follows:

Ee x Ee

Punnett sqaure

     E     e

E   EE    Ee

e   Ee    ee

All organisms possessing allele E will express dominant phenotype.

Answer 2

From two fruit flies, 75% would have the dominant phenotype.

What do you mean by phenotype?

The phenotype is the set of observable characteristics or traits of an organism. The term covers the organism's morphology or physical form and structure, its developmental processes.

Phenotype refers to an individual's observable traits, such as height, eye color and blood type. A person's phenotype is determined by both their genomic makeup (genotype) and environmental factors.

Examples of phenotypes include height, wing length, and hair color. Phenotypes also include observable characteristics that can be measured in the laboratory, such as levels of hormones or blood cells.

Answers

Answer:

Of the group of bones mentioned, the most proximal is the clavicle, which is part of the shoulder girdle.

Explanation:

Proximal is a reference term used in anatomy to indicate the structures that are closest to the center of the body.

The bones mentioned -clavicle, olecranon, ulna and metatarsals- are related to the function of the limbs. The clavicle is the closest bone to them, located between the neck and the thorax, on each side of the midline of the body.

Regarding the other options, other bones are distal, as they move away from the center of the body. In order from less distal to more distal they are found:

Olecranon, which is a bone eminence of the ulna, in the upper limb. Ulna or cubitus, which is part of the bones of the forearm. Metatarsals are the bones that form part of the foot.

of water. The ecosystem dries up by late summer. What term BEST describes this ecosystem?
A. pond
B. estuary
C. wetland
D. stream bed

Answers

Answer:

The correct answer is C. Wetland.

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.

When you feel cold, there are sensors in your skin that tell the brain you need to warm up. The brain sends messages, by way of nerves, to the muscles in your body causing them to contract and relax very quickly resulting in a shiver. The movement of the muscles during a shiver generates heat which can be used to warm up the surrounding tissues. Which characteristic(s) of life is being represented during this action?
A) respond to stimuli
B) maintain homeostasis
C) growth and adaptation
D) respond to stimuli and maintain homeostasis

Answers

I think it is D because your responding to the cold from stimuli and by creating heat to keep your body the average temperature it is homeostasis.

If a cell does not go through the Sphase of the cell cycle before mitosis, what might be wrong with the daughter cells?

Answers

Answer:

Synthesis is the phase of the cell cycle in which DNA is replicated, occurring between G1 phase and G2 phase. Since accurate duplication of the genome is critical to successful cell division, the processes that occur during S-phase are tightly regulated and widely conserved.

Explanation:

If a cell has not properly copied its chromosomes or there is damage to the DNA, the CDK will not activate the S phase cyclin and the cell will not progress to the G2 phase. The cell will remain in S phase until the chromosomes are properly copied, or the cell will undergo programmed cell death.

Each step in the cell division is controlled and regulated by proteins like Cyclins. If a cell does not go through the S phase, it can not go to the G2 phase until the replication process is completed, or until it's programmed cell death.  

-----------------------------------------------

As the cell passes through different steps of cell division, there are auto control mechanisms to ensure that the step was correctly performed and the cell is ready to go to the next step.  

Many regulator molecules act during the different stages of the mitosis process to make it possible.

There are too many factors interacting, activating, and deactivating to pass from one stage to another.

Cyclins are proteins that regulate the whole cell cycle. There are different types of cycling, each of them acting on a different stage.

When the cell is going through one of the stages, the only cyclin in high levels is the one that is regulating that cycle.

Once that stage is over, that cyclin concentration decreases, and the following one increases.

But if any step was not correctly performed, the cell can not pass to the following one.

During the S stage of the interphase occurs the DNI replication process.

At this point, also occurs the synthesis of histones and other associated proteins.

This is the only stage where the DNI molecule is replicated.

S phase cyclins are in charge of regulating the stage of DNA replication.

If the cell does not go through the S phase, the cyclins of this stage are not activated. And if S phase cyclins are not active, the cell can not go to the G2 phase.  

The cell remains in the S phase until the DNA replication process is correctly done. And if it does not occur, the cell suffer programmed cell death.

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.

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.

During the day, the grape make use of the process, photosynthesis, to get its sufficient food, thus the reason for the slight shrink. But at night, it respire well and new cells are produced. So that its size increase a bit.

Asexual reproduction is defined as the process of reproduction in which only a single parent is involved. Reproduction has been defined as the process carried out by the living organisms and during the process of reproduction the living organisms produces their own young ones and feed them. Reproduction is the supreme quality of living things.

There are two types of reproduction and these are sexual and asexual reproduction. The process of reproduction in which two parents are involved is said to be sexual mode of reproduction and the process of reproduction in which only single parent is involved in known as asexual mode of reproduction. The example of asexual reproduction are budding, fragmentation, spore formation, and binary fission.

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
