When a dark blue fish and a light blue fish with dark blue fins were mated , all offspring became dark blue. What could also be seen was that part of the offspring got light gray fins.Explain with the help of genetics why all fish turn dark blue.

Answers

Answer 1

Answer:

The allele for dark blue fish must be dominant and the dark blue parent fish must be homo-zygous dominant;

This would mean the dominant allele would necessarily be inherited by all offspring and since it is dominant, it would be expressed over the other allele (light blue fish)

Postganglionic sympathetic axons are carried from the sympathetic trunk to all spinal nerves through ______.

Answers

Answer:

gray rami communicantes

Explanation:

Postganglionic sympathetic axons are carried from the sympathetic trunk to all spinal nerves through gray rami communicantes. The sympathetic nervous system is almost connected to all parts of the body.

What is the nervous system?

The nervous system is made up of neurons that are connected to each other and send the message for action to different parts of the body. The whole nervous system of the body is divided into three parts: the central nervous system, the peripheral nervous system, and the autonomic nervous system.

The central nervous system is composed of the brain and spinal cord, while the autonomic nervous system is composed of the sympathetic and parasympathetic nervous systems. The peripheral nervous system includes the nerves of the brain and spinal cord that are derived from these two organs. The sympathetic nervous system activates the majority of the organs in times of danger, whereas the parasympathetic nervous system is associated with rest.

Hence, Postganglionic sympathetic axons are carried from the sympathetic trunk to all spinal nerves through gray rami communicantes.

What are some ways that the biosphere interacts with the other three systems?

Answers

Answer:

Plants (biosphere) draw water (hydrosphere) and nutrients from the soil (geosphere) and release water vapor into the atmosphere. Humans (biosphere) use farm machinery (manufactured from geosphere materials) to plow the fields, and the atmosphere brings precipitation (hydrosphere) to water the plants.

Explanation:

Answer :Full Answer. A classic example of an interaction between spheres is when a plant (part of the biosphere), takes carbon dioxide from the atmosphere and water (the hydrosphere) through its roots from underground (geosphere) to perform photosynthesis, which provides the plant with food and releases oxygen into the atmosphere.

What flower has an ugly bud but a beautiful blossom?

Answers

Explanation:

Caladiums are tropical to sub-tropical plants grown mainly for their exquisite, colorful leaves. These foliage plants occasionally have a surprise up their metaphorical sleeve. Blooming on caladium plants isn’t common, but tubers planted in favorable locations tend to produce small flowers. These inflorescences aren’t as impactful as a rose or dahlia but have their own charm and, sometimes, a strong pleasant scent. There are several schools of thought on what to do with caladium flowers. While some growers believe pinching them off helps force energy to the tubers, others leave the small blooms with no ill effect on the plant.

In terms of structure and function how do the vacuoles in a typical plant cell compare to those of a typical animal cell

Answers

Answer:

Vacuoles in animal cells do NOT help the cell take its shape, however, in plant cells, vacuoles are larger, and DO affect the shape of the cell.

The function of the vacuole in plants is different from that in animals, as the vacuole in animals is smaller, while in plants it is larger and pushes the nucleus to one side while consisting of water and other materials.

What is the significance of the vacuole in plants and animals?

Vacuoles are cell organelles found in both plants and animals, in plants, vacuoles are large, fluid-filled structures that occupy a large portion of the cell, and they perform several important functions, including storing water and helping to maintain the shape of the cell, while in animals, vacuoles are smaller and less in number than in plants, as they have a variety of functions, like storing waste materials, etc.

Hence, the function of the vacuole in plants is different from that in animals, as the vacuole in animals is smaller, while in plants it is larger and pushes the nucleus to one side while consisting of water and other materials

Suppose that a patient is diagnosed with a new disease caused by the buildup of waste material in the body's cells. Which organelle is most likely malfunctioning in the patient's cells?

a) Golgi apparatus.
b) lysosome.
c) ribosome.
d) endoplasmic reticulum.​

Answers

Lysosome organelle is most likely malfunctioning in the patient's cells (option b),.

The organelle most likely malfunctioning in the patient's cells is the lysosome. Lysosomes are membrane-bound organelles that contain enzymes responsible for breaking down waste materials, cellular debris, and foreign substances. They play a vital role in cellular waste disposal and recycling.

In this case, the patient is diagnosed with a disease caused by the buildup of waste material in the body's cells. This suggests that there is a problem with the breakdown and disposal of waste materials within the cells.

The Golgi apparatus is responsible for modifying, sorting, and packaging proteins for transport within or outside the cell. It is not directly involved in waste material breakdown.

Ribosomes are responsible for protein synthesis and are not directly involved in waste material breakdown either.

The endoplasmic reticulum (ER) is involved in protein synthesis, lipid metabolism, and detoxification. However, its dysfunction would not directly result in the buildup of waste material in the cells.

Therefore, considering the role of lysosomes in waste material breakdown, it is most likely that the malfunctioning organelle in the patient's cells is the lysosome. This malfunction would lead to the accumulation of waste material, causing the disease symptoms.

what was the key factor that allowed Hershey and Chase to show that DNA alone carried the genetic information of a bacteriophage?

Answers

Explanation:

DNA contains phosphorus, but protein does not. Protein contains sulfur, but DNA does not. This allowed radioactive phosphorus and radioactive sulfur to identity each molecule specifically.

[tex] \mathbb \fcolorbox{green}{red}{ STAY \: STRONG}[/tex]

[tex] \mathfrak \fcolorbox{green}{red}{BE \: BRAINLY }[/tex]

In the DNA  structure there is phosphorus present while protein does not contain phosphorus but it contains sulfur while DNA does not which allowed radioactive phosphorus and radioactive sulfur to identity each molecule specifically.

What is Hershey and Chase experiment?

Hershey-Chase experiment was the final experiment which is also called as the Waring Blender experiment. In this experiment, they showed that phages only injected their DNA into host bacteria, and that the DNA served as the replicating genetic element of phages.

They used this experiment to prove that DNA is the genetic material. [tex]T_2[/tex] Bacteriophage that was grown in isotopic medium radioactively labels a specific viral component. Two types of isotopic media were used.

Viruses that were grown in radioactive sulfur (35S) contained radiolabeled proteins.Viruses grown in radioactive phosphorus (32P) had radiolabeled DNA

Next, the virus was allowed to infect a bacterium (E. coli) and the virus and bacteria were then separated through centrifugation. After centrifugation, the larger bacteria formed a solid pellet, while the smaller viruses remained in the supernatant. The pellet of bacteria was found to be radioactive when infected with 32P-virus (DNA), but not with 35S-virus (protein).

This provided proof that DNA was the genetic material because DNA had been transcribed into bacteria, not proteins.

Thus, in the DNA  structure there is phosphorus present while protein does not contain phosphorus but it contains sulfur while DNA does not which allowed radioactive phosphorus and radioactive sulfur to identity each molecule specifically.

Why is ATP known as the energy currency?
5 line answer plz

Answers

Answer:

ATP is commonly referred to as the "energy currency" of the cell, as it provides readily releasable energy in the bond between the second and third phosphate groups. ... As a result, cells within the human body depend upon the hydrolysis of 100 to 150 moles of ATP per day to ensure proper functioning.In addition to providing energy, the breakdown of ATP through hydrolysis serves a broad range of cell functions, including signaling and DNA/RNA synthesis. ATP synthesis utilizes energy obtained from multiple catabolic mechanisms, including cellular respiration, beta-oxidation, and ketosis.                

  Explanation: is this good enough?

Answer:

Because its a sequence in which molecules can store their own energy and use it when needed such as in a chemical reaction , note that this is the main reason some molecules stay dormant during a chemical reaction and that is because they didn't use ATP

Explanation:

The principal molecule for storing and transferring energy in cells. It is often referred to as the energy currency of the cell and can be compared to storing money in a bank. ... AMP can then be recycled into ADP or ATP by forming new phosphoanhydride bonds to store energy once again. (This Is A Web Response) but feel free to use mine if it helps its a more simpler term.

A cross between two mice with long tails and brown fur produced the four types of offspring as listed.
• Long-tailed with brown fur
• Long-tailed with white fur
• Short-tailed with brown fur
• Short-tailed with white fur
Which genetic mechanism best explains the results of this cross?
A independent assortment
B. Crossing-over
C. gene linkage
D. dependent assortment

Answers

Answer:

B

Explanation:

The genetic mechanism that best explains the results of this cross is independent assortment. The correct option is A.

What is independent assortment?

According to Mendel's law of independent assortment, alleles from two (or more) different genes are sorted into gametes independently of one another.

In other words, the allele received by a gamete for one gene has no effect on the allele received for another gene.

Independent assortment occurs when alleles from at least two genes are assorted into gametes independently.

As a result, the allele inherited by one gamete has no effect on the allele inherited by the other gametes. Mendel observed that the transmission of various genes appeared to be separate events.

Independent assortment is the genetic mechanism that best explains the results of this cross.

Thus, the correct option is A.
