In a living organism, at which stage does segregation of gene pairs takes place?

Biology
2 answers:
Bess [88]3 years ago
7 0

Answer:

The correct answer will be- Meiosis anaphase I and II.

Explanation:

The segregation of gene pairs usually takes place during the gamete formation which is formed by the meiosis.

During anaphase I and II, the chromosome containing the genes which determine the traits of an organism gets separated reaching the opposite poles of the cells through mitotic spindles.

The segregation of gene plays an important role in determining the trait of the organism as the alleles show their effect only when they come in pairs after fertilization.

Thus, Meiosis anaphase I and II is the correct answer.

The answer to this question is gamete formation. During meiosis, the DNA is only replicated or copied once even if the cell is divided into four different cells. The formation of gamete segregates the gene pairs among the new cells.

<h3>What is Anthropology?</h3>

The study of what makes humans human is known as anthropology. Holism refers to anthropologists' comprehensive approach to comprehending the many distinct elements of the human experience. They use archaeology to learn about how human cultures lived hundreds or thousands of years ago and what was significant to them. They look at our biological bodies and genetics, as well as our bones, food, and overall wellness. Even though nearly all humans require the same things to thrive, such as food, water, and company, the ways in which these requirements are met might vary greatly.

Explain the characteristics of this soil sample that likely allowed Darren to make this identification. Include particle size an
Mekhanik [1.2K]

Answer: Clay, sand and silt characteristics

Explanation:  I found the picture and the rest of your question.

Soil identification as sandy clay

Soil Texture indicates the composition of that soil by which it shows the amount of clay, sand, and silt.

That is a classification instrument and it's used in laboratories to show soil classes. This identification is showing soil class by the characteristics of silt, clay, and sand.

Soil texture can be defined by feel method or hydrometer methods for example.

Characteristics:

  •  0% to 28% of Silt
  •  80% to 45% of Sand
  •  20% to 35% Clay

pishuonlain [190]

When you are exposed to bright light, cells in the retina detect the stimulus and send it to the brain for processing. The brain commands the iris to constrict and decrease pupil size.

The structure that serves as a receptor in this system is Retina

<h3>How can we see the object?</h3>

Organisms adapted and evolved the eyes to see the surrounding environment. This ability to see begins when the visible wavelength of light enters the eye through a transparent covering called Cornea. The light enters the cornea and enters the inner of the eye through a round hole known as the pupil.

The light rays then enter the convex-shaped lens in the eye which focuses the beam of light on the back of the eye in the region of the tissue called the retina. The retina contains the photoreceptor cells-rods and cones in which the cone cells have the ability to detect three wavelengths of light especially blue, green and red which help us see various versions of the colour.

These cells convert light energy to chemical energy in the form of the action potential which gets transmitted to the part of the brain associated with the vision. This completes the pathway of the vision.

Thus, Retina is the answer.

marta [7]
The appropriate response is hydrogen bonds. Fever is an adjust of gainful and destructive impacts. High fevers can have a tendency to skew the adjust toward the destructive. 
The reality of the matter is that protein optional structure (generally hydrogen bonds) start to denature when moving toward 41 degC (106 degF), however energy likewise change. Energy is a quite major ordeal, even a little temperature move can altogether affect the speed of a response or connection.
