Karyotypes can be studied to determine an organism’s chromosomal makeup and to detect genetic defects. Turner syndrome occurs when a female has an incomplete set of sex chromosomes. Symptoms of Turner syndrome include swollen hands and feet, short stature, and infertility. Which type of chromosomal mutation is responsible for causing Turner syndrome

[ad_1]

Aneuploidy is the type of chromosomal mutation that is responsible for causing Turner syndrome.

Aneuploidy is a type of chromosomal mutation in which there is presence of an abnormal number of chromosomes in a cell. The chromosomes may be incomplete (missing) or excessive (extra). For example, if a human cell had 42 sex chromosomes instead of 46, or it had 48 chromosomes instead of 46, it is said to be anueploidic in nature. Aneuploidy occurs during cell division when there is improper separation of the chromosomes between the two cells. Aneuploidy is responsible for many genetic disorders including Turner syndrome.

The _____ approach to psychological disorders primarily focuses on the brain, genetic factors, and neurotransmitter functioning as the sources of abnormality.

[ad_1]

1. The answer is “C”.

“Identical twins” who have been raised apart are typically more similar in intelligence level than biological siblings raised together because they have been born with the same genetic code.

Identical twins originate from a single fertilized egg that parts into two. Before it parts, it is either male or female. After it parts, there are either two guys or two females. The two sections of the fertilized egg embed in the uterus and every create one of the twins.  

Identical twins have the equivalent hereditary source. No immediate reason for monozygotic twinning has been resolved; it isn’t innate. Monozygotic twins speak to around 33% all things considered. They may look strikingly comparative, and it might be hard to reveal to them separated.

Lawrence Kohlberg felt that the best way to support development through these stages was by discourse of good problems and by investment in consensus democracy inside small groups. Consensus democracy was rule by understanding of the gathering, not larger part rule. This would invigorate and widen the reasoning of youngsters and grown-ups, enabling them to advance starting with one phase then onto the next.

3. The answer is “D.  showing a learner how to correct common mistakes”.

The term scaffolding alludes to a procedure in which instructors display or exhibit how to take care of an issue, and afterward venture back, offering support as required. Analyst and instructional architect Jerome Bruner first utilized the term ‘scaffolding’ in this setting, harking back to the 1960s.

Biodiversity enhances ________ because it provides genetic diversity and the potential for developing more productive food crops that are disease resistant and adaptive to drought.

[ad_1]

In tropical rain forest, the animals will have to deal with higher temperatures and greater rainfall. One example of an adaptation they might need is a thin, water-proof coat. This will prevent heat from becoming trapped inside their fur/hair/feathers, and the water-absorbing coating will allow water to stick to the inside of the coat without being absorbed, where the water will absorb the heat instead of themselves, and will cool the through evaporative cooling (heat release through evaporation)

In a deciduous forest, there is much colder temperatures, and significantly less rainfall. These animals would likely want a thicker water-proof coat. This is because the thicker coat would allow heat to become trapped, keeping them warm in the winter, and the water-proof coating prevents water from freezing in their fur, making them colder.

[ad_1]

There are two systems in the human body that are responsible for the coordination between the functions of different systems to achieve the unity of the living organism’s body. These two systems are the nervous system and the endocrine system. The action of the nervous system is fast and takes a short time, while the action of the endocrine system is slow and takes a long time.

The functional unit of the nervous system is the nerve cell or the neuron. The neuron consists of a cell body and the axon. The cell body starts with the dendrites that receive the messages or the impulses from other neurons or from different sense organs or receptors. These impulses are then transmitted through the cell body. The cell body contains a nucleus and different organelles which help the nerve cell to perform its functions. The nerve impulse is then transmitted to the axon.

The axon is an extension from the cell body. There are some cells called Schwan cells that secrete a myelin sheath to insulate the axon from the surrounding medium. The insulated axons have more ability to conduct the impulses than non-insulated axons. The axon ends with the terminal arborizations. The terminal arborizations of a nerve cell connect to the dendrites of the next cell or to the afferent organ. The gaps between the dendrites and the terminal arborizations are called the synapses.

The nerve impulse is an electrochemical phenomenon i.e. an electrical phenomenon with a chemical nature. The membrane of the axon acts as a barrier between an outside positively charged medium and an inside negatively charged medium. This makes a potential difference of  -70mV. This state is called the resting potential. When the membrane is subjected to a stimulus, the positive charges enter to inside and the negative charges exit to the outside. The potential difference now becomes +40mV. This state is called the depolarization state. The point of stimulation acts as a new stimulus for the next point and so on. The membrane sooner gains its permeability again and the positive charges return to the outside and the negative charges to inside. This state is called repolarization.

The nerve impulse reaches the synapse. There are some neurotransmitters that are excited by the nerve impulse coming and carry the message across the membrane. Some receptors receive theses neurotransmitters on the dendrites of the next neuron. These receptors act as a stimulus for the new cell.

The correct answer to this would be:

“inability of many medium ground finches to feed on large,
hard seeds”

The medium ground finches feed on seeds. However, the birds
have two variations in the bill shape: some birds have wide, deep bills while others
have thinner bills. The large-billed birds feed more proficiently on large,
hard seeds, while the smaller billed birds feed more proficiently on small,
soft seeds. The reduction in number started in 1977, when a drought period
altered vegetation on the island. Due to this event, the number of seeds
declined dramatically; the decline in small, soft seeds was larger than the
decline in large, hard seeds. The large-billed birds were able to endure better
than the small-billed birds thus resulting in decline in number.

Which statement about inheritance is true? Girls get most of their traits from their moms; boys get most of their traits from their dads. Male offspring will always have an X-linked genetic disease if the mom is a carrier. Fathers always determine the gender of the offspring in humans. Males never have Y chromosomes.

[ad_1]

The correct answer is option Fathers always determine the gender of the offspring in humans.

In case of the humans, the females have two X chromosomes and the males have one X and one Y sex chromosome. So, the female always contribute X chromosome to the gamete. The female always produce the same type of gamete in any case. The males either pass X chromosome or the Y chromosome. In case, the gamete with the X chromosome fuses with female gamete than the progeny would have XX chromosome and will be a female. In case, the gamete with the Y chromosome fuses with female gamete than the progeny would have XY chromosome and will be a male. Hence, teh fathers determine the gender of the child.

How does genetic drift affect the survival of an organism?

[ad_1]

Well which one tends to live around deep waters like the open ocean?

Frogs are amphibians, meaning they need land. The open ocean does not have land.

Dolphins live in and travel around the ocean, not needing land and capable of swimming great depths so they are capable of living in the open ocean.

Alligators live in areas with shallow waters where they can cool down and hide to capture unsuspecting prey. They need to breathe every now and then and even though they are fantastic swimmers in rivers, they can’t go too deep. They also need land to lay their eggs and mate, so the open ocean is not the best option for an alligator.

Hippopotami also live in shallow water like alligators. And like alligators, they need to breathe every now and then and they can’t go too deep in water. Rivers are great for them, but they won’t last too long in an open ocean.

Thus, the organism most likely adapted to the open ocean are dolphins.

Answer:

The process in which process do producers use carbon from carbon dioxide to produce other carbon-containing molecules is the Photosynthesis.

Explanation:

Photosynthesis is the process of making food by plants.

To make it, plants need chlorophyll, which is a green pigment that they have on the leaves. It is responsible for absorbing adequate light to perform this process.

This process is performed on the leaves, which are oriented towards the light. The chlorophyll of the leaves capture the sunlight. From the sunlight and carbon dioxide, the raw sap is transformed into processed sap, which constitutes the plant’s food. In addition the plant produces oxygen that is expelled by the leaves.
