Zac and nina are studying for a psychology test. zac states that heritability refers to the extent to which genes are responsible for an individual's level of a particular characteristic is genetic. nina disagrees, stating that heritability refers to the extent to which genes are responsible for variation among individuals in a particular characteristic. which student is correct

Answers

Nina has the correct answer. Heritability is actually the extent to which the genes are responsible for the variation among individuals in a particular characteristic. Specifically, it is a figure that determines the rate of variation in a single phenotypic trait in a population with regard to the genetic variation. 
Final answer:

Nina is right. Heritability doesn't define how much of a character trait is genetic, it explains the extent to which genes cause variations in that specific trait among a population.

Explanation:

In this scenario between Zac and Nina, Nina is the correct one. Heritability does not exclusively define how much of an individual's characteristic is due to their genes. Rather, heritability explains the variation or differences we see among individuals within a population. For example, if we were studying height among a group of people, heritability would refer to how much of the variation in height is due to genetic factors versus environmental factors.

Which of these connections are used for camcorders, dvd players, and gaming consoles?

Answers

The FireWiire is connection used for camcorders, DVD players, and gaming consoles. The standard that defines the FireWire connection is IEEE 1394. IT  is an interface standard for a serial bus for high-speed communications and isochronous real-time data transfer.


Final answer:

Camcorders, DVD players, and gaming consoles often use HDMI for modern devices, with Component Video, Composite Video, and S-Video being options for older devices.

Explanation:

The connections that are typically used for devices such as camcorders, DVD players, and gaming consoles include HDMI (High-Definition Multimedia Interface), Component Video (YPbPr), Composite Video (RCA), and S-Video. However, the most common connection used in modern devices is HDMI, which provides high-quality digital video and audio through a single cable. Older devices or those requiring analog input might use Component, Composite, or S-Video connections. It is important to select the correct type of cable to match the ports available on both the device and the display (TV or monitor) to ensure compatibility and the best possible quality of the media.

A direct indication that the white blood cells of the body are functioning would be

Answers

A direct indication that the white blood cells of the body are functioning would be a decrease in the number of pathogens in the body 

The immune system of a person is capable of fighting with infectious microorganisms and can easily protect the body from infectious diseases. This condition indicates that the white blood cells are functioning properly.

Further Explanation:

The foreign particles can be either microbial pathogens or dust particles and pollens. Depending on the type of foreign body, the innate immune system functions. The physical barriers like skin, mucous membranes, and lungs help in preventing foreign particle entry. The pathogens are removed by the action of immune cells called white blood cells (monocytes, macrophages, dendritic cells, mast cells, and polymorphonuclear leukocytes). In a healthy individual, the total WBC (white blood cell) count ranges between 4,500 to 11,000/. When an infection is caused, or the person has some allergy, this count is increased.

The effective immune system is fighting with any microorganism or damage that can efficiently protect the body by releasing certain chemicals. The damaged host cells also release certain chemicals (vasoactive factors) like histamine, prostaglandins, and bradykinin. This causes the movement of the fluid in the extracellular spaces. All these factors cause an increase in blood flow and fluid retention (that cause edema). The increased vascular permeability helps the WBCs to reach that area easily.The neutrophils that are delivered to the inflammation site phagocytize microbes and kill it.

What hormonal change occurs after fertilization that causes the endometrial lining to remain intact so that the fertilized egg can successfully implant in it?

A. The pituitary gland secretes oxytocin, which maintains the endometrial lining.

B. The pituitary gland secretes follicle stimulating hormone, which acts on the follicles and stimulates them to produce progesterone.

C. The hypothalamus secretes gonadotropin releasing hormone, which maintains the endometrial lining.

D. The developing embryo secretes human chorionic gonadotropin, which prevents the corpus luteum from disintegrating.

E. The developing embryo takes over the production of progesterone after the breakdown of the corpus luteum to maintain the endometrial lining.

Answers

The correct option is B.
For a mature woman, each month the increased level of estrogen hormone leads the pituitary gland to secrete luteinizing hormone. Once this hormone is secreted, the ovary releases a single egg which moves down to the lining of the uterus. If fertilization does not occur, the egg is shed together with the lining of the uterus in a monthly process called mensuration. If fertilization occur, then the fertilized egg attach to the lining of the uterus and placenta is formed. The fertilized egg then send signal to the ovary to keep secreting progesterone, which will sustaining the pregnancy by keeping the uterus lining thick and nourishing for the developing embryo.

Answer:

B. The pituitary gland secretes follicle stimulating hormone, which acts on the follicles and stimulates them to produce progesterone.

What might cause a virus in the lysogenic cycle to suddenly enter the lytic cycle?

Answers

stress of host cell, the host cell needs to be weak enough for the virus to make vital orgenells to function

Answer:

The correct answer would be the "stressful conditions of the host cell."

In the lysogenic cycle, the viral genome gets attached and integrated into host cell chromosomes and the virus becomes dormant and is termed as a prophage.

However, environmental stress to the host cell such as exposure to a toxic substance, starvation et cetera may cause the prophage to be excised which then enters the lytic cycle.
