Answer:

2/4 or 50%

Explanation:

Heterozygous means the organism has two different alleles, so the genotype of the woman is Xx

The mutant's genotype is xx, because in order for a recessive trait to be expressed, there needs to be two recessive alles

Use the genotypes of the parents to create a punnett square (shown in image) to find the possible genotypes of their children

To chance of a phenotype is determined by how many of the possible genotypes will express the phenotype of x-ray vision and how many genotypes there are in total. The chance can be presented like this:

2/4

2 is the number of x-ray children

4 is the total number of children

To find the percentage you can do 2 ÷ 4 × 100

And that will give you the answer of 50

So the percentage is 50%

The advantage of selective breeding is​ the ability to produce offspring with more desirable traits. Therefore, option A is correct.

Choosing parents with specific traits to breed with one another in order to generate kids with more desired traits is known as selective breeding. For thousands of years, humans have carefully bred a variety of animals and plants, including crop species that produce more.

Through artificial selection, several fruits and vegetables have been enhanced or even created. For instance, selective breeding was used to create broccoli, cauliflower, and cabbage from the wild mustard plant.

offspring can be produced with more desirable characteristics by selective breeding. Therefore, option A is correct.

Sensory neuron(s) then transmit information from the sensory receptor(s) to the Central Nervous System

Explanation:

These receptors are located all over the body but some types of receptors are in specific areas of the body (e.g. taste receptors in the mouth).

Sensory neuron(s) then transmit information from the sensory receptor(s) to the Central Nervous System (i.e. the brain and spinal cord, sometimes referred to in the abbreviated form: C.N.S.). This is happens because peripheral nerves all connect to the spinal cord via the network of nerves within the nervous system.

The information so received by the C.N.S. is further transmitted by relay neurone(s) with the C.N.S.

When a parent cell splits to create two identical daughter cells, the process of the nuclear division known as mitosis takes place in eukaryotic cells.

What is meant by mitosis?

DNA, a molecule found on chromosomes, is the genetic information carrier. They are linearly arranged genes that are present in couples in the cell's nucleus. Genes also are arranged in pairs, and each pair produces a coding that results in the production of a distinct protein.

Mitosis is a sort of cell division that makes sure each new daughter cell formed when a cell splits possess the same genomic structure.

Two cells referred to known as daughter cells are created during mitosis. Any newly formed daughter cells must have genetic material that is similar to that of the parent cell, and the number of chromosomes must stay constant.

Therefore two identical daughter cells are produced as a result of mitosis.

Answer:

Explanation:

Artificial selection selects the traits that are already present in the animal or human. On the other hand genetic engineering creates new/different traits.

In artificial selection scientist only breed the desirable traits. With genetic engineering use DNA to specifically manipulate the genome. Example: A way to change the genome is to enter genes from another organism.

Answer:

Earth is at the center

Includes five planets.

The orbits of the planets are circular,

The Sun is at the center of the solar system.

The orbits of the planets are elliptical

Includes eight planets.

The solar system

Explanation:

The main difference between the heliocentrical and geocentrical model is that in the first one, the Sun is in the center and the planets are around it, while in the second model, the Earth is in the center and the Sun, the moon, and the planets are around it.

Also, the geocentrical model stated that there were five planets, Mercury, Venus, Mars, Jupiter, and Saturn. These planets had circular orbits. In other words, they have a circular motion around the Earth, and this one was still in the center of the system.

In the heliocentric model, there are eight planets, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune, and they all rotate in elliptical orbits around the Sun. The Heliocentric model is also called the solar system since its central star is the Sun, and the planets are around it.

Answer:

D

Explanation:

The wave's speed increases when air temperature increases. Therefore, option (D) is correct.

As air temperature increases, the speed of sound waves in air also increases. This is because air molecules move more quickly at higher temperatures, and the faster-moving molecules can transmit the sound energy more quickly. As a result, sound waves will travel faster through hot air than through cold air.

Conversely, as air temperature decreases, the speed of sound waves in air will decrease as well. This property of sound waves can have practical implications, such as in designing concert halls or sound systems where the temperature of the air needs to be taken into account in order to achieve optimal sound quality.

Answer: Asthma is one of the most frequent chronic conditions in Europe, affecting more than 30 million Europeans – a number that is still growing.

"At some stage in the future almost half of the population may suffer from an allergic disease and asthma will be a considerable proportion of this," said Nikolaos Papadopoulos, professor of allergy and pediatric allergy at the University of Athens, in an interview. He added that it is also a global phenomenon.

Asthma is a chronic disease of the airways that makes breathing difficult. An asthma attack inflames and narrows the airways that carry oxygen to the lungs, leading to coughing, wheezing, shortness of breath, and chest tightness. Its prevalence has been linked to industrial development.

The statement which is not true of the purpose of the alcohol in Gram staining is as follows:

Thus, the correct option is A.

Gram staining may be defined as a methodology that is utilized for the classification of bacterial species such as gram-positive and gram-negative.

In gram staining, ethyl alcohol or acetone is used as a decolorizer that dehydrates the peptidoglycan layer. It involves the shrinkage or tightening of the cell wall.

In this process, the large crystal violet-iodine complex is not able to puncture this tightened layer of peptidoglycan.

Answer:

In the follicular phase, the follicles grow inside the ovary. The ovulatory phase is the time of greatest fertility for women. In it, estrogen levels peak just before the egg is released. In the luteal phase, after ovulation the follicular structure that remains in the ovary reorganizes and becomes a gland known as the corpus luteum. The self-determined life of the corpus luteum causes it to degenerate after 14 days and end a menstrual cycle. At the end of the luteal phase, progesterone and estrogen levels drop and menstruation occurs.

Explanation:

The follicular phase is where follicles develop (fluid-filled cavities in the ovary that contain an undeveloped egg) that will eventually house the egg. For the development of follicles, the body sends a signal to the brain to start the production of follicle stimulating hormone (FSH), the follicles begin to develop and produce estrogen. In the ovulatory phase, the level of estrogen in the body continues to rise, causing a rapid rise in LH. This increase causes the secretion of proteolytic enzymes that will degrade the follicular tissue allowing the maturation process of the ovum and its release to finish, a fact known as "ovulation". Ovulation usually occurs between 24 and 36 hours after the LH surge, so luteinizing hormone is a good factor for measuring the period of maximum fertility and knowing the fertile days of the woman. In the luteal phase, the corpus luteum develops that will last until a possible pregnancy or menstruation occurs, starting the next cycle. The egg, after being released, travels through the fallopian tube to the womb. It can survive up to 24 hours and sperm up to 5 days inside the uterus, therefore the days before ovulation and the day of ovulation itself, which can be calculated with the ovulation calendar, are those of maximum fertility and higher chances of pregnancy. After ovulation, the follicle begins to contract but continues to produce progesterone and begins to produce estrogen in order to continue preparing the uterus to receive the embryo.
