A male with hemophilia (recessive, sex-linked) and a female who is normal (no hemophilia) have a girl? What is the likelihood that a girl will have the disorder?
a - 0%
b - 50%
c - 100%
d - Impossible to tell
Answer:
Option A is the correct answer.
- 0%
Explanation:
This is because the male is hemophilia recessive, not dorminant and the female allele has no traits of hemophilia therefore, the offspring have zero percent of having the diseases. The girl allele will be normal and recessive of hemophilia. Because there is no dorminant allele that can result into hemophilia.

An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life. Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts.
Healthy ecosystems clean our water, purify our air, maintain our soil, regulate the climate, recycle nutrients and provide us with food. They provide raw materials and resources for medicines and other purposes.

A young child does something he knows is wrong and immediately looks at an adult for a reaction. This child has learned to?
Answer:
This child has learned to act from its adults.
Explanation:
This child has learned to act according to the reaction of the adult. If a child done something wrong and the adult reaction is not good the child will not repeat it because he knows that this act is bad while on the other hand, when the child done something good and the adult gives a good reaction so the child will continue doing this action so we can say that a child learn most of the things from their adults.

Gametes (sex cells) in the flower require nutrients from the soil to ensure proper functioning. Which list of systems below best describes the interaction in that statement?
Answer:
There is a great interaction between reproductive stage and absorption of nutrients.
Explanation:
Good interaction of reproductive stage and absorption of nutrients from the soil is very important for producing good and healthy flowers because reproductive stage needs nutrients. If these nutrients can't available in the soil so the plant produced less flowers and as a result less seeds are produced in the end of this reproductive stage so we can say that reproductive stage and absorption of nutrients has a great interaction between each other.

what are 5 functions of carbohydrates
☁️ Answer ☁️
PROVIDES INSTANT ENERGY TO THE BODY:
This appears to be the primary function of carbohydrates in the body.
Carbohydrates which we consume as food in the form of starch (ex: potato, bread), sucrose (ex: sugar, fruits), etc. get digested in the body to release glucose.
RESERVE FOOD:
Carbohydrate is also stored as the reserve food in the body. This is a precautionary measure for the body to cope up in times of hunger.
CARBOHYDRATES FORM OTHER BIOMOLECULES:
Carbohydrates in excess are converted into other bio-molecules of physiological importance. They mostly get stored in the form of fats.
DETOXIFICATION OF THE BODY BY METABOLISM:
Many drugs and toxic wastes in the body are metabolized for easy excretion in the body.
SPARING PROTEIN
In a situation where there is not enough glucose to meet the body’s needs, glucose is made from amino acids. Because there is no storage molecule of amino acids, this process requires the destruction of proteins, primarily from muscle tissue. The presence of adequate glucose basically spares the breakdown of proteins from being used to make glucose needed by the body.

2. What is the relationship between air temperature and air pressure at the
equator?
Answer:
Temperature refers to how warm or cold air is, and the density of the air is how many molecules are packed into a certain space of air. Air pressure is influenced by temperature because, as the air is warmed, the molecules start moving around more, so they bump into each other more often and create more pressure.
the pressure patterns associated with global circulation patterns. On the equator areas, since air is heated and rises, a zone of lower pressure will result.
Explanation:
mark it as brainliest. thnku hope it is helpful.
Explanation:
at the equator the air is moist and hot and when air is hot it's density decreases and so does the pressure exerted by it. and also air that contains water vapour is less denser than the air containing no or less water vapour so air containing less water vapour exerts more pressure
Which function of the integumentary system is illustrated in the release of sweat? A. Absorption B. Protection C. Sensory Reception D. Regulation E. Secretion F. Both regulation and secretion
Answer:
F. Both regulation and secretion
Explanation:
Through sweat glands and superficial blood vessels, the skin is able to cool the body and regulate its internal temperature.
The eccrine sweat gland, which is controlled by the sympathetic nervous system, regulates body temperature. When internal temperature rises, the eccrine glands secrete water to the skin surface, where heat is removed by evaporation.

Ou just read an article on the Endosymbiotic Theory. Based on what you read, what is the importance of the Endosymbiotic Theory?
Answer: The endosymbiotic theory suggests that eukaryotic organisms evolve from primitive prokaryotic organisms.
Explanation:
According to the endosymbiotic theory the organelles like mitochondria and chloroplast in the eukaryotic cells have arisen from aerobic bacteria. The aerobic bacteria being prokaryotic cell was consumed by the anaerobic bacteria or prokaryotic cell.
The following are the evidences of the origin of eukaryotic organisms from prokaryotic organisms:
1. The chloroplast and mitochondria have circular DNA like bacteria.
2. The mitochondria and chloroplast reproduce through binary fission which also occurs in bacteria.
Answer:
The Endosymbiotic Theory states that the mitochondrion and chloroplasts were consumed by a cell and now depend on one another to survive. Endosymbiotic Theory helps us by giving us the technology to use forensic sciences to solve cold cases.
