A woman with type AB blood has children with a man who has type o blood. What are the chances they will have a child with type o blood?
25%
0%
100%
50%

Answers

Answer 1

Answer:

The chance of a woman with an AB blood type and a man with an O blood type having a child with O blood is 0%.

Explanation:

A mother with blood type AB (AB) will pass either antigen A or antigen B to the offspring, while the father with blood type O (OO) will not pass any antigen.

The result of an AB X OO cross would be

Alleles        O        O

A                AO     AO

B                BO     BO

For this reason, the offspring of this couple will be

Blood type A (AO) 50%. Blood type B (BO) 50%. Blood type O (OO) none.

Heredity of blood type depends on the presence of surface antigens on the erythrocyte membrane. Blood type O occurs in persons whose red blood cells do not possess surface antigens A or B.

Surface antigens are what determine blood type, so :

The presence of antigen A determines blood type A. Blood type B depends on the presence of antigen B. Blood type AB has both antigens.

Blood type O has no antigens, and for blood type O to manifest, it must have both alleles for O.

A mother AB and father O cannot have offspring with blood type O.

Removing a specific group of trees within a small area over a long period of time is
a. clearcutting
b. seed tree cutting
C. group selection
d. single tree selection

Answers

Answer:

C. group

Explanation:

Removing a specific group of trees within a small area over a long period of time is group selection. The correct option is C.

What is group selection?

A quantitative definition of group selection is when the average group fitness is greater or less than the mean of the fitness values of the individual members.

Another definition of group selection is when features evolve in accordance with the fitness (survival and reproductive success) of groups.

The conclusion was that although group selection is theoretically feasible, in practice it almost always favors one group over another.

Group selection is the long-term removal of a certain group of trees in a constrained region. In a clearcut, all the trees in a specific region are taken out at once.

The removal of shelterwood cutting clears an area's also clears land cleared for shelterwood cutting, which also involves cutting downing shelterwood cutting, but it is a completes a method of clearing

Thus, the correct option is C.

Body cells divide by meiosis for the growth and repair of cells, while sex cells divide by mitosis for sexual reproduction.


Body cells divide by meiosis for sexual reproduction, while sex cells divide by mitosis for the growth and repair of cells.

Answers

Answer:

The difference that the scientist would expect to see between body cells and sex cells with respect to cell division is that body cells divide by mitosis for the growth and repair of cells, while sex cells divide by meiosis for sexual reproduction.

Explanation:

The behavior of the different cell types with respect to their division depends on the functions that each type has.

Somatic cells are those that define the structure and function of the organism, forming tissues by binding together. The process of mitotic division —to obtain from an original cell two identical daughter cells— is important for the growth, development and repair of an individual's tissues.Sex cells or gametes have half of the chromosomal charge —they divide by meiosis, a reductive cell division— and are involved in the process of sexual reproduction.

    The characteristics described for each cell type explain why the other options are not correct.

Body cells divide by mitosis for the growth and repair of cells, while sex cells divide by meiosis for sexual reproduction.

I WILL GIVE BRAINLIEST Pretend you're riding the bus to school on a very cold and snowy day. List 3 different phases changes you might see along the way.

Answers

If you’re talking about scientific phases you will see
1. precipitation(the snow falling)
2. evaporation(water turning into vapor)
3.melting(snow turning the water)

While riding the bus to school on a very cold and snowy day three different phases changes you might see along the way are mentioned below:

1. precipitation(the snow falling)

2. evaporation(water turning into vapor)

3. melting(snow turning the water)

What is precipitation, evaporation, and melting?

Evaporation is the process in which liquid changes in vapour or gas and it can be easily observed during hot summer days when there is raining and when wet clothes dry in the presence of sunlight. Evaporation is directly proportional to temperature and when rate of evaporation increases the temperature also increases.

Precipitation is the water that is falling from the sky and it occurs when a portion of atmosphere becomes saturated with water vapour.

Melting is the process in which solid is converted into liquid like ice cube converted into liquid water and this is one of the example of melting.

Therefore, the mentioned below are three phases changes :

1. precipitation(the snow falling)

2. evaporation(water turning into vapor)

3. melting(snow turning the water)

conditional response=getting hungry before lunch time

habit=brushing your hair

reflex=eye blinking

I hope this helped and was explained better

The behavior type of response with the corresponding action is instinct-migration, trial and error-putting a puzzle together, conditional response-getting hungry before lunchtime, habit-brushing your hair, and reflex-eye blinking.

What is the corresponding action?

The brain control action is regulated by the body some are involuntary and others are voluntary it creates a rhythm in our body to make the system regulate.

Migration is instinct but putting puzzle is a trial and error condition, when the eye is blinked is a reflex action, and crushing your hair is a habit while getting hungry before lunchtime is a conditional response.

All the action of the body is controlled by the body's action some signals are sent to the body to regulate every action to control conditional response or habit.

Therefore instinct-migration, trial and error-putting a puzzle together, conditional response-getting hungry before lunchtime, habit-brushing your hair, and reflex-eye blinking.
