This pair may have 1/8 type O with N antigens kids, which is a proportion of different phenotypes.
The man's genotype is I⁰I⁰ and the woman's genotype is IᵃI⁰ because the man has type O blood and the woman has children with him. Their offspring's genotypes will be as follows:
F/M I⁰ I⁰
Iᵃ IᵃI⁰ IᵃI⁰
I⁰ I⁰I⁰ I⁰I⁰
Children with O group blood have a 0.5 chance of being born, and children with A group blood have a 0.5 chance. The MN antigen is heterozygous for both people. Following are the odds of inheriting MN antigens:
F/M M N
M MM MN
N MN NN
0.25 percent of people have the homozygous M antigen type.
The likelihood of having the MN antigen type is 0.5.
0.25 percent of people have homozygous N antigen types.
As these two events are independent of one another, the chance of ABO blood group and MN antigen inheritance is the product of their individual probabilities.
Type A with M antigen is equal to 0.5 x 0.25 x 0.125 x 1/8.
Antigens M and N in Type A = 0.5 x 0.5 x 0.25 x 1.4
N antigen type A = 0.5 x 0.25 x 0.125 x 1/8
Type O antigen M = 0.5 0.25 0.125 1/8
Type O antigens M and N = 0.25 = 1/4
0.125 = 1/8 for type O with N antigens.
In the event that both parents are heterozygous for the gene (Hh) in charge of the synthesis of the H substance, then

intervertebral discs comprised of fibrocartilage are found within what type of joints? multiple choice question. symphyses syndesmoses synchondroses sutures
Intervertebral discs comprised of fibrocartilage can be found at the symphyses.
Intervertebral discs are discs made of cartilage that function to prevent spinal structures from rubbing against each other and serve as cushions for the spine. Cartilage which is made of dense, clear, bluish-white and very strong material has two types of joints, one of which is the symphysis joint where the bones are connected by flat fibrocartilage discs which remain unhardened throughout life., for example, the intervertebral disc and pubic symphysis which join the pub part of the right and left vertebrae. For this reason, the symphysis joint is often referred to as a fibrocartilaginous joint.

a(n) is a neuron that carries infromation from the external environment or from the body, back to the central nervous system
A sensory neuron is a neuron that carries information from the external environment or from the body, back to the central nervous system.
When you contact a hot surface with your fingertips, your sensory neurons will fire and transmit messages to the rest of your nervous system about the information they have just received. Sensory neurons are the nerve cells that are activated by sensory input from the environment. The brain obtains information from sensory neurons thus allowing us to sense, touch, see, smell. The brain interprets the information and sends the instruction back to the muscled using motor neurons and thus allowing us to act accordingly.

two competing theories about the source of oxygen in photosynthesis were tested in the 1940s-50s using radioactive isotopes. about what did the theories disagree?
Theories that were obtained while doing research using radioactive isotopes disagree as to whether the [tex]O_{2}[/tex] produced during photosynthesis came from [tex]CO_{2}[/tex] (carbon dioxide) or [tex]H_{2}O[/tex] (water).
Most scientists believed that plants produced [tex]O_{2}[/tex] by removing it from [tex]CO_{2}[/tex] in the 1800s. In the 1950s, researchers tested this theory by tracking the fate of oxygen atoms during photosynthesis using the heavy oxygen isotope [tex]^{18}O[/tex].
There was two experiments:
1. A plant exposed to [tex]^{18}O[/tex]-containing carbon dioxide produced no labeled oxygen gas ([tex]^{18}O[/tex] containing).
2. A plant given [tex]^{18}O[/tex] water produced tagged [tex]O_{2}[/tex].
These investigations demonstrated that the [tex]O_{2}[/tex] produced during photosynthesis is derived from [tex]H_{2}O[/tex] rather than [tex]CO_{2}[/tex].

what would be the effect of swapping the dna-binding domain of a eukaryotic activator with a different dna-binding domain? multiple choice question.
The activator's ability to activate a target promoter is unaffected by the replacement of the DNA binding domain, which just changes the site at which it will function.
An activator protein binds to something, but what happens after it binds?The DNA regulatory sites close to the promoter regions, which function as on/off switches, are where activator proteins interact. This binding promotes the activity of the RNA polymerase and the transcription of adjacent genes.
How do activator proteins function in eukaryotic cells?Gene expression in a eukaryotic cell must be activated by transcriptional activators. RNA polymerase II can be drawn to the promoter or extended with the help of activators attached to the enhancer.

in which form of reproduction does the offspring grow specifically from the stem or root of a plant? (1 point) responses
In asexual type of reproduction the offspring grow specifically from the stem or root of a plant.
New plants are created by asexual reproduction without the need for seed production. In this kind of asexual reproduction, the roots, stems, leaves, and buds are used to create new plants.
Asexual reproduction refers to a type of reproduction when a offspring is born to a single parent. The newly created people are clones of their parents since they have the same genetic makeup and physical characteristics. Both multicellular and unicellular organisms can reproduce asexually.

This outer covering is formed during a process called budding off and the outer covering comes from the infected host cell. Newly created virus cells get enveloped in an outer coat, made of small piece of plasma membrane of cell during the budding process.
