If Tom Harris had type AB blood and Mary had type O, could the type O child they brought home be their child? * No, the baby would have to have inherited a gene for O from both parents and Tom has only a gene for A or B. Yes, both parents had the recessive hidden gene for O blood in their genotype which they passed on to the baby. No; the baby would have to have Type AB blood that it inherited from the father since A and B are dominate to O. Yes; the baby inherited type O blood from the mother Mary Harris which is dominant to the genes for both A and B.
The study of blood is called hematology. The component of blood is RBC, WBC, platelets, and plasma.
The correct answer to the question is option B.
What is a blood group?
A blood type is a classification of blood, based on the presence and absence of antibodies and inherited antigenic substances on the surface of red blood cells.
These antigens may be proteins, carbohydrates, glycoproteins, or glycolipids, depending on the blood group system.
The genes A and B are dominant over O therefore the O blood group can not be seen in offspring.
Hence, the correct answer to the question is option B is Yes, both parents had the recessive hidden gene for O blood in their genotype which they passed on to the baby. No; the baby would have to have Type AB blood that it inherited from the father since A and B are dominant to O.

An individual’s mother has blond hair and blue eyes. That individual’s father has brown hair and brown eyes. The individual, however, has brown hair and blue eyes. How did that individual inherit a "mixture" of traits rather than either maternal (blonde hair and blue eyes) OR paternal (brown hair and brown eyes) traits?·maternal and paternal chromosomes sort independently·maternal chromosomes and paternal chromosomes remain together·one of the gametes was missing a chromosome
maternal and paternal chromosomes sort independently
Alleles for a gene are present on a particular locus on homologous chromosomes. Meiosis includes the pairing of homologous chromosomes and their segregation of opposite poles. One member of a homologous pair is paternal and the other is inherited from mother.
The random arrangement of homologous chromosomes at the equator of the cell during metaphase I result in independent segregation of paternal and maternal chromosomes to opposite poles during anaphase I. This leads to new combinations of traits in the progeny which were otherwise not present in either parent.
As your group adds to the graphic, your teacher tells you to add an example for each of the four boxes at the base. Which example would BEST fit under the first box: Physical Barrier?A) resistance chicken pox either from exposure or vaccine B) the enzyme lysozyme present in your tears degrades bacteria C) white blood cells rush to the site of a wound to engulf bacteria D) exposure to antigens lead to the production of antibodies that mark cells for destruction
Answer: The correct answer is B) the enzyme lysozyme present in your tears degrades bacteria.
Tears are the part of innate immunity, which is one of the two types of immune system ( innate and adaptive).
Innate immunity ( also called first line of defense) can be described as the generalized defense strategy of individual ( that is present from birth).
It includes certain physical and chemical barriers that are always ready to fight and clear pathogen.
For example- Lysozyme ( found in tears, saliva, mucus, and breast milk) degrade bacteria by breaking their cell wall and thus prevent infection.
Thus, option B) is the right answer.
Archaea differ from bacteria in that archaea
Archaea have more complex RNA polymerases than Bacteria, similar to Eucarya. Unlike bacteria, archaea cell walls do not contain peptidoglycan. Archaea have different membrane lipid bonding from bacteria and eukarya. There are genetic differences.
Do most people want to have a low infant mortality rate or high infant mortality rate?
definitely low infant mortality rate
Retinol, cholecalciferol, tocopherol, and phylloquinone are all names of what? water-soluble vitamins fat-soluble vitamins antioxidants
The correct answer is fat-soluble vitamins.
The fat-soluble vitamins are soluble in lipids and usually absorbed as fat globules (chylomicrons). They are absorbed via the lymphatic system of the small intestines and then transported into the blood circulation within the body.
Vitamin A (retinol) has an important role in maintaining healthy vision.
Vitamin D (cholecalciferol) is important for bone health and development and it is produced naturally in the human body when the skin is exposed to the sun.
Vitamin E (tocopherol) is an antioxidant that can help the body destroy free radicals.
Vitamin K (phylloquinone) has a role in forming the blood clots.
In humans, one function of the skin is to prevent water loss. Skin releases water or holds in water when necessary.Which two structures in plants have a similar function to skin?
> roots and chloroplasts
> phloem and roots
> cuticle and stomata
> stomata and phloem
Cuticle and stomata in plants have a similar function to skin.
What are the functions of cuticles?
The cuticle is well known for its functions as a diffusion barrier limiting water and solute transport across the apoplast and for its protection of the plant against chemical and mechanical damage, as well as pest and pathogen attack.
In some higher plants, the cuticle is a water-impervious protective layer covering the epidermal cells of leaves and other parts and limiting water loss. It consists of cutin, a waxy, water-repellent substance allied to suberin, which is found in the cell walls of corky tissue.
The cuticle itself comprises three layers: the cuticular layer; cuticle proper; and epicuticular waxes. The cuticular layer is the innermost layer, which overlays the primary wall and consists of cellulose and other polysaccharides along with cutin and wax.
