Blood type is an example of ✔ codominance
Explanation:
Blood type is determined by the ✔ antigens on the blood cells.
✔ Antibodies attack foreign blood that does not contain the same antigens.
Blood type is an illustration of codominance.
What is blood type?Blood group also known as blood type refers to classification of blood on the basis of the absence and presence of antibodies and inherited antigenic components on the red blood cells surface. These antigens may be:
ProteinsCarbohydratesGlycolipidsGlycoproteinsThe blood type in humans is an example of codominance. In codominance, neither of the allele can inhibit the expression of the other allele. One of the example is the ABO blood group in humans. In this, both the alleles A and B are expressed.
Therefore, if a person is inheriting allele A from the mother and allele B from the father, he or she will have the blood type AB.
Thus, blood type is an example of codominance.

Whats sounds can dogs hear that we cant ?
Answer/Explanation:
Dogs have outstanding senses. not only do they have good smelling sense but they also have a good sense of hearing. Humans can't hear hear above 20,000 HZ. However, dogs can hear much higher pitches than we can. Dogs can hear up to 65,000 HZ. This is why we are unable to hear a dogs whistle, but the dogs can.

Answer:
In facilitated diffusion, molecules move down their concentration gradient.Explanation:
In facilitated diffusion, substances move into or out of cells down their concentration gradient through protein channels in the cell membrane. Simple diffusion and facilitated diffusion are similar in that both involve movement down the concentration gradient.
Osmosis refers specifically to the movement of water across a semipermeable membrane, with the solvent (water, for example) moving from an area of low solute (dissolved material) concentration to an area of high solute concentration.
Active transport is the movement of dissolved molecules into or out of a cell through the cell membrane, from a region of lower concentration to a region of higher concentration. The particles move against the concentration gradient , using energy released during respiration .

DNA polymerase is an enzyme required in DNA replication. Its role is to synthesize DNA, adding individual nucleotides to each strand of newly synthesized DNA with the help of other enzymes such as primase and ligase. There are several families of DNA polymerase in both prokaryotes and eukaryotes, but through different species, portions of DNA polymerase are highly conserved. What do you think is the evolutionary significance of DNA polymerase? What do you think would happen if there was a genetic mutation on the genes encoding for DNA polymerase?
A sample answer would look like this: The DNA polymerase has evolutionary significance because it is required for DNA to be transmitted across generations. A genetic mutation in a gene encoding for DNA polymerase could lead to significant flaws in DNA replication, which could lead to major flaws in the DNA replicated for cell division. This could lead to large-scale errors and result in the death of the organism.
Answer:
Abstract. DNA polymerase I (pol I) processes RNA primers during lagging-strand synthesis and fills small gaps during DNA repair reactions. However, it is unclear how pol I and pol III work together during replication and repair or how extensive pol I processing of Okazaki fragments is in vivo

Cross two heterozygous black mice and tell the possible phenotypes and
genotypes in their offspring.
Answer:
Phenotype: 3 black mice: 1 brown mice
Genotype: 1 BB: 2Bb: 1bb
Explanation:
This question involves a single gene coding for fur color in mice. The allele for black color (B) is dominant over the allele for brown mice (b). This means that a mouse that is heterozygous will be black.
If two heterozygous black parents are crossed i.e Bb × Bb, the gametes produced by each parent are: B and b. Using these gametes in a punnet square (see attached image), the following offsprings will be produced:
BB, Bb, Bb, and bb
- The phenotypes of this cross is 3 black mice: 1 brown mice
- The genotypes of the cross is 1 BB: 2Bb: 1bb

draw neat and labelled diagram of smooth muscle?
Muscular system is an organ system, Body performs all the kind of movements with the help of muscular system. Almost all the animals have muscles. The muscular system is composed of specialized cells called muscle fibers. Their predominant function is contractibility. Muscles are attached to bones or internal organs and blood vessels. There are more than 600 muscles present in a human body.
[tex]\Large\textbf{Types of Muscles:}[/tex]
There are three types of muscles in a vertebrate body. They are
skeletal musclescardiac musclessmooth muscles[tex]\Huge\text{Smooth Muscles}[/tex]
Smooth muscles are structurally the simplest of all muscles types. They are non-striated, and consist of long spindle shaped uni-nucleated muscle cells that are usually arranged in sheets that surround the body's hollow organs. Smooth muscles are also involuntary in action. Smooth muscles push the food through the digestive tract, they empty your urinary bladder, they control the diameter of the blood vessels, the diameter of your eye, the state of erection of hair of the skin, and the smooth muscles form the layer of sheet around all the visceral organs.
Non-striated muscles, this means that muscles do not have transverse light and dark bands. The striations are caused by the regular arrangement of contractile proteins (actin and myosin). Actin is a globular contractile protein that interacts with myosin for muscle contraction. This means that non-striated muscles can not contract, thus they can not move.
Uni-nucleated Muscles, Smooth muscles are the only muscles which have cells with only one nuclei.
Involuntary in action, This means that their contraction is not under the control of somatic nervous system. The involuntary muscles are automatically controlled by the autonomic nervous system controls the activities of the inner visceral organs (heart, glands, smooth muscles), while the somatic nervous system controls all the voluntary actions.
Visceral Organs, word Visceral arises from latin word Viscera which means "the organ of the body", So Visceral organs are all the internal organs of the body, specifically those within the chest and abdomen. They are covered with visceral membrane made of smooth muscles.
I have attached two pictures of the smooth muscles, one is colored and the other one is colored and the other one is diagrammatic.

After radiation exposure, a cell that cannot divide will most likely stay in which phase?
Answer:
G0 phase
Explanation:
IF the cell doesn't receive a signal to divide, then it will go into a stage called the G0 phase. Most cells are in this stage until they receive a signal to divide, and then continue the cell cycle.
Reflex action
(a)
Miriam accidently touches a hot pot and quickly withdraw her hand. Describe
the series of events in the nervous system which causes Miriam to react thi
way
Answer:
Reflex action/reflex arc/reflex (allow "involuntary") The stimulus (heat) is detected by temperature receptors in the skin. This causes impulses to travel along a sensory neurone to the spinal cord, due to chemical changes across the synapses. Here they go along a relay neurone, and then are sent via a motor neurone to the effector (an arm muscle in this case). The muscle contracts, moving the hand away and preventing further harm.
Which of these changes to fuel consumption would lessen human
impacts on global climate?
Select one:
A) Decreasing research of all wind or water-based electricity generation technologies
B) Switching from coal to natural gas or nuclear energy to generate electricity
C) Increasing electricity production from coal
D) Banning any form of carbon emissions trading programs
Switching from coal to natural gas or nuclear energy to generate electricity will lessen human impacts on the global climate.
What is climate change?It is the changes to climate brought about by anthropological emission of greenhouse gases.
Greenhouse gases are emitted from human actions such as the burning of coal, removal and burning of forest layers, etc.
Thus, in order to lower human impacts on climate, replacing activities such as the burning of coal with clean technology such as nuclear energy to generate electricity would go a long way.
