Answer:
There is no punnet square attached but generally none of the offsprings from this cross will be homozygous dominant. The answer is 0.
Explanation:
The question illustrates a single trait encoded by a single gene. According to Mendel, a gene comes in two alternative forms called ALLELES. Each allele encodes different characters of the same gene. For example, let's use the trait for height encoded by a certain gene that has alleles T for tallness and t for shortness. T is dominant over t, meaning that T (tallness) will always mask the phenotypic expression of t (shortness) in a heterozygous state.
A heterozygous parent contains different alleles of the same gene i.e. Tt in this case. However, due to the dominance of allele T (tallness) over allele t (shortness), the tall trait will be expressed. On the other hand, a homozygous recessive parent contains the same alleles for the recessive trait i.e. tt
Using a punnet square, a cross between a heterozygous (Tt) parent and a homozygous recessive parent (tt) will produce offsprings with genotypes: Tt and tt in a 1:1 proportion.
Tt is heterozygous dominant
tt is homozygous recessive
None of the offsprings are homozygous dominant (TT), hence, the probability of producing a homozygous dominant offspring is 0.
t t
T Tt Tt
t tt tt
In humans, the maintenance of a stable internal temperature is a direct result of Homeostasis. Homeostasis is the ability of the body to maintain an equilibrium condition within it's internal environment even when dealing external changes. Homeostasis happens in human when there is an effort exerts by the body to regulate it's internal temperature around 98.6 degrees Fahrenheit. For example, during summer days we produce sweat for our body to cool off, and during winter we shiver for our body to produce heat.
Answer:
a. series of chemical reactions necessary for the use of the raw material.
Explanation:
The term metabolism is used to describe the various chemical reactions in the body that meet the structural and energy needs of a living being. Among the purposes of these chemical reactions, we can mention the synthesis and breakdown of biomolecules, energy production and the conversion of nutrient molecules into macromolecule precursor units.
Metabolism is not unique to humans and occurs in all living beings, whether unicellular or multicellular. The reactions that make up metabolism can be classified into two major metabolic processes: anabolism and catabolism.
D. HEARING is the sense most closely related to balance.
We maintain our balance through the detection of the movement of the fluid in our inner ear by hair cells.
Our inner ear has three semi-circular canals that are full of movable fluid and sensory hairs that are moved when the fluid moves. <span>These tell you which way your head and body is tilted in relation to gravity and give you information about movements and acceleration. Thy are also incidentally partially responsible for sea-sickness when the brain is fed conflicting information about the world from your ears and your eyes, the reason why you should get off your bed and go on deck to look at the horizon so the information matches.</span>
negative impact for social is that some people tend to be self-consious when out in the public. for physicsl and emotional it is alright but they need to be carfeul when going outdie and ake sure they are hanging out with the right people
