Answer:
1 black : 1 orange
Explanation:
This is a typical monohybrid cross involving a single gene coding for eye color in MendAlien. The allele for black eyes (B) is dominant over the allele for orange eyes (b). In an heterozygous state, Bb i.e. combination of both dominant (B) and recessive (b) alleles, the MendAlien will be phenotypically black.
In a cross between a heterozygous MendAlien (Bb) and an orange-eyed MendAlien (bb), two of the offsprings will have a Bb genotype and be phenotypically black-eyed which the other two will have a bb genotype and be phenotypically orange-eyed. Thus, a phenotypic ratio of 2 Bb : 2 bb will be obtained.
This is also equal to 1:1 i.e. 1 black-eyed : 1 orange-eyed.
Answer:
It increases haemoglobin's affinity.
Explanation:
When CO binds to one heme molecule, the haemoglobin molecule becomes in a relaxed state and oxygen can bind so very easily.
The problem is not in the uptake of oxygen, it's with its delivery. The affinity for oxygen increases so much such that it becomes impossible to release and deliver the oxygen to tissues.
Answer:
1.Observation and description of a phenomenon. The observations are made visually or with the aid of scientific equipment.
2.Formulation of a hypothesis to explain the phenomenon in the form of a causal mechanism or a mathematical relation.
3.Test the hypothesis by analyzing the results of observations or by predicting and observing the existence of new phenomena that follow from the hypothesis. If experiments do not confirm the hypothesis, the hypothesis must be rejected or modified (Go back to Step 2).
4.Establish a theory based on repeated verification of the results.
Explanation:
Answer:
Smooth muscle is found in the walls of hollow organs like your intestines and stomach. They work automatically without you being aware of them. Smooth muscles are involved in many 'housekeeping' functions of the body. The muscular walls of your intestines contract to push food through your body.
