Mr. and Mrs. Green have a daughter, Georgia, who was born at Riverside Community Hospital. Mr. and Mrs. Blue have a daughter, Belle, who was born on the same date at the same hospital. Mrs. Green, having recently seen Belle, is convinced that Belle and Georgia had been assigned to the wrong parents at the hospital. Mrs. Green thinks that Belle is her biological daughter. ABO blood analysis was performed on all individuals involved:Mr. Green: Type AMrs. Green: Type A Georgia: Type AMr. Blue: Type ABMrs. Blue: Type ABelle: Type O
Is Mrs. Green correct? Is Belle her biological daughter? Explain.
Answers
Answer:
Yes, Mrs Green is correct that Belle is her biological daughter
Explanation:
According to this question, Mr. and Mrs. Green is said to have a daughter, Georgia while Mr. and Mrs. Blue is said to have a daughter, Belle. Both daughters were born the same day. Hence, a controversy occured as Mrs. Green thinks that Belle is her biological daughter.
Based on the blood analysis, the following were obtained:
Mr. Green: Type A
Mrs. Green: Type A
Georgia: Type A
Mr. Blue: Type AB
Mrs. Blue: Type A
Belle: Type O
The genotype of the following blood types is as follows:
Type A - iAiA or iAi
Type B - iBiB or iBi
Type O - ii
Type AB - iAiB
From the analysis of blood types of Mr and Mrs Green, which are both type A, they can possibly produce a child with type A.
However, from the analysis of Mr. and Mrs. Blue, it is impossible to have a child with blood type O. However it is possible for Mr and Mrs. Green if they are both heterozygous (iAi × iAi). The punnet square is attached. Hence, Mrs Green is correct about her claim since Mr. and Mrs. Blue cannot have a child with blood type A.

What characteristics of the blood cell helps it to pass freely through blood capillaries
Answers
Answer:
The cell is flexible and assumes a bell shape as it passes through extremely small blood vessels. It is covered with a membrane composed of lipids and proteins, lacks a nucleus, and contains hemoglobin—a red iron-rich protein that binds oxygen.
Answer:
The cell is flexible and takes the form of a bell through extremely small blood vessels. It is clothed in a fluid and protein-membrane, lacks a nucleus, and has hemoglobin—a rich red iron protein that binds oxygen.
Explanation:
The hemoglobin in red blood cells contains four iron-binding heme groups.
Heme groups of hemoglobin are binding on oxygen. Each molecule of hemoglobin can bind up to four molecules of oxygen.
Hemoglobin has a cooperative binding affinity to oxygen. The saturation of the molecule increases by oxygen. The connection of the initial molecule of oxygen affects the form of the other binding sites. For additional oxygen molecules, the binding becomes more favorable.
The four iron-binding hemo-groups are located in each hemoglobin molecule. Hemoglobin is known as oxygen-bound hemoglobin.
The reversible carbon dioxide is transformed into the carbonic acid reaction by the enzyme carbenoid anhydrase by the Red blood cells altering the blood PH.
Instead of being converted to carbonic acid, pH is controlled by carbon dioxide bindings to hemoglobin.
CO2: The enzyme found in RBCs catalyzing the reaction between carbonic anhydrase and carbonate dioxide and water.
Co-operative binding: When a first molecule is binding to a binding location, the same molecule is favored for the remainder of the binding locations by means of increased binding affinity.

global warming and climate change are impacting our Earth in different regions of the world.
Answers
Explanation: I'd first address the issue as a whole and explain the meaning and the general impacts of climate change, then use a variety of different places. For example, global warming causes the ice caps to melt in Antarctica. Then, explain how this has an impact on the environment meaning that polar bears could be in life-threatening situations and possibly even become extinct in the future which has a further impact on other animals in that food chain and ecosystem. This is just one example. You could also explain the unbearable heat in countries nearer the equator, which prevent crops from growing; the sea levels rising; or extreme weather events like huge flooding or heatwaves. It depends what you have learnt about in class, but I'm assuming it would be about this sort of thing.

Name & describe the six essential activities of the digestive tract.
Answers
Answer:
Ingestion: Consuming something orally, whether it be food, drink, medicine, or other substance; the first step of digestion. bolus: a round mass of something, especially of chewed food in the mouth or alimentary canal.
Propulsion: Propulsion means to push forward or drive an object forward. A propulsion system is a machine that produces thrust to push an object forward. On airplanes, thrust is usually generated through some application of Newton's third law of action and reaction.
Mechanical Digestion: Mechanical digestion is a purely physical process that does not change the chemical nature of the food. Instead, it makes the food smaller to increase both surface area and mobility. It includes mastication, or chewing, as well as tongue movements that help break food into smaller bits and mix food with saliva.
Chemical Digestion: Chemical digestion involves the secretions of enzymes throughout your digestive tract. These enzymes break the chemical bonds that hold food particles together. This allows food to be broken down into small, digestible parts.
Absorption: Absorption is a condition in which something takes in another substance. The process of absorption means that a substance captures and transforms energy. The absorbent distributes the material it captures throughout whole and adsorbent only distributes it through the surface.
Defecation: Defecation is the term given for the act of expelling feces from the digestive tract via the anus.

what is the part of endoplasmic reticulum without proteins attached?
Answers
Answer:
Regions of ER that lack bound ribosomes are called smooth endoplasmic reticulum, or smooth ER.
Answer:
The ER regions lacking bonded ribosomes are referred to as the smooth or smooth endoplasmic reticulum.
Explanation:
The Endoplasmic reticulum is a membrane network within the cell that transmits proteins and other molecules. Proteins called ribosomes are assembled at organelles. The ribosomes that are assembled to the endoplasmic reticulum give it a rough look when proteins are intended for cell membrane or export from the cells. Smooth endoplasmic ribosomes are absent and help to synthesize and concentrate various cell-required substances.
Either a smooth or rough endoplasmic reticulum is capable of producing protein in general for the rest of the cell to function. The raw endoplasmic reticulum contains ribosomes, small, red organelles that make these proteins. Sometimes the proteins remain inside the endoplasmic reticulum when made incorrectly.
It is retained and the endoplasmic reticulum is engulfed because it appears to be stuck in a way that does not lead the protein where it is supposed to go. There is also the smooth endoplasmic reticulum on which these ribosomes are not contained. This smooth endoplasmic reticulum produces other materials that the cell needs. The endoplasmic reticulum is an organelle that actually produces proteins and substances that are necessary for the rest of the cell.

Because of their capacity for rapid growth and reproduction, or because their new environments are devoid of any native predators or pests, invasive species frequently thrive in their new ecosystems. Thus, option B is correct.
What is a characteristic of invasive species?An invasive species doesn't develop slowly; on the contrary, they accelerate their growth because they are superior to all other species and have taken over the area completely.
Because of this, invading species may pose a threat to native species and interfere with crucial ecosystem processes.
A species must be easily adaptable for it to be invasive. It needs to multiply swiftly. It must result in harm to local property, the local economy, or the local fauna and flora. Accidental introduction of invasive species into a new area is common.
They are so successful because they can adapt and aren't intrusive. Because they have no competition, they are thriving while not being threatened.
