the disease erythroblastosis fetalis (also called hemolytic disease of the newborn) develops in a fetus or a newborn infant with Rh-positive blood and an Rh-negative mother. Symptoms results when maternal anti-Rh antibodies cross the placenta and interact with the fetus' erythrocytes. Why are the children of Rh-positive mothers not ay risk for this disease
Answer:
Explanation:
Hemolytic Disease of the newborn (HDN, Erythroblastosis Fetalis) is a blood disorder occurring at or around birth, where the blood groups of the mother and baby are not compatible. It occurs when the antibodies from a Rhesus negative (Rh-negative) mother, who has been sensitized from previous pregnancies or other means (transfusion etc), gives birth to an Rh-positive baby, and the blood of the mother and the baby eventually mixes. This causes the anti-Rhesus antibodies in the mother's blood to attack the Rhesus antigen (Also Called Anti-D antigen) on the baby's red blood cells, causing hemolysis that leads to several unpleasant symptoms.
Children of Rh-positive mothers are not at risk of developing HDN, because the mother does not produce anti-Rh antibodies since she is positive, hence there will be no antibodies to cross the placenta and react with the baby's rhesus antigens for Rh-positive babies.

What is the appropriate protein portion for men?
A. 2 palm portions
B. 3 palm portions
C. 2 cupped handfuls
D. 3 cupped handfuls
Answer:
A is correct- 2 palm portions is an appropriate protein portion for men
Explanation:
Two palm portions is the appropriate protein portion needed for men. It is advised to consume 0.8 grams of fat per kilogram of body weight. So, option A is right.
Amino acids are the building blocks of proteins. Your body requires amino acids to create hormones and enzymes, as well as to build and repair muscles and bones. They can also be utilized as a source of energy.
For a typical sedentary adult, the suggested dietary allowance is 0.8 grams per kilogram of body weight.
For men, 2 palm sized portions of protein is recommended in each meal. Palm is used to measure protein and handfuls is used to measure carbohydrates.
30 grams of protein are contained in one palm serving. Two palm pieces would therefore provide roughly 60 grams of protein for a man having 50-70 kilogram, which is a sufficient quantity for most guys.
Therefore, option A, 2 palm portions of protein is the appropriate protein portion for men is the correct answer.

One hot afternoon you are
standing on a beach and
notice the wind blowing in your
face as you look out to the
ocean. Why is this happening?
I NEED HELP ASAP!!!!
Answer:
The ocean breeze is causing a breeze coming toward the land from the sea towards the land. this is in all likelihood happening in light of the fact that as cooler air sinks back to the surface, it is blown towards the land and is warmed by Earth.
Sea breezes happen during summer days due to the inconsistent warming rates of land and water. During the day, the land surface warms up quicker than the water surface. Consequently, the air over the land is hotter than the air over the sea. Presently, review that hotter air is lighter than cooler air.

Which of the plant groups is the control group?
Answer:
plant group 1
Explanation:
Because, it is the only one that has not gotten fertilizer
The plant group that is the control group is plant group 1.
What are fertilizers?Any substance of earthy or man-made origin applied to soil or plant tissues to provide plant nutrients is referred to as fertilizers. It's possible to distinguish fertilizers from spreading agents.
The biology student is studying the effect of fertilizers on plants. Fertilizers increase the growth of the plant, and they also affect the soil of the plant in which they grow.
There are three groups of plants that are used. The growth of the first plant is O and 3.0. The growth of the second plant is 5, 3.2, 3, and 10 and the growth of the third plant is 10, 4.4, 20, and 5.0.
By seeing the Table, we can assume that the growth of plant group 1 is most affected and all other plants have similar.
Thus, the plant group is 1.

The blood-brain barrier (BBB) is most permeable to which of the following?
A. Platelets, white blood cells and red blood cells.
B. Sodium, potassium and chloride.
C. Glucose and oxygen.
D. Antibiotics.
Answer:
C. Glucose and oxygen.
Explanation:
The blood-brain barrier is a composition of endothelial cells that regulate the entry of substances into the extracellular fluid found in the central nervous system. Their high degree of selective permeability ensures that no solutes can cross the barrier, and only the right substances which are crucial to the workings of the central nervous system can scale through.
Oxygen which is needed for the proper functioning of the central nervous system and which is hydrophobic in nature is allowed to pass the blood-brain barrier. Glucose too which is an important nutrient/macromolecule for brain health can also move through the blood-brain barrier.
Why do people with diabetes have a hard time keeping a balance blood-glucose level? A)they don’t synthesize any insulin hormone, to help shuttle glucose into cells when there is a need. B)they don’t synthesize any hormone to keep their blood pressure in check
Answer:
A
Explanation:
i hope thia helps and sorry if yoy get it wrong! ^w^
People with diabetes have a hard time keeping a balance blood-glucose level because they don’t synthesize any insulin hormone, to help shuttle glucose into cells when there is a need. Thus, the correct option is A.
What is Diabetes?Diabetes may be defined as a type of metabolic disease that is characterized by elevated levels of blood glucose (or blood sugar).
The body of individuals with this type of chronic disease does not regulate the amount of glucose (a type of sugar) in the blood and the kidneys construct a large amount of urine.
This whole abnormal circumstance takes place when the body does not synthesize enough insulin hormone that helps in the regulation of elevated blood glucose levels by transforming it into other forms such as glycogen.
Therefore, people with diabetes have a hard time keeping a balance blood-glucose level because they don’t synthesize any insulin hormone, to help shuttle glucose into cells when there is a need. Thus, the correct option is A.

An ostrich and an emu are both flightless birds found on completely different continents (ostrich in Africa, emu in Australia). These birds have slightly different evolutionary histories, but have independently evolved similar adaptations due in part to the similar habitats they occupy. What type of evidence for evolution do these birds present
Answer:
The correct answer is "Biogeography".
Explanation:
The missing options for this question are:
-Comparative embryology
-Biogeography
-Bioinformatics
-Fossils
The correct answer is "Biogeography".
Biogeography is a field of study focused on how species have changed over its evolutionary history regarding its distribution and geographical localization. Biogeography particularly examines biological diversity patterns. The evidence of evolution between the ostrich and the emu populations is of biogeographical type, since they are located in different regions but they are exposed to similar habitats.
