In biological molecules, carbon,nitrogen, oxygen often form covalent bonds with hydrogen.Arrange these Bonds from most polar to least polar: C-H, N-H,O-H

Answers

Answer 1

Answer:

The order of polarity from most polar to least polar is as follows:

O-H > N-H > C-H

Explanation:

The polarity of a substance is a function of the charges of the ionic elements that makes up the substance. A bond between two ions is considered polar if it is between a negatively charged and positively charged ions. Hence, the stronger the charges of the ions in the bond, the more the polarity.

In this question, hydrogen is said to form covalent bonds with carbon, oxygen and nitrogen in biological molecules. However, the covalent bonds formed will not possess the same degree of polarity.

The bond between oxygen and hydrogen (O-H) is considered most polar amongst these three because OXYGEN atom is the most electronegative among the three ions. Hence, it will pull more electrons to itself and make the hydrogen ion more electropositive. This is followed by the bond between nitrogen and hydrogen (N-H) because nitrogen is more electronegative than carbon. The least polar is the bond between carbon and hydrogen as carbon is the least electronegative, hence, will not be able to pull electrons from hydrogen effectively.

The order from most polar to least polar is: O-H > N-H > C-H

true or false Geoengineering will have no negative effects on the environment.

Answers

The answer is false

It is false that geoengineering will have no negative effects on the environment.

What is geoengineering ?

Geoengineering, also known as Climate Engineering, is the deliberate, extensive modification of the Earth's environment and climate in order to stop further climate change, halt and stop global warming, and lessen the effects on human society and the ecosystem.

Spraying compounds into the atmosphere to create reflecting aerosols and reflect sunlight into space is known as solar geoengineering. Although this would prevent global temperatures from rising, local or regional temperatures may still rise over the coming years, according to a recent study.

Hence, it is false that geoengineering will have no negative effects on the environment.

Why do living things share fundamental characteristics

Answers

Answer:

All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing. When viewed together, these characteristics serve to define life.

Life processes are important to carry out daily life activities. They help to produce energy and maintain homeostasis in the body. The life processes help a body survive with the changes in the environment.

There are several fundamental characteristics or capacities that all living things share, including order, environmental sensitivity or responsiveness, reproduction, growth and development, regulation, homeostasis, and energy processing.

What fundamental characteristics share by living things?

All living things share certain basic characteristics or functions, such as order, sensitivity to their environment, growth and development, reproduction, regulation, homeostasis, and the ability to process energy.

These characteristics work to define what it means to live. These characteristics collectively contribute to the definition of life. All of these characteristics will be found in living things.

All living things share the capacities to procreate, grow and develop, use energy, maintain homeostasis, respond to their environment, and be adaptable.

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.

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

Answers

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.

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

A

Explanation:

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.

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.
