Consider two children with the same two parents. Would you expect them to have the same sets of chromosomes? Explain why or why not.

Answers

Answer:

Some of the same

Explanation:

Well, if one is a boy and one is a girl they might look similar but they will have a lot more different  chromosomes than if they were both the same genders, but they still wouldn't be exactly the same because everyone, even identical twins have  chromosomes differences, even if you cant see them. My final reason is that one sibling might get more genes from one parent than the other.

What is an example of the strong force in action

Answers

Answer:

A magnet keeps a cabinet door closed. The Sun pulls on Earth as Earth moves around the Sun. The protons in the nucleus of a carbon atom are held together.So this is an example of the strong force in action.

There are 4 fundamental types of forces:

1. Electromagnetic

2. Gravitational

3. Strong

4. Weak

You asked about strong force, the strong force keeps quarks together in clusters to make more-familiar subatomic particles, such as protons and neutrons.

Which does not describe the relationship because nucleus and the electron cloud of an atom?

Answers

Complete Question:

Which does not describe the relationship between nucleus and the electron cloud of an atom?

Group of answer choices.

A. the electrons move faster than the particles in the nucleus

B. the masses of the nucleus and electron cloud are balanced

C.the charges of the nucleus and electron cloud are balanced

D.the electron cloud takes up much more space than the nucleus

Answer:

B. the masses of the nucleus and electron cloud are balanced

Explanation:

An atom can be defined as the smallest unit comprising of matter that forms all chemical elements. Thus, atoms are basically the building blocks of matters and as such determines or defines the structure of a chemical element.

Generally, atoms are typically made up of three distinct particles and these are protons, neutrons and electrons.

In Chemistry, electrons can be defined as subatomic particles that are negatively charged and as such has a magnitude of -1.

An electronic cloud can be defined as a group of negatively charged electrons circulating around an atomic nucleus. It is typically referred to as valence electrons.

Valence electrons can be defined as the number of electrons present in the outermost shell of an atom. Valence electrons are used to determine whether an atom or group of elements found in a periodic table can bond with others.

Both the protons and neutrons of an atom of a chemical element have a mass of 1 atomic mass unit (amu) while an electron have an approximate mass of 0 atomic mass unit (amu).

Hence, the masses of the nucleus and electron cloud of an atom cloud are not balanced.

During the Cardiovascular Function Labster simulation, cardiac output did not increase as much as oxygen consumption rate (which increased 8x), what is the most likely mechanism that could allow increased oxygen delivery by the cardiovascular system

Answers

Answer:

An increase in the rate of oxygen that has been removed from hemoglobin could increase the supply of oxygen by the cardiovascular system.

Explanation:

Hemoglobin is a protein, present in the cardiovascular system, whose main function is to remove oxygen from the lungs and take it to the tissues of the human body. Therefore, the more oxygen is removed from the hemoglobin, the greater the oxygen supply. This applies even in the situation presented in the question above, where cardiac output did not increase in the same way as oxygen consumption. In this case, if oxygen consumption is high, the removal of oxygen from the hemoglobin must be increased to supply this consumption.

give possible reasons for the poor performance of the monopolies​

Answers

Explanation:

goods can be restricted to keep prices high. This leads to underprovision, or scarcity

The main reason of the poor performance of the monopolies​ is it is more expensive than in competitive markets Monopolies face inelastic demand and can raise prices, leaving consumers with no choice.

What is monopoly?

A monopoly occurs when there is a solitary vendor on the market. The monopoly case is considered the polar opposite of perfect competition in conventional economic analysis.

The major issue facing the monopolist is, by definition, the industry demand curve, which is slightly negative.

The drawbacks are:

Expensive in comparison to competitive markets Monopolies can raise prices when demand is inelastic, leaving consumers with no choice.A reduction in consumer surplus.Monopolies have a lower likelihood of being efficient.Potential scale diseconomies

The other factors which are involved in the carbon and oxygen cycles are air, ground, respiration, and photosynthesis.

Which factor contributes to the carbon cycle?

Explanation: Human activities have a tremendous impact on the carbon cycle. Burning fossil fuels, changing land use, and using limestone to make concrete all transfer significant quantities of carbon into the atmosphere.

How do plants and animals interact with the carbon cycle differently from one another?

Through food chains, the carbon that is in plants moves to the animals that eat them. Animals that eat other animals get the carbon from their food too. Carbon moves from plants and animals to soils. When plants and animals die, their bodies, wood, and leaves decay bringing the carbon into the ground.

Cells used for absorption typically utilize ________to maximize surace area.
Nearly every human cell has a single ________whose function is not completely understood.
In humans only the male gametes posess a ________

Answers

Answer:

Microvilli; nonmotile primary cilium; flagellum

Explanation:

Microvilli are cellular membrane protrusions found in different organs/structures specialized for absorption (e.g., digestive tract, kidneys), which are involved in different cellular functions such as absorption, secretion and cellular adhesion. For example, microvilli on the surface of epithelial cells act to increase the surface area for absorption of food and nutrients. Moreover, flagella (singular: flagellum) and cilia (singular: cilium) are structures found in eukaryotic cells which are composed of proteins (microtubules) surrounded by a membrane. Flagella and cilia are generally involved in the locomotion of the cell. There are two types of cilia, motile cilia and non-motile (primary) cilia. Non-motile primary cilia are found on the surface of almost all mammalian cells. In humans, sperms can swim by using a long flagellum made up of microtubules, which is fundamental for the transport of male DNA to the egg cell.

Answer:

Microvilli; nonmotile primary cilium; flagellum

Explanation:

Cells used for absorption typically utilize Microvilli to maximize surace area.

Nearly every human cell has a single nonmotile primary cilium whose function is not completely understood.

Living organisms are commonly divided into six kingdoms: archaea, bacteria, fungi, protists,
plants, and animals. What’s the biggest problem with classifying organisms in this way?

Answers

they may be in the same category but they don't have the same biological makeup

The biggest problem in classifying organisms this way is that the way is not well-defined and diverse and if any organism doesn't fall into another kingdom that is added to these kingdoms.

What is classification?

Organisms are classified into groups and classes on the basis of their characters and structure. It helps in identifying and understanding the diversity of living organisms.

The six kingdom classification is based on similar characteristics like cell type, and food. Before this, scientists divide the organism into plants and animals.

Thus, The major issue with this system of classifying creatures is that it is not well-defined and diverse, and if an organism does not fit into one of the existing kingdoms, it is added to those already there.

What is deoxygenated blood?

"Deoxygenated blood refers to the blood that has a low oxygen saturation relative to blood leaving the lungs."

What is the function of deoxygenated blood?

"The deoxygenated blood returns from the body to the right atrium and from there enters the right ventricle that pumps it to the lungs through the main pulmonary artery. In the lungs, the blood refills its oxygen supply and gets rid of carbon dioxide."

What are the steps of the circulatory system?

The steps involved in blood flows through the heart in the following order:

The blood first enters the right atrium.The blood then flows through the tricuspid valve into the right ventricle.When the heart beats, the ventricle pushes blood through the pulmonic valve into the pulmonary artery.The pulmonary artery carries blood to the lungs where it “picks up” oxygen.
