Answers

Answer 1

Answer:

1, 2, & 3

Explanation:

The cell membrane controls what enters and exits the cell and thus protects the cell.

Water molecules and ions move through channel proteins. Other ions or molecules are also carried across the cell membrane by carrier proteins.

Cell membranes surround all animal, plant, and bacterial cells.

In humans type A blood is caused by the antigen A in the red cells resulting from gene A. Type B is caused by a gene B for antigen B. Type O blood results from the absence of either gene while the presence of both genes causes both antigens to be formed resulting in type AB blood. If a person of blood group AB marries one belonging to blood group O what will be the blood groups of their children? Show the Punnett square for this cross.

Answers

Answer:

Type A and type B

Explanation:

This question is describing blood type in humans. According to the question, type A blood is caused by the antigen A of gene A while Type B is caused by a gene B for antigen B. Type O blood results from the absence of either gene while the presence of both genes causes both antigens to be formed resulting in type AB blood.

If a person of blood group AB i.e. genotype (iAiB) marries one belonging to blood group O (genotype ii), the following genotypes of offsprings will be produced (see attached image for punnet square):

iAi - blood type A

IBi - blood type B

which statement best describe the relationship between the products of photosynthesis and the reactants in cellars respiration

Answers

Answer:

Photosynthesis products serve as a chemical energy suppliers for reactants and cellular respiration.

Since photosynthesis creates oxygen and oxygen needed for cellular respiration in the production of carbon dioxide and energy, carbon dioxide is used to generate plant energy and oxygen.

Explanation:

Photosynthesis products produce chemical energy by reacting to cellular respiration. Photosynthesis products interact to extract ATP from cells in cellular breathing reactants.

Photosynthesis products inhibit the reactants in the presence of light in cellular breathing.

A component of a circuit changes, as shown below. How would this change affect the electric circuit? A switch is closed, so the circuit would be incomplete and broken and the lights in the circuit would not shine. A switch is closed, so the circuit would be complete and unbroken and the lights in the circuit would shine. A switch is opened, so the circuit would be incomplete and broken and the lights in the circuit would not shine. A switch is opened, so the circuit would be complete and unbroken and the lights in the circuit would shine. Mark this and return Save and Exit

Answers

Answer:

A switch is closed, so the circuit would be complete and unbroken and the lights in the circuit would shine.

Explanation:

The image shows an open switch to a closed switch.

A closed switch represents a complete circuit, and an open switch represents an incomplete circuit. The lights would shine and the circuit would be complete because the switch is now closed.

The change affects the electric circuit as A switch is closed, so the circuit would be complete and unbroken and the lights in the circuit would shine. The correct option is B.

What is an electric circuit?

When an electric charge builds up inside of an object, it disperses across its surface and stays there until it can be discharged by an electrical current or electrical discharge; this is known as "static electricity."

From an open switch to a closed switch is shown in the image. An incomplete circuit is represented by an open switch, and a complete circuit is by a closed switch. The switch is now closed, so the lights would turn on and the circuit would be complete.

Therefore, the correct option is B. A switch is closed, so the circuit would be complete and unbroken and the lights in the circuit would shine.

An autotroph is what?

An organism that can manufacture food by utilizing light, water, carbon dioxide, or other chemicals is known as an autotroph. Autotrophs are occasionally referred to as producers since they grow their nourishment. Although the most well-known autotroph is a plant, there are numerous more types of autotrophic creatures.

What exactly are heterotrophs and autotrophs?

Autotrophs are referred to as producers since they can generate their food using energy and raw resources. Plants, algae, and several varieties of bacteria are examples. Heterotrophs are known as consumers because they devour producers or other consumers. Humans, dogs, and birds are all instances of heterotrophs.

All living things must contain genetic material. Which of the following nonliving things also has this characteristic? A. Fire B. Cell phone C. Virus D. Organic phosphates

Answers

Genetic material is the hereditary unit found in the cells of every living organism. Viruses are nonliving things that also have genetic material. Thus, option C is correct.

What are viruses?

Viruses are organisms that are living and nonliving as they reproduce when once inside the host cell and have the RNA or the DNA as the genetic material inside their capsids.

The protein shell of the virus includes one of the types of genetic material that infects the host DNA by taking control of the host machine to produce multiple copies.

Therefore, the virus is a non-living with genetic material.

Which of the following is an example of descent with modification

Answers

This will lead to change in populations over generations in a process that Darwin called descent with modification. ... One of the best examples has been demonstrated in the very birds that helped to inspire Darwin's theory: the Galápagos finches.

a mechanism for evolution; all organisms are related through descent from an ancestor; descendants accumulated adaptations; descent of all organisms from an ancestor that lived in the past; descendants accumulated diverse modifications (adaptations)

if the first one doesnt work try the second

An example of descent with modification is a bacterium that inherits a gene for antibiotic resistance, has a more significant possibility of survival. Natural selection then applies that resistance through the population, forcing scientists to come up with a new antibiotic.

What is darwin's theory of descent with modification?

Darwin described evolution as "descent with modification," the theory that species evolve over time, give rise to new species and transmit a common progenitor.

The means that Darwin proposed for evolution is natural selection.

Thus, a bacterium that inherits a gene for antibiotic resistance,  is an example of descent with modification.

A.Plastic, because it takes more energy to raise its temperature B.Iron, because it takes more energy to raise its temperature C.Plastic, because it takes less energy to raise its temperature D.Iron, because it less energy to raise its temperature

Answers

Answer:

A

Explanation:

The correct answer would be plastic because it takes more energy to raise its temperature.

The specific heat capacity of a substance is the amount of heat required to raise the temperature of the substance by one degree. The more the specific heat capacity of a substance, the more the heat required to raise its temperature.

The specific heat capacity of plastics is generally more than that of metals. Hence, metals will get heated faster than plastics under the same condition. More energy would be needed to raise the temperature of plastics when compared to metals.

the correct option is A.

Why do you seldom see fossils in metamorphic rocks?

Answers

Answer:

Metamorphic rocks have been put under great pressure, heated, squashed or stretched, and fossils do not usually survive these extreme conditions.

Explanation:

Fossils are found in metamorphic rocks because metamorphic rocks have been put under great pressure, heated, squashed or stretched, and fossils do not usually survive these extreme conditions.

What are metamorphic rocks?

Metamorphic rocks arise from the transformation of existing rock to new types of rock in a process called metamorphism. The original rock is subjected to temperatures greater than 150 to 200 °C and, often, elevated pressure of 100 megapascals or more, causing profound physical or chemical changes.

Metamorphic rocks started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form.

Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.
