Asexual reproduction is not only found in the plant kingdom, what is another kingdom has examples of asexual reproduction?
A.only the fungi kingdom
B.the fungi, and animal kingdom
C.the protist and the fungi kingdoms
D.examples can be found in all the kingdoms

Answers

Final answer:

Asexual reproduction occurs in multiple kingdoms besides plants, including protists, fungi, some animals, and bacteria (Monera). Protists can reproduce asexually through binary fission, fungi often reproduce through spore formation, and certain animal species like starfish can undergo fission. Even bacterial organisms reproduce asexually by binary fission.

Explanation:

Asexual reproduction is a mode of reproduction that does not involve the exchange of genetic material and is present in various kingdoms beyond the plant kingdom. An example of a kingdom that exhibits asexual reproduction is the protist kingdom, with organisms such as protists undergoing binary fission, a form of asexual reproduction. Similarly, the fungi kingdom demonstrates asexual reproduction, with many fungi creating spores which can develop into new individuals. Certain animals also reproduce asexually; for instance, some species of sea anemones and starfish can undergo fission, splitting into multiple individuals. Even bacterial organisms, part of the Monera kingdom, reproduce asexually through binary fission.

Therefore, the correct answer to the question "What is another kingdom that has examples of asexual reproduction?" is D. examples can be found in all the kingdoms.

Aquatic plants can live in the benthic zone of shallow lakes because a. They live on decaying organisms b. The bottom is always c. They cannot tolerate salt water d. Sunlight reaches the bottom

Answers

The correct answer is option d, that is, the sunlight reaches the bottom.  

A community of organisms that thrives on, in, or close to the seafloor is known as the benthic zone. The species living in the benthic zone are known as benthos. The species dwells at the bottom of the freshwater bodies like rivers and lakes.  

The plants, which lives in the higher levels of the benthic zone are known as phytobenthos. However, these plants require sunlight in order to perform the process of photosynthesis. Therefore, these bottom-thriving plants are found in water, which is shallow enough for light to reach towards them. These plants are considered as benthic producers that signifies that they utilize the energy from the Sun to generate tissues of plants, which can be consumed by other species.

Which of these best explains why Earth’s inner core is a solid?

Low pressure due to other layers forces the particles to stay closer.
High pressure due to other layers forces the particles to stay closer.
High temperature due to other layers keeps the particles close together.
Low temperature due to other layers keeps the particles close together.

Answers

I believe the answer is high pressure due to other layers forces the particles to stay close together. It can’t be the first option because no pressure would let them act as they want to. It can’t be the third option because heat will cause the particles to move much more than they would in cold temperature. It could be the last option since cold keeps particles still but the temperature inside the earth is quite hot so the inner core wouldn’t be cold. I hope this helps!

Maxwell shoots a rubber band at his friend Jimmy. Which type of energy is converted into kinetic energy?

A.) Elastic potential energy
B.) Nuclear potential energy
C.) Chemical potential energy
D.) Gravitational potential energy

Answers

Final answer:

The energy converted into kinetic energy when Maxwell shoots a rubber band is elastic potential energy.

Explanation:

When Maxwell shoots a rubber band at his friend Jimmy, the type of energy that is converted into kinetic energy is A.) Elastic potential energy. This is because the rubber band, when stretched, stores energy due to its elasticity. Upon release, this stored elastic potential energy is converted into the kinetic energy of the motion as the rubber band flies towards Jimmy. This conversion is in accordance with the conservation of energy, which states that energy cannot be created or destroyed, only transformed from one form to another.

when the process of mitosis is correctly completed, the daughter cells should contain exact copies of all of on organisms genes. which biomolecule contains all of the organisms genes

Answers

Final answer:

The biomolecule that contains all of an organism’s genes is DNA. During the mitosis process, the genomic DNA is replicated, ensuring each daughter cell contains an exact copy of the organism's genes. In both prokaryotic and eukaryotic cells, the outcome of cell reproduction is a pair of daughter cells, which are genetically identical to the parent cell.

Explanation:

The biomolecule that contains all of an organism’s genes is DNA (Deoxyribonucleic Acid). During the process of mitosis, the genomic DNA is replicated and then allocated into the daughter cells.

This ensures that each new cell contains an exact copy of the genetic material, preserving the organism's complete genetic makeup in each individual cell. Just as you pointed out, when mitosis is correctly completed, the daughter cells should contain exact copies of all of an organism's genes.

In both prokaryotic and eukaryotic cells, the outcome of cell reproduction is a pair of daughter cells, which are genetically identical to the parent cell. This is known as cellular cloning. In bacterial cells, an analogous simpler process called binary fission occurs, where the single, circular DNA chromosome of the bacteria is replicated and passed onto the offspring cells, achieving the same outcome of identical genetic information.

which type of tropism aids plants the most in photosynthesis

Answers

Tropism is the response of an organism towards any stimuli. stimuli may be light, gravity, temperature etc. In photosynthesis plants are responded towards light, and growth of their shoot system are towards the light source. This type of tropism is called phototropism.

Answer:

Tropism refers to the response a body system of the organism produces according to an external stimulus. Plants shows tropism depending upon the type of stimuli. The stimuli can be sunlight, gravity, water or even touch. The tropism related with the sunlight is phototropism. Phototropism is a typical response of a plant shoot towards the sunlight. The plant shoots grow in the direction of sunlight, hence they show positive phototropism, whereas plant roots grow in direction against the sunlight, they show negative phototropism. Phototropism helps in availing sunlight to plants which is a necessary ingredient required for photosynthesis.

Harold makes a very diagram to help him compare and contrast mitosis and meiosis

A. Forms diploid cells
B.creates an even number of cells
C.includes two rounds of cell division
D. Duplicates body cells

Answers

Answer:- Option C - Includes two rounds of cell division.

Explanation :-

A Venn diagram is used to depict all possible relations between different sets.

In the given venn diagram-

1. The region X will consist of the features that are unique in mitosis.

2. Region Z will consist of features unique to meiosis

3. Region Y consists of features that are common to both mitosis and meiosis.

Meiosis is a process in which a cell undergoes 2 rounds of cell division known as meiosis I and meiosis II to produce 4 cells from a single cell.As a result of meiosis a diploid cell (2n) divides to form 4 haploid (n) cells. Such type of cell division is known as reductional division since, there is reduction in the number of chromosomes.The process of meiosis takes place to produce the gametes that is the sperm and the ovum.Mitosis is a type of cell division in which a single cell goes under a single round of cell division and divides to produce 2 cells.In mitosis a diploid cell thus, gives rise to 2 diploid cells.Mitosis is called equivalent division as there is no change in the number of chromosomes. The process of mitosis takes place to give rise to the cells of the body.

Thus, we can conclude that both mitosis and meiosis result in even number of cells that is 2 and 4 respectively.

Mitosis is responsible for duplicating body cells and forming diploid cells.

What is a bacteriophage? a nucleic acid that infects viruses a bacterium that infects viruses a virus that infects bacteria a protein that infects bacteria

Answers

Bacteriophage is a virus that infects bacteria.

Answer:

Bacteriophage is a virus that infects the bacteria.

Explanation:

Bacteriophages are viruses that can infect the bacteria. They have a hexagonal head and a tail. The head consists of viral DNA. The bacteriophage sits on the bacterial cell and injects the genetic material through its tail into the bacterial body. This process is called transduction. Inside the bacteria, the viral genome replicates and produces new viruses. After some time the lysogenic enzyme present in the virus breaks the bacterial wall and all the viruses emerge out. This ultimately causes the death of the bacteria and newly formed viruses again to go for a search of new bacteria.
