cytokinesis in plant cells involves the formation of
Answer:
Cytokinesis in plant cells involves the formation of the insertion of a new cell wall that separates daughter nuclei after mitosis
Cytokinesis involves the formation of the insertion of a new cell wall that separates daughter nuclei and produce two new daughter cell.
What is cytokinesis ?It is the final stage in the cell cycle, when a new daughter cells is formed from parent cell through the splitting of the cytoplasm and the separation of the two identical cells.
In Stage 1 cleavage furrow is seen where the actin filaments will begin to tighten around the cells, spindle formation occur, t the chromosomes are divided evenly between the two nuclei. The spindle possesses small structures called astral microtubules guide the alignment of the actin filaments along the future cleavage furrow.
In Stage 2 the gathering of the actin filaments occur where some protein called myosin facilitates the pulling of the actin filaments, and formation of contractile ring begins.
In Stage 3 the myosin a motor protein with the help of ATP, it is able to contract the contractile ring, deepening the cleavage furrow, causing the cell to narrow in the middle as two daughter cells form.
In Stage 4 the actual breaking of the cell membrane and the membrane quickly refuses at the broken point and two independent and identical daughter cells are produced.

Which term can be used to describe the organizational level of the brain in the human body
Answer:
Organ system
Explanation:
hope this helps
The organization level of the body involves simple and complex arrangements. The level of the brain in the body can be described by organ. Thus, option b is correct.
What is the level of organization?The arrangement of the various structures based on their complexity to form a whole organism and biosphere is called the level of organization. It starts with chemicals that make atoms and molecules.
The molecular aggregate makes the cells that bind together to form a tissue. The structurally similar tissues make the organ. The nerve, endothelial, and glial cells make the tissue of the brain.
The brain is an organ that together with the spinal cord makes the organ system called the central nervous system, or CNS. This organ system together with others makes the organism.
Therefore, option b. the brain is an organ.

Answer:
B
Explanation:
'The microorganism can be isolated and grown in a pure culture', is the only correct answer.
The statement that a microorganism can be isolated and grown in a pure culture is a part of Koch’s Postulates.
What are microorganisms?
A microorganism, or microbe is an organism of microscopic size, which may exist in its single-celled form or as a colony of cells.
The possible existence of unseen microbial life was suspected from ancient times, such as in Jain scriptures from sixth century BC India. The scientific study of microorganisms began with their observation under the microscope in the 1670s by Anton van Leeuwenhoek. In the 1850s, Louis Pasteur found that microorganisms caused food spoilage, debunking the theory of spontaneous generation. In the 1880s, Robert Koch discovered that microorganisms caused the diseases tuberculosis, cholera, diphtheria, and anthrax.
Because microorganisms include most unicellular organisms from all three domains of life they can be extremely diverse. Two of the three domains, Archaea and Bacteria, only contain microorganisms.

An experiment that can determine if an object is a living thing by taking a small sample to see if it is made of cells using a microscope. Thus, the correct option for this question is A.
What are the characteristics of living things?The characteristics of living things are as follows:
They have a tendency to construct a balance from the surrounding atmosphere through the process of homeostasis. They have the capability to grow, reproduce, and adapt to the surrounding environment. They perform an act of breathing and move from one place to another. They require food in order to derive energy.A Microscope is a laboratory instrument that is remarkably utilized in order to visualize small objects or cell samples that are too small to examine with unaided eyes. So, any living organism is definitely made of cells that are easily distinguished with the help of a microscope.

In a hypothetical population of butterflies, a dominant mutation in an allele that controls wing color has resulted in purple spots developing on the wings. The genetic change is heritable such that the offspring of butterflies who inherit at least one mutated allele will develop purple spots. The population of butterflies inhabits a windy field that contains many purple flowers. Individuals with purple spots are so well camouflaged on the purple flowers that they are eaten less frequently by predators. There are other fields with populations of the same species of butterfly nearby, but purple flowers are less prevalent in these nearby habitat areas. There are no borders between these fields and it is common for individuals from one population to be blown into another population by the wind. Despite the advantage the mutated allele confers to the butterflies in the field with many purple flowers, the mutated allele never occupies 100% of the gene pool and the population of butterflies always contains a mix of individuals with and without purple spots. What is the most likely explanation for why this trait does not spread entirely throughout the population
The movement of alleles into a population is called gene flow. The most likely explanation for why this trait does not entirely spread in the population is 'outside alleles enter the population through gene flow'.
Gene flow is caused by the migration and further reproduction of individuals in the population, or the transport of gametes from one population to another (e.g., the transport of pollen by pollinating bees).
Gene flow is an evolutionary force capable of modifying allele frequencies in a population.
In this case, despite the evolutionary advantage that the mutated allele confers to the butterflies, the frequency of this allele can not reach 100% due to the continued introduction of alleles from other populations (i.e., due to gene flow).

1. State Mendel's Law of Inheritance.
2. What are the two alleles for flower color in snapdragon?
3. State the Law of Non-Mendelian Inheritance in snapdragon.
Answer:
1
Explanation:
he was able to find chromosomes in plants
Gregor Mendel's research on pea plants led him to the fundamental ideas of inheritance. He came to the conclusion that genes are inherited as distinct, paired units from each parent.
What is Non-Mendelian Inheritance?
Inheritance of features with a more complicated genetic base than one gene with two alleles and total dominance is referred to as non-Mendelian inheritance.
One allele may not always be dominant over another, resulting in a phenotype that falls between the two parents in certain people.
Incomplete dominance is the name given to this inheritance pattern. Snapdragon flowers, for instance, exhibit partial dominance.
When both alleles are present at the same time, this pattern of inheritance is referred to as partial dominance, since neither allele is totally dominant over the other.
Therefore, red and white snapdragons cross to produce exclusively pink progeny.
