Answer:
the cytoplasm is partitioned by the construction of a new cell wall, the cell plate, inside the cell.
Cytokinesis refers to cytoplasm and other organelles are physically separated to create two unique daughter cells. It completes the process of cell division and is the last stage of the cell cycle.
The cytoplasm of the cell, together with all the required organelles and cellular parts, are divided between the two daughter cells during cytokinesis. This guarantees that each new cell will have the framework and resources it needs to operate effectively.
Because plant cells have a cell wall, the specifics of cytokinesis can vary between animal and plant cells. The stiff cell wall in plant cells precludes the same kind of cleavage process that occurs in animal cells. Instead, in the center of the dividing cell, a structure known as the "cell plate" develops. Two distinct plant cells eventually arise as a result of the cytoplasm and other contents of this cell plate being divided as it expands.
Animal cells typically undergo a process known as cleavage in order to undergo cytokinesis. Just below the cell membrane, a protein ring that can contract slowly like a drawstring forms, pinching the cell into two distinct daughter cells.

Answer:
Option A, 9:7
Explanation:
Given,
Genotype of A-B- have purple color
A-B- have genotype AABB, AaBb, AaBB, AABb
While genotype of A– bb, aa B–, and aa bb have white flowers
A– bb have genotype - AAbb, Aabb
aa B– have genotype aaBb, aaBB
Cross between Aa Bb and AaBb will give following offspring
AB Ab aB ab
AB AABB AABb AaBB AaBb
Ab AABb AAbb AaBb Aabb
aB AaBB AaBb aaBB aaBb
ab AaBb AAbb aaBb aabb
So the possible genotypes and their corresponding phenotypes are
AABB-1 (Purple)
AABb-1 (Purple)
AaBB-3 (Purple)
AaBb -4 (Purple)
AAbb-2 (White)
Aabb-1 (White)
aaBB-1 (White)
aaBb-2 (White)
aabb-1 (White)
Purple : White = 9:7
(B) species
(C) class
(D) genus
(E) order
Current populations of organisms vary significantly depending on the species and ecosystem. For instance, the population of pine trees in a forest is determined by ecological factors. Total known species represent a fraction of entire biodiversity, with limitations due to resources and political will.
The current population of an organism varies greatly depending on the species and its ecology. For instance, in a forest, each pine tree is an organism and all these pine trees together make up a population. The number of individuals in this population would be dependent on various ecological factors such as availability of resources and interactions with other species.
Furthermore, it's important to note that our current knowledge of species that inhabit the planet is quite limited, and always will be, due to lack of resources and political willpower. Estimates suggest that the known eukaryote species, approximately 1.5 million, account for less than 20 percent of the total eukaryotes present on earth (around 8.7 million species, according to one estimate). For prokaryotic species, current numbers are largely speculative and scientists agree that we have only begun to catalog their diversity.

Answer:
A disease in the population of rabbits. Trapping has severely reduced the population of rabbits in an ecosystem, as shown in the bar graph. ... The grass, rabbit, snake, and hawk populations will all decrease rapidly. The grass population will decrease rapidly and the snake population will increase rapidly.
An ecosystem consist of various biotic and abiotic factors which interact with each other. A grassland ecosystem is a terrestrial ecosystem which have grass as the main producers (dominant) living thing.
A grassland ecosystem is a type of terrestrial ecosystem in which grasses and the herbaceous plants are the dominant species. Grass controls the grassland ecosystems as they are the main producers of the ecosystem with few or no trees where there is not favorable conditions for a forest. It is more like a dry and desert ecosystem. Therefore, it is also called as a transitional landscape.
The four important abiotic components of grassland ecosystem includes climate, parent material and soil, topography, and natural disturbances. Climate includes the rainfall pattern, temperature and wind patterns of a particular area.
Biotic Factors in the Grassland ecosystem include Plants, Insects (Invertebrates), Grazers, and Predators.

Answer:
Forest Ecosystem
An ecosystem is composed of two main components: biotic and abiotic factors. Biotic factors are the living parts of the ecosystem, such as plants, animals, insects, fungi, and bacteria. Abiotic factors are the non-living parts of the ecosystem, which influence the size and composition of the living parts: these are components like minerals, light, heat, rocks, and water.
Biotic Factors by Type
The most obvious features of any forest ecosystem are its trees, the dominant biotic feature. They dominate the ecosystem: both in terms of visibility and in terms of biomass. However, they are only one type of organism living in a forest. Other biotic factors include:
shrubs, flowering plants, ferns, mosses, lichens, fungi, mammals, birds, reptiles, insects, worms, microbes
Abiotic Factors by Type
The most important abiotic feature of a forest ecosystem may not be obvious, despite its ubiquity and importance: sunlight. Tangible abiotic factors include soil, minerals, rocks, and water. But abiotic factors can be intangible, such as temperature, other types of radiation, and the chemistry of soil and water.
Biotic Factors by Function
Ecologists frequently group an ecosystem's factors by what role they play in the system, rather than by what particular species they are. This is known as a functional classification.
These functions relate to the movement of energy through an ecosystem, and trees — along with other photosynthetic plants — are the chief primary producers. This means that trees convert the sun's energy into food energy, which is then used by other members of the ecosystem.
These other members of the ecosystem can also be categorized. Primary consumers are, for example, herbivores that eat the primary producers. Secondary consumers are the carnivores and omnivores that eat the primary producers. Decomposers are the scavengers, microbes, and fungi that consume the droppings and the carcasses of other organisms.
Abiotic Factors by Function
The abiotic factors of a forest fall less obviously into functional classifications, but keep in mind that the energy transferred among the various biotic categories is itself a foundational abiotic element. This energy occurs in the form of solar radiation, which includes both visible light and heat (infrared).
Primary producers (plants like trees and shrubs) convert the light into carbohydrates, a form of energy that can be consumed by other organisms. The function of other abiotic factors relies on the minerals they contain, such as the nitrogen in the soil or the hydrogen in water molecules.
