Which organelle is labeled I?
A:cell membrane
B:ribosome
C:endoplasmic reticulum
D:nucleus

The structure that is attached to the nuclear membrane is the rough endoplasmic reticulum (RER).

The nuclear membrane is made up of two membranes, i.e. an outer membrane as well as an inner membrane. Both these membranes contain phospholipids that are arranged in the form of a bilayer. The perinuclear space segregates the outer and the inner membrane.

The structure attached to the outer membrane, i.e. the rough endoplasmic reticulum (RER) is a cell organelle that is associated with the transport of proteins. It bears ribosomes, which are the prime site of protein synthesis, on its surface. The nuclear lamina is present beneath the inner nuclear membrane.

Darwin theory of evolution has been criticized due to its failure to explain origin and transmission of variations.

This is defined as the changes in the heritable characteristics of a biological populations over successive generations and is usually a long period of time.

Darwin's theory of evolution states that all species arise as a result of the inherited variations which increases their chances of survival in the ecosystem as a result of the varying environmental conditions from time to time.

However this theory was criticized because there was no emphasis on the origin and transmission of variations thereby making it the correct choice.

According to Newton’s third law, motion of Earth is not observable because Earth is so large, we cannot perceive the change as it is so negligible.

Newton's third law of motion states that every action has a corresponding and opposing response.

The action-reaction forces can be used to study or observe Newton's third law. When a clay ball or ping pong ball is put to the ground, the clay ball flattens on the side that meets the ground while the ping pong ball rebounds into the air.

Newton's third law states that even though the action-reaction forces on the balls and the Earth were equal in strength and directed in opposing directions during each encounter, the resulting movements of the interacting objects were dependent on their masses.

Explanation:

If you cross a pure-breeding white flower with a pure-breeding red flower, and the offspring are white with red spots and as F1-hybrid plants have a different phenotype (pink flowers) than either of the true-breeding parents, thus, it is an example of incomplete or partial dominance.

Pure-breeding offspring with pink flowers (Rr) were produced via a genetic cross between a pure-breeding with red flowers (RR) and a pure-breeding with white flowers (rr). It demonstrates that the gene for red could not entirely suppress the gene for white.

The pink flowers on the F1 hybrid plants are a different phenotypic from either of the true breeding parents. This is an illustration of partial dominance.

Nutrient transport in the biosphere differs from energy transfer because, whereas energy travels through the biosphere and could be reused, elements continuously recycled.

The biosphere, often known as that of the ecosphere, is the totality of all ecosystems on the planet. It is also known as the zone sustaining life on Earth. In terms of matter, the biosphere is essentially a closed system with very few inputs and outputs.

Energy enters the environment from the Sun as well as exits when the organisms have consumed all of it. Heat is the form in which organisms transfer energy to the biosphere.. Energy additionally enters the biosphere from the Earth's interior. It is typically in the form of heat, rather than the electromagnetic energy emitted by the Sun.

Answer:

Particles have increased kinetic energy, moving faster, overcome attractive forces, escape into vapor phase

Explanation:

The high specific heat capacity, as well as high heat of vaporization, helps in the maintenance of life on earth in various ways such as absorbing excess solar energy.

The heat of vaporization of water is high as water required 40000 joules of energy in order to vaporize one mole of water. This high heat of vaporization of water makes it resistant to temperature changes which makes life on earth possible. It causes the moderate temperature to occur in coastal areas hence sustaining life.

The high specific heat capacity of water causes aquatic animals to survive in water, even during extreme conditions. An excess amount of heat is absorbed by the water on the Earth, which is then released slowly. Hence, in this way, the specific heat capacity causes moderate temperature fluctuations for sustaining life.

A haploid (1n) cell undergoes a mitotic nuclear division followed by cytokinesis. This results in two genetically identical haploid cells.

In the field of biology, mitosis can be described as a process through which two daughter cells are formed which are exactly identical to the parent cell and to each other. The process of mitosis occurs in organisms that undergo asexual reproduction. All the somatic cells in the body divide by the process of mitosis.

If a haploid cell undergoes mitosis, hence two daughter cells will be produced that will be haploid as well as genetically identical to the parent cell and to each other. The process of cytokinesis occurs at the end of mitosis when the cytoplasm of the parent cell divides from between, forming two new identical daughter cells.

Although a part of your question is missing, you might be referring to this question:

A haploid (1n) cell undergoes a mitotic nuclear division followed by cytokinesis. this results in

Abstraction is a type of art which has no visible subject.

Abstraction is the subject of abstract art. In essence, this kind of art stimulates the senses through the representation of shape, line, color, etc., but is devoid of forms found in the actual, physical world. Abstract art is frequently more linked to and associated with an artist's aesthetic and mode of expression. Sometimes, it has an emotional theme. Non-figurative or non-objective art are some names for it.

Perspective in art relates to how real or imaginable objects (such as people, landscapes, etc.) are depicted in a visual medium like painting, drawing, or sculpture. Additionally, perspective gives artwork a tone and atmosphere.

In atmosphere , increasing global temperature has become a major cause for the rapidly melting of the polar ice into oceans. It is an example of abstraction where there is no any visible subject but it has been represented through imagination and prediction.

Tripling  of the diffusion rate would correspond to a factor 3.

Substances diffuse when they travel passively from one area of high concentration to another area of lower concentrations . During cellular transport in plants, diffusion of chemicals is crucial. The concentration gradient, membrane permeability, temperature and pressure all have an impact on the rate of diffusion . As long as there is a difference in  a substance concentration on either side of a barrier, diffusion will occur.

Gram staining helps scientists visualize the thickness of bacterial cell walls

Gram staining is a method frequently used to distinguish between two sizable groups of bacteria based on the distinct components of their cell walls. By staining these cells red or violet, the Gram stain method distinguishes between Gram positive and Gram negative groupings. The crystal violet used to stain the cells of gram-positive bacteria is retained by the presence of a thick layer of peptidoglycan in their cell walls. In contrast, Gram negative bacteria stain red because their peptidoglycan walls are thinner and don't hold on to the crystal violet during the decolorizing process, causing them to stain red.
