If a parent cell has 48 chromosomes, how many chromosomes will each daughter cell have after mitosis and cytokinesis occurs? 96 chromosomes 48 chromosomes 12 chromosomes 24 chromosomes
Answer:
48 chromosome
In mitosis, the daughter cells have the same number of chromosome as the parents cell in the form of chromatids( as chromatids sister had separated during anaphase ).
I suggest you to learn( differentiate) about the term like chromatin, chromatid, chromosome, sister chromatids, homologous chromosomes so you can mastered this chapter.
Good luck!

Answer:
1. About 10^-6
2. The growth of roots is regulated by auxin concentration, with concentrations greater than resulting in smaller roots. Concentrations lower than 10^-8.5 encourage roots to develop more as concentrations increase, up to a concentration of 10^-8.5.
3. Auxin, I would apply at a concentration of around 10^-8.5 to generate the biggest carrot roots.
Explanation:
Auxins are growth hormones that are found in root tips and shoots, causing the roots to grow bigger as concentrations rise and causing the carrots to grow larger.
What type of organisms use brumation?
a. Ectotherms
b. Endotherms
c. All hibernating organisms
d. All tortoises
Answer:
Brumation is a type of dormancy used by some ectothermic (cold-blooded) animals, such as reptiles, to survive periods of extreme weather conditions, usually winter. By brumating, these animals can lower their metabolism, heart rate, and respiration to conserve energy.

what stucture is attached to the nuclear membrane
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.

What are cells?The smallest unit that can sustain life on its own and makes up all living things, including the body's tissues. The cell membrane, the nucleus, and the cytoplasm are the three primary components of a cell. The substances that enter and leave the cell are governed by the cell membrane, which encloses the cell. They give the body structure, absorb nutrients from meals, turn those nutrients into energy, and perform certain tasks.

A disruption of our 24-hour biological clock as a result of either overexposure or underexposure to light is referred to as desynchronization.
What is a biological clock?Circadian rhythm is another term for biological clocks.Circadian rhythms are changes in an organism's physical, mental, and behavioral changes that occur on a 24-hour cycle.These natural processes are primarily affected by light and dark and affect nearly all living things, including animals, plants, and microbes.Endogenous biological clocks regulate physiological activity and behavior patterns on multiple time scales. Circadian rhythms are cycles of change that occur within 24 hours and include the sleep/wake cycle, body temperature change, and hormone release such as melatonin and cortisol. Melatonin, a hormone that helps regulate circadian rhythms, is secreted by the pineal gland.

Mutation have made DNA repair more efficient
In a study published describe blasting E. coli bacteria with ionizing radiation one per week, caused the bacteria to become radiation resistant. In doing so, they have became genetic mutations and mechanisms underlying this resistance.with time , as the bacteria have become resistant, the researchers have been able to elevate the level of radiation to which they exposed the bacteria mutations . The study took a deep dive into the mutations they have collected after 50 cycles (meaning the bacteria were irradiated 50 times).While the total mechanisms, such as increased DNA repair, are the same as in naturally resistant bacteria, many of the mutations that caused those changes have never been seen before mutations .

By what factor would the rate of diffusion change if membrane thickness doubled?
Tripling of the diffusion rate would correspond to a factor 3.
What are the factors which affects the rate of diffusion ??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.

Why was motion of Earth not observable after the action-reaction event with the ping pong ball or clay ball?
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.

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

Which type of art has no visible subject?
A major concern about increasing global temperatures is that a large portion of polar ice could detach and melt into the ocean.
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.

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.
