Biology cell division
What are the answers to this chart
The cell spends most of the time in the interphase, which is in the G1, S, and G2 phases, and approximately 22 hours out of 24 hours, with the rest being 1–2 hours, are spent in the division phase.
What is the time spent in the cell cycle?
The cell enters the cell cycle, and the first stage is the G1 phase, where the cell grows and spends a lot of time nearly 11 hours and then the cell enters the S phase. In the S phase, the DNA replicates and spends nearly 7 hours, and then in the G2 phase, 3 to 4 hours are spent by the cell, with the remaining 1 to 2 hours spent in the M phase, also called the mitosis or division phase.
Hence, cells spend most of the time in the interphase, which is in the G1, S, and G2 phases, and approximately 22 hours out of 24 hours, with the rest being 1–2 hours, are spent in the division phase.

For which one of the following functions is parenchyma tissue particularly suited?
A. Reinforcement and support C. Elasticity
B. Exchange of gases D. Formation or root hairs
Reinforcement and support
parenchyma, in plants, tissue typically composed of living cells that are thin-walled, unspecialized in structure, and therefore adaptable, with differentiation, to various functions. The cells are found in many places throughout plant bodies and, given that they are alive, are actively involved in photosynthesis, secretion, food storage, and other activities of plant life. Parenchyma is one of the three main types of ground, or fundamental, tissue in plants, together with sclerenchyma (dead support tissues with thick walls) and collenchyma (living support tissues with irregular walls).

True or false: Despite the large explanatory ability of evolution, no direct observations of evolution have been made.
Answer:
false
Explanation:
Calculate the kinetic energy of a
30 g bullet fired at 200 m/s.
Step 1: Identify the formula needed to solve this problem.
The formula for kinetic energy (KE) is:
KE = 1/2m~v^2
m = mass
v = velocity
Step 2: Make a list of the values given in the question.
mass (m) = 30 g
velocity (v) = 200 m/s
[tex] \frac{1}{2} m {v}^{2} \\ \frac{1}{2} \times 30 \times {200}^{2} \\ 15 \times 40000 \\ = 600000[/tex]
Answer:
6 × 10⁵ J
Explanation:
Kinetic Energy of a moving mass is defined as, half of the product of it's mass and the square of it's velocity.
[tex] \boxed{ \mathsf{K.E. = \frac{1}{2} m( {v})^{2} }}[/tex]
Mass of the bullet (m) = 30 gvelocity (v) = 200 m/ s[tex] \implies\mathsf{K.E. = \frac{1}{2} \times 30 \times ( {200})^{2} }[/tex]
[tex] \implies\mathsf{K.E. = 15 \times 4 \times {10}^{4} }[/tex]
[tex] \implies\mathsf{K.E. = 60 \times {10}^{4} }[/tex]
[tex] \implies \underline{\mathsf{K.E. = 6 \times {10}^{5} J }}[/tex]
A process in which cells surround and engulf substances that are too big to pass
through the membrane is known as...
membrane pump
endocytosis
facilitated diffusion
exocytosis
Answer:
including other cells, by enclosing the particles in an extension of the cell membrane and budding off a new vesicle. During pinocytosis, cells take in molecules such as water from the extracellular fluid. Finally, receptor-mediated endocytosis is a targeted version of endocytosis where receptor proteins in the plasma membrane ensure only specific, targeted substances are brought into the cell.
Explanation:
so the answer is exocytosis
Answer:
Endocytosis
Explanation:
what molecule makes instructions for proteins and is located inside a eukaryotic nucleus
Answer:
DNA stores that info
Explanation:
In eukaryotic cells (ex. plants and animals) the DNA is found in the nucleus of the cell. Structures called ribosomes build proteins (this process is called translation).
The molecule that is responsible for carrying the instructions for the formation of protein is mRNA, which is formed inside the nucleus.
The mRNA is known as the messenger RNA because it acts as a messenger, to carry the instructions required to create a polypeptide chain.
The mRNA is formed during the process known as transcription. The mRNA is formed by the molecule known as RNA polymerase.
During the process of transcription, the genetic information gets copied as a strand of nucleotides containing adenine, uracil, guanine, and cytosine, known as mRNA, which is formed inside the nucleus.
The molecule which act as a carrier of the genetic information for the formation of proteins is known as mRNA.

Which of the following is NOT part of the non-specific immune response?
A. Inflammation
B. Phagocytosis
C. Antibodies
D. Interferons
D. Interferons are not a part of the non-specific immune response.

Interferons (IFNs) — the body's first line of antiviral defense — are cytokines that are secreted by host cells in reaction to virus infection. by using inducing the expression of hundreds of IFN-inspired genes, numerous of that have antiviral capabilities, IFNs block virus replication at many ranges.
Interferons are a circle of relatives of clearly-happening proteins which are made and secreted with the aid of cells of the immune gadget (an example, white blood cells, natural killer cells, fibroblasts, and epithelial cells).

Nitrogen oxides B) released when burning coal or gas
Volatile organic compounds C) emissions from oil refineries
Sulfur oxides D) cleaning, disinfecting, and degreasing products
The pollutants and their respective sources include the following
Carbon dioxide - This is released when burning coal or gas. The burning of
fossil fuels such as coal or gas releases the greenhouse called
carbondioxide and is responsible for increase in infrared absorption to the
earth.
Nitrogen oxide: This is made when nitrogen reacts with oxygen under the
appropriate conditions.
Sulfur oxides : This is contained in emissions from oil refineries. This is
because crude oil which is the major raw material in refineries have large
amounts of sulphur in them which reacts with oxygen to form sulfur oxides.
Volatile organic compounds: These are contained in cleaning, disinfecting,
