Biology question 3
A single muscle cell can contain dozens of nuclei. Which stage of the cell cycle is the not completing? How do you know?
A muscle cell contains many nuclei due to cellular fusion, which is the combination of multiple progenitor cells. It does not complete the cytokinesis stage of the cell cycle, which normally leads to the division of the cell and its nucleus into two separate cells.
Explanation:A single muscle cell, known as a myocyte, generally contains many nuclei due to a process called cellular fusion. This process involves the combination of numerous progenitor cells, each with a nucleus, to form a single muscle cell with multiple nuclei.
The stage of the cell cycle that the myocyte is not completing is cytokinesis. Cytokinesis is the phase in which the cell physically divides at the end of mitosis to form two identical daughter cells. If a cell does not undergo cytokinesis, it will not separate, and instead, it may form a cell with multiple nuclei, as seen in muscle cells.
In summary, muscle cells contain multiple nuclei due to the lack of cytokinesis following mitosis, leading to the fusion of multiple cells into a single cell body.

The synthesis of giant molecules from components of repeating units is _____. polymerization hydrolysis
Answer: The correct answer for the fill the blank is polymerization.
Polymerization is the process of formation of large molecule from the components of smaller repeating units. A chemical bond is formed between smaller units. The smaller repeating units are called as monomers and the giant molecule formed in this process is called as polymer.
Example- DNA ( deoxyribonucleic acid) is a giant molecule or polymer, which is formed by the joining of individual smaller units called as dNTP ( deoxyribonucleoside triphosphate). Thus, formation of DNA is a polymerization reaction.

n a cross between two heterozygous individuals (eg. Rr X Rr), the expected phenotypic ratio of the offspring would be
A)1:2:2:1.
B)1:2:1.
C)1:1.
D)3:1.
The expected phenotypic ratio of the offspring is B) 1:2:1.
To understand the expected phenotypic ratio of the offspring from a cross between two heterozygous individuals (Rr x Rr), we can use the Punnett square method. Here, 'R' represents the dominant allele for a trait, and 'r' represents the recessive allele.
When we set up the Punnett square for the cross Rr x Rr, we get the following:
```
R | r
---------
R | RR | Rr
---------
r | Rr | rr
```
From this Punnett square, we can determine the genotypic ratio of the offspring:
- RR (homozygous dominant): 1
- Rr (heterozygous): 2
- rr (homozygous recessive): 1
The phenotypic ratio is determined by the number of individuals that express a particular trait, regardless of their genotype. Since the dominant allele 'R' will mask the presence of the recessive allele 'r' in the heterozygous (Rr) individuals, the phenotypic ratio will be:
- Dominant phenotype (RR and Rr): 1 (RR) + 2 (Rr) = 3
- Recessive phenotype (rr): 1
Therefore, the expected phenotypic ratio is 3:1, which corresponds to option D. However, this is not the correct option for the given question, as the question asks for the phenotypic ratio, not the genotypic ratio.
The phenotypic ratio is actually 1:2:1, which corresponds to the number of offspring with the dominant phenotype (RR, which is 1), the number of offspring with the dominant phenotype (Rr, which is 2), and the number of offspring with the recessive phenotype (rr, which is 1). This ratio reflects the number of different genotypes that will have the same observable trait (phenotype).

Which sequence shows a decreasing level of complexity?
Hello. This question is incomplete. The full question is:
" Which sequence shows a decreasing level of complexity? 1) organs organism cells tissues , 2) organism cells organs tissues , 3) cells tissues organs organism , 4) organism organs tissues cells"
Answer:
4) organism organs tissues cells
Explanation:
The order "organism, organs, tissues, cells" shows the levels of organization in a decreasing level of complexity.
There are several hierarchical levels of organization among living beings, starting with atoms and ending with biomes. Each of these levels is a matter of study for biologists. These levels are:
Atoms: a very small part of matter. Atoms are divided into protons, neutrons and electrons. The joining of these atoms forms matter in its solid, liquid and gaseous states. Molecule: the molecule is a junction of atoms. The molecules are diverse substances and are formed by different atoms (H2O) or by the same atoms (O2); Organelle: small organ-like structures that are present in animal and plant cells. They help to carry out the vital functions of cells; Cell: cells are the functional units that make up animal and plant organs. They perform breathing and reproduction in addition to saving the genetic information of beings; Tissue: is the visible part of the organs, formed by a group of plant or animal cells. Our skin, for example, is a type of tissue. Tissues are responsible for storing cells, blood vessels, making excretions such as sweat.Organs: set of tissues. The organs perform various types of functions: the heart pumps blood, the stomach helps with food, the small intestine absorbs substances. System: set of interconnected organs. Our digestive system, for example, has a mouth, tongue, esophagus, stomach and intestine. Organism: set of systems that form a living being, for example, the human being, a lion, a plant.What is ability of organisms to survive and reproduce on the range of our men to circumstances?
Biomes that are found near the equator or near mountains ranges and have high relative humidity and lots of rain are called A) deserts.
B) rain forests.
C) temperate forests.
D) deciduous forests.
Answer: B) rain forests.
Explanation:
The tropical rainforests are found near the equator, near mountain ranges and exhibit high humidity and lots of rain. These areas receives maximum sunlight which is responsible for the high temperature in the region because of which the evaporation of the available water body takes place at a faster rate hence result in immense rainfall.

If a mutation occurs such that photosystem ii no longer functions as efficiently as it should, what might be most directly affected?
Out of the following given choices;
a) The amount of oxygen produced
b) The rate of ATP synthesis by ATP synthase in the chloroplast
c) The rate at which NADPH is produced
d) The rate at which the protons are transported into the thylakoid
The answer is; A
The photosystem captures energy from sunlight and uses it to split a water molecule. After splitting the water molecule (by taking an electron), the protein complex transports the electron to plastoquinone. The splitting of water molecules results in evolving of oxygen molecules. The hydrogen is what is used to reduce carbon dioxide to glucose.
The amount of oxygen to be generated will be affected directly.
Further Explanation:
Photosystem is responsible for photosynthetic light reactions of algae, bacteria, and plant.
There are 2 photosystems:
Photosystem-1 Photosystem-2
Photosystem-1 plays the main role and utilizes light energy in order to generate high energy carriers such as NADPH as well as ATP. They use p700 photoreceptor and they absorb light of longer wavelength. In this photolysis of water does not occur.
On the contrary, photosystem-2 refers to the protein complex found in the light-dependent reactions of the oxygenic photosynthesis. They present in the thylakoid membrane of the plants, cyanobacteria, and algae. They absorb the shorter wavelength of light. In photosystem 2 photolysis of water occur.
The photosystem absorbs the energy from the sunlight and utilizes it to break the water molecule. After this, the protein complex sends the electron towards the plastoquinone. The breaking of the water molecules leads to the evolution of oxygen molecules. The water is what is utilized to lower the carbon dioxide to a glucose molecule.

Where does translation take place? where does translation take place? golgi apparatus ribosome endoplasmic reticulum nucleus?
Translation takes place in ribosomes located in the cytoplasm of the cell.
Explanation:Translation is the process of protein synthesis where information coded in the mRNA is used to produce a specific amino acid sequence. It takes place in the ribosomes located in the cytoplasm of the cell. Ribosomes are composed of rRNA (ribosomal RNA) and proteins, and they are responsible for reading the mRNA and assembling the amino acids into a polypeptide chain.
