Explanation:
A plant cell consists of one large vacuole that maintains the shape of the cell and stores nutrients. Animal cells, on the other hand, have multiple smaller vacuoles. Both plant and animal cells have a cell membrane, but only the former has a cell wall.
which of the following events does not occur in spermatogenesis
Answer:
The mitochondria and Golgi apparatus are packaged into the head of the sperm.
Explanation:
Spermatogenesis is the production of male germ cells. Sufficient stimulation with sex hormones, especially testosterone, and a lower temperature, which is achieved by placing the testicles in the scrotum, are required for the correct course of spermatogenesis. Sperm production has three phases: reproductive, growth and maturation. At the beginning of sperm development are spermatogonia, which are male primordial cells. They have a spherical shape and are located at the edges of the seminal canals. Spermatogonia is mitotically divided. On the one hand, in order to preserve their numbers, and on the other hand, their division produces primary spermatocytes, which lie above the layer of spermatogonia. Primary spermatocytes are diploid, but after the first meiotic division, haploid secondary spermatocytes are formed from them. They still have double chromatids, so a second meiotic division soon occurs, the product of which is spermatids. Spermatids are already fully haploid and do not divide further. Spermatids then undergo a process of spermiogenesis, in which the nucleus condenses, forming a flagellum and losing most of the cytoplasm and some organelles. Immature sperm travel through the seed-forming canals to the epididymis, where they are definitively matured. This whole process takes about 72 days.
Provide one example of Mutualism.
You must explain: The two organisms, how they both benefit, and any other necessary information to explain their interaction.Immersive Reader
Answer:
Cattle and egret
Explanation:
Mutualism is a type of symbiotic relationship involving two organisms whose actions cause them to benefit from one another. In other words, both organisms do one another a favour, hence, the relationship is said to be MUTUAL.
- An example of a mutualistic relationship is that of CATTLE AND EGRET. Cattle gets infested by certain parasites like ticks and fleas, which feeds on their blood. Egrets are bird species that flock around cattle to feed on these insect parasites. This relationship is mutual because, egrets help the cattle get rid of their parasite problem (cattle benefits) while the cattle provides food for the egrets when they harbor these parasites on their body (egret benefits).
What types of cells make up the nervous system?
Answer:
Neurons
Explanation:
Answer: Red Blood Cells
Question 21
Neurons of the cerebral cortex never dip into the medulla.
O True
O False
Answer:
False
Explanation:
The cerebral cortex refers to the outer layer of the brain. This layer is formed by a thin film of nervous tissue that surrounds the surface of the cerebral hemispheres, with primates having a much more developed cerebral cortex than other animals.
the cerebral cortex is a thin layer of neurons and neuronal connections which is embedded in the neocortex(the neuronal cells of the cerebral cortex which form in the deep layer), it is not homogeneous, since it is made up of six layers of cells, each with specific and specific functions.
Cancer is a disease of the cell cycle. Which of the following is NOT true of cancer cells? Cancer cells engage in uncontrolled cell division. Cancer cells ignore signals that should cause them to stop dividing Cancer cells exit the cell cycle (stop dividing) when abnormal cellular activity is deteced.
Answer:
Cancer cells exit the cell cycle (stop dividing) when abnormal cellular activitiy is detected is your answer.
Explanation:
This is the answer because cancer cells are what cause tumors which are basically when cells are dividing uncontrollably. Cancer cells never ever exit cell cycle they are always repeating it causing abnormal production of cancer cells so the last answer cancer cells exit the cell cycle is false making it the answer for this question.

Explanation:
Answer: 3. anticodon, 4. amino acid, 5. In stage one, glucose is broken down in the cytoplasm of the cell in a process called glycolysis. 6. The process of gene expression involves two main stages: Transcription: the production of messenger RNA (mRNA) by the enzyme RNA polymerase, and the processing of the resulting mRNA molecule. 7. 64. 8. One codon, AUG, specifies the amino acid methionine and also acts as a start codon to signal the start of protein construction. There are three more codons that do not specify amino acids. These stop codons, UAA, UAG, and UGA, tell the cell when a polypeptide is complete. 9. In the process of translation, the mRNA attaches to a ribosome. Next, tRNA molecules shuttle the appropriate amino acids to the ribosome, one-by-one, coded by sequential triplet codons on the mRNA, until the protein is fully synthesized. When completed, the mRNA detaches from the ribosome, and the protein is released. plzz mark brainliest

Alkali substances has a pH greater than 7 hence it follows that the lye in soap has a pH over 7.
What is corrosion?
The term corrosion has to do with the waering away of a metal surface due to the action of oxidation. Hence the term applicable is corrosion.
The bases are know to be have a bitter taste and are slippery to touch hence the correct response is bases.
Water is a neutral substance, in the pH scale, a neutral substance has a pH of 7 hence the pH of water is 7.
Sulfuric acid is an acid and acids have a pH that is below 7 hence the pH of sulfuric acid is under 7.
Given the fact that alkali substances has a pH greater than 7, it follows that the lye in soap has a pH over 7.

Utility companies use _ per month, to determine how much energy is being used.
What goes in the blank ?
Answer:
Kilowatt-hour
Explanation:
Energy refers to the amount or quantity of power which is being consumed by an individual, group of people or organization over a specific period of time. As the consumers continue to use energy, they're being charged or made to pay a utility fee regularly for their amount of consumption, which is usually calculated hourly (kilowatts hour or kwh).
Hence, power utility companies use kilowatt-hour (KWh) per month, to determine how much energy is being used.
In the late 1980s and early 1990s, the percentage of Icelandic children whose bacterial infections were caused by bacteria resistant to penicillin rose at an alarming rate. After public health officials initiated a campaign to reduce the use of penicillin, resistance dropped off. This observation is consistent with the hypothesis that ________.
Answer:
The correct answer would be - "bacterial populations evolve in response to the selection pressure imposed by antibiotics".
Explanation:
The given information provided in the question about the bacterial infection supports the hypothesis that the bacterial population shows the evolution in response to the selection pressure caused by the antibiotics due to the fact that bacteria increased resistance gradually with time. This resistance towards antibiotics increased the percentage of bacterially infected children in the late 1980s and early 1990s.
In this case, the population of bacteria having resistance genes is selected to evolved selected to increase their offsprings.

What is your opinion of the ethics of manipulating crop plants in such a way?
Answer:
- The co-worker is wrong, it is indeed possible
- Genetically engineered plants may represent a milestone to alleviate hunger in the world
Explanation:
During photosynthesis, plants use carbon dioxide (CO2) from the air and water (H2O) from soil and rain in order to produce oxygen and glucose, which is a sugar (molecular formula C6H12O6). Subsequently, plants release oxygen into the air and store energy (and carbon compounds) in the form of glucose. In consequence, an increase in the photosynthetic rate is directly associated with an increase in both the production of oxygen and glucose. On the other hand, genetically engineered plants can help to reduce hunger in developing countries. In consequence, it is acceptable to develop genetically modified plants as long as contemplating regulatory measures aimed at producing safe products (for example, by avoiding the introduction of genetically engineered genes into wild crop populations).
