Explanation:
Nuclear fusion is the process by which two or more atomic nuclei join together, or “fuse,” to form a single heavier nucleus. During this process, matter is not conserved because some of the mass of the fusing nuclei is converted to energy, which is released. Fusion is the process that powers active stars, releasing large quantities of energy.

Meiosis occurs in a series of different phases and creates genetically unique reproductive cells.
Which process helps make meiotic cells genetically different and occurs during prophase I, but not during prophase II?
fertilization
independent assortment
crossing over
chromosome replication
Answer:
Meiosis occurs in a series of different phases and creates genetically unique reproductive cells. The process which helps make meiotic cells genetically different and occurs during prophase I, but not during prophase II, is crossing over (C). Crossing over is the exchange of genetic material between two homogenous chromosomes. It is one of the final phases of prophase I. This process is called synapsis. It occurs when the matching regions on the matching chromosomes break and then reconnect to the other chromosome .
The process that helps to make meiotic cells genetically different and occurs during prophase I is called crossing over.
Crossing over, also known as recombination, is the interchange of genetic material between non-sister chromatids of homologous chromosomes.This process (crossing over) occurs in Meiosis I, specifically during Prophase I.Crossing over during Prophase I and the independent assortment of homologous chromosomes during Metaphase I represent meiotic processes that help to increase genetic variation in gamete (sex) cells.In conclusion, the process that helps to make meiotic cells genetically different and occurs during prophase I is called crossing over.

During a lion and cub moment, Mufasa says to Simba, “Everything you see exists together in a delicate balance…..respect all creatures”. How can this quote be related to the concept of the food web, pyramid of energy, and/or the pyramid of numbers? What could happen if this balance is not respected? Indicate a scene in the movie that is an example of this loss of balance.
Answer:
The quote refrences to the fragility of our enviorment and how that balance is to not be disrupted. That no matter how small,every detail affects that balance and is not to be tampered with. It is the same in the food chain,the elimination of even the smallest of species can have devastating effects on an ecosystem. That is why it is important to preserve resources and respect all life. an example of that balance being disrespected in the movie would be the scene where the once beautiful valley was barren and dry due to the hyenas destroying and using up all of the resources, thus destroying the balance of life and bringing famine to their lands.
Explanation: The circle of life man
When a balance is not respected then it leads to destruction of the whole ecosystem not a single organism.
What is the relation of the quote?This quote is related to the concept of the food web, pyramid of energy, and the pyramid of numbers because every organism is dependent on other organism for its survival. If that organism is eliminated from the ecosystem, then the organism that feeds on it also die.
If this balance is not respected and maintained then the whole ecosystem is destroyed because every organism is dependent on othe organism.
So we can conclude that when a balance is not respected then it leads to destruction of the whole ecosystem not a single organism.

Larger the size of an organism bigger the size of its cells. Do you agree with this statement? Give scientific reasons.
Answer:
Disagree.
Explanation:
Though some cells are bigger than others, they do not scale with size. For example if you look at skin cells on a dog they would be similar in size to a skin cell from a human. When an animal or species is bigger it is usually just made from more cells.

Can cells that are haploid (single set of chromosomes) undergo meiosis?
1. Yes, haploid cells have a single set of chromosomes that can be altered.
2. No, haploid cells have only one set of chromosomes that cannot be reduced.
3. No, haploid cells have only one set of chromosomes that can be multiplied.
4.Yes, haploid cells have a single set of chromosomes that can be transferred.
Answer:
Haploid cells cannot undergo meiosis because haploid cells have only one set of chromosomes that cannot be reduced (option 2).
Explanation:
Meiosis is the process of reductional cell division in which, from a diploid cell, four haploid cells —called gametes— are obtained.
The process of meiosis comprises two successive divisions, meisosis I and II, with the result explained above.
The haploid cells are the final result of the complete meiosis process, necessary for procreation in species with sexual reproduction, and cannot undergo a process of reductive division.
No, haploid cells cannot undergo meiosis because meiosis is the process of cell division that produces haploid cells from diploid cells.
Meiosis is a specialized form of cell division that occurs in sexually reproducing organisms to produce gametes (sex cells) with half the number of chromosomes as the parent cell. It involves two rounds of division, known as meiosis I and meiosis II, resulting in the formation of four genetically unique haploid cells.
Haploid cells contain only one set of chromosomes, while diploid cells contain two sets. In meiosis, diploid cells undergo recombination and reduction division to produce haploid cells. During meiosis I, homologous chromosomes pair up, exchange genetic material through crossing over, and separate, resulting in two haploid cells with mixed genetic information. In meiosis II, the sister chromatids of each chromosome separate, leading to the formation of four haploid cells.
Haploid cells, once formed through meiosis, cannot undergo further meiosis because they already possess the reduced number of chromosomes characteristic of gametes. Instead, haploid cells participate in the process of fertilization, where they combine with another haploid cell to form a diploid zygote, which will then undergo mitosis to develop into a multicellular organism.
Therefore, option 2 is the correct answer: No, haploid cells have only one set of chromosomes that cannot be reduced.

Question
Answer:
A scientist's response to the increase in food poisoning sick patients should be examining the type and source within the foods consumed.
Explanation:
Food poisoning involves the effects that decomposed or contaminated food can have on a group of people who eat it, and can cause illness in all or most individuals.
Although patients' symptoms should be treated and preventive education provided, the best course of action for a scientist is to investigate the cause.
The response of a scientist to the increase in food poisoning cases is to determine the type and source of food, as well as the nature of the alteration it has -decomposition, contamination, bacteria- in order to eliminate the source and avoid new cases.
The other options may be valid in the face of the appearance of food poisoning cases, but they are not the best procedure with which a scientist would respond.How does pinocytosis work?

How can a diet that is 90% carbohydrates support the same amount of protein in the human body as a diet that is only 15% carbohydrates?
Answer:
Due to increase or decrease in the concentration of carbohydrates have no effect on protein concentration.
Explanation:
A diet having 90% carbohydrates support the same amount of protein in the human body as a diet that is only 15% carbohydrates because with the increase or decrease of carbohydrates in the diet does not increase the amount of protein. Protein and carbohydrates are two different things, proteins broken down into amino acid that is utilize by the body for making muscles while carbohydrates are broken down into glucose that is used by the body for performing daily activities.
90% carbohydrates support the same amount of protein in the human body as a diet that is only 15% carbohydrates as it helps to balance the amount of carbohydrates and protein needed for the body to perform its activities.
CarbohydratesBoth carbohydrates and proteins have a vital role in good health. Proteins in our body help to maintain healthy skin, bones, hair and muscles. Carbohydrates give energy to our body parts like the brain, kidney and heart to function properly.
If your diet has only 15% of carbohydrates, then the body will take any measure to get the energy it required for the proper functioning of body parts. The body tries to break down the proteins (that you eat)chemically until it act like carbohydrates.

Explanation:
Describe the origin and fiber composition of (1) ventral and dorsal roots, (2) the spinal nerve proper, and (3) ventral and dorsal rami.
Answer:
A dorsal root (sensory or afferent) and a ventral root (motor or efferent) originate from the medulla. They unite near the intervertebral foramen, forming the spinal nerve. The nerves emerge from the intervertebral foramen, dividing into ventral and dorsal ramus.
Explanation:
The nerve is a set of nerve fibers perceptible to the naked eye and wrapped in connective tissue. They are made up of roots, trunks and nerve branches (some of them come together and form plexuses).The spinal nerve originate from the spinal cord in the form of 31 pairs: 8 cervical, 12 thoracic, 5 lumbar, 5 sacral and 1 coccygeal. They emerge from the spinal cord through two roots: dorsal roots, made up of sensory fibers that come from the sensory neurons of the spinal ganglion and that penetrate the spinal cord through the posterolateral and ventral root, made up of motor fibers, coming from the motor neurons of the anterior horn and visceral of the lateral horn of the gray matter of the spinal cord. This root exits the spinal cord through the anterolateral groove, then joins the posterior root to form the spinal nerve, which exits the vertebral canal through the corresponding intervertebral foramen.Each spinal nerve, after leaving the vertebral canal, emits two primary ramus: the dorsal ramus, contains somatic and visceral fibers that go to the skin and muscles of the back and the ventral ramus, which supplies the ventrolateral surface of the skin, body wall and extremities.
