all cells life begin and end with this process by the process of meiosis
What is meiosis ?
Meiosis is the process where a single cell divides twice to produce four four haploid daughter cells which are otherwise called as gametes; It can occur in two substages such as meiosis I and meiosis II.
Humans have 46 chromosomes in every cell, where 23 chromosomes t came from one of our parents and 23 very similar chromosomes that came from the other parents.
Meiosis I consist of substages like Prophase I where nuclear envelope disintegrates, Chromosomes begin to condense, Spindle fibres appear.
Secondly Prometaphase I where Spindle fibres attach to the centromere followed by Metaphase I where The homologous chromosomes align at the equatorial plate, Anaphase I where he homologous chromosomes move towards the opposite poles.
Telophase I where Spindle fibres disappear, Cytokinesis I where the cytoplasm and the cell division result in 2 non-identical haploid daughter cells.

A student creates an experiment to determine the effects of oxygen on the growth of a water plant. The student fills three containers with water and adds an aquatic plant to each. Container 1 is open to the air, container 2 has a lid that prevents the exchange of air, and container 3 has a lid with a tube that pumps air into the container. After three weeks, the student observes that containers 1 and 3 have healthy green plants, while the plant in container 2 has not grown, and the leaves show browning areas.

what is the advantage of plasmolysis to the terrestrial plants?
Answers
Answer:
plasmolysis make the plants floopy, when water passes out through osmosis the plant become limb
The cell can be restored quickly to its normal turgid condition simply by returning it to a dilute medium or water.
However, plasmolysis prevents normal water balance and other functions of the plant as a whole, and thus plants cannot tolerate prolonged exposure to medium more concentrated than their own cells.

Answers
Trust me I’ve done this assignment
The greatest number of relationships between the organisms in an ecosystem is best shown in a food web. Thus, the correct option is C.
What is a Food web?A food web consists of all the food chains which are present in a single ecosystem. Each of the living thing in an ecosystem is a part of multiple food chains. Each food chain is one possible path that energy and nutrients may take as they move through the ecosystem.
For example- A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass. It is a food web that shows the many different paths plants and animals are connected.
Therefore, the correct option is C.

What does an alcoholic beverage contain that is a central nervous system depressant? 
Answers
Answer:
interferes with release of neural transmitter GABA
Explanation:
Alcohol is a central nervous system depressant, meaning it slows down brain functioning and neural activity. Alcohol does this by enhancing the effects of the neural transmitter GABA
depressants essentially "look" like the neural transmitter and so they go in and block the plasce in the brain between synapses, so when the body tries to release GABA, it appears as if it is already filled in, but in reality it is the alcohol that has filled it. once they start buidling up, they block enough that it impairs brain activity
Answer:

what do dna evidence and the fossil record indicate are the ancestors of the living cetaceans, the mammalian group that includes whales, dolphins, and porpoises?
Answers
DNA evidence and the fossil record indicate are the ancestors of the living cetaceans were land-dwelling mammals. DNA evidence allows to trace the evolutionary origin of taxonomic groups.
DNA evidence refers to the linear order of nucleotides, which can be used to trace the evolutionary origin of a particular taxonomic group.
When the linear order of DNA nucleotides is conserved, it is known as sequence homology.
Fossils are preserved remains of organisms that once lived on the Earth, which can also be used as evidence to trace the evolutionary origin of a given group.

d. all of the above
Answers
Answer:
All
Explanation:
The electron transport chain is a series of four protein complexes that couple redox reactions, creating an electrochemical gradient that leads to the creation of ATP in a complete system named oxidative phosphorylation. It occurs in mitochondria in both cellular respiration and photosynthesis.
Answer:
D
Explanation:
ATP is created in the ETC
Water is formed as a by product
The concentration gradient is what fuels the ETC. Protons (H+ ions) move across the membrane to create energy.

What happens to the membrane protein (gray) when it is activated by the signal molecules?
Answers
Answer:
The receptor protein that is embedded in the cellular membrane must accept the signal.
Explanation:
When it receives the signal this protein will then go through a conformational change. This will change the shape and how it interacts with the molecules around it. Different receptor protein will act in different ways.
Answer:
As their name implies, GPCRs interact with G proteins in the plasma membrane. When an external signaling molecule binds to a GPCR, it causes a conformational change in the GPCR. This change then triggers the interaction between the GPCR and a nearby G protein.
What happens to the membrane protein (gray) when it is activated by the signal molecules?

Answers
Research studies are often carried out using mouse. From the study, the simulated mice was said to align with the predictions from the Punnett squares. So the answer is Yes.
The reason why some of the percentages did not exactly match your predicted results because the Mice don't have large litters, so the sample size was not large enough.
If the experiment is to be done again, I can improve upon experimental design by;
Increase the number of mice bred. Examine a different trait within mice. Examine a trait in another species. Test patterns for future generations.A lot of studies is been carried out on the Genetics of the mouse. The early development of inbred lines were studied. The mouse is known to be a good tool to identify the genetic basis of both normal and disease traits.
