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.

The relatively large number of new mutations that occur in the human genome in each generation is tolerable because: ______________
a. humans have excellent protein repair mechanisms.
b. compared to other organisms, changes in human proteins have relatively small effects on their cells' structures and functions.
c. humans have excellent DNA repair mechanisms.
d. most of the human genome is noncoding DNA, so few mutations affect human proteins.
e. most of the mutations occur in somatic cells, not germ cells.
Answers
Answer:
The believe the correct answer is option E.
The relatively large number of new mutations that occur in the human genome in each generation is tolerable because: most of the human genome is noncoding DNA, so few mutations affect human proteins. Therefore, the correct option is D.
What is a human genome?A human genome refers to the complete set of sequences of the nucleic acids that are present in the humans. The human genome contains a relatively large amount of noncoding DNA, which does not code for proteins and is therefore less subject to selective pressures.
Option A, humans have excellent protein repair mechanisms, and Option C, humans have excellent DNA repair mechanisms, are partially true, but do not fully account for the tolerability of new mutations in the human genome.
Option B and E are also not true, as changes in human proteins have relatively small effects on their cells' structures and functions, is not entirely true. Therefore, the correct option is D.

The first fuel Paul’s body uses is ________________________ from Paul’s last meal, which are stored in his _____________ & his ______________ (technically the bits in his BLOOD are used up before that even). The body turns them into ____________, which is burned in ____________. That fuel lasts Paul about ________________.
Answers
1. The first fuel Paul’s body uses is carbohydrate, which is generated from Paul’s last meal.
2. These carbohydrates are stored in his liver and muscles (technically, the bits in his blood are used up before that even).
3. The body turns the carbohydrates into glucose, which is burned in mitochondria during an aerobic cellular respiration.
4. That fuel lasts Paul about 3 miles, 40 minutes ([tex]\frac{2}{3} \;hours[/tex]).
A fuel can be defined as the resources that power the body of a living organism such as a human being. Also, the three (3) main types of fuel that power the human body include the following:
OxygenWaterFoodFat is a nutritional element of food and it is beneficial to the body of a living organism because after the body exhausts its carbohydrates, it then uses its own fat as a fuel to power the body.
In this context, the first fuel Paul’s body uses is carbohydrate, which is generated from Paul’s last meal. These carbohydrates are stored in his liver and muscles (technically, the bits of carbohydrates in his blood are used up before the storage).
Furthermore, the body turns the carbohydrates into glucose, which is burned in mitochondria during an aerobic cellular respiration. Also, the fuel would only last Paul for a distance of about 3 miles, 40 minutes ([tex]\frac{2}{3} \;hours[/tex]).

Homeostasis is necessary for a cell to survive. What is the definition of homeostasis
Answers
Answer:
Homeostasis is the process of maintaining a constant internal environment suitable sustaining life.
Homeostasis continues to maintain ideal environment for enzyme action and all cell functions throughout the body.
Why homeostasis is necessary?It is the preservation of a constant internal environment in the face of changing internal and external conditions. These include blood glucose concentration control in the human body.
A series of control mechanisms at the organ, tissue, or cellular level maintain homeostasis.
Substrate supply, activation or inhibition of individual enzymes and receptors, enzyme synthesis and degradation, and compartmentalization are examples of control mechanisms.
The liver, pancreas, kidneys, and brain (hypothalamus, autonomic nervous system, and endocrine system) all contribute to homeostasis.
The liver is in charge of metabolizing toxic substances and maintaining carbohydrate metabolism with pancreatic signaling.
Thus, homeostasis is necessary for a cell to survive.

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.

The equator has light closer to 90 degrees, at the poles the angle is lower than 90 degrees. Use this information and refer to the data from Table B to explain why the tropics (near the equator) are hotter than the arctic region (north/south poles). Be sure to include data from Table B in your answer.
Answers
The temperature at tropic region is warmer than the polar temperatures due to angle of the sun.
The tropics which is located near the equator are hotter than the arctic region i.e. north and south poles because the sunlight falls directly on the tropic regions at 90 degrees while on the other hand, the sunlight falls on the poles not directly and form angle lower than 90 degrees.
The amount of solar energy in a given area is greater at the equator and tropic regions than in an equal area at the poles so that's why the temperature at tropic region is warmer than the polar temperatures.
