A. Origin of Life- Scientists Hypotheses Disproving Spontaneous Generation (Word Bank: air, sealed, open, bacteria, gauze, spontaneously) Through the early 1800s, people believed organisms could ________________ develop, an idea known as spontaneous generation. In 1668, many believed maggots were spontaneous generated from rotting meat. Francis Redi’s experiment disproved this by experimenting with meat in open_jars, tightly snealed_jars and jars covered with cloth netting. It was also believed that bacteria spontaneously generated in broth. Lazzaro Spallanzani removed the _________ from a flask, __________ the broth and sealed the flask. No bacteria generated without exposure to the air. Some people still supported spontaneous generation but thought that air was a ________ force, necessary for it to occur. In 1859, Louis Pasteur completely disproved spontaneous generation by using a special flask that allow ______________ in but captured bacteria before it could get to the broth. No _________________ grew in the flask after boiling = no spontaneous generation. 2. First Life (Word Bank: eukaryotes, prokaryotic, variety, self-replicating, organic, photosynthesis, oxygen) Earth’s atmosphere had to be very hot and with little oxygen for the first ________________ molecules to first form. Organic molecules clumped together for form ______________________ structures that later evolved into cells. __________________________ cells were the first to evolve. When cells gained the ability to do ___________________________, they used up carbon dioxide and put more __________________ into the atmosphere.

At the end of the summer, the normal plants had grown more than those with variegated leaves. All the plants had been grown in the same conditions. Explain why plants with normal leaves grow more than plants with variegated leaves.
Answer:
Pigment
Explanation:
The normal leaves contain more of a green pigment suggesting more chlorophyll present in the plant. This increases the rate of photosynthesis meaning the plant can grow faster. Variegated leaves have variation of colours some are not green meaning they grow slower.
Hope it helped
Plants with normal leaves grow more than plants with variegated leaves because variegated leaves have reduced chlorophyll content, impacting photosynthesis and overall growth.
What is variegated leaves?Variegated leaves refer to leaves that display a pattern of different colors or shades, typically characterized by patches, stripes, or streaks of contrasting pigmentation. This variation in coloration is a result of genetic mutations or changes in chloroplast distribution within leaf cells.
In variegated leaves, the color variation is caused by differences in chlorophyll content, which is responsible for the green color in leaves. The areas with reduced chlorophyll may appear white, yellow, cream, or other colors depending on the pigments present. This variation can be stable throughout the plant's life or occur only in specific conditions or stages of growth.
Variegated leaves can be found in a variety of plant species, both in the wild and in cultivated plants. They are often valued for their ornamental appeal and can add visual interest and uniqueness to gardens, landscapes, and indoor spaces.

Darwin studied actual birds on the Galapagos Islands instead of using a simulation, as you did in this lab. Studying natural selection in the field can be challenging. List at least three possible challenges Darwin might have faced
Answer:
Traits other than beak type might affect natural selection.
It could take many generations to observe adaptions to a population.
The environment may be complex and hard to study.
Changes in the environment may occur faster or slower than changes to the birds
The birds may be interdependent with other organisms that may change, too.
Explanation:
Answer:
Traits other than the form of beak may impact natural selection. Adjustments to a society could take several generations to observe. It can be complicated and difficult to research the climate. Environmental changes can occur faster or slower than changes in birds. Birds can be interdependent with other species, which can also alter.
For how many hours could an average person be sustained by the body's stored glycogen under resting conditions?
Answer:
The correct answer to the following question will be "12-14 hours".
Explanation:
Glycogen has always been processed throughout the skeleton's liver as well as muscle cells, which lead to the generation of power generation whenever the body can handle it. This seems to be a polyacrylamide, which represents the physical species as a type of power. This could be processed for 12-14 hours in repose throughout the living organism (human body).Iodine-131, a beta emitter, is one such product of nuclear fission, extremely dangerous because it is typically produced in huge quantities and because it is incorporated in the human body in the thyroid gland. The half-life of 1311 is 8.04 days. What fraction (expressed as a decimal number) of the 1311 produced in a nuclear accident would remain after 60.0 days?
Answer:
0.00568
Explanation:
Recall that the fraction of radioactive material left after a time (t) is obtained from the formula;
N/No = (1/2)^t/t1/2
Where;
N= mass of radioactive material left after a time t
No= mass of radioactive material initially present
t= time taken for N mass of radioactive substance to remain = 60.0 days
t1/2= half-life of the radioactive substance= 8.04 days
Note that the required fraction is N/No, hence;
N/No= (1/2)^60.0/8.04
N/No= (1/2)^7.46
N/No = 0.00568
Which statement about the moths does the data support ?
Answer:
C. The dark colored moths chose to mutate to become adapted to dark-colored trees.
Explanation:
In the given data, the population of light colored moths decreases in dark colored tress while the population of dark colored moth increases in dark-colored trees.
The concept is based on natural selection in which dark color moths undergo mutation to adapt to dark colored trees. This mutation provide camouflage to dark colored moths and increases their population in comparison to light colored moths.

What forms of subtle implicit discrimination do you recognize around you? Explain
Answer:
Examples include:
1. A female employee not given certain rigorous projects which she is interested in. This leaves her wondering if her gender could be the cause of the exemption.
2. A Chinese employee who was exempted from a get together at his workplace (which is dominated with Africans) and he wonders if it was a result of his nationality.
Explanation:
Discrimination is the act of segregating or exhibiting prejudice on a particular set of people for reasons such as race, gender, age, or sex. Discrimination could be overt or subtle. Overt discrimination is frontal and more recognizable when compared to subtle discrimination which is more blurry and difficult to recognize.
For example, if a prospective employer expressly says that female employees are not needed for a role, it is quite easy to recognize this as a form of discrimination. This illustrates overt discrimination. But then subtle implicit discrimination are more difficult to recognize. They leave the victim wondering if the act was actually discriminatory and it is quite harder to lodge legal complaints about these types of discrimination. Examples are some of these stated above.
Sheryl is observing ovarian slides taken from a female ape. All the cells show crossover chromosomes. What is this stage?
ОА
meiotic prophasel
ОВ.
meiotic prophase II
Ос.
meiotic metaphase
Answer:
meiotic prophasel
Explanation:
Crossing-over is a unique phenomenon that only occurs during meiotic division or gamete formation. It is the process whereby non-sister chromatids of homologous chromosomes exchange a portion of the their chromosome.
Crossing-over occurs specifically in the Prophase 1 stage of meiosis, where homologous chromosomes lie side by side to form a TETRAD structure and exchange their chromosomal segment. Crossing-over aims at promoting genetic diversity among sexually-reproducing organisms.
Therefore, an ovarian slide observed to show crossing-over occurs at the Prophase I stage of meiosis 1.

Which of the following statements is true? Somatic cells are diploid, meaning that they have two copies of the human genome. Somatic cells are haploid, meaning that they have one copy of the human genome. Sperm and egg cells are diploid, meaning that they have two copies of the human genome. Stem cells are haploid, meaning that they have one copy of the human genome.
Answer:
Somatic cells are diploid, meaning that they have two copies of the human genome.
Explanation:
Somatic cells are any of the cells found in the body which are not gametes or germ cells. They are diploid in that they contain two sets of chromosomes, one inherited from each parent.
A germ cell is a cell containing half the number of chromosomes (are haploid) and able to fuse with one from the opposite sex to form a new individual. They undergo the process of mieosis to become haploid cells.
Stem cells are undifferentiated or unspecialized cells with self-renewal capacity. They can divide through mitosis limitlessly to replenish other cell types of multicellular organisms throughout their life. They contain two sets of chromosomes (are diploid) one from each parent. They of two types: embryonic and adult somatic stem cells.
True: Somatic cells are diploid, meaning that they have two copies of the human genome.
False: Somatic cells are haploid, meaning that they have one copy of the human genome.
False: Sperm and egg cells are diploid, meaning that they have two copies of the human genome.
False: Stem cells are haploid, meaning that they have one copy of the human genome.
