John Needham, Louis Pasteur, and other scientists all performed experiments to disprove ______.
a) spontaneous generation
b) evolution
c) Koch's postulates
d) binomial nomenclature
Answer:
A) spontaneous generation
Explanation:
Spontaneous Generation theory stated that living organisms could be spontaneously generated from non-living matter. Francesco Redi conducted an experiment similar to the one Louis Pasteur would do nearly 200 years later. The 17th-century Italian developed a spontaneous generation experiment that showed that maggots do not spontaneously emerge from decaying meat.
MARK THIS ANSWER BRAINLIEST PLEASE ❤️
The theory of spontaneous generation is an experiment that tries to prove the possibilities that living organisms can be produced from non-living origins.
This experiment was first done by Francesco Redi in 1668. However, several scientists such as John Needham, Louis Pasteur, John Tyndall amongst other scientist tried to disprove the theory of spontaneous generation.
The theory was later disproved by Louis Pasteur and John Tyndall in the mid-19th century.

Explanation:
You observe every fall that the trees in the forest lose their leaves, but by the following fall, the leaves have disappeared. The most accurate explanation for this observation would be:
The tree creates a layer known as the abscission layer, which prevents nutrients and water from reaching the tree and inhibits the growth of the leaves. Hormones in the trees cause the process of abscission.
What is abscission layer?Tiny tubules in the abscission layer are responsible for carrying carbohydrates back into the tree and delivering water to the leaf, flower, or fruit.
The amount of nutrients and water that pass through the tubes is decreased in the autumn because cells in the abscission start to expand and exude a waxy substance.
Abscission of leaves, which takes place in the fall, is the natural loss of an old leaf at the base of the petiole. Many physical and biochemical changes occur during leaf abscission, most of which are controlled by plant hormones.
Therefore, every fall that the trees in the forest lose their leaves.

This is the type of succession that
occurs when all of the usable soil
has been destroyed in an
ecosystem.
A seccession
B primary
C Secondary
C. Secondary Succession
The process of an ecosystem returning to its stable form after a disaster is known as secondary succession.
This happens faster than primary succession because the soil is already formed and nutrients are more available at the beginning of the process.
Hope it helps you! ＼(^ᴥ^)／
Secondary is the type of succession that occurs when all of the usable soil has been destroyed in an ecosystem.
What is a succession?Succession is the process of change and development that occurs in an ecosystem over time. It refers to the gradual replacement of one community of plants and animals with another, as each community modifies the physical and biological environment in which it lives. There are two main types of succession: primary succession and secondary succession.
Primary succession occurs in an ecosystem that has no soil or vegetation, such as on newly formed volcanic islands or in areas where glaciers have retreated. During primary succession, the ecosystem must develop from scratch, with the creation of new soil and the establishment of new plant and animal communities. This process can take a significant amount of time.
Secondary succession occurs when all of the usable soil has been destroyed in an ecosystem. This type of succession can occur after a natural disaster, such as a fire or a flood, or after human activity, such as logging or farming. During secondary succession, the ecosystem must rebuild itself from scratch, with new soil being created and new plant and animal communities establishing themselves. This process can also take a significant amount of time, depending on the severity of the disturbance and the conditions of the ecosystem.

A white blood cell (WBC) encounters bacteria in a scrape on the knee of a child who has fallen off of his bicycle. The WBC’s job is to take the bacteria inside of itself and destroy the bacteria. If the bacteria cannot be moved across the WBC membrane, how will the WBC most likely take it in?
Answer:
The correct answer is - phagocytosis.
Explanation:
Phagocytosis is a type of endocytosis that also engulfs the solid material including microbial pathogens like bacteria and others. In immunity response macrophages, neutrophils and. immature dendritic cells are white blood cells that perform the phagocytosis process to kill the microbes and antigens.
Phagocytosis ingests and digest pathogens and develops an adaptive immune response an essential part of the innate immune system. WBC will most likely take it in through phagocytosis in the given case.

D) A population of deer show an increase in antler size over time, which allows them to obtain more mates
during mating season
Answer:
D) A population of deer show an increase in antler size over time, which allows them to obtain more mates during mating season
Based on Darwin's ideas, a population of deer show an increase in antler size over time, which allows them to obtain more mates during mating season (Option D).
What is evolution?According to Darwin, evolution can be defined as descendence with modification, which mainly occurs via natural selection.
Natural selection can be defined as the differential survival and reproduction of the fittest organisms.In this case, intraspecific competition favors deers more adapted to reproduce in the population.In conclusion, based on Darwin's ideas, a population of deer show an increase in antler size over time, which allows them to obtain more mates during mating season (Option D).

Answer:
The probability that their first child will both be ab/ab = 41%.
Explanation:
Available data:
Two linked genes (A) and (B) ⇒ 18 centiMorgans apartMan ⇒ Aa BbMan´s father ⇒ AA BBWoman ⇒ aabbThe recombination frequency is given by the distance between genes. We have to know that 1% of recombinations = 1 map unit = 1cm.
Recombination frequency = 0.18
Man: AaBb
Gametes) AB Parental
ab Parental
Ab Recombinant
aB recombinant
18 centi morgan = 18 % of recombination in total
= % aB + % Ab
= 9% aB + 9% Ab
100% - 18% = 82% of parental in total
= % of AB + % ab
= 41% AB + 41% ab
The frequency for each gamete is:
AB 41%
ab 41%

Which statement correctly compares mass and weight?
A.Both depend on the force of gravity pulling on an object B.The basic unit of both is the kilogram C.Both mass and weight ofan object would be less on the moon than on Earth D.Weight varies with location, but mass does not vary
Answer:
D. Weight varies with location, but mass does not vary
Explanation:
Weight can be defined as the force acting on a body or an object as a result of gravity.
Mathematically, the weight of an object is given by the formula;
[tex] Weight = mg [/tex]
Where;
m is the mass of the object.g is the acceleration due to gravity.Mass can be defined as a measure of the amount of matter an object or a body comprises of. The standard unit of measurement of the mass of an object or a body is kilograms.
Irrespective of the location of an object or a body at a given moment in time, the mass (amount of matter that they're made up of) is constant. This ultimately implies that, whether you're in the moon, space, earth or any other place, your mass remains the same (constant).
Hence, the statement that correctly compares mass and weight is that, weight varies with location, but mass does not vary. This is simply because acceleration due to gravity changes with location i.e its value varies with the planets.
