John Needham, Louis Pasteur, and other scientists all performed experiments to disprove ______.
a) spontaneous generation
b) evolution
c) Koch's postulates
d) binomial nomenclature

Answers

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.

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

Answers

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.

explain how thermal pollution can impact on the quality of water biodiversity​

Answers

Answer: Biodiversity can be decreased as a result. High temperature limits oxygen dispersion into deeper waters, contributing to anaerobic conditions. This can lead to increased bacteria levels when there is ample food supply. Many aquatic species will fail to reproduce at elevated temperatures. I hope this helps :)
The primary effects of thermal pollution are direct thermal shock , changes in dissolved oxygen, and the redistribution of organisms in the local community. ... Cold water contains more oxygen than hot water so increases in temperature also decrease the oxygen-carrying capacity of water.

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

Answers

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.

g Two linked genes, (A) and (B), are separated by 18 centiMorgans. A man with genotype Aa Bb marries a woman who is aa bb. The man's father was AA BB. What is the probability that their first child will both be ab/ab

Answers

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 ⇒ aabb

The 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%

Ab 9%

aB 9%

Cross: man x woman

Parental)          AaBb           x          aabb

Gametes) AB, Ab, aB, ab        ab, ab, ab, ab

Punnett square)     AB ( 41%)       Ab (9%)      aB (9%)       ab (41%)

                   ab      AaBb               Aabb          aaBb            aabb

                   ab      AaBb               Aabb          aaBb            aabb

F1) 41% of the progeny is expected to be AaBb

Which process is characterized by the movement of particles from an area of high concentration to an area of low concentration across the plasma membrane without the use of energy?

1) hypertonic transport
2) active transport
3) passive transport
4) dynamic equilibrium

Answers

Answer:

3) passive transport

Explanation:

Passive transport is a type of cellular transport that does not require the use of energy to move substances (i.e., ions and molecules) across biological membranes. Passive transport uses concentration gradients to move substances across cell membranes, thereby transporting them from regions of high concentration to regions of low concentration. Passive transport can be divided into 1-osmosis (i.e., movement of solvents), 2-diffusion (i.e., movement of solutes), and 3-facilitated diffusion (i.e., movement of molecules with help of protein channels or carriers), and 4-filtration (i.e., movement of water by using a pressure gradient).

Answer: moves particles from on area of low concentration to an area of high concentration

Explanation: Active transport differs from passive transport because active transport

can only move particles into the cell.

does not require energy to transport particles.

moves particles from an area of low concentration to an area of high concentration.

depends on the random movements of particles to carry them across the membrane.

How does your model support the claim that
the Northern and Southern Hemispheres
have different seasons?

Answers

Answer:

Due to presence on opposite side of the globe.

Explanation:

My model support the claim that  the Northern and Southern Hemispheres  have different seasons due to present on different location on the globe. The seasons in the Northern Hemisphere are different and opposite of those in the Southern Hemisphere. Seasons occur because Earth is tilted on its axis. This tilting causes summer in one location whereas winter in other location. The Earth's tilt causes the Southern Hemisphere to lean towards the Sun during summer season of Southern Hemisphere while on the other hand, it is winter season in the Northern Hemisphere which leans away from the Sun.
