Explanation:

The most likely explanation here is that mitochondria was once a prokaryotic organism. The correct option is A.
What is mitochondria?Mitochondria are membrane-bound cell organelles that produce the majority of the chemical energy required to power the cell's biochemical reactions (mitochondrion, singular).
The mitochondrial energy is stored in a small molecule known as adenosine triphosphate (ATP).
Mitochondria are special compartments (organelles) in our cells best known for their role as powerhouses, converting food molecules into ATP, a molecular fuel for the rest of the cell.
Mitochondria and chloroplasts most likely evolved from engulfed prokaryotes that were once self-contained organisms.
At certain point, an aerobic prokaryote was engulfed by a eukaryotic cell, which then formed an endosymbiotic relationship with the host eukaryote, eventually developing into a mitochondrion.
Thus, the correct option is A.

6) In Medieval times a ruler told the peasants that they were free to take anything from the forest that had fallen, branches, trees, leaves etc. But they were not to take any live standing trees. Within a few years the forest was dying. Why
Answer:
Due to lack of nutrients in the soil.
Explanation:
Within a few years the forest was dying because there is no nutrient is present in the soil which can trigger the growth and development of the sol. The fallen parts of trees such as branches, tree and leaves etc are decomposed by decomposers such as bacteria and fungi which turn the fallen materials into nitrogenous materials which can be used by the plant for its growth and development.

Heat Transfer Mechanisms 1.In your own words, using the pennies activity, define the three different heat transfer mechanisms. Your definitions should include:
(i) information about how energy is moving
(ii) what is happening microscopically (that is, at the atomic level)
(iii) what phase(s) of materials is usually involved.
Answer:
The three modes of heat transfer are: 1) Radiation 2) Convection 3) Conduction
Explanation:
RADIATION:
It is the mode of heat transfer which requires no medium because the transfer of energy takes place in the form of electromagnetic radiations. The spectrum of radiations that contribute to the heat transfer via radiation is the wavelength ranging from 0.1 μm to 100 μm.
For example the heat from the sun reaches the earth via radiation that passes through space and then through the atmosphere of the earth.
CONVECTION:
It is the mode of heat transfer that takes place in a fluid matter. The molecules in this case move from one place to another due to the difference in density developed as a result of heat absorption.
Example, the boiling of water. When the water in a utensil is heated, the heat is supplied at the bottom. In such a case the molecules of the water absorb the heat resulting in increased intermolecular spacing and hence the water at the bottom becomes the least dense in the bulk of water mass in the utensil hence rises up at to the free surface of the fluid mass. Then the densest mass of the fluid occupies the bottom space and is heated by the heat source supplied. This chain continues.
CONDUCTION:
This is the process of heat transfer from one molecule to the next neighbouring molecules. The propagation of heat energy occurs in a sequential manner starting from the molecule nearest to the heat source. The microscopic phenomenon happens in the form of lattice vibrations that are responsible for the transfer of heat energy via conduction.
Example, while heating of a pan the base heats up at first being continuously exposed to heat whereas the handle of the pan being far away from the source heats up after a long time.
You have an experience that causes a complex network of neurons to be built in your brain. This network is most likely a _____. (Mark the one best answer.) ❍ a receptive field❍ B disease❍ C memory❍ D motor pathwa
Answer:
a receptive feild
Explanation:
The complex network of neurons built in response to an experience is most likely a memory.
What is neuron?Neurons are specialized cells that are the basic building blocks of the nervous system. They are responsible for receiving, processing, and transmitting information through electrical and chemical signals.
Memories are encoded in the brain by the formation and strengthening of neural connections between neurons, also known as synaptic plasticity.
When we experience something new, this process of synaptic plasticity is triggered and neurons form new connections or strengthen existing ones to encode the information.
Over time, these connections can become consolidated into long-term memory.
Therefore, when a person has an experience that causes a complex network of neurons to be built in their brain, it is most likely a memory.

DDT is an insecticide that accumulates in the fatty tissues of animals whose concentration increases with each link of the food chain. Which group of organisms is most likely to accumulate the highest concentration of DDT?
The question is incomplete, the complete question is shown in the image attached
Answer:
D
Explanation:
Pollutants tend to an increase in concentration in the fatty tissues of animals compared to the concentration of the same pollutant in the environment.
Also, tend to increase in the fatty tissues of organisms at each trophic level.
Hence, as a result of this, the highest concentration of the insecticide is accumulated by the organisms at the highest level of the food chain. So, the tertiary consumers accumulate the highest concentration of the insecticide.

A scientist is researching oil content of seeds from a new plant species named R. artificial. The average oil content from plants in her lab population is 52%, and she has determined the narrow sense heritability (h^2) is 0.60. If she randomly mates individuals with 70%, 71%, 72%, 73%, and 74% seed oil content what is the expected response to selection (R)?
Answer:
The correct answer is - 12%
Explanation:
Given:
Mean of the population - 0.52
Narrow sense heritability or h^2 - 0.6
The expected response of selection or R = ?
Solution:
The average oil content in the selected individuals - 0.7, 0.71, 0.72, 0.73, 0.74
And, the mean of these selected individuals = (0.7 + 0.71 + 0.72 + 0.73 + 0.74) / 5
= 0.72
Formula:
S = Average of selected individuals - Average of population
= 0.72 - 0.52
= 0.20
R = h^2 x S
R = 0.6 x 0.2
= 0.12
= 12%
Thus, the correct answer is - 12%

Chris is studying oxidation and reduction reactions. Which of the following could she use as an example of an oxidation reaction?
Answer:
This question lacks options, the options are as follows:
A. formation of ATP from glucose during respiration
B. formation of carbohydrates from carbon dioxide during photosynthesis
C. formation of oxygen from water molecules during photosynthesis
The answer is A. formation of ATP from glucose during respiration
Explanation:
Oxidation reaction is a type of reaction that involves the loss of electrons (e-) by a compound or molecule. The compound/molecule that loses the electron is said to be OXIDIZED.
According to this question, Chris is studying oxidation and reduction reactions (redox). An example of oxidation reaction she could use is FORMATION OF ATP FROM GLUCOSE DURING RESPIRATION. Glucose (C6H12O6) undergoes series of oxidation reactions in glycolysis, Krebs cycle and ETC, as it loses electrons to eventually produce energy (ATP).
