Mendel was able to attribute the variation observed in the offspring of his experiment to the controlled fertilization process.
Mendel was able to control pollination and, thus, the fertilization process in the pea plants used for his experiment.
Mendel was able to effectively predict the outcome with self-pollination or cross-pollination with different results coming from each. Thus, he logically concluded that the variation observed in the offspring of his crosses is due to the fact that he controlled the fertilization process.

A scientist performs a series of mutation screens to look for mutations that reduce ATP production. One of the mutants, compared to a wild-type cell, has reduced levels of ATP and NADH and increased levels of FAD and pyruvate. Which hypothesis best fits these observations?
The hypothesis that best fits the observation that one of the mutants has reduced levels of ATP and NADH and increased levels of FAD and pyruvate is that the mutation is disrupting the citric acid cycle (Option 3).
What is the citric acid cycle?The citric acid cycle, also known as the Krebs cycle, is the second step of cellular respiration which is required to generate ATP through the oxidation of pyruvate.
The reduced form of Nicotinamide adenine dinucleotide (NADH) produced during the citric acid cycle is then used in oxidative phosphorylation (the third step of cellular respiration) in order to generate more ATP.
Therefore, with this data, we can see that the citric acid cycle generates the reduced form of Nicotinamide adenine dinucleotide (NADH) and thus increases the production of ATP, thereby a mutation in an enzyme that works in this pathway may also hamper the proportion of ATP.

-Replacement Of Damaged Lungs
-DNA Replication
-Cellular Death
-Uncontrolled Cell Division
Answer:
Uncontrolled cell division
(and I think that HIV/AIDS Does the opposite; slows cell division)
Answer:
uncontrolled cell division
Explanation:
Cancer cells are cells gone wrong — in other words, they no longer respond to many of the signals that control cellular growth and death. Cancer cells originate within tissues and, as they grow and divide, they diverge ever further from normalcy. Over time, these cells become increasingly resistant to the controls that maintain normal tissue — and as a result, they divide more rapidly than their progenitors and become less dependent on signals from other cells. Cancer cells even evade programmed cell death, despite the fact that their multiple abnormalities would normally make them prime targets for apoptosis. In the late stages of cancer, cells break through normal tissue boundaries and metastasize (spread) to new sites in the body.
receptors for neurotransmitters are of primary functional importance in assuring one-way synaptic transmission because they are mostly found on the _____.
Answer:
The axonal membrane (place as brainliest so others know its correct)
Receptors for neurotransmitters are of primary functional importance in assuring one-way synaptic transmission because they are mostly found on the Axonal membrane.
What are Neurotransmitters?Neurotransmitters may be defined as the type of chemical substances that are correspondingly liberated at the end of a nerve fiber by the arrival of a nerve impulse and, by diffusing across the synapse or junction. They are released in the location known as the synaptic cleft.
The receptors of these neurotransmitters are present in the plasma membrane of postsynaptic cells which selectively bind the transmitter. They are integral membrane glycoproteins with multiple transmembrane segments.
Some examples of neurotransmitters may include serotonin, GABA, dopamine, acetylcholine, etc.

Compare 41 Calories to 410 kcal (1 kcal = 1,000 calories). (1 point)
O 41 Calories is greater than 410 kcal
O 41 Calories is equal to 410 kcal
41 Calories is less than 410 kcal
It is not possible to compare these two values
From the calculation, we can deduce that 41 Calories is less than 410 kcal.
Given the following data:
Energy in calories = 41 CaloriesEnergy in kcal = 410 kcalTo compare 41 Calories to 410 kcal, we would simply convert the given values to the same base values:
Hence, we would make Calories the base value by converting the value in kcal to Calories as follows:
Conversion:
1000 Calories = 1 kcal
41 Calories = X kcal
Cross-multiplying, we have:
[tex]1000X =41\\\\X=\frac{41}{1000}[/tex]
X = 0.041 kcal.
From the calculation, we can deduce that 41 Calories is less than 410 kcal.

Without land regulations to protect rainforests, and continues to be destroyed using slash and burn methods Which environmental impact of rainforest deforestation makes rainforest species less resilient to
change?
Increased fire and drought
Increased pollution
Displaced inbes
Habitat fragmentation
Answer:
Increased pollution is your answer!
Explanation:
Increased pollution is your answer because:
1. ⇒ Burning of mostly anything creats, and all the materials in the forest are one of those materials that will create smoke. And smoke is made out of carbon dioxide, and other poisonous gases that are very bad for our atmosphere.
2. ⇒ The damage from the fire will also cause a lot of damage to the trees and plants. That is very bad because trees are very important for our environment, in their leaves, they have a chemical called chlorophyll, this chlorophyll absorbs sunlight and turns it into oxygen. Not only sunlight is needed, there is also, water, nutrients needed.

Which statement correctly describes mitotic cell division?
Answer:
Explanation:
“Although part of your question is missing, you might be referring to this full question:
Which of the following correctly describes how mitosis and meiosis are similar?
A. Sister chromatids segregate to opposite poles of the cell during both mitosis and meiosis.
B. Crossing over occurs between homologous chromatids during both mitosis and meiosis.
C. Both mitosis and meiosis produce diploid daughter cells.
D. Both mitosis and meiosis produce genetically identical daughter cells.”
The statement that correctly describes how mitosis and meiosis are similar is “Sister chromatids segregate to opposite poles of the cell during both mitosis and meiosis”.
Mitosis and Meiosis both are classified under cell division that tends to take place in humans and certain other animals. Both Mitosis and Meiosis have both differences and similarities in the way they result in new cells with varying goals and slightly different outcomes. Some of the similarities between meiosis and mitosis are:
During both mitosis and meiosis, cells must duplicate their DNA and pull them apart into 2 sets and further place the sets on each end of itself and then divide down the middle part
Both meiosis and mitosis results in fresh new cells depending on the genes of their parent cells
Thus, we can conclude that the statement that correctly describes how mitosis and meiosis are similar is “Sister chromatids segregate to opposite poles of the cell during both mitosis and meiosis”. Hence, option A is the correct answer.

Explanation:
active transport moves mineral ions into root hair cells through cell membrane proteins. Explain how protein molecules move ions across a membrane during this process. (3marks)
Explanation:
Small and nonpolar (hydrophobic) molecules can freely pass through the membrane, but charged ions and large molecules such as proteins and sugars are barred passage.
Nonpolar and small polar molecules can pass through the cell membrane, so they diffuse across it in response to concentration gradients.

Biodegradation of preozonated 4-CPh by a mixed microbial consortium at 30 h (empty square), 62 h (empty inverted triangle), 102 h (empty circle) of culture, respectively.

autonomic reflexes enable the ans to control what kinds of visceral functions? check all that apply.
Given what we know about the Autonomic Nervous System we can confirm that autonomic reflexes enable the ANS to control functions such as heart rate, urination, and breathing rates.
These are among the many visceral functions that the Autonomic Nervous System controls. As per the pattern that is being established, we can conclude that the Autonomic Nervous System functions at a subconscious level, controlling the visceral functions that do not require conscious thought.
Despite this, some organs can also be controlled consciously, such as the lungs and bladder. Other visceral functions such as heart rate, digestion, and even ocular responses, are not able to be controlled consciously.
