What is Evolution? best answer will get a brainliest!
Answer
Evolution is basically just the process in which different types of organisms have devoloped.
Easier way of saying it:
The gradual development of something
usually from something simple to something complex.
Have a great day :)
Answer:
Evolution is the gradual change of characteristics and traits, that occurs within a species, over many generations.
Explanation:
Due to natural selection, some genes of a species can be passed on to their offspring, to increase chances of survival. This is because these new traits are enabling, the organisms who have them, to survive longer then the ones who don't, thus allowing them to procreate and have more offspring, who share that same trait.
This process can occur over several generations, and in turn, can really change a species.

If a population pyramid is shaped like a true pyramid, what can we determine about that population's growth?
Answer:
A population pyramid does not provide information about the actual population in terms of numbers. Another way to think about it is that the bottom of the pyramid is bigger than the top, indicating that a greater proportion of the population is in their reproductive years or has not yet reached reproductive age. As a consequence, there is a great deal of room for expansion.
Explanation:
Hope it helps:)
If a population pyramid is shaped like a true pyramid, with a wide base and gradually narrowing towards the top, it indicates a population with a high birth rate, a decreasing death rate, and a potential for rapid population growth.
A wide base of the pyramid suggests a larger proportion of young individuals, typically representing a high birth rate. This means that a significant number of babies are being born within the population.
As the pyramid narrows towards the top, it indicates a smaller proportion of elderly individuals. This suggests a decreasing death rate, meaning that more people are surviving into older age due to improvements in healthcare, nutrition, and living conditions.
The combination of a high birth rate and a decreasing death rate creates a population structure conducive to rapid growth. With a larger number of young individuals entering reproductive age in the future, the potential for continued high birth rates exists.

What term is used to describe the premise that increased ventricular filling improves contractile force of the heart as a result of greater stretch of cardiac fibers
Frank – Starling law is used to describe the premise that increased ventricular filling improves contractile force of the heart as a result of greater stretch of cardiac fibers.
According to the Frank – Starling law, the more the heart muscle is stretched during filling, the greater the contractile force and the greater the amount of blood pumped into the aorta are, as well as the ejection pressure.
This is because there is a relationship between cardiac fiber length (equivalent to end-diastolic volume) and force of contraction (equivalent to stroke volume).When an extra amount of blood reaches the heart, the heart muscle stretches more and is able to contract with greater force.Therefore, we can conclude that Frank – Starling law is used to describe the premise that increased ventricular filling improves contractile force of the heart as a result of greater stretch of cardiac fibers.

The enzyme machinery responsible for mismatch repair must be able to distinguish between the template strand and a newly synthesized strand. How is that achieved in a bacterial cell, such as E. coli
Answer: For a short period of time after replication, the sequence GATC is methylated at the A only on the template strand.
In recently manufactured DNA, a mismatch has been found. The template (old) strand's T is coupled with a G in the new strand.
What effects of mismatch repair in enzyme machinery?DNA damage causes the mismatch repair enzyme MLH1 to become active. However, MLH1 expression appears to be connected to apoptotic signaling.
As well as being necessary for damage repair, When it is activated, activities that result in planned cell death are triggered.
A region of DNA containing the mismatched nucleotide and its neighbors is removed, and the new DNA strand is cut. A DNA polymerase substitutes the missing nucleotides for the missing patch.
The mismatch repair machinery separates the newly synthesized strand from the template to start the repair process (parental).
Therefore, a short period of time after replication, the sequence GATC is methylated at the A only on the template strand.

The process by which water and some solutes in the blood plasma pass from the glomerular capillaries into the capsular space is called glomerular __________.
Answer:
Glomerular Filtration
Explanation:
This is a process of bulk flow driven by the hydrostatic pressure of the blood. Small molecules pass rapidly through the filtration membrane, while large proteins and blood cellsare kept out of the capsular space. If the filtration membrane is damaged, proteins will leak through and end up in the urine. Hope this helps :)
In which order do the events of antidiuretic hormone (ADH) secretion stimulated by plasma osmolarity occur
The order in which the ADH stimulated by plasma osmolarity occurs is:
an increase in plasma osmolarity, activation of osmoreceptor, release of ADH, reabsorption of water.
The antidiuretic hormone (ADH) is responsible for the homeostatic valance and increase in blood's volume. The activation of this hormone and how it works is as follows:
There is a low concentration of water in the body, which decreases the extracellular fluid.The decrease in the extracellular fluid results in a reduction of the plasma osmolarity, in other words, the blood volume is reduced.As a consequence, the osmoreceptors in the hypothalamus, kidneys, and carotid detect the high concentration of solutes. The hypothalamus releases ADH.The hormone travels through the blood to the kidney. There, it stimulates the reabsorption of water and reduces urine production.The body is hydrated again.
To sum up, the body detects a high concentration of solutes due to a loss of water. Then it releases ADH; as a consequence, the kidneys reabsorb water till the osmolarity decreases.

If a haploid cell has 16 chromosomes in its nucleus, how many would be present in the diploid state? View Available Hint(s) for Part A 4 8 32 64
Answer:
If a haploid cell has 16 chromosomes in its nucleus, how many would be present in the diploid state? A. 4. B. 8. C. 32. D. 64. C.
Explanation:
If the haploid cell has 16 chromosomes in its nucleus, then it has 32 chromosomes in the diploid state. The option saying "32" is correct for this condition.
What is a chromosome?
The chromosomes are present in the nucleus of the eukaryotic cell, and their number varies from species to species. One species may get 4 chromosomes while others, like humans, have 46 chromosomes.
The haploid cells are formed by the process of meiosis, where the cell gets half of its genetic content from the parent cell. If the haploid cell gets 16 chromosomes, then the parent cell, which is the diploid cell, gets 32 chromosomes. In the parent cell, there are two copies of a gene, one from the paternal side and one from the maternal side. The same genetic content is transferred to the daughter cells during mitotic division.
Hence, as a haploid cell is formed with 16 chromosomes, the diploid cell has 32 chromosomes.

Activation of muscarinic receptors will 1. cause skeletal muscle contraction 2. increase heart rate 3. causes secretion of digestive enzymes
Given what we know about muscarinic receptors, we can confirm that the activation of these receptors will result in an increase in heart rate.
Muscarinic receptors are also often referred to as acetylcholine receptors. These are membrane receptors that tend to form G protein-coupled complexes. Though the activation of these receptors will not increase the heart rate in a direct fashion, it will do so indirectly through its interaction with acetylcholine molecules.
Acetylcholine is a very common molecule in the human body. This molecule plays the role of a neurotransmitter, meaning its job is to send signals to other cells, like in this case muscle cells in the heart.
This organic chemical signals the heart muscles to contract at slower speeds, thus decreasing heart rate. The activation of Muscarinic receptors inhibits these Acetylcholine molecules, stopping their signal and causing the heart rate to increase.

Which method do you think best represents energy flow through ecosystems? Why?
this needs to be a paragraph or two :)
Answer:
The circle of life, in which energy flows into the world from the sun, giving plants that energy to live. All of the organisms in an ecosystem are chemical machines driven by the energy captured in photosynthesis. The organisms that first capture energy, the producers, include plants, some kinds of bacteria, and algae. All other organisms in an ecosystem are consumers.
The plants energy will then be transferred to a small animal, most likely a rabbit or maybe a mouse; depending on the plant. The small animal will then be eaten by a bigger more dominating animal like an eagle or a snake. It just goes on and on. The eagle or the snake will get eaten by a bigger animal or will decompose into the earth giving the soil and plants around it that same energy.

The method that best represents the flow of energy through the ecosystem is known as the pyramid of energy.
What is an Ecosystem?An ecosystem may be defined as a type of place or an area where individuals of different species live together and interact with one another for the purpose of food, shelter, and space.
As well all know that the pyramid of energy is always upright in all sorts of ecosystems, whether it is grasslands or aquatic. This is because the energy flow from one trophic level is only 10% that has to be transferred to the next trophic level in all ecosystems.
This system of energy movement is so efficient that even a little energy can not be wasted. It all gets consumed by the next trophic level.
Therefore, the pyramid of energy is the method that best represents the flow of energy through the ecosystem.

3. In the 1660s, Flemish physician Jan van Helmont grew a small willow tree in a pot of soil. He
added only water to the pot. At the end of five years, he found that the tree had gained 75
kilograms, but there was very little change in the mass of the soil. Van Helmont concluded that
the plant gained weight directly from the water. We now know that this conclusion is only
partially correct because, in addition to water, photosynthesis also requires
(1) oxygen from the atmosphere
(2) proteins from animal prey
(3) carbon dioxide from the atmosphere
(4) carbohydrates from the soil
The conclusion that can be drawn by Flemish physician Jan van Helmont is partially correct because, in addition to water, photosynthesis also requires carbon dioxide from the atmosphere. Thus, the correct option for this question is C.
What is Photosynthesis?Photosynthesis may be defined as a process through which green plants and some photosynthetic algae synthesize their own food in the form of glucose with the help of carbon dioxide and water in the presence of sunlight.
The complete reaction of photosynthesis is as follows:
[tex]6CO_2+12H_2O[/tex] → [tex]C_6H_1_2O_6+6O_2+6H_2O.[/tex]With the help of this reaction, it is identified that carbon dioxide and water act as reactants in photosynthesis while glucose and oxygen are the products. Hence, along with water, carbon dioxide must also be required in order to accomplish the process of photosynthesis.
Therefore, the correct option for this question is C.
