Explanation:
Evaluate the neighbor's arguments in the following scenario. Are there facts he is overlooking?
An elderly neighbor says today's girls are less mature than they used to be. He says it used to be that by the time a girl had a mature body, she had
a mature brain to go along with it. The neighbor argues that it all comes down to bad parenting and too much television.
Answer:
He is trying to explain that girls in his day had more respect for their self than they do not
Explanation:
They copy what they see on tv, school,and friends
Answer:
First of all, every child develops and matures on their own pace (within a certain range) and we can't compare one person to another. Secondly, in general, girls are reaching puberty earlier than they used to, which may stem from nutritional or environmental influences. For example, in 1900, the average age of puberty for girls was fifteen; today, it is twelve and a half. Moreover, attaining puberty or having a mature body doesn't result in a mature or fully developed brain. The brain continues to develops on its own pace from the rest of the body, until into adulthood to the age of twenty-five.

A scientist could best determine which ion (F-, Cl-, Br-, or I-) produced the greatest electrical potential in the Experiment by comparing the electrical potential that develops between ice and:
a solution of each sodium salt at the same concentration.
a single sodium salt solution at different concentrations.
a single sodium salt solution at different temperatures.
droplets of sodium salt solutions at different collision rates.
Answer:
a solution of each sodium salt at the same concentration
Explanation:
If a scientist wishes to study the electrical potential that develops between ice and the sodium salts solution of the ions (F-, Cl-, Br-, or I-) in order to determine which ion produced the greatest electrical potential; he must compare the electrical potential that develops between ice and a solution of each sodium salt at the same concentration.
This means that conclusions can not be reached unless the sodium salt of each ion at the same concentration is compared so as to ensure consistence in the results of the study.

What would happen if cytokinesis did not work properly?
1) DNA replication would not occur
2) A cell would have a nucleus with too many chromosomes
3) A cell would have two nuclei
4) New daughter cells would not have enough organelles or would be missing organelles
5) a cell would be smaller in size
Answer:
If cytokinesis did not occur during mitosis the cytoplasm wouldn't be divided and there wouldn't be two identical daughter cells as a result. so the cell would remain to be at rest not being able to separate into two individual cells

Look at the food web. In your response, answer the following questions
correctly for full credit: a) Identify the producers, primary consumers, and
secondary consumers in the ecosystem. b) What would happen if all the
hawks in this ecosystem were to die from an illness? c) Why would you
expect there to be fewer foxes than caterpillars in this ecosystem? d)
Which organism would have the smallest population? (8 points)
Answer:
A) Grass and ferns are the producer. Rabbits, Grasshoppers and caterpillars are the primary consumers. The robin, foxes and hawks are the secondary consumers.
B) If the hawks died, the rabbits and foxes would over-populate the area. The rabbits would over graze the ferns and make it harder for the caterpillars to feed. The foxes would over graze on the robins, potentially wiping them out. This would allow the grasshopper to grow out-of-control leading to the loss of the second food source for the caterpillars. Eventually, the ecosystem would crash.
C) The higher up the food pyramid you go, the smaller the population has to be. Foxes are higher up than caterpillars so they have to have a smaller population.
D) The hawk has to be the smallest population.

Quién propuso el primer mecanismo de herencia a partir de la observación y la experimentación con plantas?
Answer:
Gregor Mendel
Explanation:
Gregor Mendel fue un naturalista, biogista y matemático que demostró por primera vez los principios de la herencia utilizando su trabajo sobre las plantas de guisantes.
Publicó su trabajo en "Experiments in Plant Hybridization" en el año 1866. Al controlar la polinización, Mendel pudo cruzar plantas de guisantes con diferentes formas de rasgos. En el primer conjunto de experimentos de Mendel, experimentó con solo una característica a la vez. Los resultados de este conjunto de experimentos llevaron a la primera ley de herencia de Mendel llamada ley de segregación (Bio Libretexts).

During cellular respiration, glucose molecules undergo a series of reactions. This process results in the formation of up to 38 molecules of high-energy ATP per each molecule of glucose. Which is the source of the energy stored in these ATP molecules?
chemical energy originally stored in the glucose molecule
potential energy from the difference in the concentration gradients of the cell
kinetic energy generated by the chemical reactions
electric current created during the destruction of electrons in the glucose
Answer:
1.Sugar bonds
2.Transport proteins
3. Digestion
4. Oxidation
explanation
Chemical energy is stored in the bonds of sugar.
The concentration gradient of a substance across the membrane represents potential energy bcz it drives diffusion.Transport proteins aids the diffusion.
Digestion converts chemical energy into kinetic energy used by cells.
When the electrons are destroyed in the glucose,Energy contained in the bonds is released in small bursts,some of it is captured in the form of ATP .'The electrons are transferred to smaller molecules known as electron carriers.The electron carriers take the electrons to a group of proteins in the inner membrane of the mitochondrion,called the electron transport chain.As electrons move through the electron transport chain they go from a higher to lower energy level and are finally passed to Oxygen to form water.The energy released is captured as a proton gradient which powers the production of ATP.
Not 100% sure whether it's the correct answer but the concept is true 100% btw I stand to be corrected
Answer:
A. Chemical energy originally stored in the glucose molecule.
Explanation:
Lol, I feel you. Bio can be a pain, confusing and tricky sometimes.

Explanation:
Atmospheric carbon dioxide dissolves into ocen surface waters
Answer:
Carbon dioxide, which is naturally in the atmosphere, dissolves into seawater. Water and carbon dioxide combine to form carbonic acid (H2CO3), a weak acid that breaks (or “dissociates”) into hydrogen ions (H+) and bicarbonate ions (HCO3-).

Imagine customers moving into and out of a coffee shop. Which situation
resembles how a reaction in dynamic equilibrium acts?
A. There are the same number of people inside the coffee shop as
outside it.
B. People enter the coffee shop at the same rate as others leave.
C. No people are moving either into or out of the coffee shop.
D. Some people sit down and drink their coffee slowly, while others
drink theirs quickly while standing up.
No
Answer:
B. People enter the coffee shop at the same rate as others leave.
Explanation:
did the test !!
The answer is B. People enter the coffee shop at the same rate as others leave.
In a reaction in dynamic equilibrium, the forward and reverse reactions occur at the same rate, meaning that the concentrations of reactants and products remain constant over time.
Similarly, in the coffee shop scenario, if people are entering and leaving at the same rate, the number of customers inside the shop will remain constant, just like the concentrations of reactants and products in equilibrium.
Option A, C, D are not a good analogy for dynamic equilibrium.
