Answer:
Bacteria develop resistance mechanisms by using instructions provided by their DNA. Often, resistance genes are found within plasmids, small pieces of DNA that carry genetic instructions from one germ to another. This means that some bacteria can share their DNA and make other germs resistant.

Which statement explains one way that minerals form?
O They are mined from rocks.
O They are produced from molten minerals.
O They are grown in a laboratory.
O They are washed up on a seashore.
Answer:
O They are produced from molten minerals.
Explanation:
Minerals can be produce form molten rocks or materials in nature.
Minerals are solid inorganic compounds with a definite composition and an ordered atomic arrangement.
Minerals are naturally formed. When rocks melt, they can aggregate or concentrate certain minerals in parts of the melt. This process known as differentiation takes place at different temperature and pressure conditions in a molten rock.what happens during metaphase 1 that leads to genetic variation?
Answer: In metaphase I, the tetrads line themselves up at the metaphase plate and homologous pairs orient themselves randomly. This variation is due to independent assortment and crossing-over during meiosis, and random union of gametes during fertilization.
Explanation:
Answer:
In metaphase I, the tetrads line themselves up at the metaphase plate and homologous pairs orient themselves randomly. This variation is due to independent assortment and crossing-over during meiosis, and random union of gametes during fertilization. In metaphase I, the orientation of homologous pairs is random as they line up along the center of the cell. Each homologous pair can line up in two different ways. Differences in the homologous pairs' orientation in metaphase I lead to variation in how the chromosomes are separated and grouped together in anaphase I.
Changes in the orientation of tetrads along the center of the cell vary the combination of chromosomes in the resulting daughter cells.

Summarize the process of cellular respiration in your own words. Consider where you get the initial glucose from and all of the outputs when making your summary.
The cellular respiration process is as follows:
Glucose is the main sugar that circulates in the blood and is the first source of energy in the body for living beings that comes from the food we eat.Through the oxidation of glucose, various compounds are produced that provide energy, the body absorbs sugar from food and transforms it into energy thanks to metabolic activity.Said metabolic reactions is known as cellular respiration that take place inside the cells of living beings, through which chemical energy is obtained from the decomposition of organic molecules.The process of cellular respiration consumes glucose as fuel and oxygen as final electron receptor (oxidant) in reaction with pyruvic acid.Thus, carbon dioxide (CO2), water (H2O) and numerous amounts of ATP, the molecule of biochemical energy, are obtained.Therefore, we can conclude that cellular respiration involves a metabolic process by which glucose is initially oxidized and energy and water are produced.

Why do we say chloroplasts look like green footballs even though a lot of the time they look like perfect green spheres?
Answer:
Explanation:
The football used in American Football is an oval. Chloroplasts can be spherical but also oval-shaped. For the rest of the world, football is what people in the U.S. call soccer. So a football can also be spherical in shape and thus chloroplasts can be spherical just like footballs are. Chloroplasts can also be disc-shaped.

A student conducted an experiment to test whether talking to plants would help them to grow faster. He set up the following two groups: Group 1: spoken to and hand watered Group 2: not spoken to and watered with sprinklers After three weeks, the plants in Group 1 showed much more growth than those in Group 2. Based on the results of this experiment, which is the best conclusion?
A researcher must keep constant all the variables that are not of interest, so they can not affect the experiment results. B) They are not valid because the student did not control all the variables that can affect plant growth.
What are the variables involved in an experiment?Independent variable
This variable is the one that affects the response of the dependent variable. Any change that occurs in the independent variable will rebound on the dependent variable and will be reflected in the experiment results.
Dependent variableThis variable is the one that completely depends on other variables, meaning that any change that occurs in other variables will cause a modification on this one. It depends on the independent variable.
When conducting an experiment, several variables might affect the results. Since the researcher is only interested in studying how the independent variable influences the dependent one, he or she must keep constant all the remaining variables so they will not influence the response.
Controlled variables -constant variable-
These are all the other variables that must be kept under control so they do not affect the results of the experiment. Their values or states must be constant in the control and experimental groups.
In the exposed example, the student is interested in knowing how talking to plants would help them to grow faster.
Independent variable ⇒ talking to plants
Dependent variable ⇒ plants' growth rate
In this case, the constant variable should be the way in which the student provide water to the plants. However, the students use two different ways to water the plants: hand watering and with sprinklers.
Since this last variable is not controlled and is not constant in the control and the experimental group, it will indeed affect the plants' growth rate.
The experiment fails in keeping constant the controlled variable.
The correct option is B) They are not valid because the student did not control all the variables that can affect plant growth.

Rey, who has a normal vision (XY),married Cindy
who has a normal vision but carries a gene for
color-blindness (XX) What is the chance to
have a colorblind baby girl?
Answer:
There is no chance that Rey —who has a normal vision man— and Cindy, who is a woman colorblind carrier, will have a colorblind daughter.
Explanation:
If a man with normal vision and women who is a carrier of colorblindness has a daughter there is a 50/50 chance of having a colorblindness carrier daughter. And all daughters would have normal vision.
Color blindness is a visual condition characterized by the inability to discern some colors, and has a recessive inheritance pattern linked to the X sex chromosome. This means that all males with the defective gene (Xd) would be color blind, while a female to be color blind must have both X chromosomes affected.
In the case of Rey and Cindy
♂ XY
♀XdX
Alleles X Y
Xd XdX XdY
X XX XY
Of the daughters they have, half could be carriers, while the other half would not have the altered gene. In any case, none of their daughters could be colorblind.
