List 2 organelles found in an animal cell and explain how those 2 organelles benefit the cell.
Answer:
I chose nucleus and the mitochondria
Explanation:
The nucleus is particularly important among eukaryotic organelles because it is the location of a cell's DNA. Two other critical organelles are mitochondria and chloroplasts, which play important roles in energy conversion and are thought to have their evolutionary origins as simple single-celled organisms.

Cell includes a cell membrane, cytoplasm and cell organelles. Cell organelles are mitochondria, golgi bodies, nucleus, ribosomes, vacuoles, lysosomes, centrioles, etc.
What are cell organelles?Cell organelles are the structures present in cell that are responsible to carry out necessary processes and maintains homeostasis.
This can include nucleus, mitochondria, golgi bodies, ribosomes, etc.
Nucleus: Nucleus is a membrane bound cell organelle that contain an entangled thread like structure called as chromatin material. This chromatin material condenses at the time of cell division and forms chromosomes. Nucleus also contain nucleolus that helps in formation of ribosomal units. it contains a fluid called as nucleoplasm.Ribosome is the organelle that is involved in formation of protein. It has two subunits i.e. a smaller one and a bigger one. these subunits are joined at the time of protein synthesis and are formed in nucleolus of nucleus.
Thus, these were explanation of two cell organelles along with their explanation.

The government wants to set new regulations that prohibit chlorofluorocarbons (CFCs) use in aerosol sprays and refrigerants. How will this act help with the sustainability of our environment?
Answer:
The new regulation will help reduce the amount of green house gases available in the atmosphere thereby saving our environment from the Green house effect
Explanation:
Chlorofluorocarbons are examples of greenhouse gases which contribute to the Green house effect been experienced in our environment, by destroying the earths' Ozone layer
If the Government sets a new regulation that prohibit its use in sprays and refrigerants it will help reduce the amount of green house gases available in the atmosphere thereby saving our environment from the Green house effect
Answer:
that act will help the sustainability of out environment because : C. It will slow down the degradation of the ozone layer
The usage of CFC will crate chlorine atoms that catalyze ozone degradation. By prohibiting this product, Government will slow down Ozone's degradation

The nucleotide sequence of a strand of DNA TAC -CGG-AGTWhat the amino acid sequence of the resulting protein ?
The amino acid sequence would be "Met-Ala-Ser."
What is a nucleotide sequence?A nucleotide sequence is a linear arrangement of nucleotides, the building blocks of nucleic acids such as DNA and RNA. Nucleotides are composed of a nitrogenous base, a sugar molecule, and a phosphate group. There are four different nitrogenous bases in DNA: adenine (A), cytosine (C), guanine (G), and thymine (T). In RNA, thymine is replaced by uracil (U).
The specific order of these nitrogenous bases in a DNA or RNA molecule encodes genetic information, which is used by cells to carry out various functions such as protein synthesis. The nucleotide sequence determines the structure and function of a nucleic acid molecule and plays a crucial role in the processes of heredity and evolution. The study of nucleotide sequences and their function is a central part of the field of molecular biology and genomics.

white sands national monument in New mexico has hundreds of miles of white sand dunes made of gypsum crystals. which of the following would you expect to be true of white sands national monument?
a. it receives no radiation
b. it is immune to insolation
c. it has a high albedo
d. it has no heat capacity
Gypsum, a soft mineral frequently left behind when water bodies evaporate, is what gives the sands of White Sands National Monument a high albedo their texture, hence option C is correct.
What is white sands national monument?Despite being a very common mineral, gypsum is rarely found as sand because it readily dissolves in water and is often transported to the sea by rivers.
The dunes seem white like snow additionally, gypsum doesn't absorb heat from the sun as silica sand does.
Therefore, gypsum is actually a transparent material, but due of the frequent collisions between the grains,, hence option C is correct.

Teniendo en cuenta problemáticas de la biología o de su aprendizaje ,pensar un tema investigar desde el enfoque cualita tivo y otro desde el enfoque cuantitativo
Answer:
Caso de estudio: El efecto de estresores ambientales sobre el comportamiento animal
- Ejemplo de un tipo de estudio cualitativo: la influencia de estresores ambientales (por ej. niveles anormales de dióxido de carbono atmosférico) sobre el comportamiento en ratones de laboratorio
- Ejemplo de un tipo de estudio cuantitativo: la influencia de estresores ambientales sobre los niveles de producción de hormonas asociadas a cambios comportamentales en ratones de laboratorio
Explanation:
Un enfoque cualitativo se caracteriza por el hecho de que la información obtenida durante dicho estudio se agrupa en categorías mutuamente excluyentes. En biología, los estudios de tipo cualitativo generalmente se caen dentro de la dicotomía observacional (es decir, presencia o ausencia del factor en estudio). En el ejemplo arriba citado, es posible obtener datos relacionados a uno o más determinado aspectos comportamentales en los individuos bajo estudio (por ejemplo, presencia o ausencia de signos de irritabilidad) en ratones sometidos a algún estresor ambiental (por ejemplo, niveles anormales de CO2 atmosférico). Por otra parte, en un enfoque cuantitativo, la información se recopila en intervalos obtenidos a partir de operaciones aritméticas (estadística paramétrica). En el ejemplo, los datos obtenidos pueden ser clasificados en intervalos referidos a los niveles hormonales. Esta información resulta útil para determinar si las diferencias en los niveles hormonales entre individuos que se encuentran en presencia del estresor ambiental son estadísticamente significativas respecto al grupo control (individuos desarrollados en un ambiente con niveles normales de CO2 atmosférico), y de este modo concluir si el estresor ambiental puede o no modificar variables comportamentales. Los estudios cualitativos permiten el uso de variables independientes las cuales son clasificadas como cualitativas (discretas).
what is the next step in the scientific method, following forming a hypothesis?
A. Analyzing the data
B. stating the question
C. conducting an experiment
Hi there!
The answer to this question, I believe, would be C, conducting an experiment. When you make your hypothesis, you have already stated your question, analyzed the data, and formed a logical assumption that you need to prove is true. Your hypothesis is your logical assumption; therefore, you ought to experiment and see if your assumption - your hypothesis - is correct.
Hope this helps! :)
Answer:
Conducting an experiment
Explanation:
In response to a decrease in tissue metabolic activity, tissue oxygen concentrations ________, which causes a(n) ________. In response to a decrease in tissue metabolic activity, tissue oxygen concentrations ________, which causes a(n) ________. increase : active hyperemic response decrease : dilation of the arterioles decrease : increase in tissue ischemia decrease : active hyperemic response increase : constriction of the arterioles
Answer:
The correct answer is - increase: constriction of the arterioles.
Explanation:
When the physical activity is decreased by the tissues of the muscle, the oxygen concentration in the tissue increases which leads to the constriction of the arterioles.
It takes place in order to decrease blood flow and blood pressure as oxygen requirement is less in the tissue in decreased physical metabolic activity. The constriction of arterioles results in more resistance to decrease the blood flow in capillaries.
