Efecto adverso sobre la salud.
Explicación:
El crecimiento lento de los niños afecta la salud de los niños, haciéndolos más susceptibles a enfermedades e infecciones, pero también afecta su desarrollo mental y físico. Las inyecciones de hormona del crecimiento y los medicamentos de reemplazo de la hormona tiroidea son tratamientos que se usan para tratar el crecimiento lento en los niños. La deficiencia de la hormona del crecimiento se puede tratar mediante inyecciones de hormona del crecimiento.

The manure pit has been emptied and Ted now has to enter the manure pit to perform some maintenance work. He is hooked up to a lifeline and his colleague Sam is outside the pit ready to assist should a rescue become necessary. Do you notice any issues in this scenario?
The pit if empty so there is no need for additional precautions
Ted is wearing a lifeline so there is no need for additional precautions
Sam should be wearing a self-contained breathing apparatus
Ted should be wearing a self-contained breathing apparatus
Answer:
D. Ted should be wearing a self-contained breathing apparatus
Explanation:
According to this question, Ted has entered into an empty pit in order to do some maintenance work and his colleague, Sam, is outside the pit ready to assist him in case of emergency.
It is necessary to take additional precautions even if Ted is tied to a lifeline or the pit is empty. However, the additional precaution should be that Ted should be wearing a self-contained breathing apparatus (SCBA) in case of breathing or respiratory problems down the pit.
Two samples of radioactive material from the same rock is prepared for testing. Sample A is cut into a 2 inch cube. Sample B is crushed into a fine powder. Compared to the half-life of the material in Sample A, the half-life of the material in the powdered Sample B is:
Answer:
The same
Explanation:
Half life is the time taken for the number of atoms in a radioactive sample to decrease to half of the initial number of atoms. It is also the time taken for the activity of a radioactive sample to decrease to half of its original value.
If samples A and B were obtained from the same rock, then they contain the same number of atoms having the same initial activity even though the samples were not prepared in the same way for analysis.
Hence, samples A and B have the same half life.
Based on the living things in the pyramid, please tell me what examples would fit into these categories
Primacy Producers, primary consumers, secondary consumers, and tertiary consumers.
Answer:
Primacy Producers----- Oak tree , primary consumers------ Caterpillars , secondary consumers ------- blue jays, and tertiary consumers ----- hawk.
Explanation:
Oak tree refers to the primacy Producers in this pyramid because it produces food by using the solar energy. Caterpillars are primary consumers that feeds on the producers and also known as herbivores, blue jays are the secondary consumers that feeds on the primary consumer which is the caterpillar, and tertiary consumers are the hawk that feeds on the secondary consumer i.e. blue jays. In this way, energy flows in the food chain of an ecosystem. During this flow of energy, only 10% of energy is transferred from one trophic level to another while the remaining releases in the environment in the form of heat energy.
Students filled two beakers with 500 mL of water each. They placed three drops of live algae culture into each of the beakers, then used a dissolved oxygen sensor to measure the oxygen content of the water in each beaker. The students then stirred 5 mL of nitrogen-rich fertilizer into one of the beakers, and labeled the beaker A. Nothing was added to the second beaker, which the students labeled B. Both beakers were placed under a high-intensity light over a weekend. On Monday, the students measured the amount of oxygen in the water of each of the beakers. Which aspect of the watershed were these students trying to model?
A. The effect of fertilizer-contaminated surface water flowing as runoff into a waterway
B. How stagnant or non-flowing water can result in providing a habitat for living organisms such as algae
C. The inverse relationship between water, light, oxygen, and photosynthesis
D. How light and oxygen levels in water affect the growth of algae within a system over time
D. How light and oxygen levels in water affect the growth of algae within a system over time
HELP QUICK . Come up with an explanation as to why there is some advantage to a dark mouse in a lighter habitat
but not lighter mice in darker environments ?
The darker mouse could hide in the shadows easier where hunters won't look and a lighter mouse in. darker habitat would stand out more than anything around it and result in it being easy prey.
I hope this helps ^^
The advantage to a dark mouse in a lighter habitat but not lighter mice in darker environments is predators could more easily spot the dark mice on light sand.
What are the characteristics of predators?Predators are organisms that hunt and kill other organisms for food. The organisms that are consumed by the predators are known as the prey. Predators can be carnivores and omnivores.
There are four commonly recognized types of predation: (1) carnivory, (2) herbivory, (3) parasitism, and (4) mutualism. Each type of predation can by categorized based on whether or not it results in the death of the prey.
Some examples of predator and prey are lion and zebra, bear and fish, and fox and rabbit. The words "predator" and "prey" are almost always used to mean only animals that eat animals, but the same concept also applies to plants.

Research that seeks to understand the source of water pollution for given body of what is an example of applied science
Answer:
True
Explanation:
Research that seeks to understand the source of water pollution for given body of what is indeed an example of applied science.
Applied science is a branch of science that deals with the application of scientific knowledge to solve real-life problems. This is as opposed to natural science which deals mainly with the physical world and is largely theoretical. When the theoretical knowledge obtained from natural science is put to real use to solve existing problems, it is termed applied science.

D. nucleus
E. vacuole
HELP!
i believe the answer is c, cell wall^^
Cell wall supporting part of the plant cell. So, the correct option is C.
What is Cell wall?A cell wall is defined as the structural layer surrounding certain types of cells present outside the cell membrane which can be rigid, flexible and sometimes rigid. The cell wall provides both structural support and protection to the cell which serves as a filtering mechanism.
Cell wall present only in plants and some fungi, bacteria and algae. The plant cell wall is arranged in 3 layers which are composed of carbohydrates, such as pectin, cellulose, hemicellulose and other small amounts of minerals, which form a network with structural proteins to form the cell wall.
Thus, Cell wall supporting part of the plant cell. So, the correct option is C.

Which of the following do we get from biodiversity?
Explanation:
Utilitarian values include the many basic needs humans obtain from biodiversity such as food, fuel, shelter, and medicine. Further, ecosystems provide crucial services such as pollination, seed dispersal, climate regulation, water purification, nutrient cycling, and control of agricultural pests.
Biodiversity supports human and societal needs, including food and nutrition security, energy, development of medicines and pharmaceuticals and freshwater, which together underpin good health. It also supports economic opportunities, and leisure activities that contribute to overall wellbeing.

Which statement best predicts why a cell's progression through the cell cycle might be halted by the G1/S checkpoint?
Answer:
The missing options are:
A. Spindle fibers have not correctly attached to chromosomes.
B. Damage occurred to DNA when it was being copied in G1.
C. There are not enough nucleotides available to construct new DNA.
D. Proteins necessary for M phase of the cell cycle have not been produced.
The correct option is C.There are not enough nucleotides available to construct new DNA.
Explanation:
During the G1 phase, the cell grows in size since it prepares its organelles and molecule combinations for the next phase of the cell cycle, the S phase. Before the cell transitions to the S phase, it has to pass through a checkpoint that makes sure that there are no mutations, it has grown enough, and has the necessary molecules for the next phase, which is the synthesis of DNA. If there are not enough nucleotides, the cell will not be able to synthesize new DNA in the S phase, so the checkpoint stops the cells from moving to this phase till it has all the necessary things to do it.
