Cycle energy and matter to support the biosphere as a closed energy system
Explanation:
The earth as we know it is a closed energy system that is, matter cannot be introduced or removed from it. Sometimes, rare meterites enter into the system with minimal or no disruption.
Also, energy can enter and leave. The energy mostly referenced here is the sun.
Within the earths system, the lithosphere, hydrosphere, and biosphere materials and energy go through a cycle which helps to support life.
For example, water when heated up by the sun rises as vapour from the earth and oceans into the atmosphere where it cools and condenses. When it cools and condenses, it , in the form of rain, comes down on the earth and oceans. As rain falls down to the earth and runs off the rocks, rocks are broken down into smaller fragments and soils. The hydrosphere comprises of all water bodies on earth. Besides the vapours which are evaporated from the same into the atmosphere, when volcanoes erupt they also send vapourised water into the atmosphere.
So because the earth is a closed system, a change in one sphere effects a change in others. An example is a change in the water cycle.

Answer:
The correct answer is - mitochondria.
Explanation:
Mitochondria is an organelle that is double-membrane organelle and known as the power center of the cell as it produces chemical energy during a process is known as cellular respiration.
Aerobic cellular respiration is a process for the conversion of fats and carbohydrates into chemical energy or ATP in the mitochondria in presence of the oxygen.
Thus, the correct answer is - mitochondria.
Aerobic cellular respiration takes place in the mitochondria of eukaryotic cells. Therefore, the correct option is D.
Aerobic cellular respiration occurs in the mitochondria of eukaryotic cells, which uses oxygen to break down organic molecules, primarily to form ATP. Because of their function in ATP synthesis, the double-membrane organelles known as mitochondria are often referred to as the "powerhouses" of the cell. They have an inner membrane with several folds called cristae that increase the surface area available for chemical reactions, as well as an outer membrane.
Therefore, the correct option is D.

A meteorologist who has been analyzing weather data from the last fifty years found evidence of climate change. An ecologist has been studying deposits of pollen from the last fifty years to track the types of plants that grew
in certain regions. She has also found evidence of climate change. What does this imply about science?
Meteorology and ecology are the same type of science
When scientific disciplines overlap, researchers should choose new topics
O Different scientific disciplines can be used to investigate similar questions
There should be fewer sciences, as they seem to answer the same questions
The correct answer is C. Different scientific disciplines can be used to investigate similar questions
Explanation:
The general purpose of science is to study, analyze, and understand the world and especially natural phenomena. Moreover, science includes multiple disciplines with different focuses; for example, astronomy focuses on objects in the space.
Despite this, all disciplines in sciences have objective methods. This causes scientists to obtain the same results or findings even if they belong to different disciplines, and therefore, the same questions or phenomena can be studied from different disciplines. An example of this is that a meteorologist and an ecologist find evidence of climate change. According to this, "different scientific disciplines can be used to investigate similar questions".

Mutations in several different genes that encode enzymes in the pathway for the synthesis of the heme group may cause a genetic disorder called methemoglobinemia. The symptoms of this disorder range form mild to death in the most severe cases. The enzyme cytochrome b5 reductase is one of the enzymes in this pathway. This enzyme is responsible for reducing the iron in the heme group to the ferrous state so that it can bind oxygen. Kobayashi et al. reviewed several mutations in this gene. One of these mutations causes a Ser to Pro substitution. Explain what nucleotide change and in which position in the codon can cause this amino acid change. Assign all possible appropriate terms to this mutation.
Answer:
Please find the explanation of the nucleotide change below
Explanation:
Mutation is any change that occurs to the nucleotide sequence of a gene. According to this question, a substitution mutation which causes the Serine amino acid to change to Proline amino acid in the cytochrome b5 reductase enzyme is described.
A substitution mutation is a type of mutation in which one or more nucleotide base is replaced by another. The mRNA codons that specify Serine and Proline amino acids are as follows:
Serine: UCU, UCC, UCA, UCG, AGU, AGC
Proline: CCU, CCC, CCA, CCG
Based on the observation of these bases, URACIL BASE in the first four listed codons for serine amino acid is replaced by CYTOSINE BASE. i.e.
UCU (serine) -> CCU (proline)
UCC (serine) -> CCC (proline)
UCA (serine) -> CCA (proline)
UCG (serine) -> CCG (proline)
Notice that these base substitutions (U-C) occur in the 1st position of the codon.

A strange new species of plant has been discovered. When studying the chromatin from the cells of this plant using the kinds of experiments described above in (b) a 120-bp fragment of DNA is seen. Analysis of the histone core reveals histones in the following proportions: H2A 33.3% H2B 33.3% H3 0% [no histone H3 found] H4 33.3% On the basis of these observations, what conclusions can you make about the probable structure of the nucleosome in the chromatin of this plant? Be specific in describing the nature of the nucleosome: which histones form the core (1pt), how many of each are in there (1pt) and how much core-DNA is around it (1pt).
Answer:
The nucleosome core is composed of two each of histones H2A and H2B and H4
Explanation:
The nucleosome is the basic structural unit of all eukaryotic genomes. A nucleosome is composed of approximately 146 base pairs of DNA sequence wrapped around a core of histone proteins, which generally consists of two subunits of the histones H2A, H2b, H3 and H4, respectively (i.e., an octamer of histone proteins). Within the cell nucleus, the large DNA molecule is coiled into nucleosomes, this structure is further compacted into chromatin fibers and subsequently into higher-order organization structures to finally form a chromosome.

A manager wanted to test whether the amount of noise in a clothing factory affected how
much work employees accomplished. Three groups of employees were tested every day
over a 5-day period. All three groups did the same type of work, they were all equally trained
to do the work, they used the same equipment, and they were tested the same time of day.
Group one was given headphones that blocked out all of the outside noise. Group two was
given headphones that blocked out some of the noise. Group three was not given anything
to block out the noise. The number of shirts made by the employees in one hour was
determined.
What is the independent/manipulated variable?
the amoutn of noise
the number of shirts made by the employee
the type of music the employees listen to while they work.
The amount of training employees need.
Answer:
When seeking to determine the number of shirts made by employees subjected to noise with and without the use of headphones, the independent variable is the amount of noise.
Explanation:
During an investigation, the independent variable may be subject to change, in order to observe the effect it will have on the dependent variable.
In the case presented, the amount of noise to which employees are exposed represents the independent variable, which is modified by the use of headphones that block all or part of the noise.
The productivity —expressed in the number of shirts made— can be expected to be higher for employees not exposed to noise.
Other options do not apply because:
The number of shirts made by the employee. Dependent variable .The type of music the employees listen to while they work or the amount of training employees need. These are not the variables studied.How is osmosis different from diffusion?

Write a sentence or two connecting these terms highlighting each: Genes, genetics, Genome, protein, trait.
Answer:
Please find the sentence below
Explanation:
GENETICS is the study of individual genes present in the GENOME of an organism. In the GENOME, which is the complete set of GENES in an organism, genes that contain the information needed for the synthesis and transmission of useful products called PROTEINS undergo genetic expression. Gene expression involves two major processes viz: transcription and translation.
Transcription involves the synthesis of an mRNA from the information encoded by a GENE while translation involves the synthesis of a PROTEIN from the information encoded by the mRNA transcript. The produced protein is responsible for bringing about certain TRAITS, which are observable characteristics, in living organisms.
Therefore, the central dogma of biology is the process that sees GENE converted to mRNA and mRNA converted to PROTEIN.
