What do ribosomes produce following
instructions from the nucleus?
A. energy
B. proteins
C. DNA
Answer: Here's what I could find:
Ribosomes get their orders for protein synthesis from the nucleus, where portions of DNA (genes) are transcribed to make messenger RNAs. An mRNA travels to the ribosome and uses information it contains to build a proteins with specific amino acid sequences.
Explanation: I'm pretty sure it's protein, if not then it's DNA.
4a. By 40-60 years after farm fields had been abandoned, the amount of herbaceous plants
decreased. Give one reason why the amount of herbaceous plants decreased as the amount of trees
increased.
Answer:
See the answer below
Explanation:
The amount of herbaceous plants in an abandoned farm field will keep decreasing with time and the amount of trees would be increasing instead due to successional forces.
Succession refers to the gradual change in the species structure of a community with time. Early successional species usually colonize new habitats and with time, they are replaced with late successional species until a relatively stable community, climax community, is established.
Herbaceous species on abandoned farmland represent early successional species and as time goes on, they will be replaced by mid to late successional species in the form of shrubs and trees until a relatively stable community is formed. Hence, herbs would be decreasing while trees would be increasing.
What conclusion can you draw from the presence of the adult blowfly eggs on the corners of Anna's mouth and nostrils? Group of answer choices The Lab had a broken screen that allowed flies to enter from the outside. Anna has been dead for more than a few hours. Her killer must have placed them there to throw us off their track. These fly's mean nothing.
Answer:
Anna has been dead for more than a few hours.
Explanation:
With the presence off eggs shows us that there was enough time for the flies to discover her and lay the eggs.
You have learned that each one of your cells contains one copy of your unique genome. Given the fact that all the cells in one human contain the same DNA, how is it possible that our cell types are so different, resulting in four different tissue types?
Answer:
See the answer below
Explanation:
Yes, the cells in one human contain the same DNA. However, during gene expression, not all the genes are expressed for every cell. Only a specific region of the DNA is expressed in cells and the cells in which the same DNA region is expressed end up performing similar roles in the body of organisms. The portion of the DNA that is expressed dictates the function which these cells will serve. This is called the differentiation of cells.
Cell specialization and tissue differentiation are due to the fact that although somatic cells have the same DNA, they express different genes and therefore generate different cells/tissues.
The human body contains approximately 200 cell types, which can be classified into four types of tissues: epithelial tissue, connective tissue, muscle tissue, and nervous tissue.
All these tissues and cell types are derived from three embryo layers, i.e., ectoderm, mesoderm, and endoderm.
The process of differential gene expression from these three embryo layers leads to the development of different types of cells/tissues in different regions of the developing embryo.
For example, the expression of the connective tissue growth factor (CTGF) gene has been associated with the generation of connective tissue during embryo development.
In conclusion, cell specialization and tissue differentiation are due to the fact that although somatic cells have the same DNA, they express different genes and therefore generate different cells/tissues.

The Sun is the main source of energy for all the subsystems of Earth. Identify the subsystem that can store the most energy from the Sun due
to its high heat capacity.
Answer:
Water
Explanation:
Just took post test for edmentum
Nearly all climatic and biological activities on Earth depend on solar energy, which is the primary energy driving our climate system. Numerous Earthly processes, such as surface warming, evaporation, photosynthesis, and air circulation, depend on energy from the sun.
What are the Sun is affected by its high heat capacity?The sun heats the earth's surface, and as the air above it warms as well, wind is produced. Water evaporated by the sun produces clouds and rain, which in turn give us moving rivers and streams.
As a result of the heat being introduced to the system doing some pressure-volume work at constant pressure, the heat capacity at constant pressure is higher than the heat capacity at constant volume.
In a system with heat capacity at constant volume, the entire heat input is used to increase the temperature.
Therefore, Energy comes from both the wind and moving water (hydropower). So you can see, the sun is the source of a variety of natural energies.

Answer:
F2 generation
Explanation:
If mice from the F1 generation are crossed, their offspring are the F2 generation.
What are the characteristics of F2 generation?F2 second filial generation is the generation of individuals which arises as a result of inbreeding of interbreeding amongst individuals of F1 generation.
A second filial generation or F2 generation is a group of people born as a result of inbreeding and interbreeding among members of the same family. The generation of hybrids formed from a cross between genetically diverse people is known as the first filial generation.
First-generation (F1) progeny only showed the dominant traits, but recessive traits reappeared in the self-pollinated second-generation (F2) plants in a 3:1 ratio of dominant to recessive traits.

A nurse made a tragic mistake and hooked a sick patient up to an IV line that included pure water. The contents of the IV bag were then injected into the patient. The patient is now getting sicker. What could be happening?
Answer:
The water is hypotonic to the body of the patients
Explanation:
Pure water is generally hypotonic to the red blood cells in the body of humans. Hence, if a person is hooked up to an IV line that included pure water, the red blood cells in the person's body will take-in water, become turgid, and then start lysing. This will make the person become sick or even cause death in severe cases.

Which technique would most probably involve using a magna brush to detect a latent print?
A.
carbon powder dusting
B.
ninhydrin exposure
C.
iron powder dusting
D.
silver nitrate exposure
E.
superglue fuming
The technique that would most probably involve using a Magna brush to detect a latent print is known as Iron powder dusting. Thus, the correct option for this question is C.
What is Latent print?Latent print may be defined as an impression of the friction skin of the fingers or palms of the hands that have been transferred to another surface. The permanent and unique arrangement of the features of this skin allows for the identification of an individual as a latent print.
Iron powder is commonly placed into brake pads, drum brake lining, and other applications in order to construct the necessary amount of friction. Iron powder dusting is a type of technique that is utilized as a filler that can help increase the performance and durability of these products by dissipating the generated heat.
