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.

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.

what are extinct animals ?
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.

What will happen if there were no enzymes to aid in reactions
Answer:
Digestive enzymes speedup reactions that break down large molecules of carbohydrates, proteins, and fats into smaller molecules the body can use. Without digestive enzymes, animals would not be able to break down food molecules quickly enough to provide the energy and nutrients they need to survive.

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.
What benefit does an organism gain by only using this method of reproduction?
Explanation:
In a stable or predictable environment, asexual reproduction is an effective means of reproduction because all the offspring will be adapted to that environment. In an unstable or unpredictable environment asexually-reproducing species may be at a disadvantage because all the offspring are genetically identical and may not have the genetic variation to survive in new or different conditions. On the other hand, the rapid rates of asexual reproduction may allow for a speedy response to environmental changes if individuals have mutations. An additional advantage of asexual reproduction is that colonization of new habitats may be easier when an individual does not need to find a mate to reproduce.
What can we NOT learn from the fossils found in rock strata?
Answer:
The location of fossils in rock layers provides evidence of Earth's past landscapes. It is hard to guess the age of rock. Scientists have to act like detectives, piecing together a mystery to determine how long ago rocks formed. Fossils found in a particular rock layer help scientists determine the age of the rock.

Hope this helps you, may i have brainliest please.
What we cannot learn from the fossils found in rock strata is: the diversity of organisms at a certain location or during a certain time period.
Rock strata (layers) that are found in various parts of the world are usually different from one another because they all comprises distinct Earth's geological history, which are referred to as fossils.
A fossil can be defined as the mineral impression or remains of both living and non-living organisms that are prehistoric in nature.
This ultimately implies that, fossils are ancient organisms such as plants and animals that were formed into rocks.
Some of the information that can be learnt from the fossils found in rock strata are:

A. It would grow until there was no more space.  B. It would decrease steadily over time.  C. It would keep growing with no limit.  D. It would grow until it had to compete for food.
The Malthus predict about the human population as it would grow until it had to compete for food. Therefore, option (D) is correct.
What are the characteristics of human population?The total number of people alive today is referred to as the world population. In the middle of November 2022, the United Nations estimated that it had reached more than eight billion.
There are 4 primary qualities of the populace structure: age, orientation, nationality, and thickness. The population structure is influenced by three main factors: Migration, mortality, and the birth rate.
Understanding how populace attributes, for example, size, spatial dissemination, age structure, or the birth and demise rates change over the long haul can assist researchers or legislatures with simply deciding.
