Answer:
Scientists use waves to study the different layers of the earth. Usually, they use seismic waves, which are waves generated by earthquakes or nuclear-test explosions. The seismic waves are bent, sped up, or slowed down, or even reflected when they pass through the earth's layers.

C. first appearance of most invertebrates
D. dominance of non avian dinosaurs
Answer:
C) first appearance of most invertebrates.
Explanation:
The Cambrian Explosion occurred 542 mya. The earliest complex animals arose in the sea at the beginning of the Cambrian Explosion. It would take another half a billion years for mammals to rise. Multicellular life dates back 1.2 bya, but more cpomplex life, such as animals, did not occur until the Cambrian Explosion. In the beginning of the Cambrian Explosion, many soft-bodied animals, such as jellyfish and sea anemones appeared.

Comparing the four most common types of power plants in Alberta (coal, natural
gas, wind, and hydroelectric), which has the lowest efficiency in electricity
generation? and why?
Answer:
Coal.
Explanation:
Steam power plant has the lowest efficiency in electricity production which can only be run with the use of fossil fuels such as coal. The efficiency of this power plant is the lowest because large amount of coal is converted into smoke and other gases and very less amount of coal into heat energy. This coal is used to produce heat energy which can be used in the heating of water to produce steam. This steam is used to move turbines which turn mechanical energy into electric energy.

A. The baby boy inherited the father's genes only
B. The baby girl inherited the mother's genes only
C. Both the baby boy and girl baby inherited the parent's genes
D. Baby boy inherit father's genes while baby girls inherit mother's genes
Madam Annie gave a birth to a pair of twins, a male and a female. Both the baby boy and girl baby inherited the parent's genes. This is because of the inheritance that is being passed on to children via the heredity.
What kind of division is present in the gametes formation ?
Meiosis is present in the gametes formation where the chromosomes set will be halved.
In the case of offspring it is the mix of both the mother and the genes of the father where they both need to express themselves in order to determine the genotype and the phenotype of an individual. Genetic recombination takes place in the case of progeny especially in the sexual reproduction.
In the case of sexual reproduction, it is one set coming out from one parent and one from another set and they express together making a child hybrid definitely the frequency of expression can be changing but the child is having traits of both.

The diagram below represents the time a cell spends in the two main phases
of the cell cycle. Which section of the diagram represents the phase during
which the cell divides, and what is this phase called?
A. Yellow area: Interphase
B. Yellow area: M phase
C. Blue area: M phase
0 D. Blue area: Interphase
Answer:
The yellow ares is m-phase
Explanation:
This is where the cell divides into two nucleus.
The blue area in the diagram represents the phase during which the cell divides, and this phase is called the M phase or mitotic phase. Therefore, option C is the correct.
What is mitotic phase?The mitotic phase, also known as the M phase, is the phase of the cell cycle during which a single cell divides into two identical daughter cells. This process of cell division is essential for growth, development, and repair of tissues in multicellular organisms.
The M phase consists of four stages: prophase, metaphase, anaphase, and telophase. During these stages, the replicated chromosomes condense and align at the metaphase plate, separate and move towards opposite poles of the cell during anaphase, and then decondense and form two separate nuclei during telophase.
The M phase is tightly regulated by a complex network of checkpoint pathways that ensure the accurate segregation of chromosomes and prevent the formation of abnormal cells, which can lead to diseases such as cancer.

Provide a detailed explanation of why meiosis is important in creating genetic variation in a population. Include details on how daughter cells receive genetic information and how they differ from parent cells.
Answer:
The correct answer is - crossing over, mutations caused during crossing over, and independent assortment.
Explanation:
Meiosis is important as it helps that all organisms form via sexual reproduction contains the correct number of chromosomes in the offspring. Meiosis also produces genetic variation in various ways that are crossing over, mutations caused during crossing over, and independent assortment.
Independent assortment helps in getting half number of chromosomes. In meiosis, crossing over takes place in prophase 1 which results in recombination by an exchange in the arms of chromosomes.

multiple biomes in a biosphere
2.
multiple ecosystems in a biome
3.

multiple individuals in a population
4.

The set of ecological organization levels that is most likely to contain the largest variety of species is: multiple biomes in a biosphere.
LEVEL OF ECOLOGICAL ORGANIZATION:
Ecology refers to the study of plants and animals (biotic) in relation to their environment. The level of organization in an ecological setup involves an hierarchical build up. The level of organization in ecology from the least to the highest is as follows: individual species → population → community → ecosystem → biome → biosphere. As the level increases, the more the species contained. This means that a community will contain more species than a population. Therefore, the largest variety of species is most likely to be found in the highest level of organization, which is multiple biomes in a biosphere.Learn more at: https://brainly.com/question/18536684?referrer=searchResults

Human body cells are constantly moving water into and out of themselves. Under what conditions can a human body cell achieve homeostasis?
Homeostasis is the process by which the body maintains a stable internal environment despite changes in external conditions. The body has several mechanisms to help maintain overall fluid balance, such as the renin-angiotensin-aldosterone system and the anti-diuretic hormone (ADH) system.
What is homeostasis?Human body cells are constantly moving water into and out of themselves, and they rely on a complex system of transport proteins and channels to regulate the movement of water and other molecules. Under normal conditions, human body cells can achieve homeostasis by maintaining a balance between the concentration of solutes inside and outside the cell. This balance is maintained through a process known as osmoregulation, which involves the movement of water and solutes across the cell membrane.
Hence, homeostasis is the process by which the body maintains a stable internal environment despite changes in external conditions. The body has several mechanisms to help maintain overall fluid balance, such as the renin-angiotensin-aldosterone system and the anti-diuretic hormone (ADH) system.

When hypothesizing a possible phylogeny in order to classify taxa,scientists incorporate systematics to
A)provide primarily morphological information.
B)provide molecular or genetic information,as well as morphological information.
C)name organisms using a genus and specific epithet.
D)create a hierarchy of classification based upon reproductive mating patterns.
Answer:
B)provide molecular or genetic information, as well as morphological information.
Explanation:
Systematics is the science of classification and phylogeny reconstruction. Studies diversity as a consequence of evolutive history and establishes the bases to reconstruct biological patterns and formulate hypotheses to explain the processes of these patterns. It reconstructs the origin and diversification of a taxon. Systematics creates systems of classification represented in a tree. Taxonomy is based on systematics.
The main goal of systematics is to solve the genealogical relationship between different species and biological groups that produces natural clusters.
Systematic considers morphological characters, as well as physiological, cytological, molecular, and behavioral characters.
