Answer:
The stages of cellular respiration are: Glycolysis, pyruvate oxidation, Krebs cycle and phosphorylative oxidation.
The fermentation stages are: glycolysis and pyruvate regeneration.
Explanation:
Cellular respiration is a biochemical process that occurs in all aerobic organisms and aims to promote the obtaining of the necessary energy so that the cells can perform the activities they need to perform. Cellular respiration occurs in mitochondria and oxygen must be present in the process.
Fermentation is the biochemical process that replaces cellular respiration in organisms that do not survive in the presence of oxygen, the anaerobic organisms that are some fungi and bacteria. Fermentation also aims to produce cellular energy.
If each person inherits two copies of any given gene from their parents, those who inherit two copies of the same gene variants are known as homozygous individuals. Those who inherit two different variants of the gene are known as heterozygous individuals. Determine the zygosity of samples 1, 2, and 3. DNA sample 1 DNA sample 2 DNA sample 3 Zygosity (homo/hetero) Allele contained (TNF1 and TNF 2)
Zygosity refers to the genetic composition of an individual with regards to a specific gene, indicating whether the individual is homozygous (inherits two identical copies of a gene) or heterozygous (inherits two different copies of a gene).
For the samples 1, 2, and 3, the zygosity can be determined based on the alleles contained in each sample. The alleles are variations of a gene and are indicated as TNF1 and TNF2.
If sample 1 contains two copies of TNF1, the individual is homozygous for TNF1. If sample 2 contains one copy each of TNF1 and TNF2, the individual is heterozygous for TNF. If sample 3 contains two copies of TNF2, the individual is homozygous for TNF2.
In summary, the zygosity of a sample is determined by the presence of different or identical copies of a gene. Homozygous individuals have two copies of the same gene variant, while heterozygous individuals have two different gene variants.

On a given microscope, the numerical apertures of the condenser and low power objective lenses are 1.25 and 0.25 respectively. You are supplied with a filter that selects a wavelength of 520 nm.
a. What is the limit of resolution of this microscope?
b. Will you be able to distinguish 2 points that are 300nm apart as being separate, or will they blur into one?
Answer:
a. Resolving power (R) = 346.7 nanometers (nm)
b. No, because the resolving power is 346.7 nm
Explanation:
In microscopy, resolution or resolving power (R) refers to the minimum distance at which two distinct points can still be distinguished as separate entities. R can be calculated by the following equation:
Resolving power (R) = wavelength /(NAo + NAc), where NAo is the numerical aperture of the objective and NAc is the numerical aperture of the condenser. In the case above described:
R = 520 nanometers / (1.25 + 0.25) = 346.7 nanometers (nm)
In consequence, the resolving power of this microscope at 520 nanometers of wavelength is 346.7 nm, thereby two points separated by 300 nm will be too close to be distinguished as separated objects.

Human, cat, whale and bat have similar forelimb bone structure with a different functions. These homologous structures show
Answer:
The correct answer is - that They share a common ancestor.
Explanation:
The bones of forelimbs of whale, bat, cat, and human are similar in structure due to the fact they are homologous organs. Such organs which have the same basic structure but play a different role in their respective bodies are called homologous organs.
These organs are developed from the same organization during their development but due to evolutionary change in their environmental condition and their requirement, these organs are modified to perform different functions. The homologous structures are end result of divergent evolution which means they show common ancestry.

In a laboratory experiment, a plant receives sunlight and water, but not carbon dioxide. Predict what happens to the plant and construct an explanation for your prediction using what you know about the light-dependent and light-independent reactions.
A plant that receives sunlight and water but not carbon dioxide will not be able to produce carbohydrates
PhotosynthesisThe process whereby light photosynthesized can broadly be divided into 2:
Light-dependent reactionsLight-independent reactionsThe products from the light-dependent reactions are used to fix carbon dioxide into glucose in the light-independent reaction.
Thus, without carbon dioxide, the light-dependent reaction will take place normally while the light-independent reaction cannot because the major reactant is lacking.

When a stone is dropped into water, it disturbes the surface of the water, this is called
When a stone is dropped into water, it disturbs the surface of the water, and this is called "ripples" or "waves".
The disturbance caused by the stone creates waves that travel away from the point where the stone entered the water. These waves can be seen as ripples spreading outwards from the point of impact. The size and shape of the ripples depend on various factors, such as the size and weight of the stone and the depth and temperature of the water.
As the waves move away from the point of impact, they carry energy with them. This energy is transferred to the water molecules as the waves pass by, causing them to move up and down. The movement of the water molecules creates a wave pattern that can be seen on the surface of the water.
The ripple effect caused by a stone dropped into water is a simple example of how energy is transferred through a medium. It is also a common visual metaphor used to describe the way in which small actions can have large and far-reaching consequences, as the ripples caused by the stone continue to spread outwards in all directions, affecting everything in their path.

compare and contrast a community and a ecosystem
A community is a group of populations that habit a given geographic area, while an ecosystem also includes abiotic factors.
What is a community?In ecology, a community can be defined as a group of populations of different species that live together in a given area. Conversely, an ecosystem is a community, and also abiotic factors such as temperature that interact to shape the environment.
Therefore, we can conclude that a community is different of the term ecosystem because this last one also include abiotic factors instead of only biotic factors (i.e, group of populations).

HOMOLOGOUS CHROMOSOMES SEPERATE FROM EACH OTHER WHAT STAGE
Answer:
Homologous chromosomes separate from each other during anaphase I of meiosis.
Explanation:
Meiosis is a specialized type of cell division that occurs in sexually reproducing organisms. It involves two rounds of cell division, known as meiosis I and meiosis II, which result in the formation of haploid gametes (sperm or eggs) with half the number of chromosomes as the parent cell.
During meiosis I, homologous chromosomes pair up and exchange genetic material in a process called crossing over. Then, during anaphase I, the homologous chromosomes separate from each other and migrate to opposite poles of the cell. This is followed by telophase I, cytokinesis, and the formation of two new cells, each with a haploid set of chromosomes.
In contrast, during meiosis II, the sister chromatids of each chromosome separate from each other and migrate to opposite poles of the cell, resulting in the formation of four haploid daughter cells.

The chanterelle mushrooms in a forest are found to grow only in association with oak and beech trees.
How would the chanterelle population change if a tree disease killed the beech trees in the forest?
OA It would become extinct.
OB. It would be reduced in size, but would survive.
OC. It would adapt to grow in association with other trees.
OD. It would kill the oak tree population by making too many demands on its resources.
OE it would stay the same because more mushrooms would grow in association with oak trees.
If a disease kills the beech trees in the forest, the chanterelle mushrooms will likely survive but reduce in population size.
Obligate associationsSince the mushrooms are found to only live in association with oak and beech trees, the relationship with the trees can be said to be obligatory.
Without the two trees in the forest, the mushroom will likely go extinct.
However, if a disease should kill only the oak trees in the forest, the mushroom would still survive but only in association with the beech tree.
Thus, the population will reduce but survival will likely be sustained.
