An ichnofossil is any part of the hard skeleton left behind by a vertebrate in the fossil record. This statement is false. An ichnofossil is a trace fossil, which is any indirect evidence of past life, such as tracks, burrows, and feces. It is not part of the hard skeleton left behind by a vertebrate.

Cladograms are scientific hypotheses that can be overturned by new data. This statement is true. Cladograms are diagrams that show the evolutionary relationship between organisms based on various traits. New data can cause changes to be made to cladograms which can result in a change to the interpretation of the evolutionary history of organisms.

Angiosperm plants did not appear until after the extinction of the dinosaurs. This statement is false. Angiosperms, also known as flowering plants, appeared in the fossil record at least 140 million years ago. Although the dinosaurs went extinct around 66 million years ago, angiosperms were already widespread and diversifying by that time.

The definition of an analogous character is "a character that has a similar function to a character in a different organism, but these similarities are due to different evolutionary origins".

The Giant Impact Theory is most likely to account for how the Moon formed, although there are other hypotheses as well, such as the Colliding Planetesimals Hypothesis, the Capture Hypothesis, and the Accretion Hypothesis.

The gravitational pull of the Earth, which holds the Moon in orbit, is balanced by the gravitational pull of the Moon, which pulls on our planet in turn and causes the oceans to move, forming a tidal bulge. This tidal bulge really sits just in front of the Moon because of the Earth's rotation.

A collision between the proto-Earth and a planetesimal the size of Mars occurred roughly 4.5 billion years ago in the Hadean eon, 20 million to 100 million years after the solar system originated. This collision is known as the Theia Impact or the "giant impact hypothesis."

The Giant Impact Theory suggests a Mars-sized object hit Earth with force, causing debris to form a disk, which eventually coalesced to form the Moon.

The Giant Impact Theory is a scientific hypothesis that explains how the Earth's moon was formed. According to this theory, the Moon was created from the debris left over after a Mars-sized body collided with the Earth about 4.5 billion years ago, shortly after the formation of the solar system. This collision caused a massive explosion and ejected a large amount of material into space, which eventually coalesced to form the Moon.

The theory is supported by various lines of evidence, such as the similarity in chemical composition between the Earth and Moon, as well as the Moon's relatively large size compared to its parent planet. The Giant Impact Theory is widely accepted by the scientific community as the most plausible explanation for the origin of the Moon.

PHOTOSYNTHESIS:

- Light energy is absorbed

- Glucose and oxygen are products

- Carbon dioxide and water are inputs

- Chemical energy is produced

CELLULAR RESPIRATION:

- Carbon dioxide and water are outputs

- Chemical energy is released

- Glucose and oxygen are inputs

- ATP, motion and heat energy are produced

Explanation:

- Photosynthesis is process by which autotrophic organisms synthesize their food (glucose) in the presence of sunlight. The process combines carbon dioxide (CO2) and water (H20) to produce glucose (C6H12O6) and oxygen (O2), by the energy derived from absorbing light. In the process, light energy is transformed to chemical energy (glucose). The reaction is as follows:

6CO2 + 6H2O → C6H12O6 + 6O2

- Cellular respiration is the opposite of photosynthesis as it involves the metabolic breakdown of glucose molecule to produce energy usable by the cell (ATP). Cellular respiration combines glucose and oxygen (inputs) to yield carbon dioxide and water (outputs). ATP, motion and heat energy are produced in the process. The equation is as follows:

C6H12O6 + 6O2 → 6CO2 + 6H2O

The model takes into account the birth rate (kb N(t)) and death rate (kd N(t)) of bacteria, where kb and kd are two different constants and N(t) is the number of bacteria at any time.

The mathematical model that describes this situation is called an ordinary differential equation (ODE) and is written as kb N(t) - kd N(t) = (kb - kd) N(t). This equation states that the rate of change of the number of bacteria over time is equal to the difference between the birth rate and death rate of bacteria.

The limiting situation for increasing time occurs when the population of bacteria reaches a maximum value and can no longer increase. This occurs when the birth rate and death rate of bacteria are equal, meaning that the rate of change of the number of bacteria over time is zero.

Transcription is mRNA synthesis, which occurs by complementing a segment of the DNA template strand. The translation is the protein growth, which occurs by adding amino acids coded by mRNA codons. C) the polypeptide is 6 amino acids long.  

The whole process of protein synthesis includes Transcription and translation.

TRANSCRIPTION

Transcription is the mRNA synthesis process and occurs in the nucleus.

The DNA template strand is read in direction 3'→ 5' to build the mRNA molecule in direction 5'→ 3'. The template strand is the one that is going to be complemented by the mRNA.

mRNA molecule has the same sequence as the DNA coding strand, but it carries uracil instead of thymine.

TRANSLATION

Translation is the process through which polypeptide grows. It occurs in the cytoplasm.

rRNA and tRNA read mRNA in the direction 5'→ 3' and add the correct amino acids to build the new protein.

Amino acids are coded by mRNA codons. Protein synthesis initiates in the AUG start codon -Metionin- and ends when reaching either of the stop codons UAA, UAG, or UGA.

In the exposed example, we have a DNA strand. We know that it is the coding strand, so it has the same sequence as mRNA molecule.

5' AATCCGTATCTATGACCGTTTGGAAACACTAAGCGGTACTC 3'

5' AAUCCGUAUCUAUGACCGUUUGGAAACACUAAGCGGUACUC 3'

Kowing mRNA sequence, we can grow the protein.

So first, we need to find the initiation codon (AUG), begining from the mRNA 5' extreme. Then we need to find a stop codon (UAA, UAG, or UGA).

5' AAUCCGUAUCUAUGACCGUUUGGAAACACUAAGCGGUACUC 3'

5' AAUCCGUAUCUAUGACCGUUUGGAAACACUAAGCGGUACUC 3'

So this protein begins in AUG and ends in UAA.

To grow the protein, we need to separate mRNA codons and find the corresponding amino acids.

According to this reasoning, the polypeptide is 6 amino acids long. Option C) is correct.

Despite having negative biotic interactions, two species can coexist through various mechanisms that allow them to persist in the same habitat.

Two species with negative biotic interactions, such as competition or predation, can still coexist by partitioning resources or adopting different ecological niches. Resource partitioning occurs when species utilize different resources within their shared environment, reducing direct competition for limited resources. This allows each species to occupy a specific niche and minimize interference with one another. Another mechanism is the evolution of specific adaptations or behaviors that reduce the negative effects of interactions, such as prey developing defensive mechanisms against predators.

Additionally, the population dynamics of the interacting species can be influenced by density-dependent factors, where the intensity of the negative interaction may change with population size.

DNA methylation is a process in which a methyl group is added to the cytosine nucleotides of DNA. This modification often occurs in regions called CpG islands, which are rich in cytosine and guanine nucleotides.

Methylation of cytosine can cause the DNA to wrap more tightly around the histones, making it less accessible to transcription factors and other proteins that need to bind to the DNA in order to regulate gene expression. This can have important consequences for the cell, as changes in DNA methylation patterns can alter the expression of genes and contribute to the development of diseases such as cancer.

                   When cytosine is methylated, it can affect the way that DNA interacts with histones, which are proteins that help to package DNA into a compact structure known as chromatin.

"DNA methylation of cytosine nucleotides causes DNA to wrap more tightly around histones."

DNA methylation is a chemical process where a methyl group is added to the cytosine nucleotide, one of the four nucleotides in DNA.
This addition of a methyl group typically occurs at a CpG site, where a cytosine nucleotide is adjacent to a guanine nucleotide.
When methylation occurs, it can affect the way DNA interacts with histone proteins.
Histones are proteins that help package and organize the DNA within the cell nucleus.
The DNA wraps around histone proteins to form a structure called nucleosomes, which further condense to form chromatin.
Methylation of cytosine nucleotides can cause DNA to wrap more tightly around histones by altering the accessibility of DNA-binding proteins.
This tighter wrapping can lead to transcriptional repression, which means that the genes in the methylated region may be less likely to be expressed.

In conclusion, DNA methylation of cytosine nucleotides can result in DNA wrapping more tightly around histones, which may ultimately affect gene expression.

The main system that maintains the internal fluid environment by acting as an intermediary between the blood in the capillaries and tissue cells is the lymphatic system.

The lymphatic system is a network of vessels, nodes, and organs that is responsible for the transport of lymph, a fluid derived from interstitial fluid, throughout the body. The lymphatic system plays a crucial role in maintaining fluid balance and immune function.

In the capillaries, blood plasma is filtered out into the surrounding tissues, forming interstitial fluid. This fluid contains nutrients, oxygen, and other substances necessary for the cells. However, not all of this fluid is reabsorbed by the capillaries. Excess interstitial fluid, along with waste products and cellular debris, is collected by the lymphatic vessels.
