If mutations in the genes in apoptotic pathway blocked apoptosis then a cell with such damage could continue to divide and lead to cancer.

Apoptosis has a preventive role in eradicating a cell that may contribute to cancer by being triggered by the p53 protein when a cell has significant DNA damage.

Single amino acid changes in p53 caused by TP53 gene mutations make the protein less functional. Without p53, cell proliferation is not efficiently controlled, and DNA damage can build up in cells. Such cells may continue to divide uncontrollably, resulting in the development of tumors.

Answer:

1.) d.

2.) a.

3.) c.

4.) b.

Explanation:

Homozygous (same zygote) means both alleles in a chromosome pair are either both dominant, represented by a capital letter, or both recessive, represented by a lowercase letter.  

Homozygous dominant genotypes would be represented by two uppercase letters, for this problem GG (d.).

Homozygous recessive would be represented by two lowercase letters, for this problem gg (a.).

Heterozygous (different zygote) means the subject genes in a chromosome pair have a dominant and a recessive allele.  These genotypes are represented by an uppercase and lowercase letter, for this problem Gg (c.).

Phenotypes are the physical manifestations of a genotype.  For this problem, the only physical attribute is blue eyes (b.).

Answer:

Molecules from food and molecules of oxygen move from the mouth and the nose to cells of the body through a series of blood vessels, including veins, arteries, and microscopically small blood vessels (capillaries), that extend throughout the body.

The list of sequence of these events from oldest to youngest (most recent) depicted in Cross-Section III is D, A, B, E, and C.

Among a series of sedimentary rock layers, the rule of superposition asserts that the oldest layer is at the bottom and that as the sequence ascends, the layers get progressively younger.

In other words, the older or younger rock strata are found at the top. Older rock strata are located near the bottom. Due to the fact that each layer of silt is layered on top of the previous one, scientists may understand rock strata.

It should be emphasized that this knowledge contributes to the geological time scale of Earth's history and helps geologists determine the history of Earth's rocks.

Therefore, the correct sequence of events is D, A, B, E, and C.

The answer responses are given below:

1. The Once-ler's success in making and selling Thneeds could be seen as either a good or a bad thing, depending on how one views the consequences of his actions. On the one hand, the Once-ler's success suggests that he is a skilled and hardworking entrepreneur who is able to meet the needs and desires of his customers. This could be seen as a good thing in that it demonstrates his ability to provide value and create wealth for himself and others.

On the other hand, the Once-ler's success is also accompanied by negative consequences, such as the destruction of the Truffula Trees and the disruption of the ecosystem. These negative consequences could be seen as making the Once-ler's success a bad thing, as they result in harm to the environment and the creatures that depend on it.

2. Cutting down one tree may not necessarily be harmful, but cutting down many trees can have negative consequences, particularly if it results in the loss of a large portion of a particular ecosystem. Trees play important roles in the environment, such as providing habitat for wildlife, regulating the climate, and maintaining soil health. When many trees are cut down, these functions may be disrupted, leading to negative impacts on the animals and plants that depend on them.

3. When the Once-ler starts cutting down the Truffula Trees, the Brown Bar-ba-loots are forced to leave their habitat because they depend on the Truffula Trees for food. This happens because the Once-ler's actions have disrupted the ecosystem, making it no longer suitable for the Bar-ba-loots to live in. The Once-ler's actions do harm the Bar-ba-loots by forcing them to leave their home.

4. The Once-ler keeps expanding his business after the Brown Bar-ba-loots leave because he is focused on making money and increasing his profits. He believes that everyone needs Thneeds because he is convinced that his product is useful and necessary for everyone. However, this belief may not necessarily be true, as the needs and wants of individuals vary.

5. The Swomee-Swans and Humming Fish leave because their habitats are destroyed due to the Once-ler's deforestation and expansion of his business. The Once-ler doesn't care about what is happening around him because he is only concerned with his own financial gain, rather than the impact his actions have on the environment and the animals that live there.

6. The problems faced by the Bar-ba-loots, Swomee-Swans, and Humming Fish are all related to the Once-ler cutting down Truffula Trees because the destruction of these trees destroys the animals' habitats and disrupts their ecosystems. This can also happen in real life, as deforestation and environmental destruction can have negative impacts on the animals and ecosystems in an area.

7/ The Once-ler keeps expanding more and more because he is driven by a desire for financial success and is not considering the long-term consequences of his actions. His actions may be morally wrong because they are causing harm to the environment and the animals that live there, and may not be sustainable in the long run. When similar actions happen in real life, they can also be morally wrong if they cause harm and are not sustainable.

These circumstances, which are shown in bold above, compete with one another for survival, variation, and inheritance. According to some, these circumstances are both essential and sufficient for natural selection to take place.

Heritable variation serves as the initial source of variation for natural selection. There must already be variation in a characteristic for natural selection to work on it, and that variation must be transmissible to offspring.

Within a cell, the amount of protein made using a given mRNA molecule depends partly on the concentration of ribosomes and other cellular machinery involved in protein synthesis. Protein synthesis is the process by which cells translate the genetic information encoded in mRNA molecules into the sequence of amino acids that make up a protein.

This process requires the participation of several different cellular components, including ribosomes, tRNAs, and enzymes. Ribosomes are the molecular machines that catalyze the formation of peptide bonds between amino acids, tRNAs are the molecules that carry individual amino acids to the ribosomes, and enzymes are the proteins that help to facilitate the reaction.

The amount of protein that can be made using a given mRNA molecule is limited by the availability of these components. If the concentration of ribosomes and other machinery is low, then the rate of protein synthesis will be slowed, and less protein will be produced. On the other hand, if the concentration of these components is high, then the rate of protein synthesis will be increased, and more protein will be produced.

Overall, the amount of protein made using a given mRNA molecule depends partly on the concentration of ribosomes and other cellular machinery involved in protein synthesis. By controlling the availability of these components, cells can regulate the rate of protein synthesis and the amount of protein produced.

A sarcomere spans from Z disk to Z disk. option A

A sarcomere is the basic unit of contraction in a skeletal muscle fiber. It spans from one Z disk to the next Z disk along the myofibril. The Z disks are protein structures that anchor the thin filaments of actin. The sarcomere contains overlapping thick and thin filaments that slide past each other when the muscle contracts or relaxes.

The thick filaments are composed of myosin and are located in the center of the sarcomere, forming the A band. The thin filaments are composed of actin and are attached to the Z disks, forming the I band. The H zone is the region of the A band that has no thin filaments. The M line is the protein structure that holds the thick filaments together in the middle of the sarcomere.

An example of a sarcomere is shown below:
