2. Humans have an appendix, a thin tube connected to the large intestine that serves no purpose and is a
threat to human health and life if it becomes infected and/or inflamed. It is believed that the appendix
once had a function as part of the human digestive system. The human appendix, therefore, is

Using a slow- and fast-growing variant of bamboo, Wei and colleagues looked at cell division, growth, and gene expression (through transcriptomics, which measures all the genes being expressed by an individual) to discover which genes may be responsible for fast growth in bamboo. They found that the slow-growing variant had reduced expression of genes relating to cell wall construction, the plant hormone auxin (important for cell growth and cell division), and had irregular cell growth and cell walls. Wei and colleagues suggest that a reduced ability to produce and perceive auxin, combined with a weakened cell wall, are responsible for the slow growth seen in the bamboo variant.

Explanation:

(A) A fossil fuel is a fuel formed by natural processes, such as anaerobic decomposition of buried dead organisms, containing organic molecules originating in ancient photosynthesis that release energy in combustion

(B) After millions of years underground, the compounds that make up plankton and plants turn into fossil fuels. Plankton decomposes into natural gas and oil, while plants become coal. Today, humans extract these resources through coal mining and the drilling of oil and gas wells on land and offshore.

(C) These non-renewable fuels, which include coal, oil, and natural gas, supply about 80 percent of the world's energy. They provide electricity, heat, and transportation, while also feeding the processes that make a huge range of products, from steel to plastics.

Explanation:

Cell cycle checkpoint controls play a major role in preventing the development of cancer [see Sherr, 1994, for a more detailed discussion]. Major checkpoints occur at the G1 to S phase transition and at the G2 to M phase transitions. Cancer is a genetic disease that arises from defects in growth-promoting oncogenes and growth-suppressing tumor suppressor genes. The p53 tumor suppressor protein plays a role in both the G1/S phase and G2/M phase checkpoints. The mechanism for this activity at the G1/S phase checkpoint is well understood, but its mechanism of action at the G2/M phase checkpoint remains to be elucidated. The p53 protein is thought to prevent chromosomal replication specifically during the cell cycle if DNA damage is present. In addition, p53 can induce a type of programmed cell death, or apoptosis, under certain circumstances. The general goal of p53 appears to be the prevention of cell propagation if mutations are present. The p53 protein acts as a transcription factor by binding to certain specific genes and regulating their expression. One of these, WAF1 or Cip1, is activated by p53 and is an essential downstream mediator of p53-dependent G1/S phase checkpoint control. The function of p53 can be suppressed by another gene, MDM2, which is overexpressed in certain tumorigenic mouse cells and binds to p53 protein, thus inhibiting its transcriptional activation function. Other cellular proteins have been found to bind to p53, but the significance of the associations is not completely understood in all cases. The large number of human cancers in which the p53 gene is altered makes this gene a good candidate for cancer screening approaches.

or something like that

Answer:

True

Explanation:

A gene pool is all of the genes present in a particular population. Each type of gene within a gene pool may exist in one or more alleles. The prevalence of an allele within the gene pool is described by its allele frequency. ... If it is polymorphic, each allele has a frequency that is between 1 and 99%.

Answer:

The amount of CO2 found in the atmosphere varies over the course of a year. Much of this variation happens because of the role of plants in the carbon cycle. Respiration happens all the time, but dominates during the colder months of the year, resulting in higher CO2 levels in the atmosphere during those months.

Hypothesis: Earthquakes and tsunamis are caused by tectonic plates in the Earth's crust. When the crust moves, they occur, depending on the location of the crust.

Answer:

Most times a earthquake is what causes a tsunami, such as a deep ocean earthquake causing a tsunami to form. Most tsunamis are formed that way because deep ocean earthquakes create so much force.

Umm every sense of organs travels in the spinal cord.

Most nerves of one of the sense organs go to the spinal cord before they go to the brain, and that organ is the one that is involved in the reflex action because it happens in a very short time and is controlled by the spinal cord before the brain..

Reflex actions are important because they allow the body to respond quickly to stimuli without waiting for the brain, and they can be especially important in situations where a quick response is necessary to avoid danger, such as when the hand touches hot substances and the hand suddenly goes back, which is due to the motor neuron action of the spinal cord.

Hence, most nerves of one of the sense organs go to the spinal cord before they go to the brain, and that organ is the one that is involved in the reflex action because it happens in a very short time and is controlled by the spinal cord before the brain.

Explanation:

The internal environment consists of water based fluid in which the cells of the body present. A fluid called interstitial fluid or tissue fluid bathes the cells and provides essential nutrients to the cell. The human skin has fatty layers that helps to maintain internal heat which is produced by the body when the outside environment is cold. When there is cold in the environment, people lives in warm shelters and wear warm clothes in order reduce the impact of cold environment.

Answer:

The correct answer is - brown heterozygous Bb and blue eye bb.

Explanation:

In the provided question it is given that there are 20 babies born, 10 babies had blue eyes and 10 had brown eyes. As it is known that brown eyes are dominant over blue eyes, therefore, on the basis of this we can say that all blue-eyed babies have a bb genotype and as brown eyes are dominant traits babies must have at least one copy of the B allele which represents brown eye trait.

case1:

Parent 1 : bb

parent 2: BB

   B      B

b  Bb   Bb

b   Bb   Bb

there are 100% brown eye offspring so this is not the case

case 2:

Parent 1 : bb

parent 2: Bb

   B      b

b  Bb   bb

b   Bb   bb

here, 50% brown eyes and 50% blue eyes offspring produced thus, the parent trait will be brown heterozygous and blue eye.

The processes that considerably turn carbon compounds into the atmosphere are the decaying of organisms, the respiration of animals, and emissions from automobiles and factories. Thus, the correct options for this question are B, C, and E.

The carbon cycle may be defined as a type of biogeochemical cycle through which carbo and its derivative products are exchanged among the various spheres of the earth's surface. Carbon is considered one of the main components of biological systems.

In the carbon cycle, rhe process of photosynthesis utilizes the carbon from the atmosphere in order to produce chemical energy in the form of glucose. While the excretion of animal waste products is responsible for nitrogenous compounds like urea or ammonia.

Except for these two, all other options are directly liberating carbon into the atmosphere which can easily be demonstrated in the carbon cycle.

Therefore, the correct options for this question are B, C, and E.
