Write the definition for the word Homologous (include an example) IN YOUR OWN WORDS.

During anaphase I of meiosis, homologous chromosomes move to opposite poles of the cell, whereas during anaphase II of meiosis, sister chromatids are separated and moved to opposite poles of the cell.

In meiosis, the process of cell division that produces haploid gametes (eggs and sperm) from diploid germ cells is called meiosis. Meiosis is a type of cell division that reduces the number of chromosomes in a cell from diploid (2n) to haploid (n) (1n). The two homologous chromosomes, each consisting of two sister chromatids, are paired during meiosis I, resulting in a bivalent structure known as a tetrad. During anaphase I of meiosis I, the homologous chromosomes separate and are pulled towards opposite poles of the cell. The spindle fibers attached to the homologous chromosomes shorten, causing the chromosomes to move apart.

The homologous chromosomes migrate towards opposite poles of the cell during this stage, while the spindle fibers attached to the kinetochores pull the chromosomes towards the poles. The sister chromatids are separated and move to opposite poles of the cell during anaphase II of meiosis. The chromatids are separated and pulled apart by the spindle fibers during this phase. The spindle fibers pull the chromatids towards opposite poles of the cell, causing the cell to divide and produce four haploid daughter cells at the end of meiosis II.

The dark structure in the center of onion peel cells is the nucleus. The nucleus serves as the control center of the cell, containing the genetic material in the form of DNA. It regulates the cell's activities by directing the synthesis of proteins and coordinating cell division.

The main function of the nucleus is to store and protect the genetic information necessary for the cell's functioning and inheritance. It contains the DNA molecules, which are organized into chromosomes. Within the nucleus, DNA is transcribed into RNA, which then serves as a template for protein synthesis. The nucleus also plays a critical role in cell division, as it regulates the replication and distribution of genetic material during mitosis and meiosis.

Additionally, the nucleus is involved in various cellular processes, including gene expression, DNA repair, and the regulation of cell cycle progression. It helps maintain the integrity and stability of the genetic material and ensures the proper functioning and specialization of cells. Overall, the nucleus is a vital organelle in the onion peel cells and other eukaryotic cells, playing a crucial role in cellular activities and inheritance.

Explanation:

a. The overall colonization rate of the entire metapopulation. The colonization rate of the entire metapopulation is the answer.

The metapopulation equation: dP/dt=[cP(1−P)]−ePHere, cP(1-P) is the birth term, which is the product of the colonization rate and the number of individuals in patches not occupied yet. eP is the death term, which is the product of the extinction rate and the number of individuals in patches occupied but about to go extinct. Thus, the equation gives us the number of patches that are empty and the patches with checkerspot butterflies. Therefore, the overall colonization rate is 2.3. b. The overall extinction rate of the entire metapopulation. The extinction rate of the entire metapopulation is 1.3. This is because 1.3 patches of the occupied 9 patches are going to become extinct.

c. Are the colonization and extinction rates likely to be at equilibrium with each other? How do you know? Both colonization and extinction rates are unlikely to be in equilibrium with each other because the colonization rate is higher than the extinction rate. Therefore, the occupied patches' population will continue to increase until the patches are fully occupied, while the number of empty patches will continue to decrease until the patches are fully occupied.

Answer:

Emphysema is one of the lung disorders caused by damage to the air sacs in the lungs, which reduces the body's ability to take advantage of oxygen from the air. This results in inefficient breathing, because it takes extra effort to empty the air from the lungs. This disease progressively destroys the fibers that allow the airways to remain open. This problem causes the collapse of these pathways when a person exhales air. That is, the air that the lungs expel that contains carbon dioxide cannot get out, and consequently, the fresh, oxygen-filled air does not enter the lungs.

Explanation:

When we breathe, the air comes through the bronchial tree to a kind of small sacs called alveoli, which are located at the end of the bronchi and fill the lungs. From the lungs, oxygen is transported, through the arteries, to the different tissues and organs of the body. But, generally due to smoking, people with emphysema have damaged alveoli: the inner walls of these sacs weaken and break, which creates larger air spaces and therefore reduces the air exchange surface of the cells lungs. Consequently, the amount of oxygen that reaches the blood decreases and this can produce in the patient a sensation of shortness of breath, which is the frequent characteristic manifestation of this respiratory pathology. In the pulmonary alveoli, the oxygen in the air is exchanged for carbon dioxide in the blood. The walls of the air sacs are thin and fragile, so the injuries that occur in these air sacs are irreversible. Emphysema causes the alveoli - the small air sacs in the lungs that provide oxygen to the bloodstream - to weaken and they become less elastic. That means the body has difficulty getting enough oxygen or has excess carbon dioxide in the body.

My answer is down below. Don't directly copy because you will get plagiarism, and that's not what I want to happen to you. The only reason why I posted my answer is if you are in need of some help to think of things to write. Hope you enjoy it!

Explanation:

One of the sad things about this disease is that we currently do not have a cure for it. Which is very unfortunate for the people that end up getting it. There is some hope of relieving some pain, but there isn't a 100% cure. What emphysema does is it destroys the walls between your alveoli. What happens to your lungs? Well, it makes the lungs less able to absorb oxygen into our bloodstream and also remove carbon dioxide from our blood. The good news/bad news is that if you are diagnosed with emphysema you are likely to still live anywhere from 1-5 more years, which is pretty amazing that our body can last that long with damaged lungs.

An example of a prey and predator that co-evolve due to the Red Queen Hypothesis is the cheetah (predator) and the impala (prey) in the African savannah. The impalas evolve to become faster and more agile, enabling them to outrun cheetahs.

The impalas develop longer legs, allowing for increased stride length and higher running speeds, as well as enhanced agility through improved coordination and quick directional changes. On the other hand, cheetahs develop longer, more muscular bodies to improve their acceleration and top speed. They also possess sharper claws for better grip during high-speed chases.

These changes occur because faster impalas have a higher likelihood of escaping predation, while faster cheetahs have a better chance of catching their prey. Thus, natural selection favors individuals within each species that possess advantageous traits, leading to the co-evolutionary chase between the predator and prey.

Photosynthesis is a complex process that can be summarized in two key steps: the light-dependent reactions and the light-independent reactions (also known as the Calvin cycle).

In the light-dependent reactions, light energy is converted into chemical energy in the form of ATP and NADPH. In the light-independent reactions, ATP and NADPH are used to convert carbon dioxide into glucose.

During the light-dependent reactions, light energy is absorbed by chlorophyll and other pigments in the chloroplasts of plant cells. This energy is used to split water molecules, releasing oxygen as a byproduct.

The energy from the absorbed light is then used to convert ADP (adenosine diphosphate) into ATP (adenosine triphosphate) and NADP+ (nicotinamide adenine dinucleotide phosphate) into NADPH. These energy-rich molecules, ATP and NADPH, are essential for the next step.

In the light-independent reactions, also known as the Calvin cycle, carbon dioxide enters the chloroplasts and combines with a five-carbon compound called RuBP (ribulose-1,5-bisphosphate). This process is facilitated by the enzyme RuBisCO (ribulose-1,5-bisphosphate carboxylase/oxygenase).

The resulting unstable six-carbon molecule quickly breaks down into two molecules of a three-carbon compound called PGA (phosphoglycerate). ATP and NADPH from the light-dependent reactions provide the energy and reducing power to convert PGA into PGAL(phosphoglyceraldehyde) through a series of enzymatic steps. Some PGAL molecules are then used to regenerate RuBP, while others combine to form glucose and other organic compounds.

Overall, photosynthesis is a remarkable process where plants capture light energy and convert it into chemical energy in the form of glucose, which serves as a fundamental energy source for both plants and other organisms in the food chain.

Based on the data you found, about 80 of the 100 aliens would become thin if the temperature were 35°C. Thus, the correct option is C.

Aliens are the extraterrestrial livings or outer space creatures found in the galaxy. Their life and growth are entirely different from what on the earth and it depends on the climate of the planet where they live as well.

Reports have been found to claim that only dehydration, which is a direct effect of temperature, affects the aliens directly. But, if that were the case, we can anticipate the removal of the impact of temperature through keeping the aliens from becoming dehydrated.

However, this does not happen because shifting the temperature slider still causes the aliens to change from thick to thin, and regardless of how high the water slider temperature is set. The impact of temperature is independent of hydration.

Therefore, the correct option is C.
