The phrase "survival of the fittest" refers to the process of natural selection, a mechanism that promotes evolutionary development. Natural selection works by favoring individuals who are more suited to a particular set of environmental conditions over those who are not.
Because it brings new variety into the population, mutation is the only method of evolution identified that increases the quantity of genetic variation. Genetic drift is the loss of genetic variation caused by chance over time.

Over a period of several hours, a barometer shows rapidly decreasing air pressure. What type of weather will most likely occur next?
Answer:
Explanation:
Normally, when the atmosphere changes. Then the temperature either to reduces or increase. The act of the temperature going up and down then creates the condition that makes us have night and the daytime.
This also causes the change in pressure that gets detected by a barometer.
When the temperature is high, it can form snow. On the other hand, when it's low, it results in rainfall.

How do oxygen and carbon dioxide play different roles in the ocean?
In the ocean, For respiration, marine organisms use oxygen, which converts carbohydrates into energy and produces carbon dioxide and water as byproducts.
For marine life, dissolved oxygen and carbon dioxide are essential. Through the process of photosynthesis, marine plants utilize dissolved carbon dioxide, sunlight, and water to produce carbohydrates. The water gets oxygen from this process. All marine organisms respire with oxygen, which breaks down carbohydrates into energy and produces carbon dioxide and water as byproducts. These organs are utilized by fish and other marine animals with gills to extract oxygen from seawater.

Explain how the tructure of a cell allow localization of reaction, protection from reactive molecule, and greater efficiency of cellular procee than a bacterial cell
A eukaryotic cell's structure allows for the localization of reactions because there are areas within the cell where particular enzymes colocalize.
Structural barriers are also used to protect against reactive molecules, and the division of work in this cell allows for greater efficiency of cellular processes than in a bacterial cell. In a eukaryotic cell, the phrase "subdivision of work" refers to the existence of several cell compartments, such as those connected to certain organelles that offer an appropriate medium for carrying out specific reactions, such as the presence of hydrolytic enzymes in lysosomes. As a result, according to the findings, division of labour is essential for eukaryotic cells to carry out various activities, which translates to greater metabolic efficiency when compared to bacteria.

Answer:
A terrarium with a plant and a snail
Explanation:
This is because snail uses oxygen for cellular respiration and releases carbondioxide as by product.
Where as plants uses carbondioxide exhaled for photosynthesis in the presence of light energy and chlorophyll with water to produce glucose and oxygen. Therefore cycle if oxygen and carbondioxide gases is continuous.

What are examples of genetic and environmental variation?
Examples of genetic and environmental variation
A dog's weight is influenced by both ambient factors, such as what it consumes, and hereditary factors, such as its genes. A sunflower's height is influenced by its genes as well as how much light and water it receives.The variety in DNA sequence seen in each of our genomes is referred to as genetic variation. We are all different from one another in terms of our hair color, complexion tone, and even the form of our features due to genetic variance.
Genes take on various shapes, or alleles, as a result of genetic variation. People with blue eyes, for instance, have one allele of the eye color gene, whereas those with brown eyes will have a different allele of the gene.
It is possible to consider that some genetic control is present in environmental variation (VE), which is variation in phenotype that cannot be accounted for by genetic variation or discernible genetic differences.

What is a substitution deletion and insertion point mutation?
Insertion mutation occurs when an extra base pair is added to a sequence of bases.
In general, a Point mutation refers to alteration in a single base pair of DNA by substitution, deletion, or insertion of a single nitrogenous base. Most common example of point mutation is sickle cell anemia. that consists of mutation in a single base pair in the beta-globin chain of hemoglobin pigment in the blood cells. Thus, An insertion can involve the addition of any number of nucleotides, that can be a single nucleotide or an entire piece of a chromosome.
An insertion is a point mutation in which one or more base pairs is added to a DNA sequence. Point mutations is further divided into silent mutations, missense mutations, and nonsense mutations.

What will be the result offspring of plants with homozygous tall and heterozygous tall?
When a heterozygous tall (Tt) crosses with a homozygous tall (TT), 50% of the offspring are homozygous tall and 50% are heterozygous tall.
When the same alleles of a gene are found on both homologous chromosomes, a cell is said to be homozygous for that gene.
A person who has two copies of the allele that codes for the dominant characteristic is said to be homozygous-dominant for that trait. This allele, which is sometimes referred to as the "dominant allele," is typically denoted by the uppercase version of the letter used for the associated recessive characteristic (such as "P" for the dominant allele producing purple flowers in pea plants). An organism's genotype is symbolized by a doubling of the trait's symbol, such as "PP," when it is homozygously dominant for that trait.
When a diploid organism's cells have two distinct alleles of a gene—one wild-type allele and one mutant allele—they are said to be heterozygous at that gene locus.

Meiosis produces our sex cells or gametes. (eggs in females and sperm in males).
O true
O false
Answer:
True
Explanation:
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.
True. Meiosis produces our sex cells or gametes.
What is meiosis?Meiosis is a type of cell division that occurs in sexually reproducing organisms to produce haploid gametes (sperm and eggs) with half the number of chromosomes as the parent cell. It involves two successive cell divisions, known as meiosis I and meiosis II, each of which consists of a series of stages, including prophase, metaphase, anaphase, and telophase.
During meiosis I, homologous chromosomes pair up and exchange genetic information in a process called crossing-over, which increases genetic diversity. The paired homologous chromosomes then separate and move to opposite poles of the cell, resulting in two daughter cells that have half the number of chromosomes as the parent cell.
In meiosis II, the sister chromatids of each chromosome separate, resulting in four haploid daughter cells with unique combinations of genetic information.

Evaluate the structure and function of the respiratory system to allow for passive transport for gas exchange
The respiratory system allows for passive transport for gas exchange as the body receives oxygen from the outside air; Additionally, waste gases such as carbon dioxide and water vapor are released outside the body into the air.
Respiration: The life-sustaining process in which gases are exchanged between the body and the surrounding atmosphere is known as gas exchange. More specifically, oxygen enters the body from the outside air; and waste gases like carbon dioxide and water vapor are released into the air outside the body. The respiratory system is primarily responsible for respiration. The exchange of gas is the other process. This is the biochemical process by which carbon dioxide and other waste gases diffuse from the blood into the air and oxygen diffuses from the air into the blood.
