Individuals with beneficial traits are more likely to survive and reproduce.

Individuals within a population can have different traits because of genetic variation.

Individuals with beneficial traits are more likely to survive and reproduce in a changing environment.

Species become more different from their ancestors over time.

Fossil record shows that different species have evolved over time; DNA sequences show that different species share similar genes; Anatomy and embryology show that different species have similar structures.

The fossil record shows that fish evolved into amphibians, which evolved into reptiles, which evolved into mammals; DNA sequences show that humans and fish share many similar genes; The embryos of humans and fish have many similar structures.

1. Natural selection is the process by which individuals with certain traits re more likely to survive and reproduce than individuals with other traits. This is because the individuals with the beneficial traits are better able to compete for resources, such as food and mates.

2. This means that there are different versions of genes in the population. Some of these genes give individuals an advantage, such as being able to swim faster or see better.

3. Natural selection and changes in the environment can both contribute to adaptation. For example, if the environment becomes warmer, then individuals with traits that help them to cool down, such as sweating, will be more likely to survive.

4. The adaptation of species over time is what drives evolution. As species adapt to their environment, they become more different from their ancestors. Over millions of years, these differences can become so great that the species are no longer recognizable as being related.

5. There are many lines of evidence that support the theory of common ancestry. Three of the most important lines of evidence are the fossil record, DNA sequences, and anatomy and embryology. The fossil record shows that different species have evolved over time. DNA sequences show that different species share similar genes. Anatomy and embryology show that different species have similar structures and development.

6. Some observations of patterns seen in the fossil record, DNA sequences, anatomy, and embryology that can help explain the argument that humans are related to fish:

The expected phenotypic ratio of offspring from two spotted hamsters with codominant black and white fur is 1:2:1.

When two spotted hamsters mate, each parent can pass on either the black or white allele to their offspring. Therefore, there are four possible allele combinations: black from both parents, white from both parents, black from one parent and white from the other, or white from one parent and black from the other. These four allele combinations result in four possible phenotypes: all black, all white, black and white spotted, or black and white striped. The phenotypic ratio of these four possible outcomes is 1:2:1, with one each of the all-black and all-white phenotypes, two of the spotted phenotype, and no striped phenotype since black and white fur are codominant.

What is neuron?

An electrically excitable cell known as a neuron, neurone, or nerve cell communicates with other cells through specialized connections known as synapses. With the exception of sponges and placozoa, the neuron is the primary element of nervous tissue in all animals. Plants and fungus are examples of non-animals that lack nerve cells.

In general, three types of neurons are distinguished by their functions. Signals are sent to the spinal cord or brain by sensory neurons in response to stimuli like touch, sound, or light that influence the cells of the sensory organs. In order to control everything from muscular contractions to glandular production, motor neurons receive instructions from the brain and spinal cord.

The adage "When completing a risk assessment of a pathogen, the genus alone (i.e. Mycobacterium) is sufficient to complete the review" is TRUE.

What is Mycobacterium?

Mycobacterium is a genus of bacteria that includes several species, some of which can cause human diseases such as tuberculosis, leprosy, and Mycobacterium avium complex (MAC) infections. These bacteria are characterized by a waxy, lipid-rich cell wall that makes them resistant to many common disinfectants and antibiotics. Mycobacterium tuberculosis, the species that causes tuberculosis, is a significant global public health threat, causing millions of infections and deaths each year. In addition to causing human diseases, Mycobacterium species are also found in the environment and can infect animals, including livestock and wildlife.

A risk assessment is an evaluation of the likelihood and potential consequences of a specific hazard or threat, such as a pathogenic microorganism. The goal of a risk assessment is to identify and evaluate the risks associated with the hazard in question, and to develop strategies to mitigate or manage those risks.

When conducting a risk assessment of a pathogen, the focus is on the characteristics of the organism that make it hazardous, such as its ability to cause disease, its virulence, and its resistance to treatment or disinfection. These characteristics are generally associated with the genus of the pathogen, rather than the strain or specific subtype.

The protein substances produced by plasma cells that were cloned from B lymphocytes in response to the presence of foreign material in the body are b. Antigens

Antigens are molecules or substances that might cause the body to react with immunity. This suggests that because your immune system does not recognise the chemical, it is making an effort to fight it. An environmental substance, such as chemicals, microorganisms, viruses, or pollen, can act as an antigen. B lymphocytes, a kind of white blood cell, recognize antigens when they enter the body because of their distinct antigen receptors.

Following this, B lymphocytes go through a process known as clonal expansion when they multiply and transform into plasma cells. Large quantities of antibodies, which are specialized proteins that naturally target and neutralise the antigens, are produced and secreted by these plasma cells.

In terms of development, this is an example of complete metamorphosis.

Complete metamorphosis is a developmental process that involves distinct stages: egg, larva (caterpillar), pupa (chrysalis), and adult (butterfly). During complete metamorphosis, the organism undergoes significant changes in body structure, behavior, and ecological role as it progresses through each stage.

The transition from a caterpillar to a butterfly involves a dramatic transformation within the pupal stage, where the larval tissues are broken down and reorganized into the adult form. This process allows for the specialization of each stage to fulfill different ecological functions, such as feeding and growth as a caterpillar and reproduction as an adult butterfly. Complete metamorphosis is characteristic of insects like butterflies, moths, beetles, and flies.

According to the 10% rule of energy transfer, some of the energy will flow from rabbits at second trophic level to the trophic level that includes foxes.

The  10% rule of energy transfer states that when energy has to be passed from a lower trophic level to a higher trophic level i.e., from producers to consumers or from primary consumers to secondary consumers, only 10 % of the total energy is transferred. The rest is utilized by the organism itself or lost during respiration and other processes.

Trophic level is the hierarchical position of an organism in the food chain or ecological pyramids. In a food chain, the lower most trophic level can only be of producers or detritivores.

so these means the hydrogen bond between them are hydrolyzed by enzyme

so we see the effect of enzyme on DNA

Answer:

Enzymes help speed up chemical reactions in the human body. They bind to molecules and alter them in specific ways. They are essential for respiration, digesting food, muscle and nerve function, among thousands of other roles.

Explanation:

The energy flow in this biotic community would be from the plants to the snails, small fish, and other organisms in the community, following the food chain.

In this biotic community, energy flows from the sun to the plants through photosynthesis. The plants convert the energy from sunlight into organic molecules, which are then consumed by the snails and small fish.

The snails and small fish are then consumed by larger fish, which in turn may be consumed by predators such as birds or mammals.

The energy flow in this biotic community can be represented by a food chain, which is a linear sequence of organisms showing the flow of energy from one trophic level to the next. In this case, the food chain might look something like this:

Sunlight --> Plants --> Snails --> Small Fish --> Larger Fish --> Predators

At each trophic level, some of the energy is lost as heat due to metabolic processes such as respiration, digestion, and movement. This means that the amount of energy available to organisms at higher trophic levels is lower than at lower trophic levels.

Overall, the energy flow in this biotic community is driven by the conversion of sunlight into organic molecules through photosynthesis, and the subsequent transfer of energy from one organism to another through consumption.

Explanation:

Answer: hypotonic solution

Explanation: Plant cells have a cell wall around the outside than stops them from bursting, so a plant cell will swell up in a hypotonic solution, but will not burst.

Cell Biology: Parts of the cell. Organelles.

The endoplasmic reticulum is an organelle found just outside the nucleus that is made of several interconnected cisternae, which membranes are continuous with the outer nuclear membrane.

It has two sections: the rough endoplasmic reticulum, which has ribosomes on its surface, and the smooth endoplasmic reticulum.

Basically, the endoplasmic reticulum synthetizes proteins and membrane lipids, and then sends them to the place that needs them.

In turn, the Golgi body or Golgi complex is a different organelle that is also made of cisternae, and where the proteins sent from the endoplasmatic reticulum are processed and modified before reaching their final destination.

This means the correct answer would be B. The Golgi apparatus receives proteins from the endoplasmic reticulum that it can modify or store for later use.
