Evolution is any modification or change in the organism's characteristics over many generations. The most recent evolution within Homo sapiens populations is about 50,000 years ago. This refers to evolutionary adaptation, sexual and natural selection, and genetic drift.
Humans are still undergoing evolution. Changes to adapt to environment is a genetic change and therefore considered as evolution. Blue eyes is considered as an evolutionary trait of humans recently. It came from a mutation from an ancestor 6,000-10,000 years ago. This just means that humans will continue to evolve because evolution is considered as a slow process that will take many generations.

It's needed to consider that we have two kinds of cells: somatic cells (which have 2 chromosomes inherited from our parents; 2n), and sexual cells (which have only one chromosome, inherited only from one of our parents; n). This is crucial to understand that somatic cells, whose genetic information we do not inherit, and sexual cells, whose genetic information we do inherit, differ in how they divide themselves. The first one, although they divide themselves, they can't pass a mutation to the offspring, while sexual cells can do, or the B option, which states "cells that are produced when the mutant cell divides".

Which describes symbiosis?A. Two organisms belonging to different species live closely together and have non-specific interactions.B. Two organisms belonging to the same species living in the same area. One organism leeches resources from the other one.C. Two organisms belonging to different species live closely together and have specific interactions.D. Two organisms belonging to the same species living in the same area. They fight to have access to limited resources.
Symbiosis is a kind of ecological relationship where two or more species are closely related in terms of their living habits; they reciprocally benefit from these interactions, for example, they provide each part of the symbiosis with nutrients.
There are too many symbiotic relationships in nature, one of them we can find in organisms such as anemones, and clownfishes; in whale sharks and other fish species that tend to seal the oceans with them, and in pollination, being plants and insects, as we can see in the following pictures:
Considering this, we can say that the correct answer to the question is the third one: C. Two (or more) organisms belonging to different species live closely together and have specific interactions.

32. Human activities continue to place strains on the environment. One of these strains is the loss of biodiversity. Explain what this problem is, and describe some ways that humans are involved in both the problem and the possible solutions. In your answer be sure to state: . the meaning of the term biodiversity • one negative effect on humans if biodiversity continues to be lost • one practice that could be used to preserve bio- diversity in New York State
Biodiversity has been declining at an alarming rate in recent years, mainly due to human activities, such as land use changes, pollution, and climate change.
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water. These negative impacts can affect human behavior and can prompt mass migrations or battles over clean water.
At least, we need to be aware of all the factors that contribute to this:
Global Warming. ...Climate Change. ...Genetic Modification. ...Ocean Acidification. ...Water Pollution. ...Overfishing.Humans depend upon biodiversity for survival, such as for the foods we eat, medicines we use to stay healthy, and materials we wear or use to build our homes. These services are the tangible products or items that we and other species consume for survival. human beings have to survive a lot for these resources if biodiversity o our planet earth is facing any such serious threat.

In an ecosystem with four levels—producers, primary consumers, and two higher-level consumers—describe where the decomposers operate within the context of these trophic levels. Provide at least two examples.What trophic levels do decomposers act on? What are examples of how decomposers act on two different trophic levels?
The Decomposers which decompose the organic matter from dead plants and animals occupy the last trophic level or the top of the ecological pyramid, the most common examples of decomposers are microorganisms like bacteria, and fungi.
For example, plants that can make their food through the process of photosynthesis are called producers, consumers are of three types herbivores carnivores, omnivores based on their consumption, and decomposers are classified by the type of organic matter they break down.

In a feedback loop the specific variables that is changing and that the body is regulating is called the?
The stimulus or physiological variables is the item to be regulated, the maintenance of the feedback loops for the body regulation is called homeostasis (internal activity balance) that is a process that controls the stimulus to each function and how they triggers the response from the body activity. Receptors detects the changes in stimulus and Integrators compare the variable in relation to a set point to singnal the effectors to generate a physiological response.
Somo of the most showed examples of the homeostasis and the feedback loops are:
-Control of body temperature;
-Control of blood glucose.
Resume:
-The name of the process that controls the balance of the physiological variables of the body is: Homeostasis;
-The responsible to start a feedback loop is: the Stimulus (positive or negative);
-The stages for a feedback are: Stimulus ---> Receptors ----> Integrators -----> effectors;
Therefore, for this process the variable that changes in a feedback loop is the stimulus.

Dexter is a student who has learned about the neritic zone. His teacher has given him names of components of the abiotic and biotic factors. He has to categorize them. In which categories would the sea turtle fall?hardshell substrate temperature detritivore reptile
- Biotic factors are living organisms that take part in an environment, for example, plants and animals are biotic factors.
- Abiotic factors are all non-living parts of an environment, for example, the temperature, the soil, the sunlight, etc.
The shell is the part of a living organism, so it can be classified as a biotic factor.
A reptile is an animal member of the class Reptilia, they can be classified as biotic factors.
The sea turtle is a living organism, so it can be classified as a biotic factor.
The temperature is a non-living part of the environment, it can be classified as an abiotic factor.
The substrate is the base where living organisms live, for example, the bottom of the marine habitats formed by rocks, sand, or gravel), it can be classified as an abiotic factor.
Detritivores are organisms that feed on dead organisms and decomposed matter, they can be classified as biotic organisms.
Would the DNA of Corynebacteriumtuberculostearicum and Acinetobacter baumanniidetected by polymerase chain reaction make aneasily recognized antigen?
No, DNA won't make an easily recognized antigen because the basic structure of DNA is similar to all microbes, so DNA won't be enough to specifically recognize these two microbes.
An antigen in immunology is a molecule, molecular structure, foreign particle, pollen grain, or other foreign substance that may attach to a particular antibody or T-cell receptor. Antigens present in the body might cause an immunological reaction. The word "antigen" originally referred to something that produces antibodies. Proteins, peptides (chains of amino acids), polysaccharides (chains of monosaccharides/simple sugars), lipids, and nucleic acids can all be considered antigens.
Antibodies and T-cell receptors are examples of antigen receptors that can identify an antigen. Immune system cells produce a variety of antigen receptors, giving each cell a specificity for a single antigen. Only lymphocytes that are able to detect an antigen are activated and enlarged after being exposed to it, a process known as clonal selection.
