Which cellular change in an organism could be inherited by the next generation?
Answer:
Changes in DNA result in mutations, which may be beneficial, neutral, or deleterious to the organism. If these changes occur to DNA in sperm or egg cells, they could be passed onto the next generation. Evolution consists of changes in the heritable traits of a population of organisms as successive generations replace one another.

Which of the following is a true statement about extinction?
A. Extinction is the death of a species or a larger taxonomic group.
B. It is estimated that presently we are losing hundreds of species every year due to human activities.
C. It is estimated that as much as 38% of all species, including most primates, birds, and amphibians, may be in danger of extinction before the end of the century.
D. All of the statements about extinction are true.
E. Many extinctions are associated with climate change.
Answer:
Extinction is defined as the complete elimination or termination of one of a kind of organisms or different taxa, generally species. The extinction of species can be due to human activities, climate change, loss of habitats, and other natural causes. Hence, the correct option is D.
Explanation:
Extinction is the end of a certain group, taxa, phylum, or most prominently species. There are several reasons for the extinction of species or larger taxonomic group, such as human activities, the introduction of dangerous species, loss and destruction of habitats, illegal trafficking, climate change, and human activities.
Human activities such as deforestation, urbanization, and mining are some of the major causes of the loss of species and their extinction. Due to these activities, hundreds and thousands of floras and faunas are on the verge of extinction.
Approximately more than a thousand species have been extinct over the past 500 years. Almost 38 percent of the known species have been extinct or will be extinct, which includes primates, birds, animals, and amphibians. Some of the examples of extinct species are Dodo, passenger pigeon, mammoth, and Pierolapithecus.
Climate change is one of the major reasons for the loss of biodiversity. Recent research has estimated that the majority of the species will be lost over the next fifty to 50 years.

what type of ecosystem service is the bee.
A. Provisioning
B. Regulating
C. Supporting
D. Cultural
Answer:
Provisional (livelihood framework)
Regulating services (ecosystem cascade framework)
Please read explanation.
Explanation:
The type of ecosystem service the bee offers includes pollination and this falls under regulating service.
It also offers food and medicine and thus also offer provisioning ecosystem service
Wild bees provide a broad spectrum of
ecosystem services that range from provisioning to regulating to cultural.
Provisioning ecosystem services is the focus when using a livelihoods framework but regulating ecosystem services are also often present if using the ecosystem cascade framework

Why are scientific journals considered a superior resource compared to other sources of scientific information?
Scientific journals are generally specialized for distinct academic fields or subdisciplines, and they are the most important way of communicating research findings.
In order to acquire a deeper knowledge of the facts and conclusions, the research frequently challenges prevalent assumptions and the research data given in the published research findings.Scientists disseminate these research findings in scientific journals to make it publicly available to the masses.Scientists describe the study they're building on in scientific publications and journals, as well as their research methodologies, datasets and data processing tools, and their data interpretation.On the other hand;
Scientific information is concerned with investigating the characteristics and behavior of information, the forces influencing the flow of information, and how it is being processed for optimal usability and usefulness.
It deals with the creation, gathering, categorization, retention, retrieval, interpretation, transmission, and usage of data.Thus, from the above explained concept we can conclude and agree that:
Scientific journals are far considered superior resources as compared to the sources of scientific information due to the fact that it is scientific journals are peer reviewed(i.e. experts in the field have used different research findings and methodologies) for its validation.

According to the graphs of a marine food chain, what statement(s) describe what happened to the sea otter population after the
introduction of killer whales? Select all that apply.

A)
Sea otter populations migrated to warmer waters.
B)
Sea otter populations preyed upon fewer sea urchins.
9
Sea otter populations decreased with the addition of a predator.
D)
Sea otter populations increased as the producer level increased.
E)
Sea otter populations increased in the presence of an additional predator.
Answer:
B and C
Explanation
These are correct I did it in usatestprep.
Sea otter populations preyed upon fewer sea urchins. Sea otter populations decreased with the addition of a predator. Hence option B and C is correct.
What are predator?Predator is defined as an organism that mostly hunts and consumes other organisms for food. Predators have a significant impact on an ecosystem. By dispersing seeds and nutrients from foraging, they alter the ecosystems' structure. Carnivores, or animals that only consume other animals, include predators. Scavengers are predators that cannot always kill their own prey and are classified as predators.
The number of sea otters declined, the number of sea urchins increased, and the amount of kelp also decreased when orcas began eating sea otters in the kelp forest habitat. Because sea urchins eat kelp and sea otters eat sea urchins, this is the case.
Thus, sea otter populations preyed upon fewer sea urchins. Sea otter populations decreased with the addition of a predator. Hence option B and C is correct.

All of the following are examples of maintaining homeostasis except:
O A drop in body temperature triggers shivering which generates heat; an increase in body temperature triggers
sweating which releases heat.
© By opening and closing pores in their leaves, plants continuously exchange oxygen and carbon dioxide with
the atmosphere.
O A cancerous tumor continues to grow larger and then metastasizes, spreading to new areas of the body.
O Feelings of hunger and then fullness affect the length of time between meals and quantity of food you eat,
keeping your weight near a "set point."
0 A sensor detects CO 2 levels in the blood and triggers an increase or decrease in the rate of breathing.
In biology, homeostasis refers to the mechanisms by which biological systems maintain an internal state of steady conditions. The state of homeostasis is fundamental to ensure the survival of biological systems.
All of the examples above are biological responses for maintaining homeostasis EXCEPT a cancerous tumor continues to grow larger and then metastasizes, spreading to new areas of the body.In cancer, the homeostasis of the system is lost and then cancer cells proliferate in an uncontrolled fashion, thereby leading to metastasis.Normal cells lose their homeostasis and convert into cancer cells by accumulating mutations that lead to the inactivation of tumor suppressor genes and/or activation of oncogenes.Learn more in:
